    Transradial approach (TRA) for percutaneous coronary interventions (PCIs) is a common alternative to transfemoral approach associated with lower complications. However, a limitation of TRA is the use of large caliber guiding catheters due to the small size of the radial artery. The sheathless guiding catheter system that is in diameter 1-2 French (Fr) smaller than the corresponding introducer sheath may overcome these difficulties. From January 2010 through December 2010 in 5 Italian high-volume hospitals, 213 consecutive patients who underwent TRA-PCIs using the sheathless Eaucath guiding catheter system because of small radial artery caliber (Group 1) or undergoing bifurcation PCIs (Group 2) were enrolled in this registry. In patients of Group 1 (n = 79), a 6.5-Fr sheathless guiding catheter was employed, whereas in patients of Group 2 (n = 134) a 7.5 Fr was used. Among the 213 patients enrolled, 270 vessels were treated for 316 lesions. No procedures required conversion to a conventional guiding catheter system. There were significantly more female patients in Group 1, and they were, older, shorter, and thinner than patients in Group 2. No cases of major vascular complications were observed in either groups. During procedures, adjunctive devices employed included intravascular ultrasound, thrombectomy catheters, and distal protection systems. The use of the sheathless guiding catheter system is feasible for TRA-PCIs in case of small radial artery caliber or intended coronary bifurcation intervention. ©2011, Wiley Periodicals, Inc.

    Secondary prevention strategies after percutaneous coronary intervention (PCI) include statins and dual anti-platelet therapy, however there are significant gaps between guidelines and practice. Contemporary PCI practice requires comprehensive data collection to allow dynamic auditing and benchmarking of key performance and safety indices. Genesis HeartCare is Australia's largest collaborative venture of cardiologists, practising at over 40 public and private hospitals. We hypothesised that measurement and local reporting of data would improve patient outcomes through improving compliance with guideline therapies. Real-time benchmarking via a national clinical quality and outcomes register, the Genesis Cardiovascular Outcomes Registry (GCOR-PCI). GCOR-PCI prospectively collected clinical, procedural, medication and outcomes data for 6720 consecutive patients undergoing PCI from 10 private hospitals across Australia. Key performance outcomes benchmarked against the aggregated study cohort and international standards were reported to individual sites. The main outcome measure was compliance with guideline medications (statins, anti-platelet agents). Early data identified specific practice patterns associated with lower rates of statin therapy post-PCI, which led to changes in practice. Between the first and latest year of data collection there was significant improvement in the rates of statin therapy at discharge (92.1 vs. 94.4% p<0.03) and 12 months post-PCI (87.0 vs. 92.2% p<0.001) and of antiplatelet therapy at 12 months (90.7 vs. 94.3% p<0.001). This large-scale collaboration provides a platform for the development of quality improvement initiatives. Establishment of this clinical quality registry improved patient care by identifying and monitoring gaps in delivery of appropriate therapies, driving key practice change.

    To evaluate percutaneous coronary intervention (PCI) practice trends and 12-month outcomes in Australia in the era of drug-eluting stents (DES). Prospective study of consecutive patients undergoing 9204 PCIs between 1 April 2004 and 31 March 2008 at seven Victorian public hospitals. Temporal trends in baseline characteristics and in-hospital and 12-month clinical outcomes including death, myocardial infarction (MI), target vessel revascularisation (TVR) and composite major adverse cardiac events (MACE), from year to year. Between 2004-2005 and 2007-2008, the mean age of patients undergoing PCI was stable (65 ± 12 years), and comorbidities such as hypertension, hyperlipidaemia, peripheral arterial disease and stroke increased (P < 0.05). There were fewer elective and more urgent PCIs, especially for MI < 24 hours (17.6% in 2004-2005 to 27.2% in 2007-2008, P < 0.01). Overall stent use remained high (mean, 94.6%), but use of DES declined steadily (53.9% in 2004-2005 to 32.0% in 2007-2008, P < 0.01), despite increases in complex lesions. Planned clopidogrel therapy of ≥ 12 months after insertion of DES increased from 54.7% in 2004-2005 to 98.0% in 2007-2008 (P < 0.01). The overall procedural success rate was high (mean, 95.9%), and 12-month rates of mortality (3.8%), MI (4.8%), TVR (6.8%) and stent thrombosis (1.8%) remained low. Selective use of DES was an independent predictor of freedom from MACE at 12 months (odds ratio, 0.68; 95% CI, 0.56-0.81). Use of DES declined steadily from 2004-2005 to 2007-2008, despite increasing patient risk profile and lesion complexity. Procedural success remained high and 12-month adverse outcomes remained low, with increasing use of prolonged dual antiplatelet therapy.

    This retrospective multicenter registry evaluated the safety and feasibility of left ventricular (LV) support with the Impella 2.5 (Abiomed Europe GmbH, Aachen, Germany) during high-risk percutaneous coronary intervention (PCI). Patients with complex or high-risk coronary lesions, such as last remaining vessel or left main lesions, are increasingly being treated with PCI. Because periprocedural hemodynamic compromise and complications might occur rapidly, many of these high-risk procedures are being performed with mechanical cardiac assistance, particularly in patients with poor LV function. The Impella 2.5, a percutaneous implantable LV assist device, might be a superior alternative to the traditionally used intra-aortic balloon pump. The Europella registry included 144 consecutive patients who underwent a high-risk PCI. Safety and feasibility end points included incidence of 30-day adverse events and successful device function. Patients were older (62% >70 years of age), 54% had an LV ejection fraction < or = 30%, and the prevalence of comorbid conditions was high. Mean European System for Cardiac Operative Risk Evaluation score was 8.2 (SD 3.4), and 43% of the patients were refused for coronary artery bypass grafting. A PCI was considered high-risk due to left main disease, last remaining vessel disease, multivessel coronary artery disease, and low LV function in 53%, 17%, 81%, and 35% of the cases, respectively. Mortality at 30 days was 5.5%. Rates of myocardial infarction, stroke, bleeding requiring transfusion/surgery, and vascular complications at 30 days were 0%, 0.7%, 6.2%, and 4.0%, respectively. This large multicenter registry supports the safety, feasibility, and potential usefulness of hemodynamic support with Impella 2.5 in high-risk PCI.

    Few data exist on temporal evolution of antithrombotic agent use in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) in Italy. We sought to compare data from the most recent prospective, multicenter, nationwide registries conducted in Italy, namely EYESHOT and SCOPE. EYESHOT enrolled 2585 consecutive ACS patients, both ST-segment elevation myocardial infarction (STEMI) and non-ST elevation ACS (NSTE-ACS), admitted to 203 Italian coronary care units over a 3-week period (2-22 Dec 2013 and 27 Jan-16 Feb 2014). Among patients enrolled in EYESHOT, 1755 (67.9%) underwent PCI (52.6% with STEMI and 47.4% with NSTE-ACS). In the SCOPE registry, a total of 1363 patients undergoing PCI were enrolled over 3 months (15 Feb-15 Apr 2016) in 39 Italian cath lab centers at medium to high PCI volume: 331 (24.3%) with a diagnosis of STEMI and 1032 (75.7%) with a diagnosis of NSTE-ACS. Over 2 years, the use of clopidogrel in the cath lab significantly decreased (from 11% to 8% in STEMI; p=0.06 and from 9% to 5% in NSTE-ACS; p=0.0002), while the administration of ticagrelor dramatically increased (from 14% to 37%; pSCOPE registries, a significant increase in the use of novel P2Y12 receptor inhibitors was observed, both at the time of PCI and at discharge.

    Mozec™ CTO is a novel semicompliant rapid-exchange PTCA balloon catheter with specific features dedicated to treat complex coronary lesions like chronic total occlusions (CTOs). However, no data have been reported about the performance of this device in an all-comers population with complex coronary lesions. We evaluated the safety and success rate of Mozec™ CTO balloon in 41 consecutive patients with chronic stable angina and complex coronary lesions (15 severe calcified coronary stenoses, 15 bifurcation lesions with planned two-stent intervention, and 11 CTOs). Safety was assessed reporting the balloon burst rate after inflation exceeding the rated burst pressure (RBP) according to the manufacturer's reference table. Success was defined as the possibility to advance the device further the target lesion. The Mozec™ CTO balloon showed an excellent performance with a 93.3% success in crossing tight and severely calcified lesions (14/15 pts), a 93.3% success in engaging jailed side branches after stent deployment across bifurcations (14/15 pts), and a 90.9% success in crossing CTO lesions (10/11 pts). The burst rate at RBP of the Mozec™ CTO balloon was 6.7% (1/15 balloons) in the tight and severely calcified lesions, 6.7% (1/15 balloons) when dilating jailed vessels, and 9.1% (1/11 balloons) in CTOs. The novel Mozec™ CTO balloon dilatation catheter showed promising results when employed to treat complex lesions in an all-comers population. Further studies should clarify if this kind of balloon might reduce the need of more costly devices like over-the-wire balloons and microcatheters for complex lesions treatment.

    The frequency of complex percutaneous coronary interventions (PCIs) has increased in the last few years, with a growing concern on the radiation dose received by the patients. Multicenter data from large unselected populations on patients' radiation doses during coronary angiography (CA) and PCI and temporal trends are lacking. This study sought to evaluate the temporal trends in patients' exposure to radiation from CA and PCI. Data were taken from the CARDIO-ARSIF registry that prospectively collects data on all CAs and PCIs performed in the 36 catheterization laboratories in the Greater Paris Area, the most populated regions in France with about 12 million inhabitants. Kerma area product and Fluoroscopy time from 152 684 consecutive CAs and 103 177 PCIs performed between 2009 and 2013 were analyzed. A continuous trend for a decrease in median [interquartile range] Kerma area product was observed, from 33 [19-55] Gy cm 2 in 2009 to 27 [16-44] Gy cm 2 in 2013 for CA ( P <0.0001), and from 73 [41-125] to 55 [31-91] Gy cm 2 for PCI ( P <0.0001). Time-course differences in Kerma area product remained highly significant after adjustment on Fluoroscopy time, PCI procedure complexity, change of x-ray equipment, and other patient- and procedure-related covariates. In a large patient population, a steady temporal decrease in patient radiation exposure during CA and PCI was noted between 2009 and 2013. Kerma area product reduction was consistent in all types of procedure and was independent of patient-related factors and PCI procedure complexity. © 2017 American Heart Association, Inc.

    The aim of this study is to investigate the long-term relationship between revascularization technique and health status in diabetics with multivessel disease. Using the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry, we captured 1319 diabetics with multivessel disease requiring revascularization for an acute coronary syndrome (January 2009-December 2012) and reported health status using the Seattle Angina Questionnaire (SAQ) at baseline, 1, 3 and 5-years [599 underwent coronary artery bypass grafting (CABG); 720 underwent percutaneous coronary intervention (PCI)]. Adjusted analyses were performed using a propensity score-matching technique. After adjustment (including baseline SAQ domain scores), 1-year mean (95% CI) SAQ scores (range 0-100 with higher scores reflecting improved health status) were significantly greater in selected domains for CABG compared to PCI (exertional capacity: 81.7 [79.5-84.0] vs. 78.8 [76.5-81.0], P = 0.07; angina stability: 83.1 [80.4-85.9] vs. 75.0 [72.3-77.8], P quality of life [QOL]: 83.8 [81.7-85.8] vs. 77.2 [75.2-79.2] P diabetics with multivessel disease.

    The contemporary use and outcomes of excimer laser coronary atherectomy (ELCA) in percutaneous coronary intervention (PCI) are not well described. We examined the baseline clinical and angiographic characteristics and procedural outcomes of 130 target lesions in 121 consecutive PCIs (n = 116 patients) in which ELCA was performed at three United States Department of Veterans Affairs (VA) medical centers between 2008 and 2016. Mean age was 68.5 ± 9 years and 97% of the patients were men. Patients had high prevalence of diabetes mellitus (63%), prior coronary artery bypass graft surgery (41%), and prior myocardial infarction (60%). The most common target vessel was the left anterior descending (32%), followed by the right coronary artery (30%), circumflex artery (20%), and saphenous vein graft (12%). The target lesions were highly complex, with moderate/severe calcification in 62% and in-stent restenosis in 37%. The most common indication for ELCA was balloon-uncrossable lesions (43.8%), followed by balloon-undilatable lesions (40.8%) and thrombotic lesions (12.3%). Use of ELCA was associated with high technical success rate (90.0%) and procedural success rate (88.8%), and low major adverse cardiac event (MACE) rate (3.45%). Mean procedure time was 120 min (interquartile range [IQR], 81-191 min), air kerma radiation dose was 2.76 Gy (IQR, 1.32-5.01 Gy), and contrast volume was 273 mL (IQR, 201-362 mL). In a contemporary multicenter United States registry, ELCA was commonly used in highly complex lesions and was associated with high technical and procedural success rates and low incidence of MACE.

    Randomised trials indicate higher rates of stent thrombosis (ST) and target lesion failure (TLF) after percutaneous coronary intervention (PCI) with the Absorb bioresorbable scaffold (BRS) compared with modern drug-eluting stents (DES). We aimed to investigate the outcome of all Swedish patients treated with the Absorb BRS. The Absorb BRS (n=810) was compared with commonly used modern DES (n=67,909). The main outcome measure was definite ST; mean follow-up was two years. Despite being implanted in a younger, lower-risk population compared with modern DES, the Absorb BRS was associated with a higher crude incidence of definite ST at stent level: 1.5 vs. 0.6%, hazard ratio (HR) 2.38 (95% confidence interval [CI]: 1.34-4.23), adjusted HR 4.34 (95% CI: 2.37-7.94); pstent restenosis were similar for BRS and DES. Non-compliance with dual antiplatelet therapy (DAPT) guidelines was noted in six out of 12 BRS ST events. Three very late ST events occurred with the Absorb BRS. In this real-world observational study, the Absorb BRS was associated with a significantly higher risk of definite ST compared with modern DES. Non-compliance with DAPT guideline recommendations was common among Absorb definite ST events.

    Few studies have evaluated the relationship of diabetes with technical success and periprocedural complications, and no studies have compared patient-reported health status after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without diabetes. CTOs are more common in patients with diabetes, yet CTO PCI is less often attempted in patients with diabetes than in patients without. The association between diabetes and health status after CTO PCI is unknown. In the 12-center OPEN-CTO PCI registry (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Registry), patients with and without diabetes were assessed for technical success, periprocedural complications, and health status over 1 year following CTO PCI using the Seattle Angina Questionnaire and the Rose Dyspnea Scale. Hierarchical modified Poisson regression was used to examine the independent association between diabetes and technical success, and hierarchical multivariable linear regression was used to assess the association between diabetes and follow-up health status. Diabetes was common (41.2%) and associated with a lower crude rate of technical success (83.5% vs. 88.1%; p = 0.04). After adjustment, there was no significant difference between diabetic and nondiabetic patients (relative risk: 0.96, 95% confidence interval: 0.91 to 1.01). There were no significant differences in complication rates between patients with and without diabetes. Angina burden, quality of life, and overall health status scores were similar between diabetic and nondiabetic patients over 1 year. Although technical success was lower in patients with diabetes, this reflected lower success among patients with prior bypass surgery, without any significant difference in success rate after adjusting for prior bypass and disease complexity. CTO PCI complication rates are similar in diabetic and nondiabetic patients, and symptom improvement following CTO PCI is robust

    This study sought to compare the in-hospital prognostic values of the original and updated GRACE (Global Registry of Acute Coronary Events) risk score (RS) and the AR-G (ACTION [Acute Coronary Treatment and Intervention Outcomes Network] Registry and the GWTG [Get With the Guidelines] Database) RS in acute coronary syndromes (ACS). To evaluate the utility of recalculating risk after percutaneous coronary intervention (PCI) with newer RS models (NCDR [National Cardiovascular Data Registry] and EHS [EuroHeart Score] RS). Defined in 2003, GRACE is among the most popular systems of risk stratification in ACS. An updated version of GRACE has since appeared and new RS have been developed, aiming to improve risk prediction. From 2004 to 2010, 4,497 consecutive patients admitted to a single center in Spain with an ACS were included (32.1% ST-segment elevation myocardial infarction, 19.2% unstable angina). Discrimination (C-statistic) and calibration (Hosmer-Lemeshow [HL]) indexes were used to assess performance of each RS. A comparative analysis of RS designed to predict post-PCI mortality NCDR and EHS RS versus the GRACE and AR-G RS was performed in a subgroup of 1,113 consecutive patients included in the study. There were 265 in-hospital deaths (5.9%). Original and updated GRACE RS and the AR-G RS all demonstrated good discrimination for in-hospital death (C-statistics: 0.91, 0.90 and 0.90, respectively) with optimal calibration (HL p: 0.42, 0.50, and 0.47, respectively) in all spectra of ACS, according to different managements (PCI vs. conservative) and without significant differences between the 3 different RS. In patients undergoing PCI, EHS and NCDR RS (C-statistic = 0.80 and 0.84, respectively) were not superior to GRACE RS (C-statistic = 0.91), albeit in the subgroup of patients undergoing PCI who were categorized as high risk using the GRACE RS, both EHS and NCDR have contributed to decrease the false positive rate generated by using the GRACE RS.

    Current guidelines recommend surgical revascularization (coronary artery bypass graft [CABG]) over percutaneous coronary intervention (PCI) in patients with diabetes mellitus and multivessel coronary artery disease. Few data are available describing revascularization patterns among these patients in the setting of non-ST-segment-elevation myocardial infarction. Using Acute Coronary Treatment and Intervention Outcomes Network Registry-Get with the Guidelines (ACTION Registry-GWTG), we compared the in-hospital use of different revascularization strategies (PCI versus CABG versus no revascularization) in diabetes mellitus patients with non-ST-segment-elevation myocardial infarction who had angiography, demonstrating multivessel coronary artery disease between July 2008 and December 2014. Factors associated with use of CABG versus PCI were identified using logistic multivariable regression analyses. A total of 29 769 patients from 539 hospitals were included in the study, of which 10 852 (36.4%) were treated with CABG, 13 760 (46.2%) were treated with PCI, and 5157 (17.3%) were treated without revascularization. The overall use of revascularization increased over the study period with an increase in the proportion undergoing PCI (45% to 48.9%; Ptrend=0.0002) and no change in the proportion undergoing CABG (36.1% to 34.7%; ptrend=0.88). There was significant variability between participating hospitals in the use of PCI and CABG (range: 22%-100%; 0%-78%, respectively; P value treatment of adenosine diphosphate receptor antagonists at presentation, older age, female sex, and history of heart failure. Among patients with diabetes mellitus and multivessel coronary artery disease presenting with non-ST-segment-elevation myocardial infarction, only one third undergo CABG during the index admission. Furthermore, the use of PCI, but not CABG, increased modestly over the past 6 years. © 2016 American Heart Association, Inc.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Background: Novel bare metal stents with improved stent design may become a viable alternative to drug-eluting stents in certain patient groups, particularly, when long-term dual antiplatelet therapy should be avoided. Purpose: The ENERGY registry aimed to assess the safety and benefits of a cobalt–chromium thin strut bare metal stent with a passive coating in a large series of patients under real-world conditions. Methods and materials: This prospective registry recruited 1016 patients with 1074 lesions in 48 centers from April to November 2010. The primary endpoint was the rate of major adverse cardiac events (MACEs), a composite of cardiac death, myocardial infarction and clinically driven target lesion revascularization. Results: More than half of the lesions (61.0%) were type A/B1 lesions, mean lesion length was 14.5 ± 6.5 mm and mean reference vessel diameter 3.2 ± 0.5 mm. MACE rates at 6, 12 and 24 months were 4.9%, 8.1% and 9.4%, target lesion revascularization rates 2.8%, 4.9% and 5.4% and definite stent thrombosis rates 0.5%, 0.6% and 0.6%. Subgroups showed significant differences in baseline and procedural characteristics which did not translate into significantly different clinical outcomes. Specifically, MACE rates at 24 months were 13.5% in diabetics, 8.6% in small stents and 9.6% in acute coronary syndrome patients. Conclusion: The population of ENERGY reflects real-world conditions with bare metal stents being mainly used in simple lesions. In this setting, percutaneous coronary intervention using a cobalt–chromium thin strut bare metal stent with a passive coating showed very good results up to 24 months. (ClinicalTrials.gov:NCT01056120) Summary for annotated table of contents: The ENERGY international registry evaluated the safety and benefits of a cobalt–chromium thin strut bare metal stent with passive coating in 1016 patients under real-world conditions until 2 years.

    We evaluated the prognosis of deferred and revascularized coronary stenoses after fractional flow reserve (FFR) measurement to assess its revascularization threshold in clinical practice. The IRIS-FFR registry (Interventional Cardiology Research In-cooperation Society Fractional Flow Reserve) prospectively enrolled 5846 patients with ≥1coronary lesion with FFR measurement. Revascularization was deferred in 6468 lesions and performed in 2165 lesions after FFR assessment. The primary end point was major adverse cardiac events (cardiac death, myocardial infarction, and repeat revascularization) at a median follow-up of 1.9 years and analyzed on a per-lesion basis. A marginal Cox model accounted for correlated data in patients with multiple lesions, and a model to predict per-lesion outcomes was adjusted for confounding factors. For deferred lesions, the risk of major adverse cardiac events demonstrated a significant, inverse relationship with FFR (adjusted hazard ratio, 1.06; 95% confidence interval, 1.05-1.08; P <0.001). However, this relationship was not observed in revascularized lesions (adjusted hazard ratio, 1.00; 95% confidence interval, 0.98-1.02; P =0.70). For lesions with FFR ≥0.76, the risk of major adverse cardiac events was not significantly different between deferred and revascularized lesions. Conversely, in lesions with FFR ≤0.75, the risk of major adverse cardiac events was significantly lower in revascularized lesions than in deferred lesions (for FFR 0.71-0.75, adjusted hazard ratio, 0.47; 95% confidence interval, 0.24-0.89; P =0.021; for FFR ≤0.70, adjusted hazard ratio 0.47; 95% confidence interval, 0.26-0.84; P =0.012). This large, prospective registry showed that the FFR value was linearly associated with the risk of cardiac events in deferred lesions. In addition, revascularization for coronary artery stenosis with a low FFR (≤0.75) was associated with better outcomes than the deferral, whereas for a stenosis with a high FFR (≥0

    This study sought to develop a model that predicts bleeding complications using an expanded bleeding definition among patients undergoing percutaneous coronary intervention (PCI) in contemporary clinical practice. New knowledge about the importance of periprocedural bleeding combined with techniques to mitigate its occurrence and the inclusion of new data in the updated CathPCI Registry data collection forms encouraged us to develop a new bleeding definition and risk model to improve the monitoring and safety of PCI. Detailed clinical data from 1,043,759 PCI procedures at 1,142 centers from February 2008 through April 2011 participating in the CathPCI Registry were used to identify factors associated with major bleeding complications occurring within 72 h post-PCI. Risk models (full and simplified risk scores) were developed in 80% of the cohort and validated in the remaining 20%. Model discrimination and calibration were assessed in the overall population and among the following pre-specified patient subgroups: females, those older than 70 years of age, those with diabetes mellitus, those with ST-segment elevation myocardial infarction, and those who did not undergo in-hospital coronary artery bypass grafting. Using the updated definition, the rate of bleeding was 5.8%. The full model included 31 variables, and the risk score had 10. The full model had similar discriminatory value across pre-specified subgroups and was well calibrated across the PCI risk spectrum. The updated bleeding definition identifies important post-PCI bleeding events. Risk models that use this expanded definition provide accurate estimates of post-PCI bleeding risk, thereby better informing clinical decision making and facilitating risk-adjusted provider feedback to support quality improvement.

    There are limited data on the utilization and outcomes of coronary artery bypass grafting (CABG) among ST-segment-elevation myocardial infarction (STEMI) patients in contemporary practice. Using data from National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With The Guidelines between 2007 and 2014, we analyzed trends in CABG utilization and hospital-level variation in CABG rates. Patients undergoing CABG during the index admission were categorized by the most common scenarios: (1) CABG only as the primary reperfusion strategy; (2) CABG after primary percutaneous coronary intervention; and (3) CABG after fibrinolytic therapy. A total of 15 145 patients (6.3% of the STEMI population) underwent CABG during the index hospitalization, with a decrease in utilization from 8.3% in 2007 to 5.4% in 2014 (trend P value use of CABG in STEMI varied widely from 0.5% to 36.2% (median, 5.3%; interquartile range [IQR], 3.5%-7.8%; P value use of CABG, and CABG was typically performed within 1 to 3 days after angiography. Observed mortality rates appear low, suggesting that CABG might be safely performed in select STEMI patients in a timely fashion. © 2017 American Heart Association, Inc.

    Recent randomized clinical trials demonstrated that transradial approach was a preferred approach for primary percutaneous coronary intervention (PCI) in ST-elevation acute myocardial infarction (STEMI). However, clinical outcomes of transradial approach in STEMI have not been adequately evaluated yet in the real-world practice, which includes hemodynamically unstable high-risk patients. We identified 3662 STEMI patients who had primary PCI within 24 h after symptom onset and were treated by transradial (N = 471) or transfemoral (N = 3191) approach in the CREDO-Kyoto AMI registry. In the current analysis, we compared clinical characteristics and long-term outcomes between the 2 groups of patients treated by transradial approach and transfemoral approach. The prevalence of hemodynamically compromised patients (Killip II-IV) was significantly less in the transradial group than in the transfemoral group (19 vs. 25%, P = 0.002). Cumulative 5-year incidences of death/MI/stroke, and major bleeding were not significantly different between the transradial and transfemoral groups (26.7 vs. 25.9%, log-rank P = 0.91, and 11.3 vs. 11.5%, log-rank P = 0.71, respectively). After adjustment for confounders, the risks of the transradial group relative to the transfemoral group were not significant for both death/MI/stroke [Hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.83-1.59, P = 0.41] and major bleeding (HR 1.29, 95% CI 0.77-2.15, P = 0.34). In the subgroup of hemodynamically compromised patients, there were also no significant differences in the risks for death/MI/stroke and major bleeding between the 2 groups. Clinical outcomes of transradial approach were not different from those of transfemoral approach in primary PCI for STEMI in the real-world practice.

    Although more elderly patients will experience acute myocardial infarction (AMI) in coming years, the best reperfusion strategy in these patients remains unknown. The Spanish TRIANA (TRatamiento del Infarto Agudo de miocardio eN Ancianos) registry was set up to determine the feasibility of performing a randomized study of percutaneous coronary intervention (PCI) versus thrombolysis in AMI patients aged > or =75 years. The TRIANA 1 subregistry included consecutive patients of all ages with ST-segment-elevation AMI ( or =75 years (mortality, 24%), 58 (55.7%) fulfilled criteria for inclusion in a randomized study. 1) The TRIANA 1 subregistry probably reflects the reality of PCI for AMI in Spain. 2) Mortality at 1 month was associated with classic predictive factors. 3) Some 50% of patients > or =75 years old who underwent PCI could be included in a randomized study. These findings indicate that randomized study to determine the best reperfusion strategy in elderly AMI patients is feasible.

    Compared with dual antiplatelet therapy including aspirin and clopidogrel, triple antiplatelet therapy including cilostazol has a mortality benefit in patients with ST-segment elevation myocardial infarction. However, whether the mortality benefit persists in elderly patients is not clear. From 2007 to 2014, 1278 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were retrospectively analyzed. The patients were divided into four groups by age (elderly, respectively) and antiplatelet strategy (triple or dual antiplatelet therapy). We compared the mortality rates between the triple and dual antiplatelet therapy groups. There were 1052 (male, 85%; mean age, 56.3 ± 10.4 years) patients in the young group and 241 (male, 52.7%; mean age, 80.3 ± 4.5 years) patients in the elderly group. In the young and elderly groups, 220 (20.9%) and 28 (12.3%) patients were treated with triple antiplatelet therapy. During a 1-year follow-up period, 80 patients died (4.2% in the young group vs. 15.5% in the elderly group). Kaplan-Meier survival analysis revealed that triple antiplatelet therapy was associated with a lower mortality rate in the young group (log-rank, p = 0.005). Although there were more angiographic high-risk patients in the elderly group, similar mortality rates were reported (log-rank, p = 0.803) without increased bleeding rates (1 vs. 3.6% in the elderly group, p = 0.217). Triple antiplatelet therapy might be a better antiplatelet regimen than dual antiplatelet therapy for patients with ST-segment elevation myocardial infarction. Although this benefit was strong in patients aged elderly patients (aged ≥75 years).

    To determine whether it is feasible to set up a national registry, linking routinely collected data from hospital information systems (HIS), to investigate the role of cardiovascular magnetic resonance (CMR) in patients who activate the primary percutaneous coronary intervention (PPCI) pathway. Feasibility prospective cohort study, to establish whether: (1) consent can be implemented; (2) data linkage and extraction from multiple HIS can be achieved for >90% of consented patients; (3) local data can be successfully linked with hospital episode data (Hospital Episode Statistics, HES; Patient Episode Database for Wales, PEDW) for >90% of consented patients and (4) the proportion of patients activating the PPCI pathway who get a CMR scan is ≥10% in hospitals with dedicated CMR facilities. Patients from four 24/7 PPCI hospitals in England and Wales (two with and two without a dedicated CMR facility) who activated the PPCI pathway and underwent an emergency coronary angiogram. Consent was successfully implemented at all hospitals (consent rates ranged from 59% to 74%) and 1670 participants were recruited. Data submission was variable: all hospitals submitted clinical data (for ≥82% of patients); only three hospitals submitted biochemistry data (for ≥98% of patients) and echocardiography data (for 34%-87% of patients); only one hospital submitted medications data (for 97% of patients). At the two CMR centres, 14% and 20% of patients received a CMR scan. Data submitted by hospitals were linked with HES and PEDW for 99% of all consented patients. We successfully consented patients but obtaining individual, opt-in consent would not be feasible for a national registry. Linkage of data from HIS with hospital episode data was feasible. However, data from HIS are not uniformly available/exportable and, in centres with a dedicated CMR facility, some referrals for CMR were for research rather than clinical purposes. © Article author(s) (or their employer(s) unless

  9. Triple Antithrombotic Therapy after Percutaneous Coronary Intervention (PCI in Patients with Indication for Oral Anticoagulation: Data from a Single Center Registry.

    Full Text Available Antithrombotic therapy consisting of a dual anti-platelet therapy (DAPT and oral anti-coagulation (OAC with a vitamin k antagonist is often referred to as triple therapy. This combined anticoagulation is applied in patients undergoing coronary artery stent implantation while also having an indication for OAC. Triple therapy increases the risk for bleeding events compared to either DAPT or OAC alone and thereby might be associated with adverse outcomes. Clinical data on the frequency of bleeding events in patients on triple therapy from clinical trials derives from pre-selected patients and may differ from the real world patients. We report data on patient characteristics and bleeding incidence of patients dismissed on triple therapy from a single university hospital. Within the time span from January 2000 to December 2012, we identified a total of 213 patients undergoing PCI who were prescribed a triple therapy for at least 4 weeks (representing 0.86% of all patients treated. The usage of triple therapy significantly increased over the observed time period. The average CHA2DS2-VASc Score was 3.1 ± 1.1 with an average HAS-BLED score of 2.5 ± 0.86 representing a high-risk group for thromboembolic events as well as considerable risk for bleeding events. An on-treatment bleeding incidence of 9.4% was detected, with gastrointestinal and airway bleeding being the most frequent (5.1% and 1.4%, respectively. This is consistent with data from clinical trials and confirms the high risk of bleeding in patients on DAPT plus OAC. 29.0% of all patients receiving triple therapy had an indication for OAC other than non-valvular atrial fibrillation. This substantial patient group is underrepresented by clinical trials and needs further attention.

    Besides contrast-induced acute kidney injury(CI-AKI), adscititious vital organ damage such as hypoxic liver injury(HLI) may affect the survival in patients with ST-elevation myocardial infarction (STEMI). We sought to evaluate the prognostic impact of CI-AKI and HLI in STEMI patients who underwent primary percutaneous coronary intervention (PCI). A total of 668 consecutive patients (77.2% male, mean age 61.3±13.3 years) from the INTERSTELLAR STEMI registry who underwent primary PCI were analyzed. CI-AKI was defined as an increase of ≥0.5 mg/dL in serum creatinine level or 25% relative increase, within 48h after the index procedure. HLI was defined as ≥2-fold increase in serum aspartate transaminase above the upper normal limit on admission. Patients were divided into four groups according to their CI-AKI and HLI states. Major adverse cardiovascular and cerebrovascular events (MACCE) defined as a composite of all-cause mortality, non-fatal MI, non-fatal stroke, ischemia-driven target lesion revascularization and target vessel revascularization were recorded. Over a mean follow-up period of 2.2±1.6 years, 94 MACCEs occurred with an event rate of 14.1%. The rates of MACCE and all-cause mortality were 9.7% and 5.2%, respectively, in the no organ damage group; 21.3% and 21.3% in CI-AKI group; 18.5% and 14.6% in HLI group; and 57.7% and 50.0% in combined CI-AKI and HLI group. Survival probability plots of composite MACCE and all-cause mortality revealed that the combined CI-AKI and HLI group was associated with the worst prognosis (pINTERSTELLAR ClinicalTrials.gov number, NCT02800421.).

    Full Text Available Sam J Lehman, Derek P ChewDepartment of Medicine, Flinders University, South Australia, AustraliaAbstract: Bivalirudin is a member of the direct thrombin inhibitor group of anticoagulants. It has been evaluated as an alternative to unfractionated and low-molecular-weight heparins in the settings of percutaneous coronary intervention (PCI and acute coronary syndrome (ACS. Results of clinical trials to date suggest bivalirudin is a viable alternative to the use of a heparin combined with a glycoprotein (GP IIb/IIIa inhibitor in these settings. Thrombin has a central role in coagulation and platelet activation in ACS and during PCI. Its direct inhibition is an attractive target for therapy in these settings. Bivalirudin is a 20 amino acid polypeptide hirudin analog. It displays bivalent and reversible binding to the thrombin molecule, inhibiting its action. Direct inhibition of thrombin with bivalirudin has theoretical pharmacokinetic and pharmacodynamic advantages over the indirect anticoagulants. A reduction in rates of bleeding without loss of anti-thrombotic efficacy has been a consistent finding across multiple clinical trials. There may be economic benefits to the use of bivalirudin if it permits a lower rate of use of the GP IIb/IIIa inhibitors. This article reviews the pharmacology of bivalirudin and clinical trial evidence to date. There are now data from multiple clinical trials and meta-analyses in the setting of ACS and PCI. Early results from the acute catheterization and urgent intervention strategy (ACUITY trial are discussed.

    The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who are at increased surgical risk. Data from randomized trials involving patients who are candidates for either treatment strategy provide novel insight into the relative safety and efficacy of PCI for this lesion subset. Herein, we review the current data comparing PCI with CABG for left main disease, summarize recent guideline recommendations, and provide an update on technical considerations that may optimize clinical outcomes in left main PCI.

    Despite major advances in prevention and treatment, coronary artery disease (CAD) remains the leading cause of death worldwide. Whereas many sources of data are available on the epidemiology of acute coronary syndromes, fewer datasets reflect the contemporary management and outcomes of stable CAD patients. A worldwide contemporary registry would improve our knowledge about stable CAD. The main objectives are to describe the demographics, clinical profile, contemporary management and outcomes of outpatients with stable CAD; to identify gaps between evidence and treatment; and to investigate long-term prognostic determinants. CLARIFY (ProspeCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease) is an ongoing international observational longitudinal registry. Stable CAD patients from 45 countries in Europe, Asia, America, Middle East, Australia and Africa were enrolled between November 2009 and June 2010. The inclusion criteria were previous myocardial infarction, evidence of coronary stenosis >50%, proven symptomatic myocardial ischemia or prior revascularization procedure. The main exclusion criteria were serious non-cardiovascular disease, conditions interfering with life expectancy or severe other cardiovascular disease (including advanced heart failure). Follow-up visits were planned annually for up to 5 years, interspersed with 6-month telephone calls. Of the 32,703 patients enrolled, most (77.6%) were male, age (mean ± SD) was 64.2 ± 10.5 years, and 71.0% were receiving treatment for hypertension; mean ± SD resting heart rate was 68.2 ± 10.6 bpm. Patients were enrolled based on a history of myocardial infarction >3 months earlier (57.7%), having at least one stenosis >50% on coronary angiography (61.1%), proven symptomatic myocardial ischemia on non-invasive testing (23.1%), or history of percutaneous coronary intervention or coronary artery bypass graft (69.8%). Baseline characteristics were similar across the four

We sought to evaluate the prognostic impact of CI-AKI and HLI in STEMI patients who underwent primary percutaneous coronary intervention (PCI.A total of 668 consecutive patients (77.2% male, mean age 61.3±13.3 years from the INTERSTELLAR STEMI registry who underwent primary PCI were analyzed. CI-AKI was defined as an increase of ≥0.5 mg/dL in serum creatinine level or 25% relative increase, within 48h after the index procedure. HLI was defined as ≥2-fold increase in serum aspartate transaminase above the upper normal limit on admission. Patients were divided into four groups according to their CI-AKI and HLI states. Major adverse cardiovascular and cerebrovascular events (MACCE defined as a composite of all-cause mortality, non-fatal MI, non-fatal stroke, ischemia-driven target lesion revascularization and target vessel revascularization were recorded.Over a mean follow-up period of 2.2±1.6 years, 94 MACCEs occurred with an event rate of 14.1%. The rates of MACCE and all-cause mortality were 9.7% and 5.2%, respectively, in the no organ damage group; 21.3% and 21.3% in CI-AKI group; 18.5% and 14.6% in HLI group; and 57.7% and 50.0% in combined CI-AKI and HLI group.

    Percutaneous coronary intervention (PCI) has been shown to be the best reperfusion therapy for acute myocardial infarction with ST-elevation (STEMI), but data from registries show differences in patient populations and outcomes between randomized trials and real life. We sought to provide information about the current status of this treatment with a registry collecting data in Lombardy, the most densely populated region in Italy, with widespread availability of cathlabs and a well-established network for the treatment of STEMI. Patient enrollment was performed by 32 hub centres recruiting 3901 STEMI patients who underwent PCI procedures within 12 h of the onset of symptoms, of whom 3317 patients underwent primary PCI, 376 'facilitated' PCI, and 208 rescue PCI in cathlabs located, in 77% of cases, in the same hospital of admission. In-hospital and 30-day total death were 4.4 and 6.6%, respectively. At multivariate analysis independent negative predictors of 30-day mortality were Killip class 3-4, number of involved ECG leads, chronic renal failure and age, whereas positive predictors were ST resolution more than 50% and postprocedural grade 3 thrombolysis in myocardial infarction flow. LombardIMA PCI registry enrolled STEMI patients representing a real-world population treated with PCI. Findings presented in this study may provide a benchmark for similar registries undertaken in other Italian regions and may be helpful to assess future possible developments of care for STEMI patients.

    This study assessed current practices in relation to coronary risk factors, therapy and its results in patients with acute ischemic coronary syndromes (AICS) with or without ST-segment-elevation myocardial infarction [MI], from data collected in the National Registry of AICS [RENASICA] in México; Eigh teen hospitals [2nd. and 3rd level of medical attention] recruited patients for the registry, 4,253 patients were enrolled, 2,773 [65.2%] without AICSST segment elevation and 1480 [34.8%] patients with ST segment elevation MI. Chest pain was the main cause for seeking medical attention to an emergency service (90.5%) and 50% of the patients referred it in advance. AICS was mainly observed in men in their sixth decade of age. Age, ST segment depression [> 2 mm], CKMB [> 2 values above normal] and the extension of the coronary artery disease allow to predict mortality and the combination of mortality and myocardial infarction. Only 50.4% of the eligible patients with AICS and ST-segment-elevation myocardial infarction received thrombolytic therapy. Of the eligible cohort of AICS only 58% patients could an hemodynamic study be performed. In 55% of them, a percutaneous coronary intervention procedure was done (PTCA-Stent implantation). Aspirin [ASA] and heparin were prescribed in 70% of the patients at entry to the ward and the same percentage of AICS patients received ASA after discharge. Low molecular weight heparin and IIb/IIIa receptor platelet antagonists were used in a low proportion of patients. RENASICA provides information related to AICS patients that could help the mexican health authorities to apply better the health resources in the forthcoming future for the treatment of AICS.

    The practice of interventional cardiology differs between countries and regions. In this study we report the results of the first nation-wide long-term comparison of interventional cardiology in two countries using a common web-based registry. The Swedish Coronary Angiography and Angioplasty Registry (SCAAR) was used to prospectively and continuously collect background-, quality-, and outcome parameters for all coronary angiographies (CA) and percutaneous coronary interventions (PCI) performed in Iceland and Sweden during one year. The rate of CA per million inhabitants was higher in Iceland than in Sweden. A higher proportion of patients had CA for stable angina in Iceland than in Sweden, while the opposite was true for ST elevation myocardial infarction. Left main stem stenosis was more commonly found in Iceland than in Sweden. The PCI rate was similar in the two countries as was the general success rate of PCI, achievement of complete revascularisation and the overall stent use. Drug eluting stents were more commonly used in Iceland (23% vs. 19%). The use of fractional flow reserve (0.2% vs. 10%) and the radial approach (0.6% vs. 33%) was more frequent in Sweden than in Iceland. Serious complications and death were very rare in both countries. By prospectively comparing interventional cardiology in two countries, using a common web based registry online, we have discovered important differences in technique and indications. A discovery such as this can lead to a change in clinical practice and inspire prospective multinational randomised registry trials in unselected, real world populations.

  20. Impact of coronary dominance on in-hospital outcomes after percutaneous coronary intervention in patients with acute coronary syndrome.

    Directory of Open Access Journals (Sweden)

    Toshiki Kuno

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Transcatheter closure of coronary artery fistulas can be executed successfully in infants and children with few serious procedural complications. Indications for and long-term outcomes of closure of coronary artery fistulas remain poorly defined. Registries may offer the best opportunity for advancing our knowledge about uncommon interventions such as coil or device closure of coronary artery fistulas, but to do so, they must include sufficient data and evaluate factors potentially associated with salutary or adverse outcome. © 2016 Wiley Periodicals, Inc.

    Approximately 5 to 7% of patients undergoing percutaneous coronary intervention (PCI) for the treatment of coronary artery disease require chronic oral anticoagulation (OAC) on top of aspirin and a P2Y 12 receptor antagonist, mainly due to non-valvular atrial fibrillation (AF). The advent of non-vitamin K antagonist oral anticoagulants (NOACs) increased treatment options, while there is cumulative evidence that dual combination of a NOAC and a P2Y 12 receptor antagonist attenuates risk of bleeding, compared to traditional triple therapy, consisting of a vitamin K antagonist (VKA), aspirin, and a P2Y 12 receptor antagonist, without significantly compromising efficacy. Greek AntiPlatElet Atrial Fibrillation (GRAPE-AF, NCT 03362788) is an observational, nationwide study of non-valvular AF patients undergoing PCI, planning to enroll over 1-year period > 500 participants in 25 tertiary and non-tertiary PCI centers in Greece. Key data to be collected pre-discharge include demographics, detailed past medical history, and antithrombotic and concomitant treatment. Patients will be followed up at 1, 6, and 12 months post hospital discharge. Αt each follow-up visit, data on antithrombotic treatment, ischemic, bleeding, and adverse events will be collected. Study's primary endpoint is clinically significant bleeding (Bleeding Academic Research Consortium, BARC ≥ 2) at 12 months, between VKAs and NOACs-treated patients, analyzed using Cox proportional hazards models, by an intention-to-treat principle. An independent endpoint committee will adjudicate all clinical events. This study aims at providing "real-world" information on current antithrombotic treatment patterns and clinical outcome of patients with non-valvular AF undergoing PCI.

    The aim of this study was to determine how trial-based findings of EXCEL and NOBLE might be interpreted and generalizable in 'real-world' settings with comparison of data from the large-scaled, all-comer Interventional Research Incorporation Society-Left MAIN Revascularization (IRIS-MAIN) registry. We compared baseline clinical and procedural characteristics and also determined how the relative treatment effect of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) was different in EXCEL and NOBLE, compared with those of the multicenter, IRIS-MAIN registry (n=2481). The primary outcome for between-study comparison was a composite of death, myocardial infarction (MI), or stroke. There were between-study differences in patient risk profiles (age, BMI, diabetes, and clinical presentation), lesion complexities, and procedural characteristics (stent type, the use of off-pump surgery, and radial artery); the proportion of diabetes and acute coronary syndrome was particularly lower in NOBLE than in other studies. Although there was interstudy heterogeneity for the protocol definition of MI, the risks for serious composite outcome of death, MI, or stroke were similar between PCI and CABG in EXCEL [hazard ratio (HR): 1.00; 95% confidence interval (CI): 0.79-1.26; P=0.98] and in the matched cohort of IRIS-MAIN (HR: 1.08; 95%CI: 0.85-1.38; P=0.53), whereas it was significantly higher after PCI than after CABG in NOBLE (HR: 1.47; 95%CI: 1.06-2.05; P=0.02), which was driven by more common MI and stroke after PCI. In the comparison of a large-sized, all-comer registry, the EXCEL trial might represent better generalizability with respect to baseline characteristics and observed clinical outcomes compared with the NOBLE trial.

    The current state of evaluating patients with peripheral artery disease and more specifically of evaluating medical devices used for peripheral vascular intervention (PVI) remains challenging because of the heterogeneity of the disease process, the multiple physician specialties that perform PVI, the multitude of devices available to treat peripheral artery disease, and the lack of consensus about the best treatment approaches. Because PVI core data elements are not standardized across clinical care, clinical trials, and registries, aggregation of data across different data sources and physician specialties is currently not feasible.Methods and Results:Under the auspices of the U.S. Food and Drug Administration's Medical Device Epidemiology Network initiative-and its PASSION (Predictable and Sustainable Implementation of the National Registries) program, in conjunction with other efforts to align clinical data standards-the Registry Assessment of Peripheral Interventional Devices (RAPID) workgroup was convened. RAPID is a collaborative, multidisciplinary effort to develop a consensus lexicon and to promote interoperability across clinical care, clinical trials, and national and international registries of PVI. The current manuscript presents the initial work from RAPID to standardize clinical data elements and definitions, to establish a framework within electronic health records and health information technology procedural reporting systems, and to implement an informatics-based approach to promote the conduct of pragmatic clinical trials and registry efforts in PVI. Ultimately, we hope this work will facilitate and improve device evaluation and surveillance for patients, clinicians, health outcomes researchers, industry, policymakers, and regulators.

    To describe the clinical-epidemiologic profile and the process of care of the non-ST elevation acute coronary syndromes in a tertiary hospital. We analyzed the clinical information, the risk stratification and diagnostic methods, the revascularization therapy and the prescription trends at discharge, of patients with non-ST elevation acute coronary syndromes cared for in one year. Two hundred and eighty-three patients with mean age of 58 years were included (63% men). The largest number of non-ST elevation acute coronary syndromes (88.6%) was found between 50 to 59 years of age. The most common risk factor was hypertension; 82.5% of the patients had a low-intermediate TIMI score; residual ischemia was demonstrated in 37% and coronary obstructions were seen in 80 patients (70%). In 90%, a percutaneous coronary intervention was performed, mainly with drug-eluting Stents (87.5%). At discharge, even though antiplatelet agents and statins were prescribed in more than 90%, other drugs were indicated in a few more than 50% of patients. In this population, non-ST elevation acute coronary syndromes predominates in relatively young men, often with hypertension. To stratify risk, to look for residual ischemia and to revascularize with drug-eluting stents are common practices, but the evidence-based guidelines compliance is still suboptimal.

    The burden of cardiovascular diseases is anticipated to rise in developing countries. We sought to describe the epidemiology, management, and clinical outcomes of patients hospitalized with acute coronary syndromes (ACS) in three countries in western North Africa. Adult patients hospitalized with a diagnosis of ACS were enrolled in the prospective ACute Coronary Events - a multinational Survey of current management Strategies (ACCESS) registry over a 13-month period (January 2007 to January 2008). We report on patients enrolled at sites in Algeria, Morocco and Tunisia. A standardized form was used to collect data on patient characteristics, treatments and outcomes. A total of 1687 patients with confirmed ACS were enrolled (median age 59 [interquartile range 52, 68] years; 76% men), 59% with ST-elevation myocardial infarction (STEMI) and 41% with non-ST-elevation ACS (NSTE-ACS). During hospitalization, most patients received aspirin (96%) and a statin (90%), 83% received a beta-blocker and 74% an angiotensin-converting enzyme inhibitor. Among eligible STEMI patients, 42% (419/989) did not receive fibrinolysis or undergo percutaneous coronary intervention. All-cause death at 12 months was 8.1% and did not differ significantly between patients with STEMI or NSTE-ACS (8.3% vs 7.7%, respectively; Log-rank test P=0.82). Clinical factors associated with higher risk of death at 12 months included cardiac arrest, cardiogenic shock, bleeding episodes and diabetes, while percutaneous coronary intervention and male sex were associated with lower risk. In this observational study of ACS patients from three Maghreb countries, the use of evidence-based pharmacological therapies for ACS was quite high; however, 42% of the patients with STEMI were not given any form of reperfusion therapy.

    There are sparse data on the performance of different types of drug-eluting stents (DES) in acute and real-life setting. The aim of the study was to compare the safety and efficacy of first- versus second-generation DES in patients with acute coronary syndromes (ACS). This all-comer registry enrolled consecutive patients diagnosed with ACS and treated with percutaneous coronary intervention with the implantation of first- or second-generation DES in one-year follow-up. The primary efficacy endpoint was defined as major adverse cardiac and cerebrovascular event (MACCE), a composite of all-cause death, nonfatal myocardial infarction, target-vessel revascularization and stroke. The primary safety outcome was definite stent thrombosis (ST) at one year. From the total of 1916 patients enrolled into the registry, 1328 patients were diagnosed with ACS. Of them, 426 were treated with first- and 902 with second-generation DES. There was no significant difference in the incidence of MACCE between two types of DES at one year. The rate of acute and subacute ST was higher in first- vs. second-generation DES (1.6% vs. 0.1%, p < 0.001, and 1.2% vs. 0.2%, p = 0.025, respectively), but there was no difference regarding late ST (0.7% vs. 0.2%, respectively, p = 0.18) and gastrointestinal bleeding (2.1% vs. 1.1%, p = 0.21). In Cox regression, first-generation DES was an independent predictor for cumulative ST (HR 3.29 [1.30-8.31], p = 0.01). In an all-comer registry of ACS, the one-year rate of MACCE was comparable in groups treated with first- and second-generation DES. The use of first-generation DES was associated with higher rates of acute and subacute ST and was an independent predictor of cumulative ST.

    Transradial access has become popular and preferred approach in coronary interventions due to high success rate, low risk of complications and patients' comfort. However various anatomical variations and anomalies may pose technical challenge. Arteria lusoria is an uncommon condition which is technically challenging and may warrant cross-over to alternate access. We report a middle aged male presenting with acute coronary syndrome in which arteria lusoria was incidentally detected during right transradial coronary intervention.

    Coronary heart disease (CHD) is the most common cause of death globally, although mortality rates are falling. Psychological symptoms are prevalent for people with CHD, and many psychological treatments are offered following cardiac events or procedures with the aim of improving health and outcomes. This is an update of a Cochrane systematic review previously published in 2011. To assess the effectiveness of psychological interventions (alone or with cardiac rehabilitation) compared with usual care (including cardiac rehabilitation where available) for people with CHD on total mortality and cardiac mortality; cardiac morbidity; and participant-reported psychological outcomes of levels of depression, anxiety, and stress; and to explore potential study-level predictors of the effectiveness of psychological interventions in this population. We updated the previous Cochrane Review searches by searching the following databases on 27 April 2016: CENTRAL in the Cochrane Library, MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO). We included randomised controlled trials (RCTs) of psychological interventions compared to usual care, administered by trained staff, and delivered to adults with a specific diagnosis of CHD. We selected only studies estimating the independent effect of the psychological component, and with a minimum follow-up of six months. The study population comprised of adults after: a myocardial infarction (MI), a revascularisation procedure (coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI)), and adults with angina or angiographically defined coronary artery disease (CAD). RCTs had to report at least one of the following outcomes: mortality (total- or cardiac-related); cardiac morbidity (MI, revascularisation procedures); or participant-reported levels of depression, anxiety, or stress. Two review authors independently screened titles and abstracts of all references for eligibility. A lead review author

    A 45-year-old male patient presented with acute anterior wall myocardial infarction. Angiography revealed a single coronary trunk arising from the ascending aorta above the coronary sinuses and giving rise to right coronary artery, left circumflex artery and critical stenosis in the left anterior descending artery. This report also highlights the feasibility of performing percutaneous coronary intervention (PCI) in this rare anomaly and discusses the important technical considerations to be kept in mind while attempting such a case. This is the first report of such an anomalous origin of a single coronary trunk arising from ascending aorta.

