    Coronary perforation (CP) is a life-threatening complication that can occur during percutaneous coronary intervention (PCI). Little is known, however, about the incidence and clinical outcome of CP. We sought to investigate the occurrence of CP and its determinants and risk profile in a large-scale, prospective registry. From 2005 to 2008, unselected patients (n = 42,068) from 175 centers in 33 countries who underwent a PCI procedure were prospectively enrolled in the PCI registry of the Euro Heart Survey program. For the present analysis, patients experiencing CP during PCI (n = 124, 0.3%) were compared with those who underwent PCI without CP. Patients with CP were older, more often women, had more severe coronary disease, and underwent more complex types of coronary intervention. Independent factors associated with CP were the use of rotablation, intravascular ultrasound-guided PCI, bypass PCI, a totally occluded vessel, a type C lesion, peripheral arterial disease, and body mass index <25. More than 10% of the patients developed cardiac tamponade. In a small minority (3.3%), emergency bypass surgery had to be performed. The inhospital death rate was markedly elevated in patients with CP (7.3% vs 1.5%, p <0.001). After adjustment for the EuroHeart score, CP remained a strong predictor of hospital mortality (odds ratio 5.21, 95% confidence interval 2.34 to 11.60). In conclusion, in this real world, all-comers registry, the incidence of CP was low, occurred more often in patients who underwent more complex coronary interventions, and was associated with a fivefold higher hospital mortality.

    The aim of the present paper is to report trends in Portuguese interventional cardiology from 2004 to 2013 and to compare them with other European countries. Based on the Portuguese National Registry of Interventional Cardiology and on official data from the Directorate-General of Health, we give an overview of developments in coronary interventions from 2004 to 2013. In 2013, 36 810 diagnostic catheterization procedures were performed, representing an increase of 34% compared to 2007 and a rate of 3529 coronary angiograms per million population. Coronary interventions increased by 65% in the decade from 2004 to 2013, with a total of 13 897 procedures and a rate of 1333 coronary interventions per million population in 2013. Primary percutaneous coronary intervention (PCI) increased by 265% from 2004 to 2013 (1328 vs. 3524), an adjusted rate of 338 primary PCIs per million, representing 25% of total angioplasties. Stents were the most frequently used devices, drug-eluting stents being used in 73% in 2013. Radial access increased from 4.1% in 2004 to 57.9% in 2013. Interventional cardiology in Portugal has been expanding since 2004. We would emphasize the fact that in 2013 all Portuguese interventional cardiology centers were participating in the National Registry of Interventional Cardiology, as well as the growth in primary PCI and increased use of radial access.

    The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the data from the registry of the activity in Spain in 2014. Data were voluntarily provided by participating centers. The information was introduced online and was analyzed by the Steering Committee of the Working Group on Cardiac Catheterization and Interventional Cardiology. Data were reported by 106 hospitals. A total of 140 461 diagnostic procedures (125 484 coronary angiograms) were performed, representing a rate of 3014 diagnostic studies per million population. This year, the number of percutaneous coronary interventions increased to 67 611, giving a rate of 1447 interventions per million population. A total of 94 458 stents were implanted, including 64 057 drug-eluting stents and 2424 biodegradable intracoronary devices. Of the total number of percutaneous coronary interventions, 17 825 were in acute myocardial infarction, representing 26.4% of all coronary interventions. A radial approach was used in 74% of diagnostic procedures and in 70.4% of interventional procedures. The use of renal denervation decreased, whereas over 125 mitral leak closures were performed. Transcatheter aortic valve implantation procedures exceeded 1300 implantations per year, a 27% increase from 2013. The registry for 2014 shows a slight increase in coronary disease activity despite no increase in the management of ST-segment elevation myocardial infarction. Drug-eluting intracoronary devices now comprise over 70% of all intracoronary devices. A continual increase is only seen in certain structural interventional techniques, such as transcatheter aortic valve implantation and perivalvular leak closure.

    Our aim was to investigate in-hospital outcomes of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) using contemporary techniques. Despite its increasing popularity and technical complexity, clinical outcomes of PCI for CTO using contemporary techniques have not been adequately evaluated. The J-CTO registry (multicenter CTO registry in Japan) is a large scale, multicenter registry enrolling consecutive patients undergoing PCI for CTO from 12 Japanese centers. In-hospital clinical outcomes were evaluated in 498 patients with 528 CTO lesions. Multiple wiring strategies were frequently attempted (parallel wiring 31% and retrograde approach 25%) with relatively long guidewire manipulation time (median 30 min). Utilizing these complex strategies, high procedural success rates (88.6% in the first attempt cases and 68.5% in the retry cases) were accomplished. In-hospital adverse event rates were strikingly low (cardiac death 0.2%, Q-wave myocardial infarction 0.2%, and stroke 0%). Potential disadvantages of these procedures, including a large amount of contrast volume (median 293 ml) and long fluoroscopic time (median 45 min), were not associated with serious clinical sequelae (contrast induced nephropathy 1.2% and radiation dermatitis 0%). Although coronary perforations were documented frequently by angiography (antegrade 7.2% and retrograde 13.6%), clinically significant perforation resulting in cardiac tamponade was rare (0.4%). Most CTO lesions can be safely and successfully treated with PCI utilizing contemporary advanced techniques. Invasiveness and potential risks of these strategies, which have been the greatest concerns of CTO treatment, may be acceptable in the majority of cases considering the actual incidences of related adverse events and the procedural success rates.

    The Working Group on Cardiac Catheterization and Interventional Cardiology presents the yearly report on the data collected for the Spanish registry. Institutions provided their data voluntarily (online) and the information was analyzed by the Working Group's Steering Committee. Data were provided by 109 hospitals (71 public and 38 private) that mainly treat adults. There were 136,912 diagnostic procedures, 120, 441 of which were coronary angiograms, slightly fewer than the year before, with a rate of 2979 diagnostic studies per million population. Percutaneous coronary interventions increased slightly to 65,909 procedures, for a rate of 1434 interventions per million population. Of the 99,110 stents implanted, 62% were drug-eluting stents. In all, 17,125 coronary interventions were carried out during the acute phase of myocardial infarction, 10.5% more than in 2011, representing 25.9% of the total number of coronary interventions. The most frequently performed intervention for adult congenital heart disease was atrial septal defect closure (292 procedures). The use of percutaneous mitral valvuloplasty continued to decline (258 procedures) and percutaneous aortic valve implantations increased by only 10% in 2012. In 2012, the only increase in hemodynamic activity occurred in the field of ST-elevation myocardial infarction, and the increasing trend had slowed for percutaneous aortic valve implantation and other procedures affecting structure.

    Background The recommendations in guidelines are based on evidence; however, there is a gap between recommendations and clinical practice. Objective To describe the practice of prescribing evidence-based treatments for patients with acute coronary syndrome in Brazil. Methods This study carried out a subanalysis of the ACCEPT registry, assessing epidemiological data and the prescription rate of acetylsalicylic acid, p2y12 inhibitors, antithrombotic drugs, beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (IAT1RB), and statins. In addition, the quality of myocardial reperfusion in ST-segment elevation myocardial infarction was evaluated. Results This study assessed 2,453 patients. The prescription rates of acetylsalicylic acid, p2y12 inhibitors, antithrombotic drugs, beta-blockers, angiotensin-converting enzyme inhibitors/IAT1RB, and statins were as follows: in 24 hours - 97.6%, 89.5%, 89.1%, 80.2%, 67.9% and 90.6%; and at six months - 89.3%, 53.6%, 0%, 74.4%, 57.6% and 85.4%, respectively. Regarding ST-segment elevation myocardial infarction, only 35.9% and 25.3% of the patients underwent primary angioplasty and thrombolysis, respectively, within the recommended times. Conclusion This registry showed high initial prescription rates of antiplatelet drugs, antithrombotic drugs, and statins, and lower prescription rates of beta-blockers and angiotensin-converting enzyme inhibitors/IAT1RB. Independently of the class, the use of all drugs decreased by six months. Most patients with ST-segment elevation myocardial infarction did not undergo myocardial reperfusion within the time recommended. PMID:24652052

    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.

    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.

    2011-01-01

    BACKGROUND: An increasing proportion of patients with acute coronary syndrome (ACS) requiring percutaneous coronary intervention (PCI) are classified as elderly (aged =70 years). The glycoprotein IIb/IIIa inhibitor abciximab is known to reduce adverse outcomes in patients aged high......-risk ACS undergoing PCI, but conflicting findings relating to its effects in the elderly have been reported. OBJECTIVE: The aim of this study was to evaluate the effect of abciximab in elderly high-risk ACS patients undergoing PCI. METHODS: From our dedicated PCI registry we identified 2068 ACS patients...... with high-risk lesions that were treated with PCI. Baseline data were collected prospectively. All-cause mortality, target vessel revascularization (TVR), myocardial infarction (MI), and the combination of these were primary study endpoints. All endpoints within 1 year after PCI were registered...

    The aim of this study was to evaluate clinical characteristics, procedural details, and outcomes of patients undergoing elective multivessel percutaneous coronary intervention (MV-PCI) in Europe. A total of 7113 patients with stable coronary artery disease and at least two major epicardial vessels with ≥ 70% stenosis were included in this analysis of the contemporary Euro Heart Survey PCI registry. Patients undergoing MV-PCI (n = 3376, 47.5%) were compared with those with single-vessel PCI (SV-PCI) (n = 3737, 52.5%). Patients with MV-PCI were more likely to have congestive heart failure, whereas those with SV-PCI more often suffered from noncardiac comorbidities. Hospital mortality (0.1% vs 0.3%) and the incidence of nonfatal postprocedural myocardial infarction (1.0% vs 0.7%) were low in patients with MV-PCI and SV-PCI. In the multivariate analysis, no significant difference in the incidence of hospital death (odds ratio (OR) 0.44, 95% confidence interval (CI) 0.15-1.27) could be observed between the two groups. However, the risk for postprocedural myocardial infarction (OR 1.57, 95% CI 0.93-2.67) tended to be higher among patients undergoing MV-PCI. Independent determinants for performing MV-PCI were age, comorbidities, and coronary anatomy. In Europe almost half of all patients with multivessel disease were treated with MV-PCI. Hospital complications were low, but a trend toward a higher rate of postprocedural myocardial infarctions was seen in patients with MV-PCI.

    Despite improving success rate of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions, the clinical benefit of recanalization of CTO is still a matter of debate. Of 13,087 patients who underwent PCI in the CREDO-Kyoto registry cohort-2, 1,524 patients received PCI for CTO (CTO-PCI). Clinical outcomes were compared between 1,192 patients with successful CTO-PCI and 332 patients with failed CTO-PCI. In-hospital death tended to occur less frequently in the successful CTO-PCI group than in the failed CTO-PCI group (1.4% vs 3.0%, p = 0.053). Through 3-year follow-up, the cumulative incidence of all-cause death was not significantly different between the successful and failed CTO-PCI groups (9.0% vs 13.1%, p = 0.18), whereas the cumulative incidence of cardiac death was significantly less in the successful CTO-PCI group than in the failed CTO-PCI group (4.5% vs 8.4%, p = 0.03). However, after adjusting confounders, successful CTO-PCI was associated with lesser risk for neither all-cause death (hazard ratio 0.93, 95% confidence interval 0.64 to 1.37, p = 0.69) nor cardiac death (hazard ratio 0.71, 95% confidence interval 0.44 to 1.16, p = 0.16). The cumulative incidence of coronary artery bypass grafting (CABG) was remarkably less in patients with successful PCI compared with those with failed PCI (1.8% vs 19.6%, p <0.0001). In conclusion, successful CTO-PCI compared with failed PCI was not associated with lesser risk for 3-year mortality. However, successful CTO-PCI was associated with significantly less subsequent CABG.

    The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the data from the registry of the activity in 2015. All Spanish hospitals with catheterization laboratories were invited to voluntarily contribute their activity data. The information was collected online and analyzed mostly by an independent company. In 2015, 106 centers participated in the national register; 73 of these centers are public. A total of 145 836 diagnostic studies were conducted, among which 128 669 were coronary angiograms. These figures are higher than in previous years. The Spanish average of total diagnoses per million population was 3127. The number of coronary interventional procedures was very similar (67 671), although there was a slight increase in the complexity of coronary interventions: 7% in multivessel treatment and 8% in unprotected left main trunk treatment. A total of 98 043 stents were implanted, of which 74 684 were drug-eluting stents. A total of 18 418 interventional procedures were performed in the acute myocardial infarction setting, of which 81.9% were primary angioplasties. The radial approach was used in 73.3% of the diagnostic procedures and in 76.1% of interventional ones. The number of transcatheter aortic valve implantations continued to increase (1586), as well as the number of left atrial appendage closures (331). An increase in diagnostic and therapeutic procedures in acute myocardial infarction was reported in 2015. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The progressive increase in structural procedures seen in previous years continued.

    The Working Group on Cardiac Catheterization and Interventional Cardiology presents its yearly report on the data from the registry of the activity in Spain corresponding to 2013. The centers introduce their data online voluntarily and the information is analyzed by the Steering Committee of the Working Group on Cardiac Catheterization. In 2013, 104 hospitals sent their data (72 public centers and 32 private). In all, 136 715 diagnostic studies were performed (120 358 coronary angiograms), with a slight decrease with respect to 2012, a reduction that was also observed in the rate, which was 2944 diagnostic studies per million population. A total of 65 912 interventional procedures were carried out during a phase of stability, for a rate of 1419 interventions per million population. Other techniques included the implantation of 99 417 stents and 1384 biodegradable intracoronary devices (64% of them drug-eluting devices). There were 18 337 procedures in acute myocardial infarction, for an increase of 7% with respect to 2012 and representing 27.8% of all the percutaneous coronary interventions. Radial access was the approach used in 71% of the diagnostic procedures and in 65% of the interventional procedures. The performance of renal denervation has nearly doubled with respect to 2012. For the first time, more than 1000 transcatheter aortic valve implantation procedures were carried out in 1 year, although the frequency increased only slightly (23%). There continued to be a slight increase in the activity in cardiac catheterization in association with ST-segment elevation myocardial infarction, whereas, with the exception of recently introduced, highly specific procedures, the use of the remainder of the procedures, among them transcatheter aortic valve implantation, leveled off.

    Full Text Available Abstract Background Psoriasis is an inflammatory disease associated with increased risk of coronary artery disease. However, the potential impact of psoriasis on the prognosis following percutaneous coronary revascularization (PCI is unknown. Methods The study comprised the entire Danish population undergoing first-time PCI in the period 2002–09. Cox regression models, controlling for age, gender, socioeconomic status, pharmacological treatment, and comorbidity were used to assess the risk of 1 all-cause mortality and 2 a composite endpoint of death, myocardial infarction, and stroke. Results A total of 53,141 patients with first-time PCI in the study period were identified. Of these, 1074 had mild psoriasis and 315 had severe psoriasis. Patients with severe psoriasis, but not those with mild disease had increased risk of both endpoints compared to patients without psoriasis. The incidence rates for all-cause mortality were 30.5 (CI 29.7-31.3, 29.9 (CI 24.7-36.1, and 47.2 (CI 35.0-63.6 per 1000 patient years for patients without psoriasis, with mild psoriasis, and with severe psoriasis, respectively. Hazard ratios were 1.10 (CI 0.91-1.33 and 1.67 (CI 1.24-2.26 for mild and severe psoriasis, respectively. Patients with severe psoriasis were less likely to receive secondary prevention pharmacotherapy with betablockers, statins and platelet inhibitors. Conclusion This first study of the prognosis following PCI in patients with psoriasis demonstrated an increased risk of all-cause mortality and of a composite of death, myocardial infarction and stroke, respectively, in patients with severe psoriasis compared to patients without psoriasis. Further studies of this novel association are needed.

    We developed a model that predicts difficulty of percutaneous coronary intervention for coronary chronic total occlusion (CTO) using coronary computed tomographic angiography. A total of 684 CTO lesions with preprocedural computed tomographic angiography were enrolled from 4 centers. Data were randomly divided into derivation and validation datasets at 2:1 ratio. The end point was successful guidewire crossing ≤30 minutes, which was met in 50%. The KCCT (Korean Multicenter CTO CT Registry) score was developed based on independent predictors identified by multivariable analysis, which were proximal blunt entry, proximal side branch, bending, occlusion length ≥15 mm, severe calcification, whole luminal calcification, reattempt, and ≥12 months or unknown duration of occlusion. The KCCT score was compared with the other prediction scores, including angiography-based J-CTO, PROGRESS-CTO, CL-score, and CT-based CT-RECTOR. The probability of guidewire crossing ≤30 minutes declined consistently from 100% to 0% according to the KCCT score (PCTO percutaneous coronary intervention. © 2017 American Heart Association, Inc.

    The long-term outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) for unprotected left main coronary artery disease (ULMCAD) remains to be investigated. We identified 1,005 patients with ULMCAD of 15,939 patients with first coronary revascularization enrolled in the CREDO-Kyoto PCI/CABG Registry Cohort-2. Cumulative 3-year incidence of a composite of death/myocardial infarction (MI)/stroke was significantly higher in the PCI group than in the CABG group (22.7% vs 14.8%, p = 0.0006, log-rank test). However, the adjusted outcome was not different between the PCI and CABG groups (hazard ratio [HR] 1.30, 95% confidence interval [CI] 0.79 to 2.15, p = 0.30). Stratified analysis using the SYNTAX score demonstrated that risk for a composite of death/MI/stroke was not different between the 2 treatment groups in patients with low (<23) and intermediate (23 to 33) SYNTAX scores (adjusted HR 1.70, 95% CI 0.77 to 3.76, p = 0.19; adjusted HR 0.86, 95% CI 0.37 to 1.99, p = 0.72, respectively), whereas in patients with a high SYNTAX score (≥33), it was significantly higher after PCI than after CABG (adjusted HR 2.61, 95% CI 1.32 to 5.16, p = 0.006). In conclusion, risk of PCI for serious adverse events seemed to be comparable to that after CABG in patients with ULMCAD with a low or intermediate SYNTAX score, whereas PCI compared with CABG was associated with a higher risk for serious adverse events in patients with a high SYNTAX score.

    BACKGROUND: Elderly patients with ST-segment elevation myocardial infarction (STEMI) constitute a particular risk group in relation to primary percutaneous coronary intervention (PPCI). OBJECTIVE: We examined the proportion of octogenarians and nonagenarians undergoing PPCI in Western Denmark......, and their short- and long-term mortality rates. METHODS: From 2002 to 2009 all consecutive patients ≥80 years with STEMI treated with PPCI were identified in the population based Western Denmark Heart Registry. Cox regression analysis was used to compute hazard ratios, controlling for potential confounding....... RESULTS: A total of 1,322 elderly (1,213 octogenarians and 109 nonagenarians), corresponding to 11.6% of the total PPCI treated STEMI population, were treated with PPCI between 2002 and 2009. The annual proportion of octogenarians referred for PPCI increased from n=52 (6.2%) in 2002 to n=172 (11...

  5. Combined Value of Red Blood Cell Distribution Width and Global Registry of Acute Coronary Events Risk Score for Predicting Cardiovascular Events in Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention.

    Full Text Available 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 < 0.001; 1.699; 1.294-2.232; p < 0.001; respectively. Furthermore, Kaplan-Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001. For GRACE score alone, the area under the receiver operating characteristic (ROC curve for MACEs was 0.749 (95% CI: 0.707-0.787. The area under the ROC curve for MACEs increased to 0.805 (0.766-0.839, p = 0.034 after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001 and integrated discrimination improvement (IDI = 0.023, p = 0.002. Combining the predictive 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. Results were encouraging with a low composite rate of cardiac death

    Background The performance of the J-CTO score in predicting success and efficiency of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. Methods and Results We examined the records of 650 consecutive patients who underwent CTO PCI between 2011 and 2014 at six experienced centers in the United States. Six hundred and fifty-seven lesions were classified as easy (J-CTO=0), intermediate (J-CTO=1), difficult (J-CTO=2), and very difficult (J-CTO≥3). The impact of the J-CTO score on technical success and procedure time was evaluated with univariable logistic and linear regression, respectively. The performance of the logistic regression model was assessed with the Hosmer-Lemeshow statistic and receiver operator characteristic curves. Antegrade wiring techniques were used more frequently in easy lesions (97%) than very difficult lesions (58%), whereas the retrograde approach became less frequent with increased lesion difficulty (41% for very difficult lesions vs. 13% for easy lesions). The logistic regression model for technical success demonstrated satisfactory calibration and discrimination (p for Hosmer-Lemeshow=0.743 and area under curve=0.705). The J-CTO score was associated with a two-fold increase in the odds of technical failure (odds ratio 2.04, 95% confidence interval [95% CI] 1.52-2.80, pCTO score (regression coefficient 22.33, 95% CI 17.45-27.22, pCTO score was strongly associated with final success and efficiency in this study, supporting its expanded use in CTO interventions.

    The randomized Stent Restenosis Study (STRESS) and Belgium Netherlands Stent (Benestent) trials established that elective use of Palmaz-Schatz stents (PSSs) in native coronary arteries with de novo lesions is associated with increased procedural success and reduced restenosis. However there are other clinical indications for which stents are commonly used (unplanned use, vein grafts, restenosis lesions) that are not addressed in these studies. From 1990-1992, 688 lesions in 628 patients were treated with PSSs in the New Approaches to Coronary Intervention (NACI) registry. Angiographic core laboratory readings were available for 543 patients (595 lesions, of which 106 were stented for unplanned indications, 239 were in saphenous vein bypass grafts, and 296 were previously treated). The cohort of patients in whom stents were placed for unplanned indications had more women, current smokers, and had a higher incidence of recent myocardial infarction (MI). Patients who underwent stenting of saphenous vein grafts were older, had a higher incidence of diabetes mellitus, unstable angina, prior MI, and congestive heart failure. Lesion success was similar in all cohorts (98%), but procedural success was significantly higher for planned stenting (96% vs 87%; p < 0.01). Predictors of adverse events in-hospital were presence of a significant left main stenosis and stenting for unplanned indication. The incidence of target lesion revascularization by 30 days was significantly higher for patients undergoing unplanned stenting due to a higher risk for stent thrombosis. Recent MI, stenting in native lesion, and small postprocedural minimum lumen diameter independently predicted target lesion revascularization at 30 days. Independent predictors of death, Q-wave myocardial infarction, or target lesion revascularization at 1 year included severe concomitant disease, high risk for surgery, left main disease, stenting in the left main coronary artery, and low postprocedure minimum lumen

    The Synergy Between PCI With TAXUS and Cardiac Surgery (SYNTAX) score is effective in predicting clinical outcome after percutaneous coronary intervention (PCI). However, its prediction ability is low because it reflects only the coronary characterization. We assessed the predictive value of combining the ankle-brachial index (ABI) and SYNTAX score to predict clinical outcomes after PCI. The ABI-SYNTAX score was calculated for 1,197 patients recruited from the Shinshu Prospective Multi-center Analysis for Elderly Patients with Coronary Artery Disease Undergoing Percutaneous Coronary Intervention (SHINANO) registry, a prospective, observational, multicenter cohort study in Japan. The primary end points were major adverse cardiovascular and cerebrovascular events (MACE; all-cause death, myocardial infarction, and stroke) in the first year after PCI. The ABI-SYNTAX score was calculated by categorizing and summing up the ABI and SYNTAX scores. ABI ≤ 0.49 was defined as 4, 0.5 to 0.69 as 3, 0.7 to 0.89 as 2, 0.9 to 1.09 as 1, and 1.1 to 1.5 as 0; an SYNTAX score ≤ 22 was defined as 0, 23 to 32 as 1, and ≥ 33 as 2. Patients were divided into low (0), moderate (1 to 2), and high (3 to 6) groups. The MACE rate was significantly higher in the high ABI-SYNTAX score group than in the lower 2 groups (low: 4.6% vs moderate: 7.0% vs high: 13.9%, p = 0.002). Multivariate regression analysis found that ABI-SYNTAX score independently predicted MACE (hazards ratio 1.25, 95% confidence interval 1.02 to 1.52, p = 0.029). The respective C-statistic for the ABI-SYNTAX and SYNTAX score for 1-year MACE was 0.60 and 0.55, respectively. In conclusion, combining the ABI and SYNTAX scores improved the prediction of 1-year adverse ischemic events compared with the SYNTAX score alone.

    Chronic total occlusion (CTO) in a non-infarct-related artery (IRA) is an independent predictor of clinical outcomes in patients with acute myocardial infarction (AMI). This study evaluated the impact of successful percutaneous coronary intervention (PCI) for CTO of a non-IRA on the long-term clinical outcomes in patients with AMI. A total of 4,748 patients with AMI were consecutively enrolled in the Convergent Registry of Catholic and Chonnam University for AMI registry from January 2004 to December 2009. We enrolled 324 patients with CTO in a non-IRA. To adjust for baseline differences, propensity matching (96 matched pairs) was used to compare successful PCI and occluded CTO for the treatment of CTO in non-IRA. The primary clinical end points were all-cause mortality and a composite of the major adverse cardiac events, including cardiac death, MI, stroke, and any revascularization during the 5-year follow-up. Patients who received successful PCI for CTO of non-IRA had lower rates of all-cause mortality (16.7% vs 32.3%, hazard ratio 0.459, 95% CI 0.251 to 0.841, p = 0.012) and major adverse cardiac events (21.9% vs 55.2%, hazard ratio 0.311, 95% CI 0.187 to 0.516, p <0.001) compared with occluded CTO group. Subgroup analyses revealed that successful PCI resulted in a better mortality rate in patients with normal renal function compared to patients with chronic kidney disease (p = 0.010). In conclusion, successful PCI for CTO of non-IRA is associated with improved long-term clinical outcomes in patients with AMI.

    Information about the impact of race/ethnicity on adverse outcomes after percutaneous coronary intervention (PCI) in the modern era is limited. Using consecutive patients from the National Heart, Lung, and Blood Institute Dynamic Registry, this study investigated differences in clinical presentation, treatment strategy, and acute and long-term outcomes in 3,669 white, 446 black, 301 Hispanic, and 201 Asian patients who underwent PCI. All comparisons were made to whites. Blacks were more likely than whites to be younger, women, and to present with a higher prevalence of cardiovascular risk factors (hypertension, diabetes, and smoking). Hispanics tended to be younger, hypertensive, diabetic, and to be undergoing their first cardiovascular procedure. Asians were, on average, younger, men, and presented more often with hypertension and diabetes than whites. Although the rate of stent implantation was significantly lower in blacks compared with whites (63% vs 74%, p or =95%) and did not differ by race/ethnicity. In-hospital mortality (0.2% vs 1.7%, p presentation, angiographic characteristics and treatment strategies did not impact the incidence of acute and 1-year adverse outcomes of non-whites, there appears to be a significant reduction in event-free survival among blacks by 2 years.

    Ischemic heart disease is a major risk factor for morbidity and mortality in patients with end-stage renal disease. However, long-term benefits of percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG) in those patients is still unclear in the drug-eluting stent era. We identified 388 patients with multivessel and/or left main disease with end-stage renal disease requiring dialysis among 15,939 patients undergoing first coronary revascularization enrolled in the Coronary REvascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2 (PCI: 258 patients and CABG: 130 patients). The CABG group included more patients with 3-vessel (38% vs 57%, p <0.001) and left main disease (10% vs 34%, p <0.001). Preprocedural Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score in the CABG group was significantly higher than that in the PCI group (23.5 ± 8.7 vs 29.4 ± 11.0, p <0.001). Unadjusted 30-day mortality was 2.7% for PCI and 5.4% for CABG. Cumulative 5-year all-cause mortality was 52.3% for PCI and 49.9% for CABG. Propensity score-adjusted all-cause mortality was not different between PCI and CABG (hazard ratio [HR] 1.33, 95% confidence interval [CI] 0.85 to 2.09, p = 0.219). However, the excess risk of PCI relative to CABG for cardiac death was significant (HR 2.10, 95% CI 1.11 to 3.96, p = 0.02). The risk of sudden death was also higher after PCI (HR 4.83, 95% CI 1.01 to 23.08, p = 0.049). The risk of myocardial infarction after PCI tended to be higher than after CABG (HR 3.30, 95% CI 0.72 to 15.09, p = 0.12). The risk of any coronary revascularization after PCI was markedly higher after CABG (HR 3.78, 95% CI 1.91 to 7.50, p <0.001). Among the 201 patients who died during the follow-up, 94 patients (47%) died from noncardiac morbidities such as stroke, respiratory failure, and renal failure. In patients with multivessel and/or left main disease undergoing dialysis, 5-year

    In a large cohort of out-of-hospital cardiac arrest (OHCA) patients without ST-segment elevation (STE), the study assessed the relationship between the use of an early invasive strategy and patient outcome. Emergent coronary angiogram (CAG) and reperfusion are currently a standard of care in patients resuscitated from an OHCA with ST-segment elevation (STE). However, using a similar invasive strategy is still debated in patients without STE. In the absence of an obvious extracardiac cause, for many years our practice has had to perform an emergent CAG in all OHCA patients (STE and no STE) at admission, followed by percutaneous coronary intervention (PCI) when required. All patients' characteristics are prospectively collected in the PROCAT (Parisian Registry Out-of-Hospital Cardiac Arrest) database. Focusing on non-STE patients and using logistical regression, we investigated the association between early PCI and favorable outcome (cerebral performance category 1 to 2 at discharge) and we searched predictive factors for PCI requirement. During the study period (2004 to 2013), we investigated 958 OHCA patients with an emergent CAG. Among them 695 of 958 (73%), mostly male (76%), and average 60 years of age had no evidence of STE on the post-resuscitation electrocardiography. A PCI was deemed necessary in 199 of 695 (29%). A favorable outcome was observed in 87 of 200 (43%) in patients with PCI compared with 164 of 495 (33%) in patients without PCI (p = 0.02). After adjustment, PCI was associated with a better outcome (adjusted odds ratio: 1.80 [95% confidence interval: 1.09 to 2.97]; p = 0.02). The other predictive factors of favorable outcome were a shorter resuscitation length (coronary lesion requiring PCI was found in nearly one-third of OHCA patients without STE. In these patients, emergent PCI was associated with a nearly 2-fold increase in the rate of favorable outcome. These findings support the use of an invasive strategy in these patients, particularly

    The risk of acute kidney injury (AKI) is a major issue after percutaneous coronary interventions (PCIs), especially in the setting of ST-elevation myocardial infarction. Preliminary data from large retrospective registries seem to show a reduction of AKI when a transradial (TR) approach for PCI is adopted. Little is known about the relation between vascular access and AKI after emergent PCI. We here report the results of the Primary PCI from Tevere to Navigli (PRIPITENA), a retrospective database of primary PCI performed at high-volume centers in the urban areas of Rome and Milan. Primary end point of this study was the occurrence of AKI in the TR and transfemoral (TF) access site groups. Secondary end points were major adverse cardiovascular events, stent thrombosis, and Thrombolysis in Myocardial Infarction major and minor bleedings. The database included 1,330 patients, 836 treated with a TR and 494 with a TF approach. After a propensity-matched analysis performed to exclude possible confounders, we identified 450 matched patients (225 TR and 225 TF). The incidence of AKI in the 2 matched groups was lower in patients treated with TR primary PCI (8.4% vs 16.9%, p = 0.007). Major adverse cardiovascular events and stent thrombosis were not different among study groups, whereas major bleedings were more often seen in the TF group. At multivariate analysis, femoral access was an independent predictor of AKI (odds ratio 1.654, 95% confidence interval 1.084 to 2.524, p = 0.042). In conclusion, in this database of primary PCI, the risk of AKI was lower with a TR approach, and the TF approach was an independent predictor for the occurrence of this complication.

    Full Text Available Obesity is associated with advanced cardiovascular disease. However, some studies have reported the "obesity paradox" after percutaneous coronary intervention (PCI. The relationship between body mass index (BMI and clinical outcomes after PCI has not been thoroughly investigated, especially in Asian populations.We studied 10,142 patients who underwent PCI at 15 Japanese hospitals participating in the JCD-KICS registry from September 2008 to April 2013. Patients were divided into four groups according to BMI: underweight, BMI <18.5 (n=462; normal, BMI ≥ 18.5 and <25.0 (n=5,945; overweight, BMI ≥ 25.0 and <30.0 (n=3,100; and obese, BMI ≥ 30.0 (n=635.Patients with a high BMI were significantly younger (p<0.001 and had a higher incidence of coronary risk factors such as hypertension (p<0.001, hyperlipidemia (p<0.001, diabetes mellitus (p<0.001, and current smoking (p<0.001, than those with a low BMI. Importantly, patients in the underweight group had the worst in-hospital outcomes, including overall complications (underweight, normal, overweight, and obese groups: 20.4%, 11.5%, 8.4%, and 10.2%, p<0.001, in-hospital mortality (5.8%, 2.1%, 1.2%, and 2.7%, p<0.001, cardiogenic shock (3.5%, 2.0%, 1.5%, and 1.6%, p=0.018, bleeding complications (10.0%, 4.5%, 2.6%, and 2.8%, p<0.001, and receiving blood transfusion (7.6%, 2.7%, 1.6%, and 1.7%, p<0.001. BMI was inversely associated with bleeding complications after adjustment by multivariate logistic regression analysis (odds ratio, 0.95; 95% confidence interval, 0.92-0.98; p=0.002. In subgroup multivariate analysis of patients without cardiogenic shock, BMI was inversely associated with overall complications (OR, 0.98; 95% CI, 0.95-0.99; p=0.033 and bleeding complications (OR, 0.95; 95% CI, 0.91-0.98; p=0.006. Furthermore, there was a trend that BMI was moderately associated with in-hospital mortality (OR, 0.94; 95% CI, 0.88-1.01; p=0.091.Lean patients, rather than obese patients are at greater risk

    Coronary heart disease is a major risk factor for left ventricular (LV) systolic dysfunction. However, limited data are available regarding long-term benefits of percutaneous coronary intervention (PCI) in the era of drug-eluting stent or coronary artery bypass grafting (CABG) in patients with LV systolic dysfunction with severe coronary artery disease. We identified 3,584 patients with 3-vessel and/or left main disease of 15,939 patients undergoing first myocardial revascularization enrolled in the CREDO-Kyoto PCI/CABG Registry Cohort-2. Of them, 2,676 patients had preserved LV systolic function, defined as an LV ejection fraction (LVEF) of >50% and 908 had impaired LV systolic function (LVEF≤50%). In patients with preserved LV function, 5-year outcomes were not different between PCI and CABG regarding propensity score-adjusted risk of all-cause and cardiac deaths. In contrast, in patients with impaired LV systolic function, the risks of all-cause and cardiac deaths after PCI were significantly greater than those after CABG (hazard ratio 1.49, 95% confidence interval 1.04 to 2.14, p=0.03 and hazard ratio 2.39, 95% confidence interval 1.43 to 3.98, p<0.01).

    This study sought to develop a novel parsimonious score for predicting technical success of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) performed using the hybrid approach. Predicting technical success of CTO PCI can facilitate clinical decision making and procedural planning. We analyzed clinical and angiographic parameters from 781 CTO PCIs included in PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) using a derivation and validation cohort (2:1 sampling ratio). Variables with strong association with technical success in multivariable analysis were assigned 1 point, and a 4-point score was developed from summing all points. The PROGRESS CTO score was subsequently compared with the J-CTO (Multicenter Chronic Total Occlusion Registry in Japan) score in the validation cohort. Technical success was 92.9%. On multivariable analysis, factors associated with technical success included proximal cap ambiguity (beta coefficient [b] = 0.88), moderate/severe tortuosity (b = 1.18), circumflex artery CTO (b = 0.99), and absence of "interventional" collaterals (b = 0.88). The resulting score demonstrated good calibration and discriminatory capacity in the derivation (Hosmer-Lemeshow chi-square = 2.633; p = 0.268, and receiver-operator characteristic [ROC] area = 0.778) and validation (Hosmer-Lemeshow chi-square = 5.333; p = 0.070, and ROC area = 0.720) subset. In the validation cohort, the PROGRESS CTO and J-CTO scores performed similarly in predicting technical success (ROC area 0.720 vs. 0.746, area under the curve difference = 0.026, 95% confidence interval = -0.093 to 0.144). The PROGRESS CTO score is a novel useful tool for estimating technical success in CTO PCI performed using the hybrid approach. Copyright © 2016 American College of Cardiology Foundation.

