    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.

    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.

    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

    The goal of this study was to explore the polymorphisms of CYP2C19 (CYP2C19*2, CYP2C19*3) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) on clopidogrel therapy in Zhengzhou city for guidance on clinical medication and reduction in the incidence of thromboembolic events. Two hundred and thirty-four ACS patients undergoing PCI were included in the study, including 171 males (average age = 64.13 ± 12 years) and 63 females (average age = 67.86 ± 10.20 years). Pyrosequencing analysis detected CYP2C19*2/*3 genotypes, which were divided into wild-type homozygous C/C, mutant heterozygous C/T, and mutant homozygous T/T. This study further explored the relationship between CYP2C19 polymorphisms and clopidogrel resistance in ACS patients. Gene frequencies of C/C, C/T, and T/T for CYP2C19*2 were 39.74, 50, and 10.26%, respectively, while the frequencies of C/C, C/T, and T/T for CYP2C19*3 were 94.02, 5.55, and 0.43%, respectively. According to platelet aggregation analysis, 203 cases normally responded to clopidogrel (86.8%) and 31 cases were clopidogrel resistant (13.2%). There was a correlation between gender and genotype distribution but none between age and genotype. In addition, patients with clopidogrel resistance were treated with ticagrelor antiplatelet therapy instead of clopidogrel, and only 1 case in all patients suffered thrombotic events during a 3-12 month follow-up. In conclusion, CYP2C19*2/*3 polymorphisms may be associated with clopidogrel resistance. Wild-type homozygote and single mutant heterozygote of CYP2C19*2/*3 can be given a normal dose of clopidogrel, while carriers with single mutant homozygote or double mutant heterozygote require ticagrelor antiplatelet therapy as an alternative.

    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...

    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.

    Background For patients with moderate to high-risk acute coronary syndromes(ACS)who undergo early,invasive treatment strategies,current guidelines recommend the usage of glycoprotein(GP)lib/Illa inhibitors as an upstream treatment for a coronary care unit or as an downstream provisional treatment for selected patients who are undergoing percutaneous coronary intervention(PCI).The relative advantage of either strategy is unknown.The purpose of this study was to evaluate the effects of upstream tirofiban versus the effects of downstream tirofiban on myocardial damage and 180-day major adverse cardiovascular events(MACE)after PCI in high-risk non-ST-segment elevation ACS (NSTE-ACS)undergoing PCI.Methods From July 2006 to July 2007,160 high-risk NSTE-ACS undergoing PCI were randomized to receive upstream (within 4-6 hours before coronary angiography)tirofiban or downstream(the guidewire crossing the lesion)tirofiban,to evaluate the extent of myocardial damage after PCI by quantitatively and qualitatively analyzing the value of cardiac troponin I(cTnl)as well as MB isoenzyme of creatine kinase(CK-MB)before and after PCI.The incidences of 24-hour,3-day,7-day,30-day and 180-day MACE after PCI were followed up and the rates of bleeding complications and thrombocytopenia during tirofiban administration were recorded.Results The peak release and cumulative release of cTnl levels within 48 hours after PCI were significantly lower with upstream tirefiban than downstream tirofiban(0.45 vs 0.63 and 0.32 vs 0.43,respectively;P<0.05).Post-procedural cTnl elevation within 48 hours was significantly less frequent among patients who received the upstream tirofiban than those who received the downstream tirefiban(66.3%vs 87.5%,P<0.05).The peak and cumulative release of CK-MB levels as well as post-procedural CK-MB elevation within 48 hours after PCI were not significantly different between the two groups (16 vs 14,5 vs 3 and 26.3%vs 36.3%,respectively;P>0.05).The incidences of

    Contrast-induced nephropathy (CIN) is one of the major causes of hospital-acquired acute renal failure. The pathophysiological mechanism of CIN remains unknown. There has been little evidence regarding the effects of Traditional Chinese Medicine (TCM) on CIN. Cordyceps sinensis (CS), a traditional Chinese herb, has been widely used clinically for the prevention of the progression of renal failure. We performed a prospective, randomized controlled trial to investigate the role of CS in the prevention of CIN in patients with acute coronary syndrome (ACS) undergoing elective percutaneous coronary intervention (PCI). The 150 ACS patients were randomly assigned to three groups, basic treatment group (n=51), standard CS therapy group (n=49, corbrin capsule 2 g, 3 times/d were used 3 days before and after angiography), and intensive CS therapy group (n=50, corbrin capsule 3 g, 3 times/d were used 3 days before and after angiography). Renal function was assessed at the time of hospital admission and on days 1, 2, and 3 after PCI. CIN occurred in 13 of 150 patients (8.67%). The incidence of CIN was lower in the CS treatment groups than in the basic treatment group (P<0.05), and a significant decrease in the incidence of CIN in the intensive CS therapy group was shown (P<0.01). In conclusion, prophylactic treatment with CS during the peri-procedural stage in ACS patients undergoing elective PCI has a preventive role against CIN, and intensive CS therapy could be more effective.

    Full Text Available This study seeks to investigate potential cardioprotection of Danlou Tablets in patients undergoing PCI with non-ST elevation acute coronary syndrome (NSTE-ACS. 219 patients with NSTE-ACS were randomised to Danlou Tablet pretreatment (n=109 or placebo (n=110. No patients received statins prior to PCI and all patients were given atorvastatin (10 mg/day after procedure. The main endpoint was the composite incidence of major adverse cardiac events (MACEs within 30 days after PCI. The proportion of patients with elevated levels of cTn I>5 × 99% of upper reference limit was significantly lower in the Danlou Tablet group at 8 h (22.0% versus 34.5%, p=0.04 and 24 h (23.9% versus 38.2%, p=0.02 after PCI. The 30-day MACEs occurred in 22.0% of the Danlou Tablet group and 33.6% in the placebo group (p=0.06. The incidence of MACE at 90-day follow-up was significantly decreased in the Danlou Tablet group compared to the placebo group (23.9% versus 37.3%, p=0.03. The difference between the groups at 90 days was the incidence of nonfatal myocardial infarction (22% versus 34.5%, p=0.04. These findings might support that treatment with Danlou Tablet could reduce the incidence of periprocedural myocardial infarction in patients with ACS undergoing PCI.

    Young women undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) experience greater adverse events than men, potentially due to under-treatment. We sought to compare the 1-year outcomes by sex in patients ≤55 years of age from a contemporary PCI cohort. PROMETHEUS was a retrospective multicenter observational US study comparing outcomes in clopidogrel and prasugrel treated patients following ACS PCI. MACE was defined as a composite of death, myocardial infarction, stroke or unplanned revascularization. Clinically significant bleeding was defined as bleeding requiring transfusion or hospitalization. Hazard ratios were generated using multivariable Cox proportional hazards regression. The study cohort included 4,851 patients of which 1,162 (24.0%) were women and 3,689 (76.0%) were men. In this cohort, the prevalence of diabetes (41.0 vs. 27.9%) and chronic kidney disease (12.7 vs. 7.2%) was higher among women compared with men. Irrespective of sex, prasugrel was used in less than one-third of patients (31.8% in men vs. 28.1% in women, P = 0.01). Unadjusted, 1-year MACE (21.1% vs. 16.2%, P < 0.001) and bleeding (3.6% vs. 2.2%, P = 0.01) was significantly higher in women compared with men, but these results were no longer significant after adjustment for risk (HR 1.13, 95% CI 0.94-1.36 for MACE and HR 1.31, 95% CI 0.85-2.04 for bleeding). Women ≤ 55 years of age undergoing ACS PCI have significantly greater comorbidities than young men. Despite a higher risk clinical phenotype in women, prasugrel use was significantly lower in women than men. Female sex was associated with a significantly higher risk of 1-year MACE and bleeding than male sex, findings that are attributable to baseline differences. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    We investigated the use of a 3-hr treatment with hemodiafiltration, initiated soon after emergency or urgent coronary angiography in acute coronary syndrome (ACS) patients with associated severe renal and cardiac dysfunction. Patients with ACS and severe combined renal and cardiac dysfunction have a particularly high mortality risk. In them, the ideal strategy to both optimize treatment of coronary disease and minimize renal injury risk is currently unknown. This was an interventional study. ACS patients (STEMI and NSTEMI) with associated severe renal (eGFR ≤30 ml/min/1.73 m(2) ) and cardiac (LVEF ≤40%) dysfunction, admitted at La Spezia Hospital emergency coronary procedure. Controls were patients matched for age, gender, Mehran's risk score, and kind of ACS, admitted at the Centro Cardiologico Monzino Milan. In-hospital and 1-year outcomes were evaluated. Sixty patients (30% STEMI), 30 hemodiafiltration-treated patients and 30 controls, with similar baseline characteristics, were included. In-hospital and cumulative 1-year mortality rates were significantly lower in hemodiafiltration-treated patients than in controls (3% vs. 23%; P = 0.05, and 10% vs. 53%; P emergency coronary angiography seems to be associated with a relevant improvement in survival. © 2014 Wiley Periodicals, Inc.

    Acute kidney injury (AKI) is a common complication after coronary angiography. Early biomarkers of this disease are needed since increase in serum creatinine levels is a late marker. To assess the usefulness of urinary kidney injury molecule-1 (uKIM-1), neutrophil gelatinase-associated lipocalin (uNGAL) and liver-type fatty acid-binding protein (uL-FABP) for early detection of AKI in these patients, comparing their performance with another group of cardiac surgery patients. Biomarkers were measured in 193 patients, 12 h after intervention. In the ROC analysis, AUC for KIM-1, NGAL and L-FABP was 0.713, 0.958 and 0.642, respectively, in the coronary angiography group, and 0.716, 0.916 and 0.743 in the cardiac surgery group. Urinary KIM-1 12 h after intervention is predictive of AKI in adult patients undergoing coronary angiography, but NGAL shows higher sensitivity and specificity. L-FABP provides inferior discrimination for AKI than KIM-1 or NGAL in contrast to its performance after cardiac surgery. This is the first study showing the predictive capacity of KIM-1 for AKI after coronary angiography. Further studies are still needed to answer relevant questions about the clinical utility of biomarkers for AKI in different clinical settings.

    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.

    The aim of this study was to examine the incidence, correlates, and consequences of intra-procedural stent thrombosis (IPST) in patients with acute coronary syndromes (ACS). Stent thrombosis (ST) is a rare but serious complication of percutaneous coronary intervention (PCI). The Academic Research Consortium definition of ST excludes events occurring during PCI. Angiograms from the ACUITY (Acute Catheterization and Urgent Intervention Triage StrategY) and HORIZONS-AMI (Harmonizing Outcomes with RevascularIZatiON and Stents in Acute Myocardial Infarction) trials were reviewed frame-by-frame at an independent core laboratory for the occurrence of IPST. Patients with versus without IPST were compared to identify baseline characteristics associated with IPST and demonstrate the independent association between IPST and adjudicated events at 30 days and 1 year. Intra-procedural ST occurred in 47 (0.7%) of 6,591 patients. The occurrence of IPST was associated with ST-segment elevation myocardial infarction presentation, high white blood cell count, treatment of thrombotic and bifurcation lesions, bivalirudin monotherapy, bail-out IIb/IIIa inhibitor use, and implantation of bare-metal (rather than drug-eluting) stents. Major adverse ischemic events were markedly higher in patients with versus without IPST, including mortality at 30 days (12.9% vs. 1.4%, p definite or probable ST also occurred significantly more often among IPST patients at 30 days (17.4% vs. 1.8%, p < 0.0001) and 1 year (19.9% vs. 2.7%, p < 0.0001). Intra-procedural ST was a significant independent predictor of 1-year mortality (hazard ratio: 3.86, 95% confidence interval: 1.66 to 9.00, p = 0.002). Intra-procedural ST is a relatively rare complication of PCI in ACS but is strongly associated with subsequent out-of-lab ST and mortality. Intra-procedural ST should be considered as a distinct category of ST and routinely reported, particularly for ACS patients. Copyright © 2013 American College of Cardiology

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    The acute coronary syndrome is the most severe form of coronary artery disease. It is an immediate threat of life and the mortality rate can be high without proper therapy and patient management. Based on the first ECG, two different forms can be distinguished: acute coronary syndrome with and without ST elevation. Besides adequate medication, management of these patients is an essential part of treatment. In case of ST elevation, coronarography and percutaneous coronary intervention is needed in general, within 24 hours from the onset of symptoms. When ST elevation is not detected on the ECG, individual ischemic risk factors and predictable mortality of the patient may define the necessity and the date of the invasive examination. The Hungarian hemodynamic laboratory network covers almost the whole country and, therefore, practically each patient may receive a state-of-the-art therapy. Although indicators of cardiovascular diseases are still prominent, the mortality rate of myocardial Infarction is decreasing in Hungary due to the well-organized invasive care.

    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 Patients aged over 85 years have been under-represented in percutaneous coronary intervention (PCI)trials despite an increase in referrals for PCI. The long-term safety and efficacy of percutaneous coronary stenting in patients aged over 85 years with acute coronary syndrome (ACS) remain unclear. Moreover it is unknown whether there are differences between bare metal stent (BMS) and drug eluting stent (DES) in this special population.Methods A total of 80 patients with ACS aged over 85 years undergoing stenting (BMS group n=21 vs DES group n=59)were retrospectively studied. In-hospital, one year and overall clinical follow-up (12-36 months) of major adverse cardiac events (MACEs) including cardiac deaths, myocardial infarction, target lesion revascularization (TLR) and target vessel revascularization (TVR) as well as stroke and other major bleeding were compared between the two groups.Results In the entire cohort, the procedure success rate was 93.8% with TIMI-3 coronary flow post-PCI in 93.8% of the vessels and the procedure related complication was 17.5%. The incidence of in-hospital MACEs in BMS group was higher (14.3% vs 6.8%, P=0.30). The 1-year incidence of MACEs in DES group was 7.0% while there was no MACE in the BMS group. Clinical follow-up for 12-36 months showed that the overall survival free from MACE was 82.9% and the incidence of MACE in the BMS group was lower (5.3% vs 21.1%, P=0.20). Multivariate regression analysis showed that the creatinine level (OR:1.013; 95%C1: 1.006-1.020; P=0.004) and hypertension (OR:3.201; 95%C1: 1.000-10.663;P=0.04) are two major factors affecting the long-term MACE.Conclusions Percutaneous coronary stenting in patients aged over 85 years is safe and provides good short and long-term efficacy. Patients with renal dysfunction and hypertension may have a relatively high incidence of MACE.

    Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; ppiracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; ppiracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (pPiracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass. It reduces an early postoperative substantial decline of neuropsychological abilities.

    Abstract The plasma levels of asymmetric dimethylarginine (ADMA) had been proved to be an independent cardiovascular risk factor. Few studies involved the entire arginine methylation dysfunction. This study was designed to investigate whether arginine methylation dysfunction is associated with acute coronary syndrome risk in coronary artery disease population. In total 298 patients undergoing coronary angiography because of chest pain with the diagnosis of stable angina pectoris or acute coronary syndrome from February 2013 to June 2014 were included. Plasma levels of free arginine, citrulline, ornithine, and the methylated form of arginine, ADMA, and symmetric dimethylarginine (SDMA) were measured with high-performance liquid chromatography coupled with tandem mass spectrometry. We examined the relationship between arginine metabolism-related amino acids or arginine methylation index (AMI, defined as ratio of [arginine + citrulline + ornithine]/[ADMA + SDMA]) and acute coronary events. We found that plasma ADMA levels were similar in the stable angina pectoris group and the acute coronary syndrome group (P = 0.88); the AMI differed significantly between 2 groups (P angina and acute coronary syndrome patients; AMI might be an independent risk factor of acute coronary events in coronary artery disease population.

    BACKGROUND: Congenital heart disease, primarily involving the left-sided structures, is often seen in patients with Turner Syndrome. Moreover, a few case reports have indicated that coronary anomalies may be more prevalent in Turner Syndrome than in the normal population. We therefore set out...... to systematically investigate coronary arterial anatomy by computed tomographic coronary angiography (coronary CTA) in Turner Syndrome patients. METHODS: Fifty consecutive women with Turner Syndrome (mean age 47 years [17-71]) underwent coronary CTA. Patients were compared with 25 gender-matched controls. RESULTS......: Coronary anomaly was more frequent in patients with Turner Syndrome than in healthy controls [20% vs. 4% (p = 0.043)]. Nine out of ten abnormal cases had an anomalous left coronary artery anatomy (absent left main trunk, n = 7; circumflex artery originating from the right aortic sinus, n = 2). One case had...

    Superior vena cava syndrome is the obstruction of the superior vena cava or its main tributaries by benign or malignant lesions. The syndrome causes edema and engorgement of the vessels on the face, neck, and arms, nonproductive cough, and dyspnea. We discuss the case of a 48-year-old obese diabetic woman who was admitted with unstable angina. She had previously been diagnosed with superior vena cava syndrome. Urgent coronary artery bypass grafting was necessary Although thousands of coronary artery bypasses are performed every year, there are not many reports on patients with superior vena cava syndrome who successfully undergo cardiopulmonary bypass and coronary artery grafting with an internal mammary artery as the conduit. The results of the case and alternative recommended methods are discussed.

    Full Text Available Abstract Preoperative medication by inhibitors of angiotensin-converting enzyme (ACE in coronary artery patients predisposes to vasoplegic shock early after coronary artery bypass grafting. Although in the majority of the cases this shock is mild, in some of them it appears as a situation, "intractable" to high-catecholamine dose medication. In this study we examined the possible role of prophylactic infusion of low-dose vasopressin, during and for the four hours post-bypass after cardiopulmonary bypass, in an effort to prevent this syndrome. In addition, we studied the influence of infused vasopressin on the hemodynamics of the patients, as well as on the postoperative urine-output and blood-loss. In our study 50 patients undergoing coronary artery bypass grafting were included in a blind-randomized basis. Two main criteria were used for the eligibility of patients for coronary artery bypass grafting: ejection fraction between 30-40%, and patients receiving ACE inhibitors, at least for four weeks preoperatively. The patients were randomly divided in two groups, the group A who were infused with 0.03 IU/min vasopressin and the group B who were infused with normal saline intraoperativelly and for the 4 postoperative hours. Measurements of mean artery pressure (MAP, central venous pressure (CVP, systemic vascular resistance (SVR, ejection fracture (EF, heart rate (HR, mean pulmonary artery pressure (MPAP, cardiac index (CI and pulmonary vascular resistance (PVR were performed before, during, and after the operation. The requirements of catecholamine support, the urine-output, the blood-loss, and the requirements in blood, plasma and platelets for the first 24 hours were included in the data collected. The incidence of vasodilatory shock was significantly lower (8% vs 20% in group A and B respectively (p = 0,042. Generally, the mortality was 12%, exclusively deriving from group B. Postoperatively, significant higher values of MAP, CVP, SVR and EF

    Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

    Objective: To study therapeutic effects and safety of domestic clopidogrel in patients with non -ST segment elevation acute coronary syndrome (NSTEACS) who underwent emergency percutaneous coronary intervention (PCI). Methods: A total of 176 NSTEACS patients underwent emergency PCI were divided into domestic clopidogrel group (received talcom, n=89) and import clopidogrel group (received plavix, n=87). Before PCI the two groups were respectively given domestic or import clopidogrel 600mg; after PCI were respectively given 75mg every day for over one year. Therapeutic effects and occurrence of adverse reactions were observed in the two groups. Results: There were no significant difference in complete revascularization rate (79. 8% vs. 89. 3% , P=0. 477) , major adverse cardiovascular-cerebral events (MACCE) (9. 0% vs. 6. 9% , P = 0. 608) , occurrence rates of adverse reactions (5. 6% vs. 8. 0% , P=0. 523) between domestic clopidogrel group and import clopidogrel group. Conclusion: Domestic clopidogrel (Talcom) is as safe and effective as import clopidogrel in treatment of acute non-ST segment elevation acute coronary syndrome.%目的:研究国产氯吡格雷用于非ST段抬高急性冠脉综合征(NSTEACS)急诊经皮冠脉介入(PCI)治疗患者的疗效及安全性.方法:确诊NSTEACS并接受急诊PCI的患者176例,分成国产氯吡格雷组(接受泰嘉治疗,89例)和进口氯吡咯雷组(接受波立维治疗,87例).PCI治疗前两组分别接受泰嘉、波立维每日600mg.PCI后每日分别接受75mg至1年以上.观察两组患者的疗效及不良反应的发生情况.结果:国产氯吡格雷组与进口氯吡格雷组达到的完全血运重建率(79.8%比89.3%,P=0.477),主要不良心脑血管事件(MACCE)发生率(9.0%比6.9%,P=0.608),不良反应的发生率(5.6%比8.0%,P=0.523)均无显著差异.结论:国产氯吡格雷(泰嘉)治疗急性非ST段抬高心肌梗死的疗效和安全性与进口氯吡格雷相当.

    Contrast-induced nephropathy (CIN) impairs clinical outcome in patients undergoing angiographic procedures. The aim of this study was to investigate whether short-term high-dose atorvastatin load decreases the incidence of CIN after percutaneous coronary intervention (PCI). Statin-naive patients with acute coronary syndrome undergoing PCI (n = 241) randomly received atorvastatin (80 mg 12 hours before intervention with another 40-mg preprocedure dose, n = 120) or placebo (n = 121). All patients had long-term atorvastatin treatment thereafter (40 mg/day). Primary end point was incidence of CIN defined as postintervention increase in serum creatinine ≥0.5 mg/dl or >25% from baseline. Five percent of patients in the atorvastatin arm developed CIN versus 13.2% of those in the placebo arm (p = 0.046). In the atorvastatin group, postprocedure serum creatinine was significantly lower (1.06 ± 0.35 vs 1.12 ± 0.27 mg/dl in placebo, p = 0.01), creatinine clearance was decreased (80.1 ± 32.2 vs 72.0 ± 26.6 ml/min, p = 0.034), and C-reactive protein peak levels after intervention were decreased (8.4 ± 10.5 vs 13.1 ± 20.8 mg/l, p = 0.01). Multivariable analysis showed that atorvastatin pretreatment was independently associated with a decreased risk of CIN (odds ratios 0.34, 95% confidence interval 0.12 to 0.97, p = 0.043). Prevention of CIN with atorvastatin was paralleled by a shorter hospital stay (p = 0.007). In conclusion, short-term pretreatment with high-dose atorvastatin load prevents CIN and shortens hospital stay in patients with acute coronary syndrome undergoing PCI; anti-inflammatory effects may be involved in this renal protection. These results lend further support to early use of high-dose statins as adjuvant pharmacologic therapy before percutaneous coronary revascularization. Copyright © 2011 Elsevier Inc.

    The study sought to compare clinical outcomes in a contemporary acute coronary syndrome (ACS) percutaneous coronary intervention (PCI) cohort stratified by chronic kidney disease (CKD) status. Patients with CKD exhibit high risks for both thrombotic and bleeding events, thus complicating decision making regarding antiplatelet therapy in the setting of ACS. The PROMETHEUS study was a multicenter observational study comparing outcomes with prasugrel versus clopidogrel in ACS PCI patients. Major adverse cardiac events (MACE) at 90 days and at 1 year were defined as a composite of death, myocardial infarction, stroke, or unplanned revascularization. Clinically significant bleeding was defined as bleeding requiring transfusion or hospitalization. Cox regression multivariable analysis was performed for adjusted associations between CKD status and clinical outcomes. Hazard ratios for prasugrel versus clopidogrel treatment were generated using propensity score stratification. The total cohort included 19,832 patients, 28.3% with and 71.7% without CKD. CKD patients were older with greater comorbidities including diabetes and multivessel disease. Prasugrel was less often prescribed to CKD versus non-CKD patients (11.0% vs. 24.0%, respectively; p < 0.001). At 1 year, CKD was associated with higher adjusted risk of MACE (1.27; 95% confidence interval: 1.18 to 1.37) and bleeding (1.46; 95% confidence interval: 1.24 to 1.73). Although unadjusted rates of 1-year MACE were lower with prasugrel versus clopidogrel in both CKD (18.3% vs. 26.5%, p < 0.001) and non-CKD (10.9% vs. 17.9%; p < 0.001) patients, associations were attenuated after propensity stratification. Similarly, unadjusted differences in 1-year bleeding with prasugrel versus clopidogrel (6.0% vs. 7.4%, p = 0.18 in CKD patients; 2.6% vs. 3.5%, p = 0.008 in non-CKD patients) were not significant after propensity score adjustment. Although risks for 1-year MACE were significantly higher in ACS PCI patients with

The focus of our review was the relative use of effective treatments in patients with coronary angiographic evidence of obstructive coronary disease, defined as a lumen stenosis >50% of the adjacent non-diseased arterial diameter. We searched MEDLINE, and the Cochrane Database between January 1998 and May 2008. Only a few of the published clinical registries on ACS provide data on treatments dichotomized by confirmed coronary angiographic disease. Consequently, we also accessed individual patient-level data from 3 established ACS registries: the Finnish TACOS (Tampere Acute COronary Syndrome), the British EMMACE 2 (Evaluation of Methods and Management of Acute Coronary Events) and the Argentine PACS-ITALSIA (Prognosis in Acute Coronary Syndromes and the ITALian hospital Sindrome Isquemico Agudo). Despite presenting with higher risk characteristics and having higher in-hospital and 6 months risk of death, women with ACS and obstructive coronary artery disease were apparently treated less aggressively with secondary preventive drugs than were men, being less likely to receive aspirin, beta-blockers and statins at discharge. Overall, coronary revascularization appears to be performed in a similar proportion of women and men - once angiography has been performed and the coronary anatomy is known. However, substantial geographic variation exists in the relative rate of coronary angiography in men and women. In United Kingdom coronary revascularization tends to be done less frequently in women. Our study, therefore, demonstrates a gender bias in the delivery of secondary drug treatments for ACS, even for patients with documented significant coronary disease.

    We present a case of 73 year-old patient who underwent coronary angiography due to suspicion of acute coronary syndrome without persistent ST segment elevation. The angiographic result showed no lesions that could cause recurrent chest pain,but it also revealed a seldom coronary artery abnormality - left coronary artery arising from right coronary sinus. Performed computed tomography of the chest confirmed the result of the coronarography. But apart from that it found the signs of neoplastic disease which was probably responsible for clinical presentation.

    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.

  3. Acute Coronary Syndrome and ST Segment Monitoring.

    Acute coronary syndrome (ACS) is caused by a critical obstruction of a coronary artery because of atherosclerotic coronary artery disease. Three specific conditions are included: ST elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. The ST segment on the electrocardiogram is a sensitive and specific marker of myocardial ischemia and infarction; however, ST segment deviation is regional not global, thus the ECG lead must be placed over the affected region of the myocardium. This article describes ACS and infarction and the use of ST segment monitoring to detect these conditions.

    Full Text Available Acute pancreatitis is an inflammatory syndrome with unpredictable progression to systemic inflammation and multi-organ dysfunction. As in our case rarely, acute pancreatitis can be presented with the coexistance of acute coronary syndrome. To prevent a misdiagnosis of acute situation presented with chest or abdominal pain, physicians must be aware for coexisting pathophysiologies and take into account the differential diagnosis of all life-threatening causes such as cardiac ischemia or acute abdominal situations.

    @@atients with Acute Coronary Syndrome (ACS)are a clinical continuum-with patients presenting with unstable angina on one end, with patients with ST elevation myocardial infarction (STEMI) at the other end of the spectrum. In between are those with non- ST elevation myocardial infarction (NSTEMI) The pathophysiology is similar in these patients, namely isruption and fissuring of an atheromatous plaque,leading to enhanced platelet activation and local vasohyperactivity, with reduced flow and thrombus formation. While medical experts have reached consensus in the management of STEMI patients (thrombolysis nd / or percutaneous coronary intervention), optimalmanagement of patients with UA/NSTEMI remainsunclear.

    Full Text Available Background and aims: Cardiovascular disease (CVD is the leading cause of death in the Middle East. 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 Significant left main coronary artery (LMCA stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES, extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion. However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI. In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management.

    Objective: To explore the relationship of Traditional Chinese Medicine (TCM) Syndrome type and coronary arteriography (CAG) with respect to the number and degree of stenosed branches of coronary artery (CA) and ACC/AHA stage of acute coronary syndrome (ACS), to provide an objective evidence for TCM Syndrome typing on ACS.Methods: Ninety patients of ACS with their TCM Syndrome typing and CAG successfully conducted were enrolled in this study. They were classified into 3 Syndrome types, the blood stasis type (typeⅠ), the phlegm stagnant with blood stasis type (typeⅡ), and the endogenous collateral Wind type (typeⅢ). The scores of the number and severity of the stenosis branch of CA and ACC/AHA lesion stage in different Syndrome types were calculated respectively and analysed statistically by Ridit analysis.Results: The number of stenosed branches increased gradually with the Syndrome type changing from Ⅰ→Ⅱ→Ⅲ, compared the type Ⅲ with the other two types(P<0.01). The severity of stenosis in typeⅠ and Ⅱ were similar, but that of Type Ⅲ, much aggravated was significantly different from that in the former two (P<0.01). The ACC/AHA stage of coronary lesion tended to be more complex as the Syndrome type changed, patients of TCM typeⅠ and Ⅱ had mostly lesion of stage A or B1 , while lesion in majority of patients of type Ⅲ belonged to stage B2 or C, comparison between the three types showed significant difference (P<0.01). Conclusion: Most ACS patients of TCM Syndrome type Ⅲ with tri-branch, severe stenosed coronary arteries, belong to the complex ACC/AHA stage of B2 and C.

    Aim of this study was to compare the outcome of beating heart versus conventional coronary artery bypass graft (CABG) strategies in acute coronary syndromes for emergency indications. 638 consecutive patients with acute coronary syndrome (ACS) receiving emergency CABG surgery via midline sternotomy from January 2000 to September 2005 were evaluated. Propensity score analysis was used to predict the probability of undergoing beating heart (BH) (n=240) versus cardioplegic cardiac arrest (CA) (n=398) strategies. Patients presented with stable hemodynamics (n=531) or in cardiogenic shock (CS) (n=107). Hospital and follow-up outcome was compared by propensity score adjusted multiregression analysis. BH included 116 on-pump and 124 off-pump (OPCAB) procedures. There was a propensity to operate CS patients on the beating heart (multivariate odds ratio [OR], 3.8; P=0.001). Under stable hemodynamics significant predictors for BH selection were logEuroSCORE >20% (OR, 2.05), creatinine >1.8 mg/dL (OR, 4.12), complicated percutaneous coronary intervention (OR, 1.88), ejection fraction coronary syndrome with or without CS.

    We studied effect of time on the outcome of acute coronary syndrome and elevated ST segment at the prehospital stage. Logistic regression analysis revealed two time-dependent predictors: "symptom-needle" time and total call service time. In patients undergoing prehospital thrombolysis, these indices (88 and 85 min respectively) reliably predicted the probability of fatal outcome. Their values of 71 and 77 min respectively predicted the risk of unfavourable outcome. The total call service time may serve as an indicator of the quality of work of an ambulance crew at the prehospital stage of management of acute coronary syndrome with elevated ST segment.