    Full Text Available Coronary artery perforation is an uncommon complication in patients with coronary heart disease undergoing percutaneous coronary intervention. However, pericardial tamponade following coronary artery perforation may be lethal, and prompt treatment is crucial in managing such patients. Balloon occlusion and the reversal of anticoagulant activity are the common methods used to prevent cardiac tamponade by reducing the amount of bleeding. Herein, we discuss the pros and cons of currently used occlusion types for coronary perforation. Optimal balloon occlusion methods should reduce the amount of bleeding and ameliorate subsequent myocardial ischemia injury, even during cardiac surgery.

    Full Text Available Abstract Introduction There is a strong clinical need to provide effective stress reduction programs for patients with an acute coronary syndrome. Such programs for men have been implemented and their cardiovascular health benefit documented. For women such programs are scarce. In this report, The feasibility of a cognitive method that was recently demonstrated to prolong lives of women is tested. A setting with gender segregated groups was applied. Method The principles of a behavioural health educational program originally designed to attenuate the stress of patients with coronary prone behaviours were used as a basis for the intervention method. For the groups of female patients this method was tailored according to female stressors and for the groups of men according to male stressors. The same core stress reduction program was used for women and men, but the contents of discussions and responses to the pre planned program varied. These were continuously monitored throughout the fifteen sessions. Implementation group: Thirty consecutive patients, eleven women and nineteen men, hospitalized for an acute coronary syndrome were included in this intervention. All expressed their need to learn how to cope with stress in daily life and were highly motivated. Five groups, three groups of men and two groups of women were formed. Psychological assessments were made immediately before and after completion of the program. Results No gender differences in the pre planned programs were found, but discussion styles varied between the women and men, Women were more open and more personal. Family issues were more frequent than job issues, although all women were employed outside their homes. Men talked about concrete and practical things, mostly about their jobs, and not directly about their feelings. Daily stresses of life decreased significantly for both men and women, but more so for women. Depressive thoughts were low at baseline, and there was no

    Evidence of the clinical characteristics, treatment and outcomes among Latin American (LA) patients with acute coronary syndromes (ACS) is scarce. ACCESS, international prospective multicenter registry to evaluate risk stratification, management and outcomes in ACS (unstable angina or non-ST elevation myocardial infarction [UA/NSTEMI] or ST elevation myocardial infarction [STEMI]) in developing countries. Primary endpoint: all-cause death at 1 year; all-cause mortality within 30 days was also recorded, Patients with acute ischemic symptoms within 24 hours of symptoms onset and electrocardiographic evidence of ischemia were enrolled. Coronary artery disease was proved by positive invasive or non-invasive tests. Between 2007 and 2008, 4436 patients with ACS (2562 UA/NSTEMI and 2374 STEMI) from eight LA countries. On admission, acute symptoms were identified in 79 % and 90%, respectively. Both groups had a long delay from symptom onset to hospital arrival. Low access to pharmacological (29%) and mechanical reperfusion (32%) were observed. At admission, rates of evidence-based treatment were low in all groups. The most common in-hospital complications were heart failure (10% UA/NSTEMI and 20% STEMI) and recurrent ischemia (8% and 11%). Mortality at 30 days was 2% and 8% at 1 year. ACCESS registry provides contemporary information of patients with ACS in LA and their hospital management and subsequent clinical outcomes.

    Few studies have evaluated the prevalence and clinical outcomes of ad hoc percutaneous coronary intervention (PCI), performing diagnostic coronary angiography and PCI in the same session, in stable coronary artery disease (CAD) patients.Methods and Results:From the CREDO-Kyoto PCI/CABG registry cohort-2, 6,943 patients were analyzed as having stable CAD and undergoing first PCI. Ad hoc PCI and non-ad hoc PCI were performed in 1,722 (24.8%) and 5,221 (75.1%) patients, respectively. The cumulative 5-year incidence and adjusted risk for all-cause death were not significantly different between the 2 groups (15% vs. 15%, P=0.53; hazard ratio: 1.15, 95% confidence interval: 0.98-1.35, P=0.08). Ad hoc PCI relative to non-ad hoc PCI was associated with neutral risk for myocardial infarction, any coronary revascularization, and bleeding, but was associated with a trend towards lower risk for stroke (hazard ratio: 0.78, 95% confidence interval: 0.60-1.02, P=0.06). Ad hoc PCI in stable CAD patients was associated with at least comparable 5-year clinical outcomes as with non-ad hoc PCI. Considering patients' preference and the cost-saving, the ad hoc PCI strategy might be a safe and attractive option for patients with stable CAD, although the prevalence of ad hoc PCI was low in the current study population.

    This paper presents data on the nascence and development of the interventional cardiology service in Kazakhstan. It provides details of the structure of the Kazakhstan interventional cardiology service, staff training, the number of coronary and structural heart interventions for the period of 2010-2015, as well as the peculiarities of the capitation payment method. The number of coronary interventions is increasing year by year, though the number of intracoronary imaging techniques and intracoronary flow/pressure techniques remains inadequate. Structural heart interventions are mostly performed at tertiary hospital level, with an ever increasing number of transcatheter aortic valve implantation (TAVI) procedures.

    Vascular access complications after coronary angiography (CAG) and percutaneous coronary intervention (PCI) are known to increase morbidity, prolong hospitalization and raise hospital costs. Therefore, risk factor identification and improvement of safety strategies for vascular management are important. We aimed to assess the incidence of major vascular complications related to femoral access, and to identify potential risk factors. Over a period of six years, 23,870 index procedures (CAG) were performed in two centres, prospectively entered in the database and retrospectively analysed. Data was obtained from the Eastern Danish Heart Registry and cross-matched with data from the Danish Vascular Registry. Index procedures were defined as the first trans-femoral procedure. Demographic, procedural and mortality data, as well as information on access complications requiring surgery within 30 days were collected. Mortality data were collected for minimum 12 months. We identified 130 (0.54%) access complications requiring surgery; 65 pseudoaneurysms (0.28%), 46 arterial occlusions (0.19%), 15 hematomas (nine groin and six retroperitoneal hematomas) (0.06%), and 4 arterial dissections (0.02%). Risk factors for complications were left sided femoral access (OR 4.11 [2.29-7.37] pVascular complications related to femoral access in coronary diagnostic and interventional procedures are low (0.54%). Risk factors were left sided access, PAD, and female sex. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The management and impact of concomitant coronary artery disease in patients referred for TAVI remains contentious. We describe the prevalence, clinical impact and management of coronary artery disease (CAD) in patients in the United Kingdom TAVI Registry. All-inclusive study of patients undergoing TAVI in the United Kingdom (excluding Northern Ireland) from January 2007 to December 2011. Coronary artery disease at the time of TAVI was demonstrated on invasive angiography. 2588 consecutive patients were entered in the U.K. TAVI Registry. CAD was reported in 1171 pts with left main stem involvement in 12.4% of this cohort (n=145). Most patients were free of chest pain, but limited by dyspnoea (NYHA Class III & IV 81.9%). Angina was however more prevalent in those patients with CAD (pHeart Team in making decisions on individual patients must not be underestimated. Copyright © 2015 Elsevier Ireland Ltd.

    Acute kidney injury (AKI) complicating percutaneous coronary intervention (PCI) is associated with adverse clinical outcomes. To date, no studies have evaluated the association of blood transfusion with AKI in patients undergoing PCI. We used a retrospective cohort study of all patients with acute coronary syndrome undergoing PCI from CathPCI Registry (n=1 756 864). The primary outcome was AKI defined as the rise in serum creatinine post procedure ≥0.5 mg/dL or ≥25% above baseline values. AKI developed in 9.0% of study sample. Patients with AKI were older, more often women, and had high prevalence of comorbidities, including diabetes mellitus, hypertension, and advanced stages of chronic kidney disease at baseline. Blood transfusion was utilized in 2.2% of patients. In the overall sample, AKI developed in 35.1% of patients who received transfusion versus 8.4% of patients without transfusion (adjusted odds ratio, 4.87 [4.71-5.04]). In the subgroup of patients who sustained bleeding event and received transfusion, the rate of AKI was significantly increased across all preprocedure hemoglobin levels versus no blood transfusion. Similar findings were seen in the subgroup of patients with no bleeding event. Blood transfusion is strongly associated with AKI in patients with acute coronary syndrome undergoing PCI. Further investigation is needed to determine whether a restrictive blood transfusion strategy might improve PCI outcomes by reducing the risk of AKI. © 2016 American Heart Association, Inc.

    Coronary computed tomography angiography (CTA) is increasingly used as a test to rule out coronary artery disease (CAD) in patients with a low to intermediate pre-test probability of the disease. We used the database of the German CT registry, collected between 2009 and 2014 in a broad patient population, to analyze contemporary radiation dose associated with coronary CTA in clinical practice. The prospective observational registry included a total of 7061 patients ≥18 years, referred to 12 participating centers for a clinically indicated cardiac CT examination. All centers were cardiology units well experienced in CTA and used multi-slice CT scanners with at least 64 rows. Coronary CTA was performed in a subset of 5001 patients, 59.6 ± 11.8 years, body mass index (BMI) 26.9 ± 4.5 kg/m 2 , 38% females. Three time periods with approximately equal numbers of patients were created (01/09-03/10, 04/10-03/11, 04/11-07/14). The dose-length product of all examinations and derived effective dose in mSv (conversion factor k = 0.014) as well as the influence of patient characteristics on dose were compared for the three time periods. BMI and proportion of female patients remained stable over time, and mean heart rate decreased from 60.3 ± 9.0 to 58.5 ± 9.3 bpm from the first to the last time period (p effective dose of coronary CTA was 3.6 mSv (Q1 1.8 mSv, Q3 7.4 mSv). Within the three time periods, it declined from 5.6 (2.7, 8.6) mSv during the first to 4.8 (2.1, 8.2) mSv during the second and 2.5 (1.3, 4.6) mSv during the last time period (p dose over time, the proportion of prospectively ECG-triggered examinations increased (68, 79, 83%; p examinations with retrospective gating and no tube current modulation decreased (5.3, 4.0, 1.6%; p dose were older age, higher heart rate, and higher BMI as well as the technical factors higher mAs, higher kV, and retrospective gating.

    Full Text Available Coronary chronic total occlusion (CTO intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i.e., using fractional flow reserve. In this review we present the current literature describing the utility and efficacy of these adjunctive modalities in CTO intervention.

    Full Text Available BACKGROUND: Gender-related differences in mortality of acute coronary syndrome (ACS have been reported. The extent and causes of these differences in the Middle-East are poorly understood. We studied to what extent difference in outcome, specifically 1-year mortality are attributable to demographic, baseline clinical differences at presentation, and management differences between female and male patients. METHODOLOGY/PRINCIPAL FINDINGS: Baseline characteristics, treatment patterns, and 1-year mortality of 7390 ACS patients in 65 hospitals in 6 Arabian Gulf countries were evaluated during 2008-2009, as part of the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2. Women were older (61.3±11.8 vs. 55.6±12.4; P<0.001, more overweight (BMI: 28.1±6.6 vs. 26.7±5.1; P<0.001, and more likely to have a history of hypertension, hyperlipidemia or diabetes. Fewer women than men received angiotensin-converting enzyme inhibitors (ACE, aspirin, clopidogrel, beta blockers or statins at discharge. They also underwent fewer invasive procedures including angiography (27.0% vs. 34.0%; P<0.001, percutaneous coronary intervention (PCI (10.5% vs. 15.6%; P<0.001 and reperfusion therapy (6.9% vs. 20.2%; P<0.001 than men. Women were at higher unadjusted risk for in-hospital death (6.8% vs. 4.0%, P<0.001 and heart failure (HF (18% vs. 11.8%, P<0.001. Both 1-month and 1-year mortality rates were higher in women than men (11% vs. 7.4% and 17.3% vs. 11.4%, respectively, P<0.001. Both baseline and management differences contributed to a worse outcome in women. Together these variables explained almost all mortality disparities. CONCLUSIONS/SIGNIFICANCE: Differences between genders in mortality appeared to be largely explained by differences in prognostic variables and management patterns. However, the origin of the latter differences need further study.

    2017-05-01

    Due to its potential prognostic implications and technical complexity, revascularisation of left main coronary artery (LMCA) disease requires careful consideration. Since publication of the results of the SYNTAX study, and more recently the EXCEL and NOBLE trials, there has been particular interest in percutaneous revascularisation of the LMCA. It is becoming clear that percutaneous revascularisation of LMCA disease requires appropriate lesion preparation and carefully optimised stenting in order to offer patients a treatment option as effective as coronary artery bypass grafting. For this reason intravascular imaging, and especially intravascular ultrasound, is becoming a key procedural step in LMCA percutaneous coronary intervention. In the current review paper we analyse the role of intravascular imaging with intravascular ultrasound in LMCA percutaneous coronary intervention, focusing on the main applications in this context from lesion assessment to stent sizing and optimisation.

    Instantaneous wave-free ratio (iFR) is a new hemodynamic resting index for assessment of coronary artery stenosis severity. iFR uses high frequency sampling to calculate a gradient across a coronary lesion during a period of diastole. The index has been tested against fractional flow reserve (FFR) and found to have an overall classification agreement of 80% to 85%. Whether the level of disagreement is clinically relevant is unknown. Clinical outcome data on iFR are scarce. This study is a registry-based randomized clinical trial, which is a novel strategy using health quality registries as on-line platforms for randomization, case record forms, and follow-up. iFR-SWEDEHEART is a multicenter, prospective, randomized, controlled, clinical open-label clinical trial. Two thousand patients with stable angina or acute coronary syndrome and an indication for physiology-guided assessment of one or more coronary stenoses will be randomized 1:1 to either iFR- or FFR-guided intervention. The randomization will be conducted online in the Swedish web-based system for enhancement and development of evidence-based care in heart disease evaluated according to recommended therapies (SWEDEHEART) registry. The trial has a non-inferiority design, with a primary combined end point of all-cause death, non-fatal myocardial infarction, and unplanned revascularization at 12 months.

    Management of outpatients with stable coronary artery disease (CAD) is important in secondary prevention. The objective was to describe differences in the characteristics of CAD patients in Latvia compared with other countries. CLARIFY is an ongoing international, prospective, observational, longitudinal registry of outpatients with CAD. Data regarding treated outpatients with established CAD from the CLARIFY registry in Latvia (n=120) were compared with those from the rest of Central-Eastern Europe (CEE) (n=2888) and worldwide (n=33,163). Patients in Latvia had a larger waist circumference (101 [95-109] vs. 99 [91-106] in CEE, 96.5 [88-105]cm worldwide; P=0.023 and PLatvia did not differ significantly from that in CEE (P=0.422), but was higher than worldwide (28.8 [26.2-32.0] vs. worldwide 27.3 [24.8-30.3]kg/m(2), PLatvia (74.17% vs. 59.34% in CEE and 58.61% worldwide, P=0.001 and PLatvia vs. 89.75% in CEE and 87.64% worldwide, P=0.005 and P=0.001, respectively). Latvian CAD patients are well managed in terms of aspirin use and frequency of percutaneous coronary intervention. Control of obesity and high BP is poorer and needs further improvement.

    Full Text Available Statin therapy is regarded as an effective medication to reduce cardiovascular events in patients at higher risk for future incidence of coronary artery disease. However, very few studies have been conducted to examine its implementation in non-Western real-world practice. In this study, we sought to describe statin prescription patterns in relation to patient characteristics in a Japanese multicenter percutaneous coronary intervention (PCI registry as a foundation for quality improvement. We studied 15,024 patients that were prospectively enrolled in the Japan Cardiovascular Database-Keio interhospital Cardiovascular Study Registry from January 2009 to August 2014. The overall discharge statin non-prescription rate was 15.2%, without significant interhospital (MOR = 1.01 or annual differences (MOR = 1.13 observed. Hierarchical multivariable logistic regression analysis accounting for regional differences revealed that the presence of chronic kidney disease was associated with higher rates of statin non-prescription (OR 1.87, 95% confidence interval, 1.69-2.08, p value <0.001, and higher age (per 1-year increase showed a trend for prescription of low-intensity statin (OR 1.00, 95% confidence interval, 1.00-1.01, p value = 0.045 within the subset of PCI patients (N = 4,853 enrolled after the year 2011. Our study indicates that patients with chronic kidney disease and elderlies may be the primary targets for maximizing the beneficial effect of statin therapy in post PCI patients.

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    Full Text Available Background: Myocardial ischemia is one of several causes of prolonged QT dispersion. The aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina.Methods: We assessed the effects of full revascularization in patients with chronic stable angina and single-vessel disease who underwent percutaneous coronary intervention. Twelve-lead electrocardiograms were recorded before intervention and 24 hours subsequently. We measured parameters including QRS duration, QT and corrected QT durations, and JT and corrected JT duration in both electrocardiograms and compared the values.Results: There were significant differences between the mean QRS interval (0.086 ± 0.01sec vs. 0.082 ± 0.01 second; p value = 0.01, mean corrected QT dispersion (0.080 ± 0.04 sec vs. 0.068 ± 0.04 sec; p value = 0.001, and mean corrected JT dispersion (0.074 ± 0.04 sec vs. 0.063 ± 0.04 sec; p value = 0.001 before and after percutaneous coronary intervention. No significant differences were found between the other ECG parameters.Conclusion: Our data indicate that the shortening of corrected QT dispersion and corrected JT dispersion in patients undergoing percutaneous coronary intervention is prominent.

    AIMS: Collateral flow may influence long-term results after percutaneous coronary intervention (PCI) because of haemodynamic forces compete with the antegrade flow through the dilated lesion. The aim of the study was to assess the influence of recruitable collateral blood flow on restenosis......-derived collateral flow index (CFI) was determined as (P(w)-P(cvp))/(P(a)-P(cvp)), where P(w) represents coronary wedge pressure, P(cvp) central venous pressure, and P(a) mean aortic blood pressure. Both were measured during transient coronary occlusion by a balloon inflation of 30 s. Pre-interventional FFR (0.......65 +/- 0.20) correlated inversely with the CFI (0.18 +/- 0.11), r =- 0.356, P /=50% diameter stenosis) was seen in 29.1%.

    To implement secondary care electronic record linkage for patients hospitalised with suspected or known acute coronary syndrome (ACS) in a complex regional healthcare system and evaluate this e-Registry in terms of patterns of service delivery and 1-year outcomes. Existing electronic hospital records were linked to create episodes of care using (1) a patient administration system, (2) invasive cardiovascular procedure referrals and (3) a catheter laboratory record. Data were extracted for admissions (1 October 2013 - 30 September 2014) with ICD-10 diagnosis of angina (I200-I209), myocardial infarction (I210-I229), other ischaemic heart disease (I240-I249) or heart failure (I50), linked to other sources to develop a secondary care ACS e-registry and analysed within a Safe Haven. Episodes of care were categorised into care pathways and evaluated in terms of patient characteristics, as well as service delivery metrics and outcomes including mortality. 2327 patients had 2472 episodes of care. Diagnoses were hierarchically classified as STEMI (586, 25.2%), NSTEMI (1068, 45.9%), unspecified MI (146, 6.3%), unstable angina (527, 22.6%) for the first hospitalisation for each patient within the study period. Six care pathways were mapped. Percutaneous coronary intervention rate for STEMI was 80.2% and for NSTEMI 33.1%. Unadjusted all-cause mortality was 9.0% and 3.0% for STEMI and NSTEMI at 30 days, rising to 11.9% and 11.6% at 1 year. Analyses were validated by independent source data verification. The e-registry has enabled analysis of ACS hospitalisations in a complex healthcare system with implications for quality improvement and research.

  6. Coronary plaque morphology on multi-modality imagining and periprocedural myocardial infarction after percutaneous coronary intervention

    2016-06-01

    Full Text Available Percutaneous coronary intervention (PCI may be complicated by periprocedural myocardial infarction (PMI as manifested by elevated cardiac biomarkers such as creatine kinase (CK-MB or troponin T. The occurrence of PMI has been shown to be associated with worse short- and long-term clinical outcome. However, recent studies suggest that PMI defined by biomarker levels alone is a marker of atherosclerosis burden and procedural complexity but in most cases does not have independent prognostic significance. Diagnostic multi-modality imaging such as intravascular ultrasound, optical coherence tomography, coronary angioscopy, near-infrared spectroscopy, multidetector computed tomography, and magnetic resonance imaging can be used to closely investigate the atherosclerotic lesion in order to detect morphological markers of unstable and vulnerable plaques in the patients undergoing PCI. With the improvement of technical aspects of multimodality coronary imaging, clinical practice and research are increasingly shifting toward defining the clinical implication of plaque morphology and patients outcomes. There were numerous published data regarding the relationship between pre-PCI lesion subsets on multi-modality imaging and post-PCI biomarker levels. In this review, we discuss the relationship between coronary plaque morphology estimated by invasive or noninvasive coronary imaging and the occurrence of PMI. Furthermore, this review underlies that the value of the multimodality coronary imaging approach will become the gold standard for invasive or noninvasive prediction of PMI in clinical practice.

  7. Coronary collaterals and risk for restenosis after percutaneous coronary interventions: a meta-analysis

    2012-06-01

    Full Text Available Abstract Background The benefit of the coronary collateral circulation (natural bypass network on survival is well established. However, data derived from smaller studies indicates that coronary collaterals may increase the risk for restenosis after percutaneous coronary interventions. The purpose of this systematic review and meta-analysis of observational studies was to explore the impact of the collateral circulation on the risk for restenosis. Methods We searched the MEDLINE, EMBASE and ISI Web of Science databases (2001 to 15 July 2011. Random effects models were used to calculate summary risk ratios (RR for restenosis. The primary endpoint was angiographic restenosis > 50%. Results A total of 7 studies enrolling 1,425 subjects were integrated in this analysis. On average across studies, the presence of a good collateralization was predictive for restenosis (risk ratio (RR 1.40 (95% CI 1.09 to 1.80; P = 0.009. This risk ratio was consistent in the subgroup analyses where collateralization was assessed with intracoronary pressure measurements (RR 1.37 (95% CI 1.03 to 1.83; P = 0.038 versus visual assessment (RR 1.41 (95% CI 1.00 to 1.99; P = 0.049. For the subgroup of patients with stable coronary artery disease (CAD, the RR for restenosis with 'good collaterals' was 1.64 (95% CI 1.14 to 2.35 compared to 'poor collaterals' (P = 0.008. For patients with acute myocardial infarction, however, the RR for restenosis with 'good collateralization' was only 1.23 (95% CI 0.89 to 1.69; P = 0.212. Conclusions The risk of restenosis after percutaneous coronary intervention (PCI is increased in patients with good coronary collateralization. Assessment of the coronary collateral circulation before PCI may be useful for risk stratification and for the choice of antiproliferative measures (drug-eluting stent instead bare-metal stent, cilostazol.

    To evaluate (i) local coronary and systemic levels of microparticles (MP) in acute coronary syndrome (ACS) and stable angina pectoris (SAP) patients and (ii) their release after plaque disruption with percutaneous coronary intervention (PCI). MP are small vesicles originating from plasma membranes of cells after activation or apoptosis and are implicated in the pathogenesis of atherosclerosis. Neutrophils play a role in plaque destabilization and shed neutrophil-derived MP that have the potential to drive significant proinflammatory and thrombotic downstream effects. Eight ACS and eight SAP patients were included. Coronary sinus (CS) samples pre-intervention (CS1), 45 s following balloon angioplasty (CS2) and at 45 s intervals following stent deployment (CS3, CS4 and CS5), together with peripheral vein samples, pre- and post-PCI were analysed for neutrophil-derived (CD66b+), endothelial-derived (CD144+), platelet-derived (CD41a+), monocyte-derived (CD14+) and apoptotic (Annexin V+) MP. ELISA for interleukin (IL)-6, myeloperoxidase (MPO) and P-selectin was also performed. CD66b+ MP levels were similar in both groups pre-intervention. Post-PCI, CS levels rose significantly in ACS but not SAP patients (ACS area under the curve (AUC): 549 ± 83, SAP AUC: 24 ± 29, Pderived MP release post-PCI occurs in ACS compared with stable patients, likely to be reflective of plaque MP content in vulnerable lesions. © 2017 The Author(s).

    Acute myocardial infarction (AMI) is a leading cause of mortality in Asia. However, quantitative risk scores to predict mortality after AMI were developed without the participation of Asian countries. We evaluated the performance of the Global Registry of Acute Coronary Events (GRACE) in-hospital mortality risk score, directly and after recalibration, in a large Singaporean cohort representing 3 major Asian ethnicities. The GRACE cohort included 11,389 patients, predominantly of European descent, hospitalized for AMI or unstable angina from 2002 to 2003. The Singapore cohort included 10,100 Chinese, 3,005 Malay, and 2,046 Indian patients hospitalized for AMI from 2002 to 2005.Using the original GRACE score, predicted in-hospital mortality was 2.4% (Chinese), 2.0% (Malay), and 1.6% (Indian). However, observed in-hospital mortality was much greater at 9.8% (Chinese), 7.6% (Malay), and 6.4% (Indian). The c statistic for Chinese, Malays, and Indians was 0.86, 0.86, and 0.84, respectively, and the Hosmer-Lemeshow statistic was 250, 56, and 41, respectively. Recalibration of the GRACE score, using the mean-centered constants derived from the Singapore cohort, did not change the c statistic but substantially improved the Hosmer-Lemeshow statistic to 90, 24, and 18, respectively. The recalibrated GRACE score predicted in-hospital mortality as follows: 7.7% (Chinese), 6.0% (Malay), and 5.2% (Indian). In this large cohort of 3 major Asian ethnicities, the original GRACE score, derived from populations outside Asia, underestimated in-hospital mortality after AMI. Recalibration improved risk estimation substantially and may help adapt externally developed risk scores for local practice. Copyright © 2011 Mosby, Inc. All rights reserved.

    Gender-related differences in mortality of acute coronary syndrome (ACS) have been reported. The extent and causes of these differences in the Middle-East are poorly understood. We studied to what extent difference in outcome, specifically 1-year mortality are attributable to demographic, baseline clinical differences at presentation, and management differences between female and male patients. Baseline characteristics, treatment patterns, and 1-year mortality of 7390 ACS patients in 65 hospitals in 6 Arabian Gulf countries were evaluated during 2008-2009, as part of the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2). Women were older (61.3±11.8 vs. 55.6±12.4; Pmanagement differences contributed to a worse outcome in women. Together these variables explained almost all mortality disparities. Differences between genders in mortality appeared to be largely explained by differences in prognostic variables and management patterns. However, the origin of the latter differences need further study.

    Traditionally, patients are kept nil-per-os/nil-by-mouth (NPO/NBM) prior to invasive cardiac procedures, yet there exists neither evidence nor clear guidance about the benefits of this practice. To demonstrate that percutaneous cardiac catheterisation does not require prior fasting. The data source is a retrospective analysis of data registry of consecutive patients who underwent percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) and stable angina at two district general hospitals in the UK with no on-site cardiac surgery services. A total of 1916 PCI procedures were performed over a 3-year period. None of the patients were kept NPO/NBM prior to their coronary procedures. The mean age was 67±16 years. 1349 (70%) were men; 38.5% (738/1916) had chronic stable angina, while the rest had ACS. 21% (398/1916) were diabetics while 53% (1017/1916) were hypertensive. PCI was technically successful in 95% (1821/1916) patients. 88.5% (1697/1916) had transradial approach. 77% (570/738) of elective PCI patients were discharged within 6 h postprocedure. No patients required emergency endotracheal intubation and there were no occurrences of intraprocedural or postprocedural aspiration pneumonia. Our observational study demonstrates that patients undergoing PCI do not need to be fasted prior to their procedures.

    Improvements in the treatment of coronary artery disease mean that an increasing number of patients survive acute cardiovascular events and live as outpatients with or without anginal symptoms. To determine the characteristics and management of contemporary outpatients with stable coronary artery disease in Western Europe, and to compare France with the other Western European countries. CLARIFY (prospeCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease) is an international, prospective, observational, longitudinal study. Between November 2009 and July 2010, 32,954 adult outpatients with stable coronary artery disease (defined as a history of documented myocardial infarction [of >3 months], prior coronary revascularization, chest pain with myocardial ischaemia, or coronary stenosis of>50% proven by angiography) were enrolled in 45 countries. The demographics and management of CLARIFY patients enrolled in France were compared with those enrolled in other Western European countries (Austria, Belgium, Denmark, Germany, Greece, Ireland, Italy, Netherlands, Portugal, Spain, Switzerland and the UK). Of the 14,726 patients enrolled in Western Europe (mean age 66.2 [10.2] years; 79.6% male), 2432 (16.5%) were from France. The use of aspirin was lower in France than in other Western European countries (74.5% vs. 86.9%, respectively), whereas use of thienopyridines (48.5% vs. 21.7%), oral anticoagulants (12.3% vs. 9.0%) and lipid-lowering drugs (95.8% vs. 92.5%) was higher. Beta-blockers were used in 73% of both groups. Angina was less prevalent in France (6.3% vs. 15.5%) and French patients showed higher levels of physical activity than their counterparts in Western Europe. The management of patients with stable CAD in France appears favourable, with good adherence to guideline-based therapies, but there remains room for improvement in terms of symptom and risk factor control.

    Objective: To discuss the incidence and clinical predictors of radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease. Methods: A total of 1020 patients, who underwent transradial coronary procedures for coronary heart disease during the period of May 2007 Jan 2010 in authors' hospital, were enrolled in this study. All clinical information and medication were recorded in detail. Arteriography via radial artery was performed in all patients. The diameter of the radial artery as well as the arterial anatomy, including arterial variations, were determined and observed, which was follow by coronary angiography or percutaneous coronary intervention. Multivariate Logistic regression analysis was adopted to evaluate the variables, such as clinical parameters, angiographic characteristics of the radial artery and procedure-related factors, in predicting the occurrence of radial artery spasm. Results: Radial artery spasm occurred in 209 (20.5%) patients. Multivariate Logistic regression analysis showed that the following eight factors were independently associated with the occurrence of radial artery spasm. These factors were as follows: female gender (OR=2.8, 95% CI 2.5-5.8; P=0.001), age (OR=0.68, 95% CI 0.60-0.92; P=0.003), smoking (OR=2.3, 95% CI 1.8-4.1; P=0.026), moderate-to-severe pain of forearm during radial artery cannulation (OR=3.0, 95% CI 2.3-4.8; P=0.006), radial artery anatomical abnormalities (OR=4.7, 95% CI 3.6-7.2; P=0.002), the ratio of radial artery diameter to patient's height (RAH) (OR=5.2, 95% CI 3.7-8.1; P=0.012), the ratio of radial artery diameter to outer diameter of the sheath (RAOD) (OR=5.8, 95% CI 4.2-6.9; P=0.006) and the number of catheter exchange (OR=2.3, 95% CI 1.4-4.3; P=0.038).

    In this article we have outlined the current rationale and role of invasive management in ACS. For the majority of patients with ACS, who are either at high risk or unstable, invasive management is a critical element in breaking the sequence of recurrent ischemia leading to early cardiac events (Fig. 11). Secular trends in the care of cardiovascular patients predict even more sophisticated, invasive methods of treating coronary occlusion in the future. A futurist's view on this subject may envision the following type of scenario. A patient with prior CAD experiences persistent chest pain and notifies the emergency medical system. The paramedics arrive, and perform a rapid fingerstick cardiac biomarker panel and ECG. The results are interpreted by an emergency physician via a telecommunication system, and the patient is determined to be at high risk. He or she is triaged to a center capable of angioplasty and bypass surgery. On the way to the hospital, the patient is treated with aspirin, IV heparin, and an IV glycoprotein IIb/IIIa inhibitor. The patient undergoes triage angiography within 1 hour of hospital arrival, culprit lesion(s) are identified, and a revascularization plan is made--setting a critical pathway that is definitive. This vision is not far off on the horizon. We anticipate additional clinical trial results will help form the decision points in this optimal treatment scenario, which for a large proportion of patients will involve invasive management.

Changes seen in revascularization techniques have been numerous. The rapid evolution of evidence-based revascularization procedures has occurred as a result of many pivotal large randomized clinical trials. Objective: This review compares and contrasts outcomes from two coronary revascularization techniques, coronary artery bypass grafting (CABG and PCI, with particular reference to the landmark trials that inform practice guidelines. Methods: We undertook a comprehensive review of published literature addressing trials in this field performed to address current knowledge both in the predrug-eluting stent and postdrug-eluting stent era. Results and discussion: Surgical and percutaneous revascularization strategies have different strengths and weaknesses, and neither strategy is superior in all patients, clinical presentations, or anatomical subgroups. Current data support the use of percutaneous intervention in ST elevation myocardial infarction and in single-vessel disease. In noncomplex multivessel disease and isolated left main stem PCI, the data support non-inferiority of PCI compared to CABG as reflected in the 2014 European Society of Cardiology guidelines. Landmark revascularization trials of multivessel disease comparing CABG to PCI found no survival benefit to CABG over PCI, except in patients with complex disease. In these trials, revascularization drove differences in primary endpoints and in all but the

    A large-lumen guiding catheter is often used for complex percutaneous coronary intervention-particularly when a final kissing-balloon or 2-stent technique is required. However, catheter insertion is sometimes restricted by diseased vascular access sites or a tortuous vascular route.We report 2 cases in which a unique double guiding catheter technique was used to create a lumen of sufficient size for complex percutaneous coronary intervention. In each patient, two 6F guiding catheters were used concurrently to engage the ostium of 1 target vessel. In 1 patient, these catheters were used for the delivery of 2 balloons to complete kissing-balloon dilation after single-stent placement. In the other patient, the catheters were used to deliver 2 stents sequentially to their respective target lesions. The stents were then deployed simultaneously as kissing stents, followed by high-pressure kissing-balloon postdilation.

    Background/purpose: Coronary in-stent restenosis (ISR) is a clinical problem for which a satisfactory solution has not been found yet. Bioabsorbable drug eluting vascular scaffolds (BVSs) provide transient vessel scaffolding combined with prolonged drug delivery capability. The aim of this study was to investigate the safety of BVS for the treatment of coronary ISR. Methods/materials: Between January 2013 and June 2013, 27 patients (31 lesions), presenting with either stable or unstable angina due to coronary ISR, were enrolled in a single arm, prospective, open label registry. Primary end point was the occurrence of target vessel revascularization (TVR) at 12 months. Secondary end point was the composite of death, myocardial infarction and TVR at 12 months. Results: A diffuse ISR pattern was present in 70% of the lesions; mean lesion length was 34.6 ± 15. BVS was successfully implanted in all patients with no in hospital MACE. At twelve months of follow up, MACE rate was 18.5%. One patient died for non-cardiac reason, one patient died due to a possible stent thrombosis and TVR was necessary in 3 patients (11.1%). Conclusions: Our data suggest that BVS is safe and technically feasible for treatment of long and diffuse coronary ISR. These data could be considered hypothesis generator for a randomized clinical trial. - Highlights: • A safe therapeutic option for the treatment of diffuse ISR; • Technically feasible; • Associated to a low rate of restenosis recurrence at nine month.

    To evaluate the efficacy of a program of lifestyle change through psychological intervention, combined with pharmacological therapy, for coronary risk reduction in uncontrolled hypertensive patients with overweight and dyslipidemia over 11 months of follow-up. A randomized controlled trial with 74 patients assigned to three different treatment programs. One group (CT) only received conventional pharmacological treatment. Another group (OG) received pharmacological treatment and participated in a guidance program to control cardiovascular risk factors. A third group (LSPI) received pharmacological treatment and participated in a brief psychological intervention program for reduction of estresse levels and changing of eating behavior. The main measure was the Framingham risk index. CT patients presented an average reduction of 18% (p = 0.001) in coronary risk; OG patients elevated the risk by 0.8% (NS) and the LSPI group showed an average reduction of 27% on the Framingham risk index (p = 0.001). Pharmacological treatment combined with psychological intervention for reduction of estresse level and changing of eating behavior resulted in additional benefits in coronary risk reduction.

    This study aimed to assess the effects of a psychological intervention programme on the mental stress, coping style and cortisol and IL-2 levels of patients undergoing percutaneous coronary intervention (PCI). A total of sixty cardiovascular patients scheduled for PCI with clear anxiety and depression screened by the Hospital Anxiety and Depression Scale were randomly divided into an experimental (n = 30) and control (n = 30) group. The participants in the experimental group received cognitive therapy, relaxation therapy and emotional support. Self-reported questionnaires, including the Self-Report Symptom Checklist (SCL-90) and the Medical Coping Mode Questionnaire (MCMQ), and levels of IL-2 and cortisol were collected at baseline and the day before discharge. Compared with the controls, patients in the intervention group had a better mental state and coping style (confrontation), higher levels of IL-2 and lower levels of cortisol (all Pcoping styles, increased levels of IL-2, and decreased cortisol levels in patients undergoing PCI.

    To determine the potential clinical impact of OCT (Optical Coherence Tomography) during primary percutaneous coronary intervention in patients presenting with ACS (Acute Coronary Syndrome). FORMIDABLE is a multicentre retrospective registry enrolling all patients presenting with ACS and treated with an OCT-guided approach, while the USZ registry enrolled patients treated with a standard angiography guided approach. Multivariate adjustment was performed via a propensity score matching. The number stents useds was the primary outcome, while the incidence of MACE (a composite of death, myocardial infarction, target vessel revascularization, and stent thrombosis) was the secondary endpoint. A total of 285 patients OCT-guided and 1,547 angiography guided patients were enrolled, resulting in 270 for each cohort after propensity score with matching. Two stents were used in 12% versus 34%; 3 stents in 8% versus 38% of the patients (P < 0.001). After a follow up of 700 days (450-890), there was no difference in myocardial infarction (6% vs. 6%, P = 0.86), while MACE (11% vs. 16%, P = 0.06), target vessel revascularization (2% vs. 4%, P = 0.15) and stent thrombosis rates (0% vs. 2.7%, P = 0.26) were numerically lower for the OCT-guided cohort but none of these endpoints did reach statistical significance. An OCT-guided approach reduced the number of stents used, number of patients treated with more than one stent, while there was no statistically significant difference in clinical endpoints while most of them were numerically lower, including stent thrombosis rates. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The publication of the NOBLE and EXCEL trials, with seemingly conflicting results, brought into question whether percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is better for low-risk patients with left main coronary artery stenosis (LMCAS). This review appraises the methods and results of NOBLE and EXCEL, contextualizes them within the literature, and determines how they may affect clinical practice. We appraised the trials and describe differences in methodology and results. NOBLE recruited primarily isolated LMCAS, and found that CABG was superior to PCI. EXCEL's population included patients LMCAS in the context of multivessel CAD, and found PCI and CABG were comparable. Both trials enrolled young patients with few comorbidities, and there was more protocol-mandated consistency in the procedural techniques and medical therapy of patients receiving PCI. The generalizability of these trials is limited by the use of young, healthy patients at highly skilled centres that rarely reflect typical clinical practice. If these studies are to maintain relevance, trialists must address the lack of protocolization of surgical interventions and inconsistent medical therapies. Unfortunately, the limitations of NOBLE and EXCEL mean that we are no closer to answering the question of what is the optimal treatment for patients with LMCAS.

    The aim of this study was to report on the midterm outcomes of patients undergoing percutaneous coronary intervention with bioresorbable vascular scaffolds (BVS) for the treatment of acute coronary syndromes (ACS) and compare with those of patients with stable coronary artery disease (sCAD). One thousand four hundred and seventy-seven (1,477) patients underwent implantation of one or more BVS (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) at 11 European centres and were included in the GHOST-EU registry. Admissions comprised 47.1% of the patients (951 BVS) with ACS, and 52.8% (1,274 BVS) with sCAD. During a median follow-up of 384 (359-460) days, patient-oriented endpoints (PoCE), including all-cause death, any infarction, any revascularisation, were recorded in 271 patients (12-month incidence in ACS patients: 18.5% vs. 11.6% in the sCAD group, psCAD group, 6.4% in the ACS group; p=0.052). The 12-month incidence of definite scaffold thrombosis was 2.6% in ACS patients and 0.8% in XIENCE patients (p=0.006). In multivariate analysis, ACS was a predictor of DoCE (HR: 2.26 [1.34-3.81], p=0.002), PoCE (HR: 1.71 [1.13-2.58], p=0.011), and stent thrombosis (HR: 2.51 [1.13-5.60], p=0.025). In contrast, the incidence of target lesion revascularisation was not different between groups. There was no difference in the incidence of any of these endpoints among the different clinical presentations (unstable angina, non-ST-elevation infarction and ST-elevation infarction). PoCE, DoCE and scaffold thromboses were more frequent in ACS patients, without any difference among different forms of ACS.

    Percutaneous coronary intervention-induced myocardial infarction (PMI) has prognostic significance. Identifying patients at high risk for PMI is desirable as it may alter strategy and facilitate early preventative therapy. We therefore sought to establish whether preprocedural demographic, interventional (plaque characteristics and coronary microcirculatory function), and inflammatory, endothelial damage, and platelet-derived biomarker data could predict the risk of PMI. We performed target vessel pressure wire to assess fractional flow reserve, index of microcirculatory resistance (IMR) and coronary flow reserve, plaque characterization by virtual histology intravascular ultrasound, and assayed peripheral biomarkers before uncomplicated PCI in 88 patients. We then analyzed post-PCI cardiac troponin level to adjudicate PMI based on the third universal definition of myocardial infarction. Overall incidence of PMI was 27%. Women [10/15 (66%) vs. 14/73 (19%), PPMI. Preprocedural coronary flow reserve was lower in individuals with a subsequent PMI (1.8±1.2 vs. 2.1±1.3. P=0.03), and patients with higher pre-PCI IMR were more likely to sustain PMI [IMR>22: 10/23 (44%) vs. ≤22: 14/65 (22%), P=0.04], although neither was predictive after multivariate analysis. Plaque characterization by virtual histology intravascular ultrasound did not discriminate those at risk of PMI. However, peripheral venous interleukin (IL)-18 and IL-8 levels were independently negatively and positively associated with PMI, respectively. Women and those with low BMI, particularly when associated with high IL-8 and low IL-18 levels, appear to be at increased risk of PMI.

    Full Text Available Introduction: Coronary artery disease (CAD is as a leading cause of death and disability all around the world. Multiple risk factors have a role in the development and progression of coronary heart disease (CHD. It is necessary to control risk factors, to achieve optimal results of treatment. The aim of present study was to evaluate the persistence of cardiovascular risk factors in patients with CADs after percutaneous cardiac interventions. Methods: In an analytical-descriptive study, 150 patient with CAD and percutaneous coronary intervention (PCI were performed for them, and referred to Cardiology Clinic of Shahid Madani Hospital of Tabriz University of Medical Sciences, Tabriz, Iran, from September 2013 to September 2015, were studied. The persistence of coronary risk factors, 12-24 months after performing PCI, was evaluated. Results: The mean age of patients at time of PCI performing was 57.90 ± 12.26 years. 72.7% of patients were male and 27.3% were female and male to female ratio was 1 to 0.37. Dyslipidemia in 52.0% of patients, hypertension in 51.3% patients, and diabetes mellitus (DM in 41.3% patients were the most common underlying comorbidities. In both before and after doing PCI, 26.7% were a smoker, and smoking rates after doing PCI also showed no significant change (P = 0.055, and also there were no significant changes in the physical activity of patients compared before and after performing PCI. Conclusion: Based on the findings of the present study, dyslipidemia, hypertension, and DM, was the most frequent underlying diseases in patients with CAD respectively. Risk factors such as smoking, and lack of exercise, had no significant changes after performing PCI.

Data within different Asian subpopulations is scarce. We aim to explore the differences in clinical profile and outcome between Chinese, Malay and Indian Asian patients who undergo PCI for coronary artery disease (CAD. Methods A prospective registry of consecutive patients undergoing PCI from January 2002 to December 2007 at a tertiary care center was analyzed. Primary endpoint was major adverse cardiovascular events (MACE of myocardial infarction (MI, repeat revascularization and all-cause death at six months. Results 7889 patients underwent PCI; 7544 (96% patients completed follow-up and were included in the analysis (79% males with mean age of 59 years ± 11. There were 5130 (68% Chinese, 1056 (14% Malays and 1001 (13.3% Indian patients. The remaining 357 (4.7% patients from other minority ethnic groups were excluded from the analysis.

    We report the 1-year outcomes of real-world patients with severely calcified coronary arteries who underwent orbital atherectomy. Percutaneous coronary intervention of heavily calcified lesions is technically challenging and associated with worse clinical outcomes. Modification of severely calcified coronary lesions with orbital atherectomy facilitates stent delivery and expansion. Although we previously reported the safety of orbital atherectomy at 30 days in all comers with severely calcified coronary lesions, including patients who were excluded from the ORBIT II trial, longer-term follow-up is unknown. We retrospectively analyzed 458 all-comer patients who underwent orbital atherectomy followed by stenting from October 2013 to December 2015 at three centers. The primary endpoint was the 1-year major adverse cardiac and cerebrovascular event (MACCE) rate, defined as the composite of death, myocardial infarction, target-vessel revascularization, and stroke. One-year data were available for 453/457 patients (98.9%). At 1-year follow-up, the MACCE rate was 12.6%, death rate was 4.0%, myocardial infarction rate was 1.8%, target-vessel revascularization rate was 7.5%, stroke rate was 1.3%, and stent thrombosis rate was 1.3%. Orbital atherectomy is a valuable option for the treatment of severely calcified coronary arteries, including patients with very complex coronary anatomy and severe underlying comorbid conditions. Orbital atherectomy provided acceptable outcomes at 1 year and compared favorably to historical controls. A randomized trial with longer follow-up is needed to determine the optimal treatment strategy for patients with severely calcified coronary lesions.

    The APPOSITION III registry evaluated the feasibility and performance of the STENTYS self-apposing stent in an ST-segment elevation myocardial infarction (STEMI) population. This novel self-apposing stent device lowers stent strut malapposition rates and therefore carries the potential to prevent stent undersizing during primary percutaneous coronary intervention (PCI) in STEMI patients. To date, no long-term data are available using this device in the setting of STEMI. We aimed to evaluate the long-term clinical outcomes of the APPOSITION III registry. This was an international, prospective, multicentre post-marketing registry. The study population consisted of 965 STEMI patients. The primary endpoint, major adverse cardiac events (MACE), was defined as the composite of cardiac death, recurrent target vessel myocardial infarction (TV-MI), and clinically driven target lesion revascularisation (CD-TLR). At two years, MACE occurred in 11.2%, cardiac death occurred in 2.3%, TV-MI occurred in 2.3% and CD-TLR in 9.2% of patients. The two-year definite stent thrombosis (ST) rate was 3.3%. Incremental event rates between one- and two-year follow-up were 1.0% for TV-MI, 1.8% for CD-TLR, and 0.5% for definite ST. Post-dilation resulted in significantly reduced CD-TLR and ST rates at 30-day landmark analyses. Results were equivalent between the BMS and PES STENTYS subgroups. This registry revealed low rates of adverse events at two-year follow-up, with an incremental ST rate as low as 0.5% in the second year, demonstrating that the self-apposing technique is feasible in STEMI patients on long-term follow-up while using post-dilatation.

    Full Text Available BACKGROUND There is a paucity of data among octogenarians undergoing coronary interventions in India. These patients have generally been excluded from randomised trials. As a result, there are no evidence-based guidelines regarding PCI in very elderly. The aim of this study is to describe the epidemiology, clinical characteristics, management and the outcomes of patients over the age of 80 years who were undergoing coronary interventions. MATERIALS AND METHODS We evaluated the outcomes of all patients over the age of 80 years admitted in KIMS, Hubli, during the year 2015-16 undergoing coronary interventions including coronary angiography and Percutaneous Coronary Interventions (PCI. RESULTS We identified 36 octogenarians (67% men, 33% women; Mean Age of 84.2 ± SD 3.6 years. 52.3 percent of patients presented with an acute coronary syndrome treated either with thrombolysis or medical stabilisation followed by coronary angiography. One patient in the study was taken for primary Percutaneous Coronary Interventions (PCI. Mean duration of hospitalisation was 6.69 ± 6.8 days. Overall, the frequency of in-hospital death was n=2 (5.5% and both the patients died while awaiting CABG. CONCLUSION Our study shows that coronary interventions are safe and effective and are not associated with any major complications, which are specific to this subset. Thus, advanced age should not be considered a contraindication for coronary interventions when clear indications are present.

    With new developments in percutaneous coronary intervention (PCI), such as the introduction of bioresorbable scaffolds (BRS), percutaneous treatment of coronary artery diseases has entered a new era. Without metallic remnants, BRSs appear able to overcome several limitations of the existing metallic stents and provide a physiologic treatment of coronary artery pathology. BRS have different mechanical properties compared to the traditional metallic stents that should be taken into account during their implantation. Lesion selection, device sizing and satisfied pre-dilatation should be implemented prudently. Although intravascular imaging is not mandatory for the implantation of BRSs it may have a value in optimizing device deployment assess final results and reduce the risk of device related adverse events such as re-stenosis, or scaffold thrombosis. This review aims to reveal the crucial points about the methods of optimization in each steps of BRS implantation. Expert commentary: The target lesions for BRS should be selected meticulously. Pre-dilatation, post-dilatation and intra-vascular imaging techniques should be implemented appropriately to avoid undesirable events after scaffold implantation.

    We describe the case of a 78-year-old patient, admitted to our hospital with an acute coronary syndrome. Coronary angiography showed multivessel coronary artery disease and an anomalous coronary vessel branching from the right coronary artery. After successful percutaneous revascularization and discharge, the anomalous vessel was diagnosed by contrast enhanced 64-multidetector computed tomography as a coronary-to-bronchial fistula. Since the patient was asymptomatic, conservative treatment was selected.

    Although about half of patients with spontaneous coronary artery dissection (SCAD) face ongoing necrosis, conservative therapy is recommended due to a high complication rate in angiography-guided percutaneous coronary intervention (PCI). The aim of this study was to investigate clinical outcomes of SCAD treated by optical coherence tomography (OCT)-guided PCI. This study consisted of consecutive 306 patients with acute coronary syndrome (ACS) who underwent OCT-guided PCI. Based on the culprit lesion morphology by OCT, patients were assigned to four groups: a SCAD group, a plaque rupture (PR) group, a calcified nodule (CN) group, and an undetermined etiology (UE) group. Successful PCI was defined as thrombolysis in myocardial infarction flow grade 3 in final angiography without any complications. Primary endpoint was defined as occurrence rate of major adverse cardiac events (MACE) including cardiac death, myocardial infarction, and unstable angina pectoris. OCT revealed 12 SCADs, 149 PRs, 16 CNs, and 129 UEs, respectively. No significant difference was observed in the success rate of PCI (SCAD 91.7%, PR 85.2%, CN 81.2%, UE 86.8%, p=0.88), while wire repositioning was needed in 2 SCAD cases (pSCAD were favorable, as well as those for other ACS etiologies. OCT-guided PCI could become a therapeutic option for SCAD compromised with ongoing necrosis. Copyright © 2017 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    We performed a meta-analysis of the studies comparing the efficacy and safety of coronary artery bypass surgery against percutaneous coronary intervention with drug-eluting stents (PCI-DES) in patients with isolated LAD disease. Because of the limited randomized trial data, the optimal revascularization strategy for patients with isolated LAD disease remains uncertain. Using MEDLINE and EMBASE to source data, 11 studies (3 randomized trials and 8 cohort studies) including 5,044 participants were identified. No significant difference in mortality between PCI-DES and coronary artery bypass surgery (CABG; 111 of 2,122 [5.2%] and 120 of 2,574 [4.7%]; relative risk [RR] 1.23; 95% confidence interval [CI] 0.90 to 1.69) was detected. For MACE, PCI-DES was associated with significant increase in adverse events (RR 1.41; 95% CI 1.03 to 1.93, 8 studies, 4,230 participants). There were no significant differences in the risk of myocardial infarction (RR 0.86; 95% CI 0.58 to 1.26) or stroke (RR 2.36; 95% CI 0.54 to 10.43) between the 2 groups. There were 239 target vessel revascularization (TVR) events among 2,237 participants in the PCI-DES group (10.7%) and 145 TVR events among 2,793 participants in the CABG group (5.2%) with a significant increased risk of TVR in the PCI group (RR 2.52; 95% CI 1.69 to 3.77, 5,030 participants) compared with CABG. In conclusion, for patients with isolated disease of the LAD, meta-analysis of the available data suggests revascularization with a PCI-DES strategy offers similar mortality, MI, and stroke rates to CABG at the expense of increased TVR. Much of the data are derived from registries using first-generation DES, and further randomized trials with more contemporary platforms are needed. Copyright © 2016 Elsevier Inc.