    The value of multivessel percutaneous coronary intervention (MV-PCI) in patients with cardiogenic shock (CS) and multivessel disease (MVD) is still unclear because randomized controlled trials are missing. Therefore, we sought to evaluate the impact of MV-PCI on in-hospital outcomes of patients with MVD presenting with CS: 336 patients with acute myocardial infarction complicated by CS and ≥70% stenoses in ≥2 major epicardial vessels were included in this analysis of the Euro Heart Survey PCI registry. Patients undergoing MV-PCI (n = 82, 24%) were compared to those with single-vessel PCI (n = 254, 76%). The rate of 3-vessel disease (60% vs 57%, p = 0.63) was similar in the 2 cohorts. Presentation with resuscitation (48 vs 46%, p = 0.76) and ST-segment elevation myocardial infarction (83 vs 87%, p = 0.31) was frequent in patients with MV-PCI and single-vessel PCI. Patients with ventilation were more likely to receive MV-PCI (30% vs 19%, p = 0.05). There was a tendency toward a higher hospital mortality in patients with MV-PCI (48.8% vs 37.4%, p = 0.07). After adjustment for confounding variables, no significant difference for in-hospital mortality (odd ratio [OR] 1.28, 95% confidence interval [CI] 0.72 to 2.28) could be observed between the 2 groups. Age (OR 1.41, 95% CI 1.13 to 1.77), 3-vessel disease (OR 1.78, 95% CI 1.04 to 3.03), ventilation (OR 3.01, 95% CI 1.59 to 5.68), and previous resuscitation (OR 2.55, 95% CI 1.48 to 4.39) were independent predictors of hospital death. In conclusion, MV-PCI is currently used in only 1/4 of patients with CS and MVD. An additional nonculprit PCI was not associated with a survival benefit in these high risk patients.

    Although coronary artery disease (CAD) is common in patients with heart failure (HF), little is known about the prognostic significance of coronary lesion complexity in patients with prior HF undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate whether the coronary Synergy between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery (SYNTAX) score could improve risk stratification in HF patients with CAD. Two hundred patients (mean age 73 ± 11 years, left ventricular ejection fraction 49 ± 15 %) with prior HF who underwent PCI were divided into two groups stratified by SYNTAX score (median value 12) and tracked prospectively for 1 year. The study endpoint was the composite of major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, stroke, and hospitalization for worsening HF. Adverse events were observed in 39 patients (19.5 %). Patients with high SYNTAX scores (n = 100) showed worse prognoses than those with low scores (n = 100) (26.0 vs. 13.0 %, respectively, P = 0.021). In multivariate Cox-regression analysis, SYNTAX score ≥12 was significantly associated with MACE (hazard ratio: 1.99, 95 % confidence interval: 1.02-3.97; P = 0.045). In patients with prior HF and CAD, high SYNTAX scores predicted a high incidence of MACE. These results suggest that the SYNTAX score might be a useful parameter for improving risk stratification in these patients.

    High success rates are achievable for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using the hybrid approach, but periprocedural complications remain of concern. Although scores estimating success and efficiency in CTO PCI have been developed, there is currently no available score for estimation of the risk for periprocedural complications. We sought to develop a scoring tool for prediction of periprocedural complications during CTO PCI. We analyzed data from 1569 CTO PCIs in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (PROGRESS CTO) using a derivation and validation sampling ratio of 2:1. Variables independently associated with periprocedural complications in multivariable analysis in the derivation set were assigned points based on their respective odds ratios. Forty-four (2.8%) patients experienced complications. Three factors were independent predictors of complications and were included in the score: patient age >65 years, +3 points (odds ratio, OR=4.85, CI 1.82-16.77); lesion length ≥23 mm, +2 points (OR=3.22, CI 1.08-13.89); and use of the retrograde approach +1 point (OR=2.41, CI 1.04-6.05). The resulting score showed good calibration and discriminatory capacity in the derivation (Hosmer-Lemeshow χ(2) 6.271, P=0.281, receiver-operating characteristic [ROC] area=0.758) and validation (Hosmer-Lemeshow χ(2) 4.551, P=0.473, ROC area=0.793) sets. Score values of 0 to 2, 3 to 4, and ≥5 were defined as low, intermediate, and high risk of complications (derivation cohort 0.4%, 1.8%, 6.5%, PCTO complication score is a useful tool for prediction of periprocedural complications in CTO PCI.

    To investigate the impact of the success or failure of chronic total occlusion (CTO) interventions on the clinical outcomes in the current drug-eluting stent (DES) era. The impact of the successful CTO intervention on long-term clinical outcomes still remains unclear. Between 2007 and 2009, a total of 2568 patients with CTO were followed in a multicenter Korean CTO registry. Of these, successful recanalization with DESs occurred in 2045 patients (successful CTO group), whereas failure occurred in 523 patients (failed CTO group). The occurrence of the composite of cardiac death and myocardial infarction (MI) was compared between the successful CTO and failed CTO groups. During follow-up (median duration, 729 days), the occurrence of cardiac death or MI was significantly lower in the successful CTO group than in the failed CTO group (1.7% vs 3.3%; hazard ratio, 0.50; 95% confidence interval, 0.28-0.91; P=.02) and the cumulative occurrence in the successful CTO group was also significantly lower than in the failed CTO group (1.7% vs 3.0%; P=.03) by the Kaplan-Meier method. The successful CTO group had a significantly lower need for bypass surgery than the failed CTO group (0.2% vs 2.5%; PCTO (odds ratio, 0.51; 95% CI, 0.29-0.92) was significantly predictive of the occurrence of cardiac death or MI, together with age and left ventricular ejection fraction CTO intervention with DESs compared to failed CTO intervention was associated with lower event rates during follow-up.

    Effects of daily fluctuation of ambient temperature and concentrations of air pollutants on acute cardiovascular events have not been well studied. From January 2011 to December 2012, a total of 56,863 consecutive ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention were registered from 929 institutes with median interinstitutional distance of 2.6 km. We constructed generalized linear mixed models in which the presence or absence of patients with STEMI per day per institute was included as a binomial response variable, with daily meteorologic and environmental data obtained from their respective observatories nearest to the institutes (median distance of 9.7 and 5.6 km) as the explanatory variables. Both lower mean temperature and increase in maximum temperature from the previous day were independently associated with the STEMI occurrence throughout the year (odds ratio [OR] 0.925, 95% confidence interval [CI] 0.915 to 0.935, per 10°C, p variables. Both the absolute value and relative change in the ambient temperature were associated with the occurrence of STEMI; the associations with the air pollutant levels were less clear after adjustment for these meteorologic variables in Japan.

    Full Text Available Objectives: The aim of the study was to investigate the in-hospital and one-year clinical outcome of patients treated with percutaneous coronary intervention (PCI in a tertiary hospital in Oman. Methods: We conducted a retrospective, single-center, observational study looking at patients > 18 years old who underwent a PCI from 1 January to 31 December 2013. The primary end point was the occurrence of a major adverse cardiovascular event (MACE, defined as death, any myocardial infarction (MI, cerebrovascular accident (CVA, and target vessel revascularization (TVR with either repeat PCI or coronary artery bypass surgery (CABG. Secondary end-points included procedural success rate, angina status, stent thrombosis, and the rate of redo-PCI/CABG for in-stent restenosis. Results: A total of 1 045 consecutive patients were analyzed. The mean age of the cohort was 58.2±11.2 years. Hyperlipidemia (66.8%, hypertension (55.1%, and diabetes mellitus (45.9% were the predominant risk factors. Stable angina, ST-elevation MI, non-ST-elevation MI, and post-acute coronary syndrome (ACS were common indications (approximately 20.0% each. The angiographic and procedural success rate was 95.0%. Forty-six percent of patients had single-vessel disease, 34.4% had double vessel disease, and triple vessel disease was seen in 19.1% of patients. Ninety-eight percent had balloon angioplasty with stenting, and only 1.9% of patients had balloon angioplasty without stenting. The majority of patients had single-vessel stenting (81.3%. A drug-eluting stent was used in 88.4% of patients, and a bare-metal stent in 11.6%. In-hospital MACE was 3.6%. There were 19 in-hospital deaths (1.8%, and four patients (0.4% had CVA/MI. Out of 1 026 patients discharged, 100 patients were lost to follow-up. Among the 926 patients followed-up, 673 patients (72.7% were asymptomatic. One-year MACE was 17.0%, including 5.0% death and 6.0% MI. Repeat revascularization was performed in 53 patients (5

    Although epidemiologic studies have shown the impact of height on occurrence and/or prognosis of cardiovascular diseases, the underlying mechanism is unclear. In addition, the relation in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) remains unknown. We sought to assess the influence of height on outcomes of patients with acute STEMI undergoing primary PCI and to provide a pathophysiological explanation. All 1,490 patients with STEMI undergoing primary PCI were analyzed. Major adverse cardiac and cerebrovascular events (MACCE) were defined as all-cause mortality, nonfatal myocardial infarction, nonfatal stroke, and unplanned hospitalization for heart failure (HF). Patients were divided into (1) MACCE (+) versus MACCE (-) and (2) first- to third-tertile groups according to height. MACCE (+) group was shorter than MACCE (-) group (164 ± 8 vs 166 ± 8 cm, p = 0.012). Prognostic impact of short stature was significant in older (≥70 years) male patients even after adjusting for co-morbidities (hazard ratio 0.951, 95% confidence interval 0.912 to 0.991, p = 0.017). The first-tertile group showed the worst MACCE-free survival (p = 0.035), and most cases of MACCE were HF (n, 17 [3%] vs 6 [1%] vs 2 [0%], p = 0.004). On post-PCI echocardiography, left atrial volume and early diastolic mitral velocity to early diastolic mitral annulus velocity ratio showed an inverse relation with height (p <0.001 for all) despite similar left ventricular ejection fraction. In conclusion, short stature is associated with occurrence of HF after primary PCI for STEMI, and its influence is prominent in aged male patients presumably for its correlation with diastolic dysfunction.

    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 (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 <75 years, no definite increase in major bleeding was seen for elderly patients (aged ≥75 years).

    The anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva with interarterial, intramural, and/or intraconal course is a rare congenital anomaly that is associated with a high risk of sudden death in children. The Congenital Heart Surgeons' Society established the Registry of Anomalous Aortic Origin of the Coronary Artery to help determine the outcome of children and young adults managed with surgical intervention versus observation and to test the hypothesis that subsets of patients with anomalous aortic origin of a coronary artery can be identified in whom the risk of intervention is less than the risk of observation. All institutional members of the Congenital Heart Surgeons' Society were recruited for participation. The registry consists of a retrospective cohort of patients diagnosed between 1 January, 1998 and 20 January, 2009 and a prospective, population-based cohort of patients newly diagnosed from 21 January, 2009 onwards. Baseline demographics, diagnoses, and results of tests will be obtained through a review of the medical records. Annual follow-up data will be collected. Data will be analysed for different factors of risk at diagnosis, different strategies of treatment, and the impact of both on the outcomes of the patients. As of June 2010, 28 institutions had applied for approval from their institutional review board and 16 institutions had received approval from their institutional review board. Seventy-four patients have enrolled to date. We hope to use the established Pediatric Cardiomyopathy Registry as a guide to successful implementation, with a cooperative effort between institutions. The overall purpose of the Registry of Anomalous Aortic Origin of the Coronary Artery is to determine the outcome of surgical intervention versus observation in children and young adults with anomalous aortic origin of a coronary artery, and to describe the natural and "unnatural" history of these patients over the course of their lifetime

    Context Despite the widespread use of percutaneous coronary intervention (PCI), the appropriateness of these procedures in contemporary practice is unknown. Objective To assess the appropriateness of PCI in the United States. Design, Setting, and Patients Multicenter, prospective study of patients within the National Cardiovascular Data Registry undergoing PCI between July 1, 2009, and September 30, 2010, at 1091 US hospitals. The appropriateness of PCI was adjudicated using the appropriate use criteria for coronary revascularization. Results were stratified by whether the procedure was performed for an acute (ST-segment elevation myocardial infarction, non–ST-segment elevation myocardial infarction, or unstable angina with high-risk features) or nonacute indication. Main Outcome Measures Proportion of acute and nonacute PCIs classified as appropriate, uncertain, or inappropriate; extent of hospital-level variation in inappropriate procedures. Results Of 500 154 PCIs, 355 417 (71.1%) were for acute indications (ST-segment elevation myocardial infarction, 103 245 [20.6%]; non–ST-segment elevation myocardial infarction, 105 708 [21.1%]; high-risk unstable angina, 146 464 [29.3%]), and 144 737 (28.9%) for nonacute indications. For acute indications, 350 469 PCIs (98.6%) were classified as appropriate, 1055 (0.3%) as uncertain, and 3893 (1.1%) as inappropriate. For nonacute indications, 72 911 PCIs (50.4%) were classified as appropriate, 54 988 (38.0%) as uncertain, and 16 838 (11.6%) as inappropriate. The majority of inappropriate PCIs for nonacute indications were performed in patients with no angina (53.8%), low-risk ischemia on noninvasive stress testing (71.6%), or suboptimal (≤1 medication) antianginal therapy (95.8%). Furthermore, although variation in the proportion of inappropriate PCI across hospitals was minimal for acute procedures, there was substantial hospital variation for nonacute procedures (median hospital rate for inappropriate PCI, 10

    Randomized controlled trials have shown improved short-term bleeding outcomes for bivalirudin compared to other anticoagulant in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). This study analyzed the cost/efficacy profile of bivalirudin-based anticoagulation strategy versus non bivalirudin-based anticoagulant strategy without use of GP IIb/IIIa inhibitors in routine clinical practice. From January 2009 to December 2010, 216 patients who underwent PCI for ACS at hospital Georges-Pompidou without GP IIb/IIIa inhibitors were studied. Of these patients, 24 (11%) received bivalirudin and 192 (88%) received others anticoagulants (mainly unfractionated heparin or low molecular weight heparin). Ischemic events and bleeding or transfusion were slightly lower in bivalirudin group (0 vs. 4.2%, P=0.60 and 4.2 vs. 8.9%, P=0.70, respectively). In spite of a higher cost of the medication, the overall cost of the bivalirudin strategy was slightly lower (9167±3688 € vs. 14,016±14,749 €, P=0.23), in relation with a shorter average duration of the hospital stay. In conclusion, in this limited, single-center, population of patients with ACS, the clinical efficacy and safety of bivalirudin appeared at least as good as that of reference anticoagulants in real world clinical practice, with no increase in overall costs.

    Background The benefit of statin use after acute ST-segment elevation myocardial infarction (STEMI) has been well established, however, the influence of the timing of statin administration has not been elucidated. The objective of this study focused on early clinical outcomes after percutaneous coronary intervention (PCI). Methods This analysis of the Korea Working Group on Myocardial Infarction registry (KorMI) study included 3,584 STEMI patients (mean age, 63 ±13 years;male, 2,684, 74.9%) undergoing PCI from January 2008 to June 2009. Rates of major adverse cardiac events (MACE:all-cause death, recurrent MI, and target lesion revascularization) were compared among patients grouped according to statin therapy timing:I, both during and after hospitalization (n=2,653, 74%);II, only during hospita-lization (n=309, 8.6%);III, only after discharge (n=157, 4.4%);and IV, no statin therapy (n=465, 13%). Mean follow-up duration was 234 ± 113 days. Results Multivariate factors of statin use during hospitalization included prior statin use, multiple diseased vessels, final thrombolysis in myocardial infarction flow grade III, and low-density lipoprotein cholesterol level. At 6-month follow-up, groups III and IV had the highest MACE rates (2.3%, 3.9%, 5.1%, and 4.9%for groups I-IV, respectively, P=0.004). After adjusting for confounders, groups II-IV had a higher MACE risk than group I [hazard ratio (HR):3.20, 95%confidence interval (95%CI):1.31-7.86, P=0.011;HR:3.84, 95%CI:1.47-10.02, P=0.006;and HR:3.17, 95%CI:1.59-6.40, P=0.001;respectively]. Conclusions This study, based on the national registry database, shows early and continuous statin therapy improvs early outcomes of STEMI patients after PCI in real-world clinical prac-tice.

  11. 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.

  12. Debate over patient-centered care: percutaneous coronary intervention or coronary artery bypass grafting?

    Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) have developed as effective therapies to treat coronary artery disease. Initial CABG is associated with lower mortality than initial medical management, especially among high- and intermediate-risk patients with coronary artery disease. However, PCI is currently the most frequent initial treatment delivered by interventional cardiologists to treat multivessel coronary artery disease, despite substantial evidence from meta-analyses of randomized trials and registry data favoring CABG. Recent advancements in PCI did not result in detectable improvements in death or myocardial infarction compared with medical therapy, although significant reductions in target lesions or vessel revascularization were identified after implantation of a drug-eluting stent (DES) rather than a bare-metal stent. The SYNTAX trial compared patients with left main and/or three-vessel coronary artery disease treated with DES or CABG. The results of the trial demonstrated the 1-year inferiority of PCI compared with CABG with respect to major adverse cardiac and cerebrovascular events. Nevertheless, patients with coronary artery disease continue to receive more recommendations for PCI and fewer for CABG than are indicated in the guidelines. A multidisciplinary team approach should be the standard of care when recommending interventions for treating complex coronary artery disease among patients for whom CABG is superior in terms of survival and freedom from reintervention.

    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.

    Full Text Available 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 (p<0.0001 for both.Combined CI-AKI after index procedure and HLI on admission is associated with poor clinical outcomes in patients with STEMI who underwent primary PCI.

    There is a paucity of data on the temporal trends of cardiovascular risk factors in patients undergoing percutaneous coronary intervention (PCI). We investigated the secular trends of risk profiles of patients undergoing PCI without prior history of cardiovascular disease (CVD). CVD risk factors are changed over time. This time-trend analysis from 1994 to 2010 was performed within the Mayo Clinic PCI Registry. Outcome measures were prevalence of CVD risk factors, including the Framingham risk score (FRS), at the time of admission for PCI. During this period, 12,055 patients without a history of CVD (mean age, 65.0 ± 12.4 years, 67% male) underwent PCI at the Mayo Clinic. Age distribution slightly shifted toward older age (P for trend trend trend trend trend <0.001), whereas smoking prevalence did not change. The current study demonstrates that although traditional FRS and its associated predicted 10-year cardiovascular risk declined over time, the prevalence of risk factors increased in patients undergoing PCI. The study suggests the need for a new risk-factor assessment in this patient population. © 2014 Wiley Periodicals, Inc.

    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.

    The risk of stroke in patients hospitalized with an acute coronary syndrome (ACS) ranges from ischemic stroke in patients with ACS to help guide clinicians in the acute management of these high-risk patients. Data were obtained from 63,118 patients enrolled from April 1999 to December 2007 in the Global Registry of Acute Coronary Events (GRACE), a multinational registry involving 126 hospitals in 14 countries. A regression model was developed to predict the occurrence of in-hospital ischemic stroke in patients hospitalized with an ACS. The main study outcome was the development of ischemic stroke during the index hospitalization for an ACS. Eight risk factors for stroke were identified: older age, atrial fibrillation on index electrocardiogram, positive initial cardiac biomarkers, presenting systolic blood pressure ≥ 160 mm Hg, ST-segment change on index electrocardiogram, no history of smoking, higher Killip class, and lower body weight (c-statistic 0.7). The addition of coronary artery bypass graft surgery and percutaneous coronary intervention into the model increased the prediction of stroke risk. In conclusion, the GRACE stroke risk score is a simple tool for predicting in-hospital ischemic stroke risk in patients admitted for the entire spectrum of ACS, which is widely applicable to patients in various hospital settings and will assist in the management of high-risk patients with ACS.

    2013-01-15

    Background: Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for patients with ST-segment-elevation myocardial infarction (STEMI), but some concerns remain about its safety and efficacy in centers without on-site cardiac surgery (OCS). Methods: The Infermi Hospital in Rivoli, Italy, is a community hospital without OCS with a high volume catheterization laboratory (> 800 PCI and > 150 primary PCI per year), which provides a 24-hour primary PCI service to a population of 583.000 and is only 14 km far from the nearest OCS hospital. We analyzed clinical and procedural data, as well as 30-day outcome, of all STEMI patients treated by primary PCI within 12 hours from symptom onset. Results: From September 2001 to June 2010, 1302 patients with a suspect of STEMI underwent urgent coronary angiography. Of these, 1251 (96.1%), underwent primary PCI. A successful myocardial revascularization was achieved in 1172 patients (93.7%). Thirty-day mortality occurred in 7.1%. Multivariate predictors of 30-day mortality were: age ≥ 75 years (OR 3.96, p = 0.0003), left ventricular ejection fraction ≤ 40% (OR 35.0, p = 0.02), cardiogenic shock at presentation (OR 33.4, p < 0.0001), anterior STEMI (OR 1.82, p = 0.036) and total ischemic time ≤ 3 hours (OR 0.55, p = 0.05). Conclusions: Primary PCI is a reperfusion strategy feasible and effective in unselected high-risk STEMI patients even in hospitals without OCS with a high volume of routine and emergency interventional procedures.

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

    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.

    Background: Recent studies have shown fondaparinux's superiority over enoxaparin in patients with non-ST elevation acute coronary syndrome (ACS), especially in relation to bleeding reduction. The description of this finding in a Brazilian registry has not yet been documented. Objective: To compare fondaparinux versus enoxaparin in in-hospital prognosis of non-ST elevation ACS. Methods: Multicenter retrospective observational study. A total of 2,282 patients were included (335 in the fondaparinux group, and 1,947 in the enoxaparin group) between May 2010 and May 2015. Demographic, medication intake and chosen coronary treatment data were obtained. Primary outcome was mortality from all causes. Secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). Comparison between the groups were done through Chi-Square test and T test. Multivariate analysis was done through logistic regression, with significance values defined as p < 0.05. Results: With regards to treatment, we observed the performance of a percutaneous coronary intervention in 40.2% in the fondaparinux group, and in 35.1% in the enoxaparin group (p = 0.13). In the multivariate analysis, we observed significant differences between fondaparinux and enoxaparin groups in relation to combined events (13.8% vs. 22%. OR = 2.93, p = 0.007) and bleeding (2.3% vs. 5.2%, OR = 4.55, p = 0.037), respectively. Conclusion: Similarly to recently published data in international literature, fondaparinux proved superior to enoxaparin for the Brazilian population, with significant reduction of combined events and bleeding.

    Coronary artery disease is one of the most rampant non-communicable diseases in the world. It begins indolently as a fatty streak in the lining of the artery that soon progresses to narrow the coronary arteries and impair myocardial perfusion. Often the atherosclerotic plaque ruptures and causes sudden thrombotic occlusion and acute ST-elevation myocardial infarction (STEMI), non-ST-elevation MI (NSTEMI) or unstable angina (UA). This phenomenon is called acute coronary syndrome (ACS) and is the leading cause of death not only in Malaysia but also globally. In order for us to tackle this threat to the health of our nation we must arm ourselves with reliable and accurate information to assess current burden of disease resources available and success of current strategies. The acute coronary syndrome (ACS) registry is the flagship of the National Cardiovascular Disease Database (NCVD) and is the result of the dedicated and untiring efforts of doctors and nurses in both public and private medical institutions and hospitals around the country, ably guided and supported by the National Heart Association, the National Heart Foundation, the Clinical Research Centre and the Ministry of Health of Malaysia. Analyses of data collected throughout 2006 from 3422 patients with ACS admitted to the 12 tertiary cardiac centres and general hospitals spanning nine states in Malaysia in this first report has already revealed surprising results. Mean age of patients was 59 years while the most consistent risk factor for STEMI was active smoking. Utilization of medications was high generally. Thirty-day mortality for STEMI was 11%, for NSTEMI 8% and UA 4%. Thrombolysis (for STEMI only) reduced in-hospital and 30-day mortality by nearly 50%. Percutaneous coronary intervention or PCI also reduced 30-day mortality for patients with non-ST elevation MI and unstable angina. The strongest determinants of mortality appears to be Killip Class and age of the patient. Fewer women received

    The technique of obtaining an epicardial electrocardiogram trace by connecting the guidewire during coronary angioplasty to an electrocardiogram lead has been used since 1985. The intracoronary electrocardiogram appears to be more sensitive than the surface electrocardiogram in detecting transient ischemia, particularly in the territory of the left anterior descending and left circumflex coronary arteries. Importantly, recent studies have shown the intracoronary electrocardiogram to be particularly useful in demonstrating pre- and postconditioning during interventional procedures, predicting periprocedural myocardial damage, and in the determination of regional viability in the catheterization laboratory. Barriers to the use of the intracoronary electrocardiogram in the clinical setting include the lack of standardized methods for acquiring and analyzing the intracoronary electrocardiogram, and the lack of commercially available continuous intracoronary monitoring systems to permit analysis while performing coronary interventions. Facilitating these relatively simple technical developments may permit optimal integration of the intracoronary electrocardiogram into the catheterization laboratory.

    The incidence of patients subjected to emergency coronary artery bypass graft (CABG) after percutaneous coronary intervention (PCI) is decreasing due to improvement of PCI technique and device technology. The aim of our study is to evaluate cases subjected to emergency CABG after complicated PCI to determine incidence, indications and results of surgery and to compare them with other emergency cases which are not related to angioplasty or stenting. From April 1999 to December 2005, 1 200 patients who underwent PCI were analysed. Those patients who developed complications related to PCI and required surgical intervention were included (PCI group N.=31). These patients were compared with other emergency cases not related to PCI (non-PCI group N.=48). The selection of these patients was based on the criteria of the Society of Thoracic Surgeons. The incidence of PCI complications which necessitated emergency surgical intervention was 2.6%. The main indication was due to unsatisfactory angioplasty with ongoing myocardial ischemia (68%), stent thrombosis (13%), dissection (10%) retained angioplasty wire (6.5%), and perforation (3%). The incidence of cardiogenic shock, ongoing ischemia, acute infarction Emergency coronary artery bypass grafting among patients with PCI complications and those patients not related to PCI is associated with high mortality and morbidity. Although, the percentage of mortality and morbidity was more among PCI patients the difference between both groups was not significant. Surgical backup and collaboration between cardiologist and surgeons is needed to reduce delay in management and patients transfer to obtain the best surgical outcome.

  13. Kissing balloon inflation in percutaneous coronary interventions.

    Bifurcation lesions are the most frequently approached complex coronary lesions in everyday interventional practice. Bifurcations complexity relies essentially on their very specific anatomy that is imperfectly handled by current coronary devices and, despite dedicated techniques and drug-eluting stents, percutaneous coronary interventions directed toward the treatment of bifurcations are technically demanding and require proper execution. Kissing balloon (KB) inflation was the first specific bifurcation technique to have been developed for percutaneous bifurcation interventions and continues to currently play an important role. Indeed, KB has been proposed to optimize stent apposition, improve side branch access while correcting stent deformation or distortion. Over the years, the KB technique has been deeply investigated by many different methods, from bench testing and computer simulations to in vivo intravascular imaging and clinical studies, producing a large amount of data pointing out the benefits and limitations of the technique. We sought to provide here a comprehensive overview of all those aspects. Copyright © 2012 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

    Patients with acute coronary syndrome complicated with high degree atrioventricular block still have a high mortality. A low percentage of these patients need a permanent pacemaker (PPM) but mortality and associated factors with the PPM implant in acute coronary syndrome patients are not known. We assess whether PPM implant is an independent variable in the mortality of acute coronary syndrome patients. Also, we explored the variables that remain independently associated with PPM implantation. This was an observational study on the Spanish ARIAM register. The inclusion period was from January 2001 to December 2011. This registry included all Andalusian acute coronary syndrome patients. Follow-up for global mortality was until November 2013. We selected 27,608 cases. In 62 patients a PPM was implanted (0.024%). The mean age in PPM patients was 70.71±11.214 years versus 64.46±12.985 years in patients with no PPM. PPM implant was associated independently with age (odds ratio (OR) 1.031, 95% confidence interval (CI) 1.007-1.055), with left ventricular branch block (OR 6.622, 95% CI 2.439-18.181), with any arrhythmia at intensive care unit admission (OR 2.754, 95% CI 1.506-5.025) and with heart failure (OR 3.344, 95% CI 1.78-8.333). PPM implant was independently associated with mortality (OR 11.436, 95% CI 1.576-83.009). In propensity score analysis PPM implant was still associated with mortality (OR 5.79, 95% CI 3.27-25.63). PPM implant is associated with mortality in the acute coronary syndrome population in the ARIAM registry. Advanced age, heart failure, arrhythmias and left ventricular branch block at intensive care unit admission were found associated factors with PPM implant in acute coronary syndrome patient.

    Background Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China. Methods Between March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.Results During hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary Intervention (PCI) within 6 months was more common in patients with RA, P<0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P=0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA,P=0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P<0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P=0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P=0.006; and beta-blockers 176(64.0%) versus 864 (74

    During a 14-month period, 6 experienced centers prospectively enrolled 271 patients into a registry in which percutaneous transluminal coronary angioplasty was the primary treatment for acute myocardial infarction. Patients age > 18 years who presented with ST-segment elevation on the 12-lead electrocardiogram were enrolled if symptom duration was or = 2 units of blood occurred in 46 patients (18%); 14 of these transfusions were related to coronary artery bypass surgery. Primary angioplasty is associated with a high reperfusion rate, low in-hospital mortality and few recurrent myocardial ischemic events. These results point to the need for a large-scale trial comparing angioplasty with thrombolytic therapy in the setting of acute myocardial infarction.

    The Russian Acute Coronary Syndrome Registry (RusACSR) is a retrospective, continuous, nationwide, Web-based registry of patients with acute coronary syndromes (ACS). The RusACSR is a database that uses a secure Web-based interface for data entry by individual users. Participation in the RusACSR is voluntary. Any clinical center that provides health care to ACS patients can take part in the RusACSR. The RusACSR enrolls ACS patients who have undergone care in Russian hospitals from February 2008 to the present. Key data elements and methods of data analysis in the RusACSR are presented in this article. Up to 2015, 213 clinical centers from 36 regions of Russia had participated in the RusACSR. Currently, the database contains data on more than 250 000 ACS patients who underwent care from 2008 to 2015. Some current problems are highlighted in this article. The RusACSR is a perspective project for different epidemiologic studies in Russian ACS patients.

  5. Magnetic navigation in percutaneous coronary intervention.

    2006-12-01

    Magnetic navigation is the use of adjustable magnetic fields to precisely direct wires and equipment for clinical applications. It is a recently developed option that is now available for interventional cardiology. Procedures are based on the production of a three-dimensional reconstruction of the vessel lumen from standard angiographic images. Knowledge of the positions of the table and image intensifier during angiography allows calculation of the vessel coordinates in real space within the patient's chest. The applied magnetic field can be changed at any time to redirect the wire tip in order to improve navigation through complex and tortuous anatomy. The digital information of the coronary reconstruction can be used in further novel ways. Firstly, the integration of multislice computerized tomography images adds information about the path of the previous lumen of chronic total occlusions. Secondly, the computed center-line of the reconstructed vessel can be superimposed onto the live fluoroscopy images as a three-dimensional guide. The combination of improved navigation together with the other available system features may improve time, contrast, and material usage in a range of coronary lesions. Future potential developments include improvements in equipment and software, and potential therapeutic strategies under consideration include the use of equipment to perform remote control procedures, and the integration of the system to improve bone marrow-derived stem cell delivery.

    We sought to evaluate the effect of cigarette smoking on long-term outcomes after successful percutaneous coronary intervention for chronic total occlusion (CTO) lesions. Cigarette smoking promotes the progression of atherosclerosis but enhances the antiplatelet effect of clopidogrel. The Korea National Registry of CTO Intervention included 2,167 patients with CTO lesions from 26 centers who were successfully revascularized with drug-eluting stents from 2007 to 2009. Thrombotic events were defined as the composite of cardiac death, nonfatal myocardial infarction, and stent thrombosis. Current-smokers had more favorable baseline characteristics such as a younger age and lower prevalence of hypertension and diabetes mellitus. At 1 year, current-smokers had a significantly lower thrombotic event rate (1.1% vs. 2.7%, P = 0.034), but a significantly higher target vessel revascularization (TVR) rate (7.2% vs. 4.2%, P = 0.017) compared with never-smokers. After adjustment, current-smoking was independently associated with a 72% decreased risk for thrombotic events, and 73% increased risk for TVR. In patients with a revascularized CTO lesion, cigarette smoking is associated with fewer thrombotic events but with a higher incidence of TVR. Patients with CTO may benefit from smoking cessation to reduce TVR in conjunction with the use of new more potent antiplatelet agents whose effect is independent of cigarette smoking to improve thrombotic events. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    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.

Among the 49 patients who had indications for DAT that was used in 15 (30.6 % cases and that was not in 3 (6.1 % patients in the presence of contraindications, 25 (51.0 % did not receive DAT in the absence of contraindications and 6 (12.3 % patients received the therapy in the presence of contraindications. Conclusion. DAT prescribed by outpatient physicians does not always meet the current CG. There are cases of not using DAT in the presence of obvious indications for DAT and, on the contrary, those of its use in the presence of contraindications.

    Full Text Available Cardiovascular abnormalities are well-known manifestations of tertiary syphilis infections which although not frequent, are still causes of morbidity and mortality. A less common manifestation of syphilitic aortitis is coronary artery ostial narrowing related to aortic wall thickening. We report a case of a 46-year-old male admitted due to acute anterior ST elevation myocardial infarction submitted to primary percutaneous coronary intervention successfully. Coronary angiography showed a suboccluded ostial lesion of left main coronary artery. VDRL was titrated to 1/512. The patient was discharged with treatment including benzathine penicillin. Previous case reports of acute myocardial infarction in association with syphilitic coronary artery ostial stenosis have been reported, but the fact that the patient was treated by percutaneous coronary intervention is unique in this case.

    Among patients undergoing coronary procedures, patients with coronary artery bypass grafts represent an important, high risk subgroup. Routine transradial approach may be successfully adopted in these patients to reduce access-site complications. However, transradial cannulation of the grafts may result technically demanding. In this article we discuss the specific technical issues and we present a series of tips and tricks which may facilitate angiography and interventions on both internal mammary and aorto-coronary grafts.

    The indications for Excimer laser coronary atherectomy (ELCA) have been refined in modern interventional practice. With the expanding role for optical coherence tomography (OCT) providing high-resolution intra-coronary imaging, this article examines the appearance of the coronary lumen after ELCA. Each indication for ELCA is discussed and illustrated with a clinical case, followed by detailed analysis of the OCT imaging pre and post ELCA. The aim of the article is to provide information to interventional cardiologists to facilitate decision making during PCI, when ELCA has been used as part of the interventional strategy.

Several complications may arise after coronary intervention for coronary lesions that interfere with treatment, and the incidence of coronary arterial complications due to invasive therapy remains unclear. Further, the long-term outcomes in patients with Behçet’s disease after stenting for acute myocardial infarction have not been described. The present report describes a 35-year-old Japanese man with Behçet’s disease who developed acute myocardial infarction. A coronary aneurysm developed at the stenting site of the left anterior descending coronary artery, along with stenosis in the left anterior descending segment proximal to the site. Although invasive therapy was considered, medication including immunosuppressants was selected because of the high risk of vascular complications after invasive therapy. The coronary artery disease has remained asymptomatic for the 4 years since the patient started medication. This case underscores the importance of considering the incidence of coronary arterial complications and of conservative treatment when possible.Keywords: Behçet’s disease, myocardial infarction, coronary arterial complications, percutaneous coronary intervention, immunosuppressants

    Full Text Available Substantial geographic variation exists in percutaneous coronary intervention (PCI use across the United States. It is unclear the extent to which high PCI utilization can be explained by PCI for inappropriate indications. The objective of this study was to examine the relationship between PCI rates across regional healthcare markets utilizing hospital referral regions (HRRs and PCI appropriateness.The number of PCI procedures in each HRR was obtained from the 2010 100% Medicare limited data set.

    Objectives To determine the validity and applicability of the global registry of acute coronary events (GRACE) pre-diction model for in-hospital mortality in all forms of acute coronary syndrome (ACS) in a sub population of Chongqing. Methods Data of 669 ACS patients were collected retrospectively from Jan 2005 to Apr 2008 and were re-corded on a standardized case report form. For each patient the GRACE risk score (GRACE RS) was calculated (using the GRACE calculator available from the grace website) using specific variables collected at admission. Patients with missing data and those transferred from other hospitals were excluded. Receiver operating characteristic (ROC) curves were plotted for the GRACE risk score. Results Among 576 ACS patients, 98 (17.01%), 36 (6. 25 %), and 442 (76. 74 %) presented with ST-elevation myocardial infarction (MI), non-ST elevation MI and unstable angina, re-spectively. The GRACE risk score could not be determined in 91 (9. 3 %) patients due to missing data or for patients who were transferred from other hospitals and were excluded from the analysis. The median GRACE risk score was 133 (interquartile range: 92 - 174) and, the in-hospital rates of death and death/(re-) MI were 6. 1% and 7.6 %, respec-tively. The GRACE risk score demonstrated excellent discrimination (c-statistic = 0. 86, 95 % CI 0. 79 - 0. 91, P < 0. 001) for in-hospital death/ (re) -MI. Conclusions The GRACE RS study had a good predictive accuracy for death or MI across the wide range of ACS in this population. It may be a useful risk stratification tool that helps identify high-risk patients who will benefit most from myocardial revascularization and low risk patients who may be spared from un-dergoing more aggressive interventional treatment.

    Full Text Available Haemophilia A is a rare genetic condition leading to coagulation factor VIII deficiency and thus predisposing to bleeding diathesis. Due to advances in treatment, life expectancy of haemophilia A sufferers is increasing, and the incidence and prevalence of coronary artery disease are rising. There have been many reported cases of acute myocardial infarction in such patients, who subsequently undergo elective percutaneous coronary intervention. We present the case of a 55-year-old gentleman presenting with an acute anterior full-thickness myocardial infarction who required emergency primary percutaneous coronary intervention.