    This study aimed to compare the clinical and economic outcomes of pharmacogenetic-guided (PG-guided) and platelet reactivity testing-guided antiplatelet therapy for patients with acute coronary syndrome undergoing percutaneous coronary intervention. A decision-analytic model was simulated including four antiplatelet strategies: universal clopidogrel 75 mg daily, universal alternative P2Y12 inhibitor (prasugrel or ticagrelor), PG-guided therapy, and platelet reactivity testing-guided therapy. PG-guided therapy was the preferred option with lowest cost (US$75,208) and highest quality-adjusted life years gained (7.6249 quality-adjusted life years). The base-case results were robust in sensitivity analysis. PG-guided antiplatelet therapy showed the highest probability to be preferred antiplatelet strategy for acute coronary syndrome patients with percutaneous coronary intervention.

    2017-01-01

    Highly active antiretroviral treatment (HAART) has considerably increased the life expectancy of patients infected with HIV. Coronary artery disease is a leading cause of mortality in patients infected with HIV. This is primarily attributed to their increased survival, HAART-induced metabolic derangements, and to HIV itself. The pathophysiology of atherosclerosis in HIV is both multifactorial and complex – involving direct endothelial injury and dysfunction, hypercoagulability, and a significant contribution from traditional cardiac risk factors. The advent of HAART has since heralded a remarkable improvement in outcomes, but at the expense of other unforeseen issues. It is thus of paramount importance to swiftly recognize and manage acute coronary syndromes in HIV-infected patients to attenuate adverse complications, which should translate into improved clinical outcomes.

    Objective To summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.Data sources A literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.Study selection Well-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.Data extraction Data and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.Data synthesis Inflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.Conclusions Inflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin Ⅱ receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein Ⅱb/Ⅲa receptor antagonists, mechanical intervention strategies, etc).

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 trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

    Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

    Contrast-induced nephropathy (CIN) is a complex syndrome of acute kidney injury induced by exposure to intravascular contrast media. CIN occurs frequently in patients undergoing urgent percutaneous coronary intervention (PCI) and is associated with poor outcomes, making it a major challenge faced by interventional cardiologists. It has been suggested that female sex is a risk factor for development of CIN following PCI. However, no data exist in the literature concerning the risks of postmenopausal women with acute myocardial infarction (AMI) developing CIN after undergoing urgent PCI. To explore the incidence, risk factors and in-hospital outcomes of CIN in this special population, we analyzed 69 postmenopausal women with AMI treated with urgent PCI. CIN was defined as a relative increase of >25% or an absolute increase of >or=0.5 mg/dL in serum creatinine concentration from the baseline value 72 h after exposure to contrast medium. We found 1) the incidence of CIN was 37.68%; 2) patients with CIN had worse in-hospital outcomes, including longer hospital stay and more in-hospital adverse events; and 3) in multivariate logistic analysis, independent risk factors for CIN included a longer menopausal duration and the implantation of an intra-aortic balloon pump (an indirect indicator of hemodynamic instability). These results indicate that CIN is a frequent complication associated with worse in-hospital outcomes in postmenopausal women with AMI who are undergoing urgent PCI, particularly those with longer menopausal duration and hemodynamic instability. It is therefore necessary to pay more attention to preventive strategies for renal protection in this special population.

    Cognitive impairments are observed in numerous patients following coronary bypass surgery, and piracetam are nootropic compounds that modulate cerebral functions by directly enhancing cognitive processes. The present meta-analysis was conducted to evaluate the protective effect of piracetam on the cognitive performance of patients undergoing coronary bypass surgery. The relevant studies were identified by searching Medline, EMBASE, PubMed and the Cochrane Library up to June 2013 and the pertinent bibliographies from the retrieved studies were reviewed. Data were selected from the studies according to predefined criteria. The meta-analysis included two randomized control trials involving 184 patients and including the Syndrom-Kurz test (SKT). Findings of the meta-analysis showed that following treatment the change from baseline observed in five SKT subtest scores, conducted with piracetam patients, indicated a significant advantage over those patients that were in the placebo group. The subtests included immediate pictured object recall, weighted mean difference (WMD)=0.91, 95% confidence interval (CI) 0.51–1.31, Ppiracetam may have been effective in improving the short-term cognitive performance of patients undergoing coronary bypass surgery. High quality, well-controlled and longer randomized trials are required to corroborate this result. PMID:24396419

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

    Stiff person syndrome (SPS) is a rare neuroimmunological disorder characterized by severe progressive muscle stiffness in axial and lower extremity musculature with superimposed painful muscle spasms. Although chest pain is a common reason for SPS patients presenting to the emergency room, this disorder is overlooked and not part of the differential diagnosis of chest pain. Herein, we report on a middle age male presenting with classic symptoms of SPS; however, due to the rarity of this disease, he was initially thought to have acute coronary syndrome. Clinicians should consider the diagnosis of SPS in patients with fluctuating muscle spasms in the torso and/or extremities in the setting of repeated hospitalizations without subsequent symptom relief.

    Full Text Available Harm Wienbergen, Uwe ZeymerHerzzentrum Ludwigshafen, Medizinische Klinik B, GermanyAbstract: Fondaparinux is the first selective inhibitor of the coagulation factor Xa which is commercially avaliable for clinical use. It has been approved for the prevention of venous thromboembolism in patients undergoing orthopedic surgery and for the initial therapy of venous thromboembolism. In randomized clinical trials the value of fondaparinux in the treatment of ST-elevation myocardial infarction (STEMI has been investigated. The PENTALYSE study showed that fondaparinux was at least as effective and safe as unfractionated heparin in 333 patients with STEMI undergoing fibrinolysis with t-PA. In the recent large OASIS-6 trial with 12,092 patients the treatment with 2.5 mg fondaparinux daily significantly reduced death and reinfarctions until day 30 compared with guideline recommended usual care and compared with unfractionated heparin (9.7% vs 11.2%, p = 0.008 without increasing major bleedings (1.0% vs 1.3%, p = 0.13. This advantage was predominantly seen in the subgroups of patients with fibrinolysis and without early reperfusion therapy. However, in the subgroup of primary percutaneous coronary interventions (PCIs no clinical benefit of fondaparinux was found, but there were more catheter thrombosis and acute thrombotic complications. In summary, fondaparinux is a new antithrombin that is an efficient, safe, and easy to use in treatment for STEMI patients, particularly those not undergoing primary PCI.Keywords: selective factor Xa inhibition, fondaparinux, acute ST-elevation myocardial infarction, antithrombin therapy

    Background Only a small proportion of patients referred for coronary angiography with suspected coronary artery disease (CAD) have the diagnosis of obstructive CAD confirmed by the exam. For this reason, further strategies for risk stratification are necessary. Objective To investigate the relationship of the presence of fragmented QRS (fQRS) on admission electrocardiogram with angiographically detected CAD and CAD severity in patients without known vascular diseases and myocardial fibrosis, undergoing first diagnostic coronary angiography. Methods We enrolled 336 consecutive patients undergoing coronary angiography for suspected CAD. The patients were divided into two groups according to the presence or absence of fQRS on admission. We compared the groups regarding the presence and severity of CAD. Results Seventy-nine (23.5%) patients had fQRS on admission. There was not a statistically significant difference between patients with fQRS (41.8%) and non-fQRS (30.4%), regarding the presence of CAD (p = 0.059). However, there was a statistically significant difference between patients with fQRS and non-fQRS regarding the presence of stenotic CAD (40.5% vs. 10.5%, p22 compared to patients with SYNTAX score ≤22. Conclusions Our findings suggest that fQRS may be an indicator of early-stage myocardial damage preceding the appearance of fibrosis and scar, and may be used for risk stratification in patients undergoing first diagnostic coronary angiography PMID:27849256

    Aspirin and clopidogrel are proven to prevent thromboembolic events during percutaneous coronary intervention (PCI). Enzyme release of creatine kinase-MB (CK-MB) enzyme during PCI has been associated with an increased risk of future adverse cardiac events. This study examined the correlation between measurements of aspirin resistance and the level of inhibition of the thienopyridine-specific P2Y12 platelet receptor and CK-MB release after PCI. We prospectively studied 330 patients with elective PCI treated with drug-eluting stents. Patients were pretreated with aspirin and clopidogrel. Patients with positive CK-MB or acute coronary syndrome and those on glycoprotein IIb/IIIa inhibitors were excluded. Serum assays of aspirin resistance (Ultegra Rapid Platelet Function Assay-ASA, Accumetrics) and clopidogrel resistance (Rapid Platelet Function Assay P2Y12, Accumetrics) were performed before PCI. Serum troponinI and CK-MB levels were measured at 8, 16, and 24 hours after PCI. Aspirin resistance unit (ARU) measurement > or =550 was detected in 12 patients (3.7%). Mean platelet reactivity unit (PRU; measurement of inhibition of P2Y12 activity) was 192.2 +/- 95.4 (lower PRU, more inhibition of P2Y12 receptor). There was no correlation between level of ARU or PRU and troponin I or CK-MB release after PCI at any time point. Only multivessel coronary disease was found to be a predictor of any increase in CK-MB in a multivariate analysis (odds ratio 2.2, 95% confidence interval 1.4 to 3.3, p = 0.0003). A positive correlation was found between levels of ARU and PRU. Target vessel revascularization/major adverse cardiac event rate at 6 months was 8.2% with no correlation between ARU or PRU and release of cardiac enzymes or occurrence of adverse cardiac events. In conclusion, this study does not support routine measurements of aspirin and clopidogrel resistance in stable patients undergoing PCI.

    The study aimed to examine the association between incidentally discovered mesenteric artery stenosis, renal artery stenosis (RAS) and coronary artery disease in patients undergoing coronary angiography. We performed a prospective analysis of consecutive patients undergoing routine cardiac catheterisation. Abdominal aortograms in lateral and antero-posterior view were obtained to assess arterial stenosis of the coeliac axis, superior mesenteric artery and renal arteries. Significant arterial stenosis was defined as a narrowing of at least 50% compared with the normal artery. Demographic data and cardiovascular risk factors were analysed. The prevalence of visceral artery stenosis (VAS) was 63/450 (14%) including 48/450 (10.6%) cases of coeliac axis stenosis and 15/450 (3.3%) cases of superior mesenteric artery stenosis. Female sex (p = 0.01), older age (p = 0.03) and the presence of coronary artery disease (p = 0.05) were significant predictors for the presence of VAS in univariate analysis. The determinants for VAS in multivariate analysis were female sex and three-vessel coronary artery disease, while two- and three-vessel coronary artery disease was significant for RAS. Screening for VAS and RAS in female patients older than 60 years with more than two diseased coronary segments could have a high diagnostic value.

    Full Text Available A painful mononeuropathy of the lateral femoral cutaneous nerve (LFCN, meralgia paresthetica is commonly due to focal entrapment of this nerve as it passes through the inguinal ligament. Rarely, it has other etiologies such as direct trauma, stretch injury, or ischemia. Transfemoral Coronary Angiography is the rare cause of this condition.
    We diagnosed 5 patients with this syndrome from 1998-1999 as a complication of angiography. Four patients were male. Diagnosis was confirmed by physical exam and diagnostic tests (NCV, EMG. This syndrome typically occurs in isolation. The clinical history and examination is usually sufficient for making the diagnosis. However, the diagnosis can be confirmed by nerve conduction studies. Treatment is usually supportive. The LFCN is responsible for the sensation of the anterolateral, thigh. It is a purely sensory nerve and has no motor component.
    The clinical syndrome is well defined, and further evaluation by electrodiagnostic .studies may be unnecessary. Evaluation with nerve conduction studies and needle examination electromyography (EMG is warranted if no risk factors are identified, if a mass lesion in the retroperitoneal space is suspected, or if back pain also is present.
    LFCN conduction studies can be technically difficult. When obtained, compare with the asymptomatic side.The EMG should be normal in LFCN lesions, but the test is helpful in ruling out upper lumbar radieulopathy. Removing the cause of compression is the best therapy. In some patients, this entails weight loss and wearing loose clothing. Most patients with meralgia paresthetica will have mild symptoms that respond to conservative management.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    The increasing population in older age will lead to greater numbers of them presenting with acute coronary syndromes (ACS). This has implications on global healthcare resources and necessitates better management and selection for evidenced-based therapies. The elderly are a high risk group with more significant treatment benefits than younger ACS. Nevertheless, age related inequalities in ACS care are recognised and persist. This discrepancy in care, to some extent, is explained by the higher frequency of atypical and delayed presentations in the elderly, and less diagnostic electrocardiograms at presentation, potentiating a delay in ACS diagnosis. Under estimation of mortality risk in the elderly due to limited consideration for physiological frailty, co-morbidity, cognitive/psychological impairment and physical disability, less input by cardiology specialists and lack of randomised, controlled trials data to guide management in the elderly may further confound the inequality of care. While these inequalities exist, there remains a substantial opportunity to improve age related ACS outcomes. The selection of elderly patients for specific therapies and medication regimens are unanswered. There is a growing need for randomised, controlled trial data to be more representative of the population and enroll those of advanced age with co-morbidity. A lack of reporting of adverse events, such as renal impairment post coronary angiography, in the elderly further limit risk benefit decisions. Substantial improvements in care of elderly ACS patients are required and should be advocated. Ultimately, these improvements are likely to lead to better outcomes post ACS. However, the improvement in outcome is not infinite and will be limited by non-modifiable factors of age-related risk.

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application.

    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.

    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 Abstract Background Studies in patients with low HDL have suggested that impaired cellular cholesterol efflux is a heritable phenotype increasing atherosclerosis risk. Less is known about the association of macrophage cholesterol efflux with lipid profiles and CAD risk in normolipidemic subjects. We have therefore measured macrophage cholesterol efflux in142 normolipidemic subjects undergoing coronary angiography. Methods Monocytes isolated from blood samples of patients scheduled for cardiac catheterization were differentiated into macrophages over seven days. Isotopic cholesterol efflux to exogenously added apolipoprotein A-I and HDL2 was measured. Quantitative cholesterol efflux from macrophages was correlated with lipoprotein subclass distribution in plasma from the same individuals measured by NMR-spectroscopy of lipids and with the extent of coronary artery disease seen on coronary angiography. Results Macrophage cholesterol efflux was positively correlated with particle concentration of smaller HDL and LDL particles but not with total plasma concentrations of HDL or LDL-cholesterol. We observed an inverse relationship between macrophage cholesterol efflux and the concntration of larger and triglyceride rich particles (VLDL, chylomicrons. Subjects with significant stenosis on coronary angiography had lower cholesterol efflux from macrophages compared to individuals without significant stenosis (adjusted p = 0.02. Conclusion Macrophage cholesterol efflux is inversely correlated with lipoprotein particle size and risk of CAD.

    pulmonary emphysema. Because the worsening of ECG changes she was transferred to Coronary unit. The diagnosis of non-Q myocardial infarction was confirmed and treatment with nitrates and beta-adrenergic antagonists was instituted. Four weeks later she became euthyroid and coronarography was performed. Subepicardial coronary arteries were normal (Figure 1. She was dismissed, and still euthyroid three months later. DISCUSSION Agranulocytosis is very rare but very serious complication of antithyroid drug therapy. It can be detected in about 0.1 -1 % patients during the first three months of treatment. Sudden appearance, heralded by sore throat and fever, prompt physicians to seek white blood cell and differential count [1-3]. Confirmation of diagnosis urges cessation of drug therapy and appropriate antibiotic treatment. Recently, it was reported that recombinant human granulocyte colony-stimulating factor (rhG-CSF is to be effective in shortening the recovery time in the neutropenic patients undergoing chemotherapy and also in patients with other types of neutropenia [5]. Tamai at al. [7] confirmed positive outcome in 34 patients treated with rhG-CSF compared to corticosteroid treatment. Hematologic laboratory abnormalities disappear 7-10 days after secession of therapy. Patients completely recover two to three weeks later. Fatal outcome was also described [1 -5]. Thyroid hormones have profound effects on cardiovascular physiology, especially on heart rate, cardiac output and systemic vascular resistance. In patients with hyperthyroidism, cardiac output is much higher than in normal persons. This is the result of direct effect of thyroid hormones on cardiac muscle contractility, heart rate and decrease in systemic vascular resistance. Excessive thyroid hormone secretion increases cardiac Na-K-activated plasma membrane ATP-ase and sarcoplasmic reticulum Ca-activated ATP-ase with resultant in increase myocardial contractility [6 9]. Sinus tachycardia is the most common rhythm

    Since the drug eluting stents appeared in Japan, the indication for percutaneous coronary intervention has become wide-spread for the treatment of coronary artery disease. In the past decade, 216 patients underwent emergency/urgent coronary artery bypass grafting (CABG) in our institution, while the annual numbers of both emergency and elective CABG cases have declined. On the contrary to the decreasing number, emergency CABG patients were significantly getting older with multiple co-morbidities. Thus, off-pump CABG is likely to be beneficial for preventing postoperative complications, leading to the decreased postoperative mortality. When emergency CABG patients developed refractory myocardial ischemia and unstable hemodynamics, a percutaneous cardiopulmonary support system was quickly applicable and useful for on-pump beating CABG achieving complete surgical revascularization. For keeping satisfactory hemodynamics during CABG, communication between cardiovascular surgeons, anesthesiologists, and perfusionists is most important.

    The occurrence of an anastomosis between the coronary artery to the systemic artery is rare. However, the probability of hemodynamic changes sufficient to cause clinical symptoms is extremely low. Anastomosis of the coronary to bronchial artery can cause myocardial ischemia due to the decreased flow to the coronary arteries. The authors report a case of coronary to bronchial artery anastomosis presenting as coronary steal syndrome that was treated with transarterial microcoil embolization instead of surgical ligation.

    Epicardial coronary arteries are normal in patients with cardiac syndrome X. It is, however, unclear whether there is an abnormality at the level of microvascular circulation. In this study, our aim was to evaluate the epicardial coronary blood flow and myocardial perfusion in patients with cardiac syndrome X. Two hundred and three patients (mean age 53+/-10 years, 85 men) were included in the study. The diagnosis of cardiac syndrome X was made in patients who had a complaint of typical anginal chest pain and had ischemic findings on either myocardial perfusion scintigraphy or a treadmill exercise test, and whose coronary angiograms did not reveal any pathology. Fifty patients (mean age 54+/-11 years, 24 men) who had a complaint of typical anginal chest pain and had a normal myocardial perfusion test and normal coronary arteries were recruited as the control group. Epicardial coronary blood flow was evaluated with the thrombolysis in myocardial infarction frame count method and myocardial perfusion was evaluated with the myocardial blush grade method. A myocardial blush grade of 0.05). We found that the epicardial coronary blood flow, as assessed by thrombolysis in myocardial infarction frame count, and myocardial perfusion, as assessed by myocardial blush grade, were normal in patients with cardiac syndrome X.

    In patients with acute coronary syndromes undergoing percutaneous coronary intervention (PCI), the diagnosis of periprocedural myocardial infarction is often problematic when the pre-PCI levels of cardiac troponin T (TnT) are elevated. Thus, we examined different TnT criteria for periprocedural myocardial infarction when the pre-PCI TnT levels were elevated and also the associations between the post-PCI cardiac marker levels and outcomes. We established the relation between the post-PCI creatine kinase-MB (CKMB) and TnT levels in 582 patients (315 with acute coronary syndromes and 272 with stable coronary heart disease). A post-PCI increase in the CKMB levels to 14.7 μg/L (3 × the upper reference limit [URL] in men) corresponded to a TnT of 0.23 μg/L. In the 85 patients with acute coronary syndromes and normal CKMB, but elevated post peak TnT levels before PCI (performed at a median of 5 days, interquartile range 3 to 7), the post-PCI cardiac marker increases were as follows: 21 (24.7%) with a ≥ 20% increase in TnT, 10 (11.8%) with an CKMB level >3 × URL, and 12 (14%) with an absolute TnT increase of >0.09 μg/L (p 3× URL compared to those without markers elevations, the rate of freedom from death or nonfatal myocardial infarction was 88% for those with TnT elevations versus 99% (p 3× URL. Also, periprocedural cardiac marker elevations in patients with acute coronary syndromes did not have prognostic significance.

    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.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Epidemiologic evidence suggests a link between psychosocial risk factors such as marital status and coronary artery disease (CAD). Polygamy (multiple concurrent wives) is a distinct marital status practiced in many countries in Asia and the Middle East, but its association with CAD is not well defined. We conducted a multicenter, observational study of consecutive patients undergoing coronary angiography during the period from April 1, 2013, to March 30, 2014. Of 1,068 enrolled patients, 687 were married men. Polygamy was reported in 32% of married men (1 wife: 68%, 2 wives: 19%, 3 wives: 10%, and 4 wives: 3%). When stratified by number of wives, significant baseline differences were observed in age, type of community (rural versus urban), prior coronary artery bypass grafting (CABG), and household income. After adjusting for baseline differences, there was a significant association between polygamy and CAD (adjusted OR 4.6 [95% CI 2.5, 8.3]), multivessel disease (MVD) (adjusted OR 2.6 [95% CI 1.8, 3.7]), and left main disease (LMD) (adjusted OR 3.5 [95% CI 2.1, 5.9]). Findings were consistent when the number of wives was analyzed as a continuous variable. In conclusion, among married men undergoing coronary angiography for clinical indications, polygamy is associated with the presence of significant CAD, MVD, and LMD. PMID:28250991

    Coronary artery ectasia(CAE)often represents a coronary angiography finding casually detected or following the occurrence of an acute coronary syndrome.The pathogenetic role of cocaine abuse in the genesis of CAE is still little known and very few data are available in literature.We describe a case of a 31-year-old male cocaine user admitted to our department for typical acute chest pain.Coronary angiography showed diffuse coronary ectasia with slow flows and without hemodynamically significant stenosis.An increasing of matrix metalloproteinases values and a reduction of their tissue inhibitors was showed both during hospitalization and at one month after discharge.This case report emphasizes the close relationship between cocaine abuse,CAE and acute coronary syndromes in patients without hemodynamically significant coronary stenosis.As reported by Satran et al,cocaine abuse should be considered an important risk factor for CAE and these patients appear to be at increased risk of angina and acute myocardial infarct.Further studies that can strengthen this hypothesis would be useful to deepen and better analyze this interesting association.

    Mesenteric traction syndrome (MTS) consists of decreased systemic vascular resistance, increased cardiac output, facial flushing and palmar erythema. Local production of PGI2 is thought to be the cause. We experienced a rare case of MTS that occurred during coronary artery bypass graft surgery (CABG). A 64-year-old man was scheduled for CABG for the treatment of angina pectoris. Hemodynamic variables were stable until 50 minutes after surgical incision. Blood pressure fell down suddenly from 110/50 to 70/40 mmHg, accompanied by obvious facial flushing and palmar erythema, when the surgeons were preparing the right gastroepiploic artery. Hemodynamic changes and cutaneous hyperemia returned to the baseline level in about 40 minutes. After this episode, the operation was performed uneventfully. The time sequence between the onset of the surgical procedure and the hemodynamic and cutaneous findings strongly suggest the release of PGI2 and MTS. In patients undergoing CABG with the gastroepiploic artery graft, pretreatment with NSAID might avoid sudden circulatory changes of MTS.

    Ischemic heart disease is the leading cause of mortality worldwide. Due to advances in medicine in the past few decades, life expectancy has increased resulting in an aging population in developed and developing countries. Acute coronary syndrome causes greater morbidity and mortality in this group of older patients, which appears to be due to age-related comorbidities. This review examines the incidence and prevalence of acute coronary syndrome among older patients, examines current treatment strategies, and evaluates the predictors of adverse outcomes. In particular, the impact of frailty on outcomes and the need for frailty assessment in developing future research and management strategies among older patients are discussed.

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

    Previously we discovered that routine periodic fasting was associated with a lower prevalence of coronary artery disease (CAD). Other studies have shown that fasting increases longevity in animals. A hypothesis-generating analysis suggested that fasting may also associate with diabetes. This study prospectively tested whether routine periodic fasting is associated with diabetes mellitus (DM). Patients (n = 200) undergoing coronary angiography were surveyed for routine fasting behavior before their procedure. DM diagnosis was based on physician reports of current and historical clinical and medication data. Secondary end points included CAD (physician reported for ≥ 1 lesion of ≥ 70% stenosis), glucose, and body mass index (BMI). Meta-analyses were performed by evaluation of these patients and 448 patients from a previous study. DM was present in 10.3% of patients who fasted routinely and 22.0% of those who do not fast (odds ratio [OR] 0.41, 95% confidence interval [CI] 0.17 to 0.99, p = 0.042). CAD was found in 63.2% of fasting and 75.0% of nonfasting patients (OR 0.42, CI 0.21 to 0.84, p = 0.014), and in nondiabetics this CAD association was similar (OR 0.38, CI 0.16 to 0.89, p = 0.025). Meta-analysis showed modest differences for fasters versus nonfasters in glucose concentrations (108 ± 36 vs 115 ± 46 mg/dl, p = 0.047) and BMI (27.9 ± 5.3 vs 29.0 ± 5.8 kg/m(2), p = 0.044). In conclusion, prospective hypothesis testing showed that routine periodic fasting was associated with a lower prevalence of DM in patients undergoing coronary angiography. A reported fasting association with a lower CAD risk was also validated and fasting associations with lower glucose and BMI were found. Copyright © 2012 Elsevier Inc. All rights reserved.

    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.

    Myocardial imaging using technetium 99m stannous pyrophosphate (/sup 99m/Tc-PYP) has been utilized preoperatively and three to five days postoperatively to detect myocardial infarction in 48 patients undergoing aortocoronary bypass grafting, including 7 having valve replacement (5 aortic, 2 mitral) in addition to revascularization. In the total group of patients operated on there were 3 deaths (6%). Preoperatively, 26 patients had unstable angina and 10 had severe left main coronary artery disease. Eleven of the 48 (23%) were women. ECG and enzyme-proved infarctions occurred in 6 of the 48 patients (12%), but the addition of /sup 99m/Tc-PYP myocardial imaging demonstrated scintigraphic evidence of infarction in 15 patients (31%), including 2 who died in the operating room. The /sup 99m/Tc-PYP myocardial imaging technique, which has proved safe, simple, and relatively inexpensive in these patients, suggests that the incidence of infarction after coronary bypass operations is somewhat higher than has been previously recognized from just ECG and enzyme changes. This technique also has been of value in helping to exclude myocardial infarction in difficult clinical situations such as postoperative arrhythmias and the postpericardiotomy syndrome.

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation. If defibrillation is not available in patients with cardiac arrest due to VTA

    The assessment of the cardiovascular risk profile in patients with end-stage liver disease is essential prior to liver transplantation (LT) as cardiovascular diseases are major causes of morbidity and mortality in the posttransplant course. The aim of this study was to evaluate the accuracy of a 64-slice coronary computed tomographic angiography (CTA) and coronary calcium scoring (CCS) to predict the postoperative cardiovascular risk of patients assessed for LT. In this single center, observational study we included 54 consecutive patients who were assessed for LT and consequently transplanted. Twenty-four patients (44%) presented with a high CCS above 300 and/or a significant stenosis (>50% percent narrowing due to stenotic plaques) and were further referred to coronary angiography. Three of these patients had a more than 70% LAD stenosis with subsequent angioplasty (n = 1) or conservative therapy (n = 2). The other patients showed only diffuse CAD without significant stenosis. The remaining 30 patients with normal CTA findings were listed for LT without further tests. None of the 54 patients developed cardiovascular events peri- and postoperatively. This study indicated that CTA combined with CCS is a useful non-invasive imaging technique for pre-LT assessment of coronary artery disease and safe tool in the risk assessment of peri- and postoperative cardiovascular events in patients undergoing LT.

    Objective To study whether myeloperoxidase (MPO) can provide prognostic information in patients with acute coronary syndromes (ACS). Methods The study population consisted of 274 consecutive patients with ACS. All patients underwent coronary angiography which showed significant coronary artery disease and blood samples were collected at admission. Follow-ups were scheduled at 1, 3, and 6 months.The end point included cardiac death, acute myocardial infarction (MI), percutaneous or surgical revascularization. Results Patients with elevated MPO serum levels (MPO ≥ 72.2 AUU/L) were more likely to have diabetics and had a history of coronary events. Kaplan-Meier event rate curves with accumulative incidence of end point at 6-month follow-up in the MPO ≥ 72.2 AUU/L group was significantly higher than in MPO<72.2 AUU/L group. Conclusions MPO may be a powerful predictor of adverse outcome in patients with ACS.

    Objective: To investigate the relationship of matrix metalloproteinase-9 polymorphism to acute coronary syndrome and its affect on the severity of coronary artery disease. Methods: By means of polymerase chain reaction (PCR) and restriction fragment length polymorphism, genotypes of 245 patients with acute coronary syndrome(ACS) and 205 healthy subjects were tested. Genotypes displaying C-1562T functional promoter polymorphism (of the MMP-9 gene) were determined. The relationship between the polymorphism of the MMP-9 gene and ACS and the severity of coronary vessels diseased was analyzed. Results: The frequency of C/T plus T/T genotypes and T allele in patients with ACS was significantly higher than that in healthy subjects (22.1% vs 12.7% and 11.4% vs 6.6% respectively). But they were not associated with the number of coronary arteries diseased. Conclusion:The MMP-9 polymorphism may be susceptible to ACS. But there was not significant difference between the AMI and UAP subgroups.

    2017-01-01

    Despite a large volume of evidence supporting the use of dual antiplatelet therapy in patients with acute coronary syndrome, there remains major uncertainty regarding the optimal duration of therapy. Clinical trials have varied markedly in the duration of therapy, both across and within trials. Recent systematic reviews and meta-analyses suggest that shorter durations of dual antiplatelet therapy are superior because the avoidance of atherothrombotic events is counterbalanced by the greater risks of excess major bleeding with apparent increases in all-cause mortality with longer durations. These findings did not show significant heterogeneity according to whether patients had stable or unstable coronary heart disease. Moreover, the potential hazards and benefits may differ when applied to the general broad population of patients encountered in everyday clinical practice who have markedly higher bleeding and atherothrombotic event rates. Clinicians lack definitive information regarding the duration of therapy in patients with acute coronary syndrome and risk scores do not appear to be sufficiently robust to address these concerns. We believe that there is a pressing need to undertake a broad inclusive safety trial of shorter durations of therapy in real world populations of patients with acute coronary syndrome. The clinical evidence would further inform future research into strategies for personalised medicine. PMID:28249994

    Full Text Available The number of patients with a previously diagnosed malignancy who need cardiac surgery is increasing. Patients with hematological malignancies represent only 0.38% of all patients undergoing cardiac surgery. The literature in this subset of patients is limited to only a few retrospective case series, with limited number of patients undergoing emergency cardiac surgery. We describe three cases with hematological malignancies namely chronic myelogenous leukemia, acute promyelocytic leukemia and chronic lymphocytic leukemia presenting for coronary artery bypass grafting (CABG. Two patients were taken up for emergency CABG in view of ongoing ischemia, one of them was on preoperative intra-aortic balloon pump support. No mortality was observed. Two patients needed transfusion of blood products which was guided by thromboelastography. One patient developed superficial sternal wound infection requiring antibiotic therapy.