    Full Text Available Background: Right Ventricular (RV dysfunction has been introduced as a predictor of mortality in acute myocardial infarction. Objectives: This study aimed to investigate the effect of right coronary revascularization on systolic and diastolic RV dysfunction. Patients and Methods: This study was conducted on unstable angina patients who were candidate for elective Percutaneous Revascularization Intervention (PCI on the right coronary artery. The participants were initially evaluated by transthoracic echocardiography and tissue Doppler imaging prior to PCI and the RV function parameters were assessed. Echocardiography was repeated two months after PCI and the results were compared with baseline. Paired t-test was used to compare the pre- and post-procedural measurements. Besides, Pearson’s correlation was used to find out the linear association between the RV function parameters and Left Ventricular Ejection Fraction (LVEF. P value < 0.05 was considered as statistically significant. Results: This study was conducted on 30 patients (mean age = 60.00 ± 8.44 years; 24 [80%] males. In the pre-procedural echocardiography, 15 patients (50% had normal RV function, 14 patients (46.7% had grade-1 RV dysfunction, and only 1 patient (3.3% had grade-2 RV dysfunction. Following PCI, however, all the patients had normal systolic and diastolic RV functions. Comparison of echocardiographic RV function parameters showed an improvement in both systolic and diastolic functional parameters of the RV. Nonetheless, no significant correlation was observed between these parameters and Left Ventricular (LV function. Conclusions:: A significant improvement was found in RV function, but not LV function, after right coronary PCI. Revascularization of the right coronary artery may be beneficial for the patients who suffer from RV failure due to ischemia

    We sought to determine the frequency of use and association between prasugrel and outcomes in acute coronary syndrome patients undergoing percutaneous coronary intervention (PCI) in clinical practice. PROMETHEUS was a multicenter observational registry of acute coronary syndrome patients undergoing PCI from 8 centers in the United States that maintained a prospective PCI registry for patient outcomes. The primary end points were major adverse cardiovascular events at 90days, a composite of all-cause death, nonfatal myocardial infarction, stroke, or unplanned revascularization. Major bleeding was defined as any bleeding requiring hospitalization or blood transfusion. Hazard ratios (HRs) were generated using multivariable Cox regression and stratified by the propensity to treat with prasugrel. Of 19,914 patients (mean age 64.4years, 32% female), 4,058 received prasugrel (20%) and 15,856 received clopidogrel (80%). Prasugrel-treated patients were younger with fewer comorbid risk factors compared with their counterparts receiving clopidogrel. At 90days, there was a significant association between prasugrel use and lower major adverse cardiovascular event (5.7% vs 9.6%, HR 0.58, 95% CI 0.50-0.67, P<.0001) and bleeding (1.9% vs 2.9%, HR 0.65, 95% CI 0.51-0.83, P<.001). After propensity stratification, associations were attenuated and no longer significant for either outcome. Results remained consistent using different approaches to adjusting for potential confounders. In contemporary clinical practice, patients receiving prasugrel tend to have a lower-risk profile compared with those receiving clopidogrel. The lower ischemic and bleeding events associated with prasugrel use were no longer evident after accounting for these baseline differences. Copyright © 2017 Elsevier Inc. All rights reserved.

    Medical visualization is a rapidly developing field with many application areas spanning from visualization of anatomy to surgery planning, to understanding of disease processes. With increasing computer speed, medical visualization is becoming more real-time. In this paper, we present a novel application of real-time three-dimensional visualization of coronary arteries during catheter interventions that combines image information from two complementary sources: biplane x-ray contrast angiography and intravascular ultrasound (IVUS). After identification of the three-dimensional characteristics of the intravascular ultrasound pullback sequence, vessel geometry and vessel wall images are combined into a single visualization using semi-automated analysis of a corresponding pair of biplane angiography images. Visualization data are represented using the Virtual Reality Modeling Language (VRML), the code for which is automatically generated by our angiography/IVUS image processing and analysis software system. Selection of the VRML approach facilitates real-time 3-D visualization with an ability of over-the-network image processing and dissemination of results. The visualization specifics are easily modifiable in near real time to consider the immediate requirements of the end-user, the cardiologist who performs the coronary intervention.

    The aim of this report is to analyse trends in Italian cathlab activity between 2010 and 2015. Data were obtained from the national database of the Italian Society of Interventional Cardiology (GISE), which includes 97% of Italian cardiac catheterisation laboratories. The number of percutaneous coronary interventions (PCI) has remained relatively stable in the past five years. We have observed a significant increase in the number of primary PCI (pPCI) from 471.5 to 557.5 per million inhabitants with a consequent reduction of rescue primary PCI/fibrinolysis. One of the possible explanations for this might be the extensive networking for primary PCI and the adoption of Stent for Life initiatives in five regions. There has been a notably increased use of drug-eluting stents and, despite the fact that the introduction of bioabsorbable vascular scaffolds is recent, there is a slight, progressively positive trend. Invasive physiologic evaluation of coronary stenosis has markedly increased. Radial artery access has become the default option for PCI and for pPCI. In the last five years, TAVI procedures have doubled in number, while MitraClip and mitral repair procedures have shown a fivefold increase. Left atrial appendage (LAA) occlusion procedures have more than doubled in four years.

    The objective of this study was to report long-term results of early endovascular aortic aneurysm repair after percutaneous coronary intervention (PCI). This was a retrospective analysis of all patients presenting with abdominal aortic aneurysm and coronary artery disease treated during the same hospitalization by endovascular aortic aneurysm repair performed soon after PCI. Primary outcomes were perioperative mortality, perioperative complications, survival after treatment, and freedom from reintervention. A total of 20 patients were included, and all completed both procedures. No deaths or abdominal aortic aneurysm ruptures occurred between the PCI and the aortic intervention. Perioperative mortality was 5% as one patient died of mesenteric ischemia after endovascular aneurysm repair. Major cardiovascular vascular complications occurred in four patients (20%) and included non-ST-segment elevation myocardial infarction (one) and access vessel complication (three). Mean follow-up was 94 (range, 1-164; standard deviation, 47) months. Estimated survival at 1 year, 2 years, 5 years, and 10 years was 90%, 90%, 90%, and 60%, respectively. A reoperation was required in six patients. Estimated freedom from reintervention at 1 year, 2 years, 5 years, and 10 years was 83%, 83%, 78%, and 72%, respectively. Our study indicates that early endovascular aneurysm repair performed within a week after PCI may be a reasonable approach in patients with large or symptomatic aneurysms.

    Hypertension affects one billion people worldwide and is an independent risk factor for death after acute coronary syndrome (ACS). The aim of this study was to examine the prevalence and medical treatment of hypertension among 1,301 ACS patients enrolled into the Chinese registry of acute coronary events (CRACE) trial. Analyses were performed by gender, with both genders combined and according to international practice. Multivariable models identified factors associated with use of different classes of antihypertensive medication, and examined the correlation between hypertension and gender with mortality. The use of angiotensin‑converting enzyme inhibitors (ACEI), β-blockers, calcium channel blockers (CCBs) and diuretics increased in both genders during management of presenting ACS. Hypertensive men were more likely to have been receiving β-blockers when they were discharged (77.2%) than women (69.2%). Hypertensive women were more likely to have received diuretics when they were discharged (28.4%) than men (22%). ACEI use increased by ~60% (absolute increase) in both women and men as a result of ACS treatment, but remained similar between the genders, and the same phenomenon was observed in the use of CCBs. Moreover, hypertensive women were less likely to receive evidence‑based medication to treat their acute coronary event than men (for women and men, respectively: β-blocker, 69.2 vs. 77.2%; ACEI, 85.8 vs. 87.5%). Hypertension is more prevalent in women than in men with ACS, and its medical management varies with gender, but it has a similar association with mortality in both genders. Opportunities exist to improve medical therapy and outcomes for women with hypertension.

    To clarify the effect of single-session multivessel percutaneous coronary intervention (PCI) strategy relative to the staged multivessel strategy on clinical outcomes in patients with stable coronary artery disease (CAD) or non-ST-elevation acute coronary syndrome. In the Coronary REvascularisation Demonstrating Outcome Study in Kyoto PCI/coronary artery bypass grafting registry cohort-2, there were 2018 patients who underwent elective multivessel PCI. Primary outcome measure was composite of all-cause death, myocardial infarction and stroke at 5-year follow-up. Single-session multivessel PCI and staged multivessel PCI were performed in 707 patients (35.0%) and 1311 patients (65.0%), respectively. The cumulative 5-year incidence of and adjusted risk for the primary outcome measure were not significantly different between the single-session and staged groups (26.7% vs 23.0%, p=0.45; HR 0.91, 95% CI 0.72 to 1.16, p=0.47). The 30-day incidence of all-cause death was significantly higher in the single-session group than in the staged group (1.1% vs 0.2%, p=0.009). However, the causes of death in 11 patients who died within 30 days were generally not related to the procedural complications, but related to the serious clinical status before PCI. For the subgroup analyses including age, gender, extent of CAD, severe chronic kidney disease and heart failure, there was no significant interaction between the subgroup factors and the effect of the single-session strategy relative to the staged strategy for the primary outcome measure. The single-session multivessel PCI strategy was associated with at least comparable 5-year clinical outcomes compared with the staged multivessel PCI, although the prevalence of the single-session strategy was low in the present study. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Background Although psychological interventions are recommended for the management of coronary heart disease (CHD), there remains considerable uncertainty regarding their effectiveness. Design Systematic review and meta-analysis of randomised controlled trials (RCTs) of psychological interventions for CHD. Methods The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL and PsycINFO were searched to April 2016. Retrieved papers, systematic reviews and trial registries were hand-searched. We included RCTs with at least 6 months of follow-up, comparing the direct effects of psychological interventions to usual care for patients following myocardial infarction or revascularisation or with a diagnosis of angina pectoris or CHD defined by angiography. Two authors screened titles for inclusion, extracted data and assessed risk of bias. Studies were pooled using random effects meta-analysis and meta-regression was used to explore study-level predictors. Results Thirty-five studies with 10,703 participants (median follow-up 12 months) were included. Psychological interventions led to a reduction in cardiovascular mortality (rfcelative risk 0.79, 95% confidence interval [CI] 0.63 to 0.98), although no effects were observed for total mortality, myocardial infarction or revascularisation. Psychological interventions improved depressive symptoms (standardised mean difference [SMD] -0.27, 95% CI -0.39 to -0.15), anxiety (SMD -0.24, 95% CI -0.38 to -0.09) and stress (SMD -0.56, 95% CI -0.88 to -0.24) compared with controls. Conclusions We found that psychological intervention improved psychological symptoms and reduced cardiac mortality for people with CHD. However, there remains considerable uncertainty regarding the magnitude of these effects and the specific techniques most likely to benefit people with different presentations of CHD.

    Percutaneous coronary intervention in the setting of acute myocardial infarction is known to predict stent thrombosis (ST). This study aims to compare the ST rates across different coronary subsets. This was an observational cohort study from a large, single-center registry. Included were 12,198 consecutive patients who underwent percutaneous coronary intervention with stenting. Patients were categorized according to their clinical presentation: stable angina pectoris (SAP, n = 3,700), unstable angina pectoris (UAP, n = 2,845), non-ST-segment elevation myocardial infarction (NSTEMI, n = 4,083), and ST-segment elevation myocardial infarction (STEMI, n = 1,570). The study end points were ST rates at 1 year. Patients with STEMI were younger with a lower prevalence of cardiovascular risk factors, except for smoking. More type C lesions were treated in STEMI, whereas drug-eluting stents were used less frequently in patients with STEMI compared with the other groups. Definite ST at 1 year was highest in patients with STEMI (1.4%; vs SAP, 0.4%; UAP, 0.5%; NSTEMI, 0.5%; p <0.001). One-year definite/probable ST rates were SAP, 0.8%; UAP, 1.1%; NSTEMI, 1.4%; and STEMI, 3.2% (p <0.001). On multivariable analysis, STEMI independently predicts definite ST (hazards ratio [HR] 3.07, 95% confidence interval [CI] 1.32 to 7.10), whereas both STEMI (HR 3.36, 95% CI 1.84 to 6.12) and NSTEMI (HR 2.04, 95% CI 1.20 to 3.07) were independent predictors of definite/probable ST. Clopidogrel cessation was the strongest predictor of ST (definite ST, HR 17.00, 95% CI 7.54 to 38.31; definite/probable ST, HR 4.69, 95% CI 2.39 to 9.20). In conclusion, in patients who underwent percutaneous coronary intervention, the acuity of clinical presentation corresponds to an increase in ST incidence. Adherence to clopidogrel is critical to prevent ST in patients who underwent percutaneous coronary intervention, especially in STEMI. Copyright © 2014 Elsevier Inc. All rights reserved.

    Spontaneous reanalyzed coronary thrombus (SRCT) has been reported in autopsy series, but little is known about SRCT, and it is potentially under-diagnosed in clinical practice.Methods and Results:SRCT identified on OCT were included in a French multicenter series, the Lotus Root French Registry. A total of 34 SRCT were identified on OCT in 33 patients (23 male; median age, 56 years; IQR, 52-65 years); 23/33 patients (70%) presented with angina pectoris and/or dyspnea. Three angiographic aspects were distinguished retrospectively: braided, pseudo-dissected, and hazy. Stenosis severity on quantitative coronary analysis varied between 11% and 100% (median, 45%), whereas the reduction in lumen area on OCT varied between 20% and 92% (median, 68%). A typical "lotus root" aspect was confirmed on OCT, consisting of multiple circular concave-edged channels of varying size, numbering between 3 and 12 depending on the slice, separated by smooth-edged septa of high luminosity without posterior attenuation. OCT also served to guide treatment, with stenting in 91% of cases. During the 17-month follow-up 91% of patients had excellent evolution. One death and 3 ACS events occurred. In this large SRCT cohort, angiography had limited diagnostic value whereas OCT could be used to define disease characteristics and guide treatment of lesions inducing angina pectoris and/or silent myocardial ischemia. OCT-guided management was associated with good prognosis.

    The National Cardiovascular Disease (NCVD) Database Registry represents one of the first prospective, multi-center registries to treat and prevent coronary artery disease (CAD) in Malaysia. Since ethnicity is an important consideration in the occurrence of acute coronary syndrome (ACS) globally, therefore, we aimed to identify the role of ethnicity in the occurrence of ACS among high-risk groups in the Malaysian population. The NCVD involves more than 15 Ministry of Health (MOH) hospitals nationwide, universities and the National Heart Institute and enrolls patients presenting with ACS [ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA)]. We analyzed ethnic differences across socio-demographic characteristics, hospital medications and invasive therapeutic procedures, treatment of STEMI and in-hospital clinical outcomes. We enrolled 13,591 patients. The distribution of the NCVD population was as follows: 49.0% Malays, 22.5% Chinese, 23.1% Indians and 5.3% Others (representing other indigenous groups and non-Malaysian nationals). The mean age (SD) of ACS patients at presentation was 59.1 (12.0) years. More than 70% were males. A higher proportion of patients within each ethnic group had more than two coronary risk factors. Malays had higher body mass index (BMI). Chinese had highest rate of hypertension and hyperlipidemia. Indians had higher rate of diabetes mellitus (DM) and family history of premature CAD. Overall, more patients had STEMI than NSTEMI or UA among all ethnic groups. The use of aspirin was more than 94% among all ethnic groups. Utilization rates for elective and emergency percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) were low among all ethnic groups. In STEMI, fibrinolysis (streptokinase) appeared to be the dominant treatment options (>70%) for all ethnic groups. In-hospital mortality rates for STEMI across ethnicity ranges from 8.1% to 10.1% (p = 0

    Objective: To observe the clinical effects, safeness and prognosis of delayed percutaneous coronary intervention (PCI) for infarct related artery (IRA) in post-infarct patients. Methods: In total 53 patients with acute myocardial infarction (AMI) underwent delayed PCI within 5-15 days after the acute event. Conventional treatment (including thrombolytic therapy) was given in all patients as they were admitted. Results: Intervention was performed in 68 branches of IRA were, including 64 cases of PTCA followed by stent implantation and 4 cases of direct stent implantation. In total 68 stents were implanted. The TIMI classification was improved from the pre-PCI 0-2 to post-PCI 3. No patient died during the treatment. No repeated AMI, post-infarct angina and repeated recanalization happened in the hospitalization. A 5-48 month follow up showed there was 1 death (1.9%), 1 case of repeated myocardial infarction (1.9%), 3 cases of unstable angina (5.7%), 2 cases of repeated PCI and 1 case of CABG. The rate of repeated recanalization was 5.7%. Seven patients (13.2%) were admitted for the second time, who survived 6-48 months after the intervention. Conclusion: Delayed PCT can obviously improve the short and long term prognosis as well as the life quality of patients with AMI, which is a safe interventional procedure

    Although patients may experience a quick recovery followed by rapid discharge after percutaneous coronary interventions (PCIs), continuity of care from hospital to home can be particularly challenging. Despite this fact, little is known about the experiences of care across the interface between secondary and primary healthcare systems in patients undergoing PCI. To explore how patients undergoing PCI experience continuity of care between secondary and primary care settings after early discharge. The study used an inductive exploratory design by performing in-depth interviews of 22 patients at 6-8 weeks after PCI. Nine were women and 13 were men; 13 were older than 67 years of age. Eight lived remotely from the PCI centre. Patients were purposively recruited from the Norwegian Registry for Invasive Cardiology. Interviews were analysed by qualitative content analysis. Patients undergoing PCI were satisfied with the technical treatment. However, patients experienced an unplanned patient journey across care boundaries. They were not receiving adequate instruction and information on how to integrate health information. Patients also needed help to facilitate connections to community-based resources and to schedule clear follow-up appointments. As high-technology treatment dramatically expands, healthcare organisations need to be concerned about all dimensions of continuity. Patients are witnessing their own processes of healthcare delivery and therefore their voices should be taken into greater account when discussing continuity of care. Nurse-led initiatives to improve continuity of care involve a range of interventions at different levels of the healthcare system.

    Full Text Available Limited data are available regarding the long-term clinical outcomes of second-generation drug-eluting stents (DES versus first-generation DES in patients with coronary chronic total occlusion (CTO who undergo percutaneous coronary intervention (PCI. The aim of this study was to compare the clinical outcomes of second-generation DES with those of first-generation DES for the treatment of CTO.Between March 2003 and February 2012, 1,006 consecutive patients with CTO who underwent successful PCI using either first-generation DES (n = 557 or second-generation DES (n = 449 were enrolled in a multicenter, observational registry. Propensity-score matching was also performed. The primary outcome was cardiac death over a 2-year follow-up period. No significant differences were observed between the two groups regarding the incidence of cardiac death (first-generation DES versus second-generation DES; 2.5% vs 2.0%; hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.37 to 1.98; p = 0.72 or major adverse cardiac events (MACE, 11.8% vs 11.4%; HR: 1.00; 95% CI: 0.67 to 1.50; p = 0.99. After propensity score matching, the incidences of cardiac death (HR: 0.86; 95% CI: 0.35 to 2.06; p = 0.86 and MACE (HR: 0.93; 95% CI: 0.63 to 1.37; p = 0.71 were still similar in both groups. Furthermore, no significant differences were observed between sirolimus-eluting, paclitaxel-eluting, zotarolimus-eluting, and everolimus-eluting stents regarding the incidence of cardiac death or MACE.This study shows that the efficacy of second-generation DES is comparable to that of first-generation DES for treatment of CTO over 2 years of follow-up.

    ão ajudar a promover um melhor planejamento e manejo do atendimento da síndrome coronariana aguda a nível público e privado.BACKGROUND: Brazil lacks published multicenter registries of acute coronary syndrome. OBJECTIVE: The Brazilian Registry of Acute Coronary Syndrome is a multicenter national study aiming at providing data on clinical aspects, management and hospital outcomes of acute coronary syndrome in our country. METHODS: A total of 23 hospitals from 14 cities, participated in this study. Eligible patients were those who came to the emergency wards with suspected acute coronary syndrome within the first 24 hours of symptom onset, associated with compatible electrocardiographic alterations and/or altered necrosis biomarkers. Follow-up lasted until hospital discharge or death, whichever occurred first. RESULTS: Between 2003 and 2008, 2,693 ACS patients were enrolled, of which 864 (32.1% were females. T he final diagnosis was unstable angina in 1,141 patients, (42.4%, with a mortality rate of 3.06%, non-ST elevation acute myocardial infarction (AMI in 529 (19.6%, with mortality of 6.8%, ST-elevation AMI 950 (35.3%, with mortality of 8.1% and non-confirmed diagnosis 73 (2.7%, with mortality of 1.36%. The overall mortality was 5.53%. The multiple logistic regression model identified the following as risk factors for death regarding demographic factors and interventions: female gender (OR=1.45, diabetes mellitus (OR=1.59, body mass index (OR=1.27 and percutaneous coronary intervention (OR=0.70. A second model for death due to major complications identified: cardiogenic shock/acute pulmonary edema (OR=4.57, reinfarction (OR=3.48, stroke (OR=21.56, major bleeding (OR=3.33, cardiopulmonary arrest (OR=40.27 and Killip functional class (OR=3.37. CONCLUSION: The Brazilian Registry of Acute Coronary Syndrome data do not differ from other data collected abroad. The understanding of their findings may help promote better planning and management of acute coronary syndrome care

    Patients with diabetic nephropathy and unprotected left main (LM) coronary artery disease suffer from high cardiovascular morbidity and mortality. Although surgical revascularization is currently recommended in this special patient population, the optimal revascularization method for this distinct patient group has remained unclear. We collected 99 consecutive patients with unprotected LM disease and diabetic nephropathy, including 46 patients who had undergone percutaneous coronary intervention (PCI), and 53 who had coronary artery bypass grafting (CABG), with a mean age of 72 ± 10; with 80.8% male. Diabetic nephropathy was defined as overt proteinuria (proteinuria > 500 mg/day) and estimated glomerular filtration rate (eGFR) by the modified Modification of Diet in Renal Disease (MDRD) equation of less than 60 mL/min/1.73 m 2 . The baseline characteristics, angiographic results and long-term clinical outcomes were retrospectively analyzed. The baseline characteristic of all patients were similar except for smokers, low density lipoprotein (LDL) level and extension of coronary artery disease involvement. The median follow-up period was 3.8 years. There were 73 patients (74%) considered as high risk with additive European System for Cardiac Operative Risk Evaluation (EuroSCORE) ≥ 6. During follow-up period, the long term rate of all-cause death (PCI vs. CABG: 45.7% vs. 58.5%, p = 0.20) and all-cause death/myocardial infarction (MI)/stroke (PCI vs. CABG: 52.2% vs. 60.4%, p = 0.41) were comparable between the PCI and CABG group, whereas the repeat revascularization rate was significantly higher in the PCI group (PCI vs. CABG: 32.6% vs. 9.4%, p patients with unprotected LM disease and diabetic nephropathy, we found that PCI was a comparable alternative to CABG in terms of long-term risks of all-cause death/MI/stroke, with significantly higher repeat revascularization rate. Given the small patient number and retrospective nature, our findings should be validated by

    Interventional cardiology procedures are constantly increasing in numbers and in quality, especially in developing countries such as Egypt. The numbers and types of procedure now available have driven development in the field and in its accompanying services. The aim of this short report is to present a review of the development of interventional cardiology in Egypt during the period 2010-2015 and the demographic, economic and educational factors that have affected this process. We collected and analysed data provided by different centres and from the distributors of intervention tools for the years 2010 to 2015. Analysis of these data showed a steady growth of primary PCI, amounting to a threefold increase over the six-year period. There are increasing numbers of PCI-capable centres, especially in Cairo. Almost 55,000 PCIs are performed yearly in Egypt utilising around 100,000 stents; the percentage of drug-eluting stents (DES) used has increased to 65-70% (90% in private and insured patients). Structural intervention is growing fast for congenital heart disease, and balloon mitral valvuloplasty has become the default strategy. The numbers of TAVI and EVAR are also increasing, although cost remains the greatest challenge. These changes can be attributed to the increasing numbers of ischaemic heart disease patients over the last 25 years, involving improved education and awareness, patients presenting at a younger age, and improved practice in intervention. In Egypt, there has been a steady growth in PCI and intervention tools which has been faster in coronary and congenital heart disease than in structural heart disease during the period from 2010 to 2015.

    Purpose: The British Society of Interventional Radiology (BSIR) Inferior Vena Cava (IVC) Filter Registry was produced to provide an audit of current United Kingdom (UK) practice regarding placement and retrieval of IVC filters to address concerns regarding their safety. Methods: The IVC filter registry is a web-based registry, launched by the BSIR on behalf of its membership in October 2007. This report is based on prospectively collected data from October 2007 to March 2011. This report contains analysis of data on 1,434 IVC filter placements and 400 attempted retrievals performed at 68 UK centers. Data collected included patient demographics, insertion and retrieval data, and patient follow-up. Results: IVC filter use in the majority of patients in the UK follows accepted CIRSE guidelines. Filter placement is usually a low-risk procedure, with a low major complication rate ( 9 weeks versus those with a shorter dwell time. New lower limb deep vein thrombosis (DVT) and/or IVC thrombosis was reported in 88 patients following filter placement, there was no significant difference of incidence between filter types. Conclusions: This registry report provides interventional radiologists and clinicians with an improved understanding of the technical aspects of IVC filter placement to help improve practice, and the potential consequences of IVC filter placement so that we are better able to advise patients. There is a significant learning curve associated with IVC filter insertion, and when a filter is placed with the intention of removal, procedures should be in place to avoid the patient being lost to follow-up

    Acute kidney injury (AKI), a common and crucial complication of acute coronary syndrome (ACS) after receiving percutaneous coronary intervention (PCI), is associated with increased mortality and adverse outcomes. This study aimed to develop and validate a risk prediction model for incident AKI after PCI for ACS. We included 82,186 patients admitted for ACS and receiving PCI between 1997 and 2011 from the Taiwan National Health Insurance Research Database and randomly divided them into a training cohort (n = 57,630) and validation cohort (n = 24,656) for risk model development and validation, respectively. Risk factor analysis revealed that age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, chronic kidney disease (CKD), intra-aortic balloon pump (IABP) use, cardiogenic shock, female sex, prior stroke, peripheral arterial disease, hypertension, and heart failure were significant risk factors for incident AKI after PCI for ACS. The reduced model, ADVANCIS, comprised 8 clinical parameters (age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, CKD, IABP use, cardiogenic shock), with a score scale ranging from 0 to 22, and performed comparably with the full model (area under the receiver operating characteristic curve, 87.4% vs 87.9%). An ADVANCIS score of ≥6 was associated with higher in-hospital mortality risk. In conclusion, the ADVANCIS score is a novel, simple, robust tool for predicting the risk of incident AKI after PCI for ACS, and it can aid in risk stratification to monitor patient care.

  4. Role of depression in secondary prevention of Chinese coronary heart disease patients receiving percutaneous coronary intervention.

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    In a previous part of this study, the fluoroscopy dose rate was reduced in a cardiac catheterization laboratory. The objectives of the present study were to evaluate the effects in a clinical population undergoing percutaneous coronary intervention (PCI) of the dose-reducing measures detailed previously. Kerma area-product (KAP) values were first recorded for 154 patients undergoing PCI. Then, the fluoroscopy KAP rate was reduced from 44 to 16 mGy cm 2 /s by increasing filtration and reducing the image intensifier dose request. After this optimization, KAP was recorded for another 138 PCI procedures. After adjustment for differing proportions of combined procedures (coronary angiography+PCI), the total KAP was reduced to 67% of the original value with a 95% confidence interval from 57 to 78%, statistically significant. The mean total KAP values were 93.6 Gy cm 2 before and 69.1 Gy cm 2 after optimization. The KAP for digital acquisition did not change significantly. It is possible to make a large dose reduction in PCI by reducing the fluoroscopy dose rate. This dose reduction is beneficial for both patients and staff. (orig.)

    Cassar, Stephen; R Baldacchino, Donia

    Quality of life (QOL) is a complex concept comprised of biopsychosocial, spiritual and environmental dimensions. However, the majority of research addresses only its physical function perspectives. This two-part series examines the holistic perspective of QOL of patients after percutaneous coronary intervention (PCI). Part 1 explains the research process of a cross-sectional descriptive study and its limitations. Data were collected by a mailed WHOQOL-BREF questionnaire in Maltese from a systematic sample of patients who had undergone PCI; the response rate was 64% (n=228; males n=169, females n=59, age 40-89 years). Part 1 also considers limitations, such as its cross-sectional design and retrospective data collection. The hierarchy of human needs theory (Maslow, 1999) guided the study. Part 2 gives the findings on the holistic view of QOL. Having social and family support, as a characteristic of Maltese culture appeared to contribute towards a better QOL.

    Full Text Available Background: Medicor was established as the third cardiovascular center in Slovenia and started with percutaneous cardiovascular interventions in 2005. The purpose of our study was to describe the features and results of percutaneous coronary intervention (PCI performed between 2005 and 2015.Methods: Our retrospective descriptive study included consecutive patients undergoing PCI, who were enrolled in the PCI Registry. Patient characteristics, coronary anatomy, PCI features, use of coronary stents, procedural success and complications were investigated. Special emphasis was put on patients undergoing unprotected left main PCI.Results: During the study period, 1981 PCI procedures were performed. PCI patients were mainly men (73 %, their average age was 65+10 years and a majority (94 % had stable coronary disease with mutivessel involvement (62 %.

    Coronary venous dissection is a known complication of left ventricular lead placement during implantation of a cardiac resynchronization with defibrillator (CRT-D) system. A large-scale evaluation of the prevalence of coronary venous dissection and associated in-hospital clinical outcomes has not been performed. We sought to identify predictors of coronary venous dissection and evaluate subsequent in-hospital adverse events in those with the complication. We studied 140,991 first-time CRT-D recipients in the implantable cardioverter-defibrillator (ICD) Registry implanted between 2006 and 2011. Using hierarchical multivariable logistic regression adjusting for patient, implanting physician, and hospital characteristics, we examined predictors of coronary venous dissection and its association with other major complications, length of hospital stay, and in-hospital mortality. Coronary venous dissection occurred in 392 patients (0.28%). After multivariable adjustment, female gender and left bundle branch block were associated with greater odds of coronary venous dissection. Conversely, atrial fibrillation, previous coronary artery bypass graft, and higher implanter procedure volume were associated with lower odds of coronary venous dissection (all p values 3 days (OR 1.71, 95% CI 1.29 to 2.29, p <0.0001), but not in-hospital death (OR 0.78, 95% CI 0.12 to 5.25, p = 0.8012). In conclusion, in a large population of first-time CRT-D recipients, specific patient and implanter characteristics predicted coronary venous dissection risk. Coronary venous dissection was associated with major in-hospital complications and prolonged hospitalization, but not death. Copyright © 2017 Elsevier Inc. All rights reserved.

    Background Coronary artery disease (CAD) is the leading cause of mortality worldwide. The present study evaluated the impact of gender in patients hospitalized with acute coronary syndromes (ACS) over a 20-year period in Qatar. Methods Data were collected retrospectively from the registry of the department of cardiology for all patients admitted with ACS during the study period (1991–2010) and were analyzed according to gender. Results Among 16,736 patients who were admitted with ACS, 14262 (85%) were men and 2474 (15%) were women. Cardiovascular risk factors were more prevalent among women in comparison to men. On admission, women presented mainly with non-ST-elevation ACS and were more likely to be undertreated with β-blockers (BB), antiplatelet agents and reperfusion therapy in comparison to men. However, from 1999 through 2010, the use of aspirin, angiotensin-converting enzyme inhibitors and BB increased from 66% to 79%, 27% to 41% and 17% to 49%, respectively in women. In the same period, relative risk reduction for mortality was 64% in women and 51% in men. Across the 20-year period, the mortality rate decreased from 27% to 7% among the Middle Eastern Arab women. Multivariate logistic regression analysis showed that female gender was independent predictor of in-hospital mortality (odd ratio 1.51, 95% CI 1.27–1.79). Conclusions Women presenting with ACS are high-risk population and their in-hospital mortality remains higher for all age groups in comparison to men. Although, substantial improvement in the hospital outcome has been observed, guidelines adherence and improvement in the hospital care have not yet been optimized. PMID:23936143

  12. Contrast-Induced Nephropathy in Patients Undergoing Percutaneous Coronary Intervention

    2010-01-01

    Full Text Available Contrast Induced Nephropathy (CIN is a feared complication of numerous radiological procedures that expose patients to contrast media. The most notorious of these procedures is percutaneous coronary intervention (PCI. Not only is this a leading cause of morbidity and mortality, but it also adds to increased costs in high risk patients undergoing PCI. It is thought to result from direct cytotoxicity and hemodynamic challenge to renal tissue. CIN is defined as an increase in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2-3 days after contrast administration, after other causes of renal impairment have been excluded. The incidence is considerably higher in diabetics, elderly and patients with pre-existing renal disease when compared to the general population. The nephrotoxic potential of various contrast agents must be evaluated completely, with prevention as the mainstay of focus as no effective treatment exists. The purpose of this article is to examine the pathophysiology, risk factors, and clinical course of CIN, as well as the most recent studies dealing with its prevention and potential therapeutic interventions, especially during PCI. The role of gadolinium as an alternative to iodinated contrast is also discussed.

    To describe perceived social support among patients with coronary heart disease following percutaneous coronary intervention. A low level of social support is considered a risk factor for coronary heart disease in healthy individuals and reduces the likelihood that people diagnosed with coronary heart disease will have a good prognosis. A descriptive cross-sectional study. A survey of 416 patients was conducted in 2013. A self-report instrument, Social Support of People with Coronary Heart Disease, was used. The instrument comprises three dimensions of social support: informational, emotional, functional supports and 16 background variables. Data were analysed using descriptive statistics, factor analysis, mean sum variables and multivariate logistic regression. Perceived informational support was primarily high, but respondents' risk factors were not at the target level. The weakest items of informational support were advice on physical activity, continuum of care and rehabilitation. Regarding the items of emotional support, support from other cardiac patients was the weakest. The weakest item of functional support was respondents' sense of the healthcare professionals' care of patients coping with their disease. Background variables associated with perceived social support were gender, marital status, level of formal education, profession, physical activity, duration of coronary heart disease and previous myocardial infarction. Healthcare professionals should pay extra attention to women, single patients, physically inactive patients, those demonstrating a lower level of education, those with a longer duration of CHD, and respondents without previous acute myocardial infarction. Continuum of care and counselling are important to ensure especially among them. This study provides evidence that healthcare professionals should be more aware of the individual needs for social support among patients with coronary heart disease after percutaneous coronary intervention

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction. The disease is usually seen in young-middle aged women and leads to sudden death in the majority of cases. In survived patients, diagnosis of SCAD has been made with coronary anjiography. Involvement of left main coronary artery (LMCA is very unusual. We describe on a case of SCAD involving the LMCA in a young woman presenting with an acute myocardial infarction and cardiogenic shock status. There were no risk factors for coronary artery disease and no evidence of atherosclerosis on angiography. Coronary angiography revealed dissection of the LMCA that extended into the anterior descending and circumflex coronary arteries. The dissection was successfully treated with primary coronary artery stenting. The patient was discharged without complication. There was no problem in the first evaluation at the end of the first of the month. J Clin Exp Invest 2011; 2 (3: 299-303.

    To investigate whether patients with English as their second language have similar acute coronary syndrome (ACS) outcomes to people whose first language is English. Retrospective, observational study, using admissions, treatment and follow-up data. A total of 6304 subjects from 41 sites enrolled in the investigator-initiated CONCORDANCE ACS registry. Baseline characteristics, treatments, and in-hospital and 6-month mortality. English as a second language (ESL) was reported by 1005 subjects (15.9%). Patients with English as their first language (EFL) were older, and were less likely to have diabetes mellitus or to smoke than the ESL patients. Prior myocardial infarction, heart failure and chronic renal failure were more common in the ESL group. In-hospital mortality was also higher in these patients (7.1% v 3.8% for EFL patients; P language, age, in-hospital renal failure, and recurrent ischaemia as predictors of 6-month mortality. Patients presenting with an ACS who report English as their second language have poorer outcomes than patients who use English as their first language. This difference may not be entirely explained by baseline demographic disparities or management differences.

    The epidemiology and management of patients with acute coronary syndromes (ACSs) have evolved. We aimed to describe recent demographics and therapeutic changes in the Italian ACS population. We analyzed data from 2 multicenter consecutive Italian registries (the EYESHOT [EmploYEd antithrombotic therapies in patients with acute coronary Syndromes HOspitalised in iTalian cardiac care units] and START-ANTIPLATELET registries) enrolling patients with ACS between December 2013 and June 2016. An overall population of 3756 patients with ACS was enrolled: 2585 in the EYESHOT and 1171 in the START-ANTIPLATELET. Compared with the EYESHOT, patients in the START-ANTIPLATELET registry presented more frequently with ST-segment elevation myocardial infarction and were more often smokers and dyslipidemic (all P START-ANTIPLATELET (all P START-ANTIPLATELET compared with the EYESHOT. The START-ANTIPLATELET and EYESHOT registries provide consecutive snapshots in the contemporary management of patients with ACS in Italy, showing important changes in both demographic characteristics and treatment strategies.

    Purpose: The British Society of Interventional Radiology (BSIR) Inferior Vena Cava (IVC) Filter Registry was produced to provide an audit of current United Kingdom (UK) practice regarding placement and retrieval of IVC filters to address concerns regarding their safety. Methods: The IVC filter registry is a web-based registry, launched by the BSIR on behalf of its membership in October 2007. This report is based on prospectively collected data from October 2007 to March 2011. This report contains analysis of data on 1,434 IVC filter placements and 400 attempted retrievals performed at 68 UK centers. Data collected included patient demographics, insertion and retrieval data, and patient follow-up. Results: IVC filter use in the majority of patients in the UK follows accepted CIRSE guidelines. Filter placement is usually a low-risk procedure, with a low major complication rate (<0.5 %). Cook Gunther Tulip (560 filters: 39 %) and Celect (359 filters: 25 %) filters constituted the majority of IVC filters inserted, with Bard G2, Recovery filters, Cordis Trapease, and OptEase constituting most of the remainder (445 filters: 31 %). More than 96 % of IVC filters deployed as intended. Operator inexperience (<25 procedure) was significantly associated with complications (p < 0.001). Of the IVC filters initially intended for temporary placement, retrieval was attempted in 78 %. Of these retrieval was technically successful in 83 %. Successful retrieval was significantly reduced for implants left in situ for >9 weeks versus those with a shorter dwell time. New lower limb deep vein thrombosis (DVT) and/or IVC thrombosis was reported in 88 patients following filter placement, there was no significant difference of incidence between filter types. Conclusions: This registry report provides interventional radiologists and clinicians with an improved understanding of the technical aspects of IVC filter placement to help improve practice, and the potential consequences of IVC filter

    Patients with diabetes mellitus have worse outcomes after percutaneous coronary intervention than patients without diabetes mellitus. We compared the risk of stent thrombosis, myocardial infarction, death, and target lesion revascularization in diabetic and nondiabetic patients after implantation...... of drug-eluting stents or bare metal stents. In the Western Denmark Heart Registry, 12,347 consecutive patients (1,575 with and 10,772 without diabetes) were identified and followed up for 2 years. The 2-year risk of definite stent thrombosis was 0.52% in patients with diabetes mellitus and 0.......71% in nondiabetic patients (adjusted relative risk [RR] 0.74, 95% confidence interval [CI] 0.41 to 1.34, p = 0.321). The 2-year risk of myocardial infarction was greater in the diabetic patients (6.9%) than in the nondiabetic patients (3.6%; adjusted RR 1.96, 95% CI 1.58 to 2.43; p

    Full Text Available Percutaneous coronary intervention (PCI improves symptoms and prognosis in ischemia-inducing, functionally significant, coronary lesions. Use of fractional flow reserve allows physicians to investigate the ischemia-inducing potential of a specific lesion and can be used to guide coronary revascularization, especially in multivessel coronary artery disease. Fractional flow reserve-guided PCI has been extensively investigated. Results show that deferral of stenting in non-significant lesions is safe, whereas deferral of stenting in functionally significant lesions worsens outcome. FFR-guided PCI improves outcome in multivessel disease over angiography-guided PCI. Until recently, there was little known about the long-term outcome of FFR-guided revascularization and its validity in acute coronary syndromes. This review aims to address the new evidence regarding long-term appropriateness of FFR-guided PCI, the need for hyperemia to evaluate functional severity, and the use of FFR in acute coronary syndromes.

    Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y 12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered: The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y 12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert commentary: The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

    Contrast-induced nephropathy (CIN) is an important cause of acute renal failure. Identification of risk factors of CIN and creating a simple risk scoring for CIN after percutaneous coronary intervention (PCI) is important. A prospective single center study was conducted in Kuwait chest disease hospital. All patients admitted to chest disease hospital for PCI from March to May 2005 were included in the study. Total of 247 patients were randomly assigned for the development dataset and 100 for the validation set using the simple random method. The overall occurrence of CIN in the development set was 5.52%. Using multivariate analysis; basal Serum creatinine, shock, female gender, multivessel PCI, and diabetes mellitus were identified as risk factors. Scores assigned to different variables yielded basal creatinine > 115 micron mol/L with the highest score(7), followed by shock (3), female gender, multivessel PCI and diabetes mellitus had the same score (2). Patients were further risk stratified into low risk score ( 1 2). The developed CIN model demonstrated good discriminative power in the validation population. In conclusion, use of a simple risk score for CIN can predict the probability of CIN after PCI; this however needs further validation in larger multicenter trials. (author)

    Invasive fetal cardiac intervention (FCI) has been reported in single-institution series, promoting technical and physiologic success. This study describes the creation of an international registry of cases presenting for FCI, intended to compile technical and outcome data from a multicenter cohort. For this initial analysis, the entire database of the International Fetal Cardiac Intervention Registry (IFCIR) was queried for details of diagnoses, procedures, and outcomes. Maternal-fetal dyads from January 2001 through June 2014 were included. Eighteen institutions submitted data by data harvest. Of 370 cases entered, 245 underwent FCI: 100 aortic valvuloplasties from a previous single-center report (excluded from additional reporting here), an additional 86 aortic and 16 pulmonary valvuloplasties, 37 atrial septal cases, and 6 unclassified cases. FCI did not appear to affect overall survival to hospital discharge. Among live-born infants with a fetal diagnosis of aortic stenosis/evolving hypoplastic left heart syndrome, more than twice as many were discharged with biventricular circulation after successful FCI versus those meeting institutional criteria but without any or successful FCI (42.8% vs. 19.4%, respectively). When fetal deaths were counted as treatment failures, the percentages were similar: biventricular circulation at discharge was 31.3% versus 18.5% for those discharged with univentricular palliation. Survival to discharge for live-born fetuses with atrial restriction was similar to that of those undergoing technically successful versus unsuccessful FCI (63.6% vs. 46.7%, respectively), although criteria for diagnosis were nonuniform. We describe the contents of the IFCIR and present post-natal data to suggest potential benefit to fetal therapy among pregnancies considered for possible intervention and support proposals for additional work.

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

    Summary: Spontaneous coronary artery dissection (SCAD) is an uncommon but important cause of acute coronary syndrome. The diagnosis of SCAD by an angiogram alone can be challenging and the increasing use of intracoronary imaging has proven an invaluable diagnostic adjunct in this regard. The appropriate initial management of SCAD has been a matter of significant debate. Owing to frequent spontaneous healing of coronary dissection and a higher risk of complications with percutaneous coronary intervention (PCI) in the setting of SCAD, a default approach of mechanical revascularization is not recommended. However in the presence of vessel occlusion and on-going myocardial infarction PCI is mandated. Bioresorbable vascular scaffolds (BVS) offer potential advantages over the conventional stents in the setting of SCAD. We describe a state-of-the-art approach to the acute treatment of SCAD causing STEMI, utilizing intravascular ultrasound (IVUS), optical coherence tomography (OCT) and BVS and discuss management strategies for the modern era. - Highlights: • SCAD is an infrequent but important cause of acute coronary syndrome. • Intracoronary imaging is a useful adjunct in the diagnosis of SCAD. • Revascularization is recommended in the presence on-going myocardial infarction. • BVS may be considered preferable to conventional stents in the setting of SCAD.

    The prognostic value of high-sensitivity troponin T after percutaneous coronary intervention in patients with stable coronary artery disease is unclear. We investigated this clinically relevant question in 3463 consecutive patients undergoing percutaneous coronary intervention. This study included patients with stable coronary artery disease and baseline high-sensitivity troponin T below the 99th percentile upper reference limit (0.014μg/L). High-sensitivity troponin T was measured before and at 6, 12 and 24hours after the procedure. The primary outcome was all-cause mortality. Patients were divided into a group with peak postprocedural troponin T≤99th percentile (n=742), a group with peak postprocedural troponin T>99th to 5×99th percentile (n=1928), and a group with peak postprocedural troponin T>5×99th percentile upper reference limit (n=793). Advanced age, smaller body mass index, baseline troponin level, complex lesions, bifurcation lesions and stented length were independently associated with elevated troponin T levels after the procedure. The median follow-up was 15.5 months. There were 56 deaths: 5 deaths (1.7%) among patients with peak postprocedural troponin T≤99th percentile, 35 deaths (4.5%) among patients with peak postprocedural troponin T>99th to 5×99th percentile and 16 deaths (4.3%) among patients with peak postprocedural troponin T>5×99th percentile upper reference limit (hazard ratio=1.50; 95% confidence interval, 1.01-2.25; P=.047). After adjustment, peak postprocedural troponin T level was not independently associated with mortality after percutaneous coronary intervention (P=.094). In patients with stable coronary artery disease and without elevated baseline high-sensitivity troponin T, elevated high-sensitivity troponin T level after percutaneous coronary intervention was not associated with postprocedural mortality.

    Percutaneous coronary intervention (PCI) is a common invasive procedure for the treatment of coronary artery diseases. Long-term cognitive functioning after PCI and its association with health-related quality of life (HRQL) and psychological factors is relatively unknown. The aim of this study is to examine whether perceived cognitive functioning during the year after PCI is associated with HRQL over this time period, and whether mood, fatigue, and age are associated with changes in perceived cognition and HRQL. Patients undergoing PCI (n = 384, 79% male, mean age = 63, SD = 10) were recruited in the observational Tilburg Health Outcome Registry of Emotional Stress after Coronary Intervention (THORESCI) cohort study. Perceived concentration and attention problems, HRQL, mood, and fatigue were assessed at baseline, at 1-month and 12-month follow-up. General linear mixed modeling analysis showed that across time, between- and within-subject differences in perceived concentration problems were associated with a reduced HRQL in all domains independent of clinical and demographic covariates. Only a part of this association could be explained by negative mood, fatigue, and older age. Similar findings were found for between-subject differences in perceived attention problems. Between-subject differences and within-subject changes in perceived cognition in PCI patients were strongly associated with HRQL across time, such that poorer perceived cognition was associated with poorer HRQL, independent of demographic and clinical variables. Most of the associations were also independent of mood and fatigue. The results should increase the awareness of clinicians for the role of cognition in the cardiac rehabilitation and recovery post-PCI.

    Katowice-Zabrze registry provides data that can be used to evaluate clinical outcomes of percutaneous coronary interventions in elderly patients (≥70 y/o) treated with either first- (DES-I) or second-generation (DES-II) drug-eluting stents (DES). The registry consisted of data from 1916 patients treated with coronary interventions using either DES-I or DES-II stents. For our study, we defined patients ≥70 years of age as elderly. We evaluated any major adverse cardiac and cerebral events (MACCE) at 12-month follow-up. Coronary angiography revealed a higher incidence of multivessel coronary artery disease in this elderly patient population. There were no differences in acute and subacute stent thrombosis (0.4 vs. 0.6%, p = 0.760; 0.4 vs. 0.4%; p = 0.712). Elderly patients experienced more in-hospital bleeding complications requiring blood transfusion (2.0 vs. 0.9%; p = 0.003). Resuscitated cardiac arrests (2.0 vs. 0.9%; p = 0.084) were observed more often in this elderly patients during hospitalization. The composite in-hospital MACCE rates did not differ statistically between both groups (1.4 vs. 1.1%; p = 0.567). Data from a twelve-month follow-up disclosed that mortality was higher (7.1 vs. 1.8%; p < 0.001) in the elderly, with no difference in TVR (7.2 vs. 9.9%, p = 0.075), MI (6.0 vs. 4.8%, p = 0.300), stroke (0.8 vs. 0.6%, p = 0.600) and composite MACCE (15.0 vs. 13.4%, p = 0.324). The age of 70 years or over was an independent predictor of death [HR = 2.55 (95% CI 1.49-4.37); p < 0.001]. The use of DES-II reduced the risk of MI [HR = 0.40 (95% CI 0.19-0.82); p = 0.012] in the elderly. This elderly patient population had an increased risk of in-hospital bleeding complications requiring blood transfusion and a higher risk of death at 12-month follow-up. The use of new-generation DES reduced the risk of MI in the elderly population.