    Background The value of American Board of Internal Medicine (ABIM) certification has been questioned. We evaluated the association of interventional cardiology (ICARD) certification with in-hospital outcomes of patients undergoing percutaneous coronary intervention (PCI) in 2010. Methods and Results We identified physicians who performed ≥10 PCIs in 2010 in the CathPCI Registry and determined ICARD status using ABIM data. We compared in-hospital outcomes of patients treated by certified and non-certified physicians using hierarchical multivariable models adjusted for differences in patient characteristics and PCI volume. Primary endpoints were all-cause in-hospital mortality and bleeding complications. Secondary endpoints included emergency coronary artery bypass grafting, vascular complications, and a composite of any adverse outcome. With 510,708 PCI procedures performed by 5,175 physicians, case mix and unadjusted outcomes were similar among certified and non-certified physicians. The adjusted risks of in-hospital mortality (OR 1.10, 95% CI 1.02-1.19) and emergency CABG (OR 1.32, 95% CI 1.12-1.56) were higher in the non-ICARD certified group, but the risks of bleeding, vascular complications, and the composite endpoint were not statistically significantly different between groups. Conclusions We did not observe a consistent association between ICARD certification and the outcomes of PCI procedures. Although there was a significantly higher risk of mortality and emergency CABG in patients treated by non-ICARD certified physicians, the risks of vascular complications and bleeding were similar. Our findings suggest that ICARD certification status alone is not a strong predictor of patient outcomes, and indicate a need to enhance the value of subspecialty certification. PMID:26384518

    to identify prognostic factors in the National Registry of Acute Coronary Syndromes. patients in medical care units with acute ischemic coronary syndrome (AICS) according to the criteria of the American Heart Association/American College of Cardiology/European Society of Cardiology, considering the GRACE score (GS) were studied. there were 2389 patients, 28.9 % women and 71.1 % men, mean age 63 ± 11.7 years; with AICS with ST-segment elevation (69.11 %) and 30.89 % with AICS without ST elevation. The average of GS was 168. A GS > 150 points in patients with AICS without ST elevation was associated with recurrent ischemia or angina (RR = 1.4, p = 0.05), left ventricular failure (RR = 3.1, p < 0.0001), stroke (RR = 2.9, p = 0.004) and arrhythmias (RR = 2.7, p < 0.0001). The patients with AICS with ST-segment elevation were associated with death (RR = 1.6, p = 0.01), reinfarction (RR = 1.7, p = 0.001), recurrent ischemia (RR = 1.2, p = 0.04), left ventricular failure (RR = 3.4, p < 0.001), stroke (RR = 3.9, p < 0.001) and arrhythmias (RR = 2.3, p < 0.001). Fibrinolytic therapy was used in 40.2 %. There was a negative correlation between GS and fibrinolytic therapy (r -0.04, p = 0.04). the AICS with ST-segment elevation is more frequent and have a high GS.

    Recent studies have shown fondaparinux's superiority over enoxaparin in patients with non-ST elevation acute coronary syndrome (ACS), especially in relation to bleeding reduction. The description of this finding in a Brazilian registry has not yet been documented. To compare fondaparinux versus enoxaparin in in-hospital prognosis of non-ST elevation ACS. Multicenter retrospective observational study. A total of 2,282 patients were included (335 in the fondaparinux group, and 1,947 in the enoxaparin group) between May 2010 and May 2015. Demographic, medication intake and chosen coronary treatment data were obtained. Primary outcome was mortality from all causes. Secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). Comparison between the groups were done through Chi-Square test and T test. Multivariate analysis was done through logistic regression, with significance values defined as p eventos combinados (choque cardiogênico, reinfarto, morte, acidente vascular cerebral e sangramentos). A comparação entre os grupos foi realizada por meio de Q-quadrado e teste-T. A análise multivariada foi realizada por regressão logística, sendo considerado significativo p eventos combinados (13,8% vs. 22%, OR = 2,93, p = 0,007) e sangramentos (2,3% vs. 5,2%, OR = 4,55, p = 0,037), respectivamente. Semelhante aos dados recentemente publicados na literatura mundial, fondaparinux mostrou-se superior à enoxaparina para a população brasileira, com redução significativa de eventos combinados e sangramentos.

    Noncardioembolic stroke and coronary heart disease (CHD) may share genetic predispositions. We tested the hypothesis that genetic variants which are associated with risk of CHD would also be associated with risk of noncardioembolic stroke in 562 cases from the Vienna Stroke Registry and 815 controls. We selected 6 gene variants that had been consistently associated with risk of CHD in 3 studies, including the Atherosclerosis Risk in Communities study, and found that 4 of these gene variants were also associated with risk of noncardioembolic stroke. The odds ratios for noncardioembolic stroke were 1.31 (90% CI 1.07–1.60) for rs3900940 in MYH15, 1.24 (90% CI 1.01–1.5) for rs20455 in KIF6, 1.21 (90% CI 0.99–1.49) for rs1010 in VAMP8, and 1.20 (90% CI 0.95–1.50) for rs10757274 on chromosome 9p21.

    Full Text Available Chronic kidney disease (CKD is strongly associated with coronary artery disease (CAD. We established a prospective observational nationwide multicenter registry to evaluate current treatment and outcomes in patients with both CKD and angiographically documented CAD.In 32 cardiological centers 3,352 CAD patients with ≥50% stenosis in at least one coronary artery were enrolled and classified according to their estimated glomerular filtration rate and proteinuria into one of five stages of CKD or as a control group.2,723 (81.2% consecutively enrolled patients suffered from CKD. Compared to controls, CKD patients had a higher prevalence of diabetes, hypertension, peripheral artery diseases, heart failure, and valvular heart disease (each p<0.001. Myocardial infarctions (p = 0.02, coronary bypass grafting, valve replacements and pacemaker implantations had been recorded more frequently (each p<0.001. With advanced CKD, the number of diseased coronary vessels and the proportion of patients with reduced left ventricular ejection fraction (LVEF increased significantly (both p<0.001. Percutaneous coronary interventions were performed less frequently (p<0.001 while coronary bypass grafting was recommended more often (p = 0.04 with advanced CKD. With regard to standard drugs in CAD treatment, prescriptions were higher in our registry than in previous reports, but beta-blockers (p = 0.008, and angiotensin-converting-enzyme inhibitors and/or angiotensin-receptor blockers (p<0.001 were given less often in higher CKD stages. In contrast, in the subgroup of patients with moderately to severely reduced LVEF the prescription rates did not differ between CKD stages. In-hospital mortality increased stepwise with each CKD stage (p = 0.02.In line with other studies comprising CKD cohorts, patients' morbidity and in-hospital mortality increased with the degree of renal impairment.

    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.

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 (pdisease management in an "all-comers" patient population undergoing TAVI demonstrates that whilst often an indicator of significant underlying comorbidity coronary artery disease is not associated with decreased short or long-term survival. The majority of patients with aortic stenosis and concomitant CAD can be managed effectively by TAVI alone. However, the importance of the Heart Team in making decisions on individual patients must not be underestimated. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Device entrapment is a rare complication of percutaneous coronary intervention. It has hazardous potentials for the patient. Emergent cardiac surgery is the only option after failure of retrieval devices. We have described here a case of a 55 years old male. During percutaneous coronary intervention, the balloon inflated only partially at its ends and entrapped in the lesion along with the stent. Multiple attempts at inflation failed and the patient developed severe chest pain for few minutes. Surgery was contemplated but final attempt at inflation was successful and the patient stabilized. It was an emergent situation and could have led to fatal outcome, although this patient escaped narrowly from any fatal outcome.

    Thirteen years have passed since the first percutaneous coronary intervention was performed at Onze Lieve Vrouwe Gasthuis in Amsterdam using the transradial approach (TRA). Since then TRA has spread through the interventional community and many centres have now adopted TRA as the arterial access of choice. This review is focused on the hot issues and the latest developments in this field. The following subjects will be addressed and discussed: drawbacks and learning curve, procedural technique, indications (with particular attention to acute coronary patients), complications, contraindications, nurse workload, patient management, and economics.

    The duration of dual antiplatelet therapy (DAPT) after drug-eluting stent implantation in coronary chronic total occlusion (CTO) remains unclear. We retrospectively analyzed a total of 512 patients treated with percutaneous coronary intervention (PCI) in the Samsung Medical Center CTO registry. Patients were separated into ≤ 12-month (199, 38.9%) vs. > 12 month (313, 61.1%) based on DAPT duration with aspirin and clopidogrel. The primary outcome was major adverse cardiac and cerebrovascular event (MACCE) during follow-up. Median follow-up duration was 67 (interquartile range: 51-84) months. MACCE occurred in 43 patients (21.6%) in the ≤ 12-month and 55 patients (17.6%) in the > 12-month groups. In the propensity-matched population, the rate of MACCE did not differ significantly between the ≤ 12-month and > 12-month group (19.4% vs. 18.8%; hazard ratio [HR], 0.95; 95% confidential interval [CI], 0.52-1.76, p = 0.88). Moreover, moderate or severe bleeding according to BARC criteria (type 2, 3 or 5) was also similar between the ≤ 12-month and > 12-month group (2.5% vs. 1.9%; HR, 1.00; 95% CI, 0.20-4.96, p = 0.99). Among patients treated with PCI for CTO, DAPT with durations of ≤ 12-month showed similar long-term clinical outcomes compared to > 12-month DAPT.

    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.

    Full Text Available Introduction. Dislodgement and embolization of the new generation of coronary stents before their deployment are rare but could constitute a very serious complication. Case Outline. We report a case of a stent dislodgement into the left main coronary artery during the primary coronary intervention of infarct related left circumflex artery in a patient with acute myocardial infarction. The dislodged and unexpanded bare-metal stent FlexMaster 3.0x19 mm (Abbot Vascular was stranded and bended in the left main coronary artery (LMCA, probably by the tip of the guiding catheter, but stayed over the guidewire. It was successfully retrieved using a low-profile Ryujin 1.25x15 balloon catheter (Terumo that was passed through the stent, inflated and then pulled back into the guiding catheter. After that, the whole system was withdrawn through the 6 F arterial sheath via the transfemoral approach. After repeated cannulation via the 6F arterial sheath, additional BMW and ATW guidewires were introduced into the posterolateral and obtuse marginal branches and a bare-metal stent Driver (Medtronic Cardiovascular Inc 3.0x18 mm was implanted in the target lesion. Conclusion. Stent dislodgement is a rare but potentially life-threatening complication of the percutaneous coronary intervention. This incident occurring in the LMCA in particular during an acute myocardial infarction requires to be urgently resolved. The avoidance of rough manipulation with the guiding catheter and delivery system may help in preventing this kind of complications.

    We investigated the impact of diabetes mellitus on long-term outcomes of percutaneous coronary intervention (PCI) in the drug-eluting stent era versus coronary artery bypass grafting (CABG) in a real-world population with advanced coronary disease. We identified 3,982 patients with 3-vessel and/or left main disease of 15,939 patients with first coronary revascularization enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto PCI/CABG Registry Cohort-2 (patients without diabetes: n = 1,984 [PCI: n = 1,123 and CABG: n = 861], and patients with diabetes: n = 1,998 [PCI: n = 1,065 and CABG: n = 933]). Cumulative 5-year incidence of all-cause death after PCI was significantly higher than after CABG both in patients without and with diabetes (19.8% vs 16.2%, p = 0.01, and 22.9% vs 19.0%, p = 0.046, respectively). After adjusting confounders, the excess mortality risk of PCI relative to CABG was no longer significant (hazard ratio [HR] 1.16; 95% confidence interval [CI] 0.88 to 1.54; p = 0.29) in patients without diabetes, whereas it remained significant (HR 1.31; 95% CI 1.01 to 1.70; p = 0.04) in patients with diabetes. The excess adjusted risks of PCI relative to CABG for cardiac death, myocardial infarction (MI), and any coronary revascularization were significant in both patients without (HR 1.59, 95% CI 1.01 to 2.51, p = 0.047; HR 2.16, 95% CI 1.20 to 3.87, p = 0.01; and HR 3.30, 95% CI 2.55 to 4.25, p <0.001, respectively) and with diabetes (HR 1.45, 95% CI 1.00 to 2.51, p = 0.047; HR 2.31, 95% CI 1.31 to 4.08, p = 0.004; and HR 3.70, 95% CI 2.91 to 4.69, p <0.001, respectively). There was no interaction between diabetic status and the effect of PCI relative to CABG for all-cause death, cardiac death, MI, and any revascularization. In conclusion, in both patients without and with diabetes with 3-vessel and/or left main disease, CABG compared with PCI was associated with better 5-year outcomes in terms of cardiac death, MI, and any coronary

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

    Directory of Open Access Journals (Sweden)

    Akira Sato

    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.

    Percutaneous coronary intervention (PCI) in an anomalous right coronary artery (RCA) can be technically difficult because selective cannulation of the vessel may not be easy. We thereby present two cases with unstable angina pectoris of anomalous originated RCA. The PCI were successfully performed in two patients with a special guiding wire manipulating skill which we called "gone with the flow" combined with balloon anchoring technology, providing excellent angiographic visualization and sound guide support for stent delivery throughout the procedure without severe cardiovascular adverse effects. Our primary data suggested that PCI for geriatric patients with an anomalous origin of RCA accompanied by severe atherosclerotic lesions might also be a safe, available, and feasible strategy.

    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.

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

    Objective To determine whether the instantaneous wave-free ratio (iFR) can detect improvement in stenosis significance after percutaneous coronary intervention (PCI) and compare this with fractional flow reserve (FFR) and whole cycle Pd/Pa. Design A prospective observational study was undertaken in elective patients scheduled for PCI with FFR ≤0.80. Intracoronary pressures were measured at rest and during adenosine-mediated vasodilatation, before and after PCI. iFR, Pd/Pa and FFR values were calculated using the validated fully automated algorithms. Setting Coronary catheter laboratories in two UK centres and one in the USA. Patients 120 coronary stenoses in 112 patients were assessed. The mean age was 63±10 years, while 84% were male; 39% smokers; 33% with diabetes. Mean diameter stenosis was 68±16% by quantitative coronary angiography. Results Pre-PCI, mean FFR was 0.66±0.14, mean iFR was 0.75±0.21 and mean Pd/Pa 0.83±0.16. PCI increased all indices significantly (FFR 0.89±0.07, pcoronary haemodynamics elicited by PCI. FFR and iFR have a significantly larger dynamic range than resting Pd/Pa. iFR might be used to objectively document improvement in coronary haemodynamics following PCI in a similar manner to FFR.

    American College of Cardiology (ACC) guidelines state that percutaneous coronary interventions (PCI) be performed at centers and by operators with high-volume (>400 yearly/center) whose historical and current risk-adjusted outcomes statistics are comparable to those reported in large registries. Tripler Army Medical Center is a low-volume treatment facility but has a geographic need and special mission requirement for providing this service. We computed 30-day incidence of stent thrombosis, need for repeat revascularization, and all-cause mortality for all PCIs performed at Tripler from January 2002 through June 2008. The New York State Registry regression model was selected among 3 risk-adjustment models that we assessed in our patients. This model was used to compute expected mortality rate based on patient risk factors. The 30-day incidence of stent thrombosis and repeat revascularization was also determined, and the long-term incidence of these events was estimated with the Kaplan-Meier method as was survival. For all 546 PCI procedures, 30-day mortality was 1.47%, the incidence of stent thrombosis 2.1%, the incidence of any repeat revascularization 5.1%, and the combined event rate 5.9%. Based on risk factors used in the New York State Registry, our expected mortality was 1.93% and not significantly different from the observed rate. Although survival at 1 and 3 years appeared comparable with benchmarks at 94.6% and 89.3%, as did repeat revascularization rates at 13.0% and 21.4%, the incidence of stent thrombosis was regarded as high whether the definition included possible cases (3.2% and 3.9%) or only those regarded as definite or probable (2.7% and 3.1%). We did not identify any remediable risk factors for stent thrombosis, nor were we able to identify significant differences by year or by operator. However, visual inspection of a plot of deciles of New York State risk of death demonstrated 2 outlier cases among the 8 who died, who could have been considered

  20. Percutaneous coronary interventions and antiplatelet therapy in renal transplant recipients.

    Cardiovascular disease is the leading cause of mortality and morbidity following renal transplantation (RT), accounting for 40-50% of all deaths. After renal transplantation, an adverse cardiovascular event occurs in nearly 40% of patients; given the dialysis vintage and the average wait time, the likelihood of receiving coronary revascularization is very high. There is a significant gap in the literature in terms of the outcomes of prophylactic coronary revascularization in renal transplantation candidates. Current guidelines on myocardial revascularization stipulate that renal transplant patients with significant coronary artery disease (CAD) should not be excluded from the potential benefit of revascularization. Compared with percutaneous coronary intervention (PCI), however, coronary artery bypass grafting is associated with higher early and 30-day mortality. About one-third of renal transplant patients with CAD have to be treated invasively and so PCI is currently the most popular mode of revascularization in these fragile and compromised patients. A newer generation drug-eluting stent (DES) should be preferred over a bare metal stent (BMS) because of its lower risk of restenosis and improved safety concerns (stent thrombosis) compared with first generation DES and BMS. Among DES, despite no significant differences being reported in terms of efficacy, the newer everolimus and zotarolimus eluting stents should be preferred given the possibility of discontinuing, if necessary, dual antiplatelet therapy before 12 months. Since there is a lack of randomized controlled trials, the current guidelines are inadequate to provide a specifically tailored antiplatelet therapeutic approach for renal transplant patients. At present, clopidogrel is the most used agent, confirming its central role in the therapeutic management of renal transplant patients undergoing PCI. While progress in malignancy-related mortality seems a more distant target, a slow but steady reduction in

    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.

    Although underestimated by interventional cardiologists for a long time, radiation exposure of operators and patients is currently a major concern. The objective of the present operator-blinded registry was to compare related-peripheral arterial route radiation exposure of operators. During 420 consecutive coronary angiograms (CAs) and percutaneous coronary interventions (PCIs), four interventional cardiologists were blindly screened. Radiation exposures were assessed using electronic personal dosimeters. Protection of operator was ensured using a lead apron, low leaded flaps, and leaded glass. Radiation exposure of operators was significantly higher using the radial route when compared with the femoral route for both CAs and CAs followed by ad hoc PCIs: 29.0 [1.0-195.0] microSv vs. 13.0 [1.0-164.0] microSv; P < 0.0001 and 69.5 [4.0-531.0] microSv vs. 41.0 [2.0-360.0] microSv; P = 0.018, respectively. Similarly, radiation exposure of patients was significantly higher using the radial route when compared with the femoral route for both CAs and CAs followed by ad hoc PCIs. Moreover, procedural durations and fluoroscopy times were significantly higher throughout the radial route. Although the radial route decreases peripheral arterial complication rates, increased radiation exposure of operators despite extensive use of specific protection devices is currently a growing problem for the interventional cardiologist health. Radial route indication should be promptly reconsidered in the light of the present findings.

    Chronic kidney disease (CKD) and coronary artery disease (CAD) are strongly associated. CAD is the most frequent cause of cardiovascular death in patients with CKD. The prospective observational nationwide multicenter Coronary Artery Disease and REnal Failure (CAD-REF) Registry enrolled 3352 patients with angiographically documented CAD classified according to their baseline estimated glomerular filtration rate (eGFR) into 5 groups according to the K/DOQI-guidelines. Patients were followed for two years. The aim of this study was the analysis of outcome and the identification of risk factors for two-year mortality in patients with both CKD and CAD. With decreasing renal function, patients had more often diabetes mellitus, hypertension, peripheral artery disease, and previous cardiovascular events and interventions. The amount of diseased vessels increased with decreasing renal function. For the whole cohort, two-year mortality was 6.5%. Kaplan-Meier-curves showed highest mortality in patients with CKD stages 4 and 5 (22.4%). In multivariate Cox-regression analyses, significant risk factors for two-year all-cause mortality were lower eGFR, current smoking, left ventricular ejection fraction, diabetes mellitus treated with oral medication or insulin, age, and peripheral artery disease. Coronary status missed the level of statistical significance as a risk factor for mortality in multivariable regression analysis. An eGFR reduction of 10ml/min/1.73m(2) increased the risk of mortality by 19% regardless of other risk factors. Two-year morbidity and mortality increased with the degree of renal impairment. To improve survival of patients with CAD and CKD, nephroprotection is urgently needed especially for patients with atherosclerotic burden. NCT00679419, http://clinicaltrials.gov/.

    The association between aortic valve disease and coronary atherosclerosis is common. In the recent era of transcatheter aortic valve implantation there is little experience with coronary artery intervention after valve implantation. We report a case of a 80-year-old male who underwent successful coronary artery intervention few months after a Medtronic CoreValve System percutaneous implantation for severe aortic valve stenosis. Verification of the position of the used wires (crossing from inside the self expanding frame) is of utmost importance before proceeding to coronary intervention. In this case, crossing the aortic valve, coronary angiography and percutaneous coronary intervention were successfully performed. In conclusion, percutaneous coronary intervention in patients with previous Medtronic CoreValve System implantation is feasible and safe.

    Objective The effect of statins on coronary artery plaque features beyond stenosis severity is not known. Coronary CT angiography (CCTA) is a novel non-invasive method that permits direct visualization of coronary atherosclerotic features, including plaque composition. We evaluated the association of statin use to coronary plaque composition type in patients without known coronary artery disease (CAD) undergoing CCTA. Methods From consecutive individuals, we identified 6673 individuals (2413 on statin therapy and 4260 not on statin therapy) with no known CAD and available statin use status. We studied the relationship between statin use and the presence and extent of specific plaque composition types, which was graded as non-calcified (NCP), mixed (MP), or calcified (CP) plaque. Results The mean age was 59 ± 11 (55% male). Compared to the individuals not taking statins, those taking statins had higher prevalence of risk factors and obstructive CAD. In multivariable analyses, statin use was associated with increased the presence of MP [odds ratio (OR) 1.46, 95% confidence interval (CI) 1.27–1.68), p < 0.001] and CP (OR 1.54, 95% CI 1.36–1.74, p < 0.001), but not NCP (OR 1.11, 95% CI 0.96–1.29, p = 0.1). Further, in multivariable analyses, statin use was associated with increasing numbers of coronary segments possessing MP (OR 1.52, 95% CI 1.34–1.73, p < 0.001) and CP (OR 1.52, 95% CI 1.36–1.70, p < 0.001), but not coronary segments with NCP (OR 1.09, 95% CI 0.94–1.25, p = 0.2). Conclusion Statin use is associated with an increased prevalence and extent of coronary plaques possessing calcium. The longitudinal effect of statins on coronary plaque composition warrants further investigation. PMID:22981406

    Objective This study sought to determine the correlation between baseline cardiac medications and cardiovascular outcomes in patients with obstructive coronary artery disease (CAD) diagnosed by coronary computed tomographic angiography (CCTA). Methods 1637 patients (mean age 64.8 ± 10.2 years, 69.6% male) with obstructive CAD from the CONFIRM (COronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter) registry were followed over the course of three years. Obstructive CAD was defined as a >50% stenosis in an epicardial vessel. Medications analyzed included statins, aspirin, beta-blockers, angiotensin converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARBs). Using Cox proportional-hazards models, we calculated the hazard ratio (HR) with 95% confidence intervals (95% CIs) for incident major adverse cardiovascular events (MACE), defined as death, acute coronary syndrome, or myocardial infarction. Results At the time of CCTA, 59%, 54%, 40%, and 46% of patients were using statins, aspirin, beta-blockers, and ACE inhibitors or ARBs, respectively. Statins were associated with a 43% (95% CI = 0.38-0.87, p=0.008) lower adjusted risk of MACE. Following adjustment, aspirin, beta-blockers, ACE inhibitors and ARBs did not attenuate the risk of MACE. When restricted to patients with multivessel obstructive CAD, only statins were associated with lower risk of MACE. Conclusion In patients with obstructive CAD by CCTA, the baseline use of statins was associated with improved clinical outcomes. Other cardiac medications—including aspirin, beta-blockers, ACE inhibitors, and ARBs—were not associated with reduced risk of MACE. PMID:25479800

    Percutaneous coronary interventions are associated with increased radiation exposure compared to most radiological examinations. This prospective study aimed at (1) measuring entrance doses for all in-room personnel, (2) performing an assessment of patient effective dose and intracoronary doses, (3) investigating the contribution of each projection to kerma-area product (KAP) and irradiation time, (4) comparing results with established DRL values in this clinical setting and (5) estimating the risk for fatal cancer to patients and operators. Measurements were performed during 40 consecutive procedures of coronary angiography (CA), half of which were followed by ad hoc coronary angioplasty (PTCA). KAP measurements were used for patients and thermoluminescent dosimetry for the in-room personnel. The mean KAP value per procedure for CA was 29 +/- 9 Gy cm2. Thirty four per cent of KAP was due to fluoroscopy, whereas the remainder (66%) was due to digital cine. Accordingly, the mean KAP value per PTCA procedure was 75 +/- 30 Gy cm2, and contribution of fluoroscopy is 57%. Effective dose per year was estimated to be 0.04-0.05 mSv y-1 for the primary operator, and 0.03-0.04 mSv y-1 for those assisting. Corresponding measurements for radiographer and nurse were below detectable level, implying minimal radiation hazards for them. Regarding radiation exposure, coronary intervention is considered a quite safe procedure for both patients and personnel in laboratories with modern equipment and experienced operators as long as standard safety precautions are considered. Exposure optimization though should be constantly sought through continuous review of procedures.

    To compare the advantages and disadvantages of emergency percutaneous coronary intervention through the left radial artery with those of emergency percutaneous coronary intervention through the femoral artery. A total of 206 patients with acute myocardial infarction who required emergency percutaneous coronary intervention and were admitted to our hospital between January 2011 and August 2013 were divided into the following two groups: a group that underwent percutaneous coronary intervention through the left radial artery and a group that underwent percutaneous coronary intervention through the femoral artery. The times required for angiographic catheter and guiding catheter placement, the success rate of the procedure and the incidence of vascular complications in the two groups were observed. There was no significant difference in catheter placement time or the ultimate success rate of the procedure between the two groups. However, the left radial artery group showed a significantly lower incidence of vascular complications than the femoral artery group (pEmergency percutaneous coronary intervention through the left radial artery is associated with less vascular complications than emergency percutaneous coronary intervention through the femoral artery and is thus potentially advantageous for patients.

    There is ongoing development of new therapeutic regimens in the use of antithrombotic agents and anticoagulants focussing on acute coronary syndrome (ACS) with an increasing impact on current guidelines over the last years. This was especially accompanied by an increase in innovative percutaneous coronary interventional (PCI) methods in patients with ACS, non-ST-segment elevation myocardial infarction (NSTEMI) or ST-segment elevation myocardial infarction (STEMI) with a need for therapeutics with more sufficient and effective antiplatelet action. On the other hand, newer direct and indirect thrombin inhibitors with primary use in prevention and therapy of thromboembolic events have been shown to have beneficial and even superior effects in ACS with or without PCI. The current review aims to report on the evidence-based use of approved antithrombotic agents and anticoagulants in ACS with special focus on PCI according to the actualized European guidelines.

  17. Meta-analysis of the effect of percutaneous coronary intervention on chronic total coronary occlusions

    Science.gov (United States)

    2014-01-01

    Background and purpose Coronary chronic total occlusion (CTO) is the last stage of coronary artery atherosclerosis. Percutaneous coronary intervention (PCI) is a therapeutic procedure used to recanalize vessels with total occlusion. However, successful recanalization of CTO is still not optimal, and the key influence factors are still uncertainty. Therefore, a scientific evaluation on the effective of PCI for CTO treatment is necessary. Methods Relevant studies of PCI treatment for CTO were examined. Data were extracted and assessed by two independent clinical experts. Embase, PubMed and Medline et al. were used as database. The main research key words include “CTO”, “PCI”, “Stent”, “Reopen”, “long-term”, “follow-up” and “outcome”. Quality assessment was carried out according to the Cochrane Handbook. The selected data were pooled and analyzed using fixed-effect model and random-effect model. Heterogeneity was assessed using the I2 test, Q test, L’abbe and Galbraith. Comprehensive Meta -Analysis 2.0 and Metanalysis 1.0 were used for statistics analysis in this research. Results A total of 16 articles involving 6695 cases in successful CTO recanalization (CTO success group) and 2370 cases in failed CTO recanalization(CTO failure group) were included in this research. Low CTO success was associated with elder age, previous coronary artery bypass graft surgery (CABG) history, multi-vessel diseases and right coronary artery disease lesion. Six follow-up variables including major adverse cardiac events (MACE), recurrent myocardial infarction (MI), all-cause death, incidence of angina, subsequent CABG and cumulative survival rate were found significantly reduced associated with CTO success. Conclusions Clinical baseline characteristics such as age, previous CABG history and lesion baseline characteristics such as lesion length, multi-vessel diseases might be important factors influencing the successful rate of CTO recanalization.

To calculate the mean knowledge score about CAD risk factors among them. A multi center crossectional study was conducted in Universities and colleges of Karachi East from April-September 2005. Questionnaires were distributed to 200 adult students of different non-medical universities and colleges. The questionnaire contained assessment of knowledge of risk factors on CAD and awareness about coronary angiography. Those belonging to medical colleges and universities were excluded from the study. Knowledge was assessed as a continuous variable. Risk factors for CAD were taken as categorical variables The mean age of students was 20 yrs +/- 2.2 years and 62% were females. The mean score of knowledge about risk factors of CAD was 11.47 +/- 2.37. Sixty percent students thought that heart diseases are the number one cause of death in our population. Twenty five percent students graded smoking as the top most risk factor for CAD. Twenty five percent students refused to quit smoking for CAD prevention. Forty eight percent students correctly defined coronary angiography. Eighty five percent students thought that cost is the major hindrance in getting timely treatment. Knowledge of fifty percent students was based on personal and family experience of heart disease. Students graded smoking as the topmost risk factor for CAD and cost as the major hindrance in getting timely treatment for heart disease. Only half of the students were aware about coronary angiography. The mean knowledge score among them was above the median score but not up to the mark.

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.

    2016-01-01

    Background:Angiopoietin-2 (Ang-2) plays a crucial role in hypoxia-induced angiogenesis and is expressed only in sites of vascular remodeling.Ang-2 expression can be regulated by hypoxia inducible factors and other regulators with exposure to hypoxia.The objective of this study was to investigate the influence of percutaneous coronary intervention (PCI) on serum Ang-2 concentrations,and analyze the correlation between serum Ang-2 and the severity of coronary artery stenosis in patients with coronary heart disease (CHD).Methods:Sixty-four patients with CHD were selected as the study group,each undergone PCI.Thirty-two healthy subjects were selected as the control group.Pre-PCI and post-PCI serum Ang-2 were measured by enzyme-linked immunosorbent assay.The severity of coronary artery stenosis was evaluated using angiographic Gensini scores,and the coronary collateral vessels were scored according to Rentrop's classification.Results:Concentrations of pre-PCI serum Ang-2 in the study group were significantly higher than those in the control group (4625.06 ± 1838.06 vs.1945.74 ± 1588.17 pg/ml,P < 0.01);however,concentrations of post-PCI serum Ang-2 were significantly lower than those of pre-PCI (3042.63 ± 1845.33 pg/ml vs.4625.06 ± 1838.06 pg/ml,P < 0.01).Concentrations of pre-PCI serum Ang-2 were significantly correlated with Gensini scores (r =0.488,P < 0.01);however,the decrease in serum Ang-2 after PCI was not correlated with Gensini scores,coronary collateral vessel grading,or left ventricular ejection fraction.Conclusions:Serum Ang-2 concentrations significantly increased in patients with CHD,and PCI treatment significantly decreased these concentrations.Serum Ang-2 concentrations,but not the decrease in serum Ang-2 concentrations,were significantly correlated with the severity of coronary artery stenosis.These results suggested that Ang-2 may be a biomarker of myocardial ischemia and vessel remodeling.

    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.

    Objective To introduce the initial experience of direct pereutaneous transluminalcoronary angioplasty (PTCA) and intracoronary stenting in patients with acute myocardial infarction(AMl) from October t998 to Novermber 200l in our hospital. Methods Primary PTCA was per-formed in 38 patients with acute myocardial infarction. 29 cases were 20 male and 9 female, rangingin age from 30 to 76 old years. 23 cases hvad anterior and 15 lind inferior wall infarction. The patients we chose for direct coronary intervention therapy had stable hemodynamics. Of the 38 infarct re-lated arteries (IRA), 23 were left anterior descend arteries (LAD), 4 left circumflex (LCX) andl 1 right coronary arteries (RCA). 33 IRA were TIMI 0 flow and 5 TIMI 1 flow. The indicationsOf the 38 patients with AMI, PTCA tns successful in 35. Two patients were given up because 014guide-wire entered into false lumen. One was selected for emergency coronary artery bypass graft because of LAD infarct related artery accompanied by 70% stenosis of left main. 35 intracoronarystenls were implanted. 16 patients were followed up, of whom 2 patients trod restenosis and were suc-cessful in the second attempt. Conclusion Direct PTCA and stent implantation are effective andsafe means of treatment for AMI and stent implantation can prevent and cure the arute reocclusion after PTCA.

    The study was aimed to compare the characteristics and inhospital and 12- and 36-month outcomes of men and women <40 years with acute coronary syndrome (ACS). The analysis involved 932 patients <40 years with ACS in the Silesia region enrolled into the ongoing, prospective Polish Registry of Acute Coronary Syndromes from January 2006 to December 2014. The composite end point involved death, recurrence of ACS, a need for percutaneous coronary intervention, and coronary artery bypass graft surgery within 12 and 36 months after ACS. Compared with men, women <40 years were less frequently smokers (66.1% vs 55.4%, p = 0008), had older average age (35.6 ± 4.2 vs 34.7 ± 4.4, p = 0.002), more often had unstable angina at admission (29.1% vs 19.3%, p <0.001), and less frequently had ST-elevation myocardial infarction: 41.3% versus 51.3%, p = 0.02, at admission. There was no significant difference in the mortality (4.8% vs 3.1%, p = 0.29) and the composite end point (21.6% vs 16.0%, p = 0.14) within 12 months after ACS. Compared with men, women had a higher incidence of the composite end point (28.4% vs 20.1%, p = 0.04) and indicated a tendency of a higher mortality within the 36-month follow-up period (9.2% vs 5.0%, p = 0.055). Female gender turned out to be an independent risk factor of death in the multivariate analysis (hazard ratio 2.76, 95% confidence interval 1.21 to 6.31, p <0.016). In conclusion, women had a higher incidence of the composite end point and showed a tendency toward a higher mortality than the men within the 36-month follow-up period.

    The aim of this study was to compare the ability of conventional versus computed tomography angiography (CTA) to predict procedural success and 30-min wire crossing rates in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions. Coronary CTA can be used to assess the morphology of CTO lesions. We examined 205 consecutive patients (218 CTO lesions) who underwent coronary CTA pre-PCI. The J-CTO (Multicenter CTO Registry of Japan) score (the sum of the following 5 binary parameters: blunt proximal cap, calcification, bending >45°, and length of occluded segment >20 mm plus previously failed PCI attempt) was calculated using both CTA and conventional coronary angiography and compared. The median patient age was 69 years (interquartile range: 62 to 75 years), 82.4% were male, and a retrograde approach was attempted in 72 (33.0%) cases. The procedural success rate of the CTO-PCI procedures was 82.6%, and 29.4% of cases achieved 30-min wire crossing. The areas under the curve of the CTA-derived J-CTO score for predicting procedural success and 30-min wire crossing were significantly greater than those derived from conventional angiography (0.855 vs. 0.698; p CTO score was a more useful predictor of both procedural success and 30-min wire crossing than the J-CTO score derived from conventional angiography.

    To identify factors associated with right ventricular (RV) dilatation in patients with coronary heart disease (CHD) without prior myocardial infarction (Ml). Out of 16 839 patents from the Coronary Angiography Surgery Registry, the investigators selected patients with >75% stenosis in at least one coronary artery without acute or prior MI: 75 patients with echocardiographically detected RV dilatation and 1134 without RV dilatation. Among the patients with RV dilatation, there were more men (92% versus 80.2%; p=0.01 2). In this group, the mean body mass index (BMI) was higher (31.7±5.2 kg/m2 versus 30.1±4.7 kg/m2; p=0.01 9); there was more commonly higher NYHA functional class (FC) (III) chronic heart failure (CHF) (22.2% versus 12.5%; p=0.002), clinically relevant mitral regurgitation (29.4% versus 4.0%; all ps<0.001), and cardiac rhythm and conduction disturbances (45.5% versus 17.8%; p<0.001) in rarer severe FC (III-IV) exertional angina (30.3% versus 52.8%; p=0.007). The groups were different as evidenced by coronarography and major blood biochemical indicators. Decreased myocardial contractility (odds ratio (OR), 4.22; p=0.002), male sex (OR, 4.03;p=0.007), cardiac rhythm and conduction disturbances (OR, 2.98; p<0.001), clinically relevant mitral regurgitation (OR, 2.34; p=0.001); higher FC CHF (OR, 1.87; p=0.034), BMI (OR, 1.08; p=0.01 0), and lower FC exertional angina (OR, 0.42; p=0.001) demonstrated an independent relationship to RV dilatation, as evidenced by a multivariateanalysis. In the patients with CHD without MI, RV dilatation is independently related to male sex, left ventricular functional characteristics, and higher BMI.