    The 12-lead electrocardiogram(ECG)is a crucial tool in the diagnosis and risk stratification of acute coronary syndrome(ACS).Unlike other 11 leads,lead aVR has been long neglected until recent years.However,recent investigations have shown that an analysis of ST-segment shift in lead aVR provides useful information on the coronary angiographic anatomy and risk stratification in ACS.ST-segment elevation in lead aVR can be caused by(1)transmural ischemia in the basal part of the interventricular septum caused by impaired coronary blood flow of the first major branch originating from the left anterior descending coronary artery;(2)transmural ischemia in the right ventricular outflow tract caused by impaired coronary blood flow of the large conal branch originating from the right coronary artery;and(3)reciprocal changes opposite to ischemic or non-ischemic ST-segment depression in the lateral limb and precordial leads.On the other hand,ST-segment depression in lead aVR can be caused by transmural ischemia in the inferolateral and apical regions.It has been recently shown that an analysis of T wave in lead aVR also provides useful prognostic information in the general population and patients with prior myocardial infarction.Cardiologists should pay more attention to the tracing of lead aVR when interpreting the12-lead ECG in clinical practice.

    Objectives Early and accurate diagnosis of peripheral atherosclerosis is of paramount importance for global managerment of patients with known coronary artery disease (CAD), especially in the elderly. We sought to evaluate the prevalence and clinical relevance of significant abdominal vessel stenosis or aneurysm (AVA) in patients undergoing coronary angiography. Methods Medical records of consecutive > 75-year old patients who underwent coronary angiography at two public institutions over a 12-month period were evaluated. Angiographic results of patients who underwent coincident diagnostic abdominal aorta angiography to evaluate abdominal vessels on the basis of clinical and angiographic criteria were analyzed. Results During the study period, AVA was found in 90 (35.7% ) of 252 consecutive patients (185 males, mean age 79±5.8 years), renal artery stenosis in 13.1% of cases (33 patients), aortoiliac artery disease in 13.7 % (35 patients), and aortic aneurismal disease in 8.9% (22 patients). Logistic regression analyses revealed > 3-vessel CAD (odds ratio [OR] :9.917, P = 0.002), and > 3 risk factors (OR: 2.8, P =0. 048) as independent predictors of AVA. Conclusions Aged patients with multivessel CAD frequently have a high risk profile and multiple vascular atherosclerotic distributions, suggesting the usefulness of a mere global and comprehensive cardiovascular approach in aged patients.

    Full Text Available ABSTRACT Objective: to investigate the factors associated with mortality in patients undergoing coronary artery bypass grafting in a cardiovascular referral hospital in Santa Catarina. Method: quantitative, exploratory, descriptive and retrospective study. The medical records of 1447 patients, from 2005 to 2013, were analyzed for statistically related variables, these being: profile, hospitalization diagnosis, risk factors for coronary artery disease, complications recorded during the hospitalization, length of hospitalization and cause of death. Results: the mortality rate was 5.3% during the study period. Death was more common in females and those of black skin color, with a mean age of 65 years. Acute myocardial infarction was the most common hospitalization diagnosis. The majority of the complications recorded during hospitalization were characterized by changes in the cardiovascular system, with longer hospitalization periods being directly related to death from septic shock. Conclusion: the data provide subsidies for nursing work with preventive measures and early detection of complications associated with coronary artery bypass grafting. This reinforces the importance of using the data as quality indicators, aiming to guarantee care guided by reliable information to guide managers in planning patient care and high complexity health services.

    We designed a prospective observational study targeting a selective population of patients undergoing elective coronary artery bypass grafting with normal systolic function. In this study we looked at the prevalence of pre-operative microvolt T-wave alternans and if it predicts atrial fibrillation after surgery. The inclusion criteria included all patients referred to the cardiothoracic outpatient clinic for elective bypass, who can perform aerobic exercise, with a recent exercise stress test exercising at least to 85% of the maximal predicted heart rate (220 - age) and with non-limiting chest pain at maximal exercise. Twenty patients met the inclusion/exclusion criteria between May 2008 and February 2010. The hospital course of those patients was followed, and in-hospital events were recorded. Nine out twenty (45%) of patients had a non-negative microvolt T-wave alternans tracing. Six patients (30%) developed new onset atrial fibrillation post surgery. Patients with non-negative microvolt level T-wave alternans are more likely to develop atrial fibrillation post coronary artery bypass grafting then patients with negative microvolt level T-wave alternans (p=0.05). This pilot study provides the first clinical evidence that patients with ischemic heart disease and normal systolic function have a high prevalence of abnormal microvolt T-wave alternans and might be at higher risk of sudden cardiac death. In addition our results show that microvolt level T-wave alternans predicts post coronary artery bypass grafting new onset atrial fibrillation.

    OBJECTIVE: To study a strategy of aggressive coronary balloon angioplasty with provisional stenting in allcomers. In randomized trials, stenting has improved the outcome of patients undergoing coronary intervention. However, whether these results hold up in clinical practice is largely unknown. Furthermore, the results of balloon angioplasty have also improved dramatically. It is therefore essential to evaluate the current results of balloon angioplasty and to assess whether stents are required in all patients. METHODS: The authors prospectively studied the occurrence of death, myocardial infarction (MI) and target lesion revascularization (TLR) of a large consecutive group of patients undergoing aggressive balloon angioplasty with provisional stenting. None of the patients received a platelet glycoprotein IIb/IIIa receptor blocker. The results were compared with the outcome of routine stenting in recent randomized trials. RESULTS: Angioplasty was performed in 1058 patients of whom 369 (34.9%) received a stent. The angiographic success rate was 98.9%. During hospital stay, 4.8% of the patients suffered any cardiac event. At one-year follow-up, death occurred in 1.1%, MI in 3.3%, TLR in 12.4% and any event in 16.7% of the patients. Event-free survival at one-year was 82.3%. These results compare favorably with routine stenting in recent trials. CONCLUSIONS: Aggressive balloon angioplasty with provisional stenting yields excellent results in a general patient population.

    Full Text Available We present a case of stress-induced myocardial stunning, also known as tako-Tsubo syndrome, in an anaesthetised patient undergoing arthroscopic replacement of the cruciate ligament. The patient′s (44 y male, ASA class II had a history of hypertension with no other known disease. He underwent a femoral nerve block with 20 ml of 0.5% ropivacaine before receiving a balanced general anaesthesia (propofol induction, sevoflurane maintenance, 10 µg/kg sufentanil. Ten min after the beginning of surgery during endoscopic intra-articular manipulation, the patient suffered from bradycardia and hypotension; following the administration of ephedrine and atropine, he developed tachycardia, hypertension and ST segment depression. Subsequently, his systemic blood pressure dropped necessitating inotropic drug support and - later - intraaortic balloon counterpulsation; a TEE revealed no evidence of hypovolemia, anterior and antero-septal hypokinesia with an ejection fraction of 25%. Surgery was finished whilst stabilising the patient haemodynamically. Postoperative cardiac enzymes showed little elevation, an emergency coronary angiogram apical akinesia with typical ballooning and basal hyperkinesias, compatible with Tako-tsubo syndrome. The patient′s postoperative course was uneventful. We theorize that stress caused by sudden surgical pain stimulus (introduction of the endoscope into the articulation, superficial anaesthesia and insufficient analgesia created a stressful event which probably might have caused a catecholamine surge as basis of Tako-tsubo syndrome.

    Full Text Available Background: During off-pump coronary artery bypass (OPCAB, the heart is subjected to ischemic and reperfusion injury. Preconditioning is a mechanism that permits the heart to tolerate myocardial ischemia. The aim of this study was to compare the effects of Adenosine preconditioning with ischemic preconditioning on the global ejection fraction (EF in patients undergoing OPCAB.Methods: In this single-blind, randomized controlled trial, sixty patients undergoing OPCAB were allocated into three equally-numbered groups through simple randomization: Adenosine group, ischemic group, and control group. The patients in the Adenosine group received an infusion of Adenosine. In the ischemic group, ischemic preconditioning was induced by the temporary occlusion of the left anterior descending coronary artery twice for a 2-minute period, followed by 3-minute reperfusion before bypass grafting of the first coronary vessel. The control group received an intravenous infusion of 0.9% saline. Blood samples at different times were sent for the measurement of creatine kinase isoenzyme MB (CK-MB and cardiac troponin I (cTnI. We also recorded electrocardiographic indices and clinical parameters, including postoperative use of inotropic drugs and preoperative and postoperative EF.Results: History of myocardial infarction, hyperlipidemia, diabetes mellitus, kidney disease, preoperative arrhythmias, and utilization of postoperative inotrope was the same between the three groups. The incidence of postoperative arrhythmias was not significant between the three groups. Also, there were no significant differences in preoperative and postoperative EF and the serum levels of enzymes (cTnI and CK-MB between the groups.Conclusion: Based on the findings of this study, there was no significant difference in the postoperative EF between the groups. Although the incidence of arrhythmias was higher in the ischemic preconditioning group than in the other groups, the difference

    Full Text Available A number of "interesting" risk markers have been proposed as providing prognostic information in acute coronary syndromes (ACS. Elevation in plasma inflammatory and necrosis biomarkers have been related to future cardiovascular events in individuals with or without prior myocardial infarction. Recently BNP and pro-BNP are entered in clinical practice to recognize patients at major risk, providing incremental information respect to the traditional markers. Together with these laboratory indexes, a few of promising laboratory markers once easily available, could become useful in identification of patients at high risk. Several studies evaluated many markers of platelet aggregation, endothelial dysfunction and vascular thrombosis, but it is not yet clear whether each of the proposed markers may provide incremental predictive information. We describe, following the most studies reported in literature, the laboratory markers with potential clinical and prognostic power that could early help physicians in the identifi cation of patients with impaired coronary disease and more narrowed coronary arteries.

    Full Text Available Metabolic Syndrome (MS or insulin resistance syndrome is commonly defined as a group of risk factors or abnormalities associated with insulin resistance that markedly increased risk for both coronary heart disease and diabetes. Cardiovascular disease and all-cause mortality, even in the absence of baseline CVD and diabetes. Early identification, treatment and prevention of the metabolic syndrome present a major challenge for health care professionals facing an epidemic of overweight and sedentary lifestyle. AIMS AND OBJECTIVES To study the prevalence of metabolic syndrome in pts. with Acute Coronary Syndrome (ACS and its effect on hospital outcomes. MATERIALS AND METHODS Observational study in 55 cases (28 cases and 27 controls was conducted in Dr. BRAMH, Raipur and each patient was assessed with detailed clinical history and was also assessed for parameters of MS. The cases and controls were also followed up during their hospital stay for the presence of or development of heart failure, arrhythmias, shock and death. Chi square and ‘t’ test were used to analyse obtained data. RESULTS AND CONCLUSIONS In the present study sex ratio amongst the cases was (M:F 1.15:1 and 2.6:1 in controls. Maximum patients were between the ages of 50-60. Non-ST elevation MI was more common in patients with metabolic syndrome and they presented late to the hospital for treatment. Hypertension and fasting hyperglycemia are the most prevalent components of metabolic syndrome in patients of acute coronary syndrome. Our Study also suggests that hypertriglyceridemia is the most common lipid abnormality in patients of acute coronary syndrome. An increase in the incidence of heart failure was observed in patients with metabolic syndrome Cardiogenic shock is seen with increased frequency in patients with metabolic syndrome. Case fatalities were seen with equal frequency in both the groups, hence metabolic syndrome is not associated with increased case fatality while

    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). After the adjustment for all potential

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

    Full Text Available Background: Elevated mean platelet volume (MPV has been proposed as a risk factor for coronary artery disease (CAD and is associated with poor clinical outcome in acute coronary syndrome (ACS. However, some studies have contradictory findings. Hence, we aimed to evaluate the association of MPV with the presence of coronary collateral vessel (CCV in patients with ACS. Objective: To find MPV value in ACS patients and to find the predictive value of MPV in the spectrum of CAD and to examine whether levels of MPV predict the presence of CCVs. Methods: A total of 180 patients with first ACS were included in the study. MPV was measured. All patients underwent coronary angiography to know disease severity and CCVs. The CCVs are graded according to the Rentrop scoring system and according to coronary angiography results; patients were divided into two groups as Group 1 (poor CCV and Group 2 (good CCV. Results: The MPV was 10.74 ± 2 fl in poor collateral group patients and 11.01 ± 1.7 fl in good collateral group (P = 0.421. The presence of CCV was not significantly associated with high levels of MPV. MPV value did not show any prediction of the spectrum of CAD. Conclusion: MPV on admission was not associated with the development of CCV positively in patients with ACS. Furthermore, it is not associated with a number of vessel involvements.

    Sleep apnoea hypopnoea syndrome (SAHS) is characterised by repetitive nocturnal hypoxemia and has a high prevalence among patients with acute myocardial infarction (AMI). But there are few studies on patients with AMI undergoing emergency primary percutaneous coronary intervention (pPCI). In this study, we want to find the prevalence of SAHS among patients with AMI undergoing emergency pPCI and determine whether SAHS would worsen the condition among these people, and especially affect the damage degree of the coronary artery. Over four months, 95 patients admitted for the first time for AMI were observed. All of them had emergency primary PCIs. A total of 86 patients accepted the sleep study and were divided into four groups according to the apnoea hypopnoea index (AHI): SAHS was diagnosed when AHI ≥5/h and was defined as mild for AHI ≥5/h and emergency pPCI. There were significant differences in average ages, smoking and arrhythmia (Pemergency pPCI, there is a high prevalence of SAHS. There are also positive correlations between AHI and Gensini score, and pro-BNP. Therefore, guided by the results, should we conduct a routine screening to those patients normally and could we relieve the damage to the coronary artery by curing the SAHS?

    A large proportion of patients with coronary disease have metabolic syndrome, although the frequency and association of its different components are not well understood. The aim of this study was to determine the prevalence of metabolic syndrome and the combination of its components in a Spanish cohort of patients with acute coronary syndrome. Clinical histories of 574 inpatients with acute coronary syndrome in 6 tertiary hospitals were reviewed and the presence of metabolic syndrome and its components determined by applying Adult Treatment Panel III criteria. In a second step, the components of the metabolic syndrome were analyzed, excluding those patients with diabetes mellitus. The metabolic syndrome was present in 50.9% of patients and was more frequent in women than in men (66.3% vs. 47.3%; P<.001). The most prevalent component was carbohydrate metabolism disorder (85.3%), followed by low high-density lipoprotein cholesterol (HDLc) levels (80.5%). In nondiabetic patients, 34.6% had metabolic syndrome and the most prevalent component was low HDLc levels (86%), followed by high blood pressure and hypertriglyceridemia and, in fourth place, impaired fasting serum glucose levels. The metabolic syndrome has a high prevalence in patients with an acute coronary syndrome, especially in women. The most frequent components are hyperglycemia and low HDLc levels. After excluding diabetic patients, the most prevalent diagnostic criterion of metabolic syndrome was low HDLc levels. Full English text available from: www.revespcardiol.org.

    Objective To explore the effects of platelet membrane glycoprotein GPllb/llla receptor antagonists tirofiban on myocardium ischemia-reperfusion and left ventricular function of patients with acute coronary syndromes( ACS) undergoing delayed percutaneous coronary intervention( delayed PCI) ,and to find out whether early administration of tirofiban in patients with ACS can improve myocardium ischemia – reperfusion before and after delayed PCI and left ventricular function at late stage and the prognosis of ACS. Methods 150 non-emergency hospitalized patients with ACS treated in our department of cardiology were selected and sim-ply randomized into observation group(tirofiban plus routine therapy,n=75)and control group(routine therapy only,n=75). All pa-tients were given coronary artery angiograph and PCI after one week. The degree of TIMI flow,corrected TIMI frame count( CTFC) af-ter PCI,left ventricular function indexes( NT pro BNP,LVEF,LVEDD,LVESD) and the incidence of bleeding complications examined before and 1,3,6,and 12 months after delayed PCI were compared and analyzed. Results The difference in the degree of TIMI flow of infarct-related artery(IRA)between two groups was not statistically significant(P>0. 05). CTFC of IRA after delayed PCI in the tirofiban therapy group was significantly lower than that in control group(P0. 05). Left ventricular function indexes in the tirofiban therapy group were significantly better than those in the control group 3 and 6 months after delayed PCI(P0. 05). Conclusions Early administration of tirofiban in patients with ACS undergoing delayed PCI improves myocardial reper-fusion and the prognosis of left ventricular function,without significant increase of the incidence of bleeding complications. Thus it helps patients with ACS who missed emergency revascularization to find a new treatment to improve the prognosis and provides refer-ence for clinical application.%目的:探讨早期应用血小板膜糖蛋白( GP)Ⅱb/

    Drug-induced type I hypersensitivity reactions are frequent. Sometimes, acute coronary syndrome (ACS) can be registered in such patients, which may have a serious impact on the course and management of the allergic reaction. Because of potentially atypical ACS clinical presentations, the ECG is an obligatory diagnostic tool in any allergic reaction. Coronary artery spasm is the pathophysiological basis of ACS, triggered by the action of potent vasoactive mediators (histamine, neutral protease...

    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.

    Full Text Available Asli Tanindi, Mustafa CemriGazi University Faculty of Medicine, Department of Cardiology, Ankara, TurkeyAbstract: Acute coronary syndromes comprise a large spectrum of clinical conditions ranging from unstable angina pectoris to acute ST-elevation myocardial infarction. Chest pain is usually the major symptom of atherosclerotic heart disease; however, it may be challenging to diagnose correctly, especially in the emergency department, because of the ambiguous way that pain is characterized by some patients. Cardiac troponins are sensitive and specific biomarkers used in the diagnosis of myocardial infarction that are released into the bloodstream when cardiac myocytes are damaged by acute ischemia or any other mechanism. They are the cornerstone for the diagnosis, risk assessment, prognosis, and determination of antithrombotic and revascularization strategies. However, troponin elevation indicates the presence, not the mechanism, of myocardial injury. There are many clinical conditions other than myocardial infarction that cause troponin elevation; thus, the physician should be aware of the wide spectrum of disease states that may result in troponin elevation and have a clear understanding of the related pathophysiology to effectively make a differential diagnosis. This review focuses on causes of troponin elevation other than acute coronary syndromes.Keywords: cardiac troponin, troponin elevation without acute coronary syndrome, differential diagnosis

    SYNTAX score is an angiographic scoring system that was developed to quantify the number, complexity, and location of lesions in patients undergoing coronary revascularization. Up to now, the impact of SYNTAX score on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) for unprotected left main coronary artery (LMCA) lesions has not been fully examined. Therefore, we evaluate the usefulness of the SYNTAX score and identify the cutoff value of this score to predict 1-year clinical outcomes in patients undergoing PCI for unprotected LMCA lesions. This was a single-center retrospective study that included 49 consecutive patients undergoing elective PCI for unprotected LMCA lesions. We calculated the SYNTAX score and examined the correlations between this score and 1-year clinical outcomes. Major adverse cardiac events (MACE) occurred in 12 patients (24%): target lesion revascularization in 9 patients (18%), myocardial infarction in 2 (4%), and cardiac death in 1 (2%). The frequency of MACE was significantly higher in the intermediate (47%) or high score group (50%) than in the low score group (4%). Furthermore, the SYNTAX score was significantly higher in the MACE group than in the non-MACE group (31 vs. 22, p = 0.008). Receiver-operating characteristic curve showed that the SYNTAX score exhibited 83% sensitivity and 76% specificity for predicting the development of MACE at a cutoff value 26. These results demonstrate that the SYNTAX score could be a useful tool to predict 1-year clinical outcomes in patients undergoing elective PCI for unprotected LMCA lesions.

    Full Text Available Selecting an ideal antithrombotic therapy for elderly patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI can be challenging since they have a higher thromboembolic and bleeding risk than younger patients. The current study aimed to assess the efficacy and safety of triple therapy (TT: oral anticoagulation plus dual antiplatelet therapy: aspirin plus clopidogrel in patients ≥75 years of age with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI.A prospective multicenter study was conducted from 2003 to 2012 at 6 Spanish teaching hospitals. A cohort study of consecutive patients with AF undergoing PCI and treated with TT or dual antiplatelet therapy (DAPT was analyzed. All outcomes were evaluated at 1-year of follow-up.Five hundred and eighty-five patients, 289 (49% of whom were ≥75 years of age (79.6±3.4 years; 33% women were identified. TT was prescribed in 55.9% of patients at discharge who had a higher thromboembolic risk (CHA2DS2VASc score: 4.23±1.51 vs 3.76±1.40, p = 0.007 and a higher bleeding risk (HAS-BLED ≥3: 88.6% vs 79.2%, p = 0.02 than those on DAPT. Therefore, patients on TT had a lower rate of thromboembolism than those on DAPT (0.6% vs 6.9%, p = 0.004; HR 0.08, 95% CI: 0.01-0.70, p = 0.004. Major bleeding events occurred more frequently in patients on TT than in those on DAPT (11.7% vs 2.4%, p = 0.002; HR 5.2, 95% CI: 1.53-17.57, p = 0.008. The overall mortality rate was similar in both treatment groups (11.9% vs 13.9%, p = 0.38; however, after adjustment for confounding variables, TT was associated with a reduced mortality rate (HR 0.33, 95% CI: 0.12-0.86, p = 0.02.In elderly patients with AF undergoing PCI, the use of TT compared to DAPT was associated with reduced thromboembolism and mortality rates, although a higher rate of major bleeding.

    Identification of individuals who are at risk of suffering from acute coronary syndromes (ACS) may allow to introduce preventative measures. We aimed to identify ACS-related urinary peptides, that combined as a pattern can be used as prognostic biomarker. Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases). Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75). ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664), which was similar to Framingham risk scoring (c-statistics = 0.644) in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP), combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751) resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001) and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007). In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice. PMID:28273075

    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.

    Objective: To determine whether polymorphisms in the genes for coagulation factor II,V, VII could predispose an individual to increase risk for coronary artery disease (CAD) and/or myocardial infarction (MI) in Chinese. Methods: We screened coagulation factor II(G20210A),V(G1691A),VII (R353Q and HVR4) genotype in 374 patients undergoing coronary angiography by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) assay. Results: The R353Q and HVR4 genotype of the factor VII distribution was in accordance with Hardy-Weinberg equilibrium. The frequencies of FVII genotype or allele did not show statistically significant differences between CAD group and controls or between male and female. The frequencies of the Q allele and (RQ+QQ) genotype were significantly higher among the CAD patients without myocardial infarction (MI) history than among those with MI history (P<0.05). However, HVR4 polymorphism was not significantly different within groups. We only find one normal control of factorII(G20210A) mutation. No coagulation factor V(G1691A) mutation was found in the CAD patients and controls. Conclusion: The factor II(G20210A),V(G1691A) mutation is absent and may not be a major genetic factor for CAD and/or MI; the Q allele of the R353Q polymorphism of the factor VII gene may be a protective genetic factor against myocardial infarction in Chinese.

    Objective: To determine whether polymorphisms in the genes for coagulation factor Ⅱ,Ⅴ,Ⅶ could predispose an individual to increase risk for coronary artery disease (CAD) and/or myocardial infarction (MI) in Chinese. Methods: We screened coagulation factor Ⅱ( G20210A),Ⅴ( G1691A),Ⅶ( R353Q and HVR4) genotype in 374 patients undergoing coronary angiography by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) assay. Results: The R353Q and HVR4 genotype of the factor Ⅶ distribution was in accordance with Hardy-Weinberg equilibrium. The frequencies of FVⅡ genotype or allele did not show statistically significant differences between CAD group and controls or between male and female.The frequencies of the Q allele and ( RQ + QQ) genotype were significantly higher among the CAD patients without myocardial infarction (MI) history than among those with MI history (P < 0.05). However, HVR4 polymorphism was not significantly different within groups. We only find one normal control of factorⅡ(G20210A) mutation. No coagulation factor Ⅴ(G1691A) mutation was found in the CAD patients and con-trois. Conclusion: The factor Ⅱ(G20210A),Ⅴ(G1691A) mutation is absent and may not be a major genetic factor for CAD and/or MI; the Q allele of the R353Q polymorphism of the factor Ⅶ gene may be a protective genetic factor against myocardial infarction in Chinese.

    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.

    Increased platelet activity is associated with adverse cardiovascular events. The mean platelet volume (MPV) correlates with platelet activity; however, the relation between the MPV and long-term mortality in patients undergoing percutaneous coronary intervention (PCI) is not well established. Furthermore, the role of change in the MPV over time has not been previously evaluated. We evaluated the MPV at baseline, 30 days, 60 days, 90 days, 1 year, 2 years, and 3 years after the procedure in 1,512 patients who underwent PCI. The speed of change in the MPV was estimated using the slope of linear regression. Mortality was determined by query of the Social Security Death Index. During a median of 8.7 years, mortality was 49.3% after PCI. No significant difference was seen in mortality when stratified by MPV quartile (first quartile, 50.1%; second quartile, 47.7%; third quartile, 51.3%; fourth quartile, 48.3%; p = 0.74). For the 839 patients with available data to determine a change in the MPV over time after PCI, mortality was 49.1% and was significantly greater in patients with an increase (52.9%) than in those with a decrease (44.2%) or no change (49.1%) in the MPV over time (p <0.0001). In conclusion, no association was found between the baseline MPV and long-term mortality in patients undergoing PCI. However, increased mortality was found when the MPV increased over time after PCI. Monitoring the MPV after coronary revascularization might play a role in risk stratification.

    Abstract Pheochromocytomas are neuroendocrine tumors, and its cardiac involvement may include transient myocardial dysfunction, acute coronary syndrome (ACS), and even ventricular arrhythmias. A patient was referred for evaluation of stuttering chest pain, and his electrocardiogram showed T-wave inversion over leads V1 to V4. Coronary angiography showed 90% stenosis in the mid-left anterior descending coronary artery (LAD), which was stented. Five days later, the patient had ventricular tachycardia, and severe hypertension, remarkable blood pressure fluctuation between 224/76 and 70/50 mm Hg. The patient felt abdominal pain and his abdominal ultrasound showed suspicious right adrenal gland tumor. Enhanced computed tomography of adrenal gland conformed that there was a tumor in right adrenal gland accompanied by an upset level of aldosterone. The tumor was removed by laparoscope, and the pathological examination showed pheochromocytoma. After the surgery, the blood pressure turned normal gradually. There was no T-wave inversion in lead V1-V4. Our case illustrates a rare pheochromocytoma presentation with a VT and resembling ACS. In our case, the serious stenosis in the mid of LAD could be explained by worsen the clinical course of myocardial ischemia or severe coronary vasospasm by the excessive amounts of catecholamines released from the tumor. Coronary vasospasm was possible because he had no classic coronary risk factors (e.g. family history and smoking habit, essential hypertension, hyperglycemia and abnormal serum lipoprotein, high body mass index). Thus, pheochromocytoma was missed until he revealed the association of his symptoms with abdominalgia. As phaeochromocytomas that present with cardiovascular complications can be fatal, it is necessary to screen for the disease when patients present with symptoms indicating catecholamine excess.

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

    The feasibility and safety of transradial coronary intervention was demonstrated soon after the description of the transfemoral approach, despite which the use of the femoral artery still dominates in acute coronary syndrome intervention. The advantages of using the radial artery are virtual elimination of access site complications and an important reduction in bleeding, both of which are of utmost importance to the patient with myocardial infarction. Randomised controlled trials have now documented what seems inherent; that transradial intervention should bring with it an advantage in terms of morbidity and mortality in this cohort. The potential disadvantages in terms of speed of procedure and radiation exposure are negated by operator experience. Registries have illustrated that conversion on a large scale from the femoral to the transradial approach is safe and saves lives, most convincingly so in acute coronary syndrome intervention. This review discusses the potential benefits and risks of the alternative access sites in acute patients and explores how these are borne out in the published data.

    Ivabradine is a heart rate reducing agent that exhibits anti-ischemic effects through the inhibition of funny electrical current in the sinus node resulting in heart rate reduction, thus enabling longer diastolic perfusion time, and reduced myocardial oxygen consumption without detrimental changes in arterial blood pressure, coronary vasomotion, and ventricular contractility. The current guideline-based clinical use of Ivabradine is reserved for patients with stable angina pectoris who cannot tolerate or whose symptoms are inadequately controlled with beta blockers. In patients with chronic heart failure and reduced ejection fraction, Ivabradine has demonstrated beneficial effects in improving clinical outcomes when added to conventional therapy. However, the role of Ivabradine in acute coronary syndromes has not been established. Based on the results from some relevant preclinical studies and a limited amount of clinical data that were reported recently, the role of Ivabradine in acute ischemic events warrants further investigation. The aim of this review is to provide an overview of the available literature on the potential role of Ivabradine in the clinical context of acute coronary syndromes.

    Restless legs syndrome (RLS) is a common sleep disorder in which patients feel unpleasent leg sensations and urge to move the legs during rest, especially at night, and symptoms are improved by leg movement. Prior studies analyzing the associations between cardiovascular disease and restless legs syndrome has shown controversial results. The goal of the study was to estimate the relationship between restless legs syndrome and slow coronary flow (SCF). The present study was cross-sectional and observational and consists of 176 individuals who underwent coronary angiography and had angiographically normal coronary arteries of varying coronary flow rates. The study included 86 patients with isolated SCF and 90 control participants with normal coronary flow (NCF). RLS was assessed the day after the coronry flow was evaluated, using a self-administered questionnaire based on the International Restless Legs Study Group criteria. The following question was asked: "Do you have unpleasant leg sensations (like crawling, paraesthesia, or pain) combined with motor restlessness and an urge to move?" The possible responses were as follows: no, less than once/month, 2-4 times/month, 5-14 times/month, and 15 or more times per month. Those who answered that they had these feelings were asked the following two more questions: 1) "Do these symptoms occur only at rest and does moving improve them?" and 2) "Are these symptoms worsen in the evening/at night compared with the morning?" RLS is considered to be probable if the participant has answered "yes" for all three of the above questions, and has a frequency of ≥5 times/month. Student's t-test, Mann-Whitney U test, multiple logistic regression analysis were used for statistical analysis. The prevalence of restless legs syndrome was 48 (27%) and increased significantly with age. Patients with SCF have more likely had RLS than the control group (p<0.001). The age-adjusted prevalence odds of SCF were 3.11 times higher (95% CI: 1

    Background Prior studies have demonstrated worse results of women in both hospital and short-term outcomes post-percutaneous coronary intervention. However, with advanced devices like drug-eluting stents (DESs) available,there are no consistent data revealing gender impact in outcome. This study examined whether gender affected hospital outcome and showed one-year single-center patient results of coronary stenting.Methods The study group included 969 consecutive patients (250 women and 719 men) undergoing coronary stenting for stable or unstable angina. Clinical events were assessed for at least 1 year post-procedure.Results Compared to men, women were older, presented more often with diabetes, hypertension, dyslipidemia, and lower creatinine clearance rate (Ccr); they had less percutaneous transluminal coronary angioplasty (PTCA) history,smaller vessel size, and shorter lesions. The hospital major adverse cardiovascular event (MACE) rate was 2.8% of women and 0.97% of men (P=0.037). The one-year MACE rate was 10.0% of women and 10.4% of men (P=0.874). After adjusting other covariates, women still had significantly higher hospital MACE rates (P=0.034) and odds ratios (0.18;95% confidence interval: 0.036-0.874). In women (n=250), there was no statistically significant difference in hospital or one-year MACE between bare metal stent (BMS) and DES groups. Meanwhile, in men (n=719), DES had a significant one-year improvement of MACE compared to BMS (P=0.004). The female hospital MACE rate was five times greater than male results. However, there were similar one-year outcomes between women and men. DES currently have an advantage in long-term outcome.Conclusions Currently, with the use of BMS and DES, adverse hospital post-procedure cardiovascular event rate has occurred more often in women than in men. However, the MACE rate differences between women and men resolved with one year follow-up.