    Advantages and disadvantages of ad hoc percutaneous coronary intervention have been described. However little is known about the radiation exposure of that procedure as compared with the staged intervention. To compare the radiation dose of the ad hoc percutaneous coronary intervention with that of the staged procedure The dose-area product and total Kerma were measured, and the doses of the diagnostic and therapeutic procedures were added. In addition, total fluoroscopic time and number of acquisitions were evaluated. A total of 568 consecutive patients were treated with ad hoc percutaneous coronary intervention (n = 320) or staged percutaneous coronary intervention (n = 248). On admission, the ad hoc group had less hypertension (74.1% vs 81.9%; p = 0.035), dyslipidemia (57.8% vs. 67.7%; p = 0.02) and three-vessel disease (38.8% vs. 50.4%; p = 0.015). The ad hoc group was exposed to significantly lower radiation doses, even after baseline characteristic adjustment between both groups. The ad hoc group was exposed to a total dose-area product of 119.7 ± 70.7 Gycm 2 , while the staged group, to 139.2 ± 75.3 Gycm 2 (p < 0.001). Ad hoc percutaneous coronary intervention reduced radiation exposure as compared with diagnostic and therapeutic procedures performed at two separate times

Study population: All adult ($15 years patients undergoing coronary angiography (CAG, percutaneous coronary intervention (PCI, coronary artery bypass grafting, and heart valve surgery performed across all Danish hospitals were included. Main variables: The DHR contains a subset of the data stored in the Eastern and Western Denmark Heart Registries (EDHR and WDHR. For each type of procedure, up to 70 variables are registered in the DHR. Since 2010, the data quality protocol encompasses fulfillment of web-based validation rules of daily-submitted records and yearly approval of the data by the EDHR and WDHR. Descriptive data: The data collection on procedure has been complete for PCI and surgery since 2000, and for CAG as of 2006. From 2000 to 2014, the number of CAG, PCI, and surgical procedures changed by 231%, 193%, and 99%, respectively. Until the end of 2014, a total of 357,476 CAG, 131,309 PCI, and 60,831 surgical procedures had been performed, corresponding to 249,445, 100,609, and 55,539 first-time patients, respectively. The DHR generally has a high level of completeness (1–missing of each procedure (.90% when compared to the National Patient Registry. Variables important for assessing the quality of care have

    In the United States, there continues to be debate about whether certain types of hospitals deliver improved patient outcomes. We sought to assess the association between hospital organizational characteristics and in-hospital outcomes for percutaneous coronary intervention (PCI). Retrospective analysis of 2004 to 2007 data for 694 US hospitals participating in the CathPCI Registry(®). Our analysis focused on 1,113,554 patients who underwent PCI in 471 not-for-profit (NFP) hospitals, 131 major teaching hospitals, 79 for-profit (FP) hospitals, and 13 physician-owned specialty hospitals. Outcomes included in-hospital mortality, stroke, bleeding, vascular injury, and a composite representing one or more of the individual complications. We used the current CathPCI Registry mortality risk model to calculate risk-standardized mortality ratios (RSMRs) for each category of hospital and compared hospital groupings for all patients in aggregate and in subgroups stratified by patients' indications for PCI. Patients treated in major teaching hospitals were younger, whereas FP hospitals performed a greater proportion of PCI for patients with ST-elevation myocardial infarction (P < .0001). Specialty hospitals treated patients with less acuity, including a lower proportion of patients with ST-elevation myocardial infarction. In unadjusted analyses, specialty hospitals had significantly lower rates of all adverse outcomes compared with NFP, teaching, and FP hospitals including in-hospital mortality (0.7%, 1.2%, 1.4%, and 1.4%, respectively; P < .001) and the composite end point (2.4%, 4.1%, 4.6%, and 4.3%, respectively; P < .001). In adjusted analyses, RSMR was significantly lower for specialty hospitals when compared with the other 3 groups for all patients in aggregate (RSMR 1.05%, 1.30%, 1.38%, 1.39%; P < .001); these differences remained clinically significant but were no longer statistically significant in subgroup analyses. Specialty hospitals appear to have lower rates of

    The aim of this study was to compare the effects of residential multifactorial cardiac rehabilitation, outpatient multifactorial rehabilitation, stress management, and standard coronary rehabilitation, on cardiac risk reduction. Out of 144 eligible male patients recently treated with percantaneous transluminal coronary angiography (PTCA), coronary artery bypass graft (CABG), or acute myocardial infarction (AMI), 132 were randomized into this study. All interventions covered a 12-month active intervention, intense during the first months and subsequently leveled out. Main assessments were performed before randomization and after the intervention. Patients offered behavioral rehabilitation showed improved self-reported healthy diet habits and exercise frequency, and higher internal locus of control. Although blood lipids, exercise capacity, body mass, anxiety, depression, and Type A scores were changed in the expected direction, no significant difference emerged between active intervention and the standard care condition. Standard care of today appears to have great potential in particular if supplemented with some kind of stress management.

    Few data are available on primary percutaneous coronary intervention (pPCI) in nonagenarians. In a large prospective registry on pPCI for STEMI we compared the demographics, procedural and in-hospital outcomes between nonagenarians (age ≥ 90 years) and patients aged < 90 years. We included 26,157 consecutive patients with pPCI in the Greater Paris Area region between 2003 and 2011. Of these, 418 (1.6%) were ≥ 90 years old. Nonagenarians (versus patients < 90 years) were more likely to be female (62.3% versus 22.5%, p < 0.0001), nonsmokers (81.6% versus 36.7%, p < 0.0001), in cardiogenic shock (Killip IV) upon admission (10.5% versus 4.8%, p < 0.001), and had significant co-morbidities. Over two-thirds of patients underwent procedures via the radial artery (61% versus 72.1%, p = 0.007). Both groups had high and similar angiographic success rates (98.1% versus 98.7%, p = 0.33). Drug-eluting stents were used less often in nonagenarians (4.4% versus 16.7%, p < 0.0001). Hospital mortality was significantly much higher in patients over 90 years old (24.9% versus 5.1%, p < 0.001) in univariate analysis. After adjustment for sex, cardiogenic shock, diabetes, triple vessel disease, drug-eluting stent use and glycoprotein IIb/IIIa inhibitors use, mortality remains higher in nonagenarian patients (OR: 4.31; 95% CI: 3.26-5.71, p < 0.0001). In a real-world setting, we found important demographic differences in nonagenarian compared to younger patients. Despite achieving a high rate of reperfusion with pPCI using mainly radial access, similar to that achieved in younger patients, hospital mortality was higher in nonagenarians.

    Full Text Available Renal impairment is a well-known risk factor for cardiovascular complications, but the effect of different stages of renal impairment on thrombotic/thromboembolic and bleeding complications in patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI remains largely unknown. We sought to evaluate the incidence and clinical impact of four stages of renal impairment in patients with AF undergoing PCI.We assessed renal function by estimated glomerular filtration rate (eGFR and outcomes in 781 AF patients undergoing PCI by using the data from a prospective European multicenter registry. End-points included all-cause mortality, major adverse cardiac and cerebrovascular events (MACCE and bleeding events at 12 months.A total of 195 (25% patients had normal renal function (eGFR ≥90 mL/min, 290 (37% mild renal impairment (eGFR 60-89, 263 (34% moderate renal impairment (eGFR 30-59 and 33 (4% severe renal impairment (eGFR <30. Degree of renal impairment remained an independent predictor of mortality and MACCE in an adjusted a Cox regression model. Even patients with mild renal impairment had a higher risk of all-cause mortality (HR 2.25, 95%CI 1.02-4.98, p=0.04 and borderline risk for MACCE (HR 1.56, 95%CI 0.98- 2.50, p=0.06 compared to those with normal renal function.Renal impairment is common in patients with AF undergoing PCI and even mild renal impairment has an adverse prognostic effect in these patients requiring multiple antithrombotic medications.

    We examined clinical outcomes following percutaneous coronary intervention (PCI) in patients turned down for surgical revascularization across a broad population. Prior studies suggest that surgical ineligibility is associated with increased mortality in patients with unprotected left main or multivessel coronary artery disease undergoing PCI. This study included consecutive patients who underwent PCI in a multicenter registry in Michigan from January 2010 to December 2014. Surgical ineligibility required documentation indicating that a cardiac surgeon deemed the patient ineligible for surgery. In-hospital outcomes included mortality (primary outcome), cardiogenic shock, cerebrovascular accident, contrast-induced nephropathy (CIN), and a new requirement for dialysis (NRD). Of 99,370 patients at 33 hospitals with on-site surgical backup, 1,922 (1.9%) were surgically ineligible. The rate of ineligibility did not vary by hospital (range: 1.5-2.5%; P = 0.79). Overall, there were no major differences in baseline characteristics or outcomes between surgically ineligible patients and the rest (i.e., nonineligible patients): mortality (0.52% vs. 0.52%; P > 0.5), cardiogenic shock (0.68% vs. 0.73%; P > 0.5), cerebrovascular accident (0.05% vs. 0.19%; P = 0.28), NRD (0.16% vs. 0.19%; P > 0.5), CIN (2.7% vs. 2.3%; P = 0.27). Among 1,074 patients who underwent unprotected left main PCI, 20 (1.9%) were surgically ineligible and experienced increased rates of mortality (20.0% vs. 5.3%; P = 0.022; adjusted OR = 7.38; P < 0.001) and other complications as compared to the remainder. PCI in a broad population of surgically ineligible patients is generally safe. However, among patients who underwent unprotected left main PCI, those deemed surgically ineligible experienced significantly worse outcomes as compared to the rest. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    This study compared prognoses of myocardial infarction related to percutaneous coronary intervention (PCI, procedural MI) using increasing creatine kinase-myocardial band (CK-MB) thresholds with spontaneous MI. Procedural MI usually is defined by a CK-MB elevation of more than 3 times the upper limit of normal (ULN), but higher thresholds have been proposed. Patients from the EARLY-ACS (Early Glycoprotein IIb/IIIa Inhibition in Non-ST-Segment Elevation Acute Coronary Syndrome) study and the SYNERGY (Superior Yield of the New strategy of Enoxaparin, Revascularization and GlYcoprotein IIb/IIIa inhibitors) study treated with PCI were included. The primary end point was 1-year all-cause mortality from 24 h after PCI. To determine an enzymatic threshold for procedural MI with a prognosis similar to that of spontaneous MI, we redefined procedural MI using increasing CK-MB thresholds and compared corresponding hazard ratios with those of spontaneous MI (CK-MB more than twice the ULN). Hazard ratios for mortality for procedural and spontaneous MI were calculated using Cox proportional hazards regression and Global Registry of Acute Cardiac Events covariates for risk adjustment. Nine thousand eighty-seven patients who underwent PCI (46.8%) were included; 773 procedural MI and 239 spontaneous MI occurred within 30 days. Adjusted hazard ratios for 1-year death were 1.39 (95% confidence interval [CI]: 1.01 to 1.89) for procedural MI and 5.37 (95% CI: 3.90 to 7.38) for spontaneous MI. The CK-MB threshold for procedural MI that achieved the same prognosis as spontaneous MI was 27.7 times the ULN (95% CI: 13.9 to 58.4), but this differed between the SYNERGY study (57.9 times the ULN, 95% CI: 17.9 to 63.6) and the EARLY-ACS study (20.4 times the ULN, 95% CI: 5.16 to 24.2). Of all procedural MI, 49 (6%) had CK-MB elevations of 27.7 or more times the ULN. The current enzymatic definition of procedural MI (CK-MB more than 3 times the ULN) used in clinical trials is less strongly

    Dual antiplatelet therapy is essential in patients undergoing percutaneous coronary intervention with stent implantation. Hypersensitivity to acetylsalicylic acid (ASA) limits treatment options. Desensitization to ASA has classically been studied in patients with respiratory tract disease. Over the last years, many protocols have been described about ASA desensitization in patients with ischemic heart disease, including acute coronary syndrome and the need for coronary stent implantation. It is important to know the efficacy and safety of ASA desensitization in these patients. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Full Text Available Objectives: To compare the efficacy and safety of percutaneous coronary intervention using second-generation drug-eluting stents with those of coronary artery bypass grafting among patients with multivessel disease and/or unprotected left main coronary artery disease in terms of mortality, myocardial infarction, repeat revascularization, and angina. Background: Although coronary artery disease is a leading cause of death in the Western world and in many developing countries, its optimal treatment is still a matter of controversy. Several studies have examined the clinical safety and efficacy of percutaneous coronary intervention using first-generation drug-eluting stents over coronary artery bypass grafting in patients with multivessel disease and/or unprotected left main coronary artery disease. However, this study compared the efficacy of percutaneous coronary intervention using second-generation drug-eluting stents to that of coronary artery bypass grafting for multivessel disease and/or unprotected left main coronary artery disease. Methods: This was a prospective single-center cohort study conducted from September 2012 to November 2014 at the Nicosia General Hospital. In total, 140 patients (94% men and 6% women with chronic coronary artery disease undergoing revascularization with either percutaneous coronary intervention using second-generation drug-eluting stents or coronary artery bypass grafting were evaluated. We examined the differences in clinical outcomes between coronary artery bypass grafting and percutaneous coronary intervention at 1-year follow-up. Results: Percutaneous coronary intervention with second-generation drug-eluting stents as opposed to coronary artery bypass grafting resulted in similar rates of mortality (5.7% vs 11.4%, respectively; p = 0.135, myocardial infarction (0% vs 4.3%, respectively, repeat revascularization (4.3% vs 8.6%, respectively; p = 0.115 and angina (10% vs 18.6%, respectively; p = 0

    Objective The aim of this study was to investigate whether the use of low frame rate fluoroscopy at 7.5 frames per second during coronary intervention could reduce radiation exposure in Japanese patients. Methods From December 10, 2014 to March 20, 2015, 84 consecutive patients with coronary artery disease who underwent coronary intervention in our institution were retrospectively collected and then divided into two groups: the LR group (fluoroscopy at 7.5 frames per second) and the OR group (fluoroscopy at 15 frames per second), according to the frame rate of fluoroscopy that was used in their treatment. Results There were no differences in the patient backgrounds or the procedural characteristics of the two groups. Although there were no differences in the contrast volume or fluoroscopy time, the total air kerma at the interventional reference point, which is used to monitor the patient's radiation dose, was significantly lower in the LR group than in the OR group (701.4±427.9 vs. 936.8±623.9 mGy, p=0.02). Conclusion Low frame rate fluoroscopy at 7.5 frames per second is safe and feasible for use during coronary interventions and an easy and useful strategy for reducing the radiation to which patients are exposed during coronary intervention.

    Full Text Available Background: Identifying clinical variables influencing the results of percutaneous coronary intervention is a very valuable element in the management of patients suffering from myocardial ischemia. Objective: To describe the relationship between the following clinical variables: positive results of coronary angiography and conventional stents implantation in patients suffering from acute coronary syndrome.Methods: A descriptive study was conducted. The sample consisted of 200 patients from Cienfuegos province who underwent angiography at the Cardiology Center of Santa Clara, in 2009. Age, sex, morbidity and results of coronary angiography, were used as clinical variables and were analyzed in relation to the use of therapeutic intervention. The relationship between clinical variables and results was identified.Results: The main result was the positive test in 46.5 % patients, with predominant affection of the anterior descending artery (35.5 %, allowing possible therapeutic intervention in 47.8 % of these patients. In relation to the use of therapeutic intervention, a significant relationship was found between sex (p = 0.002, smoking history (p = 0.004, diabetes mellitus (p = 0.000 and dyslipidemia (p = 0.000 with positive results, diabetes mellitus (OR = 4.2, p = 0.000 and dyslipidemia (OR = 3.7, p = 0.000. Conclusions: This study revealed the importance of coronary angiography, especially in diabetic and dyslipidemic patients, because of its relationship with positive results and the use of interventional treatment.

During hospitalization, 87.9% of patients were given a beta-blocker, 95.9% acetylsalicylic acid, 89.9% anti-thrombin therapy, 86.2% intravenous nitroglycerin, 6.4% glycoprotein (GP IIb/IIIa receptor inhibitor, 35.9% clopidogrel, 77.9% angiotensin-converting enzyme inhibitor, and 70,9% statin drugs. Coronary arteriography was performed in 72 patients (92.3% with STEMI, and in 452 (59.8% with non-STEMI ACS (p< 0.0001. Myocardial revascularization (MR surgery was indicated for 12.9% and percutaneous coronary intervention for 26.6%. In-hospital mortality was 4.8%, and no difference was recorded between the proportion of deaths among patients with STEMI and non-STEMI ACS (6.4% versus 4.8%; p = 0.578. CONCLUSION: In this registry, we provide a description of ACS patient, which allows the evaluation of the demographic characteristics, medical treatment prescribed, and in-hospital mortality. A greater awareness of our reality may help the medical community to adhere more strictly to the procedures set by guidelines.

    Full Text Available Aim. The study was aimed at comparing the immediate and long-term results of aortic valve replacement in combination with various techniques of intervention for myocardial revascularization, namely: coronary artery bypass grafting (CABG and percutaneous transluminal coronary angioplasty (PTCA.Methods. This randomized prospective controlled study involved 120 cardiac patients over 18 years old with combined aortic valve stenosis and arterial sclerotic disease of coronary arteries. The inclusion criteria were a combination of aortic valve stenosis and a hemodynamically significant lesion of the coronary bed. A comparative analysis of the results obtained in the nearest postoperative period and during 1-year follow-up is presented. Results. Hybrid intervention (aortic valve replacement + percutaneous transluminal coronary angioplasty produces the results which are comparable with those of the control (aortic valve replacement + CABG, with a significantly greater decrease in the peak gradient on the aortic valve. During long-term follow-up, the group of patients who underwent hybrid intervention demonstrated a much higher myocardial infarction rate (12.5 versus 2.5 %, however, the severity of infarctions was significantly lower.Conclusion. PTCA, as compared to CABG, with concomitant coronary artery disease significantly improves the indicators of aortic valve insufficiency and the survival after repeated myocardial infarction, with the matching frequency of acute cerebral circulation abnormalities and the lethality rate in the long-term period.Received 29 August 2016.

    2016-01-01

    Arteria Lusoria or aberrant right subclavian artery (ARSA) is present in 0.6–1.4% of individuals. It typically remains clinically silent and is often discovered during angiographic procedures. The presence of ARSA can make a right transradial approach for coronary angiography and angioplasty technically more difficult. With the use of catheter support, we describe two cases in which a right transradial approach for catheterization was successful in the setting of ARSA. As such, the presence of ARSA does not warrant abandoning a transradial approach for coronary angiography and angioplasty. PMID:27478652

    The effects of renin-angiotensin system (RAS) blockade on the clinical outcome in patients with stable coronary artery disease (SCAD) are conflicting. We evaluated the long-term effects of RAS blockers (angiotensin-converting enzyme inhibitor or angiotensin receptor blocker) on the clinical outcomes in patients with SCAD without heart failure (HF) who underwent percutaneous coronary intervention (PCI) with drug-eluting stent using a large-scale, multicenter, prospective cohort registry. A total of 5722 patients with SCAD were enrolled and divided into two groups according to the use of RAS blockers after PCI: RAS blocker group included 4070 patients and no RAS blocker group included 1652 patients. Exclusion criteria were left ventricular ejection fraction less than 50% and the history of HF or myocardial infarction. A major adverse cardiovascular event (MACE) was defined as a composite of cardiovascular death, nonfatal myocardial infarction, and stroke. During a median follow-up of 29.7 months, RAS blockers were associated with a significant reduction in the risk of MACE [adjusted hazard ratio (HR): 0.781; 95% confidence interval (CI): 0.626-0.975; P=0.015] and all-cause death (adjusted HR: 0.788; 95% CI: 0.627-0.990; P=0.041) but did not affect the risk of coronary revascularization. In the propensity score matched cohort, overall findings were consistent (MACE: adjusted HR: 0.679; 95% CI: 0.514-0.897; P=0.006; all-cause death: adjusted HR: 0.723; 95% CI: 0.548-0.954; P=0.022), and the benefit of RAS blockade was maintained in all predefined subgroups. This study demonstrated that RAS blockers were effective preventive therapies for reducing long-term cardiovascular events in patients with SCAD without HF who underwent PCI.

    The goal of this study was to determine the effects of exercise training (ET) on functional capacity and quality of life (QOL) in patients who received percutaneous transluminal coronary angioplasty (PTCA) or coronary stenting (CS), the effects on the restenosis rate and the outcome. It is unknown whether ET induces beneficial effects after coronary angioplasty. We studied 118 consecutive patients with coronary artery disease (mean age 57+/-10 years) who underwent PTCA or CS on one (69%) or two (31%) native epicardial coronary arteries. Patients were randomized into two matched groups. Group T (n = 59) was exercised three times a week for six months at 60% of peak VO2. Group C (n = 59) was the control group. Only trained patients had significant improvements in peak VO2 (26%, p < 0.001) and quality of life (26.8%, p = 0.001 vs. C). The angiographic restenosis rate was unaffected by ET (T: 29%; C: 33%, P = NS) and was not significantly different after PTCA or CS. However, residual diameter stenosis was lower in trained patients (-29.7%, p = 0.045). In patients with angiographic restenosis, thallium uptake improved only in group T (19%; p < 0.001). During the follow-up (33+/-7 months) trained patients had a significantly lower event rate than controls (11.9 vs. 32.2%, RR: 0.71, 95% confidence interval [CI]: 0.60 to 0.91, p = 0.008) and a lower rate of hospital readmission (18.6 vs. 46%, RR: 0.69, 95% CI: 0.55 to 0.93, p < 0.001). Moderate ET improves functional capacity and QOL after PTCA or CS. During the follow-up, trained patients had fewer events and a lower hospital readmission rate than controls, despite an unchanged restenosis rate.

    To analyse intensity of treatment of high-risk patients with non-ST elevation acute coronary syndromes (NSTEACS) included in the DESCARTES (Descripción del Estado de los Sindromes Coronarios Agudos en un Registro Temporal Español) registry. Patients with NSTEACS (n = 1877) admitted to 45 randomly selected Spanish hospitals in April and May 2002 were studied. Patients with ST segment depression and troponin rise were considered high risk (n = 478) and were compared with non-high risk patients (n = 1399). 46.9% of high-risk patients versus 39.5% of non-high-risk patients underwent angiography (p = 0.005), 23.2% versus 18.8% (p = 0.038) underwent percutaneous revascularisation, and 24.9% versus 7.4% (p or = 4, 2-3 and or = 4 (OR 2.87, 95% CI 1.27 to 6.52, p = 0.012). Class I recommended treatments were underused in high-risk patients in the DESCARTES registry. This undertreatment was an independent predictor of death of patients with an acute coronary syndrome.

    Objective: To investigate the effects of percutaneous coronary interventional therapy on platelet activation and the systemic fibrinolysis in patients with coronary artery disease (CAD). Methods: The plasma concentration of platelet alpha-granule membrane glycoprotein-140 (GMP-140), plasminogen activator inhibitor-1 (PAI-1), tissue-type plasminogen activator (t-PA), von Willebrand factor (vWF) and D-dimer (D-D) of the blood sampled from vein according to the schedule were measured by ELISA. Results: In the sixty-five patients with CAD, at 10 minutes after the procedure, plasma levels of GMP-140, t-PA and D-D were significantly higher than the previous ones; and at 24 h, plasma levels of PAI-1 and vWF were also increased significantly. Conclusions: The activation of platelet and impaired fibrinolytic activity were occurred after PCI in the patients with CAD

    Advances in coronary artery bypass grafting (CABG) surgery and percutaneous coronary intervention (PCI) with drug-eluting stents have dramatically improved results of these procedures. The optimal treatment for patients with multivessel coronary artery disease is uncertain given the lack of prospective, randomized data reflecting current practice. This study represents a "real-world" evaluation of current technology in the treatment of multivessel coronary artery disease. A total of 1680 patients undergoing revascularization for multivessel coronary artery disease were identified. Of these, 1080 patients were treated for 2-vessel disease (196 CABG and 884 PCI) and 600 for 3-vessel disease (505 CABG and 95 PCI). One-year mortality, cerebrovascular events, Q-wave myocardial infarction, target vessel failure, and composite major adverse cardiovascular and cerebrovascular events were compared between the CABG and PCI cohorts. Outcomes were adjusted for baseline covariates and reported as hazard ratios. The unadjusted major adverse cardiovascular and cerebrovascular event rate was reduced with CABG for patients with 2-vessel disease (9.7% CABG versus 21.2% PCI; P<0.001) and 3-vessel disease (10.8% CABG versus 28.4% PCI; P<0.001). Adjusted outcomes showed increased major adverse cardiovascular and cerebrovascular event with PCI for patients with 2-vessel (hazard ratio 2.29; 95% CI 1.39 to 3.76; P=0.01) and 3-vessel disease (hazard ratio 2.90; 95% CI 1.76 to 4.78; P<0.001). Adjusted outcomes for the nondiabetic subpopulation demonstrated equivalent major adverse cardiovascular and cerebrovascular event with PCI for 2-vessel (hazard ratio 1.77; 95% CI 0.96 to 3.25; P=0.07) and 3-vessel disease (hazard ratio 1.70; 95% CI 0.77 to 3.61; P=0.19). Compared with PCI with drug-eluting stents, CABG resulted in improved major adverse cardiovascular and cerebrovascular event in patients with 2- and 3-vessel coronary artery disease, primarily in those with underlying diabetes

    Full Text Available Abstract Of the associations between dietary elements and coronary artery disease (CAD, the greatest body of evidence deals with the beneficial effect of reducing the dietary intake of saturated fatty acids and cholesterol. Furthermore, it is well established, on the basis of convincing evidence, that reduction in serum total cholesterol results in reduction in coronary morbidity and mortality, as well as in regression of other atherosclerotic manifestations.In fact, dietary intervention studies revealed that it is possible to reduce the incidence of coronary death and nonfatal myocardial infarction, as well as manifestations of atherosclerosis in cerebral and peripheral arteries, by reducing dietary intake of saturated fat and cholesterol. In two recently reported dietary interventions the incidence of coronary events, especially coronary mortality, and total mortality were reduced by increased intake of n-3 long-chain polyunsaturated fatty acids and by a modification of the diet toward a Mediterranean-type diet (rich in α-linolenic acid. In addition to those findings, the potential efficacy of the dietary newcomers phytostanol and phytosterol esters on reducing coronary incidence is discussed in the present review.

    Recent studies have showed that the fine mesh stents are associated with a significant reduction in both clinical and angiographic re-stenosis of the coronary arteries. To maintain a very satisfactory radio-opacity using the stents, Guidant of the USA has designed a new type of bare metal stents (BMS)-Multi-link (ML) Vision/ML MiniVision stents. The clinical outcomes of Asian patients with coronary artery disease (CAD) after implanting the Multi-link Vision or MiniVision stent were investigated in this study. An observational, prospective, multi-center, non-randomized post marketing registry was conducted to demonstrate the efficacy of the BMS-ML Vision/ML MiniVision stents. The primary end point of the registry was clinical target lesion revascularization (TLR) at a 6-month follow-up. The major secondary end points included the rate of major adverse cardiac events (MACE) and serious adverse events (SAE) in hospital and at 6 months; and the rate of clinical TLR as a function of the type of angina. A total of 429 Asian people with 449 lesions from 14 centers were selected for this study. The average reference diameter of the lesions was (3.0 +/- 0.5) mm, and the mean length was (15.7 +/- 5.0) mm. The successful rate of the procedure was 99.3%. Twenty-five percent of the lesions were treated by direct stenting without pre-dilation. Eighty-six percent of the lesions were implanted with ML Vision stent. After the 6-month follow-up, the rate of clinical TLR was 1.4%. The MACE, SAE and target vessel revascularization (TVR) were 6.8%, 3.5% and 1.4% respectively. The current registry showed the excellent 6-month clinical outcomes of ML Vision/ML MiniVision stents in Asian patients with CAD.

    This study assessed the effect of pharmacogenetics on the antiplatelet effect of clopidogrel. Variability in clopidogrel response might be influenced by polymorphisms in genes coding for drug metabolism enzymes (cytochrome P450 [CYP] family), transport proteins (P-glycoprotein) and/or target proteins for the drug (adenosine diphosphate-receptor P2Y12). Sixty patients undergoing elective percutaneous coronary intervention in the randomized PRINC (Plavix Response in Coronary Intervention) trial had platelet function measured using the VerifyNow P2Y12 analyzer after a 600-mg or split 1,200-mg loading dose and after a 75- or 150-mg daily maintenance dosage. Polymerase chain reaction-based genotyping evaluated polymorphisms in the CYP2C19, CYP2C9, CYP3A4, CYP3A5, ABCB1, P2Y12, and CES genes. CYP2C19*1*1 carriers had greater platelet inhibition 2 h after a 600-mg dose (median: 23%, range: 0% to 66%), compared with platelet inhibition in CYP2C19*2 or *4 carriers (10%, 0% to 56%, p = 0.029) and CYP2C19*17 carriers (9%, 0% to 98%, p = 0.026). CYP2C19*2 or *4 carriers had greater platelet inhibition with the higher loading dose than with the lower dose at 4 h (37%, 8% to 87% vs. 14%, 0% to 22%, p = 0.002) and responded better with the higher maintenance dose regimen (51%, 15% to 86% vs. 14%, 0% to 67%, p = 0.042). Carriers of the CYP2C19*2 and *4 alleles showed reduced platelet inhibition after a clopidogrel 600-mg loading dose but responded to higher loading and maintenance dose regimens. Genotyping for the relevant gene polymorphisms may help to individualize and optimize clopidogrel treatment. (Australia New Zealand Clinical Trials Registry; ACTRN12606000129583).

    Full Text Available Cardiac catheterization and percutaneous coronary intervention play an important role in the management of coronary artery disease. Although the transfemoral approach has been the traditionally dominant method, there has been an increased utilization of the transradial approach. Multiple observational studies and randomized clinical trials have shown fewer bleeding complications, reduced morbidity and mortality, improved quality of life, and better economic outcomes when the transradial approach is utilized when compared to the transfemoral approach. Despite its many benefits, utilization of this approach in certain countries including the United States has been less than optimal due to a lower adoption rates mostly driven by lack of training opportunities and decreased awareness of clinical benefits of the transradial approach. In this review, the history, observational trends, efficacy, and technical aspects of transradial cardiac catheterization and percutaneous coronary intervention are discussed.

    Full text: Objective: To survey and assess radiation dose to patients from coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) in Beijing Xuanwu Hospital of Capital University of Medical Sciences. Methods: The dose-area product (DAP) values to the patient and cumulative dose (CD) were recorded from 84 coronary angiographies and 51 percutaneous transluminal coronary angioplasty. A Monte-Carlo based program PCXMC was used to calculate the effective dose from DAP values for each patient. Organ doses were also measured by thermoluminescent dosimeters (TLD) using a human-shaped phantom to compare the calculated organ dose from DAP. Results: The difference between the organ doses measured by TLDs and those from PCXMC software (P>0.05) were tolerable. The DAP value ranged from 7611∼60538 mGy·cm 2 for CA and 16423∼161973 mGy·cm 2 for PTCA. The effective dose for all procedures was determined to be in the range of 1.1∼6.9 mSv for CA and 2.3∼20.1 mSv for PTCA. CD ranged from 120.0 to 1016.0 mGy for CA and 287 to 2883 mGy for PTCA. Conversion factors between effective dose and DAP were 0.114∼0.139 mSv·Gy - 1·cm -2 for CA and 0.124∼0.142 mSv·Gy -1 ·cm -2 for PTCA; Conversion factors between organ dose and CD were derived for CA and PTCA, respectively. Conclusions: DAP and CD can be used as the dose indicator to calculate the organ dose and effective dose of patient based on Monte Carlo simulation. Using this method can provide important information of patient absorbed dose and enhance the radiation protection of patient in interventional radiology procedures. (author)

    Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

    OBJECTIVE: To investigate the feasibility and safety of using sheathless standard guiding catheters for transradial percutaneous coronary intervention (PCI) to treat bifurcation lesions. METHODS: Coronary bifurcation lesions were identified using angiography in 43 patients with coronary artery disease. These patients underwent transradial PCI using sheathless standard guiding catheters, and the procedural success and complication rates were recorded. RESULTS: All 43 patients underwent successful PCI. The Culotte stenting technique was used in 22 (51.2%) subjects, the Crush stenting technique was used in eight (18.8%) subjects and the crossover stenting implantation technique was used in 13 (30.0%) subjects. Of the 43 coronary artery bifurcation lesions, the final kissing balloon technique was performed in 39 (90.1%) lesions. Adjunctive devices used in the cohort included intravascular ultrasound for 32 (74.4%) patients, thrombus aspiration catheters for two patients and cutting balloon for five patients. During the perioperative period, no major complications associated with vessel puncture or adverse cardiac or cerebrovascular events occurred in any of the 43 patients enrolled in the present study. At day 30, radial artery occlusion was detected in only three (2.5%) patients and radial artery stenosis in four (9.3%) patients. At six-month follow-up, 24 (55.8%) patients exhibited coronary artery patency with no significant intimal hyperplasia. CONCLUSIONS: Transradial PCI using the sheathless technique may be a feasible and safe technique to treat coronary bifurcation lesions. PMID:23940423

    Occlusion of the right coronary artery (RCA) may promote atrial fibrillation (AF) by creating a right atrial substrate. However, the presence and extent of coronary artery disease (CAD) is usually not considered to tailor AF ablation strategies. This study was aimed to analyze the possible association between the presence and extent of CAD and rhythm outcomes of left-atrial AF catheter ablation. 1310 patients (60 ± 10 years, 67% males, 63% paroxysmal AF) from The Leipzig Heart Center AF Ablation Registry undergoing de novo AF catheter ablation were included. CAD was defined as stenosis ≥ 50% in the left main coronary artery and ≥ 70% in one or several of the major coronary arteries. AF recurrences were defined as any atrial arrhythmia lasting >30s and occurring within the first week (early recurrences, ERAF) or between 3 and 12 months (late recurrences, LRAF) after ablation and were assessed with serial 7-day Holter ECG. 152 patients (11.6%) had significant CAD; 89 (59%) had one, 35 (23%) two and 28 (18%) three vessel disease; 72 (47%) patients had RCA involvement. Occurrence of AF recurrences was comparable in CAD (p=0.625 and 0.568 for ERAF and LRAF, respectively). Among patients with CAD, neither the location (RCA versus non-RCA) nor the extent of CAD (single versus multiple vessel disease) was associated with rhythm outcomes after AF catheter ablation (all p>0.05). The presence and extent of CAD seem not to impact on rhythm outcome of AF catheter ablation in the entire cohort. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Among patients receiving clopidogrel for coronary artery disease, concomitant therapy with proton pump inhibitors (PPIs) has been associated with an increased risk for recurrent coronary events. Factores de Riesgo y ENfermedad Arterial (FRENA) is an ongoing, multicenter, observational registry of consecutive outpatients with coronary artery disease, cerebrovascular disease, or peripheral artery disease. We retrospectively examined the influence of concomitant use of PPIs on outcome in patients receiving clopidogrel. As of March 2009, 1222 patients were using clopidogrel: 595 had coronary artery disease, 329 cerebrovascular disease, and 298 had peripheral artery disease. Of these, 519 (42%) were concomitantly using PPIs. Over a mean follow-up of 15 months, 131 patients (11%) had 139 subsequent ischemic events: myocardial infarction 44, ischemic stroke 40, and critical limb ischemia 55. Seventeen of them (13%) died within 15 days of the subsequent event. PPI users had a higher incidence of myocardial infarction (rate ratio, 2.5; 95% confidence interval [CI], 1.3-4.8), ischemic stroke (rate ratio, 1.9; 95% CI, 1.03-3.7), and a nonsignificantly higher rate of critical limb ischemia (rate ratio, 1.6; 95% CI, 0.95-2.8) than nonusers. On multivariate analysis, concomitant use of clopidogrel and PPIs was independently associated with an increased risk for subsequent ischemic events both in the whole series of patients (hazard ratio, 1.8; 95% CI, 1.1-2.7) and in those with cerebrovascular disease or peripheral artery disease (hazard ratio, 1.5; 95% CI, 1.01-2.4). In patients with established arterial disease, concomitant use of PPIs and clopidogrel was associated with a nearly doubling of the incidence of subsequent myocardial infarction or ischemic stroke. This higher incidence persisted after multivariate adjustment.

    While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

    Full Text Available Background: Studies have shown controversial effects of obesity on major adverse cardiac events (MACE after percutaneous coronary intervention (PCI. We sought to investigate the impact of the body mass index (BMI on the mid-term outcome following successful PCI.Methods: Between March 2006 and August 2008, 3948 patients underwent successful elective PCI in Tehran Heart Center, Tehran, Iran, and were retrospectively included in this study. Patients who underwent PCI on the same day as the occurrence of myocardial infarction were excluded. The demographic, procedural, in-hospital, and follow-up information of these patients was extracted from the PCI Data Registry of our institution. The patients were divided into three groups:  normal weight (No. 1058, BMI < 25 kg/m2 age = 58 ± 10 years; overweight (No. 1867, 25 ≤ BMI < 30 kg/m2, age = 57 ± 10 years; and obese (No. 1023, BMI ≥ 30 kg/m2, age = 56 ± 10 years. MACE included death, myocardial infarction, target vessel revascularization, and target lesion revascularization.Results: Compared with the other patients, the obese individuals were significantly younger and more frequently female, had a higher ejection fraction, and more frequently presented with hypertension, diabetes, and hyperlipidemia. There was no association between the BMI and the angiographic and procedural findings in the univariate analysis. While no difference was found in the rate of in-hospital death between the groups, the number of the obese patients undergoing emergent cardiac surgery was marginally different in the univariate analysis (p value = 0.06. At 9 months' follow-up, MACE had occurred in 92 (2.3% patients and cardiac mortality was 9 (0.2%. After adjustments for confounders, no significant difference was observed in terms of MACE between the BMI groups.Conclusion: The BMI had no significant effect on the rate of MACE at 9 months' follow-up in our study population.

    Minimizing the catheter size can reduce vascular access complications and contrast dye usage in coronary angiography. The small diameter of the 4Fr guiding catheter has limited the use of several angioplasty devices such as intravascular ultrasound (IVUS) in the past. However, the combination of a novel IVUS catheter and a 0.010 guidewire makes it possible to perform IVUS-guided percutaneous coronary intervention (PCI) with a 4Fr guiding catheter. We herein report the case of a 51-year-old man with silent myocardial ischemia who underwent IVUS-guided transradial PCI with a 4Fr guiding catheter.

    The purpose of this article is to present the results of connecting the interventional radiology and cardiology laboratories of five university hospitals to a unique server using an automatic patient dose registry system (Dose On Line for Interventional Radiology, DOLIR) developed in-house, and to evaluate its feasibility more than a year after its introduction. The system receives and stores demographic and dosimetric parameters included in the MPPS DICOM objects sent by the modalities to a database. A web service provides a graphical interface to analyse the information received. During 2013, the system processed 10 788 procedures (6874 cardiac, 2906 vascular and 1008 neuro interventional). The percentages of patients requiring clinical follow-up due to potential tissue reactions before and after the use of DOLIR are presented. The system allowed users to verify in real-time, if diagnostic (or interventional) reference levels are fulfilled. (authors)

    Independent predictors of death and death or myocardial infarction (MI) during initial hospitalization of patients with acute coronary syndromes (ACS) were determined using database of Russian independent ACS registry RECORD. These predictors (admission Killip class II, ST-segment elevation 1 mm, systolic blood pressure 100 mm Hg, hemoglobin <110 g/L, age 65 years, history of diabetes) were attributed equal weight (1 point) and combined in a prognostic scale for assessment of risk of inhospital death and death or MI. The scale did not include markers of necrosis, and the most time consuming component was measurement of hemoglobin. Sensitivity and specificity of risk scores for prediction of death were 78.5%. The use of GRACE score in this group of patients gave similar results. These preliminary data require confirmation on larger populations of patients with ACS.

    We explored 12-month clinical outcomes of 929 patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with bare-metal stents (BMS) vs. drug-eluting stents (DES) from the prospective multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry. METHODS AND RESULTS: Endpoints included the first occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), target vessel revascularization, definite/probable stent thrombosis (ST), transient ischemic attack or stroke. Bleeding events were defined according to the Bleeding Academic Research Consortium criteria. Altogether, 673 (72.4%) patients received BMS and 220 (23.7%) at least one DES. Patients treated with DES more often had diabetes and prior ischemic events, and a longer stent length (Pheart failure and were more likely to present with acute ST-elevation MI (P<0.05 for both). At 12-month follow-up, rates and risks of MACCE and total bleeding events were comparable between the groups (22.0% with BMS vs. 19.5% with DES, P=0.51, hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.63-1.25 for DES) and (19.5% vs. 15.0%, respectively, P=0.16, HR 0.75, 95% CI 0.51-1.09 for DES). Definite/probable ST was more frequent in the BMS group (1.9% vs. 0%, respectively, P=0.046). In real-world patients with AF undergoing PCI, DES use was associated with outcomes comparable to those with BMS without excess bleeding complications. More ST was seen in BMS-treated patients.

    Percutaneous coronary intervention (PCI) is the most effective reperfusion modality in patients with acute myocardial infarction (MI). Data concerning long-term survival and functional outcome are sparse. One thousand consecutive patients treated by emergency PCI were systematically ana-lysed in a single-centre registry. Multivariate predictors of in-hospital mortality, post-discharge mortality and late functional capacity were identified. Follow-up was completed for 978 patients. The median clinical follow-up length was 3.2 years. In-hospital and post-discharge mortality were 7.6% and 7.3%, respectively. Annualised post-discharge mortality remained stable over time at 2% per year. Independent predictors of in-hospital death were cardiogenic shock, TIMI flow 6 h. Independent predictors of post-discharge mortality were TIMI flow after PCI <3, prior MI, elevated glucose levels at admission, and increasing age. In contrast, cardiogenic shock, time to patent artery and left ventricular ejection fraction <40% were not independently associated with post-hospital death. At late follow-up, 47% of patients had normal functional capacity and 49.1% were in New York Heart Association functional class II. Predictors of impaired functional capacity at follow-up were age, gender, smoking habits and multivessel coronary disease. Post-discharge mortality after PCI for acute MI was 2% per year. Significant differences exist between predictors of in-hospital and post-discharge mortality. The functional capacity of surviving patients was remarkably good, even when presented in cardiogenic shock.

    Numerous studies have reported the relationship between elevated homocysteine (Hcy) levels and the risk of coronary artery disease. However, there is insufficient information about the effects of Hcy levels on long-term clinical outcomes in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). In the Juntendo-registry cohort from 2003 to 2004, pre-procedural Hcy levels and Hcy thiolactonase activity (HTlase) were measured in 315 consecutive all-comer patients who underwent PCI for stable coronary artery disease or acute coronary syndrome (ACS). Receiver-operating characteristic (ROC) curves were created to assess the optimal cut-off values of Hcy and HTlase. Multivariable Cox proportional hazard regression analysis was used to identify the predictors of clinical outcome. The primary endpoint was all-cause mortality. The patients' mean age was 66±9 years, and 82.5% were males. The median follow-up period was 10.5 years, and overall mortality was 24.5% (73 deaths). On ROC analysis, the optimal cut-off values of Hcy and HTlase were 13.5μmol/L and 230IU/L, respectively. Kaplan-Meier survival analysis showed associations of both higher Hcy levels and lower HTlase activity with worse prognosis (both log-rank p<0.001). On multivariate Cox proportional hazard regression analysis, higher Hcy was strongly associated with the primary outcome, and the adjusted hazard ratio was 3.3 (95% confidence interval, 1.8-5.6; p<0.001). Pre-procedural high Hcy levels and low HTlase activity were associated with worse long-term mortality in Japanese patients undergoing PCI. Moreover, Hcy levels are strongly predictive for mortality, independent of traditional risk factors. This may have implications for risk stratification and the therapeutic approach in this PCI era.

    2006-01-01

    Selective coronary angiography and intervention with injection of contrast medium into the coronary arteries has become very common in dealing with coronary cardiac diseases. The excretion of contrast medium through kidneys may lead to acute renal functional insufficiency, especially for those suffering from chronic nephropathy, diabetes and cardiac functional disorder to form the so called 'contrast medium nephropathy' which is considered as the number second drug induced acute renal functional failure. Although routine preventive measure including low osmotic contrast medium and fine hydrotherapy have been taken, 14% incidences still occur with renal functional damage. The majority could be reversible but the minority needs emergent hemodialysis or even with persistent renal functional damage in a few ones. (authors)

    Full Text Available Intraventricular septum-hematoma is a rare complication following percutaneous coronary intervention (PCI. This complication may represent a challenge for accurate diagnosis and treatment. This case report is about a 60-year-old male patient being admitted with an acute coronary syndrome. Despite successful PCI with drug eluting stent implantation into the right coronary artery (RCA the patient complained about recurrent angina pectoris according to Canadian Cardiovascular Society (CCS class IV. Cardiac magnetic resonance imaging and transthoracic echocardiography revealed a massive 4.9×9.2 cm sized end-diastolic septum-hematoma, which compromised right ventricular cavity. Emergent recoronary angiography ruled out further contrast extravasation from the RCA. Conservative treatment was intended after discussion in the “heart-team.” The patient completely recovered with nearly complete resolution of the hematoma after 6 months.

    To assess the long-term results of interventional treatment of diabetic foot using mixed coronary and peripheral equipments and techniques. The interventional diabetic foot syndrome treatment is rapidly becoming the therapy of choice in such patients, but proper materials and techniques are still debated. From January 2006 to December 2010, we prospectively enrolled 220 diabetic patients (78.5 ± 15.8 years, 107 females, all with Fontaine III or IV class), referred to our center for diabetic foot syndrome and severe limb ischemia. Mixed coronary and peripheral guidewires and balloons techniques were used. Doppler ultrasonography and foot transcutaneous oxygen pressure (TCPO2) before and after the procedure were calculated as well as the amputation rate. The preferred approach was ipsilateral femoral antegrade in 170/220 patients (77.7%), contralateral cross-over in 40/220 patients (18.8%), and popliteal retrograde + femoral antegrade in 10/220 patients (4.5%). The techniques included combined use of coronary and dedicated peripheral guidewires and coronary and peripheral dedicated balloons. Balloon angioplasty was performed in 252 legs (32 patients with bilateral disease): the procedure was successful in 239/252 legs with an immediate success rate of 94.8% and a significant improvement in TCPO2 and ankle-brachial index with ulcer healing in 233/252 legs (92.4%). The freedom from major amputation was 82.8% at a mean follow-up of 3.1 ± 1.8 years (range 1 to 5 years). The endovascular diabetic foot syndrome treatment using mixed coronary and peripheral materials and techniques seems to lead to high immediate success and limb salvage rates compared to historical series. ©2011, Wiley Periodicals, Inc.

    The aim of this study was to determine and localize culprit lesion by myocardial perfusion imaging (MPI) in cases of angiographically detected coronary narrowing >or= 75% of at least one coronary artery. One hundred and thirty-two (132) patients with angiographically detected significant coronary narrowing (>or= 75% luminal stenosis of at least one major coronary artery) were studied. All the patients submitted MPI (99m)Tc-MIBI, with pharmacologic dipyridamole stress protocol with concomitant low level bicycle exercise 50W (DipyEX). We measured relative uptake (99m)Tc-MIBI for each myocardial segment using short-axis myocardial tomogram study. A 5-point scoring system was used to assess the difference between uptake degree in stress and rest studies for the same segments, and we created two indices: Sum reversibility score (SRS), Index of sum reversibility score (ISRS). A total of 396 vascular territories (2244 segments) were analyzed before elective percutaneous coronary intervention (ePCI). Overall sensitivity, specificity and accuracy using SRS were 90.2%, 87.5%, and 89.4%, with a positive predictive value of 94.1%. Overall sensitivity, specificity, and accuracy using ISRS were 94.4%, 90.6%, 93.2% and the positive predictive value was 95.7%. DipyEX MPI with the two indices created, SRS and ISRS, significantly improves sensitivity, specificity and accuracy in the determination and localization of culprit lesions in patients undergoing elective PCI.

Revascularization either with Primary Percutaneous Coronary Intervention (PCI or pharmacological therapy is an optional treatment for ST Elevation Acute Coronary Syndrome (STEACS patients. The aim of the study was to compare the functional capacity using six-minute walking test on STEACS patients who underwent Primary PCI or pharmacological therapy. Methods: A cross sectional study was conducted from September to October 2012 to 35 STEACS patients who were treated after two years. The samples were obtained from the list of patients at Dr. Hasan Sadikin General Hospital. Inclusion criteria consisted of patients diagnosed as STEACS, cooperative and not experiencing cognitive disturbance. The exclusion criteria were STEACS patients with unstable angina or myocardial infarct in the last month, stable exertional angina, and pregnant women. The patients underwent 6 minutes walking test,VO2max was measured using theCalahin and Cooper formula, then Metabolic Equation Task (METs was calculated. Data were analyzed by unpaired T-test. Results: There were 19 Primary PCI and 16 pharmacological therapy patients. The average of age between the two groups was distributed evenly. Most of the STEACS patients were male, had a college/academic degree and were retired. Patients treated with pharmacological therapy had higher average of VO2 max and METs than patients with Primary PCI. There was no significantly differences of METs between those groups (p>0.05 Conclusions: There were no significantly differences of functional capacity in STEACS patients treated with Primary PCI or Pharmacological therapy.

    Background The impact of operator experience on fluoroscopy time and contrast utilization during percutaneous coronary intervention (PCI) of coronary chronic total occlusions (CTOs) has received limited study. Methods We evaluated temporal trends in fluoroscopy time and contrast utilization among 1,363 consecutive CTO PCIs performed at 3 US institutions between January 2006 and November 2011. Results Mean age was 65±11 years, 85% of patients were men, 40% had diabetes, 37% had prior coronary artery bypass graft surgery and 42% had prior PCI. The CTO target vessel was the right coronary artery (55%), circumflex (23%), left anterior descending artery (21%), and left main or bypass graft (1%). The retrograde approach was used in 34% of all procedures. The technical and procedural success rates were 85.5% and 84.2%, respectively. The mean procedural time, fluoroscopy time and contrast utilization was 113±61 minutes, 42±29 minutes, and 294±158 ml, respectively. Years since initiation of CTO PCI was independently associated with higher technical success rate (OR=1.52, 95% CI 1.52 to 1.70, p fluoroscopy time (OR=0.84, 95% confidence intervals (CI) 0.75 to 0.95, p=0.005) and contrast utilization (OR=0.84, 95% CI 0.62 to 0.79, p fluoroscopy time and contrast utilization paralleled with an improved technical success rate over time.

    The aim of this study was to explore the efficacy and safety of hemodialysis in interventional therapy for patients with coronary artery disease combined with chronic renal insufficiency. With the aging and social development, the number of coronary artery disease patients with chronic renal insufficiency gradually increased. Total 58 coronary heart disease patients with chronic renal dysfunction were selected. These patients were characterized with typical angina symptoms and typical electrocardiogram (ECG) changes of onset angina. Continuous oral administration of sodium bicarbonate tablets 1 g 3/day × 3 days and slow intravenous input sodium chloride 1000 ∼1500 mL 3-12 h before operation were given. By this way, all patients were treated by hydration and alkalization. After percutaneous coronary intervention (PCI) treatment, patients were immediately transferred to undergo 4 h of dialysis treatment without removing indwelling of femoral artery puncture sheath tube to protect renal function. Changes in renal function including serum creatinine, glomerular filtration rate, and urine were observed and recorded. All patients were successfully underwent PCI treatment. Within one month after PCI, there were no obvious complication and no stent thrombosis occurred. Among of 58 patients, 56 cases showed no significant increase in serum creatinine levels compared with those before operation. However, serum creatinine level of one patient increased to 251 umol/L and one patient still required permanent dialysis. Using hemodialysis in interventional therapy in coronary artery disease patients with chronic renal insufficiency could significantly improve the prognosis of the patients.

    The aim of our study is to assess the feasibility, safety, and rate of radial artery occlusion (RAO) using 7F sheathless guiding catheter in a large population undergoing transradial intervention (TRI). There is a frequent need for large bore guiding catheter to perform complex coronary interventions. Hydrophilic sheathless guiding catheters are not available in the US, therefore, we present the results of a multicenter study using the modified sheathless technique and readily available catheters. Between December 2010 and February 2011, 116 consecutive patients from four tertiary US centers who underwent TRI using 7F sheathless guiding catheter were included in this study. In our study of 116 patients with 123 coronary lesions, 57 stenoses (49%) were complex interventions, which included patients with acute coronary syndromes, chronic total occlusion (CTO), bifurcation stenting, calcified lesions, left main artery, and saphenous venous graft interventions. Overall procedural success rate was 95%. At 7-day, there were six patients (5%) with RAO, of which two of the six had severe radial artery spasm during the procedure. At 30-day, the overall persistent RAO was only detected in three patients (2.5%), as three patients had return of antegrade radial artery flow. In our multicenter study of 116 consecutive patients, using 7F sheathless guiding catheter to perform TRI is associated with a high procedural success (95%) and a low 30-day RAO rate (2.5%).