    The aim of the present study was to define the feasibility and clinical impact of complying with national consensus recommendations on perioperative management of antiplatelet therapy in patients with coronary stents undergoing cardiac and noncardiac surgery. There are limited evidence-based recommendations on the perioperative management of antiplatelet therapy in stented patients undergoing surgery. The recommendations provided by the national consensus document were applied in a multicenter, prospective registry of consecutive patients with prior coronary stenting undergoing any type of surgery at 19 hospitals in Italy. The primary end-point was in-hospital net adverse clinical events (NACE) represented by the composite of all-cause death, myocardial infarction, probable/definite stent thrombosis and Bleeding Academic Research Consortium (BARC) grade ≥3 bleeding. Patients were followed for 30 days. A total of 1,082 patients were enrolled. Adherence to consensus recommendations occurred in 85% of the cases. Perioperative aspirin and dual antiplatelet therapy were maintained in 69.7 and 10.5% of the cases, respectively. In-hospital NACE rate was 12.7%, being significantly higher in patients undergoing cardiac surgery (36.3% vs. 7.3%, P antiplatelet therapy in stented patients undergoing surgery. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Coronary artery disease (CAD) is the most prevalent form of cardiovascular disease affecting about 13 million Americans, while more than one million percutaneous transluminal intervention (PCI) procedures are performed annually in the USA. The relative high occurrence of restenosis, despite stent implementation, seems to be the primary limitation of PCI. Over the last decades, single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI), has proven an invaluable tool for the diagnosis of CAD and patients' risk stratification, providing useful information regarding the decision about revascularization and is well suited to assess patients after intervention. Information gained from post-intervention MPI is crucial to differentiate patients with angina from those with exo-cardiac chest pain syndromes, to assess peri-intervention myocardial damage, to predict-detect restenosis after PCI, to detect CAD progression in non-revascularized vessels, to evaluate the effects of intervention if required for occupational reasons and to evaluate patients' long-term prognosis. On the other hand, chest pain and exercise electrocardiography are largely unhelpful in identifying patients at risk after PCI.Although there are enough published data demonstrating the value of myocardial perfusion SPECT imaging in patients after PCI, there is still debate on whether or not these tests should be performed routinely.

    Full Text Available Abstract Background: Obstructive sleep apnea (OSA is a very often clinical condition that can be associated with high mortality risk, particularly in coronary heart disease (CHD. The diagnosis of OSA is not always accessible via the gold-standard method polysomnography. Objective: To evaluate long-term influence of the high risk for OSA on fatal and non-fatal outcomes after acute coronary syndrome (ACS in the Acute Coronary Syndrome Registry Strategy (ERICO Study using the Berlin questionnaire as a surrogate. Methods: Berlin questionnaire, a screening questionnaire for OSA, was applied in 639 cases of ACS 30 days after the index event. Cox regression proportional-hazards model was used to calculate the hazard ratio (HR of all-cause, cardiovascular and CHD (myocardial infarction mortality, as well as, the combined endpoint of fatal or recurrent non-fatal CHD. Results: The high-risk group for OSA had higher frequencies of previous personal/family history of CHD and diabetes, in addition to a poorer event-free survival, as compared to the low-risk group (p-log-rank=0.03. The HR for fatal or recurrent non-fatal CHD was 4.26 (95% confidence interval, 1.18 - 15.36 in patients at high risk for OSA compared to those at low risk for OSA after a 2.6-year mean follow-up. Conclusions: Using Berlin questionnaire, we were able to identify high risk for OSA as an independent predictor of non-fatal reinfarction or CHD mortality in post-ACS individuals in a long-term follow-up.

    Background 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. Methods and Results 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. Conclusion 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. PMID:27314589

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.

    Objective 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 and setting Patients with NSTEACS (n  =  1877) admitted to 45 randomly selected Spanish hospitals in April and May 2002 were studied. Design Patients with ST segment depression and troponin rise were considered high risk (n  =  478) and were compared with non‐high risk patients (n  =  1399). Results 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 < 0.001) were given glycoprotein IIb/IIIa inhibitor. In‐hospital and six‐month mortality were 7.5% versus 1.1% and 17% versus 4.6% (p < 0.001), respectively. A treatment score (⩾ 4, 2–3 and < 2) was defined according to the number of class I interventions recommended in clinical guidelines: aspirin, clopidogrel, β blockers, angiotensin‐converting enzyme inhibitors, statins and revascularisation. Independent predictors of six‐month mortality were age (odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04 to 1.10, p < 0.001), diabetes (OR 1.92, 95% CI 1.14 to 3.22, p  =  0.014), previous cardiovascular disease (OR 4.17, 95% CI 1.63 to 10.68, p  =  0.003), high risk (OR 2.20, 95% CI 1.30 to 3.71, p  =  0.003) and treatment score < 2 versus ⩾ 4 (OR 2.87, 95% CI 1.27 to 6.52, p  =  0.012). Conclusions 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. PMID:16644860

    Full Text Available Abstract Background While prior research has provided important information about readmission rates following percutaneous coronary intervention, reports regarding charges and length of stay for readmission beyond 30 days post-discharge for patients in a large cohort are limited. The objective of this study was to characterize the rehospitalization of patients with acute coronary syndrome receiving percutaneous coronary intervention in a U.S. health benefit plan. Methods This study retrospectively analyzed administrative claims data from a large US managed care plan at index hospitalization, 30-days, and 31-days to 15-months rehospitalization. A valid Diagnosis Related Group code (version 24 associated with a PCI claim (codes 00.66, 36.0X, 929.73, 929.75, 929.78–929.82, 929.84, 929.95/6, and G0290/1 was required to be included in the study. Patients were also required to have an ACS diagnosis on the day of admission or within 30 days prior to the index PCI. ACS diagnoses were classified by the International Statistical Classification of Disease 9 (ICD-9-CM codes 410.xx or 411.11. Patients with a history of transient ischemic attack or stroke were excluded from the study because of the focus only on ACS-PCI patients. A clopidogrel prescription claim was required within 60 days after hospitalization. Results Of the 6,687 ACS-PCI patients included in the study, 5,174 (77.4% were male, 5,587 (83.6% were Conclusions For ACS patients who underwent PCI, revascularization procedures represented a large portion of rehospitalizations. Revascularization procedures appear to be the most frequent, most costly, and earliest cause for rehospitalization after ACS-PCI.

  19. Serum biomarkers and source of inflammation in acute coronary syndromes and percutaneous coronary interventions.

    There is robust information that confirms the enormous contribution of inflammation to plaque development, progression and vulnerability. The presence of plaques with inflammatory components associates with a greater likelihood of future cardiovascular events. The inflammatory cascade has been implicated during the entire plaque formation, from the early stages of endothelial dysfunction to the development of acute coronary syndromes (ACS). The presence of macrophages, T lymphocytes, dendritic cells, and mast cells in atherosclerotic lesions; the detection of HLA class II antigen expression; and the finding of secretion of several cytokines point to the involvement of immune inflammatory mechanisms in the pathogenesis of atherosclerosis. Serum biomarkers reflecting the activity of biological processes involved in plaque growth or destabilization may provide great help in establishing the appropriate clinical management, and therapeutic interventions. Evidence for a role of inflammation in plaque rupture has been demonstrated by localization of inflammation at plaque rupture sites. However, the focus of inflammation may not precisely reside within the coronary vessel itself but rather in the injured myocardium distal to the disrupted plaque. These observations outline the potential benefits of therapies targeting inflammation in the arterial wall and cardiovascular system. Emerging anti-inflammatory approaches to vascular protection have the potential to benefit patients by marked reductions in serum biomarkers of inflammation and reduce vascular events. With ongoing technical advances, percutaneous coronary interventions (PCI) will continue to play a critical role in the evaluation of novel compounds designed to modulate inflammation. The constant refinements in the different therapeutic strategies, the combination of scientific understanding in the adequate utilization of novel inflammatory markers, the new pharmacologic agents, and the new techniques in PCI will

    It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS). Fifteen patients older than 65 years with ACS within 24 hours of the event were admitted from April 4, 2004 to December 12, 2005. All the patients had early percutaneous coronary intervention and were followed up for 6-12 months by telephone or in the out-patient department. Nine of the 15 patients exhibited acute myocardial infarction (AMI). Six exhib-ited unstable angina (UA). All the patients had early PCI. The average door-to-balloon time was 78 minutes (40-110 minutes). The average PCI time was 99 minutes (68-120 minutes). Nineteen of 36 lesions in the fifteen angioplasty patients were treated and 20 stents were implanted in total. All the procedures were considered successful. Neither deaths nor recurrent angina occurred in the 6-12 months of follow-up. It was shown that early PCI might be an effective and safe method to treat eld-erly patients with ACS.

    Full Text Available Lifestyle diseases particularly coronary artery disease (CAD has been noted to be the most important   cause of the morbidity and mortality all over the world.  India is currently passing through this epidemic so much  so that it would be taking a heavy toll of Indian youth and economy to the tune of some 1.6 trillion $ during 2015-2030 . The main causative factors for CAD identified as coronary risk factors are: smoking / tobacco, physical inactivity, faulty diet, hypertension, diabetes, high level of cholesterol and stress. As most of these risk factors are lifestyle related attempt to modify them by appropriate interventions form the cornerstone of prevention of CAD epidemic.  Studies done by Dean Ornish and several others prompted us to plan an interventional case control study in 640 patients of established CAD. These cases were given power point presentation regarding healthy lifestyle on one to one basis and followed up at three and six months. Primary outcomes variable were change in smoking /tobacco habits, physical activity, obesity, dietary habits, control of hypertension, diabetes and lipid profile.  At the end of intervention it was possible to bring down the tobacco consumption, improve physical activity, better control of hypertension ( p< 0.03 , reduction in obesity ( p= 0. 0005 and raising HDL cholesterol ( p 0.05 significantly in test group.  Taking cue from above study a five step innovative strategy was developed for effective implementation of healthy life style in coronary patients attending Cardiac Clinic at HAH Centenary Hospital, Jamia Hamdard. This strategy  included sensitizing patients to  locally developed visuals , posters and pamphlets at  registration desk , concurrent counseling by attending doctor  at the end of clinical examination ,  and showing patients  and their  family the features of atherosclerosis during  carotid  ultrasound assessment . These points were again reinforced at follow up

    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

    Percutaneous coronary intervention (PCI) has been extensively applied to repair the forward flow of diseased coronary artery and can achieve significant curative results. However, some patients with acute myocardial infarction (AMI) develop non-perfusion or poor perfusion of cardiac muscle tissue after PCI, which increases the incidence of cardiovascular events and the death rate. PCI can dredge narrowed or infarct-related artery (IRA) and thus induce full reperfusion of ischemic myocardium. It is found in practice that some cases of AMI still have no perfusion or poor perfusion in myocardial tissue even though coronary angiography suggests opened coronary artery after PCI, which increases the incidence of vascular events and mortality. Therefore, to explore the detailed mechanism of PCI in treating coronary microcirculation of patients with stable angina pectoris, we selected 140 patients with stable angina pectoris for PCI, observing the index of microcirculatory resistance (IMR) of descending branch and changes of myocardial injury markers and left ventricular systolic function, and made a subgroup analysis based on the correlation between clinical indexes, IMR and other variables of diabetic and non-diabetic patients, PCI-related and non-PCI-related myocardial infarction patients. The results suggest that IMR of anterior descending branch after PCI was higher compared to that before PCI, and the difference was significant (P less than 0.05); creatine kinase-MB (CK-MB), myohemoglobin and high sensitive troponin T were all increased after PCI, and the difference was also significant (P less than 0.05); brain natriuretic peptide (BNP) level became higher after PCI, with significant difference (P less than 0.05); left ventricular ejection fraction (LVEF) declined after PCI, and the difference before and after PCI was statistically significant (P less than 0.05). Moreover, subgroup analysis results of the three groups all demonstrated statistically significant

However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI, has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical

    The introduction of the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score has prompted a renewed interest for angiographic risk stratification in patients undergoing percutaneous coronary intervention. Syntax score is based on qualitative and quantitative characterization of coronary artery disease by including 11 angiographic variables that take into consideration lesion location and characteristics. Thus far, this score has been shown to be an effective tool to risk-stratify patients with complex coronary artery disease undergoing percutaneous coronary intervention in the landmark SYNTAX trial, as well as in other clinical settings. This review provides an overview of its current applications, including its integration with other nonangiographic clinical scores, and explores future applications of the SYNTAX and derived scores.

    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 Relation of antiplatelet therapy (APT discontinuation with the risk of serious cardiovascular events has not been fully addressed yet. This study is aimed to evaluate the risk of ischemic event after APT discontinuation based on long-term APT status of large cohort. In the CREDO-Kyoto Registry Cohort-2 enrolling 15939 consecutive patients undergoing first coronary revascularization, 10470 patients underwent percutaneous coronary intervention either with bare-metal stents (BMS only (N=5392 or sirolimus-eluting stents (SES only (N=5078. Proportions of patients taking dual-APT were 67.3% versus 33.4% at 1-year, and 48.7% versus 24.3% at 5-year in the SES and BMS strata, respectively. We evaluated daily APT status (dual-, single- and no-APT and linked the adverse events to the APT status just 1-day before the events. No-APT as compared with dual- or single-APT was associated with significantly higher risk for stent thrombosis (ST beyond 1-month after SES implantation (cumulative incidence rates beyond 1-month: 1.23 versus 0.15/0.29, P<0.001/P<0.001, while higher risk of no-APT for ST was evident only until 6-month after BMS implantation (incidence rates between 1- and 6-month: 8.43 versus 0.71/1.20, P<0.001/P<0.001, and cumulative incidence rates beyond 6-month: 0.31 versus 0.11/0.08, P=0.16/P=0.08. No-APT as compared with dual- or single-APT was also associated with significantly higher risk for spontaneous myocardial infarction (MI and stroke regardless of the types of stents implanted. Single-APT as compared with dual-APT was not associated with higher risk for serious adverse events, except for the marginally higher risk for ST in the SES stratum. In conclusion, discontinuation of both aspirin and thienopyridines was associated with increased risk for serious cardiovascular events including ST, spontaneous MI and stroke beyond 1-month after coronary stenting.

    The decision on whether to implant a drug-eluting or bare-metal stent during percutaneous coronary intervention (PCI) depends in part on the perceived likelihood of the patient developing late stent thrombosis. Noncardiac surgery and bleeding are associated with discontinuation of dual antiplatelet therapy and with increased stent thrombosis. We assessed the incidence of and predictors for subsequent noncardiac surgery and bleeding episodes in patients who had undergone PCI. Hospital discharge coding data were used to identify all adult patients undergoing public hospital PCI in New Zealand from 1996 to 2001. Hospital admissions during the ensuing 5 years were analyzed for noncardiac surgery and bleeding episodes. Eleven thousand one hundred fifty-one patients (age, 62+/-11 years; 30% women) underwent PCI, mainly for an acute coronary syndrome (73%). During the 5-year follow-up, 26% of the population underwent at least 1 noncardiac surgical procedure (23% orthopedic, 20% abdominal, 12% urologic, 10% vascular, 35% others) and 8.6% had at least 1 bleeding episode either requiring or occurring during hospitalization. Of those, half were gastrointestinal, and one quarter of bleeding events required blood transfusion. The main clinical predictors of noncardiac surgery were advanced age, previous noncardiac surgery, osteoarthritis, and peripheral vascular disease. A previous bleeding admission and age were the strongest predictors of subsequent bleeding. Noncardiac surgery is required frequently after PCI, whereas bleeding is less common. Before implanting a drug-eluting or bare-metal stent, individual patient risk stratification by the interventional cardiologist should include assessment of whether there is an increased likelihood of needing noncardiac surgery or developing bleeding.

    Full Text Available The treatment of choice between coronary artery bypass graft surgery (CABG and percutaneous coronary intervention (PCI has remained unclear. Considering quality of life (QOL increases life expectancy, we believe QOL should be important in determining the optimum treatment. Thus the objective of this review was to illustrate the comparative effects of CABG and PCI on postprocedural QOL. Methods. We searched PubMed (Medline and Embase from inception of the databases to May 2014 using “PCI versus CABG quality of life”, “Percutaneous Coronary intervention versus Coronary artery bypass graft surgery Quality of life”, “PCI versus CABG health status”, “Angioplasty versus CABG”, “Percutaneous coronary intervention versus coronary artery bypass surgery health status”, and different combinations of the above terms. 447 articles were found. After applying strict exclusion criteria, we included 13 studies in this review. Results. From the 9 studies that compared QOL scores at 6 months after procedure, 5 studies reported CABG to be superior. From the 10 studies that compared QOL among patients at 1 year after procedure, 9 reported CABG to be superior. Conclusion. It can be established that CABG is superior to PCI in improving patient’s QOL with respect to all scales used to determine quality of life.

    This study investigated the impact of final kissing ballooning (FKB) after main vessel (MV) stenting on outcomes in patients with coronary bifurcation lesions after application of the 1-stent technique. Although FKB has been established as the standard method for bifurcation lesions treated with a 2-stent strategy, its efficacy in a 1-stent approach is highly controversial. This study enrolled 1,901 patients with a bifurcation lesion with a side branch diameter ≥2.3 mm, treated solely with the 1-stent technique using a drug-eluting stent from 18 centers in Korea between January 1, 2003 and December 31, 2009. The primary outcome was major adverse cardiac events (MACE)-cardiac death, myocardial infarction, or target lesion revascularization. Propensity score-matching analysis was also performed. FKB was performed in 620 patients and the post minimal lumen diameter of the MV and side branch was larger in the FKB group than in the non-FKB group. During follow-up (median 36 months), the incidence of MACE (adjusted hazard ratio [HR]: 0.68, 95% confidence interval [CI]: 0.46 to 0.99; p = 0.048) was lower in the FKB group than the non-FKB group. After propensity score matching (545 pairs), the FKB group had a lower incidence of MACE (adjusted HR: 0.50, 95% CI: 0.30 to 0.85; p = 0.01), and target lesion revascularization in the MV (adjusted HR: 0.51, 95% CI: 0.28 to 0.93; p = 0.03) and both vessels (adjusted HR: 0.47, 95% CI: 0.25 to 0.90; p = 0.02) than in the non-FKB group. In coronary bifurcation lesions, we demonstrated that the 1-stent technique with FKB was associated with a favorable long-term clinical outcome, mainly driven by the reduction of target lesion revascularization in the MV or both vessels as a result of an increase in minimal lumen diameter.

We sought to study the prevalence and coexistence of 6 cardiovascular risk factors (RFs among patients who underwent percutaneous coronary intervention (PCI, and to evaluate the impact of age and gender on the presence of multiple RFs. Methods and results. In this prospective, multicenter study, 2426 consecutive patients were enrolled. Mean age was 59.0 ± 10.1 years and 500 (20.6% were women. Acute coronary syndrome and stable coronary disease were the indications for PCI in 77.1% and 22.9%, respectively. Hypertension was present in 62.3%, diabetes in 53.8%, hypercholesterolemia in 48.8%, smoking in 43.5%, family history of premature CVD 39.4% and obesity in 28.8%. Only 3.8% did not have any of these RFs. Presence of ⩾3 and ⩾4 RFS was observed in 57.4% and 29.5% of patients, respectively. Presence of ⩾3 RFs was more common in women than men (69.0% vs. 54.5%, p < 0.0001, and among patients 41–65 years of age than older or younger patients (60.1% vs. 52.0% vs. 48.3%, respectively, p = 0.017. Conclusions: Cardiovascular RFs are highly prevalent in this PCI Middle Eastern population undergoing PCI. More than half and more than one-fourth of the patients had at least 3 or 4 RFs; respectively. More women than men and more middle aged patients than older or younger patients had significantly higher rates of presence of multiple RFs.

    Full Text Available Purpose: Obesity is a well-known risk factor for adverse cardiovascular events, but some studies suggest higher body mass index (BMI is associated with better outcomes after ST-segment elevation myocardial infarction (STEMI. We sought to determine the effect of body surface area (BSA on adverse events after primary percutaneous coronary intervention (PCI for STEMI and how this relates to the reported obesity paradox theory. Methods: We analyzed a prospective registry of patients with STEMI who underwent primary PCI at a tertiary care hospital from 2003 to 2009. Post-PCI complications and 1-year all-cause mortality were compared across BSA quartiles. Relationship with 1-year mortality was compared between BSA and BMI using logistic regression. Results: Of 2,195 study patients (31.5% women, mean BSA and BMI were 2.0 ± 0.3 m2 and 29.2 ± 6.2 kg/m2, respectively. The 1-year all-cause mortality from the lowest to highest quartiles of BSA was 11.0%, 6.5%, 5.5% and 5.1%, Ptrend<0.0001. Over a mean 5-year follow-up, there was a 76% relative risk reduction in death for each 1 m2 increase in BSA. Higher BSA was associated with lower incidence of cardiogenic shock, acute renal failure, coronary dissection and vascular and bleeding complications post-PCI. In multivariate analysis, BSA remained strongly predictive of 1-year mortality (odds ratio 0.4 per m2 of BSA, 95% confidence interval 0.15–0.9, but BMI showed no independent association with mortality (odds ratio 0.99, 95% confidence interval 0.95–1.04. Conclusions: In STEMI patients undergoing primary PCI, high BSA is associated with lower mortality and complication rates. BMI is not independently associated with 1-year mortality after adjusting for BSA and sex.

    Background Many studies have examined gender related differences in the presenting symptoms, management and prognosis of patients with acute coronary syndrome (ACS). Much data are available from industrialized countries, in which ACS is a major cause of morbidity and mortality, but relatively little information has been obtained from China,where an epidemic of cardiovascular disease is starting to emerge. The purpose of this study was to assess the differences in clinical practice in a national Chinese sample.Methods A total of 12 medical teaching hospitals participated in CRACE. Data collection began in 2001 and continued until 2004, 1301 patients with ACS were enrolled into the study. We compared the clinical demographics, different therapies and outcomes in hospitals between female and male patients with ACS.Results Patients had an average age of 63.13 years (ranging from 27 to 93 years) and 318 female and 983 male subjects were enrolled. Female subjects were older than male patients (67.23 years vs 61.80 years, P<0.0001). The incidence of angina, heart failure, diabetes mellitus and hypertension in the female group was higher than in male group(73.6% vs 62.3%, P<0.0001; 8.2% vs 5.7%, P=0.031; 30.8% vs 18.6%, P<0.0001 and 66.4% vs 56.8%, P=0.001 respectively), but the incidence of smoking was less in the female group than in the male group (6.6% vs 66.2%,P<0.0001). More male patients presented with ST-segment elevation myocardial infarction (STEMI) compared with female patients (48.5% vs 39%, P=0.002). With the exception of β-blocker administration, no differences were found among medications including aspirin, ACEI, lipid lowering agents and low-molecular-weight heparin (LMWH) between female and male patients presenting with ACS in hospitals. Compared with male patients with non-ST-segment elevation(NSTE) ACS, female subjects were more prone to receive β-blockers (75.1% vs 63.4%, P=0.001). Among STEMI and NSTE-ACS patients, fewer female subjects

    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.

    Background The clinical significance of complete revascularization for ST segment elevation myocardial infarction (STEMI) pa-tients during admission is still debatable. Methods A total of 1406 STEMI patients from the Korean Myocardial Infarction Registry with multivessel diseases without cardiogenic shock who underwent primary percutaneous coronary intervention (PPCI) were analyzed. We used propensity score matching (PSM) to control differences of baseline characteristics between culprit only intervention (CP) and multivessel percutaneous coronary interventions (MP), and between double vessel disease (DVD) and triple vessel disease (TVD). The major adverse cardiac event (MACE) was analyzed for one year after discharge. Results TVD patients showed higher incidence of MACE (14.2%vs. 8.6%, P=0.01), any cause of revascularization (10.6%vs. 5.9%, P=0.01), and repeated PCI (9.5%vs. 5.7%, P=0.02), as compared to DVD patients during one year after discharge. MP reduced MACE effectively (7.3%vs. 13.8%, P=0.03), as compared to CP for one year, but all cause of death (1.6%vs. 3.2%, P=0.38), MI (0.4%vs. 0.8%, P=1.00), and any cause of revascularization (5.3%vs. 9.7%, P=0.09) were comparable in the two treatment groups. Conclusions STEMI patients with TVD showed higher rate of MACE, as compared to DVD. MP performed during PPCI or ad hoc during admission for STEMI patients without cardiogenic shock showed lower rate of MACE in this large scaled database. Therefore, MP could be considered as an effective treatment option for STEMI patients without cardiogenic shock.

    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

    An annual survey on cardiac interventions in Europe is performed by the working group on Coronary Circulation of the European Society of Cardiology with the help of the national societies of cardiology. A questionnaire about cardiac interventions in 1993 was mailed to a representative of the national societies of 35 members of the European Society of Cardiology. The data collection of coronary interventions was delayed by slow backreporting and from 10 of the 35 national members data were missing or grossly incomplete. They were excluded from the analysis. A total of 756,822 coronary angiograms were reported resulting in an incidence of 1146 +/- 1024 per 10(6) inhabitants, ranging from 24 (Romania) to 3499 (Germany). This represents an increase of 12% compared to 1992. Germany (279,882 cases), France (157,237), the United Kingdom (77,000), Italy (44,934) and Spain (37,591) registered 79% of all the coronary angiograms performed. A total of 183,728 percutaneous transluminal coronary angioplasty cases were reported in 1993, 24% more than in 1992. On average, they accounted for 18 +/- 7% (range 8 (Romania) to 35% (Sweden) of the coronary angiograms. Most of these percutaneous transluminal coronary angioplasties (82%) were confined to a single vessel. In 13% only, percutaneous transluminal coronary angioplasty took place immediately after the diagnostic study. Adjusted per capita. Germany ranks first with 873 percutaneous transluminal coronary angioplasties per 10(6) inhabitants, followed by France (737), Holland (725), Belgium (713), and Switzerland (665). The European mean of percutaneous transluminal coronary angioplasties per 10(6) inhabitants was 270 +/- 279, representing an increase of 14% compared with 1992. A major in-hospital complication was reported in 3.8% of the patients undergoing percutaneous transluminal coronary angioplasty: 0.6% hospital deaths, 1.5% emergency coronary artery bypass grafting, and 1.7% myocardial infarctions. In 1993 stents were

    Clinical heart failure (HF) occurs frequently after ST-segment elevation myocardial infarction (STEMI), and is associated with increased mortality. We assessed the impact of remote ischemic peri-conditioning (RIPC) during inter-facility air medical transport of STEMI patients on clinical HF following primary percutaneous coronary intervention (pPCI). Data from Acute Coronary Treatment and Intervention Outcomes Network Registry®-Get With the Guidelines™ (ACTION Registry-GWTG) from two PCI-hospitals that are utilizing RIPC during inter-facility helicopter transport of STEMI patients for pPCI between March, 2013 and September, 2015 were used for this study. The analyses were limited to inter-facility STEMI patients transported by helicopter with LVEF <55% after pPCI. The outcome measures were occurrence of clinical HF and serum level of brain-type natriuretic peptide (BNP). Out of the 150 STEMI patients in this analysis, 92 patients received RIPC and 58 did not. The RIPC and non-RIPC groups were generally similar in demographic and clinical characteristics except for lower incidence of cardiac arrest in the RIPC group (3/92 [3.3%] versus 13/58 [22.4%], p=0.002). STEMI patients who received RIPC were less likely to have in-hospital clinical HF compared to patients who did not receive RIPC (3/92 [3.3%] versus 7/58 [12.1%]; adjusted OR=0.22, 95% CI 0.05-0.92, p=0.038) after adjusting for baseline differences. In subgroup analysis, RIPC was associated with lower BNP (123 [interquartile range, 17.0-310] versus 319 [interquartile range, 106-552], p=0.029). RIPC applied during inter-facility air transport of STEMI patients for pPCI is associated with reduced incidence of clinical HF and serum BNP. Copyright © 2016 Elsevier Inc. All rights reserved.

We assessed the association between PCI and long-term mortality in octogenarians with ACS. Methods and results: We followed 353 consecutive patients aged ≥80 years hospitalized with ACS during 2006–2007. Among them, 182 were treated with PCI, whereas 171 were not. PCI-treated patients were younger and more often male, and had less stroke and dependency in activities of daily living, but there were no significant differences in occurrence of diabetes mellitus, chronic obstructive pulmonary disease, hypertension, and uncured malignancies between the two groups. The association between PCI and all-cause mortality was assessed in the overall cohort and a 1:1 matched cohort based on propensity score (PS. In overall cohort, 5-year all-cause mortality was 46.2% and 89.5% in the PCI and non-PCI groups, respectively. Cox regression analysis in overall cohort by adjustment for ten baseline variables showed statistically significant association between PCI and reduced long-term mortality (P<0.001, hazard ratio 0.4, 95% confidence interval [CI] 0.2–0.5.

    Full Text Available Background. The present study aimed to evaluate the prevalence and prognosis of residual lipid abnormalities in statin-treated acute coronary syndrome (ACS patients after percutaneous coronary intervention (PCI. Subjects and Methods. A total of 3,047 ACS patients who underwent PCI and received statin therapy were included. Plasma concentrations of LDL-C, HDL-C, and TG were measured. For the follow-up study, major adverse cardiovascular cerebrovascular events (MACCE; including total death, cardiovascular death, myocardial infarction, and revascularization were documented. Results. A total of 93.14% of all individuals were followed up for 18.1 months (range, 0–29.3 months. Of all 3,047 patients, those with a suboptimal goal were 67.75%, 85.85%, and 33.64% for LDL-C, HDL-C, and TG levels, respectively. Multiple Cox regression analysis revealed there were significant increases in cumulative MACCE of 41% (HR = 1.41, 95% CI [1.09–1.82], p=0.008, and revascularization of 48% (HR = 1.48, 95% CI [1.10–1.99], p=0.01 in low HDL-C patients with ACS after PCI, but not the high TG group at the end of study. Conclusions. Our results showed there is high rate of dyslipidemia in Chinese ACS patients after PCI. Importantly, low HDL-C but not high TG levels are associated with higher MACCE and revascularization rates in ACS patients after PCI.

    2004-09-01

    We attempted to determine if aggressive detection of angiographic adverse events during coronary intervention could predict subsequent creatine kinase (CK)-MB elevations. During coronary intervention, both fluoroscopy and cine angiography were used to detect angiographic adverse events. At least one angiographic adverse event occurred in 133/251 (53%) of procedures. CK-MB elevation occurred in 24% of procedures. Slow flow during the procedure (P=0.002) and chest discomfort at the end of the procedure (P=0.007) were the strongest predictors of CK-MB elevation. Among procedures with no angiographic adverse events, CK-MB elevation occurred in 15/121 (12%), accounting for 25% of CK-MB elevations. We conclude that CK-MB elevation occurs after angiographically uncomplicated coronary interventions even when angiographic adverse events are aggressively detected. Routine monitoring of cardiac enzymes is necessary to detect all patients who will experience myocardial injury after coronary intervention.

    The aim of this study was to examine the independent impact of various care pathways, including those involving transradial intervention (TRI) and same-day discharge (SDD) after elective percutaneous coronary intervention (PCI), on hospital costs. PCI is associated with costs of $10 billion annually. Alternative payment models for PCI are being implemented, but few data exist on strategies to reduce costs. Various PCI care pathways, including TRI and SDD, exist, but their association with costs and outcomes is unknown. In total, 279,987 PCI patients eligible for SDD in the National Cardiovascular Data Registry CathPCI Registry linked to Medicare claims files were analyzed. Hospital costs in 2014 U.S. dollars were estimated using cost-to-charge ratios. Propensity scores for TRI and SDD, with propensity adjustment via inverse probability weighting, was performed. Of the 279,987 PCI procedures, TRI was used in 9.0% (13.5% of which were SDD), and SDD was used in 5.3% of cases (23.1% of which were TRI). TRI (vs. transfemoral intervention) was associated with lower adjusted costs of $916 (95% confidence interval [CI]: $778 to $1,035), as was SDD ($3,502; 95% CI: $3,486 to $3,902). The adjusted cost associated with TRI and SDD was $13,389 (95% CI: $13,161 to $13,607), while the cost associated with transfemoral intervention and non-same-day discharge was $17,076 (95% CI: $16,999 to $17,147), a difference of $3,689 (95% CI: $3,486 to $3,902; p associated with fewer complications and lower in-hospital costs. These findings have important implications for changing the current PCI care pathways to improve outcomes and reduce costs. Copyright © 2017 American College of Cardiology Foundation.

    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.

    Numerous advances and innovative therapies have been introduced in interventional cardiology over the recent years, since the first introduction of balloon angioplasty, but bioresorbable scaffold is certainly one of the most exciting and attracting one. Despite the fact that the metallic drug-eluting stents have significantly diminished the re-stenosis ratio, they have considerable limitations including the hypersensitivity reaction to the polymer that can cause local inflammation, the risk of neo-atherosclerotic lesion formation which can lead to late stent failure as well as the fact that they may preclude surgical revascularization and distort vessel physiology. Bioresorbable scaffolds overcome these limitations as they have the ability to dissolve after providing temporary scaffolding which safeguards vessel patency. In this article we review the recent developments in the field and provide an overview of the devices and the evidence that support their efficacy in the treatment of CAD. Currently 3 devices are CE marked and in clinical use. Additional 24 companies are developing these kind of coronary devices. Most frequently used material is PLLA followed by magnesium.

    Full Text Available Arijit Dasgupta, Debabrata MukherjeeGill Heart Institute, University of Kentucky, Lexington, KY, USAAbstract: It is estimated that approximately a quarter of patients undergoing coronary intervention may have significant post-procedural creatinine (CK/creatinine kinase myocardial band (CK-MB elevations and approximately half may have post-procedural troponin elevations. Current data suggest that periprocedural infarction is associated with short-, intermediate-, and long-term adverse outcomes, most notably mortality. This review examines the role of clopidogrel in decreasing periprocedural myonecrosis following percutaneous coronary intervention (PCI. Clopidogrel is an important pharmacologic agent used to reduce myocardial infarction post-coronary intervention as assessed directly by the evaluation of cardiac biomarkers and indirectly by the evaluation of short-term ischemic events. The optimal dose of clopidogrel is considered to be at least 300 mg given 6 to 15 hours prior to PCI but there is considerable evidence to suggest that a loading dose of 600 mg given 2 to 6 hours prior to PCI may be more efficacious in limiting post-coronary intervention events. The benefit obtained from clopidogrel appears independent of and incremental to that of other antiplatelet and antithrombotic agents used during and after coronary intervention.Keywords: percutaneous coronary intervention, myonecrosis, clopidogrel, antiplatelet agents, myocardial infarction

    We sought to investigate the clinical impact of chronic total occlusion (CTO) in a non-infarct-related artery (IRA) on long-term cardiovascular outcomes in patients with ST-elevation myocardial infarction (STEMI). Among 5,429 patients enrolled in the CREDO-Kyoto AMI registry, the current study population consisted of 2,045 STEMI patients with multivessel disease (MVD) who underwent primary PCI within 24 hours after symptom onset. The cumulative five-year, 30-day and 30-day to five-year incidences of all-cause death were all significantly higher in the CTO group than in the non-CTO group (37.0% versus 22.0%, log-rank pfive years, during the initial 30 days, and beyond 30 days and up to five years (hazard ratio [HR]: 1.47, 95% confidence interval [CI]: 1.18-1.84, p=0.0009; HR: 1.49, 95% CI: 1.04-2.13, p=0.03; and HR: 1.61, 95% CI: 1.23-2.07, p=0.0006, respectively). CTO in a non-IRA was associated with increased five-year mortality in STEMI patients with MVD. This was consistently seen even after excluding early deaths within 30 days of the index STEMI event.

    The quality assurance of a percutaneous coronary intervention (PCI) program is particularly important when the volume of procedures is low in the center. Determine predictors of the 30-day and long-term incidence of stent thrombosis, myocardial infarction, and death from any cause for all PCIs performed at Tripler Army Medical Center from January 2002 to June 2012. 929 PCIs were performed in 795 patients, resulting in an average PCI volume of 88 per year. Follow-up data were obtained for 99.8% of the patients at 30 days and for 83% at 3 years. 18 deaths occurred during the first 30 days after PCI, with an observed morality rate of 2.26%. Multivariate logistic regression identified independent predictors of death at 30 days: stent thrombosis (OR 96), acute myocardial infarction, hemodynamic instability (OR 47), emergent (OR 17) or salvage (OR 28) PCI, and the need for preprocedural balloon pumping (OR 27). The long-term survival Kaplan-Meier estimates were 94% at 1 year and 90.4% at 3 years. The 30-day mortality was similar to the expected mortality based on the risk factors in the New York State Registry model, and long-term survival was comparable with that reported in large registries.