    A 79-year-old woman was out in the garden having lunch on a hot summer day. She developed stabbing chest pains, more severe on her left side, associated with radiation down her left arm. Severity was 7 out of 10. There was no relief of pain with glyceryl trinitrate spray. Risk factors for ischaemic heart disease include hyperlipidaemia, being an ex-smoker (40 years), no history of diabetes or hypertension. There was a family history of her father having a myocardial infarction at the age of 54. Echocardiogram (ECG) revealed widespread deep symmetrical T-wave inversion in the chest leads and lateral limb leads. The patient's serum creatine kinase level was 180 IU/litre (normal range 30-135), troponin I level was 6.56 g/litre (normal range 0-0.10), D-dimer was negative and random serum cholesterol level was 5.3 mmol/litre (3.8-5.2). Significant coronary stenoses were excluded. A left ventriculogram revealed a hyperkinetic base and a dyskinetic apical region of the left ventricle. Echocardiography showed normal valves, basal septal hypertrophy and a dilated akinetic apex, with the region of akinesia spanning more than the arterial territory. Takotsubo cardiomyopathy. Treatment with aspirin, angiotensin-converting enzyme (ACE) inhibitor, β blocker and a statin.

    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.

  19. The "smoker's paradox" in patients with acute coronary syndrome: a systematic review

    Science.gov (United States)

    2011-01-01

    Background Smokers have been shown to have lower mortality after acute coronary syndrome than non-smokers. This has been attributed to the younger age, lower co-morbidity, more aggressive treatment and lower risk profile of the smoker. Some studies, however, have used multivariate analyses to show a residual survival benefit for smokers; that is, the "smoker's paradox". The aim of this study was, therefore, to perform a systematic review of the literature and evidence surrounding the existence of the "smoker's paradox". Methods Relevant studies published by September 2010 were identified through literature searches using EMBASE (from 1980), MEDLINE (from 1963) and the Cochrane Central Register of Controlled Trials, with a combination of text words and subject headings used. English-language original articles were included if they presented data on hospitalised patients with defined acute coronary syndrome, reported at least in-hospital mortality, had a clear definition of smoking status (including ex-smokers), presented crude and adjusted mortality data with effect estimates, and had a study sample of > 100 smokers and > 100 non-smokers. Two investigators independently reviewed all titles and abstracts in order to identify potentially relevant articles, with any discrepancies resolved by repeated review and discussion. Results A total of 978 citations were identified, with 18 citations from 17 studies included thereafter. Six studies (one observational study, three registries and two randomised controlled trials on thrombolytic treatment) observed a "smoker's paradox". Between the 1980s and 1990s these studies enrolled patients with acute myocardial infarction (AMI) according to criteria similar to the World Health Organisation criteria from 1979. Among the remaining 11 studies not supporting the existence of the paradox, five studies represented patients undergoing contemporary management. Conclusion The "smoker's paradox" was observed in some studies of AMI

    This report describes a case of an unusual association between vasospastic angina, coronary myocardial bridging, and Brugada syndrome. The patient complained of chest pain followed by rhythmic palpitation and syncope. Brugada syndrome ECG markers were documented with transient ST-segment elevation in lateral leads. A coronary angiogram showed a myocardial bridging in the left anterior descending artery and coronary vasospasm was reproduced after intracoronary ergonovine injection in the circumflex coronary artery. Ventricular fibrillation was induced by programmed electrical stimulation. The described association can be important because interaction between ischemia and Brugada syndrome electrophysiological substrate could modulate individual susceptibility to life-threatening ventricular tachyarrhythmias.

    The purpose of the study was to compare the EASI system with the standard 12-lead surface electrocardiogram (ECG) for the accuracy in detecting the main electrocardiographic parameters (J point, PR, QT, and QRS) commonly monitored in patients with acute coronary syndromes or heart failure. In this observational comparative study, 253 patients who were consecutively admitted to the coronary care unit with acute coronary syndrome or heart failure were evaluated. In all patients, two complete 12-lead ECGs were acquired simultaneously. A total of 6,072 electrocardiographic leads were compared (3,036 standard and 3,036 EASI). No significant differences were found between the investigate parameters of the two measurement methods, either in patients with acute coronary syndrome or in those with heart failure. This study confirmed the accuracy of the EASI system in monitoring the main ECG parameters in patients admitted to the coronary care unit with acute coronary syndrome or heart failure.

    Introduction A recently published study raised doubts about the need for percutaneous treatment of nonculprit lesions in patients with acute coronary syndromes (ACS). Methods Retrospective, unicentric, observational study. Objective To analyze the long-term outcomes in patients undergoing treatment of the culprit artery, comparing those who remained with significant residual lesions in nonculprit arteries (group I) versus those without residual lesions in other coronary artery beds (group II). The study included 580 patients (284 in group I and 296 in group II) between May 2010 and May 2013. We obtained demographic and clinical data, as well as information regarding the coronary treatment administered to the patients. In the statistical analysis, the primary outcome included combined events (reinfarction/angina, death, heart failure, and need for reintervention). The comparison between groups was performed using the chi-square test and ANOVA. The long-term analysis was conducted with the Kaplan-Meier method, with a mean follow-up of 9.86 months. Results The mean ages were 63 years in group I and 62 years in group II. On long-term follow-up, there was no significant difference in combined events in groups I and II (31.9% versus 35.6%, respectively, p = 0.76). Conclusion The strategy of treating the culprit artery alone seems safe. In this study, no long-term differences in combined endpoints were observed between patients who remained with significant lesions compared with those without other obstructions.

    Kounis syndrome refers to the concurrence of acute coronary events and allergic or hypersensitivity reactions. In this report, we describe the case of a male patient, in whom acute ST-segment elevation and myocardial infarction developed immediately after injection of depot penicillin, and we discuss the Kounis syndrome. A 52-year-old male patient had chest pain, hypotension and ST-elevation on leads DI and aVL of electrocardiography 30 minutes after intramuscular penicillin injection due to cryptic tonsillitis. Kounis syndrome was considered as a possible diagnosis according to the presentation. Histamine and tryptase levels were not studied due to the delay on arrival to the emergency department. The patient promptly underwent coronary angiography, which revealed only diffuse plaques in all main coronary arteries without any obstructive lesion. We found only increased immunoglobulin (Ig) E, which is associated with the syndrome. With this report, we remind clinicians to consider Kounis syndrome in patients who are subjected to allergenic substances and demonstrate acute chest pain.

    Background The high incidence of neuropsychologic deficits after cardiac surgery, including cognitive dysfunction and mood status, has significantly influenced the prognosis, outcome of treatment and long-term quality of life of patients. With a circadian secretion pattern, melatonin and cortisol are capable of modulating the human physiological processes and neuropsychological status, whereas disorder of their secretion pattern may lead to many diseases. However, it is unclear whether neuroendocrine variations are related to the neuropsychologic status in patients undergoing coronary artery bypass grafting (CABG). Methods Forty male patients scheduled for CABG with hypothermic cardiopulmonary bypass (CPB) (n=20) or off-pump coronary artery bypass (OPCAB) (n=20) were studied. Blood samples were taken intraoperatively at specific time-points and every 3 hours within the first postoperative 24 hours to determine plasma concentrations of melatonin and cortisol. A neuropsychologic test battery including depression and anxiety was administered preoperatively and 7 to 10 days postoperatively. Statistical methods included the nonparametric analysis, multiple linear regression and cosinor analysis. Results The patients in the CPB group exhibited more severe neuropsychologic deficits and more anxious than those in the OPCAB group after surgery. In both groups, patients were more depressed postoperatively than preoperatively and recovered 3 months after surgery. Depression and anxiety were correlated with some factors of cognitive dysfunctions. In the postoperative 24 hours, 2 patients in the CPB group, and 6 patients in the OPCAB group showed a circadian rhythm of melatonin secretion. As for cortisol secretion, there were 3 patients in the CPB group and 7 in the OPCAB group respectively. Parameters of circadian rhythm of melatonin in the CPB group and those of secretion rhythm of cortisol in both groups were correlated with depression and some neuropsychologic tests

Objective: To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS as a predictor of cardiovascular complications during hospitalization. Methods: Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1, point of minimum circumference (2; immediately above the iliac crest (3, umbilicus (4, one inch above the umbilicus (5, one centimeter above the umbilicus (6, smallest rib and (7 the point of greatest circumference around the waist (8. Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. Results: A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67% patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. Conclusion: The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Spontaneous platelet aggregation was evaluated in patients with acute coronary syndrome on days 1, 3-5, and 8-12 of the disease. On day 1, aggregation was analyzed after aspirin, but before clopidogrel administration; during other periods after both antiaggregants. The mean levels of spontaneous aggregation after antithrombotic therapy did not change during different periods after the onset of acute coronary syndrome, in contrast to ADP-induced aggregation that decreased after the development of clopidogrel effects (days 3-5 and 8-12). Spontaneous aggregation during different periods directly correlated (r>0.4, p<0.01) with spontaneous and ADP-induced aggregation during different periods (r=0.372, r=0.447, and r=0.543 on days 1, 3-5, and 8-12, respectively; p<0.01). No relationship between spontaneous aggregation and plasma concentration of von Willebrand's factor was detected. Spontaneous aggregation was completely suppressed after in vitro addition of prostaglandin E1 (platelet activation inhibitor), slightly (by ≈20%) decreased in the presence of antibodies to glycoprotein Ib, blocking its reactions with von Willebrand's factor, and did not change in the presence of aptamer inhibiting thrombin activity.

  14. Ticagrelor: A new antiplatelet drug for acute coronary syndromes

    Full Text Available Coronary heart disease and acute coronary syndrome (ACS are a significant cause of morbidity and mortality all over the world. Antiplatelet agents play an essential role in the treatment of acute coronary syndrome (ACS, usually with aspirin and a thienopyridine. Currently, clopidogrel, a second generation thienopyridine, is the main drug of choice, and the combination of aspirin and clopidogrel is administered orally for the treatment of ACS. Clopidogrel, the most commonly used thienopyridine, is limited by a high degree of interpatient variability and inconsistent inhibition of platelets. Ticagrelor, a new, oral, direct-acting P2Y12 receptor antagonist, produces a more profound and consistent antiplatelet effect than clopidogrel. The U.S. Food and Drug Administration approved Ticagrelor on July 20, 2011. Furthermore, ticagrelor has at least one active metabolite, which has pharmacokinetics that are very similar to the parent compound. Therefore, ticagrelor has a more rapid onset and more pronounced platelet inhibition than other antiplatelet agents. The safety and efficacy of ticagrelor compared with clopidogrel, in an ACS patient, has been recently evaluated by the PLATelet inhibition and patient Outcomes (PLATO trial. Clinical studies of patients with both ST-elevation and non-ST-elevation ACS have shown that ticagrelor, when compared with clopidogrel, reduces the rates of vascular death and myocardial infarction. The clinical data currently available indicate that ticagrelor is a promising option for the treatment of patients with ACS and may be of particular use in those at high risk for ischemic events or in those unresponsive to clopidogrel.

    La prévalence des maladies cardiovasculaires connaît une croissance rapide dans les pays en développement, entraînant une incidence croissante du syndrome coronarien aigu (SCA. Les modalités de diagnostic et de traitement de cette maladie continuent d’évoluer, et il convient de tenir compte des ressources locales lors de la réalisation d’un diagnostic et la détermination des options thérapeutiques. Cet article constitue un guide à la prise en charge du SCA fondé sur l’expérience, et fournit des recommandations spécifiques destinées aux médecins hospitaliers travaillant dans les pays à bas et moyen revenu. Le diagnostic du SCA, y compris les SCA sans élévation du ST et avec élévation du ST, se concentre sur la stratification du risque, la vigilance relative aux manifestations subtiles ou atypiques, et la prise en considération d’autres causes des douleurs poitrinaires. Le processus de diagnostic implique l’évaluation des facteurs de risque, la connaissance des antécédents médicaux défavorables et les conclusions de l’examen physique (des variantes étant susceptibles d’exister dans les différentes populations, ainsi que l’utilisation de tests de diagnostic appropriés. Il est recommandé d’utiliser de l’aspirine à titre de traitement initial, parallèlement à un antiagrégant plaquettaire supplémentaire. Le prasugrel est préféré au clopidogrel si le patient présente un SCA avec élévation du ST et qu’une intervention coronaire percutanée (ICP est prévue. La bivalidurine devrait être le premier choix pour éviter la coagulation dans les SCA avec élévation du ST, suivie de l’enoxaparine (qui ne nécessite pas de perfusion, puis d’héparine non fractionnée. Pour les patients présentant un SCA sans élévation du ST et en cas de risque de saignement accru, le fondaparinux devrait être envisagé à la place de l’énoxaparine.

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

    We assessed the influence of insulin resistance (IR) on the development of contrast-induced nephropathy (CIN) in patients (n = 719) undergoing elective percutaneous coronary intervention (PCI). Patients were divided into diabetes mellitus (DM = 242), nondiabetic IR (IR = 120), and nondiabetic insulin sensitivity (IS = 357) groups according to medical history and homeostasis model assessment insulin resistance index. Serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) were measured before and 72 hours after PCI. There were no differences in SCr and eGFR among the groups before PCI; SCr increased and eGFR decreased significantly in the DM and IR groups post-PCI (P < .001). The incidence of CIN in the IR group was as high as in the DM group and were both significantly higher than in the IS group (6.7% vs 8.7% vs 2.2%, P < .05). Multivariate logistic regression analysis showed DM (odds ratio [OR] = 1.19, 95%CI = 1.08-1.510, P < .001), HOMA-IR (OR = 1.39, 95%CI = 1.23-1.58, P < 0.001), and eGFR (OR = 0.88, 95%CI = 0.84-0.92, P < .001) were independent risk factors in predicting CIN. Screening IR patients and taking appropriate prophylactic strategy before PCI may reduce the incidence of CIN.

    The patient undergoing CABG surgery deserves to have confidence that the professional nurse is knowledgeable, caring, efficient, and effective in providing necessary perioperative care. Proper preparation of the patient and significant others, expertise during the intraoperative phase, and a thorough knowledge base combined with skill and compassion of the nursing staff during the postoperative phase increase the likelihood of a positive outcome for the patient. A compassionate, knowledgeable, and skilled nurse caring for the patient after open heart surgery is an asset in the achievement of positive outcomes for the patient and his/her significant others. The care of the CABG patient is intense, complex, and rewarding. The patient is admitted to the intensive care unit unconscious, intubated, and completely dependent on advanced technology as well as the expert care of the health team. Typically 24–48 h after the surgery, the invasive lines have been discontinued, the patient no longer needs to be mechanically ventilated, organ system function is returning to normal, and the patient is now ready to work toward increasing independence. Cardiac surgery is not the cure for coronary artery disease. It gives the patient the opportunity to make needed lifestyle adjustments and achieve the highest degree of health possible. Nurses are a part of the team that makes this return to health a possibility for the patient.

    Full Text Available Abstract Background Type 2 diabetes and the metabolic syndrome are associated with impaired diastolic function and increased heart failure risk. Animal models and autopsy studies of diabetic patients implicate myocardial fibrosis, cardiomyocyte hypertrophy, altered myocardial microvascular structure and advanced glycation end-products (AGEs in the pathogenesis of diabetic cardiomyopathy. We investigated whether type 2 diabetes and the metabolic syndrome are associated with altered myocardial structure, microvasculature, and expression of AGEs and receptor for AGEs (RAGE in men with coronary artery disease. Methods We performed histological analysis of left ventricular biopsies from 13 control, 10 diabetic and 23 metabolic syndrome men undergoing coronary artery bypass graft surgery who did not have heart failure or atrial fibrillation, had not received loop diuretic therapy, and did not have evidence of previous myocardial infarction. Results All three patient groups had similar extent of coronary artery disease and clinical characteristics, apart from differences in metabolic parameters. Diabetic and metabolic syndrome patients had higher pulmonary capillary wedge pressure than controls, and diabetic patients had reduced mitral diastolic peak velocity of the septal mitral annulus (E', consistent with impaired diastolic function. Neither diabetic nor metabolic syndrome patients had increased myocardial interstitial fibrosis (picrosirius red, or increased immunostaining for collagen I and III, the AGE Nε-(carboxymethyllysine, or RAGE. Cardiomyocyte width, capillary length density, diffusion radius, and arteriolar dimensions did not differ between the three patient groups, whereas diabetic and metabolic syndrome patients had reduced perivascular fibrosis. Conclusions Impaired diastolic function of type 2 diabetic and metabolic syndrome patients was not dependent on increased myocardial fibrosis, cardiomyocyte hypertrophy, alteration of the

    Aspirin allergy in a patient with acute coronary syndrome represents one of the more urgent challenges an allergist may face. Adverse reactions to aspirin are reported in 1.5% of patients with coronary artery disease. A history of adverse reaction to aspirin often leads to unnecessary withholding of this medication or use of alternative antiplatelet therapy which may be inferior or more costly. Aspirin therapy has been shown to reduce morbidity and mortality in patients with coronary artery disease. Rapid aspirin challenge/desensitization in the aspirin allergic patient has been consistently shown to be both safe and successful in patients with acute coronary syndromes.

    We present a case of a 34-year-old male who presented to the emergency ward with fever and abdominal pain. The diagnosis of Takayasu's arteritis and also antiphospholipid syndrome was made during an imaging workup of deep-vein thrombosis. A spontaneous coronary artery dissection was revealed in coronary CT angiography requested for chest pain and dyspnea. The patient was treated medically and discharged on close followup. The concurrence of spontaneous coronary artery dissection with antiphospholipid syndrome and Takayasu's arteritis has not been reported in the previous literature. The possibility of a spontaneous coronary artery dissection should be considered in patients presenting with both diseases.

    The management and impact of concomitant coronary artery disease in patients referred for TAVI remains contentious. We describe the prevalence, clinical impact and management of coronary artery disease (CAD) in patients in the United Kingdom TAVI Registry. All-inclusive study of patients undergoing TAVI in the United Kingdom (excluding Northern Ireland) from January 2007 to December 2011. Coronary artery disease at the time of TAVI was demonstrated on invasive angiography. 2588 consecutive patients were entered in the U.K. TAVI Registry. CAD was reported in 1171 pts with left main stem involvement in 12.4% of this cohort (n=145). Most patients were free of chest pain, but limited by dyspnoea (NYHA Class III & IV 81.9%). Angina was however more prevalent in those patients with CAD (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.

    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.

    2016-01-01

    The objective of the current study was to investigate effects of sevoflurane on cardiopulmonary function in patients undergoing coronary artery bypass grafting (CABG). In this study, 60 cases of patients with coronary heart disease (CHD) were selected and randomly divided into the sevoflurane group (group S) and the control group C (group C) with 30 cases in each group. The two groups received intravenous anesthesia. The patients of group C were only given oxygen mask and physiological saline to keep vein open; while the patients of group S were administered with 1% sevoflurane immediately after the beginning of cardiopulmonary bypass (CPB) until the end of the treatment. The cardiopulmonary functions at 30 min before operation (T0), postoperative 2 h (T1), 6h (T2), 24h (T3) and 48 (T4) were observed. The mean arterial pressure (MAP) of the group S at T1, T2, T3 was lower than that of the group C, as were the heart rate (HR) and left ventricular ejection fraction (LVEF). The creatine kinase isoenzyme (CK-MB) during T1 to T4 in the group S was less than that of the group C, and there were significant differences between the two groups (P less than 0.05). The tidal volume (Vt), vital capacity (Vc) and oxygenation index (PaO2/FiO2) of the two groups during T1 and T2 were decreased, while respiratory frequency (RR) and alveolar-arterial blood oxygen partial pressure (PA-aO2) were increased and they began to decrease during T3 and T4. Vt and Vc of the group S were higher during T1 and T2 periods than those of the group C, while RR was lower than that of the group C; PaO2 / FiO2 during T1 to T4 period of group S was higher than that of group C, while PA-aO2 was significantly lower than that of the control group (P less than 0.05). In conclusion, although LVEF was not improved in the sevoflurane group, sevoflurane may contribute to stabilizing the cardiopulmonary function and preventing from myocardial injury.

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in

    Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    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

    Objective This study aimed to analyze the impact of body mass index on outcomes of 101 patients undergoing coronary artery bypass grafting, valve replacement, or combined valve/ coronary artery bypass grafting surgery in a private hospital in Belo Horizonte, Brazil. Methods This was a prospective cross-sectional study of patients undergoing cardiac surgery from May 2009 to December 2012. All patients were followed up from the first day of admission until discharge or death. Patients were divided into three groups according to BMI: normal weight, overweight, and obese. The main outcome measure was the association between BMI and postoperative morbidities and mortality. Results Multivariate analysis identified obesity as an independent predictor of increased risk of surgical reintervention (odds ratio [OR] 13.6; 95%CI 1.1 - 162.9; P=0.046) and reduced risk of bleeding (OR 0.05; 95% CI 0.09 - 0.69; P=0.025). Univariate analysis showed that obesity was associated with increased frequency of wound dehiscence (P=0.021). There was no association between BMI and other complications or mortality in univariate analysis. There was also no association between body mass index and duration of cardiopulmonary bypass, aortic clamping, mechanical ventilation, and intensive care unit or hospital stay. Conclusion Obese individuals undergoing coronary artery bypass grafting, valve replacement, or combined surgery have a higher postoperative risk of surgical reintervention and lower chances of bleeding.

    Aspirin hypersensitivity is not a rare condition among patients with acute coronary syndrome. However, despite the publication of several successful desensitization protocols, the procedure is not as widespread as expected. We present a cohort of patients with acute coronary syndrome undergoing aspirin desensitization to evaluate its short- and long-term efficacy and safety and to reinforce data from previous studies. Of 1306 patients admitted to our Coronary Care Unit between February 2011 and February 2013, 24 (1.8%) had a history of aspirin hypersensitivity. All 24 patients underwent an eight-dose aspirin desensitization protocol (0.1, 0.3, 1, 3, 10, 25, 50 and 100 mg of aspirin given by mouth every 15 minutes) after premedication with antihistamines and corticosteroids or antileucotrienes. Previously prescribed β blockers and angiotensin-converting enzyme inhibitors were not discontinued. All patients were desensitized within 72 hours of admission. Those requiring urgent catheterization (five patients with ST segment elevation myocardial infarction) were desensitized within 12 hours of catheterization and the remainder before catheterization. All patients were successfully desensitized and only one presented with an urticarial reaction. The five patients with ST segment elevation myocardial infarction were treated with abciximab until desensitization was complete. All but one patient underwent catheterization and 20 underwent percutaneous coronary intervention, most (66%) with the implantation of a bare metal stent. At follow-up (a minimum of 6-24 months), only two patients had discontinued aspirin, both due to gastrointestinal bleeding, and no hypersensitivy reaction had occurred. Aspirin desensitization is effective and safe in unstable patients with acute coronary syndrome in both the short and long term.

    Aim: To evaluate the diagnostic accuracy of 16-detector row computed tomography (CT) in assessing haemodynamically significant coronary artery stenoses in patients under evaluation for aortic stenosis pre-aortic valve replacement. Subjects and methods: Forty consecutive patients under evaluation for severe aortic stenosis and listed for cardiac catheterization before potential aortic valve replacement underwent coronary artery calcium (CAC) scoring and retrospective electrocardiogram (ECG)-gated multi-detector row computed tomographic coronary angiography (MDCTA) using a GE Lightspeed 16-detector row CT within 1 month of invasive coronary angiography (ICA) for comparative purposes. All 13 major coronary artery segments of the American Heart Association model were evaluated for the presence of {>=}50% stenosis and compared to the reference standard. Data were analysed on a segment-by-segment basis and also in 'whole patient' terms. Results: A total of 412/450 segments from 35 patients were suitable for analysis. The overall accuracy of MDCTA for detection of segments with {>=}50% stenosis was high, with a sensitivity of 81.3%, specificity 95.0%, positive predictive value (PPV) 57.8%, and negative predictive value (NPV) 98.4%. On a 'whole-patient' basis, 100% (19/19) of patients with significant coronary disease were correctly identified and there were no false-negatives. Excluding patients with CAC >1000 from the analysis improved the accuracy of MDCTA to: sensitivity 90%, specificity 98.1%, PPV 60%, NPV 99.7%. Conclusion: Non-invasive 16-detector row MDCTA accurately excludes significant coronary disease in patients with severe aortic stenosis undergoing evaluation before aortic valve replacement and in whom ICA can therefore be avoided. Its segment-by-segment accuracy is improved further if CAC > 1000 is used as a gatekeeper to MDCTA.

    Apixaban, an oral, direct factor Xa inhibitor, may reduce the risk of recurrent ischemic events when added to antiplatelet therapy after an acute coronary syndrome. We conducted a randomized, double-blind, placebo-controlled clinical trial comparing apixaban, at a dose of 5 mg twice daily, with placebo, in addition to standard antiplatelet therapy, in patients with a recent acute coronary syndrome and at least two additional risk factors for recurrent ischemic events. The trial was terminated prematurely after recruitment of 7392 patients because of an increase in major bleeding events with apixaban in the absence of a counterbalancing reduction in recurrent ischemic events. With a median follow-up of 241 days, the primary outcome of cardiovascular death, myocardial infarction, or ischemic stroke occurred in 279 of the 3705 patients (7.5%) assigned to apixaban (13.2 events per 100 patient-years) and in 293 of the 3687 patients (7.9%) assigned to placebo (14.0 events per 100 patient-years) (hazard ratio with apixaban, 0.95; 95% confidence interval [CI], 0.80 to 1.11; P=0.51). The primary safety outcome of major bleeding according to the Thrombolysis in Myocardial Infarction (TIMI) definition occurred in 46 of the 3673 patients (1.3%) who received at least one dose of apixaban (2.4 events per 100 patient-years) and in 18 of the 3642 patients (0.5%) who received at least one dose of placebo (0.9 events per 100 patient-years) (hazard ratio with apixaban, 2.59; 95% CI, 1.50 to 4.46; P=0.001). A greater number of intracranial and fatal bleeding events occurred with apixaban than with placebo. The addition of apixaban, at a dose of 5 mg twice daily, to antiplatelet therapy in high-risk patients after an acute coronary syndrome increased the number of major bleeding events without a significant reduction in recurrent ischemic events.

    Full Text Available Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05. Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    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.

    Centurión, Osmar Antonio

    2016-03-01

    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

    Full Text Available noBackground & Objectives: The postoperative Low T3 syndrome has been considered as a possible source of reduced myocardial contractility, resulting in increased mortality after CABG. Effect of preoperative Low T3 has not been well studied in patients undergoing CABG surgery. Aim of our study is to evaluate effect of preoperative Low T3 syndrome in patients undergoing CABG surgery.Materials & Methods: Six hundred and six patients undergoing CABG were included in this prospective study. The impact of the base-line FT3 concentration and of preoperative low T3 syndrome on the risk of postoperative low cardiac output and hospital death was analyzed.Results: Fifteen patients (2.3% postoperatively and 159 (26.2% developed major complications. At univariate analysis a reduced EF, the presence of peripheral vascular disease, the NYHA class, the surgical urgency, the aortic cross-clamp time, the CPB time and the FT3 concentration at admission were significantly associated with low CO and higher mortality. At multivariate analysis, the CPB time, an emergency procedure, a reduced LVEF, and the fT3 concentration were independently related to the development of low CO. However, in multivariate analysis low EF, and the fT3 concentration were the only predictors of hospital death.Conclusion: We conclude that preoperative low EF and low T3 syndrome independently causes low cardiac output and higher mortality in patients undergoing CABG. Therefore, all patients undergoing CABG should be evaluated for low T3 syndrome and patients with low T3 syndrome should be considered at increased risk. Appropriate preoperative T3 replacement therapy could decrease the postoperative complications in patients undergoing CABG.JCMS Nepal. 2015; 11(2:1-7

    Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001). Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable. PMID:22558552

    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.

    We aimed to elucidate the relationship between mild to moderate renal impairements and burden of atherosclerosis in patients with acute coronary syndrome (ACS). A total of 380 patients with ACS were included in the study. Gensini and SYNTAX scores were also calculated. Kidney function was classified based on estimated glomerular filtration rate (eGFR) into stage 1: eGFR >90, stage 2: 60 to 89, and stage 3: 30 to 60 mL/min per 1.73 m(2). Gensini and SYNTAX scores were higher in stages 2 and 3 than in stage 1. Also, the number of diseased vessels, number of critical lesions (>50 and 70%), left main disease, and number of total occlusion vessels were higher in stages 2 and 3 than in stage 1. Multivariate linear regression analysis demonstrated that a decreased eGFR was an independent risk factor for SYNTAX and Gensini scores together with age and male gender.

    Full Text Available Coronary Artery Disease (CAD is becoming a major cause of morbidity & mortality burden in the developing world. Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

    Full Text Available Acute coronary syndrome (ACS describes the range of myocardial ischemic states that includes unstable angina, non-ST elevated myocardial infarction (MI, or ST-elevated MI. ACS is associated with substantial morbidity and mortality and places a large financial burden on the health care system. The diagnosis of ACS begins with a thorough clinical assessment of a patient's presenting symptoms, electrocardiogram and cardiac troponin levels as well as a review of past medical history. Early risk stratification can assist clinicians in determining whether an early invasive management strategy or an initial conservative strategy should be pursued and can help determine appropriate pharmacologic therapies. Key components in the management of ACS include coronary revascularization when indicated; prompt initiation of dual antiplatelet therapy and anticoagulation; and consideration of adjuvant agents including beta blockers, inhibitors of the renin angiotensin system, and HmG-coenzyme A reductase inhibitors. It is essential for clinicians to take an individualized approach to treatment and consider long-term safety and efficacy when managing patients with a history of ACS after hospital discharge. This review identifies promising new or emerging techniques, as well as established tools, and reviews their current or potential role in clinical practice.