    Dipyridamole-loading 99m Tc-tetrofosmin myocardial scintigraphy was performed for patients with coronary artery disease who underwent percutaneous transluminal coronary angiography (PTCA) in order to examine whether SPECT imaging prior to treatment is useful for the determination of prognosis after coronary intervention. Thirty-six patients including 9 with angina pectoris (AP), 22 with old myocardial infarction (OMI) and 5 OMI with AP were underwent dipyridamole-loading 99m Tc-tetrofosmin myocardial SPECT before and after coronary intervention. The length of follow-up was 185±107 days after PTCA. Improvement of myocardial uptake was observed on myocardial SPECT in all cases with AP. Improvement of the myocardial uptake was observed 50% (4/8) of patients with OMI who had no myocardial viability. It was suggested that the improvement of myocardial uptake after PTCA was due to incomplete fill-in in cases with AP and that presence of fill-in was important for level of fill-in in patients with AP. The improvement of myocardial uptake in the scar tissue in patients with OMI contributed to the hibernating myocardium. We concluded that correct detection of hibernating myocardium was difficult despite the superior imaging capacity of 99m Tc-tetrofosmin myocardial SPECT. (author)

    To observe the effects of different loading doses of atorvastatin calcium on the outcomes of percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease (CHD). A total of 120 CHD patients aged over 80 years were randomly assigned into 3 equal groups to receive intensive pretreatment with statin at the doses of 20, 40, or 60 mg prior to PCI performed within 48 to 72 h after admission. The changes of postoperative cardiac biochemical markers including creatine kinase isoenzyme (CKMB), troponin I (cTNI) and high-sensitivity c-reactive protein (hs-CRP) were observed and the incidence of major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization) were recorded within 30 days after PCI. Thirty-four patients in 20 mg statin group, 40 in 40 mg statin group, and 38 in 60 mg statin group completed this study. In all the 3 groups, hs-CRP level significantly increased at 12 and 24 h after PCI compared with the preoperative levels (P0.05). Intensive pretreatment with 60 mg/day atorvastatin calcium can significantly reduce myocardial infarction related to PCI with good safety in elderly patients with CHD.

    Traditional prognostic risk assessment in patients undergoing non-invasive imaging is based upon a limited selection of clinical and imaging findings. Machine learning (ML) can consider a greater number and complexity of variables. Therefore, we investigated the feasibility and accuracy of ML to predict 5-year all-cause mortality (ACM) in patients undergoing coronary computed tomographic angiography (CCTA), and compared the performance to existing clinical or CCTA metrics. The analysis included 10 030 patients with suspected coronary artery disease and 5-year follow-up from the COronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter registry. All patients underwent CCTA as their standard of care. Twenty-five clinical and 44 CCTA parameters were evaluated, including segment stenosis score (SSS), segment involvement score (SIS), modified Duke index (DI), number of segments with non-calcified, mixed or calcified plaques, age, sex, gender, standard cardiovascular risk factors, and Framingham risk score (FRS). Machine learning involved automated feature selection by information gain ranking, model building with a boosted ensemble algorithm, and 10-fold stratified cross-validation. Seven hundred and forty-five patients died during 5-year follow-up. Machine learning exhibited a higher area-under-curve compared with the FRS or CCTA severity scores alone (SSS, SIS, DI) for predicting all-cause mortality (ML: 0.79 vs. FRS: 0.61, SSS: 0.64, SIS: 0.64, DI: 0.62; PMachine learning combining clinical and CCTA data was found to predict 5-year ACM significantly better than existing clinical or CCTA metrics alone.

    In patients with suspected acute coronary syndrome, a new or presumably new left bundle branch block (LBBB) does not always imply ST-segment elevation myocardial infarction (STEMI). We aimed to show the low frequency of STEMI-equivalent in this population and determine the diagnostic value of electrocardiographic and echocardiographic features. From the 387 patients captured by the Louisiana State University code STEMI registry between 2009 and 2012, we examined data on 26 patients with LBBB. These patients were divided into 3 groups according to the final diagnosis: (1) STEMI-equivalent, defined as an acute coronary occlusion on angiography (2 patients), (2) non-ST-segment elevation myocardial infarction (4 patients), and (3) diagnoses other than myocardial infarction (non-MI) (20 patients). Troponin elevation and left ventricular systolic dysfunction were common in all 3 groups (non-significant p-values). Compared with non-MI patients, patients with STEMI-equivalent had a larger degree of ST-segment discordance and T-wave discordance, as assessed by ST/QRS and T/QRS ratios (pdiagnosis of STEMI-equivalent in the setting of LBBB. Conversely, absolute values of ST-segment and T-wave discordance were not significantly different between groups. ST-segment concordance was highly specific for the diagnosis of STEMI-equivalent, but had a limited sensitivity. Only a minority of patients with suspected acute coronary syndrome and LBBB have a STEMI-equivalent. Excessive relative discordance of the ST segment or the T wave appears predictive of STEMI-equivalent, but this is only hypothesis-generating considering the small population size.

    The mainstay of cholesterol reduction therapy is the diet. But the lack of compliance and prescription problems limit its usefulness. To compare the effectiveness of a nutritional intervention given by a nutritionist with the usual recommendations given by a physician to reduce the LDL cholesterol levels in patients with coronary artery disease, treated at the Regional public hospital in Temuco. One hundred and forty patients with coronary heart disease (last acute episode at least three months before), without nutritional interventions nor cholesterol-lowering drugs, who gave informed consent, were randomized to receive either instructions by their physician or to take part in a nutritional program. The nutritional intervention consisted in five educational sessions, adapted from the NCEP and from a program of the Nutrition Department of the Catholic University of Chile. Patients randomized to the medical intervention received the standard written recommendations about diet. Lipid profile was measured before the intervention and after a three and twelve months follow up. After one year the group on the nutritionalprogram reduced LDL cholesterol by 11.1% (p=0.03). There were no changes in the medical group. However, only 10% patients on the nutritional intervention group and 8% of those with medical recommendations achieved LDL cholesterol levels less than 100 mg/dl. There were no changes in triglycerides, weight or body mass index during the period. Although this nutritional intervention proved to be more effective than usual medical instructions, most patients on secondary prevention did not achieve acceptable LDL cholesterol levels.

    Guidelines for patients with ST-elevation myocardial infarction include a door-to-balloon time (DTBT) of ≤90 min for primary percutaneous coronary intervention. The aim of this study was to assess temporal trends (2006-2010) in DTBT and determine if a reduction in DTBT was associated with improved clinical outcomes. We compared annual median DTBT in 1926 STEMI patients undergoing primary percutaneous coronary intervention from the Melbourne Interventional Group registry. ST-elevation myocardial infarction presenting >12 h and rescue percutaneous coronary intervention was excluded. Major adverse cardiac events were analysed according to DTBT (dichotomised as ≤90 min vs >90 min). A multivariable analysis for predictors of mortality (including DTBT) was performed. Baseline demographics, clinical and procedural characteristics were similar in the STEMI cohort across the 5 years, apart from an increase in out-of-hospital cardiac arrest (3.6% in 2006 vs 9.4% in 2010, P < 0.0001) and cardiogenic shock (7.7-9.6%, P = 0.07). The median DTBT (interquartile range) was reduced from 95 (74-130) min in 2006 to 75 (51-100) min in 2010 (P < 0.01). In this period, the proportion of patients achieving a DTBT of ≤90 min increased from 45% to 67% (P < 0.01). Lower mortality and major adverse cardiac event rates were observed with DTBT ≤90 min (all P < 0.01). Multivariable analysis showed that a DTBT of ≤90 min was associated with improved clinical outcomes at 12 months (odds ratio 0.48; 95% confidence interval 0.33-0.73, P < 0.01). There has been a decline in median DTBT in the Melbourne Interventional Group registry over 5 years. DTBT of ≤90 min is associated with improved clinical outcomes at 12 months. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

    The best revascularisation method of the unprotected left main artery is a current and evolving topic. A total of 2439 percutaneous coronary interventions (PCI) were registered during a 3-year period. The study included all the patients with PCI of the unprotected left main coronary (n=48) and matched with patients who underwent coronary artery bypass graft (CABG) (n=50). Major adverse cerebral and cardiac events (MACCE) were assessed within the hospital and in outpatients during a 16 month follow up. The cardiovascular risk was greater in the PCI group; logEuroSCORE 16±21 vs. 5±6, P=.001; clinical Syntax 77±74 vs 53±39, P=.04. On admission, the PCI group of patients had a higher frequency of ST segment elevation myocardial infarction (STEMI) and cardiogenic shock. The MACCE were similar in both groups (14% vs. 18%, P=.64). STEMI was less frequent in the PCI group (0% vs. 10%, P=.03). Cardiovascular events were lower in the PCI group (2.3% vs. 18%, P=.01), and there was a decrease in general and cardiac mortality (2.3% vs. 12%, P=.08 y 2.3% vs. 8%, P=.24), on excluding the patients with cardiogenic shock as a presentation. MACCE were similar in both groups in the out-patient phase (15% vs. 12%, P=.46). Survival without MACCE, general and cardiac death were comparable between groups (log rank, P=.38, P=.44 and P=.16, respectively). Even though the clinical and peri-procedural risk profile of the PCI patients were higher, the in-hospital and out-hospital efficacy and safety were comparable with CABG.

    2008-06-01

    Full Text Available Contrast induced nephropathy (CIN is one of important complication of contrast media administration. Its incidence and risk factors among Indonesian patients undergoing coronary intervention has not been reported yet. CIN was defined as increasing of serum creatinine by 0.5 mg/dl or more in the third day following contrast media exposure. Of 312 patients undergoing coronary intervention, 25% developed CIN. Patient-related risk factors comprised of hypertension, diabetes mellitus, NYHA class, proteinuria, serum creatinine > 1.5 mg/dl and ejection fraction ≤ 35%. Contrast-related risk factors comprised of contrast media volume > 300 ml, contrast media type. However, our final model demonstrated that only hypertension [Hazard ratio (HR = 2.89, 95% confidence intrval (CI = 1.78 to 4.71, P = 0.000], diabetes mellitus (HR = 3.09, 95% CI = 1.89 to 5.06, P = 0.000, ejection fraction (EF ≤ 35% (HR = 2.92; 95% CI = 1.72 to 4.96; P = 0.000, total contrast volume > 300 ml (HR = 7.73; 95% CI = 3.09 to 19.37; P = 0.000 and proteinuria (HR = 14.96; 95% CI = 3.45 to 64.86; P = 0.000 were independent risk factors of CIN. In conclusion, CIN developed in 25% of patients undergoing coronary intervention. The independent risk factors of CIN included hypertension, diabetes mellitus, EF ≤ 35%, contrast volume > 300 ml and proteinuria.

    Current guidelines have recommended against coronary revascularization before noncardiac surgery in patients with asymptomatic coronary artery disease. However, myocardial infarction after thoracic aneurysm (TA) repair dramatically increases the morbidity and mortality. Revascularization with coronary artery bypass grafting before TA repair minimizes the incidence of perioperative ischemia. However, the recovery can be prolonged, and a percentage of patients will either never return for aneurysm repair or will develop a rupture during convalescence. Percutaneous coronary intervention (PCI) before TA repair might be preferable. Previous studies examining PCI before major vascular surgery included few patients with TAs. We examined the outcomes of patients undergoing PCI before TA repair. From 1997 to 2012, 592 patients underwent TA repair. Patients presenting for elective repair underwent cardiac catheterization before surgery. Those with significant single- or double-vessel coronary artery disease underwent PCI. The perioperative outcomes were examined and compared with those of patients undergoing TA repair without revascularization. A total of 44 patients (7.4%) underwent PCI with bare metal stents before surgery. No PCI-related complications occurred. Dual antiplatelet therapy was administered for 4 to 6 weeks. No instances of aneurysm rupture occurred in the interval between PCI and surgery. The incidence of stent thrombosis, myocardial infarction, and mortality for those undergoing PCI was 0. No bleeding complications occurred. PCI is safe and efficacious in patients undergoing TA repair. Aneurysm rupture did not occur in the interval before surgery. Antiplatelet therapy did not increase the risk of bleeding complications. Stent thrombosis was not seen. We recommend PCI those with significant single- or double-vessel coronary artery disease before elective TA repair. Copyright © 2014 The American Association for Thoracic Surgery.

    To evaluate the effects of sex and anthropometry on clinical outcomes in patients who underwent percutaneous coronary intervention (PCI). From three randomized trials (REal Safety and Efficacy of 3-month dual antiplatelet Therapy following Endeavor zotarolimus-eluting stent implantation, Impact of intraVascular UltraSound guidance on outcomes of Xience Prime stents in Long lesions, Chronic Total Occlusion InterVention with drUg-eluting Stents), we compared 333 pairs of men and women matched by propensity scores, all of whom underwent intravascular ultrasound (IVUS)-guided PCI for complex lesions. For 12 months, the incidence of adverse cardiac events, defined as the composite of cardiac death, target lesion-related myocardial infarction, and target lesion revascularization, was not different between women and men (2.4% vs. 2.4%, p=0.939). Using multivariable Cox's regression analysis, post-intervention minimum lumen area [MLA; hazard ratio (HR)=0.620, 95% confidence interval (CI)=0.423-0.909, p=0.014] by IVUS was a predictor of adverse cardiac events. Height on anthropometry and lesions with chronic total occlusion were significantly related to post-intervention MLA. However, female sex was not independently associated with post-intervention MLA. In an age and sex-adjusted model, patients in the low tertile of height exhibited a greater risk for adverse cardiac events than those in the high tertile of height (HR=6.391, 95% CI=1.160-35.206, p=0.033). Sex does not affect clinical outcomes after PCI for complex lesions. PCI outcomes, however, may be adversely affected by height.

    The aim of this study is to assess the factors associated with self-care agency in postpercutaneous coronary intervention patients. Patients after percutaneous coronary intervention need to perform self-care to reduce the side effects and increase the quality of life. Self-care agency is considered to be an important factor in guaranteeing self-care actions. In this descriptive study a total number of 300 postpercutaneous coronary intervention patients participated. Data were collected from the four hospitals affiliated with Shahid Beheshti University of Medical Sciences in Iran between February-May 2015. The data were gathered using demographic and basic conditioning factors questionnaire and appraisal of self-care agency scale. Data analysis was performed by anova and t-test. The mean age of the participants was 62·10 ± (8·14), which included 52·7% men and 47·3% women. Most patients (72%) had good level of self-care agency. Self-care agency had higher level in married and higher income patients. Self-care agency is influenced by economic and marital situation. Identifying factors associated with self-care agency can help healthcare professionals to consider these factors in self-care planning. © 2016 John Wiley & Sons Ltd.

    Fractional flow reserve (FFR) is not firmly established as a guide to treatment in patients with acute coronary syndromes (ACS). Primary goals were to evaluate the impact of integrating FFR on management decisions and on clinical outcome of patients with ACS undergoing coronary angiography, as compared with patients with stable coronary artery disease. R3F (French FFR Registry) and POST-IT (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease), sharing a common design, were pooled as PRIME-FFR (Insights From the POST-IT and R3F Integrated Multicenter Registries - Implementation of FFR in Routine Practice). Investigators prospectively defined management strategy based on angiography before performing FFR. Final decision after FFR and 1-year clinical outcome were recorded. From 1983 patients, in whom FFR was prospectively used to guide treatment, 533 sustained ACS (excluding acute ST-segment-elevation myocardial infarction). In ACS, FFR was performed in 1.4 lesions per patient, mostly in left anterior descending (58%), with a mean percent stenosis of 58±12% and a mean FFR of 0.82±0.09. In patients with ACS, reclassification by FFR was high and similar to those with non-ACS (38% versus 39%; P =NS). The pattern of reclassification was different, however, with less patients with ACS reclassified from revascularization to medical treatment compared with those with non-ACS ( P =0.01). In ACS, 1-year outcome of patients reclassified based on FFR (FFR against angiography) was as good as that of nonreclassified patients (FFR concordant with angiography), with no difference in major cardiovascular event (8.0% versus 11.6%; P =0.20) or symptoms (92.3% versus 94.8% angina free; P =0.25). Moreover, FFR-based deferral to medical treatment was as safe in patients with ACS as in patients with non-ACS (major cardiovascular event, 8.0% versus 8.5%; P =0.83; revascularization, 3.8% versus 5.9%; P =0.24; and freedom from angina, 93.6% versus 90.2%; P =0

    Bioresorbable scaffolds (BRS) represent a novel paradigm in the 40-year history of interventional cardiology. Restoration of cyclic pulsatility and physiologic vasomotion, adaptive vascular remodeling, plaque regression, and removal of the trigger for late adverse events are expected BRS benefits over current metallic drug-eluting stents. However, first-generation BRS devices have significant manufacturing limitations and rely on optimal implantation technique to avoid experiencing an excess of clinical events. There are currently at least 22 BRS devices in different stages of development, including many trials of device iterations with thinner (BRS. This article reviews the outcomes of commercially available and potentially upcoming BRS, focusing on the most recent stages of clinical development and future directions for each scaffold type.

    The association between low socioeconomic status (SES) and high mortality from coronary heart disease is well-known. However, the role of SES in relation to the clinical outcome after primary percutaneous coronary intervention remains poorly understood. We studied 7385 patients treated with primary percutaneous coronary intervention. Participants were divided into high-SES and low-SES groups according to income, education, and employment status. The primary outcome was major adverse cardiac events (cardiac death, recurrent myocardial infarction, and target vessel revascularization) at maximum follow-up (mean, 3.7 years). Low-SES patients had more adverse baseline risk profiles than high-SES patients. The cumulative risk of major adverse cardiac events after maximum follow-up was higher among low-income patients and unemployed patients compared with their counterparts (income: hazard ratio, 1.68; 95% CI, 1.47-1.92; employment status: hazard ratio, 1.75; 95% CI, 1.46-2.10). After adjustment for patient characteristics, these differences were substantially attenuated (income: hazard ratio, 1.12; 95% CI, 0.93-1.33; employment status: hazard ratio, 1.27; 95% CI, 1.03-1.56). Further adjustment for admission findings, procedure-related data, and medical treatment during follow-up did not significantly affect the associations. With education as the SES indicator, no between-group differences were observed in the risk of the composite end point. Even in a tax-financed healthcare system, low-SES patients treated with primary percutaneous coronary intervention face a worse prognosis than high-SES patients. The poor outcome seems to be largely explained by differences in baseline patient characteristics. Employment status and income (but not education level) were associated with clinical outcomes.

    The aim of this study was to evaluate changes in three-dimensional (3D) speckle-tracking-derived myocardial strain during ischemia. Twenty patients referred for percutaneous coronary intervention were studied (mean age, 65 ± 11 years; mean left ventricular ejection fraction, 56 ± 7%). Of the 20 study patients, 12 had severe left anterior descending coronary artery stenosis. A full-volume apical view using multibeat 3D modality and two-dimensional (2D) apical views (four chamber, two chamber, and three chamber) were recorded during coronary occlusion before wall motion abnormalities. After percutaneous coronary intervention, ultrasound contrast agent was selectively delivered through the target lesion to delineate ischemic and peri-ischemic segments (ischemia-adjacent segments). Strain values derived from 2D and 3D speckle-tracking echocardiography were compared in ischemic and nonischemic segments. Despite no changes in wall motion and 2D left ventricular ejection fraction (56 ± 7% vs 56 ± 7%), global longitudinal strain by 2D imaging was impaired during percutaneous coronary intervention (-16 ± 3% vs -14 ± 3%, P = .01). Similar changes were observed for all 3D strain components: -11 ± 16% for longitudinal (-15 ± 4% vs -13 ± 4%, P = .03), -13 ± 25% for circumferential (-15 ± 4% vs -12 ± 4%, P = .02), -12 ± 16% for area (-25 ± 5% vs -22 ± 6%, P = .009), and -12 ± 25% for radial global strain (39 ± 12% vs 33 ± 12%, P = .04). During coronary occlusion, 2D longitudinal peak strain and all 3D peak strain components decreased in ischemic segments, while no changes was observed in nonischemic segments. In peri-ischemic segments, only 3D longitudinal and area strain were impaired during ischemia. Changes in myocardial deformation related to ischemia can be characterized by 3D speckle-tracking echocardiography before the stage of wall motion abnormality. Copyright © 2013 American Society of

    Our aim was to evaluate the feasibility and safety of routine transradial approach (TRA) percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions using the sheathless technique with standard guiding catheters. Transradial approach PCI was applied for CTO lesions. A major limitation of TRA CTO PCI is the inability to use large guiding catheters because of the relatively small size of the radial artery. Therefore, the sheathless technique for TRA PCI has been recently developed. However, reports on TRA CTO PCI using the sheathless technique are still lacking. Sixty-eight patients with CTO lesions were enrolled for TRA PCI using the sheathless technique with standard guiding catheters. The baseline characteristics, coronary angiographic characteristics and major procedure or access site related complications were compared between procedure success and procedure failure group to determine the predictors of success in sheathless CTO PCI. In-hospital and 30-day clinical outcomes were also evaluated in this study. Routine assessments of radial artery occlusion via Doppler ultrasound and pulse oximeter were recorded during one-year clinical follow-up. The mean duration of CTO by history was 31.8 ± 42.3 months. The 7 Fr standard guiding catheter was used with the sheathless technique in 91.2%, and bilateral sheathless approach in 42.6% of the study patients. The procedure-related complications included coronary perforation needing covered stent deployment (2.9%), cardiac tamponade (2.9%), collateral perforation needing coil deployment (4.4%), and contrast induced nephropathy (2.9%). Only 2 patients (2.9%) experienced forearm ecchymosis at the radial artery access sites. In-hospital mortality and 30-day all-cause mortality were 2.9%, and 30-day MACEs were 1.5%. The rate of radial artery occlusion during one-year clinical follow-up was only 3.0%. It is feasible and safe to routinely use the sheathless technique with standard guiding catheters for

    Full Text Available The impact of left ventricular hypertrophy (LVH on survival among patients with established coronary artery disease (CAD is not well understood. We sought to evaluate the effect of LVH on the survival of patients with CAD following percutaneous coronary intervention (PCI. Three hospitals in New York City contributed prospectively defined data on 4284 consecutive patients undergoing PCI. All-cause mortality at a mean follow-up of three years was the primary endpoint. LVH was present in 383 patients (8.9%. LVH patients had a greater prevalence of hypertension (88% vs. 68%, p<0.001, vascular disease (21% vs. 6.6%, p=0.001, and prior heart failure (10% vs. 5.5%, p<0.001. LVH patients presented less often with one-vessel disease (38% vs. 50%, p=0.040 and more often with two- (34% vs. 29%, p=0.014 or three-vessel (22% vs. 18%, p=0.044 disease. Ejection fractions and angiographic success were similar in both groups. In-hospital mortality did not differ between groups. At three-year follow-up, the survival rate for patients with LVH was 86% vs. 91% in patients without LVH (log-rank p=0.001. However, after adjustment for differences in baseline characteristics using Cox proportional hazards analysis, LVH was found not to be an independent predictor of mortality (hazard ratio, 0.93; 95% confidence interval, 0.68-1.28; p=0.67. We conclude that LVH at the time of PCI is not independently associated with an increase in the hazard of death at three years.

    Mean platelet volume (MPV) is a well-established marker of platelet activation, and recent studies have shown that platelet activation is central to the processes in the pathophysiology of coronary artery disease (CAD). The study population consisted of 45 patients with stable CAD who underwent successful percutaneous coronary intervention (PCI) with drug-eluting stents. We selected 45 age- and sex-matched control subjects without cardiovascular diseases who did not require antiplatelet therapy. Hematological test was performed 3 times within 1 month before DAPT (baseline), at 2 weeks after PCI (post PCI) and at 9 months after PCI (follow-up). Compared to control subjects, MPV was significantly larger in patients with CAD (10.0 ± 0.6 vs 10.7 ± 0.8 fl, p < 0.01) although there was no significant difference in white blood cell count, hemoglobin, and platelet count between the 2 groups. In patients with CAD, DAPT did not affect platelet count (19.3 ± 4.8 × 10(4)-18.9 ± 4.6 × 10(4)/μl) or MPV (10.7 ± 0.8-10.5 ± 0.9 fl) during the follow-up period. MPV remained to be higher at follow-up in patients with CAD despite DAPT compared to control subjects (10.1 ± 0.7 vs 10.5 ± 0.9 fl, p < 0.05). Our data suggested that MPV might not be suitable for monitoring the effects of DAPT on platelet activity in patients with CAD undergoing PCI.

    Little is known in our country about regional differences in the treatment of acute coronary disease. To analyze the behavior regarding the use of demonstrably effective regional therapies in acute coronary disease. A total of 71 hospitals were randomly selected, respecting the proportionality of the country in relation to geographic location, among other criteria. In the overall population was regionally analyzed the use of aspirin, clopidogrel, ACE inhibitors / AT1 blocker, beta-blockers and statins, separately and grouped by individual score ranging from 0 (no drug used) to 100 (all drugs used). In myocardial infarction with ST elevation (STEMI) regional differences were analyzed regarding the use of therapeutic recanalization (fibrinolytics and primary angioplasty). In the overall population, within the first 24 hours of hospitalization, the mean score in the North-Northeast (70.5 ± 22.1) was lower (p Southeast (77.7 ± 29.5), Midwest (82 ± 22.1) and South (82.4 ± 21) regions. At hospital discharge, the score of the North-Northeast region (61.4 ± 32.9) was lower (p Southeast (69.2 ± 31.6), Midwest (65.3 ± 33.6) and South (73.7 ± 28.1) regions; additionally, the score of the Midwest was lower (p region. In STEMI, the use of recanalization therapies was highest in the Southeast (75.4%, p = 0.001 compared to the rest of the country), and lowest in the North-Northeast (52.5%, p regional differences.

    Implementation of interventions designed to improve the quality of medical care often proceeds differently from what is planned. Improving existing conceptual models to better understand the sources of these differences can help future projects avoid these pitfalls and achieve desired effectiveness. To inform an adaptation of an existing theoretical model, we examined unanticipated changes that occurred in an intervention designed to improve reporting of adjuvant therapies for breast cancer patients at a large, urban academic medical center. Guided by the complex innovation implementation conceptual framework, our study team observed and evaluated the implementation of an intervention designed to improve reporting to a tumor registry. Findings were assessed against the conceptual framework to identify boundary conditions and modifications that could improve implementation effectiveness. The intervention successfully increased identification of the managing medical oncologist and treatment reporting. During implementation, however, unexpected external challenges including hospital acquisitions of community practices and practices' responses to government incentives to purchase electronic medical record systems led to unanticipated changes and associated threats to implementation. We present a revised conceptual model that incorporates the sources of these unanticipated challenges. This report of our experience highlights the importance of monitoring implementation over time and accounting for changes that affect both implementation and measurement of intervention impact. In this article, we use our study to examine the challenges of implementation research in health care, and our experience can help future implementation efforts.

    In a ranking of the gross domestic product per capita in 2015, Belgium ranked 19th in the world according to the International Monetary Fun1d and the World Bank. It has a Human Development Index of 0.890, in which it is preceded by only 20 other countries in the world. This is, at least in part, due to a well-developed social security system on which all citizens can rely. Over the last 5-10 years, however, this system has come under increasing pressure. This has resulted in insufficient, incomplete and late reimbursement of all technologies that were introduced over the last ten years in the cathlab: intracoronary imaging techniques are not reimbursed at all, and FFR only to a vastly insufficient degree. For several structural heart interventions, a system of limited and incomplete reimbursement has recently been set up, with a requirement to organise these procedures within the frames of hospital networks. Numbers of PCIs have risen by 15% over the last four years, coinciding with an increase in the number of cathlabs by 50%, aiming at better access to primary PCI for STEMI patients. This has also resulted in a decrease in the average procedure volume per centre. Two thirds of PCIs are performed via the radial access. DES penetration has increased to 74%, approaching 100% in some centres, while the uptake of BRS has been very limited so far.

    To evaluate the target lesion failure (TLF) rate of the SYNERGY stent in all-comers, multiethnic Asian population. Currently, most drug eluting stents deliver anti-proliferative drugs from a durable polymer which is associated with a risk of late stent thrombosis. The novel everolimus-eluting, platinum chromium SYNERGY stent is coated with a bioabsorbable abluminal polymer that resolves within 4 months. This was a prospective, single center registry of consecutive patients treated with the SYNERGY stent between December 2012 and April 2015. The primary outcome was the incidence of TLF, defined as the combination of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization (TLR) at 1 year. A total of 807 patients received the SYNERGY stent during the study period. One-year clinical outcome data was available for 765 patients (94.8%) and were considered for statistical analysis. The mean age was 60.7 ± 10.8 years, and 83.4% were males. Patients with acute myocardial infarction consisted of 50.3% (ST-segment elevation myocardial infarction: 23.0%, Non-ST-segment elevation myocardial infarction: 27.3%) of the study population. The treated lesions were complex (ACC/AHA type B2/C: 72.7%). The primary end point of TLF at 1 year was 5.8%. Rates of cardiac mortality, target vessel myocardial infarction, and TLR were 4.2, 1.0, and 1.3%, respectively, at 1 year. Predictors of the incidence and time to early TLF were female gender, Malay ethnicity, diabetes mellitus, acute myocardial infarction at presentation, a prior history of coronary artery bypass surgery and the presence of lesion calcification. The incidence of definite stent thrombosis was 0.4% at 1 year. In this registry, the use of the SYNERGY stent was associated with low rates of TLF at 1 year. © 2018 Wiley Periodicals, Inc.

    Percutaneous coronary intervention (PCI) is effective therapy for significant atherosclerotic coronary artery disease. Despite medical and technological advances in PCI, periprocedural myocardial infarction (PMI) remains a common complication. The frequency and factors associated with PMI have been well investigated in the developed world, yet there is a paucity of data from the developing world, especially Sub-Saharan Africa. We prospectively enrolled 153 adult patients undergoing PCI at the Charlotte Maxeke Johannesburg Academic Hospital from the 1st of February 2014 to 31st October 2014. Periprocedural Creatinine Kinase-MB and hs-Troponin I were routinely measured before PCI and at 16-24h post-procedure. The third universal definition of myocardial infarction was used to define a PMI event. 152 participants met the inclusion criteria and were analysed for PMI. 70.4% participants were male. The mean age was 58.8 (SD 10.9) years old. Sixteen (10.5%) participants fulfilled the criteria for PMI. Side branch pinching with preserved TIMI III flow was noted in 62.5% of PMI cases. Duration of procedure (P=0.007), right coronary artery intervention (p=0.042) and total stent length (p=0.045) were independently associated with PMI. PMI occurred in 10.5% of cases undergoing PCI. This is consistent with the prevalence of PMI internationally. Larger multicentre studies are required in our demographic region to further define relevant predictors and outcomes associated with PMI. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    In the United Kingdom, a clinical data set is completed for every patient undergoing coronary intervention and certain structural interventions, and sent to central servers in the National Institute for Cardiovascular Outcomes Research (NICOR) on behalf of the British Cardiovascular Intervention Society (BCIS). These data are linked to the national mortality register. In addition, data are obtained about the structure of healthcare provision using an annual survey. Analyses of these data are provided for different audiences in several formats. Public reports of individual consultant operator activity and risk-adjusted outcomes from percutaneous coronary intervention (PCI) have also been produced annually since 2012. Transcatheter aortic valve implantation (TAVI) has been performed since 2007. Over 2,000 cases were performed in 2015, giving a rate of 30 per million population. Complications to discharge have fallen as case mix has changed and technologies improved. While the mean age has remained about 81 years, the logistic EuroSCORE of patients treated by TAVI has fallen from about 22 in 2010 to 18 in 2015. Tracked 30-day mortality was 3.7% in 2014. Left atrial appendage occlusion and patent foramen ovale (PFO) closure for stroke, and the use of the MitraClip® system (Abbott Vascular, Santa Clara, CA, USA) for mitral regurgitation have been funded through a process called "commissioning through evaluation".

    2018-01-01

    Full Text Available Interventional cardiologists have witnessed an explosive growth in the field. A wide array of percutaneous procedures allow us to treat numerous cardiac conditions less invasively. However, the way we work has changed very little over the past decades. We continue to stand at the tableside for prolonged periods of time, exposing ourselves to the very real risks of radiation exposure as well as to the associated orthopedic injuries from radiation protection. The precision of our procedures is limited by the distance from the fluoroscopic images and, furthermore, patients are potentially at risk from operator fatigue caused by a physician standing at the table for prolonged periods while wearing cumbersome radiation protection gear. Robotic-assisted coronary intervention removes the operator from the radiation field and has been shown to markedly reduce operator exposure as well as allow for more precise positioning of balloons and stents. This technology holds great promise for making interventional procedures safer and more comfortable for the operators as well as reducing fatigue, potentially improving patient outcomes. Currently, we are in an ‘early adopter’ phase of this technology and this paper reviews the rationale, methodology, optimal case selection, and limitations of robotic-assisted coronary intervention.

    Disease registries, audit and feedback, and clinical reminders have been reported to improve care processes. To assess the effects of a registry-generated audit, feedback, and patient reminder intervention on diabetes care. Randomized controlled trial conducted in a resident continuity clinic during the 2003-2004 academic year. Seventy-eight categorical Internal Medicine residents caring for 483 diabetic patients participated. Residents randomized to the intervention (n = 39) received instruction on diabetes registry use; quarterly performance audit, feedback, and written reports identifying patients needing care; and had letters sent quarterly to patients needing hemoglobin A1c or cholesterol testing. Residents randomized to the control group (n = 39) received usual clinic education. Hemoglobin A1c and lipid monitoring, and the achievement of intermediate clinical outcomes (hemoglobin A1c audit, feedback, and patient reminder intervention in a resident continuity clinic modestly improved diabetes care processes, but did not influence intermediate clinical outcomes.

    Full Text Available Background The local injection of novel cardioprotective study drugs prior to percutaneous coronary intervention could cause embolisation of thrombus, resulting in increased reperfusion injury and subsequent infarct size. The aim of this study was to assess the safety of the delivery of an intracoronary therapy delivered during primary percutaneous coronary intervention for acute myocardial infarction prior to the re-establishment of thrombolysis in myocardial infarction III flow. Methods One hundred sixty-seven patients with acute myocardial infarction successfully reperfused through primary percutaneous coronary intervention and undergoing Cardiac MRI within the first week after reperfusion were studied. Patients either underwent the delivery of an intracoronary agent (IMP or placebo prior to balloon dilatation ( n  = 80 or standard primary percutaneous coronary intervention procedure ( n  = 117. Results Baseline characteristics were similar between the two groups. There were a similar number of successful procedures (IC IMP 75 (93.8% vs. No IMP 114, (97.4%, p  = 0.374, rates of no-reflow (IC IMP 1 (1.3% vs. No IMP 2 (1.7%, p  = 0.99 and levels of ST segment resolution (88.5% IC IMP vs. No IC IMP 87.0%, p  = 0.669 between the two groups. Similar levels of microvascular obstruction were seen between the two groups with a trend to reduced infarct size, and improved ejection fractions in the IMP group. Lower MACE rates were seen in the IMP group. Conclusion The local intracoronary infusion of potential cardioprotective agents prior to the restoration of TIMI flow in patients undergoing primary percutaneous coronary intervention for acute myocardial infarction appears to be safe and does not increase microvascular damage. This route should be considered when testing novel cardioprotective agents.

    The aim of this study was to evaluate the prognostic values of ventricular wall motion score (WMS) and Global Registry of Acute Coronary Events (GRACE) score in patients with acute myocardial infarction (AMI) in a 12-month single-center prospective cohort. Consecutive inpatients diagnosed with AMI in the Department of Cardiology of The Second Affiliated Hospital of Soochow University from September 2012 through March 2015 were enrolled in this study. Echocardiography was issued to all subjects to calculate WMS within 24 hours after admission, and GRACE score of each patient was obtained simultaneously. During a 12-month follow-up period, all major adverse cardiac events (MACE) were recorded. After 12 months of observation, 124 of 635 patients with AMI developed MACE. The WMS (23.70 ± 3.80 versus 20.47 ± 3.25) and GRACE score (185.59 ± 45.16 versus 152.19 ± 36.51) were significantly higher in patients with MACE than those without MACE (P WMS (95% CI: 1.082-1.184, P WMS, GRACE score and the combination of WMS and GRACE score were 0.768 (P WMS and GRACE score were independent predictors of MACE in patients with AMI in 12-month follow-up, and the combined application of WMS and GRACE score can significantly improve the predictive value.

The most frequent planned management was conservative therapy in 423 (46%) patients, followed by TAVI in 261 (28%) and AVR in 244 (26%). The main reason against recommending AVR in 684 patients was high surgical risk [322 (47.1%)], other medical motives [193 (28.2%)], patient refusal [134 (19.6%)] and family refusal in the case of incompetent patients [35 (5.1%)]. The mean time from treatment decision to AVR was 4.8 ± 4.6 months and to TAVI 2.1 ± 3.2 months, P treatment: TAVI Hazard ratio (HR) 0.68 (95% confidence interval [CI] 0.49-0.93; P = 0.016) and AVR HR 0.56 (95% CI 0.39-0.8; P = 0.002). Octogenarians with symptomatic severe AS are frequently managed conservatively. Planned conservative management is associated with a poor prognosis. © 2013 The Association for the Publication of the Journal of Internal Medicine.

    Controlling cardiovascular risk factors (CVRF) is important for the outcome of interventional practices (percutaneous coronary intervention [PCI]) in ischemic heart disease. The aim is to determine the evolution of the CVRF 6 months after the intervention and their relationship with new events. A descriptive study was conducted on a case series. The variables recorded were: age, sex and chronic kidney disease (CKD), as well as total (TC) and HDL cholesterol, systolic (SBP) and diastolic blood pressure (DBP), smoking habit, and body mass index (BMI), before PCI and after 6 months. The occurrence of death or new PCI during the follow-up was considered an independent variable in a logistic regression analysis. A Pcontrol of CVRF was found. One fifth of the patients had an event in that period, showing association with age and CKD. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    Insufficient platelet inhibition is a major determinant of stent thrombosis (STh), although the etiology is multifactorial. On-clopidogrel platelet reactivity was investigated in patients with previous angiographically confirmed STh, myocardial infarction (MI), and controls. Using the Swedish Coronary Angiography and Angioplasty Registry, we identified patients with angiographically confirmed STh (n = 48) or MI (n = 30) while on dual antiplatelet therapy within 6 months of percutaneous coronary intervention (PCI) and matched control patients (n = 78). On-clopidogrel platelet reactivity was measured with VerifyNow P2Y12 and vasodilator-stimulated phosphoprotein (VASP) phosphorylation assay. The mean P2Y12 reaction units (PRU) was higher (246.8 ± 75.9 vs 200.0 ± 82.7, P = .001) in STh patients compared with controls. The optimal cutoff for STh was 222 PRU or higher (area under the curve 0.69, P STh or MI. STh was associated with high on-clopidogrel platelet reactivity measured with VerifyNow (cutoff level of PRU ≥222) but spontaneous MI in stented patients on clopidogrel treatment was not. There was, however, a substantial overlap in on-clopidogrel platelet reactivity between patients with and without on-treatment STh questioning the clinical use of platelet function testing to identify patients at high risk for STh.

    Full Text Available Introduction: Diabetes mellitus is associated with an increased risk of adverse clinical outcomes after percutaneous coronary intervention (PCI. The prognosis of patients with diabetes mellitus and chronic total occlusion (CTO treated with PCI is poorly investigated. Current study evaluates outcome of successful PCI on CTO in patients with and without diabetes. Methods: One hundred and sixty three patients treated with successful PCI on CTO between January 2009 and March 2011 were prospectively identified from the PCI registry at the Madani Heart Center, Tabriz, Iran. Patients were followed for 15±3 months, were evaluated for the occurrence of major adverse cardiac events (MACE comprising death, acute myocardial infarction, and need for repeat revascularization.Results: No differences were found in baseline clinical and procedural variables between patients with (n=34 and without diabetes (n=129, unless for hypertension (p=0.03. Hospitalization period after PCI in diabetics (3.26±0.61 days and non-diabetics (2.86±0.52 days was similar. In-hospital MACE occurred in 8 (23.5% individuals of diabetics and 10 (7.8% individuals of non-diabetics (p=0.02, among them revascularization was significantly higher in diabetics (20.6% vs. 7%, p=0.04. Follow-up events in diabetic and non-diabetic groups were 12 (35.3% and 37 (28.5%, respectively (p was not significant. Conclusion: In patients undergoing successful PCI on CTO, diabetes is associated with higher in-hospital adverse events; however diabetes does not affect long term outcomes in these patients.

    Full Text Available Background: Diabetes mellitus and admission blood glucose are important risk factors for mortality in ST segment elevation myocardial infarction patients, but their relative and individual role remains on debate. Objective: To analyze the influence of diabetes mellitus and admission blood glucose on the mortality of ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention. Methods: Prospective cohort study including every ST segment elevation myocardial infarction patient submitted to primary coronary percutaneous intervention in a tertiary cardiology center from December 2010 to May 2012. We collected clinical, angiographic and laboratory data during hospital stay, and performed a clinical follow-up 30 days after the ST segment elevation myocardial infarction. We adjusted the multivariate analysis of the studied risk factors using the variables from the GRACE score. Results: Among the 740 patients included, reported diabetes mellitus prevalence was 18%. On the univariate analysis, both diabetes mellitus and admission blood glucose were predictors of death in 30 days. However, after adjusting for potential confounders in the multivariate analysis, the diabetes mellitus relative risk was no longer significant (relative risk: 2.41, 95% confidence interval: 0.76 - 7.59; p-value: 0.13, whereas admission blood glucose remained and independent predictor of death in 30 days (relative risk: 1.05, 95% confidence interval: 1.02 - 1.09; p-value ≤ 0.01. Conclusion: In ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention, the admission blood glucose was a more accurate and robust independent predictor of death than the previous diagnosis of diabetes. This reinforces the important role of inflammation on the outcomes of this group of patients.

    Real time myocardial contrast echocardiography (RTMCE) is a cost-effective and simple method to quantify coronary flow reserve (CFR). We aimed to determine the value of RTMCE to predict cardiac events after percutaneous coronary intervention (PCI). We have studied myocardial blood volume (A), velocity (β), flow indexes (MBF, A × β), and vasodilator reserve (stress-to-rest ratios) in 36 patients with acute coronary syndrome (ACS) who underwent PCI. CFR (MBF at stress/MBF at rest) was calculated for each patient. Perfusion scores were used for visual interpretation by MCE and correlation with TIMI flow grade. In qualitative RTMCE assessment, post-PCI visual perfusion scores were higher than pre-PCI (Z = -7.26, P < 0.01). Among 271 arteries with TIMI flow grade 3 post-PCI, 72 (36%) did not reach visual perfusion score 1. The β- and A × β-reserve of the abnormal segments supplied by obstructed arteries increased after PCI comparing to pre-PCI values (P < 0.01). Patients with adverse cardiac events had significantly lower β- and lower A × β-reserve than patients without adverse cardiac events. In the former group, the CFR was ≥ 1.5 both pre- and post-PCI. CFR estimation by RTMCE can quantify myocardial perfusion in patients with ACS who underwent PCI. The parameters β-reserve and CFR combined might predict cardiac events on the follow-up. © 2015, Wiley Periodicals, Inc.

    Presented herein is a clinical case report regarding the use of hybrid technology in surgical treatment of a patient with an aneurysm of the distal portion of the aortic arch and coronary artery disease. The patient underwent a hybrid operation, i.e. debranching of the aortic arch branches, exoprosthetic repair of the ascending aorta, autovenous prosthetic coronary bypass grafting of the branch of the blunt edge of the anterior interventricular artery, stenting of the ascending portion, arch and descending portion of the aorta (stent graft "Medtronic Valiant"). In doing so, we used a non-standard approach to connecting the artificial circulation unit and to choosing the place for establishing proximal anastomoses of autovenous coronary bypass grafts. The early postoperative period was complicated by the development of respiratory insufficiency requiring continuation artificial pulmonary ventilation. The duration of the hospital stay of the patient amounted to 15 days. The check-up multispiral computed tomography showed normal functioning of the reconstruction zones, the stent graft is expanded, with no leak observed. The conclusion was made that hybrid interventions may be considered as an alternative to the classical surgical treatment associated in patients of older age group with a severe course of the postoperative period and high lethality.

    Renal insufficiency is associated with worse clinical outcomes in patients with coronary artery disease. Since the introduction of percutaneous coronary intervention (PCI), the revascularization therapy has evolved with advances of devices, improvements in operator techniques, and the establishment of medical therapy. We examined temporal trends of the clinical outcomes following PCI in patients with renal insufficiency. Patients with renal insufficiency after PCI at Juntendo University across three eras (plain balloon angioplasty, bare metal stent (BMS), and drug-eluting stent (DES)) were examined in this study. The primary endpoint was a composite of all-cause mortality, nonfatal acute coronary syndrome, nonfatal stroke, and repeat revascularization within 3-years after the index revascularization. A total of 1,420 patients were examined. Baseline characteristics have become unfavorable over time, whereas administration rate of medications for secondary prevention has increased. The event-free survival rates for the endpoint were different among the groups. Adjusted relative risk reduction for the endpoint was 35% and 51% in the BMS and DES eras (using the plain angioplasty era as reference). The adjusted relative risk reduction of the DES era was 26% compared with that of the BMS era. The incidence of cardiovascular events after PCI has reduced during the 26-year period mainly because of the reduction in repeat revascularization in patients with renal insufficiency, despite the higher risk profiles in the recent era.

  19. Antithrombotic management in patients with percutaneous coronary intervention requiring oral anticoagulation

    Full Text Available The dynamic evolution of therapeutic options including the use of vitamin K antagonists (VKA, non-vitamin K oral anticoagulants (NOAC, more potent antiplatelet drugs as well as new generation drug-eluting stents could lead to the view that the current recommendations on the management of patients with percutaneous coronary intervention (PCI requiring oral anticoagulation do not keep up with the results of several clinical studies published within the last 5 years. In the present overview, we summarize the recent advances in antithrombotic management used in atrial fibrillation patients undergoing PCI for stable coronary artery disease or acute coronary syndrome (ACS. The safety and efficacy of prasugrel and ticagrelor taken with oral anticoagulants also remain to be established in randomized trials; therefore the P2Y12 inhibitor clopidogrel on top of aspirin or without is now recommended to be used together with a VKA or NOAC. It is still unclear which dose of a NOAC in combination with antiplatelet agents and different stents should be used in this clinical setting and whether indeed NOAC are safer compared with VKA in such cardiovascular patients. Moreover, we discuss the use of anticoagulation in addition to antiplatelet therapy for secondary prevention in patients with ACS. To minimize bleeding risk in anticoagulated patients following PCI or ACS, the right agent should be prescribed to the right patient at the right dose and supported by regular clinical evaluation and laboratory testing, especially assessment of renal function when a NOAC is used.

    Timely reperfusion therapy is recommended for patients with ST-segment elevation myocardial infarction (STEMI), and door-to-balloon delay has been proposed as a performance measure in triaging patients for primary percutaneous coronary intervention (PCI). However, focusing on the time from first...... contact with the health care system to the initiation of reperfusion therapy (system delay) may be more relevant, because it constitutes the total time to reperfusion modifiable by the health care system. No previous studies have focused on the association between system delay and outcome in patients...

    A sensation of self-awareness on the relativity of our certainties comes over looking to the huge amount of data on antithrombotic therapies assessed in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). This sensation can be compared to the so-called "overview effect", a cognitive shift in awareness reported by some astronauts during spaceflight, often while viewing the Earth from orbit. In this review we will mention drugs floated like meteors in the Universe of STEMI treatment and we will discuss the body of evidence on oral and intravenous antithrombotic therapies for patients undergoing pPCI.

    Low body mass index (BMI) and serum creatinine are surrogate markers of frailty and sarcopenia. Their relationship with cause-specific mortality in elderly patients undergoing percutaneous coronary intervention is not well studied. We determined long-term cardiovascular and noncardiovascular mortality in 9394 consecutive patients aged ≥65 years who underwent percutaneous coronary intervention from 2000 to 2011. BMI and serum creatinine were divided into 4 categories. During a median follow-up of 4.2 years (interquartile range 1.8-7.3 years), 3243 patients (33.4%) died. In the multivariable model, compared with patients with normal BMI, patients with low BMI had significantly increased all-cause mortality (hazard ratio [HR] 1.4, 95% CI 1.1-1.7), which was related to both cardiovascular causes (HR 1.4, 95% CI 1.0-1.8) and noncardiovascular causes (HR 1.4, 95% CI 1.06-1.9). Compared with normal BMI, significant reduction was noted in patients who were overweight and obese in terms of cardiovascular mortality (overweight: HR 0.77, 95% CI 0.67-0.88; obese: HR 0.80, 95% CI 0.70-0.93) and noncardiovascular mortality (overweight: HR 0.85, 95% CI 0.74-0.97; obese: HR 0.82, 95% CI 0.72-0.95). In a multivariable model, in patients with normal BMI, low creatinine (≤0.70 mg/dL) was significantly associated with increased all-cause mortality (HR 1.8, 95% CI 1.3-2.5) and cardiovascular mortality (HR 2.3, 95% CI 1.4-3.8) compared with patients with normal creatinine (0.71-1.0 mg/dL); however, this was not observed in other BMI categories. We identified a new subgroup of patients with low serum creatinine and normal BMI that was associated with increased all-cause mortality and cardiovascular mortality in elderly patients undergoing percutaneous coronary intervention. Low BMI was associated with increased cardiovascular and noncardiovascular mortality. Nutritional support, resistance training, and weight-gain strategies may have potential roles for these patients undergoing

    Pre-hospitalization medication such as aspirin and nitrates has been shown to affect the mode of presentation in acute coronary syndrome (ACS). However, it is not formally assessed whether other cardiovascular medications may be contributed to the differences in the mode of presentation, especially in relation to coronary risk factors. We conducted a registration study of patients (M/F 850/323) with either ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) or unstable angina (UA), and examined the differences in the mode of presentation, pre-hospitalization medication, and coronary risk factors. The ratio of the incidence of STEMI and NSTEMI/UA was significantly reduced in patients having pre-hospitalization medication with aspirin, nitrates or statins, but not with other medications such as beta-blockers in multivariate analysis. Pre-hospitalization medication with aspirin and nitrates was significantly associated with the same reduction of the ratio in patients with male gender, hypertension, diabetes mellitus and a history of coronary artery disease. However, in patients who smoked, were obese and hypercholesterolemic, pre-hospitalization medication with nitrates was significantly associated with the reduced ratio. The ratio was significantly low in patients with males and hypercholesterolemia treated with statins before admission. Depending on their coronary risk factors, pre-hospitalization medication with aspirin, nitrates or statins was associated with a different presentation and evolution of ACS.

    To investigate the association of renal insufficiency and clinical outcomes in patients with acute coronary syndrome(ACS). The study was a multi-centre register study including 3,589 ACS patients coming from 39 centers across China who had received percutaneous coronary intervention(PCI) prior to 1st February, 2007. Estimated glomerular filtration rate (eGFR) was calculated for all patients using the 4-variable MDRD equation with the serum creatinine obtained before angiography. The association between renal insufficiency and clinical outcomes and the presence of in-hospital death and bleeding was studied by Fisher's exact test. Multi-variable analysis on the risk factors of in-hospital bleeding was done by logistic regression test. The mean age of the study population was (61.74+/-11.37) years (ranging from 23 years to 92 years)and 76.5% (2,746/3,589) of the population was male. Only 90 patients (2.51%) were known to have chronic kidney disease at the time of admission and 144 patients(4.01%) had serum creatinine levels above 133 micromol/L. However, after the evaluation of renal status by the MDRD equation, 2,250 patients (63.1%)showed a reduction in eGFR of less than 90 mL/min, of whom, 472 (13.1%) even reached the level of moderate renal insufficiency (eGFRchronic total occlusion lesions(CTO) and eight (0.22%) needed shift to coronary artery bypass grafting (CABG) after angiography. Both the presence of CTO lesions and CABG were proved to be associated with decrease of renal function through Fisher's exact test (P= 0.005 8 and 0.041, respectively). The in-hospital mortality rate was 0.47%(17/3 589) which was associated with the degree of renal insufficiency (P=0.001 3). A total of 75 patients(2.09%) of in-hospital bleeding were recorded with 26 patients(0.72%) diagnosed as major bleeding events. 92% (69/75) of the bleeding events occurred after PCI. Bleeding was found to be associated with the degree of renal insufficiency in every type of antithrombotic

    To investigate factors that influence annual prognosis in patients with non-ST-segment elevation acute coronary syndrome ((NSTEACS) concurrent with type 2 diabetes mellitus (DM2). The registry of patients with NSTEACS (non-ST-segment elevation myocardial infarction (NSTEMI), unstable angina) included 415 patients, of them 335 had no carbohydrate metabolic disorders, 80 had DM2. The follow-up period, during which the prognosis was evaluated in the patients, was one year after hospital discharge following the index NSTEACS event. Lipidogram readings and the serum levels of endothelin-1 (ET-1), sP-selectin, sE-selectin, and sPECAM were determined on day 10 after admission to hospital. All the patients underwent coronary angiography (CA), Doppler ultrasound of peripheral arteries during their hospital stay. The patients with DM2 versus those without diabetes proved to be significantly older and to have a higher body mass index; among them there were more women, they were noted to have more frequently hypertension and less frequently smoked. The presence of DM2 was associated with significantly increased intima-media thickness and higher GRACE scores (p=0.013) as compared to those in the patients with normal carbohydrate metabolism. There were significant differences in high-density lipoprotein levels that were lower, as well as in triglyceride levels and atherogenic index, which were higher in patients with DM2 than in those without this condition. In addition, there were significant differences in ET-1, sP-selectin, sE-selectin, and sPECAM levels that were significantly higher in the DM2 group. Moreover, the levels of ET-1 and sPECAM were above normal in both the DM and non-DM2 groups. Assessment of poor outcomes at one year of the observation established that cardiovascular mortality rates were significantly higher and coronary angiography was performed much less frequently in the DM2 group.