    To construct a model to predict long-term bleeding events following percutaneous coronary intervention (PCI). Treatment with dual antiplatelet therapy following PCI involves balancing the benefits of preventing ischemic events with the risks of bleeding. There are no models to predict long-term bleeding events after PCI. We analyzed 1-year bleeding outcomes from 3,128 PCI procedures in the Patient Risk Information Services Manager (PRISM) observational study. Patient-reported bleeding events were categorized according to Bleeding Academic Research Consortium (BARC) definitions. Logistic regression analysis was used to develop a model predicting BARC ≥ 1 bleeding. BARC 0, 1, 2 or 3 bleeding was observed in 574 (18.4%); 2382 (76.2%); 114 (3.6%); and 58 (1.8%) patients, respectively. Compared to patients who had no bleeding, patients with BARC ≥ 1 bleeding were more often female (30 vs. 23%), Caucasian (94 vs. 83%), had a higher incidence of drug eluting stent (DES) implantation (83 vs. 76%) and warfarin therapy (7.4 vs. 3.9%), and a lower incidence of diabetes (31 vs. 45%; P-value bleeding events as well (c-statistic = 0.653). Bleeding is common in the first year after PCI, and can be predicted by pre-procedural patient characteristics and use of DES. Objective estimates of bleeding risk may help support shared decision-making with respect to stent selection and duration of antiplatelet therapy following PCI. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Full Text Available Background: Percutaneous coronary intervention (PCI of chronic total occlusion (CTO is one of the most challenging procedures in interventional cardiology. New techniques and devices have made possible to face these complex procedures. Intravascular ultrasound (IVUS reveals special features and contributes greatly to procedural success.Method: We analysed retrospectively IVUS contribution and findings in 23 cases of a total 46 CTOs PCI from February 2009 to August 2010 in our cath lab. Both true and functional CTO were included in this study. The procedure was considered successful when a TIMI III flow was reached in the occluded vessel after stent implantation with a residual stenosis less than 30%. IVUS features and contribution in CTO-PCI were analysed. All data were introduced in SPSS version 15 (SPSS Inc. Chicago, Illinois, USA. Continuous variables were described by mean ± SD and categorical variables were expressed as percentage. A P<0.05 was considered statistically significant.Results: 46 PCIs in 34 patients were performed during 19 months in our centre. The procedure was successful in 28 cases (60.9%.. IVUS was performed in 23 (82.1% of successful procedures. IVUS revealed calcium somewhere in 17 (73.9%. Despite wire angiographic verification in true lumen distally IVUS showed subintimal wire position in part of CTO segment in 6(26.1%. In 22(95.7% of cases IVUS allowed both the wire position verification in true lumen and the vessel measurement before stent implantation. In 1(4.3% case a second wire was introduced into true lumen guided by IVUS after realising that the first wire was in false lumen. We could not find significant relation between calcium presence and subintimal wire penetration in CTO segment (p: 0.14 Conclusions: IVUS showed calcium in CTO segment in a high percentage of cases. It is not unusual to find wire penetration in subintimal space in part of CTO segment. IVUS has a key contribution in the step by step

    Purpose To compare the 1-year outcomes of a durable polymer Zotarolimus-eluting stent (ZES) versus a biodegradable polymer Biolimus-eluting stent (BES) in patients undergoing percutaneous coronary intervention. Materials and Methods A total of 2083 patients from 2 different registries, 1125 treated with BES in NOBORI registry and 858 received ZES in CONSTANT registry were included in this study. Clinical outcomes were compared with the use of propensity score matching (PSM). The primary endpoint was a composite of major adverse cardiovascular and cerebrovascular events (MACCEs) including cardiac death, myocardial infarction, clinically driven target lesion revascularization and stroke. Secondary end points were individual components of MACCEs as well as the incidence of stent thrombosis at 1-year follow-up. Results After PSM, 699 matched pairs of patients (n=1398) showed no significant difference between BES and ZES in the risk of composite MACCEs at 1 year (2.6% vs. 1.7%; p=0.36). Cardiac death was not statistically different between groups (0.7% vs. 0.4%, p=0.73). Target lesion revascularization rate was also similar between BES and ZES (1.1% vs. 0.7%, p=0.579). Non-Q wave myocardial infarction, as well as target-vessel revascularization rate, was similar between the two groups (0.14% for BES and 0.72% for ZES). Both stent types were excellent with no cases of stent thrombosis and rate of Q wave myocardial infarction reported during the follow-up period. Conclusion In this cohort of patients treated with BES or ZES, the rate of MACCEs at 1 year was low and significantly not different between both groups. PMID:28120558

    Objectives We aimed to compare quality of life benefits of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) with non-CTO PCI. Background Data quantifying the benefits of PCI of CTO are inconsistent. Methods We leveraged a 10-center prospective PCI registry including Seattle Angina Questionnaire (SAQ) assessment at the time of PCI and in follow-up. We propensity matched attempted CTO PCIs with up to 10 non-CTO PCIs. The primary analysis compared changes between baseline and 6 months in SAQ Physical Limitation (PL), Quality of Life (QoL) and Angina Frequency (AF) scores as well as the Rose Dyspnea scores (RDS) and the EQ5D Visual Analogue Scale (VAS). Non-inferiority was assessed for quality of life changes between CTO and non-CTO PCI. Results In 3,303 patients enrolled, 167 single-vessel CTOs were attempted; 147 (88%) were matched with 1,616 non-CTO PCI. Baseline PL (73.0 vs. 77.4, p=0.039) and VAS (66.4 vs. 70.8, p=0.005) scores were lower for CTO. There was no difference in AF, QoL or RDS scores. At 6-month follow-up, all SAQ scores improved (pCTO and Non-CTO (p=NS for all). VAS scores remained lower for CTO, but improved in both groups (pCTO PCI was not inferior to non-CTO PCI (p≤0.02 for all). Conclusions Symptoms, function, QoL and dyspnea improve to the same degree following CTO PCI as compared with non-CTO PCI. Symptom relief supports CTO PCI to improve patients’ quality of life.

    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.

    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.

    To investigate the change and clinical significance of clopidogrel on platelet membrane CD40L in coronary artery disease patients before and after percutaneous coronary intervention (PCI). Methods 30 cases who were diagnosis coronary artery diseases(CAD) by coronary angiography, mean age 56 ± 9 years old. All the patients who had no antiplatelet aggregation contraindication, were treated with standard anti angina pectoris drugs. Before PCI, all the patients took clopidogrel 75 mg per day. Activated platelet membrane CD40L express rate was measured by flow cytometry before and after PCI 6 hours. Results Activated platelet membrane CD40L express rate were 3.73 ± 2.15and 2.46 ± 0.90, respectively in 30 patients before and after PCI 6 hours. Activated platelet membrane CD40L express rate was significantly decrease after PCI 6 hours than that before PCI ( P < 0.01 ). Conclusions Clopidogrel has significance effect on platelet membrane CD40L in coronary artery disease patients undergoing PCI. Clopidogrel can suppression platelet activation and prevent thromboembolism event occurrence.

    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{sup 2}, while the staged group, to 139.2 ± 75.3 Gycm{sup 2} (p < 0.001). Ad hoc percutaneous coronary intervention reduced radiation exposure as compared with diagnostic and therapeutic procedures performed at two separate times.

    % with unstable angina (UA, two (0.2% with atypical manifestations of ACS and 26 (3% with non-cardiac chest pain. 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.

    Dextrocardia with situs inversus is a rare clinical entity with an estimated incidence ranges from 1 in 8000 to 1 in10,000. Percutaneous intervention in patient with dextrocardia and situs inversus is clinically challenging due to abnormal orientation of coronary geometry and the intervention requires appropriate use of guiding catheters, engagement technique, appropriate radiological angles as well as views. In this case-report, we describe percutaneous intervention with stenting in 48-year-old male patient with dextrocardia and situs inversus. We successfully deployed drug-eluting stents in right coronary artery and left circumflex artery.

    Coronary artery disease coexists in a clinically relevant number of patients with atrial fibrillation and it often requires percutaneous coronary intervention. These patients represent a particular challenge for clinicians in terms of antithrombotic management. They require combined antiplatelet-anticoagulant therapy to reduce the risk of recurrent ischemic cardiac events and stroke; however, this antithrombotic strategy is associated with an increased risk of bleeding complications. In the absence of randomized, controlled clinical trials, the majority of current recommendations rely on the results of cohort studies, meta-analyses, post-hoc analyses and subgroup analyses of large, phase III studies. Based on the available evidence, the present review discusses the optimal antithrombotic strategy for patients receiving chronic anticoagulant therapy due to atrial fibrillation who require antiplatelet treatment after acute coronary syndrome and/or percutaneous coronary intervention, and discusses the issue of dental procedures. The correct planning of therapy significantly reduces the risk of bleeding complications and thromboembolic events.

    Full Text Available Background: Despite recent improvement in coronary intervention, there are many controversies about it’s results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics. Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas. Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA, and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG had no significant differences between two groups. Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

    Internet interventions often rely on convenience sampling, yet convenience samples may differ in important ways from systematic recruitment approaches. The purpose of this study was to evaluate potential demographic, medical, and psychosocial differences between Internet-recruited and registry-recruited cancer survivors in an Internet-based intervention. Participants were recruited from a cancer registry (n = 80) and via broad Internet outreach efforts (n = 160). Participants completed a set ...

    Full Text Available Background: The aim of the present study was to develop a scoring system for predicting 1-year major adverse cardiac events (MACE, including mortality, target vessel or target lesion revascularization, coronary artery bypass graft surgery, and non-fatal myocardial infarction after percutaneous coronary intervention (PCI.Methods: The data were extracted from a single center PCI registry. The score was created based on the clinical, procedural, and laboratory characteristics of 8206 patients who underwent PCI between April 2004 and October 2009. Consecutive patients undergoing PCI between November 2009 and February 2011 (n= 2875 were included as a validation data set. Results: Diabetes mellitus, increase in the creatinine level, decrease in the left ventricular ejection fraction, presentation with the acute coronary syndrome, number of diseased vessels, primary PCI, PCI on the left anterior descending artery and saphenous vein graft, and stent type and diameter were identified as the predictors of the outcome and used to develop the score (R² = 0.795. The models had adequate goodness of fit (Hosmer-Lemeshow statistic; p value = 0.601 and acceptable ability of discrimination (c-statistics = 0.63. The score categorized the individual patients as low-, moderate-, and high-risk for the occurrence of MACE. The validation of the model indicated a good agreement between the observed and expected risks.Conclusion: An individual risk-scoring system based on both clinical and procedural variables can be used conveniently to predict 1-year MACE after PCI. Risk classification based on this score can assist physicians in decision-making and postprocedural health care.

    We studied the outcome of cardiopulmonary resuscitation (CPR) in patients undergoing coronary angiography (CA) and/or percutaneous coronary interventions (PCI). Of 51,985 CA and PCI patients treated between January 1, 1990, and December 31, 2000, 114 required CPR. Records were reviewed for relationships between patient characteristics and various procedures and short-term survival. Long-term survival was compared with that of a matched cohort of patients who did not have an arrest during catheterization and a matched cohort from the general Minnesota population. Over the 11-year period, the overall incidence of CPR was 21.9 per 10,000 procedures. This rate decreased from 33.9 per 10,000 before 1995 to 13.1 per 10,000 after 1995. Overall survival to hospital discharge after CPR was 56.1%. Survival to discharge was less frequent with a history of congestive heart failure, previous coronary artery bypass graft surgery, hemodynamic instability during the procedure, and with prolonged or emergent catheterizations. Pulseless electrical activity (versus asystole or ventricular fibrillation) indicated very poor short-term survival. Interestingly, short-term survival was not related to the extent of coronary artery disease. Long-term survival of patients who survived cardiac arrest was comparable to that of those who did not have arrest during catheterization. In conclusion, the incidence of periprocedural CPR during diagnostic or interventional coronary procedures decreased after 1995. Patients who received CPR in the cardiac catheterization lab have a remarkably frequent survival to hospital discharge rate. Long-term survival of these patients is only minimally reduced.

    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.

    Acute kidney injury (AKI) after percutaneous coronary intervention (PCI) is common, morbid, and costly; increases patients' mortality risk; and can be mitigated by limiting contrast use. To examine the national variation in AKI incidence and contrast use among US physicians and the variation's association with patients' risk of developing AKI after PCI. This cross-sectional study used the American College of Cardiology National Cardiovascular Data Registry (NCDR) CathPCI Registry to identify in-hospital care for PCI in the United States. Participants included 1 349 612 patients who underwent PCI performed by 5973 physicians in 1338 hospitals between June 1, 2009, and June 30, 2012. Data analysis was performed from July 1, 2014, to August 31, 2016. The primary outcome was AKI, defined according to the Acute Kidney Injury Network criteria as an absolute increase of 0.3 mg/dL or more or a relative increase of 50% or more from preprocedural to peak creatinine. A secondary outcome was the mean contrast volume as reported in the NCDR CathPCI Registry. Physicians who performed more than 50 PCIs per year were the main exposure variable of interest. Hierarchical regression with adjustment for patients' AKI risk was used to identify the variation in AKI rates, the variation in contrast use, and the association of contrast volume with patients' predicted AKI risk. Of the 1 349 612 patients who underwent PCI, the mean (SD) age was 64.9 (12.2) years, 908 318 (67.3%) were men, and 441 294 (32.7%) were women. Acute kidney injury occurred in 94 584 patients (7%). A large variation in AKI rates was observed among individual physicians ranging from 0% to 30% (unadjusted), with a mean adjusted 43% excess likelihood of AKI (median odds ratio, 1.43; 95% CI, 1.41-1.44) for statistically identical patients presenting to 2 random physicians. A large variation in physicians' mean contrast volume, ranging from 79 mL to 487 mL with an intraclass correlation coefficient of 0

    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.

    Objective:To explore the value of angiographic diagnosis and interventional therapy of the coronary artery fine branch fistula.Methods:All of the 18 patients with coronary artery fine branch fistula underwent selective coronary arteriography,7 underwent interventional therapy, while 8 underwent prosthesis for coronary artery fistula (CAF) under extracorpored circulation. Results:Among 18 cases of coronary artery fine branch fistula, 7 happened in right coronary artery (38.9%), 11 in left coronary artery (61.1%). Among the 11 cases in left coronary artery,5 happened in descending anterior branch, 5 occurred in left circumflex branch, 1 arised from both left anterior branch and left circumflex branch. Among the 18 cases, there are 10 cases of coronary-to-pulmonary artery fistula (55.6%), 5 cases of fistula draining into right atrium (27.8%), 2 cases of fistula draining into left atrium (11.1%) and 1 draining into right ventricle (5.6%). Interventional treatment was successful in 7 patients. During the 12 months' follow-up, there was no cardiovascular events. Conclusion:Selective coronary angiography is the first choice for diagnosing the coronary artery fine branch fistula. In respect of therapy, besides of surgical treatment, intervention is still a rather good measure presently.

    Anomalous left coronary artery from the pulmonary artery(ALCAPA) is most commonly diagnosed within the first year of life with congestive heart failure symptomatology reflecting left ventricle(LV) dysfunction. The late diagnosis of ALCAPA is presented in a 5-yearold without significant LV dysfunction, mild LV dilatation and only mild mitral regurgitation that did not change significantly after surgery. The timing of surgical intervention in the late diagnosis of ALCAPA remains unclear despite risks of significant ongoing myocardial injury secondary to coronary artery hypoperfusion and progressive mitral valve dysfunction. Intervention in this case allows for revascularization which may reverse ventricular and valvular dysfunction.

    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.

    2001-04-01

    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.

    BACKGROUND Health-related quality of life (HRQOL) evaluation is an important measure of the impact of the disease. As more people with coronary heart disease (CHD) live longer, doctors and researchers want to know how they manage in day to day life. It looked like adults with CHD had a decrease QOL. The aim of this study was to comparison of HRQOL of patients who underwent percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) and to assess its main determinants in the whole sample of coronary artery disease (CAD) patients. METHODS The study was carried out to estimate HRQOL of 109 patients who underwent invasive coronary revascularization [PCI (n = 75) and CABG (n = 34)]. We applied HRQOL after 6 months and 2 years in both groups and scores were compared. The HRQOL data were obtained using MacNew Heart Disease questionnaire with dimensions emotional, physical and social that estimated. Data entry and analysis were performed by SPSS. RESULTS A total MacNew scale in CABG and PCI group in 6 months after treatment were 45.32 ± 13.75 and 53.52 ± 15.63, respectively (P = 0.010). After 2 years HRQOL mean changed to 51.176 ± 14.80 and 49.55 ± 16.22, respectively, in CABG and PCI group (P = 0.428). Our results in within-group analysis showed total MacNew scale and its subscales were changed significantly after 2 years in CABG and PCI group’s scores were detected. We found in the whole sample of CAD patients those who had a higher level of income and education and were not either overweight or obese experienced better HRQOL. CONCLUSION Our results showed that patients who underwent PCI experienced significantly higher HRQOL in 6 months after revascularization but over 24 months follow-up no difference was observed between the two groups.

    Full Text Available Introduction. The optimal revascularization strategy for unprotected left main coronary disease (ULMCD is the subject of ongoing debate and patients with ULMCD still represent a challenge for interventionalist, especially in the setting of an acute coronary syndome (ACS. Case report. We presented two cases of percutaneous treatment of ULMCD in the settings of ACS (ST Segment Myocardial Infarction and Non ST Segment Myocardial Infarction - STEMI and NSTEMI in a catheterization laboratory without back-up of cardiosurgical department. Both patients were hemodynamically unstable with clinical signs of cardiogenic shock. Coronary angiography revealed left main thromobosis and using intra-aortic balloon pump as hemodynamic support primary angioplasty procedures were performed. Immediately after the procedures the patients hemodynamically improved and remained stable till discharge from hospital. Conclusion. Percutaneous coronary intervention (PCI has become the most common strategy of revascularization in ACS patients with ULMCD and is generally preferred in patients with multiple comorbidities and/or in very unstable patients. In cases with no cardiosurgical departments PCI is an inevitable, bail-out, life saving procedure.

    The aim was to examine timing, causes, and predictors of death during long-term follow-up after contemporary percutaneous coronary intervention (PCI) using a large multicenter Australian registry. The cohort consisted of 10,682 consecutive patients from the Melbourne Interventional Group registry undergoing PCI (February 2004 through November 2009). For the first time in Australia, long-term mortality rates of a PCI cohort were defined by linkage to the National Death Index database. The cohort (mean age 64 ± 12 years) comprised 75% men, 24% diabetics, 59% with multivessel disease, 4.4% with renal failure, 25% with ST-elevation myocardial infarction (STEMI), 2.5% with cardiogenic shock, and 5.1% with heart failure. Drug-eluting stents (DES) were used in 43% of cases. Mean follow-up was 3.2 ± 0.5 years. In-hospital, 30-day, 12-month, and long-term (3.2 ± 0.5 years) mortalities were 1.6% (80% cardiac), 2.1% (79%), 3.9% (61%), and 8.2% (50%), respectively. Independent predictors of long-term mortality included age (hazard ratio 1.05, 95% confidence interval 1.04 to 1.06), cardiogenic shock (4.58, 3.60 to 5.83), renal failure (3.14, 2.58 to 3.82), previous heart failure (1.97, 1.60 to 2.41), STEMI (1.79, 1.47 to 2.18), peripheral vascular disease (1.72, 1.4 to 2.11), non-STEMI (1.58, 1.32 to 1.90), multivessel disease (1.47, 1.24 to 1.74), current smoking (1.39, 1.12 to 1.71), diabetes (1.36, 1.16 to 1.59), and cerebrovascular disease (1.33, 1.06 to 1.60, p long-term mortality after PCI, whereas DES use in this large registry was not associated with late mortality risk.

    Background Little is known about Emergency Medical Services (EMS) use and pre-hospital triage of patients with acute ST-elevation myocardial infarction (STEMI) in Arabian Gulf countries. Methods Clinical arrival and acute care within 24 h of STEMI symptom onset were compared between patients transferred by EMS (Red Crescent and Inter-Hospital) and those transferred by non-EMS means. Data were retrieved from a prospective registry of 36 hospitals in 6 Arabian Gulf countries, from January 2014 to January 2015. Results We enrolled 2,928 patients; mean age, 52.7 (SD ±11.8) years; 90% men; and 61.7% non-Arabian Gulf citizens. Only 753 patients (25.7%) used EMS; which was mostly via Inter-Hospital EMS (22%) rather than direct transfer from the scene to the hospital by the Red Crescent (3.7%). Compared to the non-EMS group, the EMS group was more likely to arrive initially at a primary or secondary health care facility; thus, they had longer median symptom-onset-to-emergency department arrival times (218 vs. 158 min; p˂.001); they were more likely to receive primary percutaneous coronary interventions (62% vs. 40.5%, p = 0.02); they had shorter door-to-needle times (38 vs. 42 min; p = .04); and shorter door-to-balloon times (47 vs. 83 min; p˂.001). High EMS use was independently predicted mostly by primary/secondary school educational levels and low or moderate socioeconomic status. Low EMS use was predicted by a history of angina and history of percutaneous coronary intervention. The groups had similar in-hospital deaths and outcomes. Conclusion Most acute STEMI patients in the Arabian Gulf region did not use EMS services. Improving Red Crescent infrastructure, establishing integrated STEMI networks, and launching educational public campaigns are top health care system priorities. PMID:26807577

    The SYNTAX [Synergy Between percutaneous coronary intervention (PCI) With Taxus and coronary artery bypass surgery (CABG)] score is a decision-making tool in interventional cardiology. However, several facts still remain to be addressed: What about PCI or CABG with a low versus a high score respectively? And what about PCI with a low score versus CABG with a high score? Electronic databases were carefully searched for relevant publications. Odds ratios (OR) with 95% confidence intervals (CIs) were calculated and the analysis was carried out by RevMan 5.3. Eleven studies with a total number of 11,037 patients were included. In terms of clinical outcomes, this analysis showed PCI to have significantly favored patients with a low versus a high SYNTAX score. In patients who were re-vascularized by CABG, mortality and major adverse cardiac events were significantly lower with a low SYNTAX score. However, when PCI with a low SYNTAX score was compared with CABG with a high SYNTAX score, no significant difference in mortality and combined death/stroke/myocardial infarction were observed. In conclusion, the SYNTAX score might be considered useful in interventional cardiology. Nevertheless, the fact that it has limitations when compared to newer tools should also not be ignored.

    OBJECTIVES The goal of this study was to examine the calibration of a validated risk-adjustment model in very high-risk percutaneous coronary intervention (PCI) cases and assess whether sites’ case mix affects their performance ratings. BACKGROUND There are concerns that treating PCI patients with particularly high-risk features such as cardiogenic shock or prior cardiac arrest may adversely impact hospital performance ratings. However, there is little investigation on the validity of these concerns. METHODS We examined 624,286 PCI procedures from 1,168 sites that participated in the CathPCI Registry in 2010. Procedural risk was estimated using the recently published Version 4 National Cardiovascular Data Registry (NCDR) PCI risk-adjusted mortality (RAM) model. We calculated observed/expected mortality using several risk classification methods, and simulated hospital performance after combining their highest risk cases over 2 years into a single year. RESULTS In 2010, crude in-hospital PCI mortality was 1.4%. The NCDR model was generally well calibrated among high risk, however there was slight overprediction of risk in extreme cases. Hospitals treating the highest overall expected risk PCI patients or those treating the top 20% of high-risk cases had lower (better) RAM ratings than centers treating lower-risk cases (1.25% vs. 1.51%). The observed/expected ratio for top-risk quintile versus low-risk quintile was 0.91 (0.87 to 0.96) versus 1.10 (1.03 to 1.17). Combining all the high-risk patients over a 2-year period into a single year also did not negatively impact the site’s RAM ratings. CONCLUSIONS Evaluation of a contemporary sample of PCI cases across the United States showed no evidence that treating high-risk PCI cases adversely affects hospital RAM rates. PMID:25499301

    Prior studies have found that smokers undergoing thrombolytic therapy for ST-segment elevation myocardial infarction have lower in-hospital mortality than nonsmokers, a phenomenon called the "smoker's paradox." Evidence, however, has been conflicting regarding whether this paradoxical association persists in the era of primary percutaneous coronary intervention. We used the 2003-2012 National Inpatient Sample databases to identify all patients aged ≥18 years who underwent primary percutaneous coronary intervention for ST-segment elevation myocardial infarction. Multivariable logistic regression was used to compare in-hospital mortality between smokers (current and former) and nonsmokers. Of the 985 174 patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention, 438 954 (44.6%) were smokers. Smokers were younger, were more often men, and were less likely to have traditional vascular risk factors than nonsmokers. Smokers had lower observed in-hospital mortality compared with nonsmokers (2.0% versus 5.9%; unadjusted odds ratio 0.32, 95% CI 0.31-0.33, Pparadox also applies to ST-segment elevation myocardial infarction patients undergoing primary percutaneous coronary intervention. © 2016 The Authors.

    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.

    Coronary microcirculatory function after primary percutaneous coronary intervention (pPCI) in patients with acute myocardial infarction is important determinant of infarct size (IS). Our aim was to investigate the utility of coronary flow reserve (CFR) and diastolic deceleration time (DDT) of the infarct artery (IRA) assessed by transthoracic Doppler echocardiography after pPCI for final IS prediction. In 59 patients, on the 2nd day after pPCI for acute anterior myocardial infarction, transthoracic Doppler analysis of IRA blood flow was done including measurements of CFR, baseline DDT and DDT during adenosine infusion (DDT adeno). Killip class, myocardial blush grade, resolution of ST segment elevation, peak creatine kinase-myocardial band and conventional echocardiographic parameters were determined. Single-photon emission computed tomography myocardial perfusion imaging was done 6 weeks later to define final IS (percentage of myocardium with fixed perfusion abnormality). IS significantly correlated with CFR (r = -0.686, p 20 %), the best cut-off for CFR was <1.73 (sensitivity 65 %, specificity 96 %) and for DDT adeno ≤720 ms (sensitivity 81 %, specificity 96 %). CFR and DDT during adenosine are independent and powerful early predictors of final IS offering incremental prognostic information over conventional parameters of myocardial and microvascular damage and tissue reperfusion.

    Full Text Available The Registry of Myocardial Infarctions (MI Registry is a national registry in Iran that collects and reports the data on myocardial infarctions. Its main advantage is that it covers the whole country and is mandatory for hospitals to register the MI cases in it. Then, the qualified individuals at the provincial and national levels can get intended reports and make appropriate decisions. Such reports, further to the policy makers and managers, can be very valuable for researchers. The registry is a unique and comprehensive source of data that can provide priceless reports which can be used in management, policy making, resource allocation, and for research purposes. The data of MI patients from all around the country are entered into the registry by the hospitals in which the MI patients are admitted. The data include the demographic information (name, gender, date of birth, literacy, nationality, health insurance, city, and province, admission data (date and time of the first signs of the attack, date and time of admission in the hospital emergency department, date and time of admission in cardiac care unit-CCU, name of the doctor, and the number of patient’s medical record, medical history (coronary heart disease, hypertension, diabetes, high cholesterol, number of cigarettes if smoking, history of CABG and/or PCI and its date, clinical condition (the patient’s condition in terms of rhythm and heart block according to the diagnosis of the doctor, interventions (thrombolytic therapy, CABG, PCI, and date and time of each intervention if applied, laboratory results (positive or negative Troponin T and Troponin I, amount of CPKMB, maximum Troponin T and Troponin I, and date and time of each laboratory test, and the discharge information (the patient’s status when discharged from CCU-stable or dead, prescribed drugs, final diagnosis, and date and time of discharge.

    The OLmesartan on the progression of coronary atherosclerosis: evaluation by IntraVascular UltraSound (OLIVUS) trial demonstrated that an angiotensin II receptor blocker, olmesartan, reduces the rate of coronary atheroma progression as evaluated by intravascular ultrasound in patients with stable angina pectoris undergoing percutaneous coronary intervention. This substudy examined the impact of olmesartan on serum biomarkers and the relationship between biomarker changes and atheroma progression. Patients in the OLIVUS trial (n = 247) were randomly assigned to a control group or the olmesartan group. A subgroup of these patients (n = 135, 55 %) was analyzed at baseline and at 14 months. Patients' characteristics and blood-pressure control were identical between the control group (n = 65) and the olmesartan group (n = 70), and also between the subpopulation and total population. The change in the level of high-sensitivity C-reactive protein (hs-CRP) (mg/l) and adiponectin (μg/ml) was significantly greater in the olmesartan group than in the control group (between-group differences: 0.5 and -0.7; 95 % confidence interval: 0.2-0.8 and -1.3 to -0.1; P = 0.001 and 0.02, respectively). Multiple regression analysis revealed that the nominal changes in total atheroma volume and percent atheroma volume were significantly associated with the nominal change in hs-CRP in the olmesartan group but not in the control group. Olmesartan reduced hs-CRP in patients with stable angina, and this correlated with the change in coronary atheroma.

    Vigorous cholesterol lowering with diet, drugs, or a combination has been shown to slow, arrest, or even reverse atherosclerosis. Residential lifestyle intervention programs have successfully lowered serum cholesterol levels and other coronary risk factors, but they have the disadvantages of high cost and difficulty with long-term adherence. Community-based risk-reduction programs have the potential to effect change at low cost and improve long-term adherence. To assess the effectiveness of, and to develop a model for, such programs, the community-based Coronary Health Improvement Project (CHIP) was developed in Kalamazoo, Michigan. In the intensive (30-day, 40-hour), hospital-based educational program, participants are encouraged to exercise 30 minutes a day and to embrace a largely unrefined plant-food-centered diet that is high in complex carbohydrates and fiber; very low in fat, animal protein, sugar, and salt; and virtually free of cholesterol. A total of 304 enrollees in the first program were at elevated risk of coronary artery and related diseases: 70% were > or =10% above their ideal weight, 14% had diabetes, 47% had hypertension, and 32% had a history of coronary artery disease. Of the enrollees, 288 "graduated" from the program (123 men, 165 women; mean age was 55+/-11 years). Various markers of disease risk, including serum blood lipids and fasting blood glucose concentrations, were measured before and after the program. At 4 weeks, overall improvements in the participants' laboratory test results, blood pressures, weights, and body mass indexes were highly significant (p 200 mg/dL in men, 200-299 mg/dL in women).

    Objective Although risk factors of atrial fibrillation (AF) in the general population have been characterised, their impacts on patients with specific diseases are unclear. Our aim was to determine whether risk factors of AF are different in patients with and those without coronary artery disease (CAD). Methods We enrolled 1871 consecutive patients who underwent coronary angiography for evaluation of symptoms suggestive of CAD in the BOREAS-CAG Registry between August 2014 and January 2015. After exclusion of patients with valvular heart disease or a history of PCI/cardiac surgery, 1150 patients contributed to multivariate logistic regression analysis to identify risk factors of AF. We also retrieved data for 361 consecutive patients with CAD admitted to Sapporo Medical University Hospital between April 2013 and July 2014 and analysed data for 166 patients using the same inclusion and exclusion criteria as those in the BOREAS-CAG Registry. Results Unexpectedly, CAD was independently associated with the absence of AF. The patients were then divided into a non-CAD group (n=576) and a CAD group (n=574) for further analysis. The brain natriuretic peptide level showed a strong association with AF regardless of the presence or absence of CAD. In the non-CAD group, lack of statin use was independently associated with AF, whereas high serum uric acid level was an independent explanatory variable of AF in the CAD group. The association of AF with uric acid was confirmed in a separate group of patients (n=166) enrolled in the CAD cohort in Sapporo Medical University Hospital. Conclusions Major risk factors of AF are different in patients with CAD and those without CAD. Patients with CAD are more likely to develop AF when the serum uric acid level is high, whereas no statin administration predicts development of AF in patients without CAD. PMID:28123767

  11. Association between gender, process of care measures, and outcomes in ACS in India: results from the detection and management of coronary heart disease (DEMAT registry.

    Full Text Available BACKGROUND: Studies from high-income countries have shown that women receive less aggressive diagnostics and treatment than men in acute coronary syndromes (ACS, though their short-term mortality does not appear to differ from men. Data on gender differences in ACS presentation, management, and outcomes are sparse in India. METHODS AND RESULTS: The Detection and Management of Coronary Heart Disease (DEMAT Registry collected data from 1,565 suspected ACS patients (334 women; 1,231 men from ten tertiary care centers throughout India between 2007-2008. We evaluated gender differences in presentation, in-hospital and discharge management, and 30-day death and major adverse cardiovascular event (MACE; death, re-hospitalization, and cardiac arrest rates. Women were less likely to present with STEMI than men (38% vs. 55%, p<0.001. Overall inpatient diagnostics and treatment patterns were similar between men and women after adjustment for potential confounders. Optimal discharge management with aspirin, clopidogrel, beta-blockers, and statin therapy was lower for women than men, (58% vs. 65%, p = 0.03, but these differences were attenuated after adjustment (OR = 0.86 (0.62, 1.19. Neither the outcome of 30-day mortality (OR = 1.40 (0.62, 3.16 nor MACE (OR = 1.00 (0.67, 1.48 differed significantly between men and women after adjustment. CONCLUSIONS: ACS in-hospital management, discharge management, and 30-day outcomes did not significantly differ between genders in the DEMAT registry, though consistently higher treatment rates and lower event rates in men compared to women were seen. These findings underscore the importance of further investigation of gender differences in cardiovascular care in India.

    The predictive value of five risk score models containing clinical (PAMI-PMS, GRACE-GRS, and modified ACEF-ACEFm-scores), angiographic SYNTAX score (SXS) and combined Clinical SYNTAX score (CSS) variables were evaluated for the incidence of three procedural complications of primary percutaneous coronary intervention (pPCI): iatrogenic coronary artery dissection, angiographically visible distal embolization and angiographic no-reflow phenomenon. The mentioned scores and the incidence of procedural complications were retrospectively analyzed in 399 consecutive patients with acute ST-elevation myocardial infarction who underwent pPCI. Coronary dissection, distal embolization and no-reflow occurred in 39 (9.77%), 71 (17.79%), and 108 (27.07%) subjects, respectively. Coronary dissections were significantly associated with higher GRS, ACEFm, and CSS values (all p<0.05). PMS, GRS, ACEFm, and CSS were significantly higher in patients with no-reflow (all p<0.05), while distal embolization was not predicted by any of the calculated scores. In multiple logistic regression models, GRS and ACEFm remained independent predictors of both coronary dissections (OR 3.20, 95% CI 1.56-6.54, p<0.01 and OR 2.87, 95% CI 1.27-6.45, p=0.01, respectively) and no-reflow (OR 1.71, 95% CI 1.04-2.82, p=0.03 and OR 1.86, 95% CI 1.10-3.14, p=0.01, respectively). Whereas SXS failed to predict procedural complications related to pPCI, two simple, noninvasive risk models, GRS and ACEFm, independently predicted coronary dissections and no-reflow. Pre-interventional assessment of these scores may help the interventional cardiologist to prepare for procedural complications during pPCI.

    Acute coronary syndromes presenting with ST elevation are usually treated with emergency reperfusion/revascularisation therapy. In contrast current evidence and national guidelines recommend risk stratification for non ST segment elevation myocardial infarction(NSTEMI) with the decision on revascularisation dependent on perceived clinical risk. Risk stratification for STEMI has no recommendation. Statistical risk scoring techniques in NSTEMI have been demonstrated to improve outcomes however their uptake has been poor perhaps due to questions over their discrimination and concern for application to individuals who may not have been adequately represented in clinical trials. STEMI is perceived to carry sufficient risk to warrant emergency coronary intervention [by primary percutaneous coronary intervention(PPCI)] even if this results in a delay to reperfusion with immediate thrombolysis. Immediate thrombolysis may be as effective in patients presenting early, or at low risk, but physicians are poor at assessing clinical and procedural risks and currently are not required to consider this. Inadequate data on risk stratification in STEMI inhibits the option of immediate fibrinolysis, which may be cost-effective. Currently the mode of reperfusion for STEMI defaults to emergency angiography and percutaneous coronary intervention ignoring alternative strategies. This review article examines the current risk scores and evidence base for risk stratification for STEMI patients. The requirements for an ideal STEMI risk score are discussed.

    Full Text Available Objectives: 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. Methods: 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. Results: 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. Conclusion: 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.

  20. A Preliminary Real-Time and Realistic Simulation Environment for Percutaneous Coronary Intervention

    2015-01-01

    Full Text Available Percutaneous coronary intervention (PCI is a minimally invasive surgery procedure that is widely used in the treatment of coronary artery disease. This procedure requires interventional cardiologists to have high proficiency and therefore demands an extensive training period in order to ensure successful surgical outcome. In this paper, a realistic and real-time interactive simulator for training PCI procedure is presented. A set of new approaches for core simulation components is devised and integrated into the simulator. Trainees can interact with the virtual simulation environment with real instruments and essential maneuvers encountered in real PCI procedure. Although presently targeted at PCI, our simulator could be easily extended to mimic the necessities of any vascular interventional radiology procedures by updating vascular anatomy. Preliminary validation of the proposed physical model of instruments is conducted on vascular phantom to demonstrate its performance and effectiveness.

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.