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

    Full Text Available Background and Objective: Coronary angiography is one of the most common diagnostic procedures in cardiac patients that can increase the level of anxiety. Anxiety also is a risk factor for cardiac disease. The present study aimed to determine the effect of acupressure at the hearts shenmen (HE-7 and the third eye (Yintang on anxiety in patients undergoing coronary angiography. Materials and Method: This randomized controlled trial was conducted on patients undergoing coronary angiography in one of the hospitals in Rafsanjan in 2015. 135 patients were randomly divided into three groups of 45 people. Two intervention groups received acupressure 30 minutes before angiography for 5 minutes in point's yintang and hearts shenmen and control group received acupressure on false points near the thenar muscles. Anxiety of patients was measured one hour before and 10 minutes after the intervention. Data collection tools were including demographic form and Spielberger's questionnaire. Data analysis was done using SPSS 18 and paired t-tests, independent T-test, and ANOVA. Results: After intervention the mean score of anxiety in the yintang group was decreased from 70.53±16.3 to 62.06±13.4 and in hearts shenmen group from 67.80±14.9 to 60.46±15.2 (p<0/001. This difference between intervention and control groups was significant (p=0.04. Conclusion: Acupressure is effective in reducing anxiety in patients undergoing coronary angiography, thus it is recommended as a method for reducing the anxiety before angiography.

    Ischemic heart disease presents different features in men and women. We analyzed the relation between gender and prognosis in patients who had suffered a high-risk acute coronary syndrome (ACS). This was a prospective analytical cohort study performed at Lozano Blesa University Hospital, Zaragoza, Spain, of 559 patients diagnosed with high-risk ACS with and without ST-segment elevation according to the American College of Cardiology/American Heart Association guidelines. The sample was divided into two groups by gender and differences in epidemiologic, laboratory, electrocardiographic and echocardiographic variables and treatment were recorded. A Cox's proportional hazard model was applied and 6-month mortality was analyzed as the main variable. The median age was 65.2±12.7 years, and 21.8% were women. Baseline characteristics in women were more unfavorable, with higher GRACE scores, older age, higher prevalence of hypertension, diabetes and heart failure, lower ejection fraction and more renal dysfunction at admission. Women suffered more adverse cardiovascular events (27.9% vs. 15.8%, p=0.002). Sixty-four patients died, 18.9% of the women vs. 9.4% of the men (p=0.004). After multivariate analysis, female gender did not present an independent relation with mortality. Hemoglobin level, renal function, ejection fraction and Killip class >1 presented significant differences. Acute syndrome coronary in women has a worse prognosis than in men. Their adverse course is due to their baseline characteristics and not to their gender. Copyright © 2012 Sociedade Portuguesa de Cardiologia. Published by Elsevier España. All rights reserved.

    There is wide variation in the use of radial over femoral access for patients with ACS. This study evaluates the factors associated with the selection of radial versus femoral angiography in Australia and New Zealand and the effect of access site on clinical events in acute coronary syndrome (ACS) patients. An analysis of the SNAPSHOT ACS audit was conducted during May 2012 across 286 hospitals in Australia and New Zealand. Data collected included baseline patient characteristics, hospital site details, treatment received, clinical events in-hospital and mortality at 18 months. Univariate and multivariable analyses were performed. Of the 1621 patients undergoing coronary angiography, access was through the femoral artery in 1043 (63%), and the radial in 578 (36%) patients. Radial access dominated in New Zealand (241 out of 327, 73.7%), compared to Australia (337 out of 1293, 26.1%, p=209 cases per year) (OR 1.86, 95% CI 1.06-3.26, p=0.03). After adjustment, there was no difference in clinical events in-hospital or mortality at 18 months CONCLUSION: Coronary angiography in New Zealand rather than Australia is the strongest predictor of radial access in ACS patients. There was no difference in outcomes according to access site in this population based cohort study. Copyright © 2016. Published by Elsevier B.V.

    Low responsiveness to clopidogrel (LRC) is associated with increased risk of ischemic events. This study was aimed to explore the feasibility of tailored antiplatelet therapy according to the responsiveness to clopidogrel. A total of 305 clopidogrel naïve patients with acute coronary syndromes (ACS) undergoing coronary stenting were randomly assigned to receive standard (n = 151) or tailored (n = 154) antiplatelet therapy. The ADP-induced platelet aggregation tests by light transmission aggregometry were performed to identify LRC patients assigned to the tailored group. The standard antiplatelet regimen was dual antiplatelet therapy with aspirin and clopidogrel. The tailored antiplatelet therapy was standard regimen for non-LRC patients and an additional 6-month cilostazol treatment for LRC patients. The primary efficacy outcome was the composite of cardiovascular death, myocardial infarction or stroke at one year. LCR was present in 26.6% (41/154) of patients in the tailored group. The percentage platelet aggregation for LCR patients was significantly decreased at three days after adjunctive cilostazol treatment (77.5% ± 12.1% vs. 64.5% ± 12.1%, P antiplatelet therapy for ACS patients after coronary stenting according to responsiveness to clopidogrel is feasible. However, its efficacy and safety need further confirmation by clinical trials with larger sample sizes.

    Mean platelet volume (MPV) is an indicator of platelet activation which is a central process in the pathophysiology of coronary heart disease. The metabolic syndrome (MS) is characterized as the clustering of closely associated and interdependent atherosclerotic risk factors. MS has also been shown to be strongly associated with poor outcome in patients with coronary artery disease (CAD). The present study was designed to investigate MPV values in patients MS and to interrogate the association with CAD. We measured MPV in 205 consecutive patients with metabolic syndrome (mean age, 53+/-7 years) and 140 control subjects without metabolic syndrome (mean age, 52+/-6 years). All patients were selected from individuals who underwent coronary angiography in our hospital with a suspicion of coronary artery disease. To evaluate the severity of coronary artery disease, the patients with MS were subdivided depending upon the coexistence of coronary artery disease: normal coronary arteries, having coronary stenotic lesions of 50%. The MPV was significantly higher in patients with MS than in the control group (10.19+/-1.49 fl vs 8.21+/-1.02 fl, p<0.001). According to the CAD severity, there were no statistically significant differences in MPV among these subgroups. We have shown for the first time that patients with MS have higher MPV compared to control subjects with normal coronary angiograms and to be associated with CAD. Hence MPV can be used as a follow up marker in patients with MS in the point of CAD.

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

    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.

    Despite growing recognition of type 2 myocardial infarction (T2MI; related to supply/demand mismatch), little is known about its risk factors or its association with outcome. A single-center cohort of patients undergoing coronary or peripheral angiography with or without intervention was prospectively enrolled and followed for incident type 1 and T2MI, and major adverse cardiovascular events (MACE, a composite of all-cause death, nonfatal myocardial infarction [MI], heart failure, stroke, transient ischemic attack, peripheral arterial complication, and cardiac arrhythmia), as well. T2MI was adjudicated using criteria from the Third Universal Definition of MI. Baseline characteristics, blood samples, and angiography information were obtained. Major end points subsequent to first MI were assessed using landmark analyses to compare the rates of first events only where everyone with a prior history of any MACE before MI were censored and adjusted for follow-up times. Cox proportional hazard models were used for time-to-event analyses with age and sex forced into all models and additional covariates evaluated by using the stepwise option for the selection. One thousand two hundred fifty-one patients were enrolled and followed for a median of 3.4 years. Of these patients, 152 (12.2%) had T2MI during follow-up; T2MI was frequently recurrent. Multivariable predictors of T2MI were older age, lower systolic blood pressure, history of coronary artery disease, heart failure, chronic obstructive pulmonary disease, diabetes mellitus, nitrate use, and elevated concentrations of glucose, N-terminal pro-B type natriuretic peptide, and cystatin C. Patients with T2MI had higher rates of subsequent adverse events than those without T2MI (per 100 person-years: MACE, 53.7 versus 21.1, P<0.001; all-cause death, 23.3 versus 3.3, P<0.001; cardiovascular death, 17.5 versus 2.6, P<0.001; heart failure events, 22.4 versus 7.4, P<0.001); these rates are similar to those seen in patients with

    This was a study of the pre-operative factors that influence quality of life (QoL) in patients with coronary artery disease and the relationship between pre-operative QoL and early outcome after coronary artery bypass surgery (CABG). Using the WHOQOL-BREF questionnaire, 283 patients who underwent isolated coronary artery bypass surgery were interviewed and scores were obtained for the physical, psychological, social and environmental components. The study found that the independent physical component predictors for higher QoL included male gender and diabetes mellitus, while the independent psychological component predictors were male gender and high ejection fraction. Males, diabetics and patients with low education levels had higher social well-being than others. Among the postoperative complications, only respiratory failure was found to have a relationship with physical and psychological components. Women with coronary artery disease who were candidates for CABG had lower scores than the men in respect of all components of QoL. Furthermore, a lower pre-operative psychological score in patients undergoing CABG can influence postoperative complications, especially respiratory failure.

    Jatti, Kumar; Paisey, Richard; More, Ranjit

    2012-01-01

    Alström syndrome (ALMS) is a rare autosomal recessive condition, caused by mutations in the ALMS1 gene located on the short arm of chromosome 2. This gene codes for a protein linked with the centrosome, whose precise function is unknown. This condition was first described by Alström in 1959. ALMS is a multisystem condition that is characterised by childhood onset of blindness secondary to rod-cone retinal degeneration and dilated cardiomyopathy with heart failure, which often presents in infanthood and may recur later in life. Metabolic abnormalities including hypertriglyceridemia, liver steatosis, insulin resistance and type 2 diabetes mellitus are common, often occurring in association with obesity. Other abnormalities include endocrinological disturbances, such as thyroid disorder, growth hormone deficiency, hypogonadism and, in women, hyperandrogenism. This syndrome is also associated with sensorineural hearing loss, renal failure secondary to glomerulo-fibrosis, and fibrotic lung disease. Multiorgan fibrotic infiltration is the common feature in all cases. Considering the history of diabetes, hypertension, dyslipidemia, obesity and renal dysfunction in ALMS, it would be expected that this group of patients could develop coronary artery disease (CAD). But such cases have not been reported so far. We report a case of premature onset of CAD in one of the longest surviving patient with ALMS.

    Immunosuppressant agents such as calcineurin inhibitors (CNI) used after solid organ transplantation may cause endothelial dysfunction, and coronary and renal arterial vasospasm. We report a patient presenting acute ST segment elevation myocardial infarction (STEMI) at the second week of renal transplantation. In the case of STEMI in patients with solid organ transplants under immunosuppressive therapy with CNI, coronary vasospasm associated with these drugs should be kept in mind before starting any interventional procedure. High dose nitroglycerine may immediately resolve tacrolimus or cyclosporine A induced coronary vasospasm. Calcium channel blockers should immediately be added to treatment because of the short half-life of nitroglycerine. PMID:26161107

    To evaluate the efficiency and safety of emergency department (ED) coronary computed tomography angiography (CTA) during a 3-year clinical experience. Single-center registry of coronary CTA in consecutive ED patients with suspicion of acute coronary syndrome (ACS). The primary outcome was efficiency of coronary CTA defined as the length of hospitalization. Secondary endpoints of safety were defined as the rate of downstream testing, normalcy rates of invasive coronary angiography (ICA), absence of missed ACS, and major adverse cardiac events (MACE) during follow-up, and index radiation exposure. One thousand twenty two consecutive patients were referred for clinical coronary CTA with suspicion of ACS. Overall, median time to discharge home was 10.5 (5.7-24.1) hours. Patient disposition was 42.7 % direct discharge from the ED, 43.2 % discharge from emergency unit, and 14.1 % hospital admission. ACS rate during index hospitalization was 9.1 %. One hundred ninety two patients underwent additional diagnostic imaging and 77 underwent ICA. The positive predictive value of CTA compared to ICA was 78.9 % (95 %-CI 68.1-87.5 %). Median CT radiation exposure was 4.0 (2.5-5.8) mSv. No ACS was missed; MACE at follow-up after negative CTA was 0.2 %. Coronary CTA in an experienced tertiary care setting allows for efficient and safe management of patients with suspicion for ACS. • ED Coronary CTA using advanced systems is associated with low radiation exposure. • Negative coronary CTA is associated with low rates of MACE. • CTA in ED patients enables short median time to discharge home. • CTA strategy is characterized by few downstream tests including unnecessary ICA.

    Full Text Available Objectives: The present study was conducted to evaluate the cardioprotective effect of sevoflurane compared with propofol in patients with coronary artery disease (CAD undergoing peripheral vascular surgery; and to address the question whether a volatile anesthetic might improve cardiac outcome in these patients. Methods: One hundred twenty-six patients scheduled for elective peripheral vascular surgery were prospectively randomized to receive either sevoflurane inhalation anesthesia or total intravenous anesthesia. ST-segment monitoring was performed continuously during intra- and post-operative 48 h periods. The number of ischemic events and the cumulative duration of ischemia in each patient were recorded. Blood was sampled in all patients for the determination of cTnI. Samples were obtained before the induction of anesthesia, on admission to the ICU, and at 6, 12, 24, and 48 h after admission to the intensive care unit (ICU. Patients were followed-up during their hospital stay for any adverse cardiac events. Results: The incidence of ischemia were comparable among the groups [16 (25% patients in sevoflurane group vs 24 (39% patients in propofol group; P=0.126]. Duration, cumulative duration, and magnitude of ST-segment depression of ischemic events in each patient were significantly less in sevoflurane group (P=0.008, 0.048, 0.038, respectively. cTnI levels of the overall population were significantly less in sevoflurane group vs propofol group (P values <0.0001 from 6 h postoperative and onward. Meanwhile, cTnI levels at 6, 12, 24, and 48 h after admission to the ICU in patients who presented with ischemic electrocardiographic (ECG changes were significantly lower in sevoflurane group than in the propofol group (P<0.0001, <0.0001, <0.0001, 0.0003. None of the patients presented with unstable angina, myocardial infarction, congestive heart failure, or serious arrhythmia either during ICU or hospital stay. Conclusion: Patients with CAD

    Objective: To explore the patterns of Syndrome Differentiation (SD) of coronary heart disease (CHD) patients in peri-operative stage of coronary artery bypass graft (CABG). Methods: One week after operation, thirty-seven CHD patients, who received CABG of internal mammary artery or great saphena vein under conventional general anesthesia with low or middle temperature extracorporeal circulation were differentiated as various syndromes, with the pre- or post-operational EKG, color Doppler echocardiography were done during and after operation. The hemodynamic parameters were monitored. Results: In the CHD patients, 64.9% were differentiated as Qi-Yin deficiency, 67.6% were complicated with phlegm syndrome and 62.2% with blood stasis, suggesting that Qi-deficiency, phlegm and stasis are the basic pathogenetic factors in patients with CABG. Moreover, the peri-operative syndrome was correlated with the condition of coronary artery lesion, heart and lung functions before operation, and the extracorporeal circulation time during the operation. Conclusion: TCM SD conducting in peri-operative stage might be useful in exploring the patterns of syndrome alteration which provided a basis for preventing peri-operative complications and elevating success rate of operation.

    Noonan syndrome is a constellation of congenital malformations including heart defects, facial anomalies and short stature. The cardiovascular defects are variable and extensive, with the most common being pulmonary stenosis and hypertrophic cardiomyopathy. Coronary artery anomalies have only been reported in a few cases. We report a child with Noonan syndrome status post pulmonary stenosis and atrial septal defect repair, who developed bilateral coronary artery aneurysms. The aneurysms were diagnosed with both cardiac magnetic resonance imaging and coronary computed tomography angiography. There had been no evidence of them on a cardiac MR exam 5 years previously.

    Full Text Available Introduction: Metabolic syndrome (MS is considered as an important risk factor for advanced coronary artery disease. This condition can increase the mortality and morbidity in the patients undergoing coronary artery bypass graft (CABG surgery. The aim of the study was compared mortality and morbidity after off Pump- CABG surgery between patients with and without the Metabolic syndrome. Materials & Methods: This prospective cross-sectional study was conducted on 120 patients, who underwent off-pump CABG surgery between October 2014-October 2016. The participants were equally divided into two groups including the patients with and without MS (MS and non-MS, respectively. Results: According to the results, 68 (56.6% patients were male. Furthermore, out of the 60 participants with MS, 36 (60% cases were male. The mean ages of the MS and non-MS groups were 64.96±9.6 and 65.62±10.6 P=0.6 years, respectively. No statistically significant difference was observed between the two groups in terms of the mortality and morbidity (e.g., surgical wound infection, length of Intensive Care Unit and hospital stay, atrial fibrillation rhythm, and bleeding in the first 24 h. The intubation time in patients with Metabolic Syndrome was significantly higher than patients without Metabolic Syndrome (6.66 ± 1.97 vs 5.83 ± 1.93 respectively; P=0.007 Conclusion: Metabolic syndrome was not associated with higher mortality and morbidity after CABG surgery compare to patients without Metabolic syndrome, although patients with Metabolic syndrome had higher risk for long intubation time.

    Although numerous risk factors have been established to predict the development of acute coronary syndrome (ACS), the risk factor profile may be different between the younger and older individuals. To analyse the frequency and pattern of atherogenic risk factors and angiographic profiles in age-stratified Gujarati patients with ACS. ACS patients undergoing coronary angiography at U.N. Mehta Institute of Cardiology and Research, Gujarat, India between January 2008 and December 2012 were classified in to two age groups with 40y as cut-off. Patients were assessed for conventional risk factors (diabetes mellitus, dyslipidaemia, hypertension, smoking, obesity), novel risk factors (high sensitivity C-reactive protein, lipoprotein (a), homocysteine), and angiographic profiles.The statistical difference between two age groups was determined by Student's t-test for continuous variables and Chi-square or Fisher's exact test for categorical variables. A total of 200 patients, 100 patients ≤40 y of age and 100 patients >40 y of age, were evaluated. Older patients had higher frequency of hypertension (32 vs. 16%, p=0.008), while family history of coronary artery disease was more common among younger patients (19 vs. 9%, p=0.041). The incidence of diabetes, dyslipidaemia, smoking and tobacco chewing did not vary significantly between the two groups. Total cholesterol and low-density lipoprotein cholesterol levels were significantly higher in the younger group (p<0.05). Lipoprotein (a), homocysteine and high-sensitivity C reactive protein levels were comparable between two age groups. Multi-vessel coronary artery disease was more common among older group. The most commonly affected coronary artery was the left anterior descending artery among younger patients (44%) and the left circumflex artery among older patients (38.1%). Young patients with ACS had different atherosclerotic risk profile and less extensive coronary artery disease as compared to older counterparts. Emphasis

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.

    Mechanical compression of coronary artery stents may be associated with a fatal outcome as the result of refractory myocardial ischemia. We present the history of an 83-yr-old patient, who died owing to hemorrhagic shock 3 days after stent implantation, despite immediate cardiopulmonary resuscitation (CPR). Postmortem examination showed stent compression, probably due to mechanical deformation during CPR. This complication has been reported in two other cases in the literature, suggesting that CPR may be hazardous to patients with coronary artery stents.

    Background Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). Objective To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged dehumanization (De) and professional fulfillment (PF). The Lipp’s Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Results Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital. PMID:25517388

    Kidney disease and cardiovascular disease seem to be lethally synergistic and both are approaching the epidemic level. A reduced glomerular filtration rate is associated with increased mortality risk in patients with heart failure. Many patients with congestive heart failure are anemic. Anemia is very often associated with chronic kidney disease. To assess--in relation to New York Heart Association class--the prevalence of anemia and chronic kidney disease in patients with normal serum creatinine in a cohort of 526 consecutive patients with coronary artery disease undergoing percutaneous coronary interventions. GFR was estimated using the simplified MDRD formula, the Cockcroft-Gault formula, the Jeliffe and the novel CKD-EPI formula. According to the WHO definition the prevalence of anemia in our study was 21%. We observed a progressive decline in GFR and hemoglobin concentration together with a rise in NYHA class. Significant correlations were observed between eGFR and systolic blood pressure, diastolic blood pressure, age, NYHA class, complications of PCI, including bleeding, and major adverse cardiac events. The prevalence of anemia and chronic kidney disease is high in patients undergoing PCI despite normal serum creatinine, particularly in higher NYHA class. Lower eGFR and hemoglobin are associated with more complications, including bleeding after PCI and higher prevalence of major adverse cardiac events. In patients with risk factors for cardiovascular disease, GFR should be estimated since renal dysfunction and subsequent anemia are important risk factors for cardiovascular morbidity and mortality.

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.

    to investigate the factors associated with mortality in patients undergoing coronary artery bypass grafting in a cardiovascular referral hospital in Santa Catarina. quantitative, exploratory, descriptive and retrospective study. The medical records of 1447 patients, from 2005 to 2013, were analyzed for statistically related variables, these being: profile, hospitalization diagnosis, risk factors for coronary artery disease, complications recorded during the hospitalization, length of hospitalization and cause of death. the mortality rate was 5.3% during the study period. Death was more common in females and those of black skin color, with a mean age of 65 years. Acute myocardial infarction was the most common hospitalization diagnosis. The majority of the complications recorded during hospitalization were characterized by changes in the cardiovascular system, with longer hospitalization periods being directly related to death from septic shock. the data provide subsidies for nursing work with preventive measures and early detection of complications associated with coronary artery bypass grafting. This reinforces the importance of using the data as quality indicators, aiming to guarantee care guided by reliable information to guide managers in planning patient care and high complexity health services. conhecer os fatores associados à mortalidade de pacientes submetidos à cirurgia de revascularização do miocárdio em hospital referência cardiovascular em Santa Catarina. estudo quantitativo, exploratório, descritivo e retrospectivo.

    Coronary artery calcification (CAC), an indicator of coronary artery stenosis, is an independent risk factor of ischemic heart disease. Smoking increases the risk of metabolic syndrome (MS) and cardiovascular disease. Almost no previous studies have evaluated the combined effect of MS and smoking status on CAC. Therefore, in this study we examined the relationships between CAC, MS, and smoking. This study included 775 adult males without histories of cardiovascular disease who visited the Health Promotion Center at the University Hospital in Gyeonggi-do, Republic of Korea from January 2, 2010 to December 31, 2012. All subjects were screened for CAC by multi-detector computed tomography (MDCT). CAC increased significantly with age and body mass index (BMI). Among MS components, abdominal obesity and elevated fasting blood glucose were correlated with CAC. After adjusting for age and BMI, MS was associated with a 1.46-fold increase in CAC (95% CI:1.02-2.09), abdominal obesity was associated with a 1.45-fold increase (95% CI:1.04-2.04), elevated fasting blood glucose was associated with a 2-fold increase (95% CI:1.36-2.94), and MS and smoking combined were associated with 2.44-fold increase in CAC. Thus, the combination of smoking and MS had a greater impact on CAC than any single factor alone. MS is correlated with an increased risk of CAC, and a combination of MS and smoking is associated with even greater risk. These findings can be used to prevent cardiovascular disease in adults.

    Full Text Available BACKGROUND: Acute coronary syndrome (ACS is common in patients approaching the end-of-life (EoL, but these patients rarely receive palliative care. We compared the utility of a palliative care prognostic tool (Gold Standards Framework (GSF and the Global Registry of Acute Coronary Events (GRACE score, to help identify patients approaching EoL. METHODS AND FINDINGS: 172 unselected consecutive patients with confirmed ACS admitted over an eight-week period were assessed using prognostic tools and followed up for 12 months. GSF criteria identified 40 (23% patients suitable for EoL care while GRACE identified 32 (19% patients with ≥ 10% risk of death within 6 months. Patients meeting GSF criteria were older (p = 0.006, had more comorbidities (1.6 ± 0.7 vs. 1.2 ± 0.9, p = 0.007, more frequent hospitalisations before (p = 0.001 and after (0.0001 their index admission, and were more likely to die during follow-up (GSF+ 20% vs GSF- 7%, p = 0.03. GRACE score was predictive of 12-month mortality (C-statistic 0.75 and this was improved by the addition of previous hospital admissions and previous history of stroke (C-statistic 0.88. CONCLUSIONS: This study has highlighted a potentially large number of ACS patients eligible for EoL care. GSF or GRACE could be used in the hospital setting to help identify these patients. GSF identifies ACS patients with more comorbidity and at increased risk of hospital readmission.

    Background Major Depressive Disorder (MDD) is one of the most common mental illnesses in psychiatry, being considered a risk factor for Acute Coronary Syndrome (ACS). Objective To assess the prevalence of MDD in ACS patients, as well as to analyze associated factors through the interdependence of sociodemographic, lifestyle and clinical variables. Methods Observational, descriptive, cross-sectional, case-series study conducted on patients hospitalized consecutively at the coronary units of three public hospitals in the city of Rio de Janeiro over a 24-month period. All participants answered a standardized questionnaire requesting sociodemographic, lifestyle and clinical data, as well as a structured diagnostic interview for the DSM-IV regarding ongoing major depressive episodes. A general log-linear model of multivariate analysis was employed to assess association and interdependence with a significance level of 5%. Results Analysis of 356 patients (229 men), with an average and median age of 60 years (SD ± 11.42, 27-89). We found an MDD point prevalence of 23%, and a significant association between MDD and gender, marital status, sedentary lifestyle, Killip classification, and MDD history. Controlling for gender, we found a statistically significant association between MDD and gender, age ≤ 60 years, sedentary lifestyle and MDD history. The log-linear model identified the variables MDD history, gender, sedentary lifestyle, and age ≤ 60 years as having the greatest association with MDD. Conclusion Distinct approaches are required to diagnose and treat MDD in young women with ACS, history of MDD, sedentary lifestyle, and who are not in stable relationships. PMID:28443957

    Full Text Available Background and Objective: Patients experience severs pain after cardiac surgery due to incision of anatomical components of the chest wall. Given that the cryotherapy is one of the simplest and cheapest non-pharmacological methods of pain relief, the current study was conducted to determine the effect of cryotherapy on the severity of thoracic pain in patients undergoing coronary artery bypass grafting surgery. Materials and Method: This clinical trial study was conducted on 50 patients undergoing coronary artery bypass grafting surgery in one of the educational hospitals in Zahedan in 2015. Patients were selected conveniently and then were randomly allocated into two intervention and control groups (each group containing 25 patients. At first, pain of patients was measured in two groups after three cycles of deep breathing and coughing by using visual analogue scale. In intervention group, ice pack was used on the chest wound dressing of patients for 20 minutes alternatively at 5 minutes intervals in intervention group. Then, both groups received emotional support for 15 minutes and the pain score was measured again. Data were analyzed using Chi-square, independent t-test, Paired t-test, and analysis of covariance tests in SPSS 21. Results: The mean pain score before the intervention in the intervention and control groups were 60.16±13.45 and 58.64 ± 14.42, respectively. These values were changed after cryotherapy to 45.16 ± 15.25 in the intervention group and 58.60 ± 14.40 in the intervention group (P < 0.001. Conclusion: The use of cryotherapy can reduce severity of Thoracic Pain related to coughing and deep breathing in patients undergoing coronary artery bypass grafting surgery. Therefore, this method can be used as a non-pharmacological method of pain relief.

    Layer-specific strain allows the assessment of the function of every layer of myocardium. To evaluate the changes of non-ST-segment elevation acute coronary syndrome(NSTE-ACS) patients with and without complex coronary artery disease(CAD) by layer-specific strain and determine if myocardial strain can identify complex CAD and assess the severity of coronary lesions as defined by Syntax score (SS). A total of 139 patients undergoing coronary angiography due to suspected NSTE-ACS were prospectively enrolled. Echocardiography was performed 1h before angiography. Global longitudinal strain (GLS), territorial longitudinal strain (TLS), global circumferential strain (GCS) and territorial circumferential strain (TCS) of the three layers of LV wall were assessed by two-dimensional (2D) speckle tracking echocardiography (STE) with layer-specific myocardial deformation quantitative analysis based on the perfusion territories of the three major coronary arteries in an 18-segment model of LV. SS was used for predicting the severity of coronary lesions in patients with complex CAD. 78 had complex CAD, 32 had 1- or 2-vessel disease and 29 had no significant coronary stenosis confirmed by coronary angiography. According to SS value, 78 complex CAD subjects were subdivided into three groups, 24 in group SS1 (SS≤22), 26 in group SS2 (SS 23-32) and 28 in group SS3 (SS≥33). Compared to the other two groups without complex CAD, patients with NSTE-ACS due to complex CAD had worse function in all 3 myocardial layers assessed by GLS, TLS, GCS and TCS. Endocardial GLS and TLS (all, PCAD than in those without (all, PCAD and predict the severity of coronary lesions in patients with NSTE-ACS. Copyright © 2016 Elsevier Ireland Ltd.

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

    Introduction: The presence of metabolic syndrome in men with prostate cancer (PCa) undergoing androgen-deprivation therapy (ADT), especially intermittent type, has not been completely evaluated. The aim of this study is to evaluate metabolic syndrome in men with PCa undergoing intermittent ADT. Methods: In this longitudinal study, we studied the prevalence of metabolic syndrome and its components in 190 patients who were undergoing intermittent ADT. The metabolic syndrome was defined according to the Adult Treatment Panel III criteria. All metabolic parameters, including lipid profile, blood glucose, blood pressures, and waist circumferences of the patients were measured six and 12 months after treatment. Results: Mean age of the patients was 67.5 ± 6.74 years. The incidence of metabolic syndrome after six and 12 months was 6.8% and 14.7%, respectively. Analysis of various components of the metabolic syndrome revealed that patients had significantly higher overall prevalence of hyperglycemia, abdominal obesity, and hypertriglyceridemia in their six- and 12-month followups, but blood pressure has not been changed in the same period except for diastolic blood pressure after six months. Conclusions: Although there was an increased risk of metabolic syndrome in patients receiving intermittent ADT, it was lower than other studies that treated the same patients with continuous ADT. Also it seems that intermittent ADT has less metabolic complications than continuous ADT and could be used as a safe alternative in patients with advanced and metastatic PCa. PMID:27695584

    Full Text Available Epidural analgesia is widely used in cardiothoracic surgery. Most of the complications associated with epidural analgesia are related to the insertion techniques of epidural catheter. A 68-year-old obese patient posted for coronary artery bypass grafting surgery developed headache followed by seizures after insertion of the thoracic epidural catheter. Magnetic resonance imaging revealed air in the basal cisterns and in the left frontal region. The patient was managed conservatively and the symptoms subsided after 24 h. Later, the patient underwent coronary angioplasty.

    Objectioe To observe the dynamic changes of the plasma ET-1 and the effect of low dose nitroglycerin in patients with coronary artery bypass surgery. Methods Forty patravenous nitroglycerin 1 μg @ kg-1 @ rain-1 perioperatively. RIA was used to assay the plasma ET-1 lev-el. All the hemodynamie parameters were recorded by the Swan-Ganze catheter. Results The preoperative plasma ET-1 level in patients with coronary artery disease was significantly higher than the normal level. Five minutes after cardiopalmouary bypass in these patients the plasma ET-1 level was increased significantly until 6 to 8 h after operation. The increasing plasma ET-1 level in group B was less intense than that in group A. There was a positive correlation between the plasma ET-1 level and the mean pulmonary artery pressure in group A 2 and 8 h after operation. Conclusion In patients undergoing coronary artery bypass surgery, the increased plasma ET-1 level may be due to the influence of cardiopulmonary bypass partly. Low dose nitroglycerin is beneficial to these patients.