    Full Text Available Abstract Background Patients with coronary heart disease often do not follow prescribed physical activity recommendations. The aim of this study was to assess the efficacy of a behavioural intervention to increase physical activity in patients with coronary heart disease not attending structured cardiac rehabilitation programmes. Methods Parallel randomised controlled trial comparing 6-month multi-component behavioural change intervention (n = 71 with usual care (n = 85 was conducted in two hospitals in Jordan, Middle East. Intervention included one face-to-face individualised consultation, 6 telephone support calls (for goal-setting, feedback and self-monitoring and 18 reminder text messages. Patients were randomly allocated to the two groups by opening opaque sealed sequence envelopes. The patients and the researcher who provided the intervention and assessed the outcomes were not blinded. Outcomes were assessed at baseline and 6 months. Primary outcome was physical activity level, secondary outcomes were blood pressure, body mass index, exercise self-efficacy for exercise and health-related quality of life. Results Intervention and control groups were comparable at baseline. Moderate physical activity significantly increased in the intervention group compared with control group (mean change (SD of frequency: 0.23 (0.87 days/week versus -.06 (0.40; duration: 15.53 (90.15 minutes/week versus −3.67 (22.60 minutes/week; intensity: 31.05 (105.98 Metabolic equivalents (METs versus 14.68 (90.40 METs.

    Full Text Available Abstract Background The aim of this study was to assess the reporting of harm in randomized controlled trials evaluating stents for percutaneous coronary intervention. Methods The study design was a methodological systematic review of randomized controlled trials. The data sources were MEDLINE and the Cochrane Central Register of Controlled Trials. All reports of randomized controlled trials assessing stent treatment for coronary disease published between January 1, 2003, and September 30, 2008 were selected. A standardized abstraction form was used to extract data. Results 132 articles were analyzed. Major cardiac adverse events (death, cardiac death, myocardial infarction or stroke were reported as primary or secondary outcomes in 107 reports (81%. However, 19% of the articles contained no data on cardiac events. The mode of data collection of adverse events was given in 29 reports (22% and a definition of expected adverse events was provided in 47 (36%. The length of follow-up was reported in 95 reports (72%. Assessment of adverse events by an adjudication committee was described in 46 reports (35%, and adverse events were described as being followed up for 6 months in 24% of reports (n = 32, between 7 to 12 months in 42% (n = 55 and for more than 1 year in 4% (n = 5. In 115 reports (87%, numerical data on the nature of the adverse events were reported per treatment arm. Procedural complications were described in 30 articles (23%. The causality of adverse events was reported in only 4 articles. Conclusion Several harm-related data were not adequately accounted for in articles of randomized controlled trials assessing stents for percutaneous coronary intervention.

    The aim of this prospective, multicenter study was to assess the safety, feasibility, acceptance, and cost of ambulatory transradial percutaneous coronary intervention (PCI) under the conditions of everyday practice. Major advances in PCI techniques have considerably reduced the incidence of post-procedure complications. However, overnight admission still constitutes the standard of care in most interventional cardiology centers. Eligibility for ambulatory management was assessed in 370 patients with stable angina referred to three high-volume angioplasty centers. On the basis of pre-specified clinical and PCI-linked criteria, 220 patients were selected for ambulatory PCI. The study population included a substantial proportion of patients with complex procedures: 115 (52.3%) patients with multivessel coronary artery disease, 50 (22.7%) patients with multilesion procedures, and 60 (21.5%) bifurcation lesions. After 4-6 hr observation period, 213 of the 220 patients (96.8%) were cleared for discharge. The remaining seven (3.2%) patients were kept overnight for unstable angina (n = 1), atypical chest discomfort (n = 2), puncture site hematoma (n = 1), or non-cardiovascular reasons (n = 3). Within 24 hr after discharge, no patients experienced readmission, stent occlusion, recurrent ischemia, or local complications. Furthermore, 99% of patients were satisfied with ambulatory management and 85% reported no anxiety. The average non-procedural cost was lower for ambulatory PCI than conventional PCI (1,230 ± 98 Euros vs. 2,304 ± 1814 Euros, P < 10(-6)). Ambulatory PCI in patients with stable coronary artery disease is safe, effective, and well accepted by the patients. It may both significantly reduce costs and optimize hospital resource utilization. Copyright © 2012 Wiley Periodicals, Inc.

    BACKGROUND: Early stent thrombosis (ST) within 30 days after primary percutaneous coronary intervention in ST-segment-elevation myocardial infarction is a serious event. We sought to determine the predictors of and risk of mortality after early ST according to procedural antithrombotic therapy...... percutaneous coronary intervention with stent implantation at 188 international sites, randomized to either bivalirudin or heparin±a glycoprotein IIb/IIIa inhibitor (GPI). Early ST occurred in 100 patients (2.0%), 20 of whom (20.0%) died. Bivalirudin was associated with higher rates of early ST compared...... with bivalirudin compared with heparin±GPI because of increased ST within 4 hours after primary percutaneous coronary intervention. However, the mortality attributable to early ST was significantly lower after bivalirudin than after heparin±GPI. CLINICAL TRIAL REGISTRATION: URL: http...

    Positive psychological constructs, such as optimism, are associated with greater participation in cardiac health behaviors and improved cardiac outcomes. Positive psychology interventions, which target psychological well-being, may represent a promising approach to improving health behaviors in high-risk cardiac patients. However, no study has assessed whether a positive psychology intervention can promote physical activity following an acute coronary syndrome. In this article we will describe the methods of a novel factorial design study to aid the development of a positive psychology-based intervention for acute coronary syndrome patients and aim to provide preliminary feasibility data on study implementation. The Positive Emotions after Acute Coronary Events III study is an optimization study (planned N = 128), subsumed within a larger multiphase optimization strategy iterative treatment development project. The goal of Positive Emotions after Acute Coronary Events III is to identify the ideal components of a positive psychology-based intervention to improve post-acute coronary syndrome physical activity. Using a 2 × 2 × 2 factorial design, Positive Emotions after Acute Coronary Events III aims to: (1) evaluate the relative merits of using positive psychology exercises alone or combined with motivational interviewing, (2) assess whether weekly or daily positive psychology exercise completion is optimal, and (3) determine the utility of booster sessions. The study's primary outcome measure is moderate-to-vigorous physical activity at 16 weeks, measured via accelerometer. Secondary outcome measures include psychological, functional, and adherence-related behavioral outcomes, along with metrics of feasibility and acceptability. For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises

    Adherence to drugs and healthy lifestyles is low after acute coronary syndrome. We assessed whether trained community health workers could improve adherence to drugs, lifestyle changes, and clinical risk markers in patients with acute coronary syndrome in India. In this study done at 14 hospitals in India we randomly assigned (1:1) patients with acute coronary syndrome 1 or 2 days before discharge from hospital to a community health worker-based intervention group or a standard care group. Patients were randomly assigned with a telephone randomisation service. In the intervention group, during four in-hospital and two home visits, community health workers used unstructured discussions, visual methods, and patient diaries to educate patients on healthy lifestyle and drugs, and measures to enhance adherence. The primary outcome was adherence to proven secondary prevention drugs (antiplatelet drugs, β blockers, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and statins) estimated using a Composite Medication Adherence Scale at 1 year. The secondary outcomes were difference in lifestyle factors (diet, exercise, and tobacco and alcohol use), and clinical risk markers (blood pressure, bodyweight, BMI, heart rate, and lipids). All analyses were by intention to treat. This trial is registered with the Clinical Trial Registry of India, number REF/2013/03/004737, and ClinicalTrials.gov, number NCT01207700. Between Aug 23, 2011, and June 25, 2012, 806 participants were randomly assigned (405 to a community health worker-based intervention group and 401 to a standard care group). At 1 year, 40 patients had died and 15 had discontinued or been lost to follow-up, so 750 (93%) were included in the analyses (375 in each group). Secondary prevention drugs prescribed at discharge were 98% (786/803) for any antiplatelet drug, 79% (638/803) for dual antiplatelet drugs, 69% (555/803) for β blockers, 69% (552/803) for angiotensin-converting enzyme

    Objective: This study was performed to assess the knowledge of CAD risk factors and post management of coronary intervention among sample of population who were hospitalized for PCI. Methodology: A cross-sectional, descriptive survey was conducted in Cardiology ward of a tertiary care hospital from July 2013 to May 2015 on 600 patients. A structured questionnaire was used to interview the patients. In univariate analysis, t-tests were employed to assess association of knowledge of CAD risk factors with gender, education level and monthly household income. Results: The mean score of participants with no education was 4.42 and patients with education of bachelors or higher was 8.59 (p-value: 0.01). Similarly, the mean score for participants with monthly household income less than 5000 was 3.32 and participants with income higher than 50,000 had a score of 8.31 (p-value: 0.01). Furthermore, only 28% (N=168) claimed aerobic exercise as a key part of angioplasty recovery. Conclusions: Our results indicate the lack of good level of knowledge of risk factors for CAD and post management of coronary intervention among PCI patients of Pakistan. There is urgent need for targeted educational programs on national basis to reduce mortality associated with CAD in Pakistani population. PMID:26755481

    There are little published data reporting the effect of coronary artery chronic total occlusion (CTO) percutaneous coronary intervention (PCI) on the prognosis of elderly patients with identified CTOs. We sought to evaluate the clinical effect of CTO PCI on the prognosis of elderly patients with CTOs. A total of 445 consecutive patients diagnosed with a CTO by angiography from January 2011 to December 2013 were enrolled. We compared long-term clinical outcomes between the elderly group (≥75 years; n = 120, 27.0%), and the nonelderly group (elderly CTO patients had left main (LM) disease (25.0 versus 15.1%, P = 0.015), 3-vessel disease (96.4% versus 73.8%, P elderly patients had a higher syntax score than nonelderly patients (27.0 [25.0, 30.0] versus 26.0 [23.0, 30.0], P = 0.006). PCI was attempted for 33 out of 135 CTO lesions (24.4%) in the elderly group, and 127 out of 378 lesions (33.6%) in the nonelderly group (P = 0.049); however, there were no statistically significant differences in the CTO PCI success rates between the 2 groups (69.7% versus 82.7%, P = 0.097). The 3-year cardiac mortality rate was 15.0% and 4.6% (P elderly and nonelderly groups, respectively. Elderly patients with CTOs who were recanalized by PCI and those with unopened CTOs exhibited comparable 3-year cardiac mortality rates (15.0% versus 16.0%, P = 1.000). There was no significant difference in primary endpoint incidence (25.0% versus 33.0%, P = 0.486). Multivariate analysis revealed that after corrections for baseline and procedural differences, right coronary artery CTO (odds ratio = 4.600, 95% CI: 1.320-16.031; P = 0.017) and LM disease combined with 3-vessel disease (odds ratio = 4.296, 95% CI: 1.166-15.831; P = 0.028) were independent predictors of 3-year cardiac mortality among elderly patients with CTOs. Elderly patients with CTOs presented with seriously diseased coronary arteries and poor prognoses. CTO PCI did not seem to significantly improve long-term clinical outcomes among

Previous studies have been vulnerable to possible selection bias. In the study reported here, we examined the association between self-rated health and adverse events in terms of cardiac events, cardiac readmissions, and all-cause mortality in a complete cohort of patients treated with percutaneous coronary intervention (PCI.Study design and setting: A cohort of patients with coronary heart disease treated with PCI was followed up with questionnaires 4 weeks after PCI to measure self-rated health and in registers to identify adverse events. Of 1,752 eligible patients under 67 years, 26 died during the first 4 weeks. A total of 224 patients were excluded from the analysis because they were readmitted with a cardiac diagnosis before answering the first questionnaire. We received complete SF-12 Health Survey component summaries from 984 of the remaining 1,502 patients. We used multiple imputation to establish a complete cohort, including nonrespondents.Results: During follow-up, 83 patients died, 220 patients experienced a new cardiac event, and 526 patients experienced a hospital readmission related to coronary heart disease. Poor self-rated health was related to cardiac events, cardiac readmission, and all-cause mortality. The associations were stronger for all-cause mortality than for events and readmissions. Physical health was more important than mental health, but both revealed an exposure–response pattern

    In this study, we aimed to investigate the impact of prophylactic intracoronary adenosine administered during percutaneous coronary intervention (PCI) due to unstable angina pectoris on myonecrosis by measuring post-procedural levels of cardiac troponin I (cTnI) and creatine kinase-myocardial band (CK-MB). A total of 122 patients with unstable angina undergoing PCI were included in this single-center, double-blind, randomized study. The patients were randomly allocated to adenosine and placebo groups. In the adenosine group, a single-dose of intracoronary adenosine (100 μg for the right coronary artery and 150 μg for the left coronary artery) was administered. Primary endpoint was post-PCI myonecrosis, which was defined as abnormal levels of periprocedural cTnI. Secondary endpoints were defined as elevated cTnI levels [5 × upper limit of normal (ULN)], abnormal CK-MB levels, angiographic coronary flow measured by Thrombolysis In Myocardial Infarction (TIMI) frame count (TFC), the cumulative incidence of in-hospital death and in-hospital urgent target vessel revascularization (TVR). Clinical and angiographic characteristics of both adenosine (61 patients, 61 ± 9 years) and placebo (61 patients, 59 ± 10 years) groups were similar (p > 0.05 for all). Post-procedural abnormal cTnI levels in the adenosine group were significantly lower than the placebo group (32 % vs. 55 %, p: 0.011). cTnI >5 × ULN (21 % vs. 31 %, p: 0.217) and abnormal CK-MB levels (11 % vs. 19 %, p: 0.263) were similar in both groups. Post-procedural TFCs in the adenosine group were significantly lower than the placebo group (24 ± 4 vs. 27 ± 5, p: 0.004). In-hospital events including death and urgent TVR were not observed in either group. Intracoronary administration of single-dose adenosine in patients with unstable angina undergoing PCI is associated with decreased periprocedural myonecrosis and improved coronary blood flow.

    Background Utilization of cardiac rehabilitation is suboptimal. The aim of the study was to assess referral trends over the past decade, to identify predictors for referral to a cardiac rehabilitation program, and to evaluate the association with one-year mortality in a large national registry of acute coronary syndrome patients. Design and methods Data were extracted from the Acute Coronary Syndrome Israeli Survey national surveys between 2006-2013. A total of 6551 patients discharged with a diagnosis of acute coronary syndrome were included. Results Referral to cardiac rehabilitation following an acute coronary syndrome increased from 38% in 2006 to 57% in 2013 ( p for trend following independent predictors for non-referral: 2006 survey, older age, female sex, past stroke, heart or renal failure, prior myocardial infarction, minority group, and lack of in-hospital cardiac rehabilitation center (all p follow-up ( p = 0.03). Consistently, a 32% lower one-year mortality risk was evident in a propensity score matched group of 3340 patients (95% confidence interval 0.48-0.95, p = 0.02). Conclusions Over the past decade there was a significant increase in cardiac rehabilitation referral following an acute coronary syndrome. However, cardiac rehabilitation is still under-utilized in important high-risk subsets of this population. Patients referred to cardiac rehabilitation have a lower adjusted mortality risk.

    Congenital aomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most common anomaly of the aortic arch, occurring in 0.5-2.5% of individuals. We report the case of a 48-year-old man suffering from acute inferoposterior-wall ST elevation myocardial infarction successfully treated by primary percutaneous coronary intervention.Ten years ago, the patient had undergone coronary artery bypass graft surgery with the implantation of two arterial grafts- left and right internal mammary arteries on both left anterior descending and right coronary artery. After several attempts to canulate truncus brachiocephalicus, angiogram revealed the left aortic arch with the aberrant right subclavian artery. To our knowledge, this is the first described case of primary percutaneous coronary intervention via the aberrant right subclavian artery and right internal mammary artery graft with stent implantation in the infarct related lesion of the distal segment of right coronary artery. Subsequent 64-multidetector computed tomography confirmed the angiographic findings. Early recognition of congenital anomalies of the aortic arch and its great vessels, even before coronary artery bypass graft surgery, could be crucial for the urgent and successful treatment of patients with life-threatening conditions, such as ST segment elevation myocardial infarction.

    Culprit plaque characteristics in young patients who experience an Acute Coronary Syndrome (ACS) evaluated by OCT (Optical Coherence Tomography) have to be defined. The OCT-FORMIDABLE is a multicentre retrospective registry enrolling consecutive patients with ACS who performed OCT in 9 European centres. Patients were divided in two groups according to age at presentation: juvenile-ACS (age ≤ 50 years) and not juvenile-ACS (age > 50 years). Primary end-point was the prevalence of plaque rupture (PR). Secondary end point was the prevalence of thin cap fibro atheroma (TCFA), fibrocalcific and fibrotic plaque. 285 patients were included, 71 (24.9%) in juvenile-ACS group and 215 (75.1%) in not juvenile-ACS group. Younger patients showed a trend for a higher prevalence of TCFA (70 vs. 58%, P = 0.06) and thrombus presence (62 vs. 51%, P = 0.1), while no statistical difference concerning PR (70 vs. 64%, P = 0.29). Of interest patients younger that 35 years showed a higher prevalence of PR compared to patients aged between 35 and 45 or 45 and 50 years (100 vs. 72 vs. 55%, P = 0.03). Culprit plaque in juvenile-ACS group showed more frequently a reduced mean cap thickness (119 ± 66 vs. 155 ± 95 nm, P = 0.05) and less frequently fibrotic (32 vs. 57%, P < 0.001) or fibrocalcific (17 vs. 36%, P = 0.003) characteristics. young patients with ACS show a trend for a higher prevalence of culprit PR, a thinner cap and less fibrotic or fibrocalcific components. © 2017 Wiley Periodicals, Inc.

    The following registry (Katowice-Zabrze retrospective registry) aimed to assess the influence of a chronic kidney disease (CKD) on long-term clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) using either first-generation (DES-I) or second-generation (DES-II) drug-eluting stents. The study group consisted of 1,908 consecutive patients, of whom 331 (17.3%) had CKD. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/m 2 . We evaluated the major adverse cardiac and cerebral events (MACCE), i.e., the composite of death, myocardial infarction (MI), stroke, and target vessel revascularization at the 12-month follow-up. CKD patients had a lower left ventricular ejection fraction and more often a history of MI and PCI. Coronary angiography revealed that multivessel coronary artery disease, intracoronary thrombus, and extensive calcifications were more frequent in patients with CKD. However, the SYNTAX score did not vary between patients with or without CKD. There was a higher rate of in-hospital bleedings requiring blood transfusion in patients with CKD. At the 1-year follow-up, MACCE (17.8 vs. 12.6%, HR = 1.46 [95% CI 1.05-2.03], p = 0.009) and death (8.4 vs. 2.3%, HR = 3.9 [95% CI 2.0-7.5], p < 0.001) were more often observed in CKD patients. Multivariable Cox analysis revealed that CKD was an independent risk predictor of death after PCI at the 1-year follow-up (HR = 2.1 [95% CI 1.2-3.6], p = 0.004). In comparison to DES-I, the use of DES-II did not decrease the adverse effect of CKD on MACCE. CKD patients had an increased risk of in-hospital bleeding requiring blood transfusion and a higher risk of MACCE and death at the 12-month follow-up. The use of second-generation DES did not improve clinical outcomes in patients with CKD at the 12-month follow-up.

    The aim of this study was to investigate the incidence of permanent working disability (PWD) in young patients after percutaneous or surgical coronary revascularization. The study included 1035 consecutive patients ≤50 years old who underwent coronary revascularization [910 and 125 patients in percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) groups, respectively] between 2002 and 2012 at 4 Finnish hospitals. The median follow-up time was 41 months. The overall incidence of PWD was higher after CABG compared to PCI (at 5 years, 34.8 vs. 14.7%, P disability pension was 11.6 months after CABG and 24.4 months after PCI (P = 0.018). Reasons for PWD were classified as cardiac (35.3 vs. 36.9%), psychiatric (14.7 vs. 14.6%), and musculoskeletal (14.7 vs. 15.5%) in patients undergoing CABG vs. PCI. Overall freedom from PWD was higher in patients without major adverse cardiac and cerebrovascular event (MACCE) (at 5 years, 85.6 vs. 71.9%, P < 0.001). Nevertheless, rate of PWD was high also in patients without MACCE and patients with preserved ejection fraction during follow-up. Although coronary revascularization confers good overall survival in young patients, PWD is common especially after CABG and mostly for cardiac reasons even without occurrence of MACCE. Supportive measures to preserve occupational health are warranted concomitantly with coronary revascularization at all levels of health care.

    Aortic valve calcification (AVC) is a common progressive condition that involves several inflammatory and atherosclerotic mediators. However, it is unclear whether the occurrence of periprocedural myocardial injury (PMI) after elective coronary intervention is associated with AVC in stable coronary artery disease (CAD) patients. A total of 530 stable CAD patients who underwent elective coronary intervention were enrolled in this clinical study. High sensitive cardiac troponin T (hs-cTnT) was detected before and after the procedure. PMI was defined as hs-cTnT after coronary intervention higher than 99th percentile upper reference limit (URL). All patients underwent echocardiography to detect the occurrence of AVC. Univariate and multivariate analyses were applied to analyze risk factors of PMI. A total of 210 patients (39.6 %) were diagnosed with PMI after elective coronary intervention. Compared with non-AVC patients (n = 386), AVC patients (n = 144) had higher rate of PMI (64.6 vs. 30.3 %, P AVC had higher Gensini score (39.9 ± 26.6 vs. 34.2 ± 22.1, P AVC patients had increased risk of PMI compared with non-AVC patients. Importantly, even after being adjusted by multivariate analysis, AVC still independently increased the risk of PMI (OR = 3.329, 95 % CI = 2.087-5.308, P AVC significantly increased the risk of PMI after elective coronary intervention. It could be one of the independent predictors for PMI in stable CAD patients.

    During the past decade, the volume of percutaneous coronary intervention (PCI) in China has risen by more than 20-fold. Yet little is known about patterns of care and outcomes across hospitals, regions and time during this period of rising cardiovascular disease and dynamic change in the Chinese healthcare system. Using the China PEACE (Patient-centered Evaluative Assessment of Cardiac Events) research network, the Retrospective Study of Coronary Catheterisation and Percutaneous Coronary Intervention (China PEACE-Retrospective CathPCI Study) will examine a nationally representative sample of 11 900 patients who underwent coronary catheterisation or PCI at 55 Chinese hospitals during 2001, 2006 and 2011. We selected patients and study sites using a two-stage cluster sampling design with simple random sampling stratified within economical-geographical strata. A central coordinating centre will monitor data quality at the stages of case ascertainment, medical record abstraction and data management. We will examine patient characteristics, diagnostic testing patterns, procedural treatments and in-hospital outcomes, including death, complications of treatment and costs of hospitalisation. We will additionally characterise variation in treatments and outcomes by patient characteristics, hospital, region and study year. The China PEACE collaboration is designed to translate research into improved care for patients. The study protocol was approved by the central ethics committee at the China National Center for Cardiovascular Diseases (NCCD) and collaborating hospitals. Findings will be shared with participating hospitals, policymakers and the academic community to promote quality monitoring, quality improvement and the efficient allocation and use of coronary catheterisation and PCI in China. http://www.clinicaltrials.gov (NCT01624896).

    Coronary artery disease (CAD) is one of the leading causes of premature death in Germany. Percutaneous coronary interventions (PCI) are frequently performed in patients with angiographically intermediate stenoses. However, the necessity of PCI has not been proven for all patients. Pressure-based fractional flow reserve (FFR) is an invasive test that can be used to assess the functional significance of intermediate coronary stenoses in order to guide decisions on PCI. This health technology assessment (HTA) aims to evaluate (1) the diagnostic accuracy, (2) the risk-benefit trade-off and (3) the long-term cost-effectiveness of FFR measurement to guide the decision on PCI in patients with stable angina pectoris and intermediate coronary stenoses. We performed a literature search in medical and HTA databases. We used the DIMDI instruments (DIMDI = Deutsches Institut für Medizinische Dokumentation und Information/German Institute for Medical Information and Documentation) to assess study quality and to extract and summarize the information in evidence tables. We performed a meta-analysis to calculate the pooled overall estimate for sensitivity and specificity of FFR with 95% confidence intervals (95% CI). Individual studies' case numbers were used as weights. The influence of single studies and important covariates on the results was tested in sensitivity analyses. We developed the German Coronary Artery Disease Outcome Model (German CADOM), a decision-analytic Markov model, to estimate the long-term effectiveness and cost-effectiveness of FFR measurement in the context of the German healthcare system. Our literature search identified twelve studies relevant to this HTA-report including ten diagnostic accuracy studies of FFR measurement, one randomized clinical trial (RCT) investigating the clinical benefits of this technique as well as one economic evaluation. Pooled estimates for sensitivity and specificity were 81.7% (95% CI: 77.0-85.7%) and 78.7% (95% CI: 74

    Drug-eluting stents (DES) reduce risk of in-stent restenosis after percutaneous coronary intervention (PCI) but require dual antiplatelet therapy (DAPT) for a longer term than bare-metal stents (BMS). Few studies have examined clinical predictors of DES vs BMS, and variability in provider selection between DES and BMS in clinical practice has not been well described. These insights can inform our understanding of current practice and may identify opportunities to improve decision-making stent selection decinsion-making. In a multicenter registry, 3295 consecutive patients underwent PCI by 158 interventional cardiologists across 10 US sites. Eighty percent of patients with treated with DES. Using hierarchical regression, diabetes mellitus, multivessel disease, health insurance, and white race were independently associated with greater DES use, whereas increasing age, history of hypertension, anticipated surgery, use of warfarin, lower hemoglobin, prior history of bleeding, and treatment of right coronary and left circumflex artery lesions as compared with PCI of left anterior descending artery were associated with lower likelihood of receiving DES. Adjusted rates of DES use across providers varied from 52.3% to 94.6%, and adjusted median odds ratio for DES selection was 1.69. DES selection appeared to reflect physicians' attempts to balance benefits of DES against risks of prolonged DAPT. Nevertheless, marked residual variability in DES selection across providers persisted after adjusting for predictors of restenosis, bleeding, and other factors. Further studies are needed to better understand drivers of this variability and identify the impact of patient and provider preferences on stent selection at the time of PCI. © 2017 Wiley Periodicals, Inc.

    Acute coronary syndrome (ACS) is an important cause of mortality and significant personal and financial costs. Cardiac rehabilitation (CR) programs have shown positive effects in reducing cardiovascular mortality and improving functional capacity. However, adherence is low and appears to be influenced by psychosocial factors, such as patients' cognitions and emotional state. The objective was to evaluate the efficacy of a brief in-hospital psychological intervention to promote cognitive and emotional adaptation after ACS. One hundred and twenty-one patients with ACS, admitted to a coronary care unit in a central hospital, were randomized to an experimental group (EG, n=65) and a control group (CG, n=56). Portuguese versions of the HADS and BIPQ were used to measure emotional well-being and illness cognitions. Two 1 h 15 min sessions were conducted 2-3 days after hospital admission, and a 20-minute follow-up session took place one month after discharge. Patients were assessed at four different time points: pre-test, post-test, and at 1- and 2-month follow-up. The intervention had significant effects on anxiety, depression and illness cognitions. Anxiety and depression were significantly reduced and illness cognitions improved significantly in the EG compared to the control group. For the EG, these changes were maintained or enhanced at 1- and 2-month follow-up, whereas for the CG there was a deterioration in psychosocial adjustment. These results indicate that a brief psychological intervention program delivered during hospitalization for ACS and combined with standard medical care can have positive effects in terms of psychosocial outcomes that have proven impact on cardiac rehabilitation and prognosis.

    2017-01-01

    The Korea Acute Myocardial Infarction Registry (KAMIR) is the first nationwide registry that reflects current therapeutic approaches and acute myocardial infarction (AMI) management in Korea. The results of the KAMIR demonstrated different risk factors and responses to medical and interventional treatments. The results indicated that the incidence of ST-elevation myocardial infarction (STEMI) was relatively high, and that the prevalence of dyslipidemia was relatively low with higher triglyceride and lower high-density lipoprotein cholesterol levels. Percutaneous coronary intervention (PCI) rates were high for both STEMI and non-ST-elevation myocardial infarction (NSTEMI) with higher use of drug-eluting stents (DESs). DES were effective and safe without increased risk of stent thrombosis in Korean AMI patients. Triple antiplatelet therapy, consisting of aspirin, clopidogrel, and cilostazol, was effective in preventing adverse clinical outcomes after PCI. Statin therapy was effective in Korean AMI patients, including those with very low levels of low-density lipoprotein cholesterol and those with cardiogenic shock. The KAMIR score had a greater predictive value than Thrombolysis in Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) scores for long-term mortality in AMI patients. Based on these results, the KAMIR will be instrumental for establishing new therapeutic strategies and effective methods for secondary prevention of AMI and guidelines for Asian patients.

  10. Detecting Restenosis after Percutaneous Coronary Intervention Using Exercise-Stress Electrocardiogram Findings Including QT Dispersion

    Directory of Open Access Journals (Sweden)

    Bonpei Takase, MD

    2006-01-01

    Full Text Available Despite the advent of drug-eluting stents in Japan, bare metal stents or conventional balloon angioplasty are still indicated in some patients needing elective percutaneous coronary intervention (PCI and in patients with acute coronary syndrome if these patients develop side effects while taking ticlopidine. In such patients, restenosis is a problem that is difficult to diagnose. To investigate the comparative diagnostic accuracy of the exercise-stress electrocardiogram (ECG for detecting restenosis after PCI, we measured conventional ST-segment changes and QT dispersion during exercise-stress testing in 173 patients with elective PCI (63 ± 10 years old. Exercise-stress testing was performed 3 to 6 months after successful PCI, and restenosis was confirmed by follow-up coronary angiogram. There were 98 patients with a prior myocardial infarction (prior MI group and 76 patients with no prior myocardial infarction (no MI group. Restenosis was found in 45 patients (46% in the prior MI group and 26 patients (34% in the no MI group. Conventional ST-segment depression (>1:0 mm, J 60 ms indicating exercise-induced myocardial ischemia had a sensitivity of around 50% and a specificity of around 70% for diagnosing restenosis in both groups. In the prior MI group, QT dispersion was increased by exercise-stress testing in both patients with and without restenosis, whereas in the no MI group, QT dispersion increased only in patients with restenosis. With a cut-off value of >60 ms, QT dispersion had a sensitivity of 54% and a specificity of 68% for detecting restenosis in the no MI group; these values were comparable to those seen with conventional ST-segment changes. In conclusion, due to its low cost, exercise-stress ECG remains useful for diagnosing restenosis following PCI if the clinician understands its limited sensitivity and specificity. The presence of a prior MI must be considered when QT dispersion during exercise-stress testing is used for

    Objective: To determine the incidence of contrast nephropathy in high-risk patients undergoing coronary angiography and percutaneous coronary intervention (PCI), and to define the characteristics of this cohort. Design: Descriptive study. Place and Duration of Study: The Aga Khan University Hospital, Karachi from January to December 2002. Patients and Methods: One hundred and fifteen patients with serum creatinine greater than 1.4mg/dl who underwent coronary angiography or PCI were included. All patients received non-ionic contrast dye. Acute contrast nephropathy was defined as rise in serum creatinine of >0.5mg/dl within 48 hours following the index procedure. Means and standard deviations were calculated for continuous variables and frequencies for categorical variables. Results: Mean age of patients was 62.3 year + 8.83. Mean pre-contrast creatinine was 1.9+0.9mg/dl. Eleven (9.65%) patients developed contrast nephropathy. 4.4% of patients with serum creatinine 4.0(p-value 0.001). 11.9% diabetic patients developed nephropathy compared to 6.3% of non-diabetics (p-value 0.355). 11.4% of hypertensive and 3.7% of non-hypertensive patients developed contrast-nephropathy (p-value 0.454). 12.9% of low dose group ( 100ml) developed nephropathy (p-value 0.188). Mean serum creatinine in low dose group was higher (3.0mg/dl vs. 1.7 mg/dl). Conclusion: The incidence of contrast nephropathy in this study was similar to that reported in literature. Risk of CIN was found to be significantly proportional to the severity of baseline renal disease. Trends towards higher risk of CIN were seen in patients with diabetes and hypertension. Higher incidence of CIN in patients receiving low-dose contrast was confounded by higher baseline serum creatinine in that group. (author)

    To study the causes of and to develop a risk score for failure of transradial approach (TRA) for percutaneous coronary intervention (PCI). TRA-PCI failure has been reported in 5% to 10% of cases. TRA-PCI failure was categorized as primary (clinical reasons) or crossover failure. Multivariate analysis was performed to determine independent predictors of TRA-PCI failure, and an integer risk score was developed. From January to June 2010, TRA-PCI was attempted in 1,609 (97.3%) consecutive patients, whereas 45 (2.7%) had primary TRA-PCI failure. Crossover TRA-PCI failure occurred in 30 (1.8%) patients. Causes of primary TRA-PCI failure included chronic radial artery occlusion (11%), previous coronary artery bypass graft (27%), and cardiogenic shock (20%). Causes for crossover TRA-PCI failure included: inadequate puncture in 17 patients (57%); radial artery spasm in 5 (17%); radial loop in 4 (13%); subclavian tortuosity in 2 (7%); and inadequate guide catheter support in 2 (7%) patients. Female sex (odds ratio [OR]: 3.2; 95% confidence interval [CI]: 1.95 to 5.26, p < 0.0001), previous coronary artery bypass graft (OR: 6.1; 95% CI: 3.63 to 10.05, p < 0.0001), and cardiogenic shock (OR: 11.2; 95% CI: 2.78 to 41.2, p = 0.0011) were independent predictors of TRA-PCI failure. Risk score values from 0 to 7 predicted a TRA-PCI failure rate from 2% to 80%. In a high-volume radial center, 2.7% of patients undergoing PCI are excluded from initial TRA on clinical grounds, whereas crossover to femoral approach is required in only 1.8% of the cases. A new simple clinical risk score is developed to predict TRA-PCI failure. Copyright © 2013 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

Methods: Residents of central Massachusetts hospitalized with STEMI who received a primary PCI at two major PCI-capable medical centers in central Massachusetts on a biennial basis between 2001 and 2011 comprised the study population (n=629. Multivariable regression analyses were used to examine factors associated with failing to receive a primary PCI within 90 minutes after emergency department (ED arrival. Results: The average age of this patient population was 61.9 years; 30.5% were women, and 91.7% were White. During the years under study, 50.9% of patients received a primary PCI within 90 minutes of ED arrival; this proportion increased from 2001/2003 (17.2% to 2009/2011 (70.5% (P<0.001. Having previously undergone coronary artery bypass graft surgery, arriving at the ED by car/walk-in and during off-hours were significantly associated with a higher risk of failing to receive a primary PCI within 90 minutes of ED arrival. Conclusion: The likelihood of receiving a timely primary PCI in residents of central Massachusetts hospitalized with STEMI at the major teaching/community medical centers increased dramatically during the years under study. Several groups were identified for purposes of heightened surveillance and intervention efforts to reduce the likelihood of failing to receive a timely primary PCI among patients acutely

    The aim of this study is to investigate the association between fractional flow reserve (FFR) values and change in coronary physiological indices after elective percutaneous coronary intervention (PCI). Decision making for revascularization when FFR is 0.75-0.80 is controversial. A retrospective analysis was performed of 296 patients with stable angina pectoris who underwent physiological examinations before and after PCI. To investigate the differences of coronary flow improvement between territories with low-FFR (zone FFR (0.75-0.80), serial changes in physiological indices including mean transit time (Tmn), coronary flow reserve (CFR), and index of microcirculatory resistance (IMR) were compared between these two groups. Compared to low-FFR territories, grey-zone FFR territories showed significantly lower prevalence of Tmn shortening, CFR improvement, and decrease in IMR (Tmn shorting, 63.9% vs. 87.0%, P 51.3% vs. 63.3%, P = .040) and lower extent of their absolute changes (Tmn shorting, 0.06 (-0.03 to 0.16) vs. 0.22 (0.07-0.45), P zone FFR. Physiological assessment combining FFR and IMR may help identify patients who may benefit by PCI, particularly those in the grey zone. © 2018 Wiley Periodicals, Inc.

    The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. We queried the 2007-2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, Pacute coronary syndrome or stable ischemic heart disease. In patients undergoing PCI, chronic renal insufficiency is associated with higher in-hospital mortality, higher postprocedure hemorrhage, longer average length of stay, and higher average hospital charges. © 2015 The Authors.

    Objective: To evaluate the determinants of successful recanalization of chronic coronary arterial total occlusion (CTO) by percutaneous coronary intervention (PCI) as well as the effect of the recanalization on the prognosis of the patients. Methods: Fifty-two patients with CTO were treated by PCI. 30 patients (duration more than one month) were successfully recanalized with stent implantation. Their clinical features and prognosis were compared with those without successful recanalization. Results: Compared with patients without successful recanalization, patients with successful recanalization had a higher incidence of hypertension (53% vs 23%, P<0.05), shorter duration of the predicted occlusion (P<0.01), lower plasma concentration of total cholesterol [(4.8 ± 0.85) vs (5.6 ± 1.5) mmol/L, P<0.05], lower percentage of the lesions with clear out stump or with bridging collaterals or with a branch at orifice or of long segment (17% vs 45%, P<0.05); more frequently free of angina (73% vs 50%, P<0.05) and had lower combination end points including repeated PCI, CABG and hospilization (13% vs 36% P<0.05) during follow-up. Conclusions: Duration of occlusion, the length of occlusion, the occlusion with a missing stump or bridging collaterals are key factors for success or failure of recanalization of TCO by PCI. Patients with successful PCI of CTO have a better prognosis. (authors)

    Despite improvements in guidewire technologies, the traditional antegrade wire escalation approach to chronic total occlusion (CTO) recanalization is successful in only 60-80% of selected cases. In particular, long, calcified, and tortuous occlusions are less successfully approached with a true-to-true lumen approach. Frequently, the guidewire tracks into the subadventitial space, with no guarantee of distal re-entry into the true lumen. The ability to manage the subadventitial space has been a key step in the tremendous improvement in success rates of contemporary CTO percutaneous coronary intervention (PCI), whether operating antegradely or retrogradely. A modern approach to CTO PCI involves understanding the concept of "vessel architecture," which is based on the distinction between coronary structures (occlusive plaque, comprising the disrupted intima and media, and the outer adventitia) and extravascular space. The vessel architecture represents a safe work environment for guidewire and device manipulation. This review provides an anatomy-based description of the concept of vessel architecture, along with a historical perspective of subadventitial techniques for CTO PCI, and outcome data of CTO PCI utilizing the subadventitial space. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Apart from their role in hemostasis and thrombosis, platelets are involved in many other biological processes such as wound healing and angiogenesis. Percutaneous coronary intervention is a highly thrombogenic procedure inducing platelets and monocytes activation through endothelial trauma and contact activation by intravascular devices. Platelet P2Y{sub 12} receptor activation by adenosine diphosphate facilitates non-ADP agonist-mediated platelet aggregation, dense granule secretion, procoagulant activity, and the phosphorylation of several intraplatelet proteins, making it an ideal drug target. However, not all compounds that target the P2Y{sub 12} receptor have similar efficacy and safety profiles. Despite targeting the same receptor, the unique pharmacologic properties of each of these P2Y{sub 12} receptor-directed compounds can lead to very different clinical effects.

METHODS: In this prospective observational study, we included patients with suspected STEMI within the region covered by the HEMS from January 1, 2010, to April 30, 2013, transported by either...... HEMS or ground emergency medical services (GEMS) to the regional PCI centre. The primary outcome was 30-day mortality. RESULTS: Among the 384 HEMS and 1220 GEMS patients, time from diagnostic ECG to PCI centre arrival was lower with HEMS (median 71 min vs. 78 min with GEMS; P = 0.004). Thirty...

    Five percent of patients who went through Percutaneous Coronary Intervention (PCI) experienced Major Adverse Cardiac Events (MACE) after PCI procedure. Risk prediction of MACE following a PCI procedure therefore is helpful. This work describes a review of such prediction models currently in use. Literature search was done on PubMed and SCOPUS database. Thirty literatures were found but only 4 studies were chosen based on the data used, design, and outcome of the study. Particular emphasis was given and commented on the study design, population, sample size, modeling method, predictors, outcomes, discrimination and calibration of the model. All the models had acceptable discrimination ability (C-statistics >0.7) and good calibration (Hosmer-Lameshow P-value >0.05). Most common model used was multivariate logistic regression and most popular predictor was age.

  9. Incidental finding of arteria lusoria during transradial coronary catheterization: Significance in interventional cardiology.

    Arteria lusoria is the most common anomaly of the aortic arch with an incidence of 0.5%-2.5%. It is mostly diagnosed incidentally while performing imaging for evaluation of other unrelated medical conditions. The aberrant right subclavian artery arises beyond the origin of the left subclavian artery from the aortic arch. This results in a complex right-subclavian-aortic anatomy which leads to difficulty in transradial coronary angiography. This can lead to prolonged procedure time and increased use of catheters by unaware interventionists. This is even more important if this is encountered in the setting of an acute myocardial infarction. Our review takes into account clinical significance of this uncommon anomaly in the field of interventional cardiology. © 2017 Wiley Periodicals, Inc.

    The purpose of this research was to measure accurate patient entrance skin dose and maximum skin absorbed dose (MSD) to prevent radiation skin injuries in percutaneous coronary interventions (PCIs). We directly measured the MSD on 50 PCIs by using multiple radiophotoluminescence glass dosimeters and a modified dosimetry gown. Also, we analysed the correlation between the MSD and indirect measurement parameters, such as fluoroscopic time (FT), dose-area product (DAP) and cumulative air kerma (C-AK). There were very strong correlations between MSD and FT, DAP and C-AK, with the correlation between MSD and C-AK being the strongest (r = 0.938). In conclusion, the regression lines using MSD as an outcome value (y) and C-AK as predictor variables (x) were y = 1.12x (R 2 = 0.880). From the linear regression equation, MSD is estimated to be ∼1.12 times that of C-AK in real time. (authors)

    Identifying reperfusion and predicting post procedure risk is important following Percutaneous Coronary Interventions (PCI). An Angiographic Perfusion Score (APS) combining TIMI flow (TFG) and myocardial perfusion (TMPG) grades before and after PCI can accurately measure both epicardial and myocardial perfusion and predict Major Adverse Cardiac Events (MACE). APS was calculated in 226 (88 ST elevation Myocardial Infarction (STEMI) and 138 Non STEMI) patients. Maximum score being 12, reperfusion was defined as failed: 0-3, partial: 4-9, and full APS: 10-12. Thirty day MACE were observed. APS identified reperfusion significantly more than TMPG alone (STEMI: 50.6% vs 11.8% (p APS group (1.8% vs 22.5%) (p APS detects more low risk reperfused patients, post PCI. Copyright © 2012.

These results remained, adjusting for baseline characteristics and depressive symptoms. These findings testify to the importance of identifying patients with co-occurring risk factors, as they likely require special management in clinical practice in addition...

    To investigate the predictors of and generate a risk prediction method for periprocedural myocardial infarction (PMI) after percutaneous coronary intervention (PCI) using the new PMI definition proposed by the Society for Cardiovascular Angiography and Interventions (SCAI). The SCAI-defined PMI was found to be associated with worse prognosis than the PMI diagnosed by other definitions. However, few large-sample studies have attempted to predict the risk of SCAI-defined PMI. A total of 3,371 patients (3,516 selective PCIs) were included in this single-center retrospective analysis. The diagnostic criteria for PMI were set according to the SCAI definition. All clinical characteristics, coronary angiography findings and PCI procedural factors were collected. Multivariate logistic regression analysis was performed to identify independent predictors of PMI. To evaluate the risk of PMI, a multivariable risk score (PMI score) was constructed with incremental weights attributed to each component variable according to their estimated coefficients. PMI occurred in 108 (3.1%) of all patients. Age, multivessel treatment, at least one bifurcation treatment and total treated lesion length were independent predictors of SCAI-defined PMI. PMI scores ranged from 0 to 20. The C-statistic of PMI score was 0.71 (95% confidence interval: 0.66-0.76). PMI rates increased significantly from 1.96% in the non-high-risk group (PMI score risk group (PMI score ≥ 10) (P risk of PMI after PCI. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  16. An Unusual Case of Spontaneous Left Main Coronary Dissection in A Young Pregnant Woman Treated with Percutaneous Intervention

    Full Text Available Spontaneous coronary artery dissection (SCAD is the spontaneous separation of the coronary artery wall, not iatrogenic or related to trauma. SCAD is an uncommon disease in which the left main coronary involvement is rare. SCAD is commonly nonatherosclerotic, according to predisposing factors (fibromuscular dysplasia, female gender, pregnancy, ecc and precipating factors (intense exercise/emotional stress, vigorous Valsalva type activities, abuse of recreational drugs, ecc. Diagnosis of SCAD is first based on clinical grounds and then confirmed with imaging. Access to different imaging techniques, in particular coronary angiography (CA and intravascular ultrasound (IVUS, is crucial to recognize and manage SCAD in acute care settings. We report an unusual case of high risk acute coronary syndrome due to the left main coronary dissection in a 33 year-old pregnant woman at 19th week of gestation. According to coronary angiography and clinical unstable conditions, LM was successfully treated with a provisional stenting technique. Intra-procedural IVUS was helpful to obtain good stent apposition and confirm the underlying intramural hematoma. Before invasive strategy, the cooperation of the heart team was crucial because we not only considered some protocols to reduce radiation and contrast agent exposure, but also planned a follow up in order to organize the delivery and minimize potential stress conditions and bleeding risk to the fetus. SCAD should not be underestimated when associated to ACS and pregnancy: urgent coronary angiography and bail-out adjunctive imaging are crucial. Improvements in materials and techniques together with a protocol for radiation/contrast media exposure and for antithrombotics drugs administration could make percutaneous interventions feasible and safe in these scenarios.

    Factor VIII Inhibitor Bypassing Activity (FEIBA) can effectively achieve haemostasis in haemophilia patients with inhibitors. Further evaluation of FEIBA in surgical settings is of significant interest considering the relatively limited prospective data published to date. The aim of the study is to evaluate the perioperative efficacy and safety of FEIBA in haemophilia patients with inhibitors. Haemophilia patients with inhibitors who underwent surgical procedures and received FEIBA for perioperative haemostatic control were prospectively enrolled in an open-label, noninterventional, postauthorization study [SURgical interventions with FEIBA (SURF)]. Outcome measures included haemostatic efficacy, safety, FEIBA exposure and blood loss associated with the perioperative use of FEIBA. Thirty-five surgical procedures were performed at 19 centres worldwide in patients with congenital haemophilia A, congenital haemophilia B, or acquired haemophilia A. Haemorrhagic risk was severe in 37.1% (13 of 35) of the procedures, moderate in 25.7% (9 of 35) and mild in 37.1% (13 of 35). One moderate risk surgery was excluded from the efficacy analyses because it did not meet all protocol requirements. Haemostasis was judged to be 'good' or 'excellent' in 91.2% (31 of 34) of surgical procedures and 'fair' in 8.8% (3 of 34). Among the 12 adverse events, three were serious adverse events (SAEs), two of which were unrelated to FEIBA therapy; one SAE, a clot in an arteriovenous fistula, was deemed to be possibly related to therapy. This prospective investigation confirms that FEIBA can be safely and effectively used when performing surgical procedures in haemophilia patients with inhibitors. © 2013 Blackwell Publishing Ltd.

    Positive changes are declared to occur during recent years in management of hospitalized patients with acute coronary syndromes (ACS) in Russia. Most of these changes are related to availability of invasive treatment. But considerable portion of patients (pts) are still treated in hospitals without facilities for invasive myocardial revascularization (noninvasive hospitals - NIHs). Aim of this study was to compare some characteristics of management of ACS in NIHs which participated in ACS registries RECORD (2007-2008, 8 NIHs from 6 cities; n=381) and RECORD-2 (2009-2011, 3 NIHs from 3 cities, n=680). Results. Groups of pts recruited in these NIHs had similar mean age and portion of women (67.6 and 66.5 years, 51.1 and 53.1 % in RECORD-2 and RECORD, respectively, p=0.64). Time from symptoms onset to hospitalization was shorter in RECORD-2 (3.2 vs 4.1 hours for ST-elevation [STE], =0.03; 4.0 vs 6.5 hours for non ST elevation [NSTE] ACS, RECORD-2 NSTEACS pts more had ST depressions (50.6 vs 28.7%, II (15.0 vs 21.6%, p=0.025). No such differences existed among STEACS pts. Thrombolysis was more often used in RECORD-2 (62.6 vs 34.1%, RECORD-2 pts more often received clopidogrel (63.5 vs 18.8%, pRECORD-2 pts were given parenteral anticoagulants (93.4 vs 80.4%, RECORD-2 pts unfractionated heparin was given subcutaneously. Twenty RECORD-2 pts (2.9%) were transferred to invasive hospital but none during first 24 hours. There were no significant differences between registers in hospital mortality (20.0 vs 21.2%, =0.84; 4.2 vs 2.7%, =0.24 in STE and NSTE ACS pts of RECORD-2 and RECORD, respectively). Conclusions. Despite some improvement in management of pts occurring in 2-3 years NIHs mortality in STEACS remained very high. Numerically higher mortality in NSTEACS could be partially attributed to higher risk of RECORD-2 pts.

    In patients with non-ST-segment elevation acute coronary syndromes, inhibition of platelet aggregation (IPA) with a potent P2Y 12 inhibitor, ticagrelor, was inferior to tirofiban infusion at 2 hours, indicating that glycoprotein IIb/IIIa inhibitors are still needed. Ticagrelor and eptifibatide bolus only may maximally inhibit platelet aggregation and decrease bleeding, but IPA with ticagrelor and eptifibatide bolus versus 2-hour infusion is unknown. A total of 70 P2Y 12 -naïve patients, with high-risk non-ST-segment elevation acute coronary syndromes, were randomized to ticagrelor and eptifibatide bolus (group 1) versus ticagrelor and eptifibatide bolus with 2-hour infusion (group 2). Levels of IPA with ADP, thrombin receptor-activating peptide, collagen, and high on-treatment platelet reactivity were measured by light transmission aggregometry at baseline and at 2, 6, and 24 hours after percutaneous coronary intervention in both groups. The primary end point, IPA with ADP 20 μmol/L at 2 hours, was 99.59±0.43% in group 1 versus 99.88±1.0% in group 2 ( P zero at 2, 6, and 24 hours in both groups. IPA levels with ADP, thrombin receptor-activating peptide, and collagen were significantly higher at 2 and 6 hours than at 24 hours in both groups. Periprocedural myocardial infarction was not significantly different between the groups. Hemoglobin level was significantly less at 24 hours versus baseline in group 2 (13.35±1.8 versus 12.38±1.8 g/dL, respectively; P hours, which was associated with no significant hemoglobin drop after percutaneous coronary intervention. This obviates the need for eptifibatide 2-hour infusion and might decrease bleeding complications. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01919723. © 2017 The Authors.