    The objective of this study is to develop a cost-effectiveness model comparing drug eluting stents(DES) vs bare metal stent(BMS) in patients suffering of stable coronary artery disease. Using a 2-years time horizon, two simulation models have been developed: BMS first line strategy and DES first line strategy. Direct medical costs were estimated considering ambulatory and hospital costs. The effectiveness endpoint was defined as treatment success, which is the absence of major adverse cardiac events. Probabilistic sensitivity analyses were carried out using 10000 Monte-Carlo simulations. DES appeared slightly more efficacious over 2 years(60% of success) when compared to BMS(58% of success). Total costs over 2 years were estimated at 9303  for the DES and at 8926  for bare metal stent. Hence, corresponding mean cost-effectiveness ratios showed slightly lower costs(P < 0.05) per success for the BMS strategy(15520 /success), as compared to the DES strategy(15588 /success). Incremental costeffectiveness ratio is 18850  for one additional percent of success. The sequential strategy including BMS as the first option appears to be slightly less efficacious but more cost-effective compared to the strategy including DES as first option. Future modelling approaches should confirm these results as further comparative data in stable coronary artery disease and long-term evidence become available.

  3. Bioabsorbable scaffolds for the treatment of obstructive coronary artery disease: the next revolution in coronary intervention?

    2013-09-01

    Conventional drug eluting stents allow predictable long-term relief from coronary obstruction in most cases. However, rigid permanent metallic stents alter flow dynamics, abolish vascular reactivity, limit the potential for maximal vasodilation and promote ongoing inflammation and abnormalities of endothelial function. It is hypothesised that they may contribute to mal-apposition of stent struts, accelerated atheroma within the stented segment and perhaps very late stent thrombosis. Dramatic advances in bioabsorbable materials and technology have delivered the potential for a fully absorbable scaffold, which is able to mechanically support the coronary artery, and elute a drug, for a predetermined time period and is then fully absorbed in to the vascular wall. This could permit the 'normalisation' of vascular function, with a number of potential advantages including true normalisation of vasomotor function, restoration of physiological responses to stress/exercise and completion of the vascular response to stenting, without the long-term consequences related to inflammation, accelerated atherosclerosis and thrombosis. Currently, over 16 different scaffolds are at varying stages of development. This review summarises the rationale for the development of absorbable scaffolds and the principal clinical research data.

    Objective To examine sex-specific associations, if any, between per-vessel CAD extent and the risk of major adverse cardiovascular events (MACE) over a five-year study duration. Background The presence and extent of coronary artery disease (CAD) diagnosed by coronary computed tomography angiography (CCTA) is associated with increased short-term mortality and MACE. Nevertheless, some uncertainty remains regarding the influence of gender on these findings. Methods 5,632 patients (mean age 60.2 + 11.8 years, 36.5% female) from the CONFIRM (COronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter) registry were followed over the course of 5 years. Obstructive CAD was defined as ≥50% luminal stenosis in a coronary vessel. Using Cox proportional-hazards models, we calculated the hazard ratio (HR) for incident MACE among women and men, defined as death or myocardial infarction (MI). Results Obstructive CAD was more prevalent in men (42% vs. 26%, p<0.001) whereas women were more likely to have normal coronary arteries (43% vs. 27%, p<0.001). There were a total of 798 incident MACE events. After adjustment, there was a strong association between increased MACE risk and non-obstructive CAD (HR 2.16 for women, 2.56 for men, p<0.001 for both), obstructive one-vessel CAD (HR 3.69 and 2.66, p<0.001), two-vessel CAD (HR 3.92 and 3.55, p<0.001) and three-vessel/left-main CAD (HR 5.94 and 4.44, p<0.001). Further exploratory analyses of atherosclerotic burden did not identify gender-specific patterns predictive of MACE. Conclusion In a large prospective CCTA cohort followed long-term, we did not observe an interaction of gender for the association between MACE risk and increased per-vessel extent of obstructive CAD. These findings highlight the persistent prognostic significance of anatomic CAD subsets as detected by CCTA for the risk of MACE in both women and men. PMID:27056154

    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.

    2011-05-01

    The high rate of restenosis associated with percutaneous coronary intervention (PCI) procedures can be reduced with the implantation of metallic stents into the stenotic vessels. The knowledge that neointimal formation can result in restenosis after stent implantation led to the development of drug-eluting stents (DES) which require long lasting antiplatelet therapy to avoid thrombotic complications. In the last years, the drug-eluting balloon (DEB) technology has emerged as an alternative option for the treatment of coronary and peripheral arteries. Clinical studies demonstrated the safety and effectiveness of DEB in various clinical scenarios and support the use of paclitaxel-eluting balloons for the treatment of in-stent restenosis, of small coronary arteries and bifurcations lesions. The protocols of DEB studies suggest that the dual antiplatelet therapy with aspirin and clopidogrel of four weeks after DEB is safe and effective.

    We aimed to provide a quantitative analysis of the 1-year clinical outcomes of patients with multisystem coronary artery disease who were included in recent randomized trials of percutaneous coronary intervention with multiple stenting versus coronary artery bypass graft surgery. An individual patient database was composed of 4 trials (Arterial Revascularization Therapies Study, Stent or Surgery Trial, Argentine Randomized Trial of Percutaneous Transluminal Coronary Angioplasty Versus Coronary Artery Bypass Surgery in Multivessel Disease 2, and Medicine, Angioplasty, or Surgery Study 2) that compared percutaneous coronary intervention with multiple stenting (N = 1518) versus coronary artery bypass graft surgery (N = 1533). The primary clinical end point of this study was the combined incidence of death, myocardial infarction, and stroke at 1 year after randomization. Secondary combined end points included the incidence of repeat revascularization at 1 year. All analyses were based on the intention-to-treat principle. After 1 year of follow-up, 8.7% of patients randomized to percutaneous coronary intervention with multiple stenting versus 9.1% of patients randomized to coronary artery bypass graft surgery reached the primary clinical end point (hazard ratio 0.95 and 95% confidence interval 0.74-1.2). Repeat revascularization procedures occurred more frequently in patients allocated to percutaneous coronary intervention with multiple stenting compared with coronary artery bypass graft surgery (18% vs 4.4%; hazard ratio 4.4 and 95% confidence interval 3.3-5.9). The percentage of patients who were free from angina was slightly lower after percutaneous coronary intervention with multiple stenting than after coronary artery bypass graft surgery (77% vs 82%; P = .002). One year after the initial procedure, percutaneous coronary intervention with multiple stenting and coronary artery bypass graft surgery provided a similar degree of protection against death, myocardial

    Objective Prior studies examining coronary atherosclerosis in the young have been limited by retrospective analyses in small cohorts. We examined the relationship between cardiovascular risk factors (RFs) and prevalence and severity of coronary atherosclerosis in a large, prospective, multinational registry of consecutive young individuals undergoing coronary computerized tomographic angiography (CCTA). Method and results Of 27 125 patients undergoing CCTA, 1635 young (<45 years) individuals without known coronary artery disease (CAD) or coronary anomalies were identified. Coronary plaque was assessed for any CAD, obstructive CAD (≥50% stenosis), and presence of calcified plaque (CP) and non-calcified plaque (NCP). Among 1635 subjects (70% men, age 38 ± 6 years), any CAD, obstructive CAD, CP, and NCP were observed in 19, 4, 5, and 8%, respectively. Compared with women, men demonstrated higher rates of any CAD (21 vs. 12%, P < 0.001), CP (6 vs. 3%, P = 0.01), and NCP (9 vs. 5%, P = 0.008), although no difference was observed for rates of obstructive CAD (5 vs. 4%, P = 0.46). Any CAD, obstructive CAD, and NCP were higher for young individuals with diabetes, hypertension, dyslipidaemia, current smoking, or family history of CAD; while only diabetes and dyslipidaemia were associated with CP. Increasing cardiovascular RFs was associated with a greater prevalence and extent and severity of CAD, with individuals with 0, 1, 2, ≥3 RFs manifesting a dose–response increase in any CAD (P < 0.001, for trend), obstructive CAD (P < 0.001, for trend), NCP (P < 0.001, for trend), and CP (P < 0.001, for trend). In multivariable analysis adjusting for sex and cardiovascular RFs, male sex was the strongest predictor for any CAD (odds ratio [OR] = 1.95, 95% confidence interval [CI] = 1.43–2.66, P < 0.001), CP (OR = 1.46, 95% CI = 1.08–1.98, P = 0.01), and NCP (OR = 1.33, 95% CI = 1.06–1.67, P = 0.01); family history of CAD was the strongest predictor for obstructive CAD

    Full Text Available The management of antithrombotic therapy in atrial fibrillation patients presenting with acute coronary syndrome and/or undergoing percutaneous coronary inter vention/stenting cannot be done according to a regimented common protocol, and stroke and bleeding risk stratification schema should be employed to individualize treatment options. A delicate balance is needed between the prevention of thromboembolism, against recurrent cardiac ischemia or stent thrombosis, and bleeding risk. New guidance from a consensus document of the European Society of Cardiology Working Group on Thrombosis, endorsed by the European Heart Rhythm Association and the European Association ofPercutaneous Cardiovascular Interventions on the management of Antithrombotic Therapy in Atrial Fibrillation Patients Presenting with Acute Coronary Syndrome and/or Undergoing Percutaneous Coronary Intervention/Stenting has sought to clarify some of the major issues and problems surrounding this practice, and will allow clinicians to make much more informed decisions when faced with treating such patients.

    Full Text Available Juan F Granada1, Barbara A Huibregtse2, Keith D Dawkins21The Jack H Skirball Center for Cardiovascular Research, Cardiovascular Research Foundation, Columbia University Medical Center, New York, NY, USA; 2Boston Scientific Corporation, Natick, MA, USAAbstract: Patients with diabetes mellitus, of female gender, increased age, and/or with peripheral vascular disease often develop coronary stenoses in small caliber vessels. This review describes treatment of these lesions with the paclitaxel-eluting 2.25 mm TAXUS® Liberté® Atom™ stent. Given the same stent composition, polymer, antirestenotic drug (paclitaxel, and release kinetics as the first-generation 2.25 mm TAXUS® Express® Atom™ stent, the second-generation TAXUS Liberté Atom stent incorporates improved stent design characteristics, including thinner struts (0.0038 versus 0.0052 inches, intended to increase conformability and deliverability. In a porcine noninjured coronary artery model, TAXUS Liberté Atom stent implantation in small vessels demonstrated complete strut tissue coverage compared with the bare metal stent control, suggesting a similar degree of tissue healing between the groups at 30, 90, and 180 days. The prospective, single-armed TAXUS ATLAS Small Vessel trial demonstrated improved instent late loss (0.28 ± 0.45 versus 0.84 ± 0.57 mm, P < 0.001, instent binary restenosis (13.0% versus 38.1%, P < 0.001, and target lesion revascularization (5.8% versus 17.6%, P < 0.001 at nine months with the TAXUS Liberté Atom stent as compared with the bare metal Express stent control, with similar safety measures between the two groups. The TAXUS Liberté Atom also significantly reduced nine-month angiographic rates of both instent late loss (0.28 ± 0.45 versus 0.44 ± 0.61 mm, P = 0.03 and instent binary restenosis (13.0% versus 25.9%, P = 0.02 when compared with the 2.25 mm TAXUS Express Atom control.

    Objective We studied the characteristics of patients with ST segment elevation myocardial infarction (STEMI) after expansion of a STEMI registry as part of the STEMI network programme in a metropolitan city and the surrounding area covering ∼26 million inhabitants. Design Retrospective cohort study. Setting Emergency department of 56 health centres. Participants 3015 patients with acute coronary syndrome, of which 1024 patients had STEMI. Main outcome measure Characteristics of reperfusion therapy. Results The majority of patients with STEMI (81%; N=826) were admitted to six academic percutaneous coronary intervention (PCI) centres. PCI centres received patients predominantly (56%; N=514) from a transfer process. The proportion of patients receiving acute reperfusion therapy was higher than non-reperfused patients (54% vs 46%, p<0.001), and primary PCI was the most common method of reperfusion (86%). The mean door-to-device (DTD) time was 102±68 min. In-hospital mortality of non-reperfused patients was higher than patients receiving primary PCI or fibrinolytic therapy (9.1% vs 3.2% vs 3.8%, p<0.001). Compared with non-academic PCI centres, patients with STEMI admitted to academic PCI centres who underwent primary PCI had shorter mean DTD time (96±44 min vs 140±151 min, p<0.001), higher use of manual thrombectomy (60.2% vs13.8%, p<0.001) and drug-eluting stent implantation (87% vs 69%, p=0.001), but had similar use of radial approach and intra-aortic balloon pump (55.7% vs 67.2%, and 2.2% vs 3.4%, respectively). In patients transferred for primary PCI, TIMI risk score ≥4 on presentation was associated with a prolonged door-in to door-out (DI-DO) time (adjusted OR 2.08; 95% CI 1.09 to 3.95, p=0.02). Conclusions In the expanded JAC registry, a higher proportion of patients with STEMI received reperfusion therapy, but 46% still did not. In developing countries, focusing the prehospital care in the network should be a major focus of care to improve the DI

    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.

    Dipyridamole-loading {sup 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 {sup 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 {sup 99m}Tc-tetrofosmin myocardial SPECT. (author)

    Full Text Available Background: Acute Coronary Syndrome (ACS is a shift manifestations pattern of ischemic myocardium. 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.

    Objectives To evaluate the prognostic value of the coronary artery calcium (CAC) score in patients with stable angina pectoris (SAP) who underwent percutaneous coronary intervention (PCI). Methods A total of 334 consecutive patients with SAP who underwent first PCI following multi-slice computer tomography (MSCT) were enrolled from our institution between January 2007 and June 2012. The CAC score was calculated according to the standard Agatston calcium scoring algorithm. Complex PCI was defined as use of high pressure bal-loon, kissing balloon and/or rotablator. Procedure-related complications included dissection, occlusion, perforation, no/slow flow and emer-gency coronary artery bypass grafting. Main adverse cardiac events (MACE) were defined as a combined end point of death, non-fatal myo-cardial infarction, target lesion revascularization and rehospitalization for cardiac ischemic events. Results Patients with a CAC score>300 (n=145) had significantly higher PCI complexity (13.1%vs. 5.8%, P=0.017) and rate of procedure-related complications (17.2%vs. 7.4%, P=0.005) than patients with a CAC score≤300 (n=189). After a median follow-up of 22.5 months (4-72 months), patients with a CAC score≤300 differ greatly than those patients with CAC score>300 in cumulative non-events survival rates (88.9 vs. 79.0%, Log rank 4.577, P=0.032). After adjusted for other factors, the risk of MACE was significantly higher [hazard ratio (HR):4.3, 95%confidence inter-val (95%CI):2.4-8.2, P=0.038] in patients with a CAC score>300 compared to patients with a lower CAC score. Conclusions The CAC score is an independent predictor for MACE in SAP patients who underwent PCI and indicates complexity of PCI and proce-dure-related complications.

    Background Omeprazole, usually used in the antiplatelet therapy during percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS), has been reported to increase ischemic events in retrospective studies. However, other clinical trials gave paradoxical results. The aim of this study was to assess the effects of omeprazole on clopidogrel efficacy and clinical events.Methods All patients (n=172) received aspirin (loading dose 300 mg and maintenance dose 100 mg/d) and clopidogrel (loading dose 600 mg and maintenance dose 75 mg/d) during the therapy. They were randomized to receive omeprazole (20 mg/d) or placebo for 30 days. Residual platelet activities in the adenosine 5'-diphosphate (ADP) pathway were detected on the fifth day after PCI with thrombelastography (TEG)-mapping. The clinical events were recorded after one month.Results According to the five levels of platelet activities, the frequency distributions of the inhibition rates were significantly different (P=0.0062). However, no significant change was seen in the distribution among the highest or the lowest inhibiting levels (>95% and <30% inhibition rate). And there were no significant differences (P >0.05) in events incidence, while gastra-intesternal bleeding decreased in co-administration of omeprazole.Conclusions Omeprazole significantly blunts clopidogreal efficacy while not exacerbates ischimic events in ACS undergoing PCI. Omeprazaole even can decrease gastra-intestinal bleeding in those patients.

    Full Text Available Background: Small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. Nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion. The aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter side branches with respect to bare metal vs. drug-eluting stents immediately after their deployment.Methods: This prospective bi-center study, conducted between June 2005 and January 2007, enrolled 82 patients treated with ≥1 of two stents (TAXUSTM LiberteTM or LiberteTM. Side branches ≥0.5 and <1.5 mm in diameter arising from the main vessel at the lesion site were evaluated. Results: Thirty-eight patients were treated with 42 LiberteTM stents (58 side branches and forty-four patients with 50 TAXUSTM LiberteTM (102 side branches. The rate of small side branch occlusion was 35.3% (36 in the TAXUSTM LiberteTM group compared to 29.31% (15 in the LiberteTM group (P-value= 0.7. The presence of type 1 side branch morphology (Lefevre classification was the most powerful predictor of small side branch occlusion (P-value=0.03. Conclusion: This study shows that drug-eluting stents are not inferior to bare metal stents as regards small side branch occlusion during coronary stenting

    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.

    Background As an adipocytokine,resistin has been proposed as a link between inflammation,metabolic disorder and atherosclerosis.The aim of the study is to evaluate whether serum resistin is associated with acute coronary syndrome (ACS) and major adverse cardiovascular events (MACEs) among postmenopausal women with ACS undergoing percutaneous coronary intervention (PCI).Methods A total of 106 consecutive postmenopausal women who underwent coronary angiography for evaluation of suspected myocardial ischemia were enrolled.Pre-procedure serum resistin,inflammatory and metabolic biomarkers were measured.All participants were followed for seven years for MACEs,including cardiovascular death,recurrent nonfatal myocardial infarction,and re-PCI.Results Patients with ACS (n=69) had significantly higher resistin levels than those without coronary artery disease (CAD) (n=37) (4.61 (1.79-10.80) ng/ml vs.2.36 (0.85-4.15) ng/ml,P=0.002).Correlation analysis revealed positive correlations between resistin levels and inflammatory and metabolic factors (P <0.05).A follow-up of a mean of 83.4months showed that patients with ACS suffered more MACEs than those without (13.0% vs.2.7%,P=0.05).Adjusted for cardiovascular risks,inflammatory and metabolic factors,multiple Logistic regression analysis indicated that an elevated resistin level was an independent predictor of ACS onset (OR=1.139,95% CI 1.024-1.268,P=0.017) and of MACEs after PCI (OR=1.099,95% CI 1.015-1.189,P=0.019).To clarify the association between resistin levels and MACEs,ACS patients were divided into two subgroups on the basis of resistin levels.Compared with the low resistin subgroup (≤4.35ng/ml,n=32),patients in the high resistin subgroup (>4.35 ng/ml,n=37) were more prone to suffer MACEs (21.6% vs.3.1%,P=0.015).Kaplan-Meier analysis showed a significantly lower event-free survival rate in ACS patients with high resistin levels than in the low resistin subgroup (78.4% vs.96.9%,Log rank 5.594,P=0

    Full Text Available Abstract Background Cardiovascular magnetic resonance (CMR has favorable characteristics for diagnostic evaluation and risk stratification of patients with known or suspected CAD. CMR utilization in CAD detection is growing fast. However, data on its cost-effectiveness are scarce. The goal of this study is to compare the costs of two strategies for detection of significant coronary artery stenoses in patients with suspected coronary artery disease (CAD: 1 Performing CMR first to assess myocardial ischemia and/or infarct scar before referring positive patients (defined as presence of ischemia and/or infarct scar to coronary angiography (CXA versus 2 a hypothetical CXA performed in all patients as a single test to detect CAD. Methods A subgroup of the European CMR pilot registry was used including 2,717 consecutive patients who underwent stress-CMR. From these patients, 21% were positive for CAD (ischemia and/or infarct scar, 73% negative, and 6% uncertain and underwent additional testing. The diagnostic costs were evaluated using invoicing costs of each test performed. Costs analysis was performed from a health care payer perspective in German, United Kingdom, Swiss, and United States health care settings. Results In the public sectors of the German, United Kingdom, and Swiss health care systems, cost savings from the CMR-driven strategy were 50%, 25% and 23%, respectively, versus outpatient CXA. If CXA was carried out as an inpatient procedure, cost savings were 46%, 50% and 48%, respectively. In the United States context, cost savings were 51% when compared with inpatient CXA, but higher for CMR by 8% versus outpatient CXA. Conclusion This analysis suggests that from an economic perspective, the use of CMR should be encouraged as a management option for patients with suspected CAD.

    Sixty years old male with severe rheumatic mitral stenosis (MS), presented with dyspnoea New York Heart Association (NHYA) class III to IV. Coronary angiogram revealed severe occlusive coronary artery disease in left anterior coronary artery (LAD). Percutaneous Transvenous Mitral Commissurotomy (PTMC) and Percutaneous Coronary Intervention (PCI) of Left Anterior Descurery (LAD) were done in same sitting. Both procedures were successful and ended without complication. After, half an hour while shifting to coronary care unit (CCU) patient developed cardiac tamponade, which was managed successfully. Patient was followed up for three month, he is doing well and recent echocardiogram showed mild mitral stenosis with normal left ventricular function. This case demonstrates the feasibility of the combined appliance on interventional techniques in selected patients as an alternative to cardiac surgery.

    Clinical presentation of takotsubo syndrome (TTS) mimics acute coronary syndrome (ACS) and does not allow differentiation. We aimed to develop a clinical score to estimate the probability of TTS and to distinguish TTS from ACS in the acute stage. Patients with TTS were recruited from the International Takotsubo Registry ( www.takotsubo-registry.com) and ACS patients from the leading hospital in Zurich. A multiple logistic regression for the presence of TTS was performed in a derivation cohort (TTS, n = 218; ACS, n = 436). The best model was selected and formed a score (InterTAK Diagnostic Score) with seven variables, and each was assigned a score value: female sex 25, emotional trigger 24, physical trigger 13, absence of ST-segment depression (except in lead aVR) 12, psychiatric disorders 11, neurologic disorders 9, and QTc prolongation 6 points. The area under the curve (AUC) for the resulting score was 0.971 [95% confidence interval (CI) 0.96-0.98] and using a cut-off value of 40 score points, sensitivity was 89% and specificity 91%. When patients with a score of ≥50 were diagnosed as TTS, nearly 95% of TTS patients were correctly diagnosed. When patients with a score ≤31 were diagnosed as ACS, ∼95% of ACS patients were diagnosed correctly. The score was subsequently validated in an independent validation cohort (TTS, n = 173; ACS, n = 226), resulting in a score AUC of 0.901 (95% CI 0.87-0.93). The InterTAK Diagnostic Score estimates the probability of the presence of TTS and is able to distinguish TTS from ACS with a high sensitivity and specificity. NCT0194762. © 2016 The Authors.

    The aim was to investigate the perioperative risk of ischaemic and bleeding events in patients with coronary stents undergoing cardiac and non-cardiac surgery and how these outcomes are affected by the perioperative use of oral antiplatelet therapy. This was a multicentre, retrospective, observational study conducted in patients with coronary stent(s) undergoing cardiac or non-cardiac surgery. The primary efficacy endpoint was the 30-day incidence of major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction (MI) or stroke. The primary safety endpoint was the 30-day incidence of Bleeding Academic Research Consortium (BARC) bleeding ≥ 2. A total of 666 patients were included. Of these, 371 (55.7 %) discontinued their antiplatelet medication(s) (all or partly) before undergoing surgery. At 30 days, patients with perioperative discontinuation of antiplatelet therapy experienced a significantly higher incidence of MACE (7.5 % vs 0.3 %, pantiplatelet discontinuation was the strongest independent predictor of 30-day MACE (odds ratio [OR]=25.8, confidence interval [CI]=3.37-198, p=0.002). Perioperative aspirin (adjusted OR 0.27, 95 % CI 0.11-0.71, p=0.008) was significantly associated with a lower risk of MACE. The overall incidence of BARC ≥ 2 bleeding events at 30-days was significantly higher in patients who discontinued oral antiplatelet therapy (25.6 % vs 13.9 %, pantiplatelet discontinuation was not independently associated with BARC ≥ 2 bleeding. In conclusion antiplatelet discontinuation increases the 30-day risk of MACE, in patients with coronary stents undergoing cardiac and non-cardiac surgery, while not offering significant protection from BARC≥ 2 bleeding.

    Background Transradial approach, which is now widely used in coronary angiography and intervention, may be advantageous with respect to the femoral access due to the lower incidence of vascular complications. Transulnar approach has been proposed for elective procedures in patients not suitable for transradial approach. The objective of this study was to evaluate the safety and efficacy of the transulnar approach versus the transradial approach for coronary angiography and intervention.Methods Two hundred and forty patients undergoing coronary angiography, followed or not by intervention, were randomized to transulnar (TUA) or transradial approach (TRA). Doppler ultrasound assessments of the forearm vessels were scheduled for all patients before procedures, 1 day and 30 days after procedures. The primary end point was access site vascular complications during hospitalization and 30 days follow-up. Major adverse cardiac events (MACE) as secondary end point was recorded till 30 days follow-up.Results Successful puncture was achieved in 98.3% (118/120) of patients in the TUA group, and in 100% (120/120) of patients in the TRA group. Coronary angiographies were performed in 40 and 39 patients in TUA and TRA group. Intervention procedures were performed in 78 and 83 patients in TUA and TRA group, respectively. The incidence of artery stenosis 1 day and 30 days after procedures was 11.0% vs. 12.3% and 5.1% vs. 6.6% in TUA and TRA group, respectively. Asymptomatic access site artery occlusion occurred in 5.1% vs.1.7% of patients 1 day and 30 days after transulnar angioplasty, and in 6.6% vs. 4.9% of patients 1 day and 30 days after transradial angioplasty. Minor bleeding was still observed at the moment of the ultrasound assessment in 5.9% and 5.7% of patients in TUA and TRA group, respectively (P=0.949). No big forearm hematoma, and A-V fistula were observed in both groups. Freedom from MACE at 30 days follow-up was observed in all patients.Conclusions The transulnar

    A 38-year-old man admitted to emergency department with 2 h of typical substernal chest pain, shortness of breath and nausea. The ECG revealed sinus rhythm with a 3 mm ST elevation in precordial leads V1-V6. The coronary angiography revealed acute total occlusion in left anterior descending artery (LAD) with normal circumflex and right coronary artery (RCA) along with bilateral fistulas arising from the proximal LAD and ostial RCA draining into the main pulmonary artery. Therefore, primary percutaneous coronary intervention and bare metal stent implantation was performed to culprit LAD lesion. The electrocardiographically gated 64-slice multidetector-row CT showed two large, tortuous abnormal vessels which arose from the both ostial part of the RCA and LAD draining into the main pulmonary artery. We report an unusual case of bilateral coronary artery to pulmonary artery fistulas leading to acute anterior myocardial infarction in a middle-aged male patient.

    Percutaneous coronary intervention (PCI), especially coronary stent implantation, has been shown to be an effective treatment for coronary artery disease. However, in-stent restenosis is one of the longstanding unsolvable problems following PCI. Although stents implanted inside narrowed vessels recover normal flux of blood flows, they instantaneously change the wall shear stress (WSS) distribution on the vessel surface. Improper stent implantation positions bring high possibilities of restenosis as it enlarges the low WSS regions and subsequently stimulates more epithelial cell outgrowth on vessel walls. To optimize the stent position for lowering the risk of restenosis, we successfully established a digital three-dimensional (3-D) model based on a real clinical coronary artery and analysed the optimal stenting strategies by computational simulation. Via microfabrication and 3-D printing technology, the digital model was also converted into in vitro microfluidic models with 3-D micro channels. Simultaneously, physicians placed real stents inside them; i.e., they performed “virtual surgeries”. The hydrodynamic experimental results showed that the microfluidic models highly inosculated the simulations. Therefore, our study not only demonstrated that the half-cross stenting strategy could maximally reduce restenosis risks but also indicated that 3-D printing combined with clinical image reconstruction is a promising method for future angiocardiopathy research.

    Although metallic coronary stents significantly reduce angina pectoris compared with optimal medical therapy, angina after percutaneous coronary intervention (PCI) remains frequent. We, therefore, sought to compare the incidence of any angina during the 1 year after PCI among the spectrum of commercially available metallic stents. Metallic stent type was classified as bare metal stent, Cypher, Taxus Express, Xience V, Promus Element, and Resolute. The primary end point was patient-reported angina within 1 year of PCI. Multivariable logistic regression was performed to assess the independent association of stent type with any angina at 1 year. Overall, 8,804 patients were queried in regard to angina symptoms; 32.3% experienced angina at some point in the first year after PCI. Major adverse cardiovascular events, a composite of all-cause mortality, target vessel revascularization, and Q-wave myocardial infarction, increased with angina severity: 6.8% for patients without angina, 10.0% for patients with class 1 or 2 angina, and 19.7% for patients with class 3 or 4 angina (p angina at 1 year after PCI. Baseline Canadian Cardiovascular Society class 3 or 4 angina, history of coronary artery bypass grafting, and history of PCI were associated with a higher likelihood of angina at 1 year; increasing age, male gender, presentation with acute coronary syndrome, and higher stented length were associated with less angina. In conclusion, metallic stent type is not associated with the occurrence of angina at up to 1 year after PCI.

    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

    Adverse cardiac events have been reported in patients waiting for either coronary surgery or angioplasty. However, data on the risk of adverse events while awaiting coronary angiography are limited, and none are available from a US population. To quantify cardiac outcomes in patients waiting for elective coronary angiography. Observational cohort study of 381 adult outpatients (mean [SD] age, 55 [12] years; 64% male; 61% white) on a waiting list for coronary angiography at a US tertiary care public teaching hospital during 1993-1994. Rates of cardiac death, nonfatal myocardial infarction, and hospitalizations for unstable angina or heart failure as a function of amount of time spent on a waiting list. Sixty-six patients were dropped from the waiting list but were included in the study analysis. During a mean (SD) follow-up of 8.4 (6.5) months, cardiac death, myocardial infarction, and hospitalization occurred in 6 (1.6%), 4 (1.0%), and 26 (6.8%) patients, respectively. The probability of events was minimal in the first 2 weeks and increased steadily between 3 and 13 weeks. By Cox multivariate analysis, 2 variables independently identified an increased risk of adverse events: a strongly positive treadmill exercise electrocardiogram or positive stress imaging result at referral (odds ratio [OR], 2.32; 95% confidence interval [CI], 1.22-4.16; P=.01) and the use of 2 to 3 anti-ischemic medications (OR, 1.98; 95% CI, 1.19-3.96; P=.04). Among 311 patients who ultimately underwent angiography, those with adverse events had a higher prevalence of coronary disease (96% vs 60%; P<.001), more frequently required revascularization (93% vs 53%; P<.001), and had longer hospital stays (mean [SD], 6.2 [4.3] vs 1.3 [0.7] days; P=.001). Our data suggest that in a cohort referred for coronary angiography, delaying the procedure places some patients at risk for death, myocardial infarction, unplanned hospitalization, a longer hospital stay, and, potentially, a poorer prognosis.

    Risk-factor modification after an acute coronary event is imperative, and intervention strategies are continuously being developed to assist patients with behavioral change and, consequently, decreasing the risk of further coronary episodes. This article describes the development of the health-related lifestyle self-management (HeLM) intervention, which is a brief structured intervention embedded within the transtheoretical model of behavioral change. The HeLM intervention was developed by undertaking three discrete yet interrelated studies and consisted of the following components: goal-setting, the HeLM booklet, feedback regarding personal risk, team-building and communication with the patient's family physician, three supportive telephone calls, trained interviewers, a refrigerator magnet, and a health diary for self-monitoring. The HeLM intervention has been successfully implemented in 50 patients with acute coronary syndrome after discharge from hospital and has been demonstrated to be feasible and practical and could easily be delivered by health care professionals.

    Supported by growing evidence from randomized clinical trials and observational or registry studies,percutaneous coronary intervention (PCI) with implantation of drug-eluting stents (DES) has become the standard of care for coronary artery disease,because of reduced repeat intervention and improved clinical outcomes in comparison with bare metal stent.1-3Currently,majority of coronary artery disease patients with complicated lesion subsets or clinical conditions can be successfully treated with DES-based PCI with favorable results.4-6 In 2011,around 300000 PCI procedures have been performed in China,with the penetration rate of DES reaching beyond 90% in most of the centers.

    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.

    Aims Comparison of magnetic guidewire navigation in percutaneous coronary intervention (MPCI) vs. conventional percutaneous coronary intervention (CPCI) for the treatment of acute myocardial infarction. Methods and results We compared 65 sequential patients (mean age 61 ± 15 years) undergoing primary MPCI with those of 405 patients undergoing CPCI (mean age 61 ± 13 years). The major endpoint was contrast media use. Technical success and procedural outcomes were evaluated. Clinical demographics and angiographic characteristics of the two groups were similar, except for fewer patients with previous coronary artery bypass grafting (CABG) and hypertension in the CPCI group and fewer patients with diabetes in the MPCI group. The technical success rate was high in both the MPCI and CPCI groups (95.4 vs. 98%). There was significantly less contrast media usage in the MPCI compared with the CPCI group, median reduction of contrast media of 30 mL with an OR = 0.41 (0.21-0.81). Fluoroscopy times were significantly reduced for MPCI compared with CPCI, median reduction of 7.2 min with an OR = 0.42 (0.20-0.79). Conclusion This comparison indicates the feasibility and non-inferiority of magnetic navigation in performing primary PCI and suggests the possibility of reductions in contrast media use and fluoroscopy time compared with CPCI.

    Although statin therapy is essential for secondary cardiovascular prevention, the therapeutic effect of statins on cardiovascular outcomes in patients with advanced chronic kidney disease (CKD) after coronary revascularization has not been fully elucidated. In the CREDO-Kyoto Registry Cohort-2, 14,706 patients who underwent first coronary revascularization were divided into 4 strata based on estimated glomerular filtration rate (eGFR) or status of hemodialysis (HD). Patients in each stratum were further divided into 2 groups based on statin therapy at discharge: non-CKD stratum (eGFR ≥60 ml/min/1.73 m(2)), 8,959 patients (statin, n = 4,747; no statin, n = 4,212); mild CKD stratum (eGFR ≥30 to <60 ml/min/1.73 m(2)), 4,567 patients (statin, n = 2,135; no statin, n = 2,432); severe CKD stratum (eGFR <30 ml/min/1.73 m(2)), 608 patients (statin, n = 229; no statin, n = 379); and HD stratum, 572 patients (statin, n = 117; no statin, n = 455). Median follow-up duration was 956 days (interquartile range 699 to 1,245). Adjusted risk for major adverse cardiovascular events (MACEs; composite of cardiovascular death, myocardial infarction, or stoke) was significantly lower in the statin group than in the no-statin group in the non-CKD (hazard ratio 0.8, 95% confidence interval 0.68 to 0.95, p = 0.01) and mild CKD (hazard ratio 0.69, 95% confidence interval 0.56 to 0.84, p = 0.0002) strata. However, a significant association of statin therapy and lower risk for MACEs was not seen in the severe CKD (hazard ratio 0.91, 95% confidence interval 0.6 to 1.38, p = 0.65) and HD (hazard ratio 1.04, 95% confidence interval 0.64 to 1.69, p = 0.87) strata. In conclusion, statin therapy was associated with significantly lower risk for MACEs in patients with non-CKD and mild CKD undergoing coronary revascularization. However, therapeutic benefits of statins were not apparent in patients with severe CKD and HD.

    High blood glucose in patients with acute coronary syndromes have been associated with adverse short-term outcomes in patients without diabetes. However, the relation of admission glucose to long-term outcomes in these patients was less well established. Accordingly, consecutive patients with ST-elevation myocardial infarction (STEMI) without diabetes enrolled at 155 sites from July 2000 to November 2002 in the ACOS Registry were evaluated. Patients were categorized into tertiles based on admission blood glucose. Clinical end points of interest were 1-year mortality and composite of death, reinfarction, stroke, or rehospitalization (major adverse cardiac clinical events [MACCEs]) in the hospital and after discharge. Of 5,866 patients with STEMI, 36.9% had blood glucose 150 mg/dl. Admission blood glucose was significantly related to increased risk of not only in-hospital events (death, glucose >150 vs 150 vs 150 vs 150 vs <120 mg/dl, adjusted OR 1.31, 95% CI 1.00 to 1.71, p <0.0001). In conclusion, high blood glucose at admission to the hospital independently correlated with short- and midterm mortality in patients with STEMI.

    Background To investigate the effects of collateral coronary circulation on the outcome of the patients with anterior myocardial infarction (NII) with left anterior desending artery occlusion abruptly.Methods Data of 189 patients with acute anterior MI who had a primacy percutaneous coronary intervention (PCI) in the fast 12 h from the onset of symptoms between January 2004 and December 2008 were retrospective analyzed.Left anterior descending arteries (LAD) of all patients were occluded.LADs were reopened with primary PCL According to the collateral circulation,all patients were classified to two groups:no collateral group (n=111),patients without angiographic collateral filling of LAD or side branches (collateral index 0) and collateral group (n=78),and patients with angiographic collateral filling of LAD or side branches (collateral index 1,2 or 3).At one year's follow-up,the occurrence of death,reinfarction,stent thrombosis (ST),target vessel revascularization and readmission because of heart failure were observed.Results At one year,the mortality was lower in patients with collateral circulation compared with those without collateral circulation (1% vs.8%,P=0.049),whereas there were no differences in the occurrence of reinfarction,ST,target vessel revascularization and readmission because of heart failure.The occurrence of composite of endpoint was lower in patients with collateral circulation compared with those without collateral circulation (12% vs.26%; P=0.014).Conclusions Pre-exist collateral circulation may prefigure the satisfactory prognosis to the patients with acute anterior MI after primary PCI in the fast 12 h of MI onset.