    The purpose of this study was to determine the diagnostic test characteristics of serum neuregulin-1β (NRG-1β) for the detection of acute coronary syndrome (ACS). We recruited emergency department patients presenting with signs and symptoms prompting an evaluation for ACS. Serum troponin and neuregulin-1β levels were compared between those who had a final discharge diagnosis of myocardial infarction (STEMI and NSTEMI) and those who did not, as well as those who more broadly had a final discharge diagnosis of ACS (STEMI, NSTEMI, and unstable angina). Of 319 study participants, 11% had evidence of myocardial infarction, and 19.7% had a final diagnosis of ACS. Patients with MI had median neuregulin levels of 0.16 ng/mL (IQR [0.16–24.54]). Compared to the median of those without MI, 1.46 ng/mL (IQR [0.16–15.02]), there was no significant difference in the distribution of results (P = 0.63). Median neuregulin levels for patients with ACS were 0.65 ng/mL (IQR [0.16–24.54]). There was no statistical significance compared to those without ACS who had a median of 1.40 ng/mL (IQR [0.16–14.19]) (P = 0.95). Neuregulin did not perform successfully as a biomarker for acute MI or ACS in the emergency department. PMID:27110055

    Acute coronary syndrome (ACS) is a serious condition arising from an imbalance of supply and demand to meet myocardium's metabolic needs. Patients typically present with retrosternal chest pain radiating to neck and left arm. Electrocardiography (ECG) and laboratory tests are used indiagnosis. However in emergency departments, there are some difficulties for physicians to decide whether hospitalizing, following up or discharging the patient. The aim of the study is to diagnose ACS and helping the physician with his decisionto discharge or to hospitalizevia machine learning techniques such as support vector machine (SVM) by using patient data including age, sex, risk factors, and cardiac enzymes (CK-MB, Troponin I) of patients presenting to emergency department with chest pain. Clinical, laboratory, and imaging data of 228 patients presenting to emergency department with chest pain were reviewedand the performance of support vector machine. Four different methods (Support vector machine (SVM), Artificial neural network (ANN), Naïve Bayes and Logistic Regression) were tested and the results of SVM which has the highest accuracy is reported. Among 228 patients aged 19 to 91 years who were included in the study, 99 (43.4 %) were qualified as ACS, while 129 (56.5 %) had no ACS. The classification model using SVM attained a 99.13 % classification success. The present study showed a 99.13 % classification success for ACS diagnosis attained by Support Vector Machine. This study showed that machine learning techniques may help emergency department staff make decisions by rapidly producing relevant data.

    Hyperglycemia is a frequent condition in patients with acute coronary syndromes (ACS). Hyperglycemia during ACS is caused by an inflammatory and adrenergic response to ischemic stress, when catecholamines are released and glycogenolysis induced. Although the involved pathophysiological mechanisms have not yet been fully elucidated, it is believed that hyperglycemia is associated with an increase in free fat acids (which induce cardiac arrhythmias), insulin resistance, chemical inactivation of nitric oxide and the production of oxygen reactive species (with consequent microvascular and endothelial dysfunction), a prothrombotic state, and vascular inflammation. It is also related to myocardial metabolic disorders, leading to thrombosis, extension of the damaged area, reduced collateral circulation, and ischemic preconditioning. In the last few years, several observational studies demonstrated that hyperglycemia in ACS is a powerful predictor of survival, increasing the risk of immediate and long-term complications in patients both with and without previously known diabetes mellitus. Glucose management strategies in ACS may improve outcomes in patients with hyperglycemia, perhaps by reducing inflammatory and clotting mediators, by improving endothelial function and fibrinolysis and by reducing infarct size. Recent clinical trials of insulin in ACS have resulted in varying levels of benefit, but the clinical benefit of an aggressive treatment with insulin is yet unproved.

    In patients admitted for acute coronary syndrome (ACS), the guidelines of the European Society of Cardiology give a Class I, Level A recommendation for the prescription of high-intensity statins to be initiated as early as possible, regardless of the low-density lipoprotein cholesterol (LDL-C) level. Although statins are widely prescribed after ACS, the intensity of therapy and the proportion of patients achieving target LDL-C values are often not in line with recommendations due to a lack of compliance with guidelines by the physicians, a lack of compliance with treatment or poor tolerance by patients, and poor dose adaptation. In this context, a group of French physicians came together to define strategies to facilitate and improve the management of lipid-lowering therapy after ACS. This paper outlines the scientific rationale for the use of statins at the acute phase of ACS, the utility of ezetimibe, the measurement of LDL-C during the course of ACS, the opportunities for detecting familial hypercholesterolaemia and the results of the consensus for the management of lipid-lowering therapy, illustrated in two decision-making algorithms.

    Full Text Available BACKGROUND: Coronary artery disease (CAD is the major determinant of preoperative morbidity and mortality for patients requiring major vascular surgery. The management of CAD in these patients is controversial. AIMS: The incidence and severity of CAD in diabetic and non-diabetic patients with Leriche syndrome was explored. SETTINGS AND DESIGN: 107 patients with Leriche syndrome were selected as major vascular occlusion and grouped according to their diabetic Status. Sex, age, dyslipidemia, obesity, hypertension, clinic cardiac status, coronary angiographic lesions and coronary revascularisation procedures were noted. MATERIAL & METHODS: Patients′ demographics, intra-operative and per-operative data were recorded and compared. In every patient with Leriche syndrome scheduled for elective vascular reconstruction coronary angiography was performed. Lesions were evaluated for the percentages of stenosis. Preliminary coronary bypass or percutaneous coronary intervention was recommended for those found to have advanced or severe CAD. Results of revascularisation procedures were compared. STATISTICAL ANALYSIS USED: Chi-square or Fisher exact chi-square test is used for conditional variables. Independent samples was analysed by using t-test. Kruskal-Wallis variance test was used if the variances are not homogeneous according to the Levene test. RESULTS: No difference was found in both groups except family history and obesity. Coronary angiographic investigation indicates that 59% of DIAB group and 38% of NONDIAB group patients have advanced or severe CAD which has a high probability for myocardial revascularization. Overall revascularisation rate is 37.8% in DIAB group and 45.7% in NONDIAB group (p=0,641. Preoperative mortality was found 2.7% in diabetics and 4.2% in non-diabetics (p=0.342. CONCLUSIONS: Leriche syndrome with diabetes mellitus is more likely to have advanced coronary disease than those without diabetes mellitus. Coronary angiography

    Background Little is known about the impact of type 2 diabetes mellitus (DM) on coronary arteriole remodeling. The aim of this study was to determine the mechanisms that underlie coronary arteriole structural remodeling in type 2 diabetic (db/db) mice. Methods and Results Passive structural properties of septal coronary arterioles isolated from 12- and 16-wk-old diabetic db/db and control mice were assessed by pressure myography. Coronary arterioles from 12-wk-old db/db mice were structurally similar to age-matched controls. By 16-wks of age, coronary wall thickness was increased in db/db arterioles (p < 0.01), while luminal diameter was reduced (Control: 118±5μm; db/db: 102±4μm, p < 0.05), augmenting the wall-to-lumen ratio by 58% (Control: 5.9±0.6; db/db: 9.5±0.4, p < 0.001). Inward hypertrophic remodeling was accompanied by a 56% decrease in elastic modulus (p < 0.05, indicating decreased vessel coronary wall stiffness) and a ~30% reduction in coronary flow reserve in diabetic mice. Interestingly, aortic pulse wave velocity and femoral artery incremental modulus were increased (p < 0.05) in db/db mice, indicating macrovascular stiffness. Molecular tissue analysis revealed increased elastin-to-collagen ratio in diabetic coronaries when compared to control and a decrease in the same ratio in the diabetic aortas. Conclusions These data show that coronary arterioles isolated from type 2 diabetic mice undergo inward hypertrophic remodeling associated with decreased stiffness and increased elastin-to-collagen ratio which results in a decreased coronary flow reserve. This study suggests that coronary microvessels undergo a different pattern of remodeling from macrovessels in type 2 DM. PMID:21744279

    Conclusion: Syntax score has the ability to predict the occurrence of PMI with accepted sensitivity. It can assess the patient risk for development of PMI which could help to rationalize the use of adjunctive therapies as distal embolic protection devices in high risk patients. Also, diabetic patients have higher incidence of complicated coronary lesions, higher syntax score and they are more labile for PMI.

    Full Text Available Familial hypercholesterolemia is characterized by high serum levels of total cholesterol and LDL-cholesterol. It may be homozygous or heterozygous. In homozygous patients, LDL-cholesterol levels range from 500 to 1000mg/dL and coronary artery disease is precocious, usually manifesting itself between the 2nd and 3rd decades of life. The diagnosis is often made by the presence of xanthoma tuberosum and tendinous xanthomas that appear between the 1st and 2nd decades of life. The use of high doses of statins or even unusual procedures (apheresis, partial ileal bypass surgery, liver transplantation, gene therapy, or both, is necessary for increasing survival and improving quality of life, because a reduction in cholesterol levels is essential for stabilizing the coronary artery disease and reducing xanthomas. We report our experience with 3 patients with xanthomatous familial hypercholesterolemia and coronary artery disease, who underwent partial ileal bypass surgery. Their follow-up over the years (approximately 8 years showed a mean 30% reduction in total cholesterol, with a significant reduction in the xanthomas and stabilization of the coronary artery disease.

    This study aims to investigate whether preoperative L-carnitine supplementation affects the neutrophil-to-lymphocyte ratio (NLR) in patients undergoing coronary artery bypass grafting surgery. The neutrophil-to-lymphocyte ratio is an inflammatory marker that has proven usefulness for predicting postoperative complications in coronary artery bypass surgery. A lot of studies concerning the role of L-carnitine in the immune system have been performed, contradictory results have been reported on its effects on absolute numbers of WBC subtypes. This randomized, double-blinded, placebo-controlled study was conducted among patients scheduled for coronary artery bypass grafting surgery between June 2012 and December 2013 in our cardiovascular surgery clinic. A total of 60 consecutive patients were randomized and divided into 2 groups. The first group received 2 g of L-carnitine in 1000 mL of 0.9% saline solution infused over 24 hours for each of the 3 preoperative days (L-carnitine group, n = 30), or only 1000 mL of 0.9% saline solution for the same time period (placebo group, n = 30). The basal values of leukocyte, neutrophil, lymphocyte counts, and neutrophil to lymphocyte ratio were similar in the 2 groups. After L-carnitine supplementation (just before surgery), leukocyte and neutrophil counts of the L-carnitine group were significantly lower than those of the placebo group (7.7 ± 1.5 versus 9.7 ± 2.6, P carnitine group (1.1 ± 0.6 versus 0.8 ± 0.9, P carnitine group at postoperative day 1 (20.7 ± 13.8 versus 10.8 ± 4.1, P carnitine supplementation may reduce neutrophil-lymphocyte ratio during the early postoperative period of coronary artery bypass grafting surgery.

    Aim: This study aimed to compare the efficacy and safety between standard and low-dose tirofiban in the treatment of elderly high-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients who underwent percutaneous coronary intervention (PCI).Methods: Ninety-four very elderly (≥80 years) high-risk patients with NSTE-ACS were randomly assigned to the standard myocardial infarction (TIMI) grade flow were assessed. The major adverse cardiac events (MACEs), including death, myocardial infarction, recurrent angina and urgent target-vessel revascularization (TVR), were documented at 7 d, 30 d, and 6 months, and bleeding events were recorded at 7 d.Results: Although a significantly higher inhibition of platelet aggregation was observed in the standard-dose group (P0.05). The rate of MACEs was not significantly different at 7 days (2.1% vs 4.4%, P=0.61), 30 days(6.3% vs 8.7%, P=0.71) and 6 months (14.6% vs 17.4%, P=0.71). Major bleeding events were significantly higher in the standard-dose group (10.4% vs 0.0%, P=0.03).Conclusion: In very elderly high-risk patients with NSTE-ACS undergoing PCI, low-dose tirofiban offered about the same level of protection from major ischemic events that standard doses did, with less associated bleeding.

    A haemostatic technique that maintains radial artery flow ("patent haemostasis") following transradial catheterization reduces rates of radial artery occlusion (RAO) in patients with stable coronary disease. It is unclear whether this benefit extends to patients with an acute coronary syndrome (ACS). Patients undergoing inpatient transradial catheterization for an ACS were prospectively enrolled in a consecutive cohort study (n=300). Radial haemostasis was obtained using standard radial compression (cohort 1; n=150) or patent haemostasis (cohort 2; n=150). An end-of-case activated clotting time (ACT) was recorded and radial artery patency assessed within 24 hours of sheath removal by reverse Barbeau's test. The incidence of RAO was 16.0% following standard radial compression and 5.3% following patent haemostasis (p=0.003). Univariate predictors of RAO were patent haemostasis (OR 0.30; [0.13-0.68], p=0.004), hyperlipidaemia (OR 0.46; [0.21-0.98], p=0.04), history of current smoking (OR 2.86; [1.3-6.0], p=0.015) and longer procedure times (OR 1.03/additional minute; [1.01-1.05], p=0.003). There was no association between the end-of-case ACT and RAO (OR 1.00; [0.9-1.01] p=1.00). After adjusting for covariates, patent haemostasis reduced the risk of RAO by 70% compared to standard compression (OR 0.30; [0.12-0.77], p=0.12). The c-statistic for model discrimination was 0.79 (95% CI [0.71-0.86], ppatent haemostasis as an independent predictor of reduced RAO (OR 0.38 [0.15-0.95], p=0.039). Patent haemostasis is highly effective in preventing early RAO in patients with ACS. Copyright © 2017 Elsevier B.V. All rights reserved.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been...... defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease.

    The authors report two cases of acute coronary syndrome diagnosed by diastolic color kinesis imaging (CKI), an echocardiographic technique facilitating regional left ventricular wall motion analysis. Although both patients had experienced chest pain within the previous several days, the pain had remitted prior to visiting the clinic. In addition, neither electrocardiography nor routine echocardiography revealed ischemic changes. However, diastolic CKI clearly showed regional diastolic asynchrony of the left ventricle. Coronary angiography revealed significant stenosis compatible with the region of diastolic asynchrony observed on diastolic CKI. The patients underwent successful coronary revascularization, and diastolic asynchrony disappeared after revascularization. These findings suggest that diastolic CKI is useful for the diagnosis of acute coronary syndrome, even at rest and in the absence of chest pain.

    There is evidence that coronary collaterals improve the prognosis in patients with acute myocardial infarction (MI). However, there is limited clinical information on the protective role of collaterals in patients with stable coronary artery disease. This information may help risk stratification and the development of novel therapies, such as arteriogenesis and angiogenesis. The relation between collaterals and cardiac death or MI at 1 year after coronary revascularization was studied in 561 patients who were enrolled in a randomized study that compared stent implantation with bypass grafting. Collaterals were assessed on an angiogram using Rentrop's classification and considered present with a Rentrop grade >1. Unadjusted and adjusted odds ratios for cardiac death or MI at 1 year were calculated using univariate and multivariate regression analyses. In addition, determinants of collaterals were assessed using univariate and multivariate analyses. Collaterals were present in 176 patients (31%). The adjusted odds ratio of cardiac death or infarction was 0.18 (95% confidence interval 0.04 to 0.78) in the presence of collaterals. Independent determinants of collaterals were age (odds ratio 0.97, 95% confidence interval 0.95 to 0.99), multivessel disease (odds ratio 1.60, 95% confidence interval 1.02 to 2.51), impaired ventricular function (odds ratio 1.85, 95% confidence interval 1.04 to 3.29), type C lesion (odds ratio 3.72, 95% confidence interval 2.33 to 5.95), and stenosis severity >90% (odds ratio 9.08, 95% confidence interval 4.65 to 17.73). In conclusion, in patients with a low risk profile, the presence of collaterals protects against cardiac death and MI at 1 year after coronary revascularization. Variables that reflect the duration and severity of the atherosclerotic and ischemic burden determine their presence.

    To examine clinical characteristics, treatment and outcome of Kawasaki syndrome patients in Denmark. A retrospective chart review of hospitalization records for children Kawasaki syndrome discharge diagnosis identified through the Danish National Patient Registry during 1994 through June 2008 was conducted. A total of 284 cases Kawasaki syndrome (n = 279) and atypical Kawasaki syndrome (n = 5); 70.4% were Kawasaki syndrome patients were diagnosed with coronary artery abnormalities. Not receiving intravenous immunoglobulin treatment before the 10th day of illness, young age and male sex were significantly associated with the development of coronary artery abnormalities. In Denmark, more than one in 10 children with Kawasaki syndrome develop coronary artery abnormalities. Physicians should increase their index of suspicion for early diagnosis and treatment of Kawasaki syndrome among patients susceptible to increased risk of coronary artery abnormalities, particularly in infants who may have a more atypical presentation of the illness. ©2012 The Author(s)/Acta Paediatrica ©2013 Foundation Acta Paediatrica.

    Metabolic syndrome is associated with poor operative outcomes of coronary artery bypass grafting surgery (CABG). A healthy food pattern for metabolic syndrome patients is necessary not only in the initial stage to prevent cardiovascular disease but for those who experience cardiovascular problems and undergo heart surgery. Empirical studies that explore food pattern and quality of life metabolic syndrome patients who undergo CABG are lacking. Therefore, the objectives of this study are to explore the food pattern and quality of life of metabolic syndrome patients who undergo CABG and to examine the relationship between these two variables. A descriptive, correlational and cross section design was conducted. Through convenience sampling, 104 patients were recruited. Data were collected through three instruments: a demographic questionnaire; the Chinese Food Frequency Questionnaire-Short Form (Short C-FFQ), used to assess food pattern; and the Taiwanese version of the Medical Outcomes Study Short Form 36-Health Survey (SF-36), used to assess quality of life. Descriptive analysis, one-way analysis of variance (ANOVA) and Pearson correlation were used to analyze the data. The results indicated that patients who ate fruit more frequently tended to have a better quality of life, while the intake of fried food was more frequently associated with a poor quality of life. The use of these data gives the health care provider a better understanding of food pattern and their impact on quality of life in this population. Such an understanding can be used to develop targeted interventions to promote health in this and in other populations.

    Full Text Available Marvin Krohn-Grimberghe, Christoph Bode, Constantin von zur MuhlenDepartment of Cardiology and Angiology I, Heart Center, University of Freiburg, GermanyAbstract: Angioplasty and stent implantation have greatly improved the outcome of patients with acute coronary syndrome. However, stents come with the risk of stent thrombosis, which is associated with a high rate of revascularization, myocardial infarction, and death. The inhibition of factor Xa due to rivaroxaban leads to an interruption of the intrinsic as well as the extrinsic coagulation pathway, which reduces thrombus formation as a potential mechanism to diminish the rate of stent thrombosis. In this review, we evaluate the role of rivaroxaban in the prevention of stent thrombosis and its general role in patients with acute coronary syndrome.Keywords: Rivaroxaban, stent thrombosis, acute coronary syndrome, secondary prevention

    Background: Recovery from myocardial infarction has been associated with patients' perceptions of damage to their heart. New technologies offer a way to show patients animations that may foster more accurate perceptions and encourage medication adherence, increased exercise and faster return to activities. The purpose of this study was to investigate the effects of a brief animated intervention delivered at the patients' bedside on perceptions and recovery in acute coronary syndrome patients. Seventy acute coronary syndrome patients were randomly assigned to the intervention or standard care alone. Illness perceptions, medication beliefs and recovery outcomes were measured. Post-intervention, the intervention group had significantly increased treatment control perceptions and decreased medication harm beliefs and concerns. Seven weeks later, intervention participants had significantly increased treatment control and timeline beliefs, decreased symptoms, lower cardiac avoidance, greater exercise and faster return to normal activities compared to control patients. A brief animated intervention may be clinically effective for acute coronary syndrome patients (Trial-ID: ACTRN12614000440628).

    ESSENTIALS: The reliability of platelet tests as markers of the variable bioavailability of clopidogrel is not yet defined. Kinetics of clopidogrel active metabolite (CAM) and platelet response were studied in ischemic heart disease. CAM plasma maximum concentration (Cmax ) predicted vasodilator-stimulated phosphoprotein (VASP-P). Timely performed VASP-P, not an aggregation-based test, may be a surrogate for clopidogrel bioavailability. The high inter-individual variability in the inhibition of platelet function by clopidogrel is mostly explained by high variability in its transformation to an active metabolite (CAM). Objective We investigated the relations between pharmacokinetics and pharmacodynamics of CAM by comparing two methods of platelet function. We enrolled 14 patients undergoing percutaneous coronary interventions for non-ST-segment elevation acute coronary syndrome or inducible myocardial ischemia. Plasma concentrations of clopidogrel and CAM, phosphorylation of vasodilator-stimulated phosphoprotein (VASP-P), expressed as a platelet reactivity index (PRI) and whole-blood platelet aggregation (multiple electrode aggregometer, MEA) were measured before and after a 600-mg clopidogrel loading dose (nine time-points) and before and after 75-mg maintenance doses on days 2, 7 and 30. Plasma concentrations of clopidogrel and CAM were highly variable. CAM reached maximal concentration (Cmax ) (median, 110.8 nm; range, 41.9-484.8) 0.5-2 h after the loading dose. A sigmoid dose-response curve defined the relations between CAMCmax and PRI after 3 to 24 h (IC50 , 459.6 nm; 95% confidence interval, 453.4-465.7; R(2) = 0.82). PRI was unchanged from baseline in patients with the lowest CAMCmax (CAM pharmacokinetics at any time-point. After 600 mg clopidogrel, VASP-P, but not whole-blood platelet aggregation measured by MEA, is almost entirely predicted by CAMCmax . VASP-P could be useful in studies aimed at investigating relations between CAM bioavailability and

    Some studies of patients with acute myocardial infarction have reported that hyperglycaemia at admission may be associated with a worse outcome. This study sought to evaluate the association of blood glucose at admission with the outcome of unselected patients with acute coronary syndrome (ACS). Using the Acute Myocardial Infarction and unstable angina in Switzerland (AMIS Plus) registry, ACS patients were stratified according to their blood glucose on admission: group 1: 2.80-6.99 mmol/L, group 2: 7.00-11.09 mmol/L and group 3: > 11.10 mmol/L. Odds ratios for in-hospital mortality were calculated using logistic regression models. Of 2,786 patients, 73% were male and 21% were known to have diabetes. In-hospital mortality increased from 3% in group 1 to 7% in group 2 and to 15% in group 3. Higher glucose levels were associated with larger enzymatic infarct sizes (p<0.001) and had a weak negative correlation with angiographic or echographic left ventricular ejection fraction. High admission glycaemia in ACS patients remains a significant independent predictor of in-hospital mortality (adjusted OR 1.08; 95% confidence intervals [CI] 1.05-1.14, p<0.001) per mmol/L. The OR for in-hospital mortality was 1.04 (95% CI 0.99-1.1; p=0.140) per mmol/L for patients with diabetes but 1.21 (95% CI 112-1.30; p<0.001) per mmol/L for non-diabetic patients. In conclusion, elevated glucose level in ACS patients on admission is a significant independent predictor of in-hospital mortality and is even more important for patients who do not have known diabetes.

    Full Text Available David H FitchettDivision of Cardiology, Department of Medicine, St Michael's Hospital, University of Toronto, Toronto, Ontario, CanadaAbstract: Patients with acute coronary syndrome (ACS continue to be at risk for recurrent ischemic events, despite an early invasive strategy and the use of dual antiplatelet therapy. The anticoagulant pathway remains activated for a prolonged period after ACS and, consequently, has been a target for treatment. Early studies with warfarin indicated its benefit, but the risk of bleeding and the complexities of warfarin anticoagulation resulted in little use of this strategy. Rivaroxaban, apixaban, and dabigatran are new specific inhibitors of anticoagulant factors (Xa or IIa currently available for the prevention of thrombosis and/or thromboembolism. Thus far, studies with dabigatran and apixaban in ACS have shown no clinical benefit and bleeding has been increased. The ATLAS ACS 2-TIMI 51 trial observed the impact of rivaroxaban 2.5 mg and 5 mg twice daily in patients with recent ACS receiving current management (both early invasive strategy and dual antiplatelet therapy with aspirin and clopidogrel over a follow-up period of over 1 year. Rivaroxaban 2.5 mg twice daily reduced cardiovascular death, myocardial infarction, or stroke by 16%, and both cardiovascular and all-cause mortality by approximately 20%. Although major bleeding increased from 0.6% to 2.1% and intracranial hemorrhage from 0.2% to 0.6%, there was no increase in fatal bleeding. The role of rivaroxaban in the management of ACS is discussed in this review. The reduction in mortality is the main finding that could lead to the use of rivaroxaban in the management of ACS in high-risk individuals with a low bleeding risk.Keywords: cardiovascular death, myocardial infarction, stroke, anticoagulation, bleeding risk

    Owing to the heterogeneous population of patients with acute coronary syndromes (ACS), risk stratification with tools such as the GRACE risk score is recommended to guide therapeutic management and improve outcome. To evaluate whether anaemia refines the value of the GRACE risk model to predict midterm outcome after an ACS. A prospective registry of 1064 ACS patients (63 ± 14 years; 73% men; 57% ST-segment elevation myocardial infarction [MI]) was studied. Anaemia was defined as haemoglobin less than 13 mg/dL in men or less than 12 mg/dL in women. The primary endpoint was 6-month death or rehospitalization for MI. The primary endpoint was reached in 132 patients, including 68 deaths. Anaemia was associated with adverse clinical outcomes (hazard ratio 3.008, 95% confidence interval 2.137-4.234; PAnaemia provided additional prognostic information to the GRACE score as demonstrated by a systematic improvement in global model fit and discrimination (c-statistic increasing from 0.633 [0.571;0.696] to 0.697 [0.638;0.755]). Subsequently, adding anaemia to the GRACE score led to reclassification of 595 patients into different risk categories; 16.5% patients at low risk (≤ 5% risk of death or rehospitalization for MI) were upgraded to intermediate (>5-10%) or high risk (>10%); 79.5% patients at intermediate risk were reclassified as low (55%) or high risk (24%); and 45.5% patients at high risk were downgraded to intermediate risk. Overall, 174 patients were reclassified into a higher risk category (17.3%) and 421 into a lower risk category (41.9%). Anaemia provides independent additional prognostic information to the GRACE score. Combining anaemia with the GRACE score refines its predictive value, which often overestimates the risk.

Although the prevalencies of these two conditions are slightly high, most of them had not been treated well. The mechanisms that underly the association between depression and anxiety with the negative cardiovascular outcome are possibly correlates with their effect on inflammatory process, cathecolamine release, heart rate variability, endothelial function and also their effect on health promoting behavior. Fortunately, the standard therapies that available for these conditions are safe, effective, and can be tolerated well in most patients. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

Methods: Between January 2002 and May 2011, totally 1554 consecutive patients who experienced STEMI undergoing primary PCI were enrolled into the study. Results: Of the 1554 patients, 124 (9.7% with diagnosis of COPD and 1430 (90.3% without COPD were categorized into group 1 and group 2. Although no difference in in-hospital mortality was noted between the two groups (p = 0.726. However, the hospitalization duration was notably longer (p = 0.003, the incidences of recurrent MI and re-hospitalization for congestive heart failure were significantly higher in group 1 than in group 2 (all p < 0.02. Although Kaplan-Meier analysis demonstrated that the incidence of freedom from one-year major adverse clinical outcome (MACO (defined as recurrent MI, re-admission for congestive heart failure was significantly lower in group 1 than group 2 (p = 0.012, multivariate Cox regression analysis showed COPD was not an independent predictor of MACO-free time after adjusting traditional risk factors. Conclusion: COPD was not an independent predictor of short-term and medium-term MACO in patients with STEMI undergoing primary PCI.

    Abstract Invasive coronary angiography (ICA) is the recommended assessment for coronary artery disease in patients undergoing elective aortic valve replacement (AVR). Noncontrast computed tomography (CT) is useful for evaluating lung lesions and calcifications at the cannulation site of the ascending aorta. The purpose of this study was to evaluate the role of noncontrast CT in the visual assessment of coronary artery calcification (CAC) in patients undergoing AVR. We retrospectively identified patients with significant aortic stenosis (AS) who were referred for AVR between January 2006 and December 2013. Among these, we included 386 patients (53.6% males, 69.2 ± 8.4 years) who underwent both noncontrast CT and ICA. Significant coronary artery stenosis (CAS) in the ICA was defined as luminal stenosis ≥70%. The 4 main coronary arteries were visually assessed on noncontrast CT and were scored based on the Weston score as follows: 0, no visually detected calcium; 1, a single high-density pixel detected; 3, calcium was dense enough to create a blooming artifact; and 2, calcium in between 1 and 3. Four groups were reclassified by the sum of the Weston scores from each vessel, as follows: noncalcification (0); mild calcification (1–4); moderate calcification (5–8); and severe calcification (9–12). Receiver-operating characteristic (ROC) analysis was generated to identify the cutoff Weston score values for predicting significant CAS. Diagnostic estimates were calculated based on these cutoffs. In the ICA analysis, 62 of the 386 patients (16.1%) had significant CAS. All patients were divided into 4 groups. The noncalcification group had 97 subjects (Weston score 0), the mild degree group had 100 (2.6 ± 1.0), the moderate calcification group had 114 (6.6 ± 1.1), and the severe calcification group had 75 (10.7 ± 1.1). The prevalence of significant CAS in the noncalcification, mild, moderate, and severe groups was 1% (1/97), 5% (5/100), 24% (27

    The aim of this systematic literature review was to assess the consequences of dual antiplatelet therapy discontinuation on clinical outcomes after acute coronary syndromes. A systematic literature search was conducted in PubMed to identify studies reporting data on patients who discontinued dual antiplatelet therapy (planned or unplanned) following acute coronary syndromes and on the clinical impact of dual antiplatelet therapy discontinuation. To be included, more than 50% of the study population had to have had acute coronary syndrome as their index event or, if less than 50%, outcomes data must have been reported separately for the group with acute coronary syndromes. Thirty publications covering 29 studies were identified for inclusion. There was much heterogeneity across studies regarding the included patient populations, treatment durations and outcome definitions and ascertainments. Dual antiplatelet therapy discontinuation was most commonly based on physician decision. Twenty-six studies reported that clopidogrel was prescribed as part of dual antiplatelet therapy. Dual antiplatelet therapy duration was positively associated with a lower risk of all-cause mortality (seven/eight studies), cardiovascular mortality (two/two studies), non-fatal myocardial infarction (two/three studies) and stent thrombosis (five/five studies) in patients and/or patient subgroups in studies without randomised treatment designs, although such associations were not observed in the one study that randomly assigned patients to treatment (i.e. planned discontinuation). Results from our systematic literature review generally support the benefit of longer-term dual antiplatelet therapy after acute coronary syndromes; however, further research is needed to determine the optimal length of dual antiplatelet therapy in patients after acute coronary syndrome, ideally using prospective studies.

    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.