    Full Text Available Testicular cancer is the most common solid tumor among young men. Regimens containing cisplatin and bleomycin in combination with etoposide are used for treatment of non-seminomatous germ cell testicular tumors. Cancer patients are at increased risk of thrombosis. Epidemiological studies have identified chemotherapy as an additional risk factor for a hypercoagulability state and thrombosis. The risk is more pronounced with cisplatin-containing chemotherapy. Thromboprophylaxis with LMWH during chemotherapy has demonstrated to give substantial risk reduction of thromboembolic events. We present a case of acute myocardial infraction during combined chemotherapy with bleomycin, etoposide and cisplatin for testicular cancer under thromboprophylaxis with nadroparin. Emergency coronary angiography revealed total occlusion of the right coronary artery by a thrombus which was successfully removed by aspiration.

Patients and Methods: From September 2009 to March 2012, primary PCI was performed on 70 cases, and the data relating to their catheterization were recorded. Peri-interventional treatment data included PCI with drug-eluting or bare-metal stent or balloon angioplasty alone. Results: The mean age of the patients was 61.34+11.31 years, and 72.9% of them were males. The ratios of patients with diabetes, hypertension and, hyperlipidemia were 61.4%, 71.4%, and 52.9% respectively. In clinical follow-up, total incidence of death was 4.3%, with no death occurring during 30 days. However, 3 patients died after one-year, of which one patient (1.4% had cardiac problem and the other 2 (2.9% died because of non-cardiac reasons. Target vessel revascularization, reinfarction within 30 days, and mechanical complication or stroke were not found in any of the patients. Patients with hypertension (6% and those with LAD ST-elevation myocardial infarction (5% died after one year (P= 0.263 and P= 0.319 respectively. However, no mortality was reported in patients with RCA and LCX ST-elevation myocardial infarction.

    Reports of left-sided brain malignancies among interventional cardiologists have heightened concerns regarding physician radiation exposure. This study evaluated the impact of a suspended lead suit and robotic system on physician radiation exposure during percutaneous coronary intervention (PCI). Real-time radiation exposure data were prospectively collected from dosimeters worn by operating physicians at the head- and chest-level during consecutive PCI cases. Exposures were compared in three study groups: 1) manual PCI performed with traditional lead apparel; 2) manual PCI performed using suspended lead; and 3) robotic PCI performed in combination with suspended lead. Among 336 cases (86.6% manual, 13.4% robotic) performed over 30weeks, use of suspended lead during manual PCI was associated with significantly less radiation exposure to the chest and head of operating physicians than traditional lead apparel (chest: 0.0 [0.1] μSv vs 0.4 [4.0] μSv, probotic PCI performed in combination with suspended lead was 0.0 [0.0] μSv, which was significantly less chest exposure than manual PCI performed with traditional lead (probotic PCI the median head-level exposure was 0.1 [0.2] μSv, which was 99.3% less than manual PCI performed with traditional lead (probotics were observed to result in significantly less radiation exposure to the chest and head of operating physicians during PCI.

    Background Coronary heart disease and acute coronary syndrome remain significant public health problems. The effect of acute coronary syndrome on mortality and morbidity is largely dependent on the time from symptom onset to the time of reperfusion, but patient delay in presenting for treatment is the main reason timely reperfusion is not received. Objectives We tested the effect of an education and counseling intervention on knowledge, attitudes and beliefs about acute coronary syndrome symptoms and the appropriate response to symptoms, and identified patient characteristics associated with changes in knowledge, attitudes and beliefs over time. Methods We conducted a 2-group randomized controlled trial in 3,522 people with coronary heart disease. The intervention group received a 40 minute, one-on-one education and counseling session. The control group received usual care. Knowledge, attitudes and beliefs were measured at baseline, 3 and 12 months using the Acute Coronary Syndrome Response Index and analyzed with repeated measures analysis of variance. Results Knowledge, attitudes and beliefs scores increased significantly from baseline in the intervention group compared to the control group at 3 months, and these differences were sustained at 12 months (p = .0005 for all). Higher perceived control over cardiac illness was associated with more positive attitudes (p<.0005) and higher state anxiety was associated with lower levels of knowledge (p<.05), attitudes (p<.05) and beliefs (p<.0005). Conclusion A relatively short education and counseling intervention increased knowledge, attitudes and beliefs about acute coronary syndrome and response to acute coronary syndrome symptoms in individuals with coronary heart disease. Higher perceived control over cardiac illness was associated with more positive attitudes and higher state anxiety was associated with lower levels of knowledge, attitudes and beliefs about responding to the health threat of possible acute coronary

    Guidelines call for documenting ischemia in patients with stable coronary artery disease prior to elective percutaneous coronary intervention (PCI). To determine the frequency and predictors of stress testing prior to elective PCI in a Medicare population. Retrospective, observational cohort study using claims data from a 20% random sample of 2004 Medicare fee-for-service beneficiaries aged 65 years or older who had an elective PCI (N = 23 887). Percentage of patients who underwent stress testing within 90 days prior to elective PCI; variation in stress testing prior to PCI across 306 hospital referral regions; patient, physician, and hospital characteristics that predicted the appropriate use of stress testing prior to elective PCI. In the United States, 44.5% (n = 10 629) of patients underwent stress testing within the 90 days prior to elective PCI. There was wide regional variation among the hospital referral regions with stress test rates ranging from 22.1% to 70.6% (national mean, 44.5%; interquartile range, 39.0%-50.9%). Female sex (adjusted odds ratio [AOR], 0.91; 95% confidence interval [CI], 0.86-0.97), age of 85 years or older (AOR, 0.83; 95% CI, 0.72-0.95), a history of congestive heart failure (AOR, 0.85; 95% CI, 0.79-0.92), and prior cardiac catheterization (AOR, 0.45; 95% CI, 0.38-0.54) were associated with a decreased likelihood of prior stress testing. A history of chest pain (AOR, 1.28; 95% CI, 1.09-1.54) and black race (AOR, 1.26; 95% CI, 1.09-1.46) increased the likelihood of stress testing prior to PCI. Patients treated by physicians performing 150 or more PCIs per year were less likely to have stress testing prior to PCI (AOR, 0.84; 95% CI, 0.77-0.93). No hospital characteristics were associated with receipt of stress testing. The majority of Medicare patients with stable coronary artery disease do not have documentation of ischemia by noninvasive testing prior to elective PCI.

    Recent studies have reported the efficacy of sheathless percutaneous coronary intervention (PCI) using hydrophilic-coated 5-Fr guiding catheters that are one to two Fr sizes smaller in diameter than the corresponding introducer sheath (virtual 3-Fr PCI). However, the limited number of shapes of hydrophilic-coated guiding catheters occasionally makes them difficult to engage and control. To evaluate the efficacy and feasibility of virtual 3-Fr PCI using standard guiding catheters of various shapes. We identified 35 consecutive patients with stable angina, who underwent virtual 3-Fr PCI using either hydrophilic-coated guiding catheters (Works™, Medikit, Japan) or standard guiding catheters (Heartrail™, Terumo, Japan). Thirty-five patients were identified (63% men; mean age 70 ±13 years). In 2 cases, hydrophilic-coated guiding catheters were exchanged to standard guiding catheters because of difficulty in engaging the target coronary arteries. Ultimately, standard guiding catheters were used in 20 patients (57%) and hydrophilic-coated catheters were used in 15 (43%). One of 20 patients treated with standard guiding catheters and 1 of 15 treated with hydrophilic-coated guiding catheters underwent the 4-in-3 "slender mother and child" PCI technique due to difficulty of stent deployment. There were no differences between the two groups in PCI procedural variables such as procedural time, fluoroscopy time, radiation dose, or contrast dye volume. There were no access site-related complications in this study. These findings indicate that virtual 3-Fr PCI using standard guiding catheters is as efficient and safe as virtual 3-Fr PCI using hydrophilic-coated guiding catheters.

    To determine if fractional flow reserve guided percutaneous coronary intervention (FFR-guided PCI) is associated with reduced ischemic myocardium compared with angiography-guided PCI. Although FFR-guided PCI has been shown to improve outcomes, it remains unclear if it reduces the extent of ischemic myocardium at risk compared with angiography-guided PCI. We evaluated 380 patients (190 FFR-guided PCI cases and 190 propensity-matched controls) who underwent PCI from 2009 to 2014. Clinical, laboratory, angiographic, stress testing, and major adverse cardiac events [MACE] (all-cause mortality, recurrence of MI requiring PCI, stroke) data were collected. Mean age was 63 ± 11 years; the majority of patients were males (76%) and Caucasian (77%). Median duration of follow up was 3.4 [Range: 1.9, 5.0] years. Procedural complications including coronary dissection (2% vs. 0%, P = .12) and perforation (0% vs. 0%, P = 1.00) were similar between FFR-guided and angiography-guided PCI patients. FFR-guided PCI patients had lower unadjusted (14.7% vs. 23.2%, P = .04) and adjusted [OR = 0.58 (95% CI: 0.34-0.98)] risk of repeat revascularization at one year. FFR-guided PCI patients were less likely (23% vs. 32%, P = .02) to have ischemia and had lower (5.9% vs. 21.1%, P guided PCI, FFR-guided PCI results in less repeat revascularization and a lower incidence of post PCI ischemia translating into improved survival, without an increase in complications. © 2018 Wiley Periodicals, Inc.

    The optimal strategy of percutaneous coronary intervention (PCI) for patients with ST-elevation myocardial infarction (STEMI) and multivessel disease (MVD) still remains controversial. This study sought to explore the optimal PCI strategy for those patients. Medline, EMBASE and the Cochrane Controlled Trials Registry were searched for relevant studies. We analyzed the comparison of major adverse cardiac events (MACEs) as the primary end point between the preventive PCI strategy and the culprit only PCI strategy (CV-PCI). The further analysis of two subgroups described as the complete multivessel PCI strategy during primary procedure (CMV-PCI) and the staged PCI strategy (S-PCI) was also performed. Nine randomized trials were identified. The risk of MACEs was reduced significantly regarding to preventive PCI strategy (OR=0.41, 95% CI: 0.31-0.53, Pstrategy. There were lower risks of long-term mortality, reinfarction and repeat revascularization in the preventive PCI group compared to the CV-PCI group (OR=0.41, 95% CI: 0.27-0.62, Pstrategy reduced the incidence of long-term mortality versus CMV-PCI strategy. The preventive PCI is associated with the lower risk of MACEs in STEMI patients with MVD compared to the CV-PCI strategy, and the S-PCI strategy seems to be an optimal choice for these patients rather than the CMV-PCI.

    Full Text Available New research in interventional cardiology has shown the demand for percutaneous coronary interventions (PCI to have increased tremendously. Effective treatment with a lower hospital cost has been the aim of several PCI capable centers. This study aimed to compare the adverse clinical outcomes associated with same day discharge versus overnight stay in the hospital following PCI in a population of randomized patients with stable coronary artery disease (CAD.The National Library of Medicine (MEDLINE/PubMed, the Cochrane Registry of Randomized Controlled Trials and EMBASE databases were searched (from March to June 2016 for randomized trials comparing same-day discharge versus overnight stay in the hospital following PCI. Main endpoints in this analysis included adverse cardiovascular outcomes observed during a 30-day period. Statistical analysis was carried out by the RevMan 5.3 software whereby odds ratios (OR and 95% confidence intervals (CIs were calculated with respect to a fixed or a random effects model.Eight randomized trials with a total number of 3081 patients (1598 patients who were discharged on the same day and 1483 patients who stayed overnight in the hospital were included. Results of this analysis showed that mortality, myocardial infarction (MI and major adverse cardiac events (MACEs were not significantly different between same day discharge versus overnight stay following PCI with OR: 0.22, 95% CI: 0.04-1.35; P = 0.10, OR: 0.68, 95% CI: 0.33-1.41; P = 0.30 and OR: 0.45, 95% CI: 0.20-1.02; P = 0.06 respectively. Blood transfusion and re-hospitalization were also not significantly different between these two groups with OR: 0.64, 95% CI: 0.13-3.21; P = 0.59 and OR: 1.53, 95% CI: 0.88-2.65; P = 0.13 respectively. Similarly, any adverse event, major bleeding and repeated revascularization were also not significantly different between these two groups of patients with stable CAD, with OR: 0.42, 95% CI: 0.05-3.97; P = 0.45, OR: 0

    Objective: To evaluate the relationship between platelet distribution width(PDW) and the extent of coronary artery disease and 2-year outcome in patients received percutaneous coronary artery intervention(PCI) because of stable coronary artery disease(SCAD). Methods: We consecutively enrolled 4 293 patients who received PCI because of SCAD in Fuwai Hospital from Jan 2013 to Dec 2013, patients were followed up for 2 years. Patients were divided into three groups according to tertiles values of PDW as follows: PDW≤11.4%(1 402 patients), 11.4%12.9% (1 450 patients). Major adverse cardiovascular and cerebrovascular events (MACCE) were defined as the occurrence of death, myocardial infarction, target vessel revascularization, intra stent thrombosis and stroke during follow-up. Multivariable logistic regression was used to evaluate the relationship between PDW and the extent of CAD. Multivariable Cox regression was used to evaluate the relationship between PDW and prognosis of SCAD patients. Results: PDW was associated with diabetes mellitus, body mass index, red cell distribution width, mean platelet volume (MPV), platelet counts and glycosylated haemoglobin ( P 0.05). PDW was not correlated with the extent of CAD( P =0.990), SYNTAX score( P =0.721), no-reflow phenomenon after PCI( P =0.978). Multivariable logistic regression also showed no relationship between PDW and extent of CAD ( OR =0.994, 95% CI 0.961-1.029, P =0.73). PDW was found to be an independent risk factor of 2-year cardiac death ( HR =1.242, 95% CI 1.031-1.497, P =0.022), but was not an independent risk factor of all-cause death and MACCE. Conclusions: PDW is not related with the extent of coronary artery disease. PDW is an independent risk factor of 2-year cardiac death, but is not an independent risk factor of all-cause death and MACCE in this patient cohort.

    Second-generation drug-eluting stents (DESs) have shown higher safety and efficacy compared with first-generation DESs. This effect was achieved by improving biocompatibility using an interalia cobalt-chromium construction, thinner stent struts and biodegradable polymers. To assess clinical and angiographic outcomes of patients receiving a novel second-generation cobalt-chromium sirolimus-eluting stent. A total of 424 consecutive patients who received an Alex stent were enrolled in the registry from January to December 2012. The primary outcome measure was the occurrence of 12-month major cardiac adverse events, defined as cases of death, nonfatal myocardial infarction and target lesion revascularization. Quantitative coronary angiography for 240 randomly selected patients was performed by an independent Corelab. The primary endpoint occurred in 31 of 424 patients (7.3%). The rates of death, nonfatal myocardial infarction and target lesion revascularization were 3.3, 2.6 and 3.5%, respectively. According to the definition established by the Academic Research Foundation, definitive and probable stent thrombosis (ST) occurred in 1.6% (7/424) of patients, including six cases of early ST and one case of late ST. The acute device success rate was 98.5%. The ALEX Registry provides evidence for the safety and effectiveness of the study device in a relevant population. Quantitative analysis showed a satisfactory performance of the study device for complex coronary lesions. The 12-month rates of major cardiac adverse event and ST were similar to those of other second-generation DES registries.

    Thymomas are rare malignant epithelial growths, constituting 20% of mediastinal tumours. Resection followed by irradiation may be employed in all thymomas except for stage 1 thymomas. Mediastinal irradiation is associated with coronary artery disease. The mean duration of presentation of post-irradiation coronary artery disease is 16 years (range 3-29 years). In our patient coronary artery disease was found only a year post irradiation. A 55 year old male who presented with complaints of dyspnoea, retrosternal chest pain and heaviness since one year underwent resection for malignant thymoma followed by radiotherapy. He presented with coronary artery disease a year after undergoing mediastinal irradiation. On follow-up, patient was treated successfully by coronary artery bypass graft. This case is an unusual occurrence and suggests that mediastinal irradiation may result in significant coronary artery disease as early as within one year. (author)

    Full Text Available Objectives: This study aims to investigate trends of cardiovascular disease (CVD risk factor profiles over 17 years in percutaneous coronary intervention (PCI patients at the Mayo Clinic. Methods: We performed a time-trend analysis within the Mayo Clinic PCI Registry from 1994 to 2010. Results were the incidence and prevalence of CVD risk factors as estimate by the Framingham risk score. Results: Between 1994 and 2010, 25 519 patients underwent a PCI. During the time assessed, the mean age at PCI became older, but the gender distribution did not change. A significant trend towards higher body mass index and more prevalent hypercholesterolemia, hypertension, and diabetes was found over time. The prevalence of current smokers remained unchanged. The prevalence of ever-smokers decreased among males, but increased among females. However, overall CVD risk according to the Framingham risk score (FRS and 10-year CVD risk significantly decreased. The use of most of medications elevated from 1994 to 2010, except for β-blockers and angiotensin converting enzyme inhibitors decreased after 2007 and 2006 in both baseline and discharge, respectively. Conclusions: Most of the major risk factors improved and the FRS and 10-year CVD risk declined in this population of PCI patients. However, obesity, history of hypercholesterolemia, hypertension, diabetes, and medication use increased substantially. Improvements to blood pressure and lipid profile management because of medication use may have influenced the positive trends.

    Recently developed crowding measures, such as the Emergency Department (ED) Work Index (EDWIN) score, provide a quantifiable measurement of overcrowding in the ED. We sought to determine the association between overcrowding, measured with the EDWIN score, and the time required to initiate percutaneous coronary intervention (PCI) for patients presenting to the ED with acute myocardial infarction (AMI). We retrospectively reviewed the performance improvement (PI) data on all patients presenting to the ED over a 2-month period with chest pain and whose subsequent ECG showed AMI requiring PCI. We recorded the time from patient presentation to the (1) time to first ECG, (2) time to patient arrival in the catheterization laboratory, and (3) time to catheter balloon inflation. We calculated EDWIN scores using data archived from our electronic tracking board and compared the proportion of patients who achieved our established ED goal times between patients presenting during low crowding (EDWIN or = 1.5) conditions. Seventeen patients underwent emergent PCI in the study period. Patients presenting to the ED during periods of low crowding had shorter times to balloon inflation (median of 84 min, IQR 80 to 93 min) than patients presenting to the ED during periods of high crowding (median of 107 min, IQR 94 to 122 min), P = 0.008. Times to first ECG and to arrival in the catheterization laboratory were not significantly different between patients presenting during low and high crowding conditions. Overcrowding appears to be associated with a decreased likelihood of timely treatment for acute AMI in our ED.

    Full Text Available Background. The most important predictors of subsequent patients outcome after acute myocardial infarction (AIM are infarct size, left ventricular ejection fraction, left ventricular volumes and presence and extent of residual myocardial ischemia. All of these variables can be directly determined through scintigraphic approaches. The presence and extent of myocardial ischemia are strong predictors for fatal and nonfatal cardiac events and improve risk statification beyond the information gleaned from clinical variables. Case report. We presented a case of 66-years-old male with myocardial infarction of anteroseptal localization. Myocardial perfusion imaging (MPI detected a large zone of residual ischemia (culprit lesion within infarction zone. It has an important role in risk stratification after myocardial infarction, and indicates subsequent therapeutic decision making, in this case rescue percutaneous coronary intervention (PCI. After PCI we followed the therapy effect by MPI, and we found practically normal perfusion with minimal zone of defect perfusion in the apex. Conclusion. Myocardial perfusion imaging has an important role in the initial evaluation and risk stratification of patients surviving myocardial infarction. It also plays a major role in guiding subsequent therapeutic decision making, and in monitoring the benefits of these therapeutic measures.

    Contrast induced nephropathy (CIN) is the third lead cause of hospital acquired renal failure and was associated with significant morbidity and mortality. We hypothesized that hypertension is an independent risk factor for the development of CIN in patients undergoing elective percutaneous coronary intervention (PCI). The case-control method was used, 138 patients scheduled for elective PCI. We measured serum creatinine at baseline and after 24 hours of the procedure. CIN was defined as arising in serum creatinine of at least 44 μmol/l (0,5 mg/dl) or 25% rise from baseline. All patients received low osmolality nonionic contrast during PCI. Hypertension was defined as self-reported a history of treated or untreated diagnosed high blood pressure. One hundred thirty-eight patients (74,6%) were male, and 35 patients (25,4%) were female. Among the 138 patients, 86 (62,3%) were hypertensive patients whereas 52 (37,7%) were nonhypertensive patients. There was no difference in baseline serum creatinine levels and the amount of contrast media in patient with and without CIN. CIN developed in 42 patients, 39 patients (92,9%) were hypertensive compared to 3 patients (7,1%) without hypertension with p value < 0,05. (Odds ratio 16,8, 95% CI 4.542 - 62,412). This study showed that hypertension was a risk factor for the development of CIN

    Dual antiplatelet therapy with aspirin and a P2Y12 receptor blocker has been proven to reduce subsequent cardiovascular events and in-stent thrombosis in patients undergoing percutaneous coronary intervention. Newer P2Y12 antagonists with faster onset and greater inhibition of platelet activity have improved cardiovascular outcomes but have created uncertainty with the appropriate dosing when switching between agents. Currently, there are no evidence-based guidelines to aid clinicians when switching between P2Y12 receptor blockers. Here we describe two patients that developed in-stent thrombosis when switching from ticagrelor to clopidogrel using a 300 mg clopidogrel loading dose. Both patients presented with ST elevation myocardial infarction and underwent stent placement but then developed in-stent thrombosis 48 hours after switching from ticagrelor to clopidogrel. These cases illustrate the severe consequences of suboptimal platelet inhibition and the need for prospective trials thoroughly powered to assess clinical outcomes in order to determine the most appropriate strategy when switching from ticagrelor to clopidogrel.

    The aim of this study was to evaluate radiation dose and patient discomfort/pain in radial artery access vs femoral artery access in percutaneous coronary intervention (PCI). Dose-area product (DAP) was measured non-randomised for 114 procedures using femoral access and for 55 using radial access. The patients also responded to a questionnaire concerning discomfort and pain during and after the procedure. The mean DAP was 69.8 Gy cm 2 using femoral access and 70.5 Gy cm 2 using radial access. Separating the access site from confounding factors with a multiple regression, there was a 13% reduction in DAP when using radial access (p=0.038). Procedure times did not differ (p=0.81). Bed confinement was much longer in the femoral access group (448 vs 76 min, p=0.000). With femoral access, there was a significantly higher patient grading for chest (p=0.001) and back pain (p=0.003) during the procedure and for access site (p=0.000) and back pain (p=0.000) after the procedure. Thirty-two femoral access patients (28%) were given morphine-type analgesics in the post-procedure period compared to three radial access patients (5%, p=0.001). DAP does not increase when using radial instead of femoral access and the patients grade discomfort and pain much lower when using radial access. Radial access is thus beneficial to use. (orig.)

    Slow flow is a serious complication in primary percutaneous coronary intervention (PCI) and is associated with poor clinical outcomes. Intravascular ultrasound (IVUS)-guided PCI may improve clinical outcomes after drug-eluting stent implantation. The purpose of this study was to seek the factors of slow flow following stent implantation, including factors related to IVUS-guided primary PCI. The study population consisted of 339 ST-elevation myocardial infarction patients, who underwent stent deployment with IVUS. During PCI, 56 patients (16.5%) had transient or permanent slow flow. Multivariate logistic regression analysis showed age (OR 1.04, 95% CI 1.01-1.07, P = 0.01), low attenuation plaque on IVUS (OR 3.38, 95% CI 1.70-6.72, P = 0.001), initial Thrombolysis In Myocardial Infarction (TIMI) flow grade 2 (vs. TIMI 0: OR 0.44, 95% CI 0.20-0.99, P = 0.046), and the ratio of stent diameter to vessel diameter (per 0.1 increase: OR 2.63, 95% CI 1.84-3.77, P flow. A ratio of stent diameter to vessel diameter of 0.71 had an 80.4% sensitivity and 56.9% specificity to predict slow flow. There was no significant difference in ischemic-driven target vessel revascularization between the modest stent expansion (ratio of stent diameter to vessel diameter flow following stent implantation in IVUS-guided primary PCI.

    Post-cardiac injury syndrome (PCIS) is a syndrome characterized by pericardial and/or pleural effusion, triggered by a cardiac injury, usually a myocardial infarction or cardiac surgery, rarely a minor cardiovascular percutaneous procedure. Nowadays, the post-cardiac injury syndrome, is regaining importance and interest as an emerging cause of pericarditis, especially in developed countries, due to a great and continuous increase in the number and complexity of percutaneous cardiologic procedures. The etiopathogenesis seems mediated by the immunitary system producing immune complexes, which deposit in the pericardium and pleura and trigger an inflammatory response. We present the atypical case of a 76-year-old man presenting with a hydro-pneumothorax, low-grade fever and elevated inflammation markers, after two complex percutaneous coronary interventions, executed 30 and 75 days prior. The clinical features of our case are consistent with the diagnostic criteria of PCIS: prior injury of the pericardium and/or myocardium, fever, leucocytosis, elevated inflammatory markers, remarkable steroid responsiveness and latency period. Only one element does not fit with this diagnosis and does not find any further explanation: the air accompanying the pleural effusion, determining a hydro-pneumothorax and requiring a pleural drainage catheter positioning.

    Aspirin remains the mainstay of anti-platelet therapy in cardiac patients. However, if a patient is allergic to aspirin and dual anti-platelet therapy is indicated - such as with percutaneous coronary intervention (PCI), then there is no clear guidance. One possibility is aspirin desensitization. A variety of protocols exist for the rapid desensitization of patients with aspirin allergy. The aim of this survey was to assess current knowledge and practice regarding aspirin desensitization in the UK. We conducted a UK wide survey of all UK 116 PCI centers and obtained complete responses from 40 (35.4%) centers. Of these, just 7 (17.5%) centers had previously desensitised patients; 29 (87.9%) centers suggested a lack of a local protocol prevented them from desensitizing, with 10 (30.3%) unsure of how to conduct desensitization. Only 5 (12.5%) centers had a local policy for aspirin desensitization although 25 (64.1%) units had a clinical strategy for dealing with aspirin allergy; the majority (72%) giving higher doses of thienopyridine class drugs. In the UK, there appears to be no consistent approach to patients with aspirin allergy. Patients undergoing PCI benefit from dual anti-platelet therapy (including aspirin), and aspirin desensitization in those with known allergy may facilitate this. Sustained effort should be placed on encouraging UK centers to use desensitization as a treatment modality prior to PCI rather than avoiding aspirin altogether.

    Women who undergo percutaneous coronary intervention (PCI) are at higher risk of adverse outcomes compared with men, but it is unknown whether gender affects early unplanned rehospitalization. We analyzed 832,753 patients who underwent PCI from 2013 to 2014 in the Nationwide Readmissions Database. We compared gender differences in incidences, predictors, causes, and cost of unplanned 30-day readmissions and examined the effect of co-morbidity. A total of 832,753 men and women who survived the index PCI and were not admitted for a planned readmission were included in the analysis. Overall, 9.4% of patients had an unplanned readmission within 30 days. Thirty-day readmission rates were higher in women compared with men (11.5% vs 8.4%, p exist in rates of unplanned rehospitalization after PCI, where more than 1 in 10 women who undergo PCI are readmitted within 30 days. Gender differences were not observed for causes of noncardiac readmissions, whereas important differences were observed for cardiovascular causes. Copyright © 2018 Elsevier Inc. All rights reserved.

The IMproving Paediatric and Adult Congenital Treatment- registry is a catheterisation registry focussed on paediatric and adult patients with congenital heart disease who are undergoing diagnostic catheterisations and catheter-based interventions. This study reports procedural characteristics and adverse events of patients who have undergone selected catheterisation procedures from January, 2011 to June, 2013. Demographic, clinical, procedural, and institutional data elements were collected at participating centres and entered via either a web-based platform or software provided by the American College of Cardiology-certified vendors, and were collected in a secure, centralised database. For the purpose of this study, procedures that were not classified as one of the 'core' IMproving Paediatric and Adult Congenital Treatment procedures originally chosen for additional data collection were identified and selected for further data analysis. During the time frame of data collection, a total of 8021 cases were classified as other procedures and/or multiple procedures. The most commonly performed case types - isolated or in combination with other procedures - were right ventricular biopsy in 3433 (42.8%), conduit/MPA interventions in 979 (12.3%), and systemic pulmonary artery collateral occlusion in 601 (7.5%). For the whole cohort, adverse events of any severity occurred in 957 (12.0%) cases, whereas major adverse events occurred in 113 (1.4%) cases; six patients (0.1%) died in the catheterisation laboratory. The IMproving Paediatric and Adult Congenital Treatment registry has provided important data on the frequency and spectrum of cardiac catheterisation procedures performed in the present era. For many procedures, more data and work are needed to identify more subtle differences between

    The effects of loading doses of statins on clinical outcomes in patients with acute coronary syndrome (ACS) and planned invasive management remain uncertain. To determine if periprocedural loading doses of atorvastatin decrease 30-day major adverse cardiovascular events (MACE) in patients with ACS and planned invasive management. Multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites in Brazil among 4191 patients with ACS evaluated with coronary angiography to proceed with a percutaneous coronary intervention (PCI) if anatomically feasible. Enrollment occurred between April 18, 2012, and October 6, 2017. Final follow-up for 30-day outcomes was on November 6, 2017. Patients were randomized to receive 2 loading doses of 80 mg of atorvastatin (n = 2087) or matching placebo (n = 2104) before and 24 hours after a planned PCI. All patients received 40 mg of atorvastatin for 30 days starting 24 hours after the second dose of study medication. The primary outcome was MACE, defined as a composite of all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization through 30 days. Among the 4191 patients (mean age, 61.8 [SD, 11.5] years; 1085 women [25.9%]) enrolled, 4163 (99.3%) completed 30-day follow-up. A total of 2710 (64.7%) underwent PCI, 333 (8%) underwent coronary artery bypass graft surgery, and 1144 (27.3%) had exclusively medical management. At 30 days, 130 patients in the atorvastatin group (6.2%) and 149 in the placebo group (7.1%) had a MACE (absolute difference, 0.85% [95% CI, -0.70% to 2.41%]; hazard ratio, 0.88; 95% CI, 0.69-1.11; P = .27). No cases of hepatic failure were reported; 3 cases of rhabdomyolysis were reported in the placebo group (0.1%) and 0 in the atorvastatin group. Among patients with ACS and planned invasive management with PCI, periprocedural loading doses of atorvastatin did not reduce the rate of MACE at 30 days. These findings do not support the routine use

    Limitations in the quality and access of cost data from low-income and middle-income countries constrain the implementation of economic evaluations. With the increasing prevalence of coronary artery disease in Malaysia, cost information is vital for cardiac service expansion. We aim to calculate the hospitalisation cost of percutaneous coronary intervention (PCI), using a data collection method customised to local setting of limited data availability. This is a cross-sectional costing study from the perspective of healthcare providers, using top-down approach, from January to June 2014. Cost items under each unit of analysis involved in the provision of PCI service were identified, valuated and calculated to produce unit cost estimates. Five public cardiac centres participated. All the centres provide full-fledged cardiology services. They are also the tertiary referral centres of their respective regions. The cost was calculated for elective PCI procedure in each centre. PCI conducted for urgent/emergent indication or for patients with shock and haemodynamic instability were excluded. The outcome measures of interest were the unit costs at the two units of analysis, namely cardiac ward admission and cardiac catheterisation utilisation, which made up the total hospitalisation cost. The average hospitalisation cost ranged between RM11 471 (US$3186) and RM14 465 (US$4018). PCI consumables were the dominant cost item at all centres. The centre with daycare establishment recorded the lowest admission cost and total hospitalisation cost. Comprehensive results from all centres enable comparison at the levels of cost items, unit of analysis and total costs. This generates important information on cost variations between centres, thus providing valuable guidance for service planning. Alternative procurement practices for PCI consumables may deliver cost reduction. For countries with limited data availability, costing method tailored based on country setting can be used for

    The number of percutaneous coronary interventions (PCI) is increasing worldwide. Follow-up strategies after PCI are extremely heterogeneous and can greatly affect the cost of medical care. In the present paper, practical advises are provided with respect to a tailored follow-up strategy on the basis of patients' risk profile. Clinical and interventional cardiologists, cardiac rehabilitators, and general practitioners equally contributed to the creation of the present document and defined three follow-up strategies and types and timing of clinical and instrumental evaluations in post-PCI patients.

    Full Text Available Background: Contrast induced kidney injury is an acute renal dysfunction that is secondary to the administration of radio contrast media. The purpose of this study was to evaluate the levels of urotensin-II (UT-II and endothelin-I (ET-I after contrast media administration in patients undergoing percutaneous coronary interventions. Materials and Methods: In this prospective cohort study, we evaluated 78 patients with coronary artery disease who were scheduled for and ultimately underwent percutaneous coronary interventions. As a contrast material, nonionic contrast media was used in various amounts (70-480 mL. Blood and urine samples were obtained to measure U-II, ET-I just before and at the twenty-fourth hour of percutaneous coronary interventions. Results: Compared to baseline, twenty-fourth hour creatinine levels were significantly increased ( P < 0.001. The twenty-fourth hour serum and urine levels of both UT-II and ET-I were also significantly increased compared to baseline ( P < 0.001 for all and 24 th hour serum and urine UT-II (r = 0.322, P = 0.004; r = 0.302, P = 0.007 respectively, ET-I (r = 0.511, P < 0.001; r = 0.266, P = 0.019 respectively levels were significantly correlated with the amount of contrast media. Conclusion: Our study indicates that; increased UT-II and ET-I levels seem to be a consequence of hazardous effects of contrast media on blood vessels and the kidney.

    The Internet could provide a means of delivering secondary prevention programmes to people with coronary heart disease (CHD). To determine the effectiveness of Internet-based interventions targeting lifestyle changes and medicines management for the secondary prevention of CHD. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, in December 2014. We also searched six other databases in October 2014, and three trials registers in January 2015 together with reference checking and handsearching to identify additional studies. Randomised controlled trials (RCTs) evaluating Internet-delivered secondary prevention interventions aimed at people with CHD. Two review authors independently assessed risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. We assessed evidence quality using the GRADE approach and presented this in a 'Summary of findings' table. Eighteen trials met our inclusion criteria. Eleven studies are complete (1392 participants), and seven are ongoing. Of the completed studies, seven interventions are broad, targeting the lifestyle management of CHD, and four focused on physical activity promotion. The comparison group in trials was usual care (n = 6), minimal intervention (n = 3), or traditional cardiac rehabilitation (n = 2).We found no effects of Internet-based interventions for all-cause mortality (odds ratio (OR) 0.27, 95% confidence interval (CI) 0.04 to 1.63; participants = 895; studies = 6; low-quality evidence). There was only one case of cardiovascular mortality in a control group (participants = 895; studies = 6). No incidences of non-fatal re-infarction were reported across any of the studies. We found no effects for revascularisation (OR 0.69, 95% CI 0.37 to 1.27; participants = 895; studies = 6; low-quality evidence).We found no effects for total cholesterol (mean difference (MD) 0.00, 95% CI -0.27 to 0.28; participants = 439; studies = 4; low

    Full Text Available Tim P van de Hoef,1 Martijn Meuwissen,2 Jan J Piek1 1AMC Heartcentre, Academic Medical Center, University of Amsterdam, Amsterdam, 2Amphia Hospital, Breda, the Netherlands Abstract: Fractional flow reserve (FFR is a well-validated clinical coronary physiological parameter derived from the measurement of coronary pressures and has drastically changed revascularization decision-making in clinical practice. Nonetheless, it is important to realize that FFR is a coronary pressure-derived estimate of coronary blood flow impairment. It is thereby not the same as direct measures of coronary flow impairment that determine the occurrence of signs and symptoms of myocardial ischemia. This consideration is important, since the FAME 2 study documented a limited discriminatory power of FFR to identify stenoses that require revascularization to prevent adverse events. The physiological difference between FFR and direct measures of coronary flow impairment may well explain the findings in FAME 2. This review aims to address the physiological background of FFR, its ambiguities, and its consequences for the application of FFR in clinical practice, as well as to reinterpret the diagnostic and prognostic characteristics of FFR in the light of the recent FAME 2 trial outcomes.

    For nearly half a century, coronary artery bypass grafting has been the standard treatment for patients with obstructive left main coronary artery (LMCA) disease. However, there has been considerable evolution in the field of percutaneous coronary intervention, and especially, percutaneous coronary intervention for LMCA disease has been rapidly expanded with adoption of drug-eluting stents. Some, but not all randomized trials, have shown that percutaneous coronary intervention with drug-eluting stents might be a suitable alternative for selected patients with LMCA disease instead of bypass surgery. However, none of previous trials involving early-generation drug-eluting stents was sufficiently powered and comparative trials using contemporary drug-eluting stents were limited. Recently, primary results of 2 new trials of EXCEL (Evaluation of XIENCE Everolimus Eluting Stent Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) and NOBLE (Nordic-Baltic-British Left Main Revascularization Study) were reported. However, these trials showed conflicting results, which might pose uncertainty on the optimal revascularization strategy for LMCA disease. In this article, with the incorporation of a key review on evolution of LMCA treatment, we summarize the similarity or disparity of the EXCEL and NOBLE trials, focus on how they relate to previous trials in the field, and finally speculate on how the treatment strategy may be changed or recommended for LMCA treatment. © 2017 American Heart Association, Inc.

    The routine use of vascular imaging including intravascular ultrasound (IVUS) and optical coherence tomography (OCT) in guiding percutaneous coronary interventions (PCI) is still controversial especially when using drug-eluting stents. A meta-analysis of trials using bare metal stents was previously published. We conducted a meta-analysis of available published trials that compared imaging-guided PCI and angiography-guided PCI in patients undergoing routine PCI only. Trials that enrolled patients with acute coronary syndrome were excluded to decrease heterogeneity. We aimed to study both drug-eluting stents (DES) as well as bare metal stents (BMS). We identified seven randomized controlled trials on IVUS-guided bare metal stents. We also identified three randomized controlled trials on IVUS-guided drug-eluting stents. To improve the power of the drug-eluting stent data, we identified, and included, nine registries that compared IVUS-guided PCI to angiography-guided PCI in the drug-eluting stent era. Nonrandomized registries that included BMS only were excluded as there are multiple previous meta-analyses that studied these patients. Finally, we identified one registry that compared OCT-guided PCI to angiography-guided PCI using either a BMS or a DES. A total of 14,197 patients were studied overall. The meta-analysis was conducted using a random effect model. Imaging guidance was associated with a significantly larger postintervention minimal luminal diameter (SMD: 0.289. 95% CI: 0.213-0.365. P DES patients (odds ratio: 0.810. 95% CI: 0.719-0.912. P DES and BMS patients (odds ratio: 0.782. 95% CI: 0.686-0.890. P DES patients (odds ratio: 0.654. 95% CI: 0.468-0.916.

    Recently, malnutrition has been shown to be related to worse clinical outcomes in patients with heart failure. However, the association between nutritional status and clinical outcomes in patients with coronary artery disease (CAD) remains unclear. We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT; range 0-12, higher = worse, consisting of serum albumin, cholesterol and lymphocytes) score in patients with CAD. The CONUT score was measured on admission in a total of 1987 patients with stable CAD who underwent elective percutaneous coronary intervention (PCI) between 2000 and 2011. Patients were divided into two groups according to their CONUT score (0-1 vs. ≥2). The incidence of major adverse cardiac events (MACE), including all-cause death and non-fatal myocardial infarction, was evaluated. The median CONUT score was 1 (interquartile range 0-2). During the median follow-up of 7.4 years, 342 MACE occurred (17.2%). Kaplan-Meier curves revealed that patients with high CONUT scores had higher rates of MACE (log-rank p Nutritional status assessed by the CONUT score was significantly associated with long-term clinical outcomes in patients with CAD. Pre-PCI assessment of the CONUT score may provide useful prognostic information.

    to study rate and type of life-threatening complications (LC) in patients with ST-Elevation (STE) Acute Coronary Syndrome (ACS) and their relation to implementation of reperfusion measures. Database of the Federal Register of patients with ACS (FRACS) which functioned from 01/01/2009 to 01/01/2014 contains information on 212304 patients with verified diagnosis of ACS. From this pool using random number generator we selected a cohort comprising 10348 patients with STEACS (60% men, mean age 63.5+/-0.1 clinical systolic and diastolic arterial pressure [AP] 135.2+/-0.3 and 81.9+/-0.2 mm Hg, respectively). Killip class was used for determination of degree of acute heart failure. Most frequent forms of LC were heart rhythm disturbances (6.2%) and cardiogenic shock (5.4%). Patients subjected to percutaneous coronary intervention (PCI) including those in whom pharmacoinvasive approach was used had less LC and lower hospital mortality than patients who received only thrombolytic therapy (TLT). Reperfusion measures were administered mostly to patients with class I-II acute heart failure. Hospital mortality was highest (9.47%) among patients not subjected to reperfusion measures and lowest (1.09%) among patients treated with PCI+TLT. FRACS assesses LC in patients with STEACS in the context of implemented reperfusion measures. Data of FRACS can be used by the health service authorities for improvement of medical aid to patients with STEACS.

    There is growing evidence that transradial (TRI) as compared to transfemoral (TFI) percutaneous coronary intervention (PCI) is associated with improved clinical outcome driven by less hemorrhagic complications, in particular in STEMI patients receiving aggressive antithrombotic treatment. Feasibility rate of TRI in STEMI patients has not yet been evaluated. Four-hundred seventy-five consecutive STEMI patients (<12h) without cardiogenic shock were prospectively screened for this all-comer single-centre registry between January 2008 and August 2010. Nine patients were excluded for a priori ineligibility for TRI (forearm shunt for dialysis, prior TRI failure). In the 466 patients enrolled, the operator's opinion about ease of radial puncture was assessed in 4 categories, based on radial pulse quality. Operators were advised not to attempt TRI if ease of puncture was judged "probably difficult/impossible". In case of puncture failure the operator switched immediately to TFI. The mean age of patients was 61 ± 14 (range 27-94) years. Seventy-three percent were men, 17% had diabetes. Nine percent had previous PCI. Glycoprotein inhibitors were used in 70%, and thrombectomy was performed in 70% of patients. PCI was performed using 6F and 5F guiding catheters. Procedural success rate was 98.2% (TIMI flow ≥ 2). In 4.1% (n=19) of patients the operator judged ease of radial puncture "probably difficult/impossible" and no TRI attempt was performed (primary TFI). In the 447 patients with TRI attempt, TRI failure requiring switch to TFI (secondary TFI) was necessary in 22 patients (4.7% of total) following radial puncture failure (n=15), dissection of the radial artery (n=1), prohibitive tortuosities or stenosis of the upper limb axis (n=2), or non-selective position or lack of stability of the guiding catheter (n=2). After the start of the angioplasty procedure, switch from TR to TF was not necessary in any patient. In total, the overall feasibility rate of TRI was 91

    Objective: To study the effect of trans-radial approach (TRA) on achievement of a door-to-balloon time (DBT) of A/sup 2/ 90 minutes in primary PCI percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI). Study Design: Case series. Place and Duration of Study: Armed Forces Institute of Cardiology - National Institute of Heart Diseases (AFIC -NIHD), Rawalpindi, from October 2011 to August 2012. Methodology: Systems goal for door-to-balloon time (DBT - time elapsed between first medical contact and restoration of flow in the infarct related artery (IRA)) was set at < 90 minutes. Procedural success was defined as restoration of TIMI 3 flow in the IRA with less than 30% residual stenosis and discharge from hospital. Non-infarct related arteries were not treated. Bleeding episodes were defined by TIMI definitions. Results: For vascular access for PPCI in a total of 207 patients, TRA was 91.3% (n = 189), transfemoral approach (TFA) 6.3% (n = 13) and brachial 2.4% (n = 5). Males represented 90.3% of cases and 7% were females. Mean age was 55 A +- 10.86 years. Procedural success rate was 97.1%. Mean DBT was 54.1 minutes. DBT was less A/sup 2/ 60 and 90 minutes in 75% and 94.2% of patients respectively. DBT A/sup 2/ 89.50 minutes was achieved in 90% of patients. The difference in DBT between the different access groups was not markedly different between the three groups. There were 6 (2.9%) in-hospital deaths and no major bleeds. Conclusion: TRA for PPCI poses no hindrance to achieving a DBT of < 90 minutes in PPCI for STEMI. Furthermore, the in-hospital mortality rates are acceptable and within rational limits. (author)

    This study aimed to describe the incidence and periprocedural predictors of permanent work disability (PWD) pension among patients ≤50 years old who underwent percutaneous coronary intervention (PCI). Patient records of 910 consecutive patients undergoing PCI at four Finnish hospitals in 2002-2012 were reviewed for baseline and procedural data and late adverse events. Data on permanent work disability (PWD) pension allocation were acquired from the Finnish Centre for Pensions, which governs the statutory pension security in Finland. Mean follow-up was 41 [standard deviation (SD) 31] months. Altogether 103/910 (11.3%) of patients were on PWD by the end of follow-up, 60 (58.3%) for cardiac diagnoses (cumulative freedom from PWD 81% at 7 years). Independent predictors of PWD were post procedural stroke [hazard ratio (HR) 4.7, 95% confidence interval (95% CI) 1.8-11.9], post procedural myocardial infarction (MI) (HR 3.3, 95% CI 1.8-6.0), diabetes (HR 2.0, 95% CI 1.1-3.7), discharge diuretics (HR 3.5, 95% CI 2.1-5.9), and increasing age (HR 1.2, 95% CI 1.1-1.3). Predictors of PWD for cardiac diagnoses were post procedural stroke and MI, discharge diuretics, and use of calcium-channel blockers, diabetes and older age. Patients ≤50 years old undergoing PCI are at a high risk for subsequent permanent disability for cardiac diagnoses. This finding underscores the need for reinforcing adherence to secondary prevention by cardiac rehabilitation and early collaboration with occupational health care professionals.

    Objective: To determine the safety and efficacy of selective thrombus aspiration during Primary Percutaneous Coronary Intervention (PCI). Methods: This observational prospective study was conducted in the catheterization laboratory of a tertiary care cardiovascular centre. A total of 150 consecutive patients who underwent primary PCI were enrolled. Aspiration was done only when thrombus burden was considered significant. After completion of procedure angiographic and electrocardiographic signs were recorded and clinical follow up was documented up to 1 year. Results: No significant difference among the groups was found in age, height, weight and other risk factors like Hypertension, Diabetes Mellitus and Smoking. In general, left anterior descending artery was culprit in 65 % of patients and more than 90 % of culprit vessels had visible thrombus. Multivessel disease was present in 38 % of patients and 22.7% had past history of myocardial infarction. Out of 150 patients 117 (78%) underwent thrombus aspiration. No significant difference was found in ST resolution within 60 minutes (72.6 vs 81.8 %; P<0.285) and myocardial blush grade II and III (41.9 vs 27.3 %; P<0.128). No difference in event free survival was observed among the two groups (80.3 vs 84.8 %; P<0.708) at one year. Conclusion: Selective thrombus aspiration in definite thrombus laden arteries and no aspiration in low or negligible thrombus burden vessels may be a safe and effective strategy in patients undergoing primary PCI. Overall poor risk profile of our patients as compared to western population necessitates further evaluation of this matter in randomized studies. (author)

    Full Text Available Aim: to determine factors associated with In-Stent Restenosis (ISR in patients following Percutaneous Coronary Intervention (PCI. Methods: a retrospective cross-sectional study was conducted using secondary information from medical records of post-PCI patients who underwent follow-up of angiography PCI between January 2009 and March 2014 at The Integrated Cardiovascular Service Unit, Cipto Mangunkusumo Hospital, Jakarta. Angiographic ISR was defined when the diameter of stenosis ≥50% at follow-up angiography including the diameter inside the stent and diameter with five-mm protrusion out of the proximal and distal ends of the stent. Results: there were 289 subjects including 133 subjects with and 156 subjects without ISR. The incidence of ISR in patients using of bare-metal stent (BMS and drug-eluting stent (DES were 61.3% and 40.7%, respectively. Factors associated with ISR are stent-type (OR=4.83, 95% CI 2.51-9.30, stent length (OR=3.71, 95% CI 1.99-6.90, bifurcation lesions (OR=2.43, 95% CI 1.16-5.10, smoking (OR=2.30, 95% CI 1.33-3.99, vascular diameter (OR=2.18, 95% CI 1.2-3.73, hypertension (OR=2.16, 95% CI 1.16-4.04 and diabetes mellitus (OR=2.14, 95% CI 1.23-3.70. Conclusion: stent type, stent length, bifurcation lesions, smoking, vascular diameter, hypertension and DM are factors associated with ISR in patients following PCI. Key words: bare-metal stent; drug-eluting stent; in-stent restenosis.

    Monocyte recruitment to damaged endothelium is enhanced by platelet binding to monocytes and contributes to vascular repair. Therefore, we studied whether the number of platelets per monocyte affects the recurrence of adverse events in patients after percutaneous coronary intervention (PCI). Platelet-monocytes complexes with high and low median fluorescence intensities (MFI) of the platelet marker CD42b were isolated using cell sorting. Microscopic analysis revealed that a high platelet marker MFI on monocytes corresponded with a high platelet density per monocyte while a low platelet marker MFI corresponded with a low platelet density per monocyte (3.4 ± 0.7 vs 1.4 ± 0.1 platelets per monocyte, P=0.01). Using real-time video microscopy, we observed increased recruitment of high platelet density monocytes to endothelial cells as compared with low platelet density monocytes (P=0.01). Next, we classified PCI scheduled patients (N=263) into groups with high, medium and low platelet densities per monocyte and assessed the recurrence of adverse events. After multivariate adjustment for potential confounders, we observed a 2.5-fold reduction in the recurrence of adverse events in patients with a high platelet density per monocyte as compared with a low platelet density per monocyte [hazard ratio=0.4 (95% confidence interval, 0.2-0.8), P=0.01]. We show that a high platelet density per monocyte increases monocyte recruitment to endothelial cells and predicts a reduction in the recurrence of adverse events in patients after PCI. These findings may imply that a high platelet density per monocyte protects against recurrence of adverse events.

    To evaluate the effect of percutaneous coronary intervention (PCI) on left ventricular function in patients with different types of myocardial infarction and to explore the correlation factors for the left ventricular function. A total of 43 patients diagnosed as acute myocardial infarction were enrolled in this study. The perfusion and delayed enhancement magnetic resonance imaging (DE-MRI) was applied to observe the following parameters before the PCI and at month 6 after the procedure: infarct mass, left ventricular ejection fraction (LVEF) and abnormal wall motion score. The subjects were divided into the following three groups by the transmural extent of myocardial infarction manifested in the DE-MRI: the transmural enhancement group, the nontransmural group and the mixed group. Laboratory test was done to detect the level of endothelin (ET), matrix metal enzyme 9 (MMP-9) and high sensitive C reactive protein (hsCRP) before PCI and at month 6 after the procedure. The t test was used to compare the differences among the groups and the multiple regression analysis was taken to explore the correlation factors for the left ventricular function. Compared with the parameters before PCI, the infarct mass after PCI significantly decreased in the nontransmural group and the mixed group [(4.0 ± 2.9) g/cm(3) vs (9.8 ± 5.6) g/cm(3) and (6.0 ± 3.5) g/cm(3) vs (11.8 ± 6.2)g/cm(3), all P infarct mass was an independent correlation factor for LVEF before PCI (RR = 0.318, P myocardial infarction, which is correlated with the amount of survival myocardium and the inflammatory factors.