    There is general consensus that emergency percutaneous coronary intervention (PCI) is the preferred treatment for patients with ST-elevation myocardial infarction (STEMI), so long as it can be delivered in a timely fashion, by an experienced' operator and cardiac catheterization laboratory (CCL) team. STEMI is both a functional and structural issue. Although it has been recognized since the work of pioneering cardiologists and surgeons in Spokane, Washington, that approximately 88% of patients presenting within 6 hours of onset of STEMI have an occluded coronary artery, it is the pathophysiology of myocardial necrosis, and the varied consequences of necrosis that characterize STEMI. Accordingly, experience' of both primary operator and cardiac catheterization laboratory (CCL) crew, in performing an emergency PCI for STEMI, are as much a function of experience with the treatment of complex MI patients, as experience with coronary intervention. Rapidly achieving normal coronary artery flow, at both the macro and micro vascular levels, is the recognized key to aborting the otherwise progressive wavefront' of myocardial necrosis. The time urgency of decisions (Time is muscle') make emergency PCI for patients with on-going necrosis, more like emergency room (ER) care, than like most in-hospital or outpatient care. In general, most patients with acute coronary syndromes (ACS) are currently thought to have plaque rupture and/or erosion with subsequent thrombosis and embolization. Consequences of thrombo-embolism, such as slow flow' or no-reflow' are in addition to, the structural (anatomic) considerations of PCI in stable patients (such as ostial location; bifurcation involvement; heavy calcification; tortuosity of lesion or access to it; length of disease; caliber of infarct-artery; etc.). Good quality studies have provided strong support for the specific added value of glycoprotein IIb/IIIa inhibitors (especially abciximab), dual antiplatelet therapy (the addition of

    Background We aimed to carry out comparison of different bleeding avoidance strategies in doing primary percutaneous coronary intervention (PPCI) using either radial or femoral as access of choice and either bivalirudin or unfractionated heparin as anticoagulant of choice. In this analysis, we analyzed the influence of major bleeding definition on bleeding outcomes as well. Methods We did a retrospective analysis of 139 patients with ST-segment elevation myocardial infarction (STEMI) who had PPCI in our academic center from January 2010 till October 2013. The primary outcome at 30 days was a composite of death from any cause or stent thrombosis or non-coronary artery bypass grafting (CABG) related major bleeding (CathPCI Registry definition) and secondary outcomes were individual components of primary outcome and the hospital length of stay. Results There was no significant difference among different access/anticoagulant combinations with regards to primary outcome (22% in radial/bivalirudin vs. 5% in radial/heparin vs. 17% in femoral/bivalirudin vs. 28% in femoral/heparin group; p = 0.2) as well as its individual components except the hospital length of stay (2.56 vs. 3 vs. 3.97 vs. 4.4 days each; p definition, it went up to 25 % due to one particular component (p definition on bleeding outcomes.

    Data comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris. One hundred seventy-seven patients with significant coronary artery stenosis were randomly assigned to either the PCI group (n=90) or the OMT group (n=87). The primary outcome was a composite of major adverse events in the 1-year follow-up period that included cardiovascular death, non-fatal myocardial infarction, coronary revascularization, and stroke. Major adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death [hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041-5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039-4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057-14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106-0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035-0.703, p=0.016). Elective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT.

    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.

    To describe the contemporary treatment and outcomes for patients with angiographically confirmed (definite) stent thrombosis (ST). Limited data are available on contemporary treatment patterns and outcomes of patients with ST in the United States. In this multicenter California registry, consecutive cases of definite ST over 5 years were identified. Clinical characteristics, in-hospital outcomes, and long-term survival are reported. One hundred and sixty five consecutive episodes of ST were identified in 153 patients from January 2005 to February 2010. The distribution of acute (≤24 hr), subacute (24 hr to 30 days), late (30 days to 1 year), and very late (≥1 year) ST was 3.9%, 21.8%, 17.6%, and 50.3%, respectively. Only 41.2% of patients were on dual antiplatelet therapy at the time of presentation, while 22.4% of patients were on none. Of the 61.4% of patients treated with restenting, 71.1% of them received a drug-eluting stent. Procedural success was 88.1%, and in-hospital death, stroke, and CABG occurred in 5.5%, 0.6%, and 6.1% of subjects, respectively. All-cause mortality at 1 year was 14.3%. Although female gender, diabetes mellitus (DM), bifurcation disease, ejection fraction <40%, and cardiogenic shock at the time of presentation were associated with an increased risk of in-hospital mortality, only DM (P = 0.047) and bifurcation disease (P = 0.027) remained independent predictors of in-hospital death. In-hospital mortality from definite ST is lower than previously reported, but long-term mortality remains high. DM and bifurcation disease, but not type of percutaneous therapy, are independently associated with in-hospital mortality. Copyright © 2011 Wiley Periodicals, Inc.

    Multiple variations exist in performing a primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) among various cardiologists. These variations range from the choice of peripheral access artery (radial vs femoral), performance or time of complete angiography including left ventriculography, and nonculprit vessel angiography before or after intervening on the culprit vessel. The reasons for such variations include emphasis on door-to-balloon time, knowledge of cardiac anatomy before proceeding with pPCI, physician expertise, and the level of comfort with radial approach. Over the last 2 decades, the field of interventional cardiology has changed dynamically leading to marked improvements in the clinical outcomes of patients with STEMI. This includes upstreaming of pPCI along with technical advancements ranging from radial artery catheterization to culprit lesion-guided approach. Increased comfort with use of radial access approach by cardiologists and availability of multiuse guide catheters would both reduce door-to-balloon time and enable complete coronary angiography before performance of percutaneous coronary intervention. There are no clear guidelines or consensus dictating on cardiologists a correct sequence of action during STEMI, or even suggesting what the preferred approach is. Lack of guidelines results in a substantive variation in methodology. This review aims to highlight and to better understand the variations in the current practice, and to emphasize the advantages as well as the disadvantages of each approach. It is also perhaps a call out for guidelines that direct cardiologists to the best practice. Copyright © 2017 Elsevier Inc. All rights reserved.

    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.

However, there is no study evaluating the clinical differences between patients who have undergone temporary pacing (TP and patients who have not. The present study was designed to investigate whether TP has any prognostic significance in inferior STEMI complicated by complete AVB.Methods: From January 2009 to December 2014, 295 consecutive patients diagnosed with inferior wall STEMI in a university hospital were reviewed. All of them underwent primary percutaneous coronary intervention (PCI. Among the 295 patients, there were 72 patients with complete AVB. The clinical characteristics, procedural data, and long-term major adverse cardiocerebrovascular events were compared in patients with and without TP.Results: Baseline clinical and procedural characteristics were similar between patients with and without TP. Patients with TP were more likely to present with cardiogenic shock; thus, additional interventions were attempted via a femoral approach, as patients received further treatment with intra-aortic balloon pumps and were subjected to additional cardiopulmonary resuscitation. Most cases of complete AVB were primarily caused by right coronary artery occlusion. After a median follow-up period of 344 (range, 105.5–641 days, major adverse cardiocerebrovascular events did not differ between the groups (P=0.528.Conclusion: We conclude that primary PCI without TP is acceptable in complete AVB-complicated acute inferior STEMI. To avoid delay in reperfusion, we suggest that primary PCI should be the first priority therapy rather than treating

    The use of primary percutaneous coronary intervention (PCI) as the preferred reperfusion strategy in ST-elevation myocardial infarction (STEMI) requires optimal systems-of-care and logistics in order to enable rapid treatment of all patients. In Denmark, this has been achieved through prehospital...... electrocardiogram diagnosis, field triage and dedicated PCI centres 24/7. Today, primary PCI is an option for all Danish patients with STEMI, regardless of the distance to a PCI centre. This has led to a decline in both mortality and morbidity....

    Aggressive intravenous and oral dual antiplatelet therapy has established primary percutaneous coronary intervention (PCI) as the standard of care for acute myocardial infarction. Clopidogrel is currently the thienopyridine of choice for dual antiplatelet therapy in patients treated with PCI. The dose regime and duration of therapy of clopidogrel has undergone multiple refinements. Recently, 2 novel third generation oral inhibitors of P2Y12 receptors, prasugrel and ticagrelor, have undergone clinical evaluation with promising results. This article is a non-exhaustive review of the literature, concentrating on the role of current and novel oral antiplatelet agents for acute myocardial infarction particularly highlighting the limitations and issues associated with clopidogrel use.

    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.

    A 73-year-old male in a persistent vegetative state underwent percutaneous coronary intervention (PCI) for unstable angina with multiple-vessel stenosis. The maximum dose pharmaceutical therapy was ineffective in controlling his symptoms. The goal of the procedure was to alleviate the patient's severe chest pain and vomiting with minimal invasion and risk. The procedure was effective despite treating only the culprit artery. Symptoms disappeared immediately after PCI and the patient remained attack free for 12 months. With the consent of the patient's family and support of medical staff, elective single-vessel PCI can be a practical and effective treatment option for refractory angina in patients with impaired consciousness.

    An 82-year-old female patient undergoing cardiogenic shock caused by atrioventricular junctional rhythm immediately after percutaneous coronary intervention (PCI) is described. Pharmacotherapy was invalid, and subsequent application of atrial pacing reversed the cardiogenic shock. PCI-related injury of sinuatrial nodal artery leading to acute atrial contractility loss, accompanied by atrioventricular junctional arrhythmia, was diagnosed. We recommend that preoperative risk evaluation be required for multi-risk patients. Likewise, emergent measures should to be established in advance. This case reminds us that atrial pacing can be an optimal management technique once cardiogenic shock has occurred.

    Full Text Available Abstract Rationale There is growing evidence that obstructive sleep apnea is associated with coronary artery disease. However, there are no data on the course of coronary stenosis after percutaneous coronary intervention in patients with obstructive sleep apnea. Objectives To determine whether sleep apnea is associated with increased late lumen loss and restenosis after percutaneous coronary intervention. Methods 78 patients with coronary artery disease who underwent elective percutaneous coronary intervention were divided in 2 groups: 43 patients with an apnea hypopnea – Index 10/h (group II. Late lumen loss, a marker of restenosis, was determined using quantitative coronary angiography after 6.9 ± 3.1 months. Main results Angiographic restenosis (>50% luminal diameter, was present in 6 (14% of group I and in 9 (25% of group II (p = 0.11. Late lumen loss was significant higher in pt. with an AHI > 10/h (0.7 ± 0.69 mm vs. 0.38 ± 0.37 mm, p = 0.01. Among these 35 patients, 21(60% used their CPAP devices regularly. There was a marginally lower late lumen loss in treated patients, nevertheless, this difference did not reach statistical significance (0.57 ± 0.47 mm vs. 0.99 ± 0.86 mm, p = 0.08. There was no difference in late lumen loss between treated patients and the group I (p = 0.206. Conclusion In summary, patients with OSA and coronary artery disease have a higher degree of late lumen loss, which is a marker of restenosis and vessel remodeling after elective percutaneous intervention.

    Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease (CAD) after they have undergone percutaneous coronary intervention (PCI).The objective of this study is to evaluate the effect of myocardial perfusion by three different methods-intra-coronary myocardial contrast echocardiography (ICMCE),corrected thrombolysis in myocardial infarction frame count (CTFC),and coronary blood flow velocity (BFV)-and to determine the value of these different methods in the evaluation of the effect of myocardial perfusion post-PCI.For the study sixty-eight patients were divided into four groups based on selective coronary angiography results:group A (normal coronary artery),group B (75%-95% coronary artery stenosis),group C (coronary artery stenosis > 95%) and group D (acute total coronary occlusion).The effect of myocardial reperfusion was evaluated using the above mentioned three methods 15 min after PCI.IC-MCE was also performed before PCI in group D.The quantitative parameters of MCE involved:contrast peak intensity,time to peak intensity and area under the curve,representing myocardial blood volume,reperfusion velocity and myocardial blood flow,respectively.No difference was found in CTFC between the coronary artery stenosis group and the normal group.BFV was slower in group D than in group A (P < 0.05).The myocardial blood volume and the myocardial blood flow of the IC-MCE quantitative parameters were markedly lower in group C compared with those in group A (P < 0.05),and there were significant differences in the three MCE parameters between group D and group A (P < 0.05).For those patients with acute or total occlusion,the levels of myocardial perfusion before and after PCI were similar,as determined by IC-MCE and visually analyzed from 61 segments (P < 0.05).Quantitative IC-MCE evaluation of myocardial reperfusion is more accurate than with the other two methods.Moreover,with qualitative IC-MCE the level of

    Full Text Available Background: Controversy persists over the potential benefits/harms of opium consumption in coronary heart disease. This study investigated the association between 12 months' major adverse cardiac events (MACE and pre-procedural opium consumption among patients undergoing percutaneous coronary intervention (PCI.Methods: Retrospectively, 1545 consecutive men who underwent PCI between 21st  June 2009 and 20th June 2010 at Tehran Heart Center and were registered in the PCI Databank were entered into this cohort study. The occurrence of MACE, defined as cardiac death, non-fatal myocardial infarction, and need for target vessel revascularization (TVR or target lesion revascularization (TLR, was compared between two groups of opium consumers and non-consumers in 350 (22.7% patients. Results: Sixty-four (0.86% patients expired within 12 months. After adjustment for potential confounders, analysis revealed that opium consumption had no significant relationship with 12 months' MACE [11(3.1% vs. 53(4.4%; p value= 0.286, among opium users vs. non users, respectively].Furthermore, the different components of MACE, including target vessel revascularization, target lesion revascularization, coronary artery bypass graft, and non-fatal myocardial infarction, were not significantly related to opium use.Conclusion: Pre-procedural opium usage in patients undergoing PCI was not associated with 12 months' MACE.

    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.

    The research has been carried out in patients of TSMU Cardiovascular Department of A.Aladashvili University Clinic. 105 patients with acute myocardial infarction have been involved in the study, wich undergoing percutaneous coronary intervention (PCI). For several years coronary angioplasty has been proposed to be an effective method, but in spite of its well developed technique, probability of myocardial injury is still high which appears to have no clinical or electrocardiographic manifestations and is diagnosed only by elevation of cardiac marker level. According to our study data after successful PCI elevation of CK-MB mass was observed in 34.4% patients, majority of those patients had STEMI. In II group the age of patients was higher compared to I group. There were more patients with diabetes mellitus (38.8%), dyslipidemia (86.1%) and patients with low left ventricular ejection fraction (50%). Also there were more patients with previous MI and damage of 3 coronary arteries. Hence age, diabetes mellitus, dyslipidemia, left ventricular ejection fraction MB elevation after successful PCI. Solid elevation of CK-MB after procedure was also associated with increased hospital complications rate, 30-day and 6 months hospitalization rate and 6 months mortality rate. It should be noted that from 36 patients who developed solid (24 h) elevation of CK-MB after PCI CK-MB mass was increased in all cases, while the concentration was elevated only in 16 cases. It proves that CK-MB mass is more significant criteria of myocardial injury.

    Early menopause has been found to be associated with higher risk of cardiovascular disease. Our objective was to investigate the impact of early menopause on clinical outcomes for women undergoing percutaneous coronary intervention (PCI). We observed female patients with coronary artery disease (CAD) undergoing PCI and found that women with early menopause (≤46 years old) were more likely to have CAD risk factors and more severe coronary lesions. During the 18-month follow-up, early menopause was associated with similar risk of death and myocardial infarction but higher risk of target lesion revascularization (TLR; 7.8% vs 5.3%, P = .003) and major adverse cardiovascular events (MACEs; 11.3% vs 9.0%, P = .007). After adjustment, early menopause was an independent risk factor for 18-month MACEs (hazard ratio [HR], 1.54; 95% confidence interval [CI] 1.18-2.00) and TLR (HR 1.61; 95% CI 1.21-2.13). In conclusion, for women undergoing PCI, early menopause is associated with higher risk of MACE, which is mainly driven by risk of TLR. © The Author(s) 2015.

    The purpose of our study is to verify, whether percutaneous mitral annuloplasty results in reverse remodeling in patients with functional mitral regurgitation (FMR) and impaired ejection fraction (EF) and to investigate which echo parameters may help in prediction of the efficacy of the procedure. FMR exacerbates left ventricular (LV) dilatation and contributes to both LV remodeling and heart failure. We analyzed baseline and 1 month follow-up data in 22 consecutive patients with FMR, who underwent successful percutaneous trans-coronary venous mitral annuloplasty with the Carillon device. Significant reduction of FMR echo parameters, including vena contracta (VC), effective regurgitant orifice area (EROA), and regurgitant volume (RV) were observed and maintained throughout 1 month follow up and did not correlate with baseline annular, LV or with the left atrial diameters. Baseline mitral tenting area correlated negatively with the relative improvement (% difference) of EROA (r = -0.5898) and RV (r = -0.4363), but not with VC (r = 0.1341). In addition, increased EF as well as a significant reduction in left ventricular diameters were noted. The increase in EF negatively correlated with the change in EROA (r = -0.50058), PISA (r = -0.5327), and RV (r = -0.5457). Baseline mitral tenting area significantly correlated with the 1 month change in EF (r = 0.5946) and stroke volume (r = 0.6913). The improvement of FMR after treatment with the Carillon device is associated with LV reverse remodeling and an increase in systolic performance, that correlates with the reduction in mitral regurgitation, being not dependent on baseline heart diameters. Mitral tenting area seems to be an important parameter in prediction of benefit from percutaneous mitral annuloplasty. © 2016, Wiley Periodicals, Inc.

We sought to investigate whether OSA affects the clinical outcomes of patients undergoing PCI.Patients and methods: All enrolled individuals treated with PCI were evaluated for OSA by polysomnography. The primary end point was defined as major adverse cardiac events (MACEs at 2 years, including cardiac death, myocardial infarction (MI, and/or target vessel revascularization.Results: A total of 340 consecutive patients undergoing PCI were assigned to the OSA (n=152, apnea–hypopnea index ≥15 and non-OSA (n=188, apnea–hypopnea index <15 groups. The incidence of OSA in patients with coronary artery disease undergoing PCI was 44.7%. Patients in the OSA group had more three-vessel disease (34.9%, increased number of total implanted stents (3.3±2.0, and longer total stent length (83.8±53.1 mm when compared to the non-OSA group (23.4%, P=0.020; 2.8±1.9, P=0.007; 68.7±48.4, P=0.010. After a median follow-up of 2 years, the incidence of MACEs was significantly higher in patients with OSA (25.0% vs 16.0%, P=0.038, mainly driven by the increased periprocedural MI (19.2% vs 11.2%, P=0.038 in the OSA group. By Cox regression multivariable analysis, the independent predictor of MACEs was OSA (hazard ratio: 1.962, 95% confidence interval: 1.036–3.717, P=0.039.Conclusion: There was a high prevalence of moderate-to-severe OSA

    Full Text Available BACKGROUND: The efficacy of clopidogrel is inconclusive in the chronic kidney disease (CKD population with acute coronary syndrome (ACS. Furthermore, CKD patients are prone to bleeding with antiplatelet therapy. We investigated the efficacy and safety of clopidogrel in patients with ACS and CKD. METHODS: In a Taiwan national-wide registry, 2819 ACS patients were enrolled. CKD is defined as an estimated glomerular filtration rate of less than 60 ml/min per 1.73 m(2. The primary endpoints are the combined outcomes of death, non-fatal myocardial infarction and stroke at 12 months. RESULTS: Overall 949 (33.7% patients had CKD and 2660 (94.36% patients received clopidogrel treatment. CKD is associated with increased risk of the primary endpoint at 12 months (HR 2.39, 95% CI 1.82 to 3.15, p<0.01. Clopidogrel use is associated with reduced risk of the primary endpoint at 12 months (HR 0.42, 95% CI: 0.29-0.60, p<0.01. Cox regression analysis showed that clopidogrel reduced death and primary endpoints for CKD population (HR 0.35, 95% CI: 0.21-0.61 and HR 0.48, 95% CI: 0.30-0.77, respectively, both p<0.01. Patients with clopidogrel(-/CKD(-, clopidogrel(+/CKD(+ and clopidogrel(-/CKD(+ have 2.4, 3.0 and 10.4 fold risk to have primary endpoints compared with those receiving clopidogrel treatment without CKD (all p<0.01. Clopidogrel treatment was not associated with increased in-hospital Thrombolysis In Myocardial Infarction (TIMI bleeding in CKD population. CONCLUSION: Clopidogrel could decrease mortality and improve cardiovascular outcomes without increasing risk of bleeding in ACS patients with CKD.

    Full Text Available Abstract Background Studies have shown patients who are delayed for surgical cardiac revascularization are faced with increased risks of symptom deterioration and death. This could explain the observation that operative mortality among persons undergoing coronary artery bypass surgery (CABG is higher among women than men. However, in jurisdictions that employ priority wait lists to manage access to elective cardiac surgery, there is little information on whether women wait longer than men for CABG. It is therefore difficult to ascertain whether higher operative mortality among women is due to biological differences or to delayed access to elective CABG. Methods Using records from a population-based registry, we compared the wait-list time between women and men in British Columbia (BC between 1990 and 2000. We compared the number of weeks from registration to surgery for equal proportions of women and men, after adjusting for priority, comorbidity and age. Results In BC in the 1990s, 9,167 patients aged 40 years and over were registered on wait lists for CABG and spent a total of 136,071 person-weeks waiting. At the time of registration for CABG, women were more likely to have a comorbid condition than men. We found little evidence to suggest that women waited longer than men for CABG after registration, after adjusting for comorbidity and age, either overall or within three priority groups. Conclusion Our findings support the hypothesis that higher operative mortality during elective CABG operations observed among women is not due to longer delays for the procedure.

However, this finding has never been verified in the Chinese population. The present study analyzed two-year clinical outcomes after placement of coronary drug-eluting stents in Chinese men and women. Methods: From January 2005 to December 2010, a total of 3804 Chinese patients (2776 men, 1028 women who underwent drug-eluting stent implantation were studied prospectively. The primary endpoint was the composite major adverse cardiac event (MACE rate, including myocardial infarction, cardiac death, and target vessel revascularization at two years. Stent thrombosis served as the safety endpoint. Propensity score matching was used to compare the adjusted MACE rate between the two groups. Results: At two-year follow-up, unadjusted rates of myocardial infarction, non-ST segment elevation myocardial infarction, target vessel revascularization, and MACE were significantly different between men (6.84%, 4.6%, 13.1%, and 21.7%, respectively and women (3.8% [P = 0.001], 2.0% [P < 0.001] 10.3% [P = 0.025], and 16.3% [P < 0.001], respectively. After propensity score matching, there were no significant differences in composite MACE and individual endpoints at two years between the genders. Conclusion: Despite all the unfavorable risk factor clustering in

    Full Text Available Background: Percutaneous Coronary Intervention (PCI for bifurcated lesions is associated with a low rate of success and high rate of complications compared to such treatment of lesions of most other morphologies. Symptoms occurring at the time of procedure caused by PCI may require additional angiography with or without stenting through stent struts, which subsequently increases risks of restenosis and stent thrombosis. The purpose of this study was to evaluate the incidence of major side branch (>1mm complications during PCI and their clinical, angiographic, and interventional predictors. Methods: Of 104 consecutive patients, we evaluated 50 lesions with ostial stenosis (group 1 and 54 lesions without ostial stenosis (group 2 as a control group. Age, sex, major coronary artery disease risk factors, and left ventricular ejection fraction (LVEF, were compared between groups. Morphology, location, type of lesion, length of lesion, main and side branch diameters, interventional approach, and clinical and interventional outcomes were the main variables studied during this trial. Results: Side Branch Compromise (SBC occurred in 41 (39.4% of the total number of cases: 52% in group 1 and 27.8% in group 2 (p=0.01. More than 80% of SBC occurred in main branches with stenosis (p=0.02. SBC did not correlate with clinical characteristics, bifurcation location, LVEF, or stent number. Chest pain was reported in 18% of the cases during or after PCI. Three non Q wave myocardial infarctions (MI occurred after SBC, each with >2 mm branch diameters (p=0.02. SBC was not associated with adverse clinical outcomes. Conclusion: The risk of MI after losing the side branch of a bifurcation lesion is not usually as high as it is after losing the main branch. Furthermore, it may not be a serious problem as one of the problems of the bifurcation lesion is the high rate of post procedural non Q wave MI associated with SBC. These findings demonstrate that side branch ostial

    The aim of this review was to summarize the concept of appropriate use criteria (AUC) regarding percutaneous coronary intervention (PCI) and document AUC use and impact on clinical practice in Japan, in comparison with its application in the United States. AUC were originally developed to subjectively evaluate the indications and performance of various diagnostic and therapeutic modalities, including revascularization techniques. Over the years, application of AUC has significantly impacted patient selection for PCI in the United States, particularly in non-acute settings. After the broad implementation of AUC in 2009, the rate of inappropriate PCI decreased by half by 2014. The effect was further accentuated by incorporation of financial incentives (e.g., restriction of reimbursement for inappropriate procedures). On the other hand, when the United States-derived AUC were applied to Japanese patients undergoing elective PCI from 2008 to 2013, about one-third were classified as inappropriate, largely due to the perception gap between American and Japanese experts. For example, PCI for low-risk non-left atrial ascending artery lesion was more likely to be classified as appropriate by Japanese standards, and anatomical imaging with coronary computed tomography angiography was used relatively frequently in Japan, but no scenario within the current AUC includes this modality. To extrapolate the current AUC to Japan or any other region outside of the United States, these local discrepancies must be taken into consideration, and scenarios should be revised to reflect contemporary practice. Understanding the concept of AUC as well as its perception gap between different counties will result in the broader implementation of AUC, and lead to the quality improvement of patients’ care in the field of coronary intervention.

    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.

    2016-01-01

    Full Text Available Introduction: Anticoagulation and antiplatelet therapy in the presence of the epidural catheter is still controversial. It is well known that dual antiplatelet therapy is indicated for 12 months after the placement of drug-eluting stents (DES. Removal of an epidural catheter during that period is related to an increased risk of stent occlusion in case of discontinuation of platelet function inhibitors or, on the other hand, increased risk of epidural hematoma associated with neurological deficit if suppressed platelet function is still present. Case Report: Here we present a case of a 63-year-old man who was admitted to Institute for Cardiovascular Diseases Dedinje for elective aortic surgery. Before the induction, an epidural catheter was inserted at the Th10-Th11 epidural space. Uneventful surgery was performed under the combined epidural and general anesthesia. On the 2nd postoperative day, the patient sustained a ST depression myocardial infarction treated with percutaneous coronary intervention with DES placement, while epidural catheter was still in place. Dual antiplatelet therapy with 600mg of clopidogrel, 100 mg of acetilsalicylic acid (ASA and low molecular weight heparin (LMWH were started during the procedure. The next day, clopidogrel (75 mg and ASA (100 mg were continued as well as LMWH. The decision to remove the epidural catheter was made on the 9th postoperative day, after platelet aggregation assays were performed. Six hours after catheter removal the patient again received clopidogrel, ASA and LMWH. There were no signs of epidural hematoma. Conclusion: This case shows that point-of-care testing with platelet aggregation assays may be useful in increasing the margin of safety for epidural catheter removal during dual antiplatelet therapy.

    This study sought to evaluate the effect of age on procedure type, periprocedural management, and in-hospital outcomes of patients undergoing lower-extremity (LE) peripheral vascular intervention (PVI). Surgical therapy of peripheral arterial disease is associated with significant morbidity and mortality in the elderly. There are limited data related to the influence of advanced age on the outcome of patients undergoing percutaneous LE PVI. Clinical presentation, comorbidities, and in-hospital outcomes of patients undergoing LE PVI in a multicenter, multidisciplinary registry were compared between 3 age groups: PVI. The elderly patients were more likely to be female and to have a greater burden of comorbidities. Procedural success was lower in the elderly group (74.2% for age ≥ 80 years vs. 78% for age 70 to PVI can be performed in elderly patients with high procedural and technical success with low rates of periprocedural complications including mortality. These findings may support the notion of using PVI as a preferred revascularization strategy in the treatment of severe peripheral arterial disease in the elderly population.

    The landmark Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) Trial has aided in reducing the area of uncertainty in decision-making between percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery in patients with complex coronary artery disease. As part of the SYNTAX Trial, quantification of the coronary artery disease burden was prospectively undertaken by the Heart Team - consisting of at least an interventional cardiologist and cardiac surgeon - utilising the anatomical SYNTAX Score (www.syntaxscore.com) as a clinical tool in order to agree that equivalent anatomical revascularisation could be achieved. The anatomical SYNTAX Score is now advocated in both European and US revascularisation guidelines to guide decision-making between CABG and PCI as part of the SYNTAX pioneered Heart Team approach. In addition, the SYNTAX Trial has lead to the development and validation of the SYNTAX Score II, in which the anatomical SYNTAX Score was augmented with clinical variables, to allow for more objective and tailored decision making for the individual patient. Prospective validation of the SYNTAX Score II tool is currently ongoing in the SYNTAX II (ClinicalTrials.gov Identifier: NCT02015832) and EXCEL (ClinicalTrials.gov identifier: NCT01205776) trials. The present paper presents lessons learned from SYNTAX, including the development and/or validation of several SYNTAX based clinical tools, and the potential implications for current and future clinical practice.

    The aims of this study were to evaluate the feasibility and technical success of robotically assisted percutaneous coronary intervention (R-PCI) for the treatment of coronary artery disease (CAD) in clinical practice, especially in complex lesions, and to determine the safety and clinical success of R-PCI compared with manual percutaneous coronary intervention (M-PCI). R-PCI is safe and feasible for simple coronary lesions. The utility of R-PCI for complex coronary lesions is unknown. All consecutive PCI procedures performed robotically (study group) or manually (control group) over 18 months were included. R-PCI technical success, defined as the completion of the procedure robotically or with partial manual assistance and without a major adverse cardiovascular event, was determined. Procedures ineligible for R-PCI (i.e., atherectomy, planned 2-stent strategy for bifurcation lesion, chronic total occlusion requiring hybrid approach) were excluded for analysis from the M-PCI group. Clinical success, defined as completion of the PCI procedure without a major adverse cardiovascular event, procedure time, stent use, and fluoroscopy time were compared between groups. A total of 315 patients (mean age 67.7 ± 11.8 years; 78% men) underwent 334 PCI procedures (108 R-PCIs, 157 lesions, 78.3% type B2/C; 226 M-PCIs, 336 lesions, 68.8% type B2/C). Technical success with R-PCI was 91.7% (rate of manual assistance 11.1%, rate of manual conversion 7.4%, rate of major adverse cardiovascular events 0.93%). Clinical success (99.1% with R-PCI vs. 99.1% with M-PCI; p = 1.00), stent use (stents per procedure 1.59 ± 0.79 with R-PCI vs. 1.54 ± 0.75 with M-PCI; p = 0.73), and fluoroscopy time (18.2 ± 10.4 min with R-PCI vs. 19.2 ± 11.4 min with M-PCI; p = 0.39) were similar between the groups, although procedure time was longer in the R-PCI group (44:30 ± 26:04 min:s vs. 36:34 ± 23:03 min:s; p = 0.002). Propensity-matched analysis confirmed that procedure time was longer

    Background Studies conducted decades ago described substantial disagreement and errors in physicians’ angiographic interpretation of coronary stenosis severity. Despite the potential implications of such findings, no large-scale efforts to measure or improve clinical interpretation were subsequently made. Methods & Results We compared clinical interpretation of stenosis severity in coronary lesions with an independent assessment using quantitative coronary angiography (QCA) in 175 randomly selected patients undergoing elective percutaneous coronary intervention (PCI) at 7 U.S. hospitals in 2011. To assess agreement, we calculated mean difference in percent diameter stenosis between clinical interpretation and QCA and a Cohen’s weighted kappa statistic. Of 216 treated lesions, median percent diameter stenosis was 80.0% (Q1 and Q3, 80.0 and 90.0%) with 213 (98.6%) assessed as ≥70%. Mean difference in percent diameter stenosis between clinical interpretation and QCA was +8.2 ± 8.4%, reflecting an average higher percent diameter stenosis by clinical interpretation (P<0.001). A weighted kappa of 0.27 (95% CI, 0.18 to 0.36) was found between the 2 measurements. Of 213 lesions considered ≥70% by clinical interpretation, 56 (26.3%) were <70% by QCA though none was <50%. Differences between the 2 measurements were largest for intermediate lesions by QCA (50 to <70%) with variation existing across sites. Conclusions Physicians tended to assess coronary lesions treated with PCI as more severe than measurements by QCA. Almost all treated lesions were ≥70% by clinical interpretation, while approximately a quarter were <70% by QCA. These findings suggest opportunities to improve clinical interpretation of coronary angiography. PMID:23470859

    Although Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery (SYNTAX) score based on angiographic scoring system was developed in patients with previous coronary artery bypass grafting (CABG), few data exist regarding its prognostic utility in patients undergoing percutaneous coronary intervention (PCI). We examined 272 patients with previous CABG (217 men; mean age, 70.4 ± 9.7 years) undergoing PCI. Severity of the coronary anatomy was evaluated using CABG-SYNTAX score. The primary end point of this study was cardiovascular death. The baseline CABG-SYNTAX score ranged from 2 to 53.5, with an average of 26.0 ± 10.2. In the index procedures, PCI for the native coronary accounted for nearly all patients (88%). During follow-up (median 4.1 years), 40 cardiovascular deaths had occurred. In multivariate analysis, age >75 years (hazard ratio [HR] 2.82, 95% CI 1.45 to 5.52), left ventricular ejection fraction SYNTAX score >25 (HR 2.37, 95% CI 1.19 to 5.05) were independent predictors of cardiovascular death. After creating a composite risk score in consideration of identified predictors, the freedom from cardiovascular death at 5 years was 98%, 86%, and 58% in the low (0 to 1), medium (2), and high (3 to 5) scores, respectively (p SYNTAX and composite risk scores were 0.66 and 0.77, respectively (p <0.05). In conclusion, the combination of angiographic and clinical characteristics is useful for risk stratification in patients with previous CABG undergoing PCI.

    Background Retrospective studies based on clinical data and without spirometric confirmation suggest a poorer prognosis of patients with ischemic heart disease (IHD) and chronic obstructive pulmonary disease (COPD) following percutaneous coronary intervention (PCI). The impact of undiagnosed COPD in these patients is unknown. We aimed to evaluate the prognostic impact of COPD – previously or newly diagnosed – in patients with IHD treated with PCI. Methods Patients with IHD confirmed by PCI were consecutively included. After PCI they underwent forced spirometry and evaluation for cardiovascular risk factors. All-cause mortality, new cardiovascular events, and their combined endpoint were analyzed. Results A total of 133 patients (78%) male, with a mean (SD) age of 63 (10.12) years were included. Of these, 33 (24.8%) met the spirometric criteria for COPD, of whom 81.8% were undiagnosed. IHD patients with COPD were older, had more coronary vessels affected, and a greater history of previous myocardial infarction. Median follow-up was 934 days (interquartile range [25%–75%]: 546–1,160). COPD patients had greater mortality (P=0.008; hazard ratio [HR]: 8.85; 95% confidence interval [CI]: 1.76–44.47) and number of cardiovascular events (P=0.024; HR: 1.87; 95% CI: 1.04–3.33), even those without a previous diagnosis of COPD (P=0.01; HR: 1.78; 95% CI: 1.12–2.83). These differences remained after adjustment for sex, age, number of coronary vessels affected, and previous myocardial infarction (P=0.025; HR: 1.83; 95% CI: 1.08–3.1). Conclusion Prevalence and underdiagnosis of COPD in patients with IHD who undergo PCI are both high. These patients have an independent greater mortality and a higher number of cardiovascular events during follow-up. PMID:26213464

    Background Average life expectancy is rising, resulting in increasing numbers of elderly, frail individuals presenting with coronary artery disease and requiring percutaneous coronary intervention (PCI). PCI can be of value for this population, but little is known about the balance of benefit versus risk, particularly in the frail. Objective To determine the relationship between frailty and clinical outcomes in patients undergoing PCI. Methods Patients undergoing PCI, for either stable angina or acute coronary syndrome, were prospectively assessed for frailty using the Canadian Study of Health and Ageing Clinical Frailty Scale. Demographics, clinical and angiographic data were extracted from the hospital database. Mortality was obtained from the Office of National Statistics. Results Frailty was assessed in 745 patients undergoing PCI. The mean age of patients was 62±12 years and 70% were males. The median frailty score was 3 (IQR 2–4). A frailty score ≥5, indicating significant frailty, was present in 81 (11%) patients. Frail patients required longer hospitalisation after PCI. Frailty was also associated with increased 30-day (HR 4.8, 95% CI 1.4 to 16.3, p=0.013) and 1 year mortality (HR 5.9, 95% CI 2.5 to 13.8, p<0.001). Frailty was a predictor of length of hospital stay and mortality, independent of age, gender and comorbidities. Conclusions A simple assessment of frailty can help predict mortality and the length of hospital stay, and may therefore guide healthcare providers to plan PCI and appropriate resources for frail patients.