    Poor prognosis is strongly associated with Acute Coronary Syndrome (ACS) and, even though a number of treatment strategies are available, the incidence of subsequent serious complications after an acute event is still high. Statins are hypolipidemic factors and recent studies have demonstrated that they have a protective role during the process of atherogenesis and that they reduce mortality caused by cardiovascular diseases. This review tries to reveal the function of the statins as a component of the primary and secondary action of acute coronary syndrome and to describe the lifestyle changes that have the same effect as the use of statins.

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%.

    The physical and mental needs of patients with coronary heart disease are affected by both the disease and the heart surgery in different ways. Such diverse needs require different approaches. A continuous care model, which involves orientation, sensitization, control, and evaluation, may favorably influence patient outcomes following coronary artery bypass grafting (CABG). We were interested to ascertain whether a continuous care model might lead to improved quality of life, compared with a routine care model, in patients undergoing CABG. A total of 66 patients scheduled for CABG were identified and randomized to receive either continuous care (based on the continuous care model) or routine postoperative management for 2 months. The subjects' quality of life and its physical and mental dimensions were measured by the 12-item Short-Form Health Survey. Each dimension was scored between 0 and 100, and higher scores indicated better quality of life. One and 2 months after the intervention, the scores of quality of life and its two dimensions were significantly higher in the intervention group than in the control group (P care model can promote health-related quality of life in patients after CABG.

    Full Text Available Uncalibrated semi-invasive continous monitoring of cardiac index (CI has recently gained increasing interest. The aim of the present study was to compare the accuracy of CI determination based on arterial waveform analysis with transpulmonary thermodilution. Fifty patients scheduled for elective coronary surgery were studied after induction of anaesthesia and before and after cardiopulmonary bypass (CPB, respectively. Each patient was monitored with a central venous line, the PiCCO system, and the FloTrac/Vigileo-system. Measurements included CI derived by transpulmonary thermodilution and uncalibrated semi-invasive pulse contour analysis. Percentage changes of CI were calculated. There was a moderate, but significant correlation between pulse contour CI and thermodilution CI both before (2=0.72, <0.0001 and after (2=0.62, <0.0001 CPB, with a percentage error of 31% and 25%, respectively. Changes in pulse contour CI showed a significant correlation with changes in thermodilution CI both before (2=0.52, <0.0001 and after (2=0.67, <0.0001 CPB. Our findings demonstrated that uncalibrated semi-invasive monitoring system was able to reliably measure CI compared with transpulmonary thermodilution in patients undergoing elective coronary surgery. Furthermore, the semi-invasive monitoring device was able to track haemodynamic changes and trends.

    Reperfusion injury is a well-known phenomenon following restoration of the coronary circulation after coronary artery bypass grafting (CABG) that impairs myocardial function. In order to control the severity of this injury, we aimed to investigate the effect of a new conditioning strategy namely ischemic postconditioning (IPOC) along with controlled aortic root reperfusion (CARR) on myocardial protection in CABG surgery with cardiopulmonary bypass. In a doubled blind clinical trial study, 51 patients undergoing first-time elective CABG were randomly divided in three groups: CARR, IPOC, and combination of IPOC and CARR. At the end of procedure and just before aortic cross-clamp removal, reperfusion was started as following: In CARR-receiving groups, the reperfusion was started with low perfusion pressures for 10 minutes, and in IPOC-receiving groups, three cycles of 1 minute episodes of ischemia separated by 1 minute episodes of reperfusion was applied as postconditioning protocol. Left ventricular ejection fraction (EF) (by echocardiography), inotrope requirement index, and myocardial arrhythmias were measured up to 72 hours after operation. Echocardiography revealed that the recovery of EF after operation in IPOC group was significantly higher than those of two other groups (P < 0.05). Inotropic support requirement was significantly lower in IPOC groups. In addition, the incidence of atrial and ventricular arrhythmias after opening of aortic clamp and in intensive care unit (ICU) as well as recovery time of cardiac rhythm upon reperfusion were lowered by administration of IPOC, as compared with CARR group. The study suggests that IPOC may provide clinical benefits against reperfusion injury in patients undergoing CABG surgery and maintain the post ischemic left ventricular performance.

    Full Text Available Haemodynamic monitoring during exercise testing is seldom used during cardiac rehabilitation. The aim was to evaluate haemodynamic changes using the cardiac impedance method during exercise testing in patients after percutaneous coronary interventions and coronary artery bypass grafting during cardiac rehabilitation. Thirty (25 M; 5 F patients were included in the programme. The group was divided according to ejection fraction (EF: low – below 50% normal – equal to or above 50%. The exercise test was performed simultaneously with a four-electrode impedance cardiogram before and after rehabilitation. ECG, blood pressure, thoracic impedance, first derivative dz/dt, stroke volume (SV and cardiac output were recorded. Contractility index (Heather index – HI and vascular peripheral resistance were calculated. The pattern of haemodynamic changes was normal in 24 patients. The deflection points for HI and SV trend patterns were observed among patients with low EF. The contractility index decreased 90 s before maximal exercise and after the next 30-60 s a deflection point was observed in SV curve trends. In 24 patients with normal EF the contractility index trends did not decrease and SV trends increased until the end of exercise or a deflection point was not noted. The deflection points of the contractility index and SV curves were observed before the clinical indications for exercise test termination appeared in patients with a low ejection fraction. Impedance cardiography may indicate the threshold of the workload during real-time exercise testing.

    Background Percutaneous coronary intervention (PCI) is indicated for angina with coronary stenosis.However,PCI for asymptomatic coronary stenosis remains controversial.We prospectively followed a group of patients for four years who underwent coronary computed tomography angiography (CCTA) for major adverse cardiac events (MACE).We hypothesized that the results of this trial would reliably reflect the natural outcome of the coronary disease.Methods Consecutive patients who underwent CCTA from June 2008 to May 2009 were selected.Those who could not be reached by telephone,had significant angina,had CT images that were not interpretable,or poor kidney and left ventricular (LV) function were excluded.The patients were divided into five groups:group A normal CCTA without stenosis,group B mild stenosis (1%-49%),group C moderate stenosis (50%-74%),group D severe stenosis (≥75%) and they were treated with optimal medical therapy (OMT) or PCI.The group E had PCI before the CCTA examination.The patients were then followed for MACE after different treatments.MACE included acute myocardial infarction (MI),heart failure (HF) and death.Results The patient population consisted of 419 patients.The follow-up time was (51±5) months.The age was (60±31)years.Male made up 67.78% of the population (n=284).A total of 51 cases of MACE occurred including 25 MI,eight HF and 18 all-cause deaths.There was no MACE in group A.Although MACE occurred in two patients in group B,they were not attributed to cardiac death.We further compared the MACE in groups C-E and no significant difference was found (P >0.05).However,a difference was detected among patients with unstable angina pectoris (UAP),stable angina pectoris (SAP),re-hospitalization,and cerebrovascular events from groups A-E (P <0.05).The plaque scores were used to predict MACE.The scores progressively increased significantly with lesion severity (P <0.05).Receiver operating curve (ROC) was performed to determine the

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

    Background Among patients with coronary artery disease (CAD), 80%–90% present at least one conventional risk factor. On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS) has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50%) determined through coronary angiography is not well described. Methods We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown o n angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex. Results Most patients (81.7%) were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%), dyslipidemia (47.5%), and diabetes (37.7%). In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that 85.1% of patients had some type of dyslipidemia, and the most frequent was low levels of high-density lipoprotein cholesterol (68.6% of cases). Conclusion We found at least one conventional risk factor in 95.7% of patients with ACS and significant CAD. The lipid profile analysis revealed that two thirds of cases had low high-density lipoprotein cholesterol levels. PMID:25328397

    OBJECTIVE We examined the prevalence, extent, severity, and prognosis of coronary artery disease (CAD) in individuals with and without diabetes (DM) who are similar in CAD risk factors. RESEARCH DESIGN AND METHODS We identified 23,643 consecutive individuals without known CAD undergoing coronary computed tomography angiography. A total of 3,370 DM individuals were propensity matched in a 1-to-2 fashion to 6,740 unique non-DM individuals. CAD was defined as none, nonobstructive (1–49% stenosis), or obstructive (≥50% stenosis). All-cause mortality was assessed by risk-adjusted Cox proportional hazards models. RESULTS At a 2.2-year follow-up, 108 (3.2%) and 115 (1.7%) deaths occurred among DM and non-DM individuals, respectively. Compared with non-DM individuals, DM individuals possessed higher rates of obstructive CAD (37 vs. 27%) and lower rates of having normal arteries (28 vs. 36%) (P < 0.0001). CAD extent was higher for DM versus non-DM individuals for obstructive one-vessel disease (19 vs. 14%), two-vessel disease (9 vs. 7%), and three-vessel disease (9 vs. 5%) (P < 0.0001 for comparison), with higher per-segment stenosis in the proximal and mid-segments of every coronary artery (P < 0.001 for all). Compared with non-DM individuals with no CAD, risk of mortality for DM individuals was higher for those with no CAD (hazard ratio 3.63 [95% CI 1.67–7.91]; P = 0.001), nonobstructive CAD (5.25 [2.56–10.8]; P < 0.001), one-vessel disease (6.39 [2.98–13.7]; P < 0.0001), two-vessel disease (12.33 [5.622–27.1]; P < 0.0001), and three-vessel disease (13.25 [6.15–28.6]; P < 0.0001). CONCLUSIONS Compared with matched non-DM individuals, DM individuals possess higher prevalence, extent, and severity of CAD. At comparable levels of CAD, DM individuals experience higher risk of mortality compared with non-DM individuals. PMID:22699296

    ABSTRACT Objective: To evaluate the use of hyperbaric oxygen therapy as an adjunctive treatment in mediastinitis after coronary artery bypass surgery. Methods: This is a retrospective descriptive study, performed between October 2010 and February 2012. Hyperbaric oxygen therapy was indicated in difficult clinical management cases despite antibiotic therapy. Results: We identified 18 patients with mediastinitis during the study period. Thirty three microorganisms were isolated, and polymicrobial infection was present in 11 cases. Enterobacteriaceae were the most prevalent pathogens and six were multi-resistant agents. There was only 1 hospital death, 7 months after the oxygen therapy caused by sepsis, unrelated to hyperbaric oxygen therapy. This treatment was well-tolerated. Conclusion: The initial data showed favorable clinical outcomes. PMID:24136762

    Reiki was administered to 50 patients out of 100 patients with normal left ventricular function scheduled for elective coronary artery bypass grafting. Blood components and inflammatory markers were estimated at various time points. Haemodynamic parameters, psychological analysis, intensive care unit stay,incidence of infection, chest tube drainage and mortality were recorded. Haemodynamic parameters and use of blood components were similar in both groups. Interleukin-6 were significantly lower in the preoperative period in the Reiki group, but showed similar trends in both the groups in the post-operative period. The psychological analysis assessed by World Health Organisation quality of life and General Health Questionnaire revealed that social relationships improve once patient is in his own surroundings and with his own people in both the groups. Psychological domain showed significant difference, six day after surgery in the Reiki group. This study concludes that Reiki is a time consuming process with no significant clinical benefit.

    To establish whether plasma cytochrome c is detectable in patients undergoing cardiac surgery, whether cytochrome c levels are associated with lactate/inflammatory markers/cellular oxygen consumption, and whether cytochrome c levels are associated with clinical outcomes. This was an observational sub-study of a randomized trial comparing thiamine to placebo in patients undergoing coronary artery bypass grafting. Patients had blood drawn before, after, and again 6h after surgery. Cytochrome c, inflammatory markers, and cellular oxygen consumption were measured. 64 patients were included. Cytochrome c was detectable in 63 (98%) patients at baseline with a median cytochrome c level of 0.18ng/mL (quartiles: 0.13, 0.55). There was no difference from baseline level to post-surgical level (0.19ng/mL [0.09, 0.51], p=0.36) or between post-surgical level and 6-hour post-surgical level (0.17ng/mL [0.10, 0.57], p=0.61). There was no difference between the thiamine and placebo groups' change in cytochrome c levels from baseline to after surgery (p=0.22). Cytochrome c levels were not associated with lactate, inflammatory markers, cellular oxygen consumption, or clinical outcomes. Cytochrome c levels did not increase after cardiac surgery and was not associated with the degree of inflammation or clinical outcomes. Copyright © 2017. Published by Elsevier Inc.

    Coronary artery bypass grafting (CABG) still plays a fundamental role in the management of acute coronary syndromes. The aim of this study is to report the experience of our center in the treatment of patients with acute coronary sindromes without persistent ST elevation urgently operated on with CABG, and to discuss surgical problems related. Two-hundred and six patients were urgently operated on for CABG for acute coronary syndromes without persistent ST-segment elevation from January 2001 to February 2003. The majority of them had three vessel coronary disease (72%) and left main stem disease occurred in 20% of the patients. Mean LVEF (left ventricular ejection fraction) was 54 +/- 12% whereas 9% of the patients had a LVEF < 40%. Twenty-one patients (10%) received glycoprotein IIb/IIIa receptor inhibitors and 35 (17%) received intravenous heparin therapy before surgery. Mean interval time between the onset of symptoms and surgery was 16 +/- 10 days (range 4-50). In-hospital mortality was 2% (4 patients). Perioperative AMI (acute myocardial infarction) occurred in 4% (8 patients) and a transient low cardiac output syndrome in 27 patients (13%). Bleeding requiring surgery occurred in 1% of the patients. Transient respiratory insufficiency was present in 12 patients (6%) and acute renal failure in 8 patients (4%). Mean I.C.U. time was 2.4 days (1-17). Urgent CABG for acute coronary syndromes shows a low risk for in-hospital mortality and morbidity. In acute patients arterial grafts are not detrimental for the outcome, but are recommended in the absence of contraindications to improve long-term results. In spite of recent developments in cardioplegic cardiac arrest, optimal myocardial protection against perioperative myocardial infarction still remains a challenge.

    Full Text Available Introduction: Sleep is one of the basic human needs and sleep deprivation causes nu-merous adverse effects on the human body and mind. Due to reduced sleep quality in patients with acute coronary syndrome, this study was carried out to determine the effect of eye mask on sleep quality in patients with acute coronary syndrome. Methods: In this two-group controlled clinical trial, sixty patients with acute coronary syndrome in the coronary care units of Baqiyatallah Hospital in Tehran in 2010 were selected by pur-poseful sampling method and randomly allocated to two groups of case and control. In the case group, in the second night stay, the intervention of eye mask was done per night and by using the Petersburg's sleep quality index; sleep quality was evaluated during and at the end of hospitalization. Then data were analyzed by paired t-test, independent t-test, Spearman and Pearson's correlation coefficient and SPSS software version 19. Results: Total sleep quality score of the case group was significantly decreased after intervention (4.86 ± 1.88 from before intervention (10.46 ± 4.09 (p < 0.000. In addi-tion, total score of sleep quality after intervention in the case group (4.86 ± 1.88 was significant different from the control group (8.43 ± 1.97 (p < 0.005. Conclusion: Using eye mask, as an economical and uncomplicated method, can improve sleep quality in pa-tients with acute coronary syndrome in the coronary care units and can be used as an alter-native method of treatment instead of drug therapy.

    The aim of this study was to examine the impact of a brief psychoeducation group intervention on fear and anxiety in patients undergoing the coronary artery bypass grafting (CABG). Sixty consecutive patients undergoing CABG for the first time were recruited for a clinical trial and randomized into two groups. The control group received routine care. The study group received a brief psychoeducation group intervention combined with routine care. The psychoeducation session consisted of a discussion of fear and anxiety in a psychotherapeutic atmosphere and relaxation techniques. Fear was scored with the Bypass Grafting Fear Scale (BGFS) and anxiety was scored with the Spielberger State Inventory (STAI) Questionnaire. The BGFS and the STAI were given to the patients the day after hospital admission and a day before the operation to measure fear and anxiety. Fear scores decreased in the psychoeducation group. Of the 29 patients treated with psychoeducation, the mean (SD) fear score decreased from 4.6 (1.7) at baseline to 2.8 (1.2) before the operation (p  .05). The mean difference in fear score before the operation was significantly lower in the psychoeducation group than the routine care group (mean difference -1.3; 95% CI, -2.1, -.2; p anxiety scores before the operation between the psychoeducation and routine care groups. In patients undergoing CABG, adding psychoeducation to routine care had a significant positive effect on fear but not on anxiety scores. A larger study of psychoeducation in these patients is warranted to assess the efficacy of this intervention in greater detail.

    Objectives: This study sought to identify clinical and procedural predictors of elevated radiation dose received by patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) and to determine if elevated radiation dose was predictive of mortality in this population. Background: Little data exist regarding the impact of excessive radiation burden on clinical outcomes in patients undergoing PCI. Methods: The study population included 1,039 patients who underwent PCI for an AMI between January 1, 2007 and December 31, 2008 at an academic tertiary care teaching hospital. Cumulative skin dose (measured in milligray [mGy]) was selected as a measurement of patient radiation burden. Clinical and procedural variables were analyzed in multiple logistic and linear regression models to determine predictors of higher skin dose, and its impact was evaluated on all-cause intermediate-term mortality at two years. Results: Median skin dose was 2120 mGy (IQR 1379–3190 mGy) in the overall population, of which 153 (20.8%) patients received an elevated skin dose (defined as a skin dose > 4,000 mGy). Independent predictors of elevated skin dose included male gender, obesity, multivessel intervention, and presentation with a non-ST-elevation MI (NSTEMI) versus an ST-elevation MI (STEMI). Increased skin dose was not predictive of intermediate-term mortality by multivariate analysis in the overall population or in either subgroup of STEMI and NSTEMI. Conclusions: In this contemporary observational study examining patients with AMI undergoing PCI, male gender, obesity, multivessel intervention, and presentation with a NSTEMI were associated with increased radiation exposure.

    Patients undergoing coronary artery bypass graft (CABG) procedures have higher incidence of difficult laryngoscopy and intubation than general surgery population. Accurate prediction of difficult laryngoscopy in CABG patients is desirable to reduce the hemodynamic response and myocardial oxygen requirements. Recently, thyromental height test (TMHT) has been proposed as one of the highly sensitive and specific bedside tests to predict difficult airway. We, in our prospective observational study, evaluated the accuracy of the TMHT in predicting difficult laryngoscopy. A total of 345 patients undergoing CABG of either sex, in the age group of 35-80 years, American Society of Anesthesiologists 111, undergoing CABG, were studied. Airway assessment was performed with modified Mallampati test with the addition of thyromental distance, sternomental distance, and TMHT. Intraoperatively, direct laryngoscopy was done in accordance with Cormack and Lehane grade of laryngoscopy. The preoperative data and laryngoscopic findings were used together to evaluate the accuracy of TMHT. The sensitivity, specificity, positive and negative predictive values of other three tests were calculated according to standard formula. A total of 345 patients were in the group with mean age of study population at 56.7 (standard deviation 9.1) years (35-80 years). This study showed that almost all tests had good specificity, but sensitivity was poor. However, sensitivity of TMHT was 75% with accuracy of 95%. Receiver operating characteristic curve analysis of TMHT-derived cutoff was 52.17 which increased sensitivity to 81.25% and specificity to 92.3%. TMHT had a higher sensitivity compared to other tests along with good positive and negative predictive value and a very high specificity.

    Full Text Available Background: Open heart surgery is associated with severe postoperative pain due to the incision of chest wall anatomical components. Cryotherapy is a simple, cost-efficient, non-pharmacological method of pain relief. This study aimed to evaluate the effects of localized cryotherapy on the severity of thoracic pain in patients undergoing coronary artery bypass grafting (CABG. Methods: This clinical trial was conducted on 50 patients undergoing CABG in a teaching hospital in Zahedan, Iran in 2015. Patients were selected via convenience sampling and randomly allocated to two groups of intervention and control (n=25. Initially, postoperative pain was measured after three cycles of deep breathing and coughing using the visual analogue scale (VAS. In the intervention group, ice packs were placed on the chest wound dressing of the patients at five-minute intervals for 20 minutes. Afterwards, both groups received emotional support for 15 minutes, and pain scores were measured again. Data analysis was performed in SPSS version 21 using Chi-square, independent and paired t-test, and analysis of covariance (ANCOVA. Results: Mean pain scores before the intervention in the intervention and control groups were 60.16±13.45 and 58.64±14.42, respectively. After localized cryotherapy, these values were 45.16±15.25 in the intervention group and 58.60±14.40 in the control group (P<0.001. Conclusion: According to the results of this study, localized cryotherapy could reduce the severity of thoracic pain caused by coughing and deep breathing in patients undergoing CABG. Therefore, this method is recommended as a non-pharmacological method for pain relief.

    Full Text Available Objective. The aim of this study was to investigate the association between COPD and major adverse cardiovascular and cerebral events (MACCE in patients undergoing percutaneous coronary intervention (PCI. Methods. 2,362 patients who underwent PCI were included in this study. Subjects were divided into 2 groups: with COPD (n=233 and without COPD (n = 2,129. Cox proportional hazards models were analyzed to determine the effect of COPD on the incidence of MACCE. Results. The patients with COPD were older (P<0.0001 and were more likely to be current smokers (P=0.02 and have had hypertension (P=0.02 and diabetes mellitus (P=0.01. Prevalence of serious cardiovascular comorbidity was higher in the patients with COPD, including a history of MI (P=0.02 and HF (P<0.0001. Compared with non-COPD group, the COPD group showed a higher risk of all-cause death (hazard ratio (HR: 2.45, P<0.0001, cardiac death (HR: 2.53, P=0.0002, MI (HR: 1.387, P=0.027, and HF (HR: 2.25, P<0.0001. Conclusions. Patients with CAD and concomitant COPD are associated with a higher incidence of MACCE (all-cause death, cardiac death, MI, and HF compared to patients without COPD. The patients with a history of COPD have higher in-hospital and long-term mortality rates than those without COPD after PCI.

    Background This study assessed the risk of developing acute coronary syndrome requiring hospitalization in association with the use of certain antipsychotic medications in schizophrenia patients. Methods A nationwide cohort of 31,177 inpatients with schizophrenia between the ages of 18 and 65 years whose records were enrolled in the National Health Insurance Research Database in Taiwan from 2000 to 2008 and were studied after encrypting the identifications. Cases (n = 147) were patients with subsequent acute coronary syndrome requiring hospitalization after their first psychiatric admission. Based on a nested case-control design, each case was matched with 20 controls for age, sex and the year of first psychiatric admission using risk-set sampling. The effects of antipsychotic agents on the development of acute coronary syndrome were assessed using multiple conditional logistic regression and sensitivity analyses to confirm any association. Results We found that current use of aripiprazole (adjusted risk ratio [RR] = 3.68, 95% CI: 1.27–10.64, p<0.05) and chlorpromazine (adjusted RR = 2.96, 95% CI: 1.40–6.24, p<0.001) were associated with a dose-dependent increase in the risk of developing acute coronary syndrome. Although haloperidol was associated with an increased risk (adjusted RR = 2.03, 95% CI: 1.20–3.44, p<0.01), there was no clear dose-dependent relationship. These three antipsychotic agents were also associated with an increased risk in the first 30 days of use, and the risk decreased as the duration of therapy increased. Sensitivity analyses using propensity score-adjusted modeling showed that the results were similar to those of multiple regression analysis. Conclusions Patients with schizophrenia who received aripiprazole, chlorpromazine, or haloperidol could have a potentially elevated risk of developing acute coronary syndrome, particularly at the start of therapy.

    We conducted a small pilot observational study of the effects of bilateral thoracic paravertebral block (BTPB) as an adjunct to perioperative analgesia in coronary artery bypass surgery patients. The initial ropivacaine dose prior to induction of general anaesthesia was 3 mg/kg, which was followed at the end of the surgery by infusion of ropivacaine 0.25% 0.1 ml/kg/hour on each side (e.g. total 35 mg/hour for a 70 kg person). The BTPB did not eliminate the need for supplemental opioids after CABG in the eight patients studied. Moreover, in spite of boluses that were within the manufacturer's recommendation for epidural and major nerve blocks, and an infusion rate that was only slightly higher than what appeared to be safe for epidural infusion, potentially toxic total plasma ropivacaine concentrations were common. We also could not exclude the possibility that the high ropivacaine concentrations were contributing to postoperative mental state changes in the postoperative period. Also, one patient developed local anaesthetic toxicity after the bilateral paravertebral dose. As a result, the study was terminated early after four days. The question of whether paravertebral block confers benefits in cardiac surgery remains unanswered. However, we believe that the bolus dosage and the injection rate we used for BTPB were both too high, and caution other clinicians against the use of these doses. Future studies on the use of BTPB in cardiac surgery patients should include reduced ropivacaine doses injected over longer periods.

    The coronary slow flow phenomenon (CSFP) is an angiographic finding that is characterised by delayed progression of the contrast medium during coronary angiography. The mechanism of this phenomenon remains unknown. In the present paper, we revise the current evidence regarding this phenomenon and discuss recent findings from our group reporting increased resting resistances in patients with the CSFP. We report that these patients had preserved blood flow responses to the intracoronary infusion of the vasodilator papaverine, demonstrating that the CSFP is not necessarily associated with an abnormal coronary flow reserve. Based on these findings and on the review of the current literature, we concur with the concept proposed by Beltrame et al. that the CSFP should be considered a separate clinical entity. Further studies are necessary to describe the clinical characteristics, including the prognosis, of these patients and to identify potential treatments.

    We aimed to investigate the usefulness of monocyte to HDL cholesterol ratio (MHR) in predicting coronary artery disease severity and future major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). 2661 patient with ACS were enrolled and followed up during median 31.6 months. MHR were significantly positively correlated with neutrophil to lymphocyte ratio (r=0.438), CRP (r=0.394), Gensini (r=0.407), and SYNTAX score (r=0.333). During in-hospital and long-term follow-up, MACE, stent thrombosis, non-fatal MI, and mortality occurred more frequently in the third tertile group. Kaplan-Meier analysis revealed the higher occurrence of MACE in the third tertile group compared with other tertiles. Adjusting for other factors, a MHR value in the third tertile group was determined as an independent predictor of in-hospital and long-term MACE. MHR as a novel inflammation-based marker seemed to be an independent predictor of severity of coronary artery disease and future cardiovascular events in patients with ACS. MHR may utilise the identification of patients who are at higher risk for MACE and individualisation of targeted therapy.

    Myonecrosis after coronary artery bypass graft (CABG) surgery is associated with excess mortality. Tranexamic acid (TA), an anti-fibrinolytic agent, has been shown to reduce peri-operative blood loss without increasing the risk of myocardial infarction (MI); however, no large study has examined the association between TA treatment and post-CABG myonecrosis. In the MC-1 to Eliminate Necrosis and Damage in Coronary Artery Bypass Graft Surgery II trial, inverse probability weighting of the propensity to receive TA was used to test for differences among the 656 patients receiving and 770 patients not receiving TA. The primary outcome was creatine kinase MB (CK-MB) area under the curve (AUC) through 24 h. The secondary outcome was 30-day cardiovascular death or MI. Patients who received TA were more frequently female, had a previous MI, heart failure, low molecular weight heparin therapy, on-pump CABG, valvular surgery, and saphenous vein or radial grafts. The median 24-h CK-MB AUC was higher in TA-treated patients [301.9 (IQR 196.7-495.6) vs 253.5 (153.4-432.5) ng h/mL, p < 0.001]. No differences in the 30-day incidence of cardiovascular death or MI were observed (8.7 vs 8.3%, adjusted OR 0.99; 95% CI 0.67-1.45, p = 0.948). In patients undergoing CABG, TA use was associated with a higher risk of myonecrosis; however, no differences were observed in death or MI. Future larger studies should be directed at examining the pathophysiology of TA myonecrosis, and its association with subsequent clinical outcomes.

    Full Text Available Abstract Poland Syndrome is a congenital disorder characterised by hypoplasia of the pectoral muscles along with upper extremity deformities. We encountered a patient with Poland syndrome associated with dextrocardia and also failed pectus excavatum repairs who presented to us with symptomatic ischaemic heart disease requiring intervention. He underwent successful off-pump coronary artery bypass surgery (OPCABG. As far as we are aware, this is the first case report of OPCABG in a case of Poland syndrome with dextrocardia. We describe here the management of this complex patient and wish to emphasise that the off-pump option is feasible in dextrocardia with some technical modifications.

    Currently we know not more than 50 patients who show an interesting combination of increased plasma ornithine concentrations, postprandial hyperammonemia, and homocitrullinuria (HHH-syndrome). Since exact knowledge of this severe, although rare syndrome is important for any perioperative or intensive medical treatment concerning therapy and progression of the disease, we report a comprehensive study on a 32-year old woman with this rare multifaceted disorder who had to undergo general anaesthesia. For the first time amino acid status in plasma, urine, cerebrospinal fluid and especially polymorphonuclear leucocytes, which in the investigation showed to be valuable tool for evaluating amino acid metabolism in nucleated cells in HHH-syndrome, and further important pathophysiologic indicators of cellular and metabolic function have been conscientiously investigated and compared. The pathophysiological repercussions of our results as well as the recommendations for conscientious therapeutical management are discussed.

    Recently, monocyte-to-high density lipoprotein ratio (MHR) has been proposed as a novel prognostic indicator of cardiovascular diseases. However, no study is currently available regarding the comparison between MHR and monocyte count (MC) in predicting the outcomes among patients undergoing coronary angiography. A total of 3798 patients scheduled for selective coronary angiography were enrolled and followed up to capture major adverse cardiovascular events (MACEs, death, acute myocardial infarction, unstable angina, stroke, heart failure, and unexpected coronary revascularization). Cox proportional hazards models were used to evaluate the risk of MHR or MC on MACEs. During a median of 24.6 months follow-up, 347 (9.1%) MACEs occurred. The upper tertiles of MC and MHR have a significant lower event-free survival (p = 0.011; p = 0.014, respectively). Significantly, both MC and MHR were associated with increased MACEs risk after adjusting for potential confounders [adjusted HR (95% CI): 2.734 (1.547-4.832); 2.031 (1.268-3.254), respectively]. Additionally, the area under the receiver-operating characteristic curves of MC or MHR in predicting MACEs were 0.574 (0.542-0.606) and 0.562 (0.530-0.594) (p MHR was an independent predictor of MACEs whereas the prognostic impact was not superior to MC in patients who underwent coronary angiography. Key Messages MHR has been suggested as a novel prognostic indicator of several cardiovascular diseases. No study is currently available regarding the comparison of MHR to MC in predicting the outcomes in a large cohort of patients undergoing coronary angiography. Our data firstly indicate that MHR is independently associated with MACEs in patients undergoing coronary angiography whereas the prognostic impact is similar to MC.