    Delayed arrival to a primary percutaneous coronary intervention (PPCI)-capable hospital following ST-elevation myocardial infarction (STEMI) is associated with poorer outcome. The influence of patient characteristics on delayed presentation during STEMI is unknown. This was a retrospective observational study. Patients presenting for PPCI from March 2008 to November 2011 in the north of England (Northumbria, Tyne and Wear) were included. The outcomes were self-presentation to a non-PPCI-capable hospital, symptom to first medical contact (STFMC) time, total ischaemic time and mortality during follow-up. STEMI patients included numbered 2297; 619 (26.9%) patients self-presented to a non-PPCI-capable hospital. STFMC of >30 min and total ischaemic time of >180 min was present in 1521 (70.7%) and 999 (44.9%) cases, respectively. Self-presentation was the strongest predictor of prolonged total ischaemic time (odds ratio, OR (95% confidence interval, CI): 5.05 (3.99-6.39)). Married patients (OR 1.38 (1.10-1.74)) and patients living closest to an Emergency Room self-presented more commonly (driving time (vs. ≤10 min) 11-20 min OR 0.66 (0.52-0.83), >20 minutes OR 0.46 (0.33-0.64). Unmarried females waited longest to call for help (OR vs. married males 1.89 (1.29-2.78) and experienced longer total ischaemic times (OR 1.51 (1.10-2.07)). Married patients had a borderline association with lower mortality (hazard ratio 0.75 (0.53-1.05), p=0.09). Unmarried female patients had the longest treatment delays. Married patients and those living closer to an Emergency Room self-present more frequently. Early and exclusive use of the ambulance service may reduce treatment delay and improve STEMI outcome. © The European Society of Cardiology 2014.

    Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could predict PMI in PCI. This study included 370 patients treated with PCI for stable angina pectoris. AVC was defined as bright echoes >1 mm on one or more cusps of the aortic valve on ultrasound cardiography (UCG). PMI was defined as an increase in high-sensitivity troponin T level of >5 times the upper normal limit (>0.070 ng/ml) at 24 hours after PCI. AVC was detected in 45.9% of the patients (n=170). The incidence of PMI was significantly higher in the patients with AVC than in those without AVC (43.5% vs 21.0%, p<0.001). The presence of AVC independently predicted PMI after adjusting for other significant variables (odds ratio 2.26, 95% confidence interval 1.37-3.74, p=0.002). Other predictors were male sex, age, estimated glomerular filtration rate, and total stent length. Furthermore to predict PMI, adding AVC to the established risk factors significantly improved the area under the receiver operating characteristic curves, from 0.68 to 0.72, of the PMI prediction model (p=0.025). The presence of AVC detected in UCG could predict the incidence of PMI.

    Clinical trials suggest that residual risks remain for coronary artery disease (CAD) during low-density lipoprotein cholesterol (LDL-C) lowering therapy. We aimed to investigate the role of exogenous lipids in the prognosis of CAD after percutaneous coronary intervention (PCI). A total of 145 patients with CAD, who underwent elective PCI, and 82 non-CAD (control) patients were enrolled in this study. CAD patients underwent follow-up coronary angiography 6-9 months after PCI, and were classified into three groups: 1) patients who showed in-stent restenosis (ISR) in the original stented segment, 2) patients with other non-target coronary atherosclerotic lesions (de novo), and 3) patients with neither ISR nor a de novo lesion. Biochemical analyses were performed on fasting serum samples at the time of follow-up coronary angiography. Despite the controlled serum LDL-C levels, CAD patients with statin showed elevated cholesterol absorption marker campesterol/total cholesterol (TC), synthesis marker lathosterol/TC, campesterol/lathosterol ratio, and apolipoprotein B48 (apoB48) concentration compared with non-CAD patients. The high campesterol/TC, campesterol/lathosterol ratio, and apoB48 concentration were associated with de novo lesion progression after PCI. In stepwise multivariate logistic regression analysis, campesterol/TC and apoB48 concentrations were independent risk factors for de novo lesion progression in statin-treated CAD patients after PCI. The increase of cholesterol absorption marker and apoB48 concentration may lead to the progression of de novo lesions, and these markers may represent a residual risk during statin treatment after PCI.

    Coronary lipid core plaque may be associated with the incidence of subsequent cardiovascular events. We analyzed outcomes of 239 patients who underwent near-infrared spectroscopy (NIRS) coronary imaging between 2009-2011. Multivariable Cox regression was used to identify variables independently associated with the incidence of major adverse cardiovascular events (MACE; cardiac mortality, acute coronary syndromes (ACS), stroke, and unplanned revascularization) during follow-up. Mean patient age was 64±9years, 99% were men, and 50% were diabetic, presenting with stable coronary artery disease (61%) or an acute coronary syndrome (ACS, 39%). Target vessel pre-stenting median lipid core burden index (LCBI) was 88 [interquartile range, IQR 50-130]. Median LCBI in non-target vessels was 57 [IQR 26-94]. Median follow-up was 5.3years. The 5-year MACE rate was 37.5% (cardiac mortality was 15.0%). On multivariable analysis the following variables were associated with MACE: diabetes mellitus, prior percutaneous coronary intervention performed at index angiography, and non-target vessel LCBI. Non-target vessel LCBI of 77 was determined using receiver-operating characteristic curve analysis to be a threshold for prediction of MACE in our cohort. The adjusted hazard ratio (HR) for non-target vessel LCBI ≥77 was 14.05 (95% confidence interval (CI) 2.47-133.51, p=0.002). The 5-year cumulative incidence of events in the above-threshold group was 58.0% vs. 13.1% in the below-threshold group. During long-term follow-up of patients who underwent NIRS imaging, high LCBI in a non-PCI target vessel was associated with increased incidence of MACE. Published by Elsevier Inc.

    The prognostic impact of nutritional status in ST-elevation myocardial infarction (STEMI) patients is poorly understood. We used the controlling nutritional status (CONUT) score and the prognostic nutritional index (PNI) score on outcomes of 945 patients with acute STEMI undergoing primary percutaneous coronary intervention with stent. During a median follow-up of 2years (1-3.3years, interquartile range), 56 patients (5.9%) died for all-cause of death. In the dead group, the CONUT and PNI scores were more severe than in the alive group. Elderly patients (≥71years) had nutritional indices more serious than patients nutritional status evaluated by the CONUT score, in addition to other comorbidities, can affect the prognosis in elderly patients. These results suggest a personalized nutritional treatment as well as an accurate assessment of the appropriateness of lipid-lowering treatment after coronary revascularization.

    Myocardial ischemia is recognized as an important mechanism increasing the risk for cardiovascular events in both symptomatic and asymptomatic patients. In addition to obstructive coronary diseases, systemic inflammation, macro- and microvascular function are additional important mechanisms contributing to the ischemic myocardium. Accumulating evidence indicates that coronary flow reserve (CFR) is a quantitative measurement of ischemia including integrated information on structure and function of the coronary artery at all levels. Not surprisingly, CFR has been shown to confer strong prognostic value for hard cardiovascular (CV) events in a number of relevant patient cohorts. Using high-resolution imaging, it is now possible to study coronary arteries from mouse to man. Therefore, CFR may be an important translational tool to risk-stratify patients and to perform both preclinical and clinical proof-of-concept studies before investing in large-scale outcome trials, thus improving the translational value for novel CV targets.

    Background: Reports of left-sided brain malignancies among interventional cardiologists have heightened concerns regarding physician radiation exposure. This study evaluated the impact of a suspended lead suit and robotic system on physician radiation exposure during percutaneous coronary intervention (PCI). Methods: Real-time radiation exposure data were prospectively collected from dosimeters worn by operating physicians at the head- and chest-level during consecutive PCI cases. Exposures were compared in three study groups: 1) manual PCI performed with traditional lead apparel; 2) manual PCI performed using suspended lead; and 3) robotic PCI performed in combination with suspended lead. Results: Among 336 cases (86.6% manual, 13.4% robotic) performed over 30 weeks, use of suspended lead during manual PCI was associated with significantly less radiation exposure to the chest and head of operating physicians than traditional lead apparel (chest: 0.0 [0.1] μSv vs 0.4 [4.0] μSv, p < 0.001; head: 0.5 [1.9] μSv vs 14.9 [51.5] μSv, p < 0.001). Chest-level radiation exposure during robotic PCI performed in combination with suspended lead was 0.0 [0.0] μSv, which was significantly less chest exposure than manual PCI performed with traditional lead (p < 0.001) or suspended lead (p = 0.046). In robotic PCI the median head-level exposure was 0.1 [0.2] μSv, which was 99.3% less than manual PCI performed with traditional lead (p < 0.001) and 80.0% less than manual PCI performed with suspended lead (p < 0.001). Conclusions: Utilization of suspended lead and robotics were observed to result in significantly less radiation exposure to the chest and head of operating physicians during PCI. - Highlights: • Use of suspended lead during manual PCI reduced cranial radiation among operators by 97%. • Robotic PCI reduced cranial radiation among operators by 99%. • Suspended lead and robotics together achieved the lowest levels of radiation exposure.

    Outcomes of percutaneous coronary intervention (PCI) versus medical therapy (MT) in the management of stable ischemic heart disease (SIHD) remain controversial, with some but not all studies showing improved results in patients with ischemia. We sought to elucidate whether PCI improves mortality compared to MT in patients with objective evidence of ischemia (assessed using noninvasive imaging or its invasive equivalent). We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing PCI to MT in patients with SIHD. To maintain a high degree of specificity for ischemia, studies were only included if ischemia was defined on the basis of noninvasive stress imaging or abnormal fractional flow reserve. The primary outcome was all-cause mortality. We identified 3 RCTs (Effects of Percutaneous Coronary Interventions in Silent Ischemia After Myocardial Infarction II, Fractional Flow Reserve versus Angiography for Multivessel Evaluation 2, and a substudy of the Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation trial) enrolling a total of 1,557 patients followed for an average of 3.0 years. When compared with MT in this population of patients with objective ischemia, PCI was associated with lower mortality (hazard ratio 0.52, 95% confidence interval 0.30 to 0.92, p=0.02). There was no evidence of study heterogeneity or bias among included trials. In this meta-analysis of published RCTs, PCI was shown to have a mortality benefit over MT in patients with SIHD and objective assessment of ischemia using noninvasive imaging or its invasive equivalent. In conclusion, this study provides insight into the management of a higher-risk SIHD population that is the focus of the ongoing International Study of Comparative Health Effectiveness with Medical and Invasive Approaches trial.

The QoL was assessed using the MacNew Heart Disease Health-Related Quality of Life questionnaire. The group of females scored lower in all the domains of the MacNew Heart Disease Health-Related Quality of Life questionnaire in the initial measurement (B1, in the measurement after 6 months (B2, and in the long-term follow-up measurement (36 months – B3. Despite the fact that both groups achieved improved QoL, its values were higher in the males. The average growth rate of the QoL score in the period from the sixth month to 36th month was higher in females than in males. In the univariate and multivariate analyses, significant independent predictors with a negative influence on the long-term QoL score included female sex (Ρ=−0.190, β=−0.21, age >60 years (Ρ=−0.255, β=−0.186, and diabetes (Ρ=−0.216, β=−0.216.Conclusion: In a 36-month follow-up of ACS patients treated with PCI, there were no statistically significant differences in QoL between sexes. In the entire cohort, there was improvement in QoL, which was higher in the case of the females studied. For the entire group, significant independent determinants of lower QoL 3

    There is a paucity of diagnostic and therapeutic facilities in Nigeria to confirm coronary artery disease and offer appropriate interventional therapy. There is now a private cardiac catheterization laboratory in Lagos but as there are no sustained Open Heart Surgery programmes, percutaneous coronary interventions are currently being performed without surgical backup. This study was designed to assess results of stand-alone percutaneous coronary intervention (PCI) as currently practiced in Lagos, Nigeria. This cross-sectional study was conducted between July 2009 and July 2012. The study included all patients that underwent PCI in Lagos. Data was extracted from a prospectively maintained database. Coronary artery disease was confirmed in 80 (52.6%) of 152 Nigerians referred with a diagnosis of Ischaemic Heart Disease. There were 53 males (66.2%) and 27 females (33.8%). The average age was 60.3 +/-9.6 years and average euroscore was 4.5 +/-3.1. Of the 80 patients, 77 (96.3%) had significant stenoses and were candidates for revascularization. Distribution of significant stenoses was one in 32 patients (41.5%), two in 11 patients (14.3%), three in 19 patients (24.7%), four in 13 patients (16.9%) and five in 2 patients (2.6%). PCI was performed in 48 (62.3%) of the patients eligible for revascularization as the coronary anatomy in the remaining patients was not suitable for PCI. The indication for PCI was for myocardial infarction or unstable angina in 39 patients (81.2%). PCI was performed with PTCA plus stenting in 41 patients (85.4%) and with PTCA alone in 7 patients (14.6%) with good angiographic results. Overall 29 of the 48 patients (60.4%) had complete revascularization of significant stenoses. Complications of PCI were bleeding that required blood transfusion in 1 patient (2.1%), minor femoral haematomas in 2 patients (4.2%), and a major adverse clinical event in 1 patient (2.1%). A stand-alone PCI programme has been developed in Lagos, Nigeria. Both elective

    Background The child-oriented dietary intervention given in the prospective Special Turku Coronary Risk Factor Intervention Project (STRIP) has decreased the intake of saturated fat and lowered serum cholesterol concentration in children from infancy until early adulthood. In this study, we investigated whether the uniquely long-term child-oriented intervention has affected also secondarily parental diet and cardio-metabolic risk factors. Methods The STRIP study is a longitudinal, randomized infancy-onset atherosclerosis prevention trial continued from the child's age of 8 months to 20 years. The main aim was to modify the child's diet towards reduced intake of saturated fat. Parental dietary intake assessed by a one-day food record and cardio-metabolic risk factors were analysed between the child's ages of 9-19 years. Results Saturated fat intake of parents in the intervention group was lower [mothers: 12.0 versus 13.9 daily energy (E%), p cardio-metabolic risk factors were similar in the study groups. Conclusions Child-oriented dietary intervention shifted the dietary fat intakes of parents closer to the recommendations and tended to decrease total and low-density lipoprotein cholesterol in the intervention mothers. Dietary intervention directed to children benefits also parents.

    The present study examined the association between Multicenter CTO Registry in Japan (J-CTO) score in predicting failure of percutaneous coronary intervention (PCI) correlating with the estimated duration of chronic total occlusion (CTO). The J-CTO score does not incorporate estimated duration of the occlusion. This was an observational retrospective study that involved all consecutive procedures performed at a single tertiary-care cardiology center between January 2009 and December 2014. A total of 174 patients, median age 59.5 years (interquartile range [IQR], 53-65 years), undergoing CTO-PCI were included. The median estimated occlusion duration was 7.5 months (IQR, 4.0-12.0 months). The lesions were classified as easy (score = 0), intermediate (score = 1), difficult (score = 2), and very difficult (score ≥3) in 51.1%, 33.9%, 9.2%, and 5.7% of the patients, respectively. Failure rate significantly increased with higher J-CTO score (7.9%, 20.3%, 50.0%, and 70.0% in groups with J-CTO scores of 0, 1, 2, and ≥3, respectively; PJ-CTO score predicted failure of CTO-PCI independently of the estimated occlusion duration (P=.24). Areas under receiver-operating characteristic curves were computed and it was observed that for each occlusion time period, the discriminatory capacity of the J-CTO score in predicting CTO-PCI failure was good, with a C-statistic >0.70. The estimated duration of occlusion had no influence on the J-CTO score performance in predicting failure of PCI in CTO lesions. The probability of failure was mainly determined by grade of lesion complexity.

    Full Text Available Serum alkaline phosphatase (ALP has been shown to be a prognostic factor in several subgroups of patients due to its promotion of vascular calcification. However, the prognostic impact of serum ALP level in ST-segment elevation myocardial infarction (STEMI patients with a relatively low calcification burden has not been determined. We aimed to investigate the association of ALP level measured at time of presentation on clinical outcomes in patients with STEMI requiring primary percutaneous coronary intervention (PCI.A total of 1178 patients with STEMI undergoing primary PCI between 2007 and 2014 were retrospectively enrolled from the INTERSTELLAR registry and classified into tertiles by ALP level (83 IU/L. The primary study outcome was a major adverse cardiac or cerebrovascular event (MACCE, defined as the composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and ischemia-driven revascularization.Median follow-up duration was 25 months (interquartile range, 10-39 months. The incidence of MACCE significantly increased as ALP level increased, that is, for the 83 IU/L tertiles incidences were 8.7%, 11.7%, and 15.7%, respectively; p for trend = 0.003. After adjustment for potential confounders, the adjusted hazard ratios for MACCE in the middle and highest tertiles were 1.69 (95% CI 1.01-2.81 and 2.46 (95% CI 1.48-4.09, respectively, as compared with the lowest ALP tertile.Elevated ALP level at presentation, but within the higher limit of normal, was found to be independently associated with higher risk of MACCE after primary PCI in patients with STEMI.

    Successful percutaneous coronary intervention (PCI) of the occluded infarct-related artery (IRA) in latecomers may improve long-term survival mainly by reducing left ventricular remodeling. It is not clear whether inhibition of renin-angiotensin system (RAS) brings additional better clinical outcomes in this specific population subset. Between January 2008 and June 2013, 669 latecomer patients with acute ST-segment elevation myocardial infarction (STEMI) (66.2±12.1 years, 71.0% males) in Korea Acute Myocardial Infarction Registry (KAMIR) who underwent a successful PCI were enrolled. The study population underwent a successful PCI for a totally occluded IRA. They were divided into two groups according to whether they were prescribed RAS inhibitors at the time of discharge: group I (RAS inhibition, n=556), and group II (no RAS inhibition, n=113). During the one-year follow-up, major adverse cardiac events (MACE), which consist of cardiac death and myocardial infarction, occurred in 71 patients (10.6%). There were significantly reduced incidences of MACE in the group I (hazard ratio=0.34, 95% confidence interval 0.199-0.588, p=0.001). In subgroup analyses, RAS inhibition was beneficial in patients with male gender, history of hypertension or diabetes mellitus, and even in patients with left ventricular ejection fraction (LVEF) ≥40%. In the baseline and follow-up echocardiographic data, benefit in changes of LVEF and left ventricular end-systolic volume was noted in group I. In latecomers with STEMI, RAS inhibition improved long-term clinical outcomes after a successful PCI, even in patients with low risk who had relatively preserved LVEF.

    To evaluate whether the maximum radiation dose to the patient's skin (MSD) can be estimated during percutaneous coronary intervention (PCI) procedures, we investigated the relationship between the MSD and fluoroscopic time, dose-area product (DAP), and body weight, separately analyzing the relationships for different target vessels. Many cases of skin injury caused by excessive radiation exposure during cardiac intervention procedures have been reported. However, real-time maximum-dose monitoring of the skin is unavailable for many cardiac intervention procedures. We studied 197 consecutive PCI procedures that involved a single target vessel and were conducted. The DAP was measured, and the MSD was calculated by a skin-dose mapping software program (Caregraph). The target vessels of the PCI procedures were divided into four groups based on the AHA classification system: AHA 5-10, left anterior descending artery domain (LAD), AHA 11-15, left circumflex artery domain (LCx), AHA 1-3 = R 1-3, and AHA 4 = R 4. The correlation coefficient (r) between the MSD and fluoroscopic time was higher for the right coronary artery (RCA) vessels (R 1-3, 0.852; R 4, 0.715) than for the left coronary artery (LCA) vessels (LAD, 0.527; LCx, 0.646), and the r value between the MSD and DAP was higher for the RCA vessels (R 1-3, 0.871; R 4, 0.898) than for the LCA vessels (LAD, 0.628; LCx, 0.694). Similarly, the correlation coefficient between the MSD and weight x fluoroscopic time (WFP) was higher for the RCA vessels (R 1-3, 0.874; R 4, 0.807) than for the LCA vessels (LAD, 0.551; LCx, 0.735). The DAP and WFP can be used to estimate the MSD during PCI in the RCA but not in the LCA, especially the LAD.

    Third-generation drug-eluting metal stents are the gold standard for treatment of coronary artery disease. The permanent metallic caging of the vessel, however, can result in limited vasomotion, chronic inflammation, and late expansive remodeling, conditions that can lead to late and very late stent thrombosis. The development of bioresorbable scaffolds (BRSs) promises advantages over metal stents due to complete biodegradation within 2-4years. Theoretically, since vessel scaffolding is temporary and no permanent implant remains in the vessel, BRSs, as opposed to metal stents, once degraded would no longer be potential triggers for stent-related adverse events or side effects. The short- and long-term outcome after implantation of an everolimus-eluting, poly-L-lactic acid-based bioresorbable scaffold system (ABSORB, Abbott Vascular, Santa Clara, CA, USA) in the world-wide greatest all-comers cohort will be evaluated in the prospective, non-interventional, multicenter German-Austrian ABSORB RegIstRy (GABI-R). GABI-R will include over 5000 patients from about 100 study sites in Austria and Germany. Safety endpoints such as cardiac death, myocardial infarction, and clinically driven percutaneous or surgical target lesion and vessel revascularization will be evaluated during hospitalization and in the follow-up period (minimum of 5years). Although two randomized controlled trials and several registries have documented safety and efficacy as well as non-inferiority of this everolimus-eluting ABSORB device compared with drug-eluting metal stents, the current knowledge regarding clinical application, treatment success, and long-term safety of using this BRS in daily routine is limited. Thus, the goal of GABI-R is to address this lack of information. Copyright © 2015 Elsevier Inc. All rights reserved.

    It is unknown whether using a single guiding catheter for both nonculprit and culprit vessel angiography and intervention during transradial primary percutaneous coronary intervention (PCI) is feasible. This single-center study enrolled 242 consecutive patients with ST segment elevation myocardial infarction (STEMI) who received primary PCI. Among them, 102 patients received primary PCI via transfemoral approach (TFI), 109 patients received primary PCI via transradial approach using conventional technique (Conventional TRI), and 31 underwent primary TRI using a single guiding catheter (Single Guiding TRI). The catheter used for this purpose was 6 Fr RM® 3.5 guiding catheter. Using a single guiding catheter, both coronary artery angiograms and intervention were successful in 30 of 31 patients (96.7%). Needle-to-balloon time (from puncture to first balloon) and door-to-balloon (D2B) time were similar between TFI and Conventional TRI groups and significantly lower in the Single Guiding TRI group (13.8 [TFI] and 14.1 [Conventional TRI] vs. 7.6 minutes, P Guiding TRI group from 51.0% for TFI and 49.5% for Conventional TRI to 74.2% (P = 0.023). Primary transradial PCI using a single guiding catheter is feasible and highly successful and might allow timely restoration of blood flow in infarct-related artery. ©2012, Wiley Periodicals, Inc.

    Malnutrition has been identified as an important predictor of poor clinical outcomes in patients with heart failure. The aim of this study is to examine the prognostic impact of nutritional status in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). The impact of nutrition, assessed using the geriatric nutritional risk index (GNRI) calculated by serum albumin and body mass index, was evaluated in 2,853 patients with CAD who underwent their first PCI between 2000 and 2011. Patients were assigned to tertiles based on their GNRI levels. The incidences of all-cause death and cardiac death were assessed. The median GNRI values were 101 (interquartile range 95 to 106). Lower GNRI levels were associated with older age and higher prevalence of acute coronary syndrome and chronic kidney disease. During the median follow-up period of 7.4 years, Kaplan-Meier curves showed ongoing divergence in rates of mortality among tertiles (GNRI nutritional status was associated with long-term clinical outcomes in CAD patients after PCI. Evaluation of GNRI carries important prognostic information and may guide the therapeutic approach to such patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aim of the study was to determine the safety and efficacy of a novel femoral artery closure device (StarClose, Abbott Vascular Devices, Redwood City, CA) following percutaneous coronary intervention employing aspirin, heparin, and glycoprotein (GP) IIb/IIIa inhibition. A prospective nonrandomized single-center pilot study of the StarClose device included a subset of patients undergoing percutaneous coronary intervention utilizing GP IIb/IIIa inhibitors. Those that fulfilled the inclusion criteria (age < 80, no periprocedural haematoma, puncture above the superficial femoral and profunda femoralis artery bifurcation, no significant femoral artery disease) underwent closure of the femoral artery puncture site with a StarClose device immediately on completion of the procedure. Time to hemostasis (TTH), bleeding, mobilization, and short-term clinical follow-up data were collected, and an ultrasound scan of the femoral artery was performed 2 weeks later. Twenty-five patients were recruited, of whom 23 underwent percutaneous coronary intervention (PCI). Their mean age was 58 +/- 12 years, 84% were male, and 63% had unstable angina. All were on aspirin 100-150 mg daily and all PCI patients received i.v. heparin 4-10,000 units at commencement of the procedure and clopidogrel 600 mg on completion. Two patients were on a tirofiban infusion and 23 received a double bolus of eptifibatide, each 0.18 mg/kg, separated by 10 min. The procedural success was 100% and device success 23/25 (92%), with 1 failure due to technical error. The median device delivery time was 36 sec (range, 11-178) and median TTH 37 sec (range, 10-509 sec). There were no major adverse events. In 10 patients, a moderate amount of tract ooze required a short period of adjunctive manual compression. Follow-up ultrasound femoral artery scans revealed no compromise of the vessel lumen.

    Full Text Available Anaphylaxis is a sudden-onset, severe hypersensitivity reaction that can be potentially fatal. It can often transition to refractory hemodynamic instability, eventually resulting in death. Stress-related cardiomyopathies (SRCs have multifactorial etiologies, including being linked to excessive catecholamine release in periods of intense stress. This novel case report recounts a SRC caused by contrast-induced anaphylaxis within 1 hour post percutaneous coronary intervention. Both acutely life-threatening conditions may occur simultaneously and are implicated with devastating complications. Further research is required to understand this cardiac-neuroaxis interplay in SRC to identify risk factors and develop management strategies.

    In medical and surgical intensive care units, clinical risk prediction models for readmission have been developed; however, studies reporting the risks for cardiovascular intensive care unit (CVICU) readmission have been methodologically limited by small numbers of outcomes, unreported measures of calibration or discrimination, or a lack of information spanning the entire perioperative period. The purpose of this study was to derive and validate a clinical prediction model for CVICU readmission in cardiac surgical patients. A total of 10,799 patients more than or equal to 18 years in the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry who underwent cardiac surgery (coronary artery bypass or valvular surgery) between 2004 and 2012 and were discharged alive from the first CVICU admission were included. The full cohort was used to derive the clinical prediction model and the model was internally validated with bootstrapping. Discrimination and calibration were assessed using the AUC c index and the Hosmer-Lemeshow tests, respectively. A total of 479 (4.4%) patients required CVICU readmission. The mean CVICU length of stay (19.9 versus 3.3 days, P prediction model had robust discrimination and calibration in the derivation cohort (AUC c index = 0.799; Hosmer-Lemeshow P = 0.192). The validation point estimates and confidence intervals were similar to derivation model. In a large population-based dataset incorporating a comprehensive set of perioperative variables, we have derived a clinical prediction model with excellent discrimination and calibration. This model identifies opportunities for targeted therapeutic interventions aimed at reducing CVICU readmissions in high-risk patients.

    Objective We hypothesised that, compared with culprit-only primary percutaneous coronary intervention (PCI), additional preventive PCI in selected patients with ST-elevation myocardial infarction with multivessel disease would not be associated with iatrogenic myocardial infarction, and would be associated with reductions in left ventricular (LV) volumes in the longer term. Methods In the preventive angioplasty in myocardial infarction trial (PRAMI; ISRCTN73028481), cardiac magnetic resonance (CMR) was prespecified in two centres and performed (median, IQR) 3 (1, 5) and 209 (189, 957) days after primary PCI. Results From 219 enrolled patients in two sites, 84% underwent CMR. 42 (50%) were randomised to culprit-artery-only PCI and 42 (50%) were randomised to preventive PCI. Follow-up CMR scans were available in 72 (86%) patients. There were two (4.8%) cases of procedure-related myocardial infarction in the preventive PCI group. The culprit-artery-only group had a higher proportion of anterior myocardial infarctions (MIs) (55% vs 24%). Infarct sizes (% LV mass) at baseline and follow-up were similar. At follow-up, there was no difference in LV ejection fraction (%, median (IQR), (culprit-artery-only PCI vs preventive PCI) 51.7 (42.9, 60.2) vs 54.4 (49.3, 62.8), p=0.23), LV end-diastolic volume (mL/m2, 69.3 (59.4, 79.9) vs 66.1 (54.7, 73.7), p=0.48) and LV end-systolic volume (mL/m2, 31.8 (24.4, 43.0) vs 30.7 (23.0, 36.3), p=0.20). Non-culprit angiographic lesions had low-risk Syntax scores and 47% had non-complex characteristics. Conclusions Compared with culprit-only PCI, non-infarct-artery MI in the preventive PCI strategy was uncommon and LV volumes and ejection fraction were similar. PMID:27504003

    2002-01-01

    Objective: To evaluate the efficacies of percutaneous coronary intervention (PCI) and drug treatment in patients with unstable angina (UAP). Methods: 248 patients with UAP were divided into two groups: conservative group of 123 patients who received antiplatelet, anticoagulant and antianginal therapies only and invasive group of 125 patients who underwent additional PCI 4.4 days after admission. The occurrence of death, AMI, recurrent angina, readmission were assessed during the first hospitalization year. Results: There was no difference in the incidence of composite endpoint of death or AMI between the two groups during the hospitalization (0.8 % vs 1.6 %, P > 0.05 ), but hospitalization duration was shorter in the invasive group than in the conservative group (10.3 ± 5.6 days vs 14.6 ± 10.7 days, P < 0.01 ). In duration of one year, the incidence of AMI (2.4% vs 8.9%, P<0.03), death (1.6% vs 6.5%, P<0.05), composite endpoint of death or AMI (4.0 % vs 13.0 % P < 0.02), recurrent angina pectoris (26.4 % vs 48.7, P <0.001), CABG (1.6% vs 10.5%, P<0.01) and readmission (24.8% vs 45.5%, P<0.01) were also lower in the invasive group than in the conservative group. Survival rate free of composite death or AMI for 1 year was higher in the invasive group than in the conservative group(96.0 % vs 86.9 %, P < 0.02). There was a definite benefit of the invasive treatment in reducing the risk of composite endpoint of death or AMI in patients with chest pain at rest, troponin T positive and three vessel diseases. Old age, three vessel diseases, LAD disease, lower LVEF, ST-segment depression, diabetes and hypertension were the independent factors associated with composite of death or AMI. Conclusions: In patients with UAP, PCI associated with routine antiplatelet, anticoagulant and antiischemic treatment significantly decreases the incidence of adverse cardiac events and improves the survival rate in one year. Such beneficial effects can be more obvious for high-risk patients

    Previous studies of contrast-induced acute kidney injury (CI-AKI) were mostly based on selective percutaneous coronary intervention (PCI) cases, and risk factors of CI-AKI after emergency PCI are unclear. The aim of this study was to explore the risk factors of CI-AKI in a Chinese population undergoing emergency PCI. A total of 1061 consecutive patients undergoing emergency PCI during January 2013 and June 2015 were enrolled and divided into CI-AKI and non-CI-AKI group. Univariable and multivariable analyses were used to identify the risk factors of CI-AKI in emergency PCI patients. CI-AKI was defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dl (44.2 μmol/L) above baseline within 3 days after exposure to contrast medium. The incidence of CI-AKI in patients undergoing emergency PCI was 22.7% (241/1061). Logistic multivariable analysis showed that body surface area (BSA) (odds ratio [OR] 0.213, 95% confidence interval [CI]: 0.075-0.607, P= 0.004), history of myocardial infarction (MI) (OR 1.642, 95% CI: 1.079-2.499, P= 0.021), left ventricular ejection fraction (LVEF) (OR 0.969, 95% CI: 0.944-0.994, P= 0.015), hemoglobin (Hb) (OR 0.988, 95% CI: 0.976-1.000, P= 0.045), estimated glomerular filtration rate (OR 1.027, 95% CI: 1.018-1.037, P < 0.001), left anterior descending (LAD) stented (OR 1.464, 95% CI: 1.000-2.145, P= 0.050), aspirin (OR 0.097, 95%CI: 0.009-0.987, P= 0.049), and diuretics use (OR 1.850, 95% CI: 1.233-2.777, P= 0.003) were independent predictors of CI-AKI in patients undergoing emergency PCI. History of MI, low BSA, LVEF and Hb level, LAD stented, and diuretics use are associated with increased risk of CI-AKI in patients undergoing emergency PCI.

    Percutaneous coronary intervention (PCI) is a well-established method for managing coronary diseases. However, the increasing use of PCI has led to an increased incidence of acute cerebrovascular accidents (CVA) related to PCI. In this study, we investigated the characteristics and risk factors of CVA after PCI in patients with known stroke history. Between January 1, 2005 and March 1, 2009, 621 patients with a history of stroke underwent a total of 665 PCI procedures and were included in this retrospective study. Demographic and clinical characteristics, previous medications, procedures, neurologic deficits, location of lesion and in-hospital clinical outcomes of patients who developed a CVA after the cardiac catheterization laboratory visit and before discharge were reviewed. Acute CVA was diagnosed in 53 (8.5%) patients during the operation or the perioperative period. Seventeen patients suffered from transient ischemic attack, thirty-four patients suffered from cerebral infarction and two patients suffered from cerebral hemorrhage. The risk factors for CVA after PCI in stroke patients were: admission with an acute coronary syndrome, use of an intra-aortic balloon pump, urgent or emergency procedures, diabetes mellitus, and poor left ventricular systolic function, arterial fibrillation, previous myocardial infarction, dyslipidemia, tobacco use, and no/irregular use of anti-platelet medications. The incidence of CVA during and after PCI in patients with history of stroke is much higher than that in patients without history of stroke. Patients with atrial fibrillation, previous myocardial infarction, diabetes mellitus, dyslipidemia, tobacco use, and no or irregular use of anti-platelet medications were at higher risk for recurrent stroke. This study showed a strong association between acute coronary syndromes and in-hospital stroke after PCI.

    Limited data exist regarding the long-term prognosis of percutaneous coronary intervention (PCI) in young adults. The aim of this study was to retrospectively assess the long-term clinical outcomes in young patients who underwent PCI. Between 1985 and 2011, 7649 consecutive patients underwent PCI, and data from 69 young adults (age ≤40 years) and 4255 old adults (age ≧65 years) were analyzed. A Cox proportional hazards regression analysis was used to determine the independent predictors of a composite endpoint that included all-cause death and acute coronary syndrome (ACS) during the follow-up period. The mean age of the 69 young patients was 36.1±4.9 years, and 96% of them were men. Approximately 30% were current smokers, and their body mass index (BMI) was 26.7±5.0kg/m(2). The prevalence of diabetes and hypertension was 33% and 48%, respectively. All patients had ≥1 conventional cardiovascular risk factor. At a median follow-up of 9.8 years, the overall death rate was 5.8%, and new-onset ACS occurred in 8.7%. Current smoking was an independent predictor of the composite endpoint (hazard ratio 4.46, confidence interval 1.08-19.1, p=0.04) for young adults. Current smoking and obesity (high BMI) are the important clinical characteristics in young Japanese coronary heart disease patients who undergo PCI. The long-term prognosis in young patients is acceptable, but current smoking is a significant independent predictor of death and the recurrence of ACS in young Japanese coronary heart disease patients who are obese.

    The long-term outcome of percutaneous coronary intervention (PCI) vs. coronary artery bypass graft (CABG), particularly for patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), remains controversial.Methods and Results:We retrospectively analyzed 2,827 patients (stable coronary artery disease [SCAD], n=1,601; NSTE-ACS, n=1,226) who underwent either PCI (n=1,732) or CABG (n=1,095). The 8-year composite of cardiac death and myocardial infarction (MI) was compared between PCI and CABG before and after propensity matching. For patients with NSTE-ACS, PCI was performed more frequently for those with higher Thrombolysis in Myocardial Infarction risk score and 3-vessel disease, and PCI led to significantly higher 8-year composite of cardiac death and MI than CABG (14.1% vs. 5.9%, hazard ratio [HR]=2.22, 95% confidence interval [CI]=1.37-3.58, P=0.001). There was a significant interaction between clinical presentation and revascularization strategy (P-interaction=0.001). However, after matching, the benefit of CABG vs. PCI was attenuated in patients with NSTE-ACS, whereas it was pronounced in those with SCAD. Interactions between clinical presentation and revascularization strategy were not observed (P-interaction=0.574). Although the determinants of PCI vs. CABG in real-world clinical practice differ according to the clinical presentation, a significant interaction between clinical presentation and revascularization strategy was not noted for long-term outcomes. The revascularization strategy for patients with NSTE-ACS can be based on the criteria applied to patients with SCAD.

    Full Text Available Objective To explore the clinical efficacy of intra-aortic balloon pump (IABP as an auxiliary treatment of percutaneous coronary intervention (PCI in patients with coronary heart disease (CHD associated with chronic kidney disease. Methods One hundred and twenty CHD patients with concomitant chronic kidney disease and receiving PCI in our hospital from Jan. 2000 to Jul. 2014, and 123 simple CHD patients without renal dysfunction, who had undergone PCI with concomitant IABP for the cardiac pump failure, cardiogenic shock, acute left heart failure, unstable angina pectoris (UP which was not allayed by medical treatment, or acute myocardial infarction (AMI, were selected for observation of preoperative condition, in-hospital mortality and prognosis of patients in two groups. Results There was no statistically significant difference in general clinical data including gender, age, and concomitant hypertension and diabetes, and preoperative blood lipid, AST, D-dimer, APTT, and international normalized ratio (INR showed also no statistically significant difference before surgery between two groups of patients (P>0.05. The difference in proportion of AMI, the left main trunk and (or three-branches involvement was of no statistical significance (P>0.05, but there was significant difference in the incidence of previous myocardial infarction, TnT, CK-MB, Cr, BUN, stent number, IABP application time (P0.05 between the two groups. Logistic regression analysis revealed that diabetes and the number of stents were independent risk factors for in-hospital and long-term mortalities. Conclusions By means of the effective cardiac assistance of IABP, CHD patients with renal insufficiency have the same short and long term clinical prognosis as simple CHD patients without renal dysfunction who has undergone PCI. Diabetes and the number of stents are independent risk factors for in-hospital and 1-year mortality. DOI: 10.11855/j.issn.0577-7402.2015.04.03

    Full Text Available Stroke is a rare but serious adverse event associated with percutaneous coronary intervention (PCI. However, the relative risk of stroke between stable patients undergoing a direct PCI strategy and those undergoing an initial optimal medical therapy (OMT strategy has not been established yet. This study sought to investigate if, in patients with stable coronary artery disease (SCAD, an initial strategy PCI is associated with a higher risk of stroke than a strategy based on OMT alone.We performed a meta-analysis of 6 contemporary randomized control trials in which 5673 patients with SCAD were randomized to initial PCI or OMT. Only trials with stent utilization more than 50% were included. Study endpoint was the rate of stroke during follow up.Mean age of patients ranged from 60 to 65 years and stent utilization ranged from 72% to 100%. Rate of stroke was 2.0% at a weighted mean follow up of 55.3 months. On pooled analysis, the risk of stroke was similar between patients undergoing a PCI plus OMT and those receiving only OMT (2.2% vs. 1.8%, OR on fixed effect = 1.24 95%CI: 0.85-1.79. There was no heterogeneity among the studies (I2 = 0.0%, P = 0.15. On sensitivity analysis after removing each individual study the pooled effect estimate remains unchanged.In patients with SCAD an initial strategy based on a direct PCI is not associated with an increased risk of stroke during long-term follow up compared to an initial strategy based on OMT alone.

    The purpose of this study was to examine the association between statin use by individuals and the risk for incident diabetes mellitus in patients with acute coronary syndrome (ACS) following percutaneous coronary intervention (PCI). We conducted a retrospective cohort study of patients who were hospitalized for ACS between January 1, 2006, and December 31, 2010, and who had undergone PCI (n=30,665); the data were retrieved from the Taiwan National Health Insurance Research Database. A propensity score technique was used to establish a 1:1 matched cohort for statin users and non-statin users (n=9043 for each group). The risk for incident diabetes mellitus in statin users compared to non-statin users for patients with ACS after PCI was estimated by the multivariable Cox proportional hazards regression model. Statin use was associated with a significant increase of 27% in the risk for new-onset diabetes mellitus (adjusted hazard ratio [HR] 1.27, 95% CI 1.14 to 1.41) compared to non-statin use in the matched cohort. The matched cohort analysis indicated that almost all individual statins were associated with a statistically significant increase in the risk for new-onset diabetes mellitus compared to those without statin use. Our study indicated an association between increased risk for new-onset diabetes mellitus and statin use. Because the benefits of statins in prevention of morbidity and mortality in patients with ACS are well-established, clinical decision making should not be changed for patients with existing cardiovascular disease in whom statin therapy is recommended.

    Myocardial revascularization by either coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI) carries the risk of serious complications. Observational data suggest that outcomes may be improved by experienced operators, but there are few studies that have analysed the relationship between mortality and primary operator grade. The aim of this study was to investigate the effect of operator grade (trainee vs. consultant) upon outcomes of revascularization procedures. This was an observational study at a tertiary cardiology centre with accredited training programmes, between 2003 and 2011. A total of 22 697 consecutive patients undergoing either CABG or PCI were included. Associations between operator grade and mortality were assessed by hazard ratios, estimated by Cox regression analyses; 6689 patients underwent CABG, whereas 16 008 underwent PCI. Trainees performed 1968 (29.4%) CABG procedures and 8502 (53.1%) PCI procedures. The proportion of procedures performed by trainees declined over time for both CABG (30.2% in 2003 vs. 26.0% in 2010) and for PCI (58.1% in 2003 vs. 44.5% in 2010). In the unadjusted Cox analysis, consultant operator grade was associated with an increased 5-year mortality after both CABG [HR: 1.26 (95% CI: 1.07-1.47)] and PCI procedures [HR: 1.34 (95% CI: 1.22-1.47)] compared with a trainee operator. However, following multiple adjustment, consultant grade was no longer associated with mortality after either procedure [CABG: HR: 1.02 (95% CI: 0.87-1.20), PCI: HR: 1.08 (95% CI: 0.98-1.20)]. There was no observed detrimental effect on patient outcomes arising from procedures undertaken by trainees working in a structured training environment compared with consultants.

    The purpose was to investigate if women with high pre-procedural anxiety reported higher degree of relaxation and comfort if listening to music during coronary angiographic procedures. A prospective randomized controlled trial was used included 68 patients undergoing coronary angiography and/or PCI. The women were allocated to receive calming music and standard care or standard care only. Relaxation, environmental sound and discomfort associated with lying still were assessed. There was significantly more positive impression of the sound environment and less discomfort associated with lying still in women listening to music in comparison to women who received only standard care. No effect in relaxation was found.

    The purpose of this study was to investigate the effects of aromatherapy on the anxiety, sleep, and blood pressure (BP) of percutaneous coronary intervention (PCI) patients in an intensive care unit (ICU). Fifty-six patients with PCI in ICU were evenly allocated to either the aromatherapy or conventional nursing care. Aromatherapy essential oils were blended with lavender, roman chamomile, and neroli with a 6 : 2 : 0.5 ratio. Participants received 10 times treatment before PCI, and the same essential oils were inhaled another 10 times after PCI. Outcome measures patients' state anxiety, sleeping quality, and BP. An aromatherapy group showed significantly low anxiety (t = 5.99, P aromatherapy effectively reduced the anxiety levels and increased the sleep quality of PCI patients admitted to the ICU. Aromatherapy may be used as an independent nursing intervention for reducing the anxiety levels and improving the sleep quality of PCI patients. PMID:23476690

    It was medical applications that stimulated F. Carrol in the early 1990s to start the research of on relativistic Thomson scattering X-ray sources, as a part of the infrastructure of the future society. The possibility to use such a source in interventional cardiology is discussed in this paper. The replacement of X-ray tube by relativistic Thomson scattering Xray source is predicted to lower the patient radiation dose by a factor of 3 while image quality remains the same. The required general characteristics of accelerator and laser units are found. They can be reached by existing technology. A semiempirical method for simulation of medical and technical parameters of interventional coronary angiography systems is suggested.

    Coronary artery disease has a significant disease burden, but there are many known barriers to management of acute coronary syndrome (ACS). General practitioners (GPs) bear considerable responsibility for post-discharge management of ACS in Australia and New Zealand (NZ), but knowledge about the extent and efficacy of such management is limited. This systematic review summarises published evidence from Australia and New Zealand regarding management in primary care after discharge following ACS. A search of PubMed, Scopus, CINAHL-Plus and PSYCINFO databases in August 2015 was supplemented by citation screening and hand-searching. Literature was selected based on specified criteria, and assessed for quality using the Mixed Methods Appraisal Tool (MMAT). Extracted data was related to evidence-based interventions specified by published guidelines. The search yielded 19 publications, most of which reported on quantitative and observational studies from Australia. The majority of studies scored at least 75 % on the MMAT. Diverse aspects of management by GPs are presented according to categories of evidence-based guidelines. Data suggests that GPs are more likely to prescribe ACS medications than to assist in lifestyle or psychological management. GP referral to cardiac rehabilitation varied, and one study showed an improvement in the number of ACS patients with documented ACS management plans. Few studies described successful interventions to improve GP management, though some quality improvement efforts through education and integration of care with hospitals were beneficial. Limited data was published about interventions effective in rural, minority, and Indigenous populations. Research reflects room for improvement in GP post-discharge ACS management, but little is known about effective methods for improvement. Additional research, both observational and interventional, would assist GPs in improving the quality of post-discharge ACS care.

    A staged approach of percutaneous coronary intervention (PCI) followed by minimally invasive valve surgery (MIVS) is an alternative to the conventional combined coronary artery bypass and valve surgery for patients with concomitant coronary artery and valve disease. Limited data exist on degree of the completeness of revascularization achieved with this approach and its impact on outcomes. A total of 138 patients, who underwent a staged approach between January 2009 and June 2013, were retrospectively evaluated. Coronary angiograms were reviewed by two cardiologists blinded to outcomes and were then categorized into two groups: complete or incomplete revascularization, which was defined as ≥1 major epicardial coronary arteries of at least 2.0 mm diameter with ≥70% untreated obstruction after the index PCI and before MIVS. Complete and incomplete revascularization was achieved in 105 (76%) and 33 (24%) patients, respectively. The patients with incomplete revascularization had a lower ejection fraction, a higher STS score, and more prior myocardial infarctions and multi-vessel coronary artery disease. There were no differences in the post-operative complications, 30-day mortality, or 3-year survival (84 vs. 83%, P = 0.68). After a median follow-up of 29 months, incompletely revascularized patients had a higher incidence of acute coronary syndrome (2.9 vs. 12.9%, P = 0.05). In patients undergoing a staged approach of PCI followed by MIVS, incomplete revascularization did not significantly impact the short or mid-term survival, but was associated with an increased incidence of acute coronary syndrome at follow-up. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    To study the possibilities of stress echocardiography (EchoCG) in the assessment of clinical state of patients after percutaneous coronary intervention (PCI). We included into this study 80 patients with stable ischemic heart disease. After preliminary examination, all patients underwent PCI. Stress EchoCG was carried out in 6 and 12 months after PCI. Clinical effect assessed in 12 months after revascularization was good in 90% of patients. We registered significant increase of exercise capacity (from 97 to 118 W; p=0.001), increase of double product (from 232 to 275; p=0.009), decrease of myocardial ischemia volume (regional contractility impairment index before PCI 1.36, a year after PCI 1.16; p=0.001). The incidence of restenosis was 7.5%. Restenosis was accompanied by a deterioration of clinical status of patients (silent myocardial ischemia, angina recurrence). The accuracy of stress echocardiography in detecting myocardial ischemia in patients after PCI was 94%. Stress EchoCG has high diagnostic accuracy for detection of myocardial ischemia in patients after PCI during the first 12 months after revascularization.

    Contrast-induced nephropathy (CIN) is an important complication following percutaneous coronary intervention (PCI). The clinical importance of a minimum contrast media volume (CMV) for PCI to prevent CIN has not been well evaluated. The purpose of this study was to evaluate the impact of minimum CMV to prevent CIN after PCI. In this study, 2052 consecutive patients who underwent elective PCI in our institute were analyzed. We divided patients into two groups according to CMV: a minimum CMV PCI group [CMV ≤50 ml (n = 94)] and a non-minimum CMV PCI group [CMV >50 ml (n = 1958)]. CIN occurred in 160 (7.8 %) patients. The incidence of CIN was significantly lower in the minimum CMV PCI group than in the non-minimum CMV PCI group (2.1 vs. 8.1 %; P = 0.03). According to multivariate analysis, elderly patients and diabetes mellitus patients were at high risk of developing CIN in this study population. When analyzing only high-risk patients, the incidence of CIN was also significantly lower in the minimum CMV group than in the non-minimum CMV group (2.6 vs. 10.3 %; P = 0.03). Minimum CMV PCI could reduce the incidence of CIN, particularly in high-risk patients; as such, defining the minimum CMV clinical cut-off values may be useful for the prevention of CIN.

    Full Text Available Abstract Background Administration of abciximab during primary percutaneous coronary intervention is an effective adjunctive therapy in the treatment of patients with ST-segment elevation myocardial infarction. Recent small-scaled studies have suggested that intracoronary administration of abciximab during primary percutaneous coronary intervention is superior to conventional intravenous administration. This study has been designed to investigate whether intracoronary bolus administration of abciximab is more effective than intravenous bolus administration in improving myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention with thrombus aspiration. Methods/Design The Comparison of IntraCoronary versus intravenous abciximab administration during Emergency Reperfusion Of ST-segment elevation myocardial infarction (CICERO trial is a single-center, prospective, randomized open-label trial with blinded evaluation of endpoints. A total of 530 patients with STEMI undergoing primary percutaneous coronary intervention are randomly assigned to either an intracoronary or intravenous bolus of weight-adjusted abciximab. The primary end point is the incidence of >70% ST-segment elevation resolution. Secondary end points consist of post-procedural residual ST-segment deviation, myocardial blush grade, distal embolization, enzymatic infarct size, in-hospital bleeding, and clinical outcome at 30 days and 1 year. Discussion The CICERO trial is the first clinical trial to date to verify the effect of intracoronary versus intravenous administration of abciximab on myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention with thrombus aspiration.

    Background: The EucaTax stent (EUPES) is a coronary stent with biodegradable polymer and camouflage coating that has been developed to promote the complete elution of drugs and decrease the risk of late complications. The aim of this study was to evaluate the efficacy and safety of the double-coated EUPES in patients with stable angina versus sirolimus-eluting stent CYPHER (SES) with permanent polymer coating. Methods and Materials: The study included consecutive patient with at least 70% de novo coronary lesions in one or two native coronary arteries and who had undergone the coronary stenting using either EUPES or SES. We evaluated the 2-year major adverse cardiac events (MACE) rates, including total death (cardiac, non-cardiac), myocardial infarction (MI), target lesion revascularisation (TLR) and stent thrombosis. Results: Between 2006 and 2009 this observational, prospective, single centre study included 602 patients (282 with EUPES and 320 with SES). At 2 years, the rates of TLR (16.3% versus 6.25%; p = 0.0001) and MACE (18.4% versus 7.8%; p = 0.001) were significantly higher in the EUPES than in the SES group. The rate of TLR was significantly higher in the EUPES group compared with SES group in stenting of artery with a diameter less than 3 mm, using stent length more than 18 mm, as well as when the residual stenosis was more than 12%. Conclusions: We found that EUPES was inferior to SES during the 2-year follow-up with respect to rates of MACE and TLR that were significantly higher in the EUPES than in the SES group.

    Early coronary intervention in patients with non-ST segment elevation acute coronary syndromes (ACS) may be facilitated by adjunctive pharmacotherapies. Concomitant therapies such as low-molecular-weight heparins and platelet glycoprotein (GP) IIb/IIIa receptor blockade offer advantages in safety and efficacy during coronary intervention. Data from randomized clinical trials support the administration of both enoxaparin and platelet GP IIb/IIIa blockade to patients who present with non-ST segment elevation ACS. Enoxaparin, with its proven efficacy, predictability of action, and ease of administration, has been shown to be superior to unfractionated heparin in preventing major coronary events. Abciximab administration during percutaneous coronary intervention (PCI) reduces the incidence of ischemic adverse outcomes and appears to improve survival in long-term follow-up. The preliminary experience with combining these two therapies during PCI in the NICE 4 trial demonstrates a low incidence of minor/major bleeding and transfusion, and infrequent major cardiac events to 30 days follow-up. Algorithms for the use of these newer adjunctive pharmacotherapies in the care of patients presenting to the cardiac catheterization laboratory are presented.