    Full Text Available Abstract Background It is uncertain whether black white differences in the use of percutaneous coronary intervention (PCI persist in the era of drug eluting stents. The purpose of this study is to determine if black veterans with acute myocardial infarction (AMI are less likely to receive PCI than their white counterparts. Methods This study included 680 black and 3529 white veterans who were admitted to Veterans Health Administration (VHA medical centers between July 2003 and August 2004. Information for this study was collected as part of the VHA External Peer Review Program for quality monitoring and improvement for a variety of medical conditions and procedures, including AMI. In addition, Department of Veterans Affairs workload files were used to determine PCI utilization after hospital discharge. Standard statistical methods including the Chi-square, 2 sample t-test, and logistic regression with a cluster correction for medical center were used to assess the association between race and the use of PCI ≤ 30 days from admission. Results Black patients were younger, more often had diabetes mellitus, renal disease, or dementia and less often had lipid disorders, previous coronary artery bypass surgery, or chronic obstructive pulmonary disease than their white counterparts. Equal proportions of blacks and whites underwent cardiac catheterization ≤ 30 days after admission, but the former were less likely to undergo PCI (32% vs. 40%, p Conclusion Given the equivalent use of cardiac catheterization, it is possible that less extensive or minimal coronary artery disease in black patients could account for the observed difference.

    Up to 1/3 of percutaneous coronary interventions (PCIs) are complicated by troponin release. Remote ischemic preconditioning (IPC) confers effective cardioprotection; however, a 30-minute remote IPC protocol may be difficult to implement during ad hoc PCI. This study was performed to assess the ability of a brief remote IPC protocol to attenuate cardiac troponin I (cTnI) release after ad hoc PCI. Ninety-four patients undergoing ad hoc PCI for stable coronary artery disease, with undetectable preprocedural cTnI, were recruited and randomized to receive remote IPC (induced by one 5-minute inflation of a blood pressure cuff to 200 mm Hg around the upper arm) or control after the decision for PCI was made. The primary outcome was the difference between cTnI levels 24 hours after PCI and cTnI levels before coronary angiography (ΔcTnI). ΔcTnI in the remote IPC group was significantly lower compared with the control group (0.04 ng/ml [interquartile range 0.01 to 0.14] vs 0.19 ng/ml [interquartile range 0.18 to 0.59], p <0.001). The incidence of PCI-related myocardial infarction (MI) was greater in the control group (42.6% vs 19.1%, p = 0.014). In multivariate analysis, remote IPC was independently associated with ΔcTnI and PCI-related MI. In conclusion, our results suggest that even 1 cycle of remote IPC immediately before ad hoc PCI attenuates periprocedural cTnI release and reduces the incidence of type 4a MI.

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

    To review the effectiveness of manual thrombectomy (MT) in a series of patients with ST-elevation myocardial infarction (STEMI) exclusively presenting with TIMI 0-1 flow undergoing percutaneous coronary intervention (PCI), in accordance to the angiographically estimated area at risk (AAR). Second, to assess major in-hospital clinical events, emphasizing neurological outcomes. The routine utilization of MT in STEMI is not recommended. However, in recent trials, a significant proportion of patients had neither large thrombus burden nor a totally occluded coronary segment, neutralizing the expected benefits of MT. In addition, the efficiency of MT to remove thrombus has rarely been addressed. Finally, MT diminished distal embolization, which has been related to mortality. In 850 consecutive STEMI-patients, MT was utilized in 525 (62%) and it was considered efficient (TIMI 2-3 flow after MT) in 445 (85%). We found a significant interaction between the AAR and the effectiveness of MT to reduce infarct size (P-interaction = 0.014). In patients having AAR ≥ 28% (n = 184), efficient MT conferred lesser infarct size compared to inefficient MT (Ln-transformed peak CK): 7.87 ± 0.86 versus 8.36 ± 0.41 IU/L, P = 0.005, with no impact for AAR <28%. Clinical outcomes including stroke between MT and PCI-only groups were not different. In comparison with the group where MT was inefficient, efficient MT may modestly reduce final infarct size without a significant clinical benefit. In comparison with PCI-only, no difference was found regarding stroke. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Background The Syntax score was recently developed as a comprehensive, angiographic tool grading the complexity of coronary artery disease (CAD). It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention (PCl) has not been validated. The aim of this study was to evaluate its role in predicting long-term incidences of major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing PCl for 3-vessel disease.Methods Two hundred and three consecutive patients with de novo 3-vessel CAD undergoing PCI with sirolimus-eluting stents were studied. Their angiograms were scored according to the Syntax score. The patients were divided into tertiles according to the Syntax score: lowest Syntax score tertile (Syntax score ≤22), intermediate Syntax score tertile (Syntax score of 23 to 32), and the highest Syntax score tertile (Syntax score ≥33). During the 1-year follow-up, the MACCE-free survival curves were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the Syntax score and the incidence of MACCE. Performance of the Syntax score was studied with respect to predicting the rate of MACCE by receiver operator characteristic (ROC) curves with an area under the curve.Results The overall Syntax score ranged from 6 to 66 with mean ± standard deviation of 27.9±12.6 and a median of 26.At 1 year, the Syntax score significantly predicted the risk of MACCE (HR 1.07/U increase, 95% Cl 1.04 to 1.11, P<0.001). The rate of MACCE was significantly increased among patients in the highest Syntax score tertile (17.9%) as compared with those with the lowest Syntax score tertile (1.4%, P <0.001) or intermediate Syntax score tertile (6.2%,P=0.041).

    Background Although thrombolytic therapy with rescue percutaneous coronary intervention (PCI) is a common treatment strategy for ST-segment elevation acute myocardial infarction (STEMI), scant data are available on its efficacy relative to primary PCI, and comparison was therefore the aim of this study.Methods This multicenter, open-label, randomized, parallel trial was conducted in 12 hospitals on patients (age ≤70 years) with STEMI who presented within 12 hours of symptom onset (mean interval >3 hours). Patients were randomized to three groups: primary PCI group (n=101); recombinant staphylokinase (r-Sak) group (n=104); and recombinant tissue-type plasminogen activator (rt-PA) group (n=106). For all patients allocated to the thrombolytic therapy arm, coronary angiography was performed at 90 minutes after drug therapy to confirm infarct-related artery (IRA) patency; rescue PCI was performed in cases with TIMI flow grade ≤2. Bare-metal stent implantation was planned for all patients. Results After randomization it required an average of 113.4 minutes to start thrombolytic therapy (door-to-needle time)and 141.2 minutes to perform first balloon inflation in the IRA (door to balloon time).Rates of IRA patency (TIMI flow grade 2 or 3) and TIMI flow grade 3 were significantly lower in the thrombolysis group at 90 minutes after drug therapy than in the primary PCI group at the end of the procedure (70.5% vs. 98.0%, P <0.0001, and 53.0% vs. 85.9%, P <0.0001, respectively). Rescue PCI with stenting was performed in 117 patients (55.7%) in the thrombolytic therapy arm. Rates of patency and TIMI flow grade 3 were still significantly lower in the rescue PCI than in the primary PCI group (88.9% vs. 97.9%, P=0.0222, and 68.4% vs. 85.0%, P=0.0190, respectively). At 30 days post-therapy, mortality rate was significantly higher in the thrombolysis combined with rescue PCI group than in primary PCI group (7.1% vs. 0, P=0.0034). Rates of death/Ml and bleeding complications were

    Atherosclerotic plaque rupture is the key event in the pathogenesis of acute coronary syndromes and it also occurs during coronary interventions. Atherosclerotic plaque rupture does not always result in complete thrombotic occlusion of the epicardial coronary artery with subsequent impending myocardial infarction, but may in milder forms result in the embolization of atherosclerotic and thrombotic debris into the coronary microcirculation. This review summarizes the present experimental pathophysiology of coronary microembolization in animal models of acute coronary syndromes and highlights the main consequences of coronary microembolization--reduced coronary reserve, microinfarction, inflammation and oxidative modification of contractile proteins, contractile dysfunction and perfusion-contraction mismatch.Furthermore, the review presents the available clinical evidence for coronary microembolization in patients and compares the clinical observations with observations in the experimental model.

    We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event.

    Full Text Available Percutaneous coronary intervention (PCI is increasingly used for unprotected left main coronary artery disease (UPLMS revascularization. Data regarding long-term mortality in this subset of patients remain sparse. We aim to present our outcome data on all comers who had UPLMS PCI. Methods: Retrospective dataset analysis of prospectively collected data evaluating all UPLMS PCI performed in a large tertiary cardiac centre, between September 2003 and December 2012. Long-term mortality data were available over a median duration of 21 months (IQR 10 months to 43 months. Results: In total there were 483 procedures performed. The cohort consisted of 58% with non ST elevation myocardial infarction (NSTEMI, 17% with STEMI and 25% with stable angina (SA. The overall in-hospital and long-term mortality were 7% and 22% respectively. The in-hospital mortality was 23%, 6%, and 1.6% in STEMI, NSTEMI, and SA respectively. Long-term mortality was 31% in STEMI patients, 26% in NSTEMI and 10% in SA. The use of drug eluting stents (DES [adjusted RR 0.40 (95% CI, 0.23-0.69] and Intravascular ultrasound (IVUS [adjusted RR 0.17 (95% CI 0.04-0.72] were independently associated with improved long-term survival. Conclusion: UPLMS PCI is associated with favourable long-term survival. The use of DES and IVUS guided PCI appear to be associated with improved long-term outcome and should be considered in the routine management of this cohort of patients.

    This was a prospective study comparing two groups: personalized and non-personalized treatment with P2Y12 receptor blockers during a 12-month follow-up. We aimed to investigate whether personalized antiplatelet treatment in patients with high on-treatment platelet reactivity (HTPR) improves clinical outcome. Platelet reactivity was assessed by adenosine diphosphate induced aggregation using a multiple electrode aggregometry (MEA) in 798 patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). Patients with HTPR received up to four repeated loading doses of clopidogrel or prasugrel in the personalized treatment group (n=403), whereas no change in the treatment strategy was undertaken in patients with HTPR in the non-personalized treatment group (n=395). There were fewer major adverse cardiac events (MACE) in the personalized treatment group than in the non-personalized treatment group (7.4% compared with 15.3% respectively; Ppersonalized treatment group as compared with the non-personalized treatment group [hazard ratio (HR)=0.49; 95% confidence interval (CI): 0.31-0.77; Ppersonalized antiplatelet treatment over the non-personalized treatment (ischemic and bleedings events: 8.2% versus 18.7% respectively; HR=0.46; 95%CI: 0.29-0.70; Ppersonalized antiplatelet treatment might improve patients' outcome without increasing bleeding complications compared with the non-personalized treatment during a 12-month follow-up.

    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.

    Background. Although the beneficial effects of primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) have been demonstrated in a number of trials, most studies were conducted in Western countries. Experience, logistics and patient characteristics may differ in other parts of the world.Methods. Consecutive patients treated with primary PCI in Cinere Hospital, Jakarta, Indonesia, between January 2008 and October 2008 were compared with those treated in the Isala Clinics, Zwolle, the Netherlands.Results. During the study period, a total of 596 patients were treated by primary PCI, 568 in Zwolle and 28 in Jakarta. Patients in Indonesia were younger (54 vs 63 years), more often had diabetes (36 vs. 12%) and high lipids and were more often smokers (68 vs. 31%). Time delay between symptom onset and admission was longer in Indonesia. Patients from Indonesia more often had signs of heart failure at admission. The time between admission and balloon inflation was longer in Indonesia. At angiography, patients from Indonesia more often had multivessel disease. There was no difference in the percentage of restoration of TIMI 3 flow by primary PCI between the two hospitals.Conclusion. Patients with STEMI in Indonesia have a higher risk profile compared with those in the Netherlands, according to prevalence of coronary risk factors, signs of heart failure, multivessel disease and patient delay. Time delay between admission and balloon inflation was much longer in Indonesia, because of both logistic and financial reasons. (Neth Heart J 2009;17:418-21.).

    We evaluated the impact of clopidogrel 150 mg/d in patients with chronic kidney disease (CKD) having clopidogrel resistance (CR) after percutaneous coronary intervention (PCI); 1076 consecutive patients with coronary artery disease (CAD) having CKD were enrolled. Maximal platelet aggregation (MPA) was assessed before, 24 hours, and 30 days after a 300-mg loading dose of clopidogrel prior to PCI. After PCI, 370 patients with CR were randomized to receive clopidogrel 75 mg/d (n = 184) or 150 mg/d (n = 186) for 30 days. Stent thrombosis (ST), major adverse cardiac events (MACEs), and bleeding were analyzed after 1 month. Patients in the 150 mg group had significant lower rates of ST and MACE. There was no significant difference in major or minor bleeding. Patients in the 150 mg group had lower MPA and greater inhibition of platelet aggregation. One-month administration of 150 mg/d of clopidogrel decreases the rate of ST and MACE without increasing bleeding in patients with CKD having CR after PCI.

    Slender chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using 5 Fr radial Ikari catheter is possible in simple CTO cases. We report a case where we initially thought the LAD CTO was short and easy, but we found that the CTO had a considerable amount of calcium and also some tortuosity, making simple wire crossing impossible. We used a Stingray balloon to perform re-entry by tracking the balloon over an Ultimate Bros 3 gram wire using an extension wire. We successfully punctured into true lumen and completed stenting through a slender 5 Fr system. This case demonstrates the beauty of combining the advances in CTO PCI from the East and the West together and also demonstrates the possibility of using the Stingray system in a 5 Fr guiding catheter.

    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.

    2015-02-01

    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.

    savings associated with coumarin treatment were estimated at € 235 per patient after one year. Conclusions Coumarin pretreatment reduces early and late events in patients undergoing percutaneous coronary intervention at the expense of a small increase in nonfatal bleeding complications. Furthermore, an optimal level of anticoagulation is associated with a significantly better outcome as compared with a suboptimal level of anticoagulation. In addition, coumarin treatment reduces costs. ImagesFigure 1 PMID:25696099

    Patients with complex coronary lesions undergoing percutaneous coronary intervention (PCI) have more major adverse cardiac events (MACE) than do those with simpler cases. Therefore, intensive antiplatelet therapy might be needed in these patients. A total of 127 patients with complex lesions undergoing PCI in the Second Hospital of Tianjin Medical University from October 2012 to April 2014 were randomized to receive either dual (aspirin plus clopidogrel, DAPT, n = 66), or triple antiplatelet therapy (aspirin plus clopidogrel plus cilostazol; TAPT, n = 61). Patients in the TAPT group received low-dose cilostazol (100 mg loading, followed with 50 mg twice per day) for 3-6 months. The primary endpoint was composite MACE. The complex coronary target lesions were defined as at least one of the following: left main disease; severe 3-vessel disease; chronic total occlusion lesions; true bifurcation lesion; ostial lesions; severe calcified lesions; and highly thrombotic lesions. The two groups had similar baseline clinical and angiographic characteristics. One-year clinical outcomes showed that the TAPT group had significantly lower incidences of myocardial infarction (1.6% vs 13.6%, P = 0.018) and MACE (1.6% vs 16.7%, P = 0.004) than DAPT group. The DAPT group had two cases of stent thrombosis, while the TAPT group did not. Furthermore, adjunctive low-dose cilostazol didn't significantly increase the incidence of bleeding events (26.2% vs 19.7%, P = 0.381) regardless of major (4.9% vs 4.5%, P = 0.921) or minor (21.3% vs 15.2%, P = 0.368) bleeding events. In conclusion, low-dose adjunctive cilostazol seems superior to dual antiplatelet therapy in reducing recurrent ischemic events in patients with complex coronary lesions and the two test groups have a similar incidence of bleeding events. © 2015 Wiley Publishing Asia Pty Ltd.

    We use microsimulation to forecast changes in coronary heart disease (CHD) among adults 45 or above over a 20-year time horizon in Los Angeles County (N = 3.4 million), a county with 12 635 CHD deaths in 2010. We simulate individuals' life course and calibrate CHD trends to observed trends in the past. Using the Health Forecasting Community Health Simulation Model, we simulate CHD prevalence and CHD mortality in 2 CHD prevention scenarios: (1) "comprehensive hypertension intervention" and (2) "gradual reduction of the average adult body mass index back to the year 2000 level." We use microsimulation methodology so that nonprofit hospitals can easily use our model to forecast intervention results in their specific hospital catchment area. Our baseline model (without intervention) forecasts an increase in CHD prevalence that will reach 13.01% among those 45+ in Los Angeles County in 2030. Under scenario 1, the increase in CHD prevalence is slower (12.47% in 2030), and the prevalence in scenario 2 reaches 12.83% in 2030. The baseline scenario projects a number of 21 300 CHD deaths in 2030, whereas there will be 20 070 CHD deaths under scenario 1 and 20 970 CHD deaths under scenario 2. At the population level, the CHD mortality outcome, as compared with the metric of CHD prevalence, might be more sensitive to preventive lifestyle interventions. Both CHD prevalence and CHD mortality might be more sensitive to the hypertension intervention than to the obesity reduction in the time horizon of 20 years.

    Introduction Although dual antiplatelet therapy (DAPT) is routinely given to patients after percutaneous coronary intervention (PCI) with stenting, the optimal duration is unknown. Recent evidence indicates there may be benefits in extending the duration beyond 12 months but such decisions may increase the risk of bleeding. Our objective is to provide a comprehensive overview of the literature for clinicians and policymakers via an umbrella review assessing the optimal duration of DAPT. Methods and analysis We will perform a comprehensive search of the published and grey literature for systematic reviews involving randomised controlled trials (RCTs) assessing the optimal duration of DAPT following PCI with stenting. The intervention of interest is extended DAPT (beyond 12 months) compared with short-term DAPT (6–12 months). Studies will be selected for inclusion by two reviewers, and the quality will be assessed. The primary outcomes of interest are all-cause mortality and cardiovascular mortality. Secondary outcomes will be bleeding (major, minor and gastrointestinal), urgent target vessel revascularisation, major adverse cardiovascular events, myocardial infarction, stroke and stent thrombosis. Outcomes will be assessed while on DAPT and after withdrawal of DAPT. Data will be summarised with respect to the number of included RCTs, number of participants, effect estimates and heterogeneity. Data will be reported separately based on patient demographics, procedural parameters (eg, stent types, lesion complexity and concurrent disease) and clinical presentation (eg, acute coronary syndromes, infarct type). Ethics and dissemination Our umbrella review aims to provide a comprehensive overview of the benefits and harms associated with extending DAPT beyond 12 months following PCI with stenting. The results of this review will inform clinical and policy decisions regarding the optimal treatment duration and reimbursement of DAPT following PCI with stenting

    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 PMI score ≥ 10) (P PMI. The PMI score could help identify patients at high risk of PMI after PCI. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Objectives: The aim of current study is to evaluate relation between body mass index (BMI and in-hospital outcome in patients undergoing percutaneous coronary intervention (PCI.Background: Relation between body mass indexes (BMI with percutaneous coronary intervention (PCI has shown in different studies. Recent studies suggested a paradox relation between different BMI values and outcome in certain patients.Methods: In this prospective study, 1134 patients (81.7% male, 18.3% female with mean age of 58.18±11.16 years whom undergone PCI between January 2011 and December 2011 were chosen and their BMI and disease outcome was studied. Classification of BMI was: healthy weight (18.5 to 24.9 kg/m2, overweight (25 to 29.9 kg/m2, moderate obesity (30 to 34.9 kg/m2 and severe obesity (over 35 kg/m2. Baseline patient characteristics and in-hospital outcome were compared among BMI categories.Results: Major adverse cardiac events (MACE were significantly higher in patients with overweight and moderate obesity than two other groups. There was no difference in mortality, reinfarction, revascularisation, stroke and bleeding events among the 4 groups. Being overweight is an independent factor associated to in-hospital MACE (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.17 to 0.73, p=0.01 and mortality rate (OR 0.20, 95%CI 0.04 to 0.85, p=0.03.Conclusion: BMI overall is not correlated to in-hospital MACE and mortality; however, overweight patients are at reduced risk for MACE and mortality.

    In complex coronary artery disease, it is sometimes difficult to determine which lesions are associated with reversible ischemia and should be stented. Fractional flow reserve (FFR) is an established objective methodology to indicate which lesions produce ischemia. Despite this, the selection of lesions to be stented is often based on the subjectively interpreted angiogram alone. The aim of this study in patients admitted for elective percutaneous intervention (PCI) was to evaluate the change in strategy if the decision to intervene was based on FFR measurement rather than on angiographic assessment. Two hundred fifty consecutive patients (471 arteries) scheduled for PCI were included in this study. All stenoses >or=50% by visual estimation and initially selected to be stented by 3 independent reviewers were assessed by FFR measurements. If FFR was or=0.75, no interventional treatment was given. Optimal pressure measurements were obtained in 452 lesions (96%). Diameter stenosis was 62 +/- 12%, and FFR was 0.67 +/- 0.17 for the entire group. In 68% of the stenoses, initial strategy as assessed from the angiogram was followed, and in 32%, there was a change in the planned approach based on FFR. In 48% of the patients, there was >or=1 lesion in which the treatment decision was changed after physiologic measurements. In conclusion, in this prospective, nonselective, but complete study representing the real world of PCI, 32% of the coronary stenoses and 48% of patients would have received a different treatment if the decision had been based on angiography only, stressing the utility of physiologic assessment in refining decision making during PCI.

    Background Radial artery spasm (RAS) is the most common complication in transradial coronary angiography and intervention. In this study, we designed to investigate the incidence of RAS during transradial procedures in Chinese, find out the independent predictors through multiple regression, and analyze the clinical effect of RAS during follow-up. Methods Patients arranged to receive transradial coronary angiography and intervention were consecutively enrolled. The incidence of RAS was recorded. Univariate analysis was performed to find out the influence factors of RAS, and logistic regression analysis was performed to find out the independent predictors of RAS. The patients were asked to return 1 month later for the assessment of the radial access.Results The incidence of RAS was 7.8% (112/1427) in all the patients received transradial procedure. Univariate analysis indicates that young (P=0.038), female (P=0.026), small diameter of radial artery (P 3) (P=0.048), rapid baseline heart rate (P=0.032) and long operation time (P=0.021) were associated with RAS. Logistic regression showed that female (OR=1.745, 95% CI: 1.148-3.846, P=0.024), small radial artery diameter (OR=4.028, 95%CI: 1.264-12.196, P=0.008), diabetes (OR= 2.148, 95%CI: 1.579-7.458, P=0.019) and unsuccessful access at first attempt (OR=1.468, 95%CI: 1.212-2.591, P=0.032) were independent predictors of RAS. Follow-up at (28±7) days after the procedure showed that, compared with non-spasm patients, the RAS patients had higher portion of pain (11.8% vs. 6.2%, P=0.043). The occurrences of hematoma (7.3% vs. 5.6%, P=0.518) and radial artery occlusion (3.6% vs. 2.6%, P=0.534) were similar. Conclusions The incidence of RAS during transradial coronary procedure was 7.8%. Logistic regression analysis showed that female, small radial artery diameter, diabetes and unsuccessful access at first attempt were the independent predictors of RAS.

    Background Bivalirudin was widely used as an anticoagulant during coronary interventional procedure in western countries.However,it was not available in China before this clinical trial was designed.This randomized,single-blind and multicenter clinical trial aimed to evaluate the efficacy and the safety of domestic bivalirudin during percutaneous coronary intervention (PCI).Methods A randomized,single-blind,multicenter trial was designed.Elective PCI candidates in five centers were randomized into a bivalirudin group and a heparin group,which were treated with domestic bivalirudin and non-fractional heparin during the PCI procedure.The efficacy was evaluated by comparing the activated coagulation time (ACT),the procedural success rate (residual stenosis <20% in target lesions without any coronary artery related adverse events within 24 hours after PCI),and the survival rate without major adverse cardiac events at 30 days after PCI between the two groups.Safety was evaluated by the major/minor bleeding rate.Results A total of 218 elective PCI patients were randomized into a bivalirudin group (n=110) and heparin group (n=108).Except for two patients needing additional dosing in the heparin group,the ACT values of all other patients in both groups were longer than 225 seconds at 5 minutes after the first intravenous bolus.Procedural success rates were respectively 100.0% and 98.2% in the bivalirudin group and heparin group (P>0.05).Survival rates without major adverse cardiac events at 30 days after PCI were 100.0% in the bivalirudin group and 98.2% in the heparin group (P>0.05).Mild bleeding rates were 0.9% and 6.9% (P<0.05) at 24 hours,and 1.9% and 8.8% (P<0.05) at 30 days after PCI in the bivalirudin group and heparin group respectively.There was one severe gastrointestinal bleeding case in the heparin group.Conclusions Domestic bivalirudin is an effective and safe anticoagulant during elective PCI procedures.The efficacy is not inferior

    This study sought to evaluate in-hospital outcomes and 3-year mortality of patients presenting with unprotected left main stem occlusion (ULMSO) treated with primary percutaneous coronary intervention (PPCI). Limited data exists about management and outcome following presentation with ULMSO. From January 1, 2007 to December 21, 2012, 446,257 PCI cases were recorded in the British Cardiovascular Intervention Society database of all PCI cases in England and Wales. Of those, 568 were patients having emergency PCI for ST-segment elevation infarction (0.6% of all PPCI) who presented with ULMSO (TIMI [Thrombolysis In Myocardial Infarction] flow grade 0/1 and stenosis >75%), and they were compared with 1,045 emergency patients treated with nonocclusive LMS disease. Follow-up was obtained through linkage with the Office of National Statistics. Presentation with ULMSO, compared with nonocclusive LMS disease, was associated with a doubling in the likelihood of periprocedural shock (57.9% vs. 27.9%; p < 0.001) and/or intra-aortic balloon pump support (52.5% vs. 27.2%; p < 0.001). In-hospital (43.3% vs. 20.6%; p < 0.001), 1-year (52.8% vs. 32.4%; p < 0.001), and 3-year mortality (73.9% vs 52.3%, p < 0.001) rates were higher in patients with ULMSO, compared with patients presenting with a patent LMS, and were significantly influenced by the presence of cardiogenic shock. ULMSO and cardiogenic shock were independent predictors of 30-day (hazard ratio [HR]: 1.61 [95% confidence interval (CI): 1.07 to 2.41], p = 0.02, and HR: 5.43 [95% CI: 3.23 to 9.12], p<0.001, respectively) and 3-year all-cause mortality (HR: 1.52 [95% CI: 1.06 to 2.17], p = 0.02, and HR: 2.98 [95% CI: 1.99 to 4.49], p < 0.001, respectively). In patients undergoing PPCI for ULMSO, acute outcomes are poor and additional therapies are required to improve outcome. However, long-term outcomes for survivors of ULMSO are encouraging.

    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 OBJECTIVE: We conducted a comparative analysis of the in-hospital outcomes of patients who underwent primary percutaneous transluminal angioplasty (PTCA or stent implantation because of an acute myocardial infarction (AMI related to an acute vein graft occlusion. METHODS: Since 1991 the Brazilian Society of Hemodynamic and Interventional Cardiology has maintained a large database (CENIC. From these, we selected all consecutive patients, who underwent primary PTCA or stenting in the first 24 hours of AMI, with the target vessel being an occluded vein graft. Immediate results and major coronary events occurring up until hospital discharge were analyzed. RESULTS: During this period, 5,932 patients underwent primary PTCA or stenting; 158 (3% of the procedures were performed because of an acute vein graft occlusion. Stenting was performed in 74 (47% patients. Patients treated with stents had a higher success rate and lower mean residual stenosis compared with those who underwent primary balloon PTCA. The incidence of reinfarction and death were similar for stenting and balloon PTCA. CONCLUSION: Primary percutaneous treatment of AMI related to acute vein graft occlusion is still an uncommon practice. Primary stenting improved luminal diameter and offered higher rates of success; however, this strategy did not reduce the in-hospital reinfarction and death rate, compared with that occurring with PTCA treatment.

    Our data shows the regional coronary artery calcium scores (lesion CAC) on multidetector computed tomography (MDCT) and the cross-section imaging on MDCT angiography (CTA) in the target lesion of the patients with stable angina pectoris who were scheduled for percutaneous coronary intervention (PCI). CAC and CTA data were measured using a 128-slice scanner (Somatom Definition AS+; Siemens Medical Solutions, Forchheim, Germany) before PCI. CAC was measured in a non-contrast-enhanced scan and was quantified using the Calcium Score module of SYNAPSE VINCENT software (Fujifilm Co. Tokyo, Japan) and expressed in Agatston units. CTA were then continued with a contrast-enhanced ECG gating to measure the severity of the calcified plaque condition. We present that both CAC and CTA data are used as a benchmark to consider the addition of rotational atherectomy during PCI to severely calcified plaque lesions.

    The optimal preoperative therapeutic strategy for patients with coronary artery disease (CAD) is an important concern in the era of drug-eluting stents and antiplatelet therapy. However, there are few studies about the impact of prior percutaneous coronary intervention (PCI) on perioperative major adverse cardiac events (MACEs) and bleeding events associated with oral antiplatelet therapy. The aim of this study was to examine the risks and benefits of performing PCI before non-cardiac surgery (NCS) in patients with CAD. We investigated 130 patients who had angiographically significant and stable CAD and underwent NCS after index coronary angiography. We divided the patients into two groups: patients undergoing PCI with coronary stenting (PCI group), and those not undergoing PCI before NCS (no-PCI group), and compared the MACEs and bleeding events within 30 days from NCS between the groups. There were 53 and 77 patients in the PCI and no-PCI groups, respectively. MACEs were observed in 2 patients (3.8%) in the PCI group and 3 patients (3.9%) in the no-PCI group (p=0.97), whereas bleeding events were observed in 10 (18.9%) and 8 patients (10.4%) in the PCI and no-PCI groups, respectively (p=0.17). There were no significant differences between the two groups in terms of MACEs and bleeding events. The rate of MACEs following NCS was not significantly different between the PCI and no-PCI groups, while the rate of bleeding events was higher in the PCI group without reaching statistical significance. This study suggests that patients with stable CAD may be able to safely undergo NCS without revascularization even in the presence of significant coronary artery stenosis.

    Purpose: Three-dimensional (3-D) reconstruction of the coronary arteries during a cardiac catheter-based intervention can be performed from a C-arm based rotational x-ray angiography sequence. It can support the diagnosis of coronary artery disease, treatment planning, and intervention guidance. 3-D reconstruction also enables quantitative vessel analysis, including vessel dynamics from a time-series of reconstructions. Methods: The strong angular undersampling and motion effects present in gated cardiac reconstruction necessitate the development of special reconstruction methods. This contribution presents a fully automatic method for creating high-quality coronary artery reconstructions. It employs a sparseness-prior based iterative reconstruction technique in combination with projection-based motion compensation. Results: The method is tested on a dynamic software phantom, assessing reconstruction accuracy with respect to vessel radii and attenuation coefficients. Reconstructions from clinical cases are presented, displaying high contrast, sharpness, and level of detail. Conclusions: The presented method enables high-quality 3-D coronary artery imaging on an interventional C-arm system.

    Patients treated with clopidogrel who have ≥1 loss of function alleles for CYP2C19 have an increased risk for adverse cardiovascular events. In 2010, the US Food and Drug Administration issued a boxed warning cautioning against the use of clopidogrel in such patients. We sought to assess the impact of CYP2C19 genetic testing on prescribing patterns for antiplatelet therapy among patients with acute coronary syndrome or percutaneous coronary intervention. Patients with recent acute coronary syndrome or percutaneous coronary intervention prescribed clopidogrel were offered CYP2C19 testing. Genotype and phenotype results were provided to patients and their physicians, but no specific treatment recommendations were suggested. Patients were categorized based on their genotype (carriers versus noncarriers) and phenotype (extensive, intermediate, and poor metabolizers). The primary outcome was intensification in antiplatelet therapy defined as either dose escalation of clopidogrel or replacement of clopidogrel with prasugrel. Between July 2010 and April 2012, 6032 patients were identified, and 499 (8.3%) underwent CYP2C19 genotyping, of whom 146 (30%) were found to have ≥1 reduced function allele, including 15 (3%) with 2 reduced function alleles. Although reduced function allele carriers were significantly more likely than noncarriers to have an intensification of their antiplatelet therapy, only 20% of poor metabolizers of clopidogrel had their antiplatelet therapy intensified. Providers were significantly more likely to intensify antiplatelet therapy in CYP2C19 allele carriers, but only 20% of poor metabolizers of clopidogrel had an escalation in the dose of clopidogrel or were switched to prasugrel. These prescribing patterns likely reflect the unclear impact and evolving evidence for clopidogrel pharmacogenomics.

    Internet interventions often rely on convenience sampling, yet convenience samples may differ in important ways from systematic recruitment approaches. The purpose of this study was to evaluate potential demographic, medical, and psychosocial differences between Internet-recruited and registry-recruited cancer survivors in an Internet-based intervention. Participants were recruited from a cancer registry (n = 80) and via broad Internet outreach efforts (n = 160). Participants completed a set of self-report questionnaires, and both samples were compared to a population-based sample of cancer survivors (n = 5,150). The Internet sample was younger, better educated, more likely to be female, had longer time since diagnosis, and had more advanced stage of disease (p's sample was over-represented by men and those with prostate or other cancer types (p's sample also exhibited lower quality of life and social support and greater mood disturbance (p's convenience and systematic samples differ has important implications for external validity and potential for dissemination of Internet-based interventions.

    Full Text Available Objectives: The aim of this study was to evaluate the clinical outcomes, one year after primary percutaneous coronary intervention(PCI. 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. Of subjects with multivessel disease, 7% died after one-year (P= 0.161, but there was no reported mortality in those with single vessel disease.

    A 54-year-old black African woman, 22 years human immunodeficiency virus (HIV)-positive, presented with an acute coronary syndrome. She was taking two nucleoside reverse transcriptase inhibitors and two protease inhibitors. Viral load and CD4 count were stable. Angiography revealed a right coronary artery lesion, which was treated with everolimus eluting stent. She also underwent balloon angioplasty to the first diagonal. She re-presented on three different occasions and technically successful coronary intervention was performed. The patient has reported satisfactory compliance with dual anti platelet therapy throughout. She was successfully treated with surgical revascularisation. The patient did not experience any clinical recurrence on follow up. This case demonstrates exceptionally aggressive multifocal and recurrent instent restenosis in a patient treated for HIV infection, raising the possibility of an association with HIV infection or potentially components of retro viral therapy.

    Patients with high-risk coronary lesions may be denied coronary artery bypass grafting due to excessive comorbidities. Percutaneous coronary intervention (PCI) may be a feasible revascularization strategy in high-risk patients who present with ST-elevation myocardial infarction and cardiogenic shock. Historically, the use if intra-aortic balloon pump (IABP) has been used in high-risk PCI and cardiogenic shock. However, recent data has shown that elective IABP insertion did not reduce the incidence of major cardiovascular events following PCI. The use of a left ventricular assist device is a reasonable and safe alternative compared with IABP counterpulsation, giving greater cardiac output and hemodynamic support in patients undergoing high-risk PCI and in those with severe cardiogenic shock. This review outlines a case of severe cardiogenic shock and hemodynamic instability where high-risk PCI is a reasonable option.

    The aim of our study was to investigate the influence of prior cytomegalovirus (CMV) or Chlamydia pneumoniae (CP) infection on prognosis after percutaneous coronary intervention (PCI). Using the enzyme-linked immunosorbent assay technique preprocedural anti-CMV immunoglobulin G and anti-CP immunoglobulin A (CP IgA), immunoglobulin M, and immunoglobulin G antibodies were measured. Repeat anginal complaints and major adverse clinical events (MACE), including PCI, coronary artery bypass grafting, myocardial infarction, and death, were recorded at 8-month follow-up. Six hundred consecutive patients were included after successful PCI. Sixty-four percent of the patients were stented. The mean age was 61.6 years, and 68.9% were male. The rate of seropositivity for CP IgA in patients with MACE as compared with patients without MACE was 50.9% versus 35.4% (P =.0276). In patients with repeat anginal complaints, CP IgA seropositivity was 41.6% versus 34.6% in patients without repeat angina (P =.1057). The negative effect of CP on prognosis was confirmed after calculating the odds ratios for MACE (1.9, 95% CI 1.1-3.3). The rates of seropositivity for anti-CMV immunoglobulin G were not significantly different between both groups, although we found an association between infectious burden and repeat angina pectoris (odds ratio 1.8, 95% CI 1.1-3.0). We conclude that preprocedural seropositivity of CP IgA is a risk factor for MACE and angina pectoris after PCI. Although no such relation was found for CMV alone, the cumulative infectious burden was also related to these clinical manifestations of restenosis.

This study was designed to determine the effect of primary percutaneous coronary intervention (PCI in patients with CAVB complicating acute inferior STEMI, at a single center.Methods: We enrolled 138 consecutive patients diagnosed with STEMI involving the inferior wall; of these, 27 patients had CAVB. All patients received primary PCI. The clinical characteristics, procedural data, and clinical outcomes were compared in patients with versus without CAVB. Results: Baseline clinical characteristics were similar between patients with and without CAVB. Patients with CAVB were more likely to present with cardiogenic shock, and CAVB was caused primarily by right coronary artery occlusion. Door-to-balloon time was similar between those two groups. After primary PCI,