    Background To examine the performance of coronary artery calcification (CAC) for stratifying long-term risk of death in asymptomatic hypertensive patients. Methods and Results 8905 consecutive asymptomatic individuals without cardiovascular disease or diabetes who underwent CAC testing (mean age 53.3±10.5, 59.3% male) were followed for a mean of 14 years and categorized on the background of hypertension (in accordance with the 2014 Guidelines from the Joint National Committee 8) as well as age above or below 60 years. The prevalence and severity of CAC was higher for those with versus without hypertension (P<0.001), and the extent increased proportionally with advancing age (P<0.001). Following adjustment, the presence of CAC in patients above and below the age of 60 years was associated with worse prognosis for hypertensive (HR 7.74 [95% CI: 5.15-11.63] and HR 3.18 [95% CI: 2.42-4.19]) and normotensive (HR 4.83 [95% CI: 3.18-7.33] and HR 2.14 [95% CI: 1.61-2.85]), respectively. A zero CAC score was associated with a lower but persisting risk of mortality for hypertensives over the age of 60 years (HR 2.48 [95% CI: 1.50-4.08]); albeit, attenuating for those below the age of 60 years (P=0.09). In a “low risk” hypertensive population, a combined presence of hypertension and any CAC was associated with an almost five-fold (HR 4.68 [95% CI: 2.22-9.87]) risk of death. Conclusion Among asymptomatic hypertensive individuals, the presence and extent of CAC effectively identified individuals at heightened risk of mortality beyond conventional cardiovascular risk.

    Controlling cardiovascular risk factors (CVRF) is important for the outcome of interventional practices (percutaneous coronary intervention [PCI]) in ischemic heart disease. The aim is to determine the evolution of the CVRF 6 months after the intervention and their relationship with new events. A descriptive study was conducted on a case series. The variables recorded were: age, sex and chronic kidney disease (CKD), as well as total (TC) and HDL cholesterol, systolic (SBP) and diastolic blood pressure (DBP), smoking habit, and body mass index (BMI), before PCI and after 6 months. The occurrence of death or new PCI during the follow-up was considered an independent variable in a logistic regression analysis. A P<.05 was assumed significant. A total of 222 cases (75.2% males) were included, with a mean age of 70.2 (SD 11.9) years, of whom 57.7% were hypertensive patients, 55.9% had hyperlipidemia, 50.4% were smokers or ex-smokers, and 28.2% were diabetics. After 6 months, 5% died, and 15.3% needed a new PCI, while 33% of the sample had all the CVRF considered. Decreases were observed in SBP (-3.3 mmHg), DBP (-2.6 mmHg), and TC (-35.2mg/dl). The emergence of new event was associated with age (OR: 1.06; P=.003) and CKD (OR: 3.7; P=.04). There is a high prevalence of CVRF. After 6 months, there was a decrease in blood pressure and TC, although incomplete control of CVRF was found. One fifth of the patients had an event in that period, showing association with age and CKD. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    Full Text Available Background: There has been a constant emphasis on developing management strategies to improve the outcome of high-risk cardiac patients undergoing surgical revascularization. The performance of coronary artery bypass surgery on an off-pump coronary artery bypass (OPCAB avoids the risks associated with extra-corporeal circulation. The preliminary results of goal-directed therapy (GDT for hemodynamic management of high-risk cardiac surgical patients are encouraging. The present study was conducted to study the outcome benefits with the combined use of GDT with OPCAB as compared to the conventional hemodynamic management. Material and Method: Patients with the European System for Cardiac Operative Risk Evaluation ≥3 scheduled for OPCAB were randomly divided into two groups; the control and GDT groups. The GDT group included the monitoring and optimization of advanced parameters, including cardiac index (CI, systemic vascular resistance index, oxygen delivery index, stroke volume variation; continuous central venous oxygen saturation (ScVO 2 , global end-diastolic volume, and extravascular lung water (EVLW, using FloTrac™ , PreSep™ , and EV-1000 ® monitoring panels, in addition to the conventional hemodynamic management in the control group. The hemodynamic parameters were continuously monitored for 48 h in Intensive Care Unit (ICU and corrected according to GDT protocol. A total of 163 patients consented for the study. Result: Seventy-five patients were assigned to the GDT group and 88 patients were in the control group. In view of 9 exclusions from the GDT group and 12 exclusions from control group, 66 patients in the GDT group and 76 patients in control group completed the study. Conclusion: The length of stay in hospital (LOS-H (7.42 ± 1.48 vs. 5.61 ± 1.11 days, P < 0.001 and ICU stay (4.2 ± 0.82 vs. 2.53 ± 0.56 days, P < 0.001 were significantly lower in the GDT group as compared to control group.

    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.

    Objectives This study sought to determine if there is an association between bleed location and clinical outcomes in acute coronary syndromes (ACS) patients. Background The prognostic significance of bleeding location among ACS patients undergoing cardiac catheterization is not well known. Methods We analyzed in-hospital bleeding events among 9,978 patients randomized in the SYNERGY (Superior Yield of the New Strategy of Enoxaparin, Revascularization, and Glycoprotein IIb/IIIa Inhibitors) study. Bleeding events were categorized by location as access site, systemic, surgical, or superficial, and severity was graded using the GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definition. We assessed the association of each bleeding location and severity with 6-month risk of death or myocardial infarction using a multicovariate-adjusted Cox proportional hazard model. Results A total of 4,900 bleeding events were identified among 3,694 ACS patients with in-hospital bleeding. Among 4,679 GUSTO mild/moderate bleeding events, only surgical and systemic bleeds were associated with an increased risk of 6-month death or myocardial infarction (adjusted hazard ratio [HR]: 2.52 [95% confidence interval (CI): 2.16 to 2.94, and 1.40 [95% CI: 1.16 to 1.69], respectively). Mild/moderate superficial and access-site bleeds were not associated with downstream risk (adjusted HR: 1.17 [95% CI: 0.97 to 1.40], and 0.96 [95% CI: 0.82 to 1.12], respectively). Among 221 GUSTO severe bleeds, surgical bleeds were associated with the highest risk (HR: 5.27 [95% CI: 3.80 to 7.29]), followed by systemic (HR: 4.48 [95% CI: 2.98 to 6.72]), and finally access-site bleeds (HR: 3.57 [95% CI: 2.35 to 5.40]). Conclusions Among ACS patients who develop in-hospital bleeding, systemic and surgical bleeding are associated with the highest risks of adverse outcomes regardless of bleeding severity. Although the most frequent among bleeds, GUSTO mild/moderate access-site bleeding is not

    Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patient’s prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. Material and Methods. A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort. Demographic and anamnestic data, clinical characteristics on admission, biochemical analysis of blood parameters on admission, and left ventricular ejection fraction formed the basis of the study. A number of machine learning algorithms available within Waikato Environment for Knowledge Discovery had been evaluated and the most successful was chosen. The predictive model was subsequently validated in a different population of 931 patients (validation cohort, hospitalized during 2012. Results. The best prediction results were achieved using Alternating Decision Tree classifier, which was able to predict in-hospital mortality with 89% accuracy, and preserved good performance on validation cohort with 87% accuracy. Alternating Decision Tree classifier identified a subset of 6 attributes most relevant to mortality prediction: systolic and diastolic blood pressure, heart rate, left ventricular ejection fraction, age, and troponin value. Conclusion. Data mining approach enabled the authors to develop a model capable of predicting the in-hospital outcome following percutaneous coronary intervention. The model showed excellent sensitivity and specificity during internal validation.

    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.

    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

    Objectives To determine whether the risk of cardiovascular mortality associated with cardiorenal syndrome subtype 1 (CRS1) in patients who were hospitalized for acute coronary syndrome (ACS) was greater than the expected risk based on the sum of its components, to estimate the predictive value of CRS1, and to determine whether the severity of CRS1 worsens the prognosis. Methods Follow-up study of 1912 incident cases of ACS for 1 year after discharge. Cox regression models were estimated with time to event (in-hospital death, and readmission or death during the first year after discharge) as the dependent variable. Results The incidence of CRS1 was 9.2/1000 person-days of hospitalization (95% CI = 8.1–10.5), but these patients accounted for 56.6% (95% CI = 47.4–65.) of all mortality. The positive predictive value of CRS1 was 29.6% (95% CI = 23.9–36.0) for in-hospital death, and 51.4% (95% CI = 44.8–58.0) for readmission or death after discharge. The risk of in-hospital death from CRS1 (RR = 18.3; 95% CI = 6.3–53.2) was greater than the sum of risks associated with either acute heart failure (RR = 7.6; 95% CI = 1.8–31.8) or acute kidney injury (RR = 2.8; 95% CI = 0.9–8.8). The risk of events associated with CRS1 also increased with syndrome severity, reaching a RR of 10.6 (95% CI = 6.2–18.1) for in-hospital death at the highest severity level. Conclusions The effect of CRS1 on in-hospital mortality is greater than the sum of the effects associated with each of its components, and it increases with the severity of the syndrome. CRS1 accounted for more than half of all mortality, and its positive predictive value approached 30% in-hospital and 50% after discharge. PMID:27907067

    Currently available risk scores (RSs) were derived from populations with very few participants from China. We aimed to develop an RS based on data from patients with acute coronary syndrome in China and to compare its performance with the commonly promoted Global Registry of Acute Coronary Events (GRACE) RS. Clinical Pathways for Acute Coronary Syndromes-Phase 2 was a trial of a quality improvement intervention in China. Patients recruited from 75 hospitals from October 2007 to August 2010 were divided into training and validation sets based on immediate or delayed implementation. A Clinical Pathways for Acute Coronary Syndromes (CPACS) RS for in-hospital mortality was developed separately by gender, using the training set (6,790 patients). Discrimination and calibration of the CPACS RS and GRACE RS were compared on the validation set (3,801 patients). Although discrimination of the GRACE RS was acceptable, this was improved with the CPACS RS (c-statistic 0.82 vs 0.87, p = 0.012 for men; c-statistic 0.78 vs 0.85, p = 0.006 for women). The absolute bias was significantly lower with CPACS RS for both genders (7.6% vs 97.5% in men and 21.5% vs 77.2% in women), compared with the GRACE RS, which systematically overestimated risk. The CPACS RS underestimated risk in women, but only in those already above threshold levels currently used to define a clinical high-risk population. In conclusion, the GRACE RS substantially overestimates the risk of in-hospital death in patients presenting to the hospital with a suspected acute coronary syndrome in China. We have developed and independently validated a new RS utilizing data from Chinese patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    Background: The cardioprotective effect of ischemic preconditioning has been known for many years. Since the temporary ischemia in the heart may cause lethal cardiac effects, the idea of creating ischemia in organs far from the heart such as limbs was raised as remote ischemic preconditioning (RIPC). We hypothesized that the extension of RIPC has more cardioprotective effect in patients undergoing coronary artery bypass graft (CABG) surgeries. Methods: In this triple-blind randomized clinical trial study, 96 patients were randomly divided into 3 groups and two blood pressure cuffs were placed on both upper and lower extremities. In group A, only upper extremity cuff and in group B upper limb and lower limb cuff was inflated intermittently and group C was the control group. RIPC was induced with three 5-min cycles of cuff inflation about 100 mmHg over the initial systolic blood pressure before starting cardiopulmonary bypass. The primary endpoints were troponin I and creatine phosphokinase-myoglobin isoenzyme (CK-MB). Results: Six hours after the termination of CPB, there was a peak release of the troponin I level in all groups (group A=4.90 ng/ml, group B=4.40 ng/ml, and group C=4.50 ng/ml). There was a rise in plasma CK-MB in all groups postoperatively and there were not any significant differences in troponin I and CK-MB release between the three groups. Conclusion: RIPC induced by upper and lower limb ischemia does not reduce postoperative myocardial enzyme elevation in adult patients undergoing CABG.

    Beta-adrenergic blockers exert significant antiarrhythmic activity during ischemia and reperfusion. To further explore the beneficial effects conferred by alpha-1-adrenoceptor blockade on ventricular repolarization dynamicity in the acute phase of myocardial infarction (AMI), we compared carvedilol with metoprolol in the setting of primary percutaneous coronary intervention (PCI). In a prospective study, 100 consecutive patients undergoing primary PCI for AMI were randomized to metoprolol 200 mg/day versus carvedilol 25 mg/day. The first oral dose of study drug was administered and a 24-hour ambulatory electrocardiogram recorded upon hospital admission. Slopes of the linear QT/RR regression were determined before and after reperfusion. A total of 38 recordings of patients treated with metoprolol and 34 recordings of patients with carvedilol were eligible for analysis of QT/RR slopes. The two study groups were similar with respect to age, gender, TIMI perfusion grades, ventricular function, duration of ischemia, and site and size of infarction. Mean RR- and QT-intervals were similar to the metoprolol and carvedilol groups, before and after PCI. Likewise, there was no significant difference in QT/RR slopes between the metoprolol and carvedilol groups before PCI. In contrast, after PCI, there was a trend toward lower QT/RR slopes in the metoprolol group (from 0.18 +/- 0.07 to 0.17 +/- 0.08), and a significant decrease in QT/RR slopes in the carvedilol group (from 0.17 +/- 0.07 to 0.14 +/- 0.09). In patients undergoing successful direct PCI for AMI, treatment with carvedilol, in contrast to metoprolol, was associated with a significant decrease in QT-RR slopes, suggesting greater cardiac electrical stability.

    Full Text Available Background: Several platelet function tests are currently used to measure responsiveness to antiplatelet therapy. This study was to compare two tests, light transmittance aggregometry (LTA and modified thrombelastography (mTEG, for predicting clinical outcomes in Chinese patients after percutaneous coronary intervention (PCI. Methods: Prospective, observational, single-center study of 789 Chinese patients undergoing PCI was enrolled. This study was investigated the correlations between the two tests and performed receiver operating characteristic curve (ROC analysis for major adverse cardiovascular events (MACEs at 1-year follow-up. Results: MACEs occurred in 32 patients (4.1%. Correlations were well between the two tests in the adenosine diphosphate induced platelet reactivity (Spearman r = 0.733, P < 0.001. ROC-curve analysis demonstrated that LTA (area under the curve [AUC]: 0.677; 95% confidence interval [CI]: 0.643-0.710; P = 0.0009, and mTEG (AUC: 0.684; 95% CI: 0.650-0.716; P = 0.0001 had moderate ability to discriminate between patients with and without MACE. MACE occurred more frequently in patients with high on-treatment platelet reactivity (HPR when assessed by LTA (7.4% vs. 2.7%; P < 0.001, and by TEG (6.7% vs. 2.6%; P < 0.001. Kaplan-Meier analysis demonstrated that HPR based on the LTA and mTEG was associated with almost 3-fold increased risk of MACE at 1-year follow-up. Conclusions: The correlation between LTA and mTEG is relatively high in Chinese patients. HPR measured by LTA and mTEG were significantly associated with MACE in Chinese patients undergoing PCI.

    This study evaluated the long-term outcome of patients undergoing emergency coronary artery bypass grafting (eCABG) for cardiogenic shock after acute myocardial infarction. Sixty-seven consecutive patients underwent eCABG for cardiogenic shock at 2 European institutions during an 11-year period. Preoperative, intraoperative, postoperative, and long-term follow-up data of all patients were prospectively collected. Hospital survival was 86% (58 of 67), with all deaths due to cardiac causes. At a mean follow-up of 78 ± 48 months (range, 1 to 153 months), 43 of the 58 patients (74%) discharged from the hospital were alive. Causes of death in 9 of the 15 follow-up deaths (60%) were noncardiac. Overall survival rate at the end of follow-up was 64% (43 of 67). Of the 43 survivors, 41 (95%) were in New York Heart Association Functional Classification I to II, ischemia free, had a Karnofsky performance status exceeding 80, and an excellent quality of life as assessed by the Seattle Angina Questionnaire. The use of cardiopulmonary bypass and the internal thoracic artery were associated with significantly better long-term survival. The long-term survival and quality of life of patients who undergo eCABG for cardiogenic shock after acute myocardial infarction are good, and eCABG should be considered a valuable therapeutic option in this setting. The use of cardiopulmonary bypass and the internal thoracic artery at the time of the operation are strongly advocated. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    The purpose of this study was to examine the relationship between left ventricular (LV) function, cytokine levels and site of myocardial infarction (MI) in patients undergoing coronary artery bypass grafting (CABG). Sixty patients undergoing CABG were divided into three groups (n = 20) according to their history of site of myocardial infarction (MI): no previous MI, anterior MI and posterior/inferior MI. In the pre-operative period, detailed analysis of LV function was done by transthoracic echocardiography. The levels of adrenomedullin, interleukin-1-beta, interleukin-6, tumour necrosis factor-alpha (TNF-α) and angiotensin-II in both peripheral blood samples and pericardial fluid were also measured. Echocardiographic analyses showed that the anterior MI group had significantly worse LV function than both the group with no previous MI and the posterior/inferior MI group (p < 0.05 for LV end-systolic diameter, fractional shortening, LV end-systolic volume, LV end-systolic volume index and ejection fraction). In the anterior MI group, both plasma and pericardial fluid levels of adrenomedullin and and pericardial fluid levels of interleukin-6 and interleukin- 1-beta were significantly higher than those in the group with no previous MI (p < 0.05), and pericardial fluid levels of adrenomedullin, interleukin-6 and interleukin-1-beta were significantly higher than those in the posterior/inferior MI group (p < 0.05). The results of this study indicate that (1) patients with an anterior MI had worse LV function than patients with no previous MI and those with a posterior/inferior MI, and (2) cytokine levels in the plasma and pericardial fluid in patients with anterior MI were increased compared to patients with no previous MI.

    Practice guidelines recommend dual antiplatelet therapy with aspirin and clopidogrel for patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) regardless of in-hospital management strategy. Prasugrel-a thienopyridine adenosine diphosphate receptor antagonist that provides...... higher and less variable levels of platelet inhibition than clopidogrel-has demonstrated benefit when used to treat ACS patients undergoing percutaneous coronary intervention. However, the optimal approach to antiplatelet therapy for high-risk, medically managed NSTE ACS patients remains uncertain...

    We aimed to determine the association between the change in mean platelet volume (MPV) over time and aspirin/ clopidogrel resistance in patients undergoing percutaneous coronary intervention (PCI). The MPV and platelet function were analysed in 302 patients who underwent PCI. MPV changes were associated with increased aspirin reaction units (ARU, r = 0.114; P = 0.047), increased P2Y12 reaction units (PRU, r = 0.193; P = 0.001), and decreased P2Y12% inhibition (PI%, r = - 0.273; P resistant group (≥235 PRU or ≤15% of PI%) showed a significantly higher positive change in MPV (ΔMPV) values than the clopidogrel responder group (0.53 ± 0.78 vs. 0.13 ± 0.69 fL, P resistant and responder groups were 72.6% and 59.3%, respectively. After adjusting for traditional risk factors, the odds ratio in the clopidogrel resistant group with ΔMPV ≥0.2 fL was 4.10 (95% confidence interval; 1.84-9.17). In conclusion, ΔMPV was associated with PRU and PI%; a positive ΔMPV was an independent predictive marker for clopidogrel resistance after PCI.

    The 'smoker's paradox' refers to the observation of favorable prognosis in current smokers following an acute myocardial infarction (AMI). Initial positive findings were in the era of fibrinolysis, with more contemporary studies finding conflicting results. We sought to determine the presence of a 'smoker's paradox' in a cohort of ST Elevation Myocardial Infarction (STEMI) patients identified via field triage, treated with primary percutaneous coronary intervention (pPCI). This was a single center retrospective cohort study identifying consecutive STEMI patients presenting for pPCI via field triage. The primary end points were all cause mortality, major adverse cardiac events (MACE), major bleeding, in-hospital cardiac arrest and length of stay (LOS). A total of 382 patients were included in the study. Current smokers were more likely to be younger (pparadox' does not appear to be relevant among STEMI patients undergoing pPCI, identified via field triage. The previously documented 'smoker's paradox' may have been an indication of patient characteristics and the historical treatment of STEMI with thrombolysis. Further studies with larger numbers may be warranted. © 2013.

    Full Text Available Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET for patients with Cushing’s syndrome (CS undergoing retroperitoneal laparoscopic adrenalectomy (RLA. Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP, levels of serum cortisol, adrenocorticotropin (ACTH, blood glucose, and electrolytes, were acquired and analyzed. Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient’s symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months, except for one patient undergoing bilateral adrenalectomy. Conclusions. This perioperative endocrine therapy for patients with Cushing’s syndrome (mainly for adrenocortical adenoma undergoing retro-laparoscopic adrenalectomy is both effective and safe.

    While multiple growth factor, cytokines, and immune cells are identified in atherosclerotic lesions, as well as an essential nonneuronal function of neurotrophins implicated in cardiovascular tissue development and in lipid and glucose metabolism, the role of the neurotrophins NGF and BDNF and also the adipokine leptin in human coronary atherosclerosis and related disorders, such as metabolic syndrome, remains unclear. Here we report that (i) both the amount and the immunoreactivity of NGF was reduced and the expression of p75NGF receptor and the number of mast cell increased in human atherosclerotic coronary arteries (n = 12) compared with control specimens (n = 9) obtained from autopsy cases, and (ii) NGF and BDNF plasma levels were reduced in patients with metabolic syndrome (n = 23) compared with control subjects (n = 10). Also, in metabolic syndrome patients, a positive correlation between the plasma leptin levels and the number of adipose tissue mast cells was found, suggesting that leptin may be a novel adipoimmune mediator. Altogether, the results provide the first correlative evidence for the potential involvement of NGF, BDNF, leptin, and mast cells in human coronary atherosclerosis and metabolic syndrome, implying neuroimmune and adipoimmune pathways in the pathobiology of these cardiovascular disorders.

    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

    Full Text Available Introduction/Aim. Adiponectin exerts profound protective actions during insulin resistence or prediabetes progression towards more severe clinical entities such as metabolic syndrome and/or cardiovascular disease. Since hypoadiponectinaemia contributes to the pathophysiology of the metabolic syndrome and coronary artery disease the level of circulating adiponectin may be an early marker of cardiovascular events. The aim of this study was to determine the relationships between serum adiponectin levels and parameters of both insulin sensitivity and obesity in patients with the metabolic syndrome and/or coronary artery disease, as well as to assess predictive value of adiponectin serum levels as a biomarker of these entitetis. Methods. The study included 100 patients with metabolic syndrome and/or coronary artery disease with different degree of insulin resistance and healthy, normoglycemic individuals. The control group comprising healthy, normoglycemic individuals was used for comparison. Serum level of adiponectin, fasting glucose, fasting insulinemia Homeostasis Model Assessment of Insulin Resistance (HOMAIR index and anthropometric parameters were determined in all the subjects. Adiponectin was measured by using the ultrasensitive ELISA method. Insulinemia was measured by the radioimmunoassay (RIA method. The presence of glycemic disorders was assessed on the basis of oral glucose tolerance test (OGTT. Results. Adiponectin level was inversely correlated with age (ρ = - 0.015, parameters of both obesity (R = 0.437; p < 0.001 and insulin resistance (R = 0.374; p < 0.01. Decreasing in the level of adiponectin was strongly implicated in the development of insulin resistance. Most importantly, a statistically significant rapid decrease in adiponectin was in the prediabetic stages (p < 0.01. The predictor value of adiponectin was 1,356.32 ± 402.65 рg/mL. Conclusions. The obtained resultats suggest that adiponectin may be a useful marker in

    Full Text Available Turner’s syndrome is a rare congenital disease which affects about 1 in every 2500-3000 live-born females. This happens due to chromosomal abnormalities in a phenotypic female, causing increased gonadotropin concentrations and low concentrations of estrogens from infancy. As a result, hormone replacement therapy is started in most adolescent Turner syndrome patients to initiate and sustain sexual maturation. Accordingly, most Turner’s syndrome patients undergo several decades of estrogen replacement therapy, from puberty to post-menopausal age. The highly publicized findings of the Women’s Health Initiative have called into question the appropriateness of hormone replacement therapy in adolescents with Turner’s syndrome. Those concerns were mostly theoretical extrapolations, as few prospective studies of cancer occurrence in women with Turner syndrome have been reported. Consequently, several recent publications have challenged those extrapolations, based on the assertion that the levels of hormone replacement in Turner syndrome patients are well below the physiologic levels observed in normal menstruating women, as well as the fact that these women are significantly younger than those studied by the Women’s Health Initiative. In discord to those reports, we present a case of ductal carcinoma in-situ in a 40-year-old Turner patient, who had undergone over two decades of combined hormone replacement therapy. The patient underwent an elective excisional biopsy for a palpable mass, with histopathology revealing a complex fibroadenoma with a nidus of ductal carcinoma in-situ. The lesion was noted to be estrogen receptor positive and progesterone receptor negative, with heavy staining for HER-2/Neu receptor. The patient was treated with tamoxifen. While a rare case, it is imperative for the astute clinician to keep in mind the consequences of long-term hormone replacement therapy in Turner’s syndrome patients in order to avoid missed

    Background: Elevated Gamma-glutamyltransferase (GGT) level is independently correlated with conditions associatedwith increased atherosclerosis, such as obesity, elevated serum cholesterol, high blood pressure and myocardial infarction. It is also demonstrated that serum gamma-glutamyltransferase activity is an independent risk factor for myocardial infarction and cardiac death in patients with coronary artery disease. Although the relationship between gamma-glutamyltransferase and coronary artery disease has been reported, not many studies have shown the relationship between changes ofgamma-glutamyltransferase in acute coronary syndromes and a well established coronary risk factor high sensitive C-reactive protein. (hs-CRP). Aims: In this study, how gamma-glutamyltransferase levels changed in acute coronary syndromes and its relationship with high sensitive C-reactive protein if any were studied. Patients & Methods: This trial was carried out at Kosuyolu Cardiovascular Training and Research Hospital and Van Yuksek Ihtisas Hospital, Turkey. 219 patients (177 males and 42 females) presenting with acute coronary syndrome, and 51 control subjects between September 2007 and September 2008 were included in the study. Serum gamma-glutamyltransferase, high sensitive C-reactive protein, serum lipoprotein levels and troponin I were determined. Results: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients compared to control. There was also correlation between gamma-glutamyltransferase and high sensitive C-reactive protein levels. Conclusion: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients. In subgroup analyses, the higher difference with Non-ST elevation myocardial infarction and ST elevation myocardial infarction groups than unstable angina oectoris group proposes a relationship between gamma-glutamyltransferase and severity

    ABSTRACT OBJECTIVE : To analyze if the demographic and socioeconomic variables, as well as percutaneous coronary intervention are associated with the use of medicines for secondary prevention of acute coronary syndrome. METHODS : In this cohort study, we included 138 patients with acute coronary syndrome, aged 30 years or more and of both sexes. The data were collected at the time of hospital discharge, and after six and twelve months. The outcome of the study was the simultaneous use of medicines recommended for secondary prevention of acute coronary syndrome: platelet antiaggregant, beta-blockers, statins and angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker. The independent variables were: sex, age, education in years of attending, monthly income in tertiles and percutaneous coronary intervention. We described the prevalence of use of each group of medicines with their 95% confidence intervals, as well as the simultaneous use of the four medicines, in all analyzed periods. In the crude analysis, we verified the outcome with the independent variables for each period through the Chi-square test. The adjusted analysis was carried out using Poisson Regression. RESULTS : More than a third of patients (36.2%; 95%CI 28.2;44.3) had the four medicines prescribed at the same time, at the moment of discharge. We did not observe any differences in the prevalence of use in comparison with the two follow-up periods. The most prescribed class of medicines during discharge was platelet antiaggregant (91.3%). In the crude analysis, the demographic and socioeconomic variables were not associated to the outcome in any of the three periods. CONCLUSIONS : The prevalence of simultaneous use of medicines at discharge and in the follow-ups pointed to the under-utilization of this therapy in clinical practice. Intervention strategies are needed to improve the quality of care given to patients that extend beyond the hospital discharge, a critical point of transition

    Background Recent studies have shown that thiazolidinediones (TZDs) could reduce in-stent restenosis and improve clinical outcomes in patients with type 2 diabetes after coronary stent implantation. It remains unclear whether nondiabetic patients with metabolic syndrome after stenting could also benefit from the treatment with TZDs.Methods Three hundred and sixty patients with metabolic syndrome who underwent coronary stent implantation were randomly assigned to a rosiglitazone group (n=180) or a control group (n=180). Patients in the rosiglitazone treatment group were treated with rosiglitazone 1 day before coronary stenting (4 mg once daily)and treatment was continued until the 9 months follow-up; while in the control group, patients were treated with placebo 1 day before the procedure and until the 9 months follow-up. Adverse events were death, myocardial infarction and urgent target vessel revascularization within 9 months after coronary stenting.Results One hundred and fifty two patients in the rosiglitazone group and 145 patients in the control group survived during the follow-up. Baseline characteristics among patients in the two groups were well balanced.There was no significant difference in target vessels or the procedure of stent implantation. Compared with the control group, treatment with rosiglitazone was associated with a lower rate of death, myocardial infarction and urgent target vessel revascularization (7.2% vs 14.5%, P=0.044).Conclusion Rosiglitazone could reduce the risk of the adverse cardiovascular event and improve clinical outcomes in nondiabetic patients with metabolic syndrome after coronary stent implantation.

    Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

    Full Text Available We report a case of anomalous left coronary artery from the pulmonary artery (ALCAPA or Bland-White-Garland syndrome, present the challenges of performing a differential diagnosis, and discuss the treatment of the syndrome. Although ALCAPA is a rare congenital heart disease, it is one of the most common causes of myocardial ischemia in childhood and presents a diagnostic challenge. A four-year-old girl was referred to a pediatric cardiologist for evaluation of mitral valve regurgitation murmur and heart failure. The transthoracic echocardiogram demonstrated the left coronary artery (LCA not arising from the aorta, presence of coronary collateral circulation, and moderate mitral valve regurgitation. ALCAPA was confirmed using angiotomography. The LCA was surgically reimplanted into the aorta. After 3 years of postoperative follow-up, the patient developed an LCA aneurysm. Diagnosis of cardiac ischemia in childhood remains a challenge, and careful evaluation of coronary arteries on the echocardiogram is an important tool. In this report, we present a case of ALCAPA with an uncommon postoperative outcome.

    It is well established that clinicians cannot use clinical judgment alone to determine whether an individual patient who presents to the emergency department has an acute coronary syndrome. The history and physical examination do not distinguish sufficiently between the many conditions that can cause acute chest pain syndromes. Cardiac risk factors do not have sufficient discriminatory ability in symptomatic patients presenting to the emergency department. Most patients with non-ST-segment-elevation myocardial infarction do not present with electrocardiographic evidence of active ischemia. The improvement in cardiac troponin assays, especially in conjunction with well-validated clinical decision algorithms, now enables the clinician to rapidly exclude myocardial infarction. In patients in whom unstable angina remains a concern or there is a desire to evaluate for underlying coronary artery disease, coronary computed tomography angiography can be used in the emergency department. Once a process that took ≥24 hours, computed tomography angiography now can rapidly exclude myocardial infarction and coronary artery disease in patients in the emergency department. © 2016 American Heart Association, Inc.

    Abstract There are limited data regarding factors affecting outcomes among acute coronary syndrome (ACS) patients presenting with varying degrees of left ventricle (LV) dysfunction. We aimed to identify factors associated with mortality according to LV ejection fraction (LVEF) at 1st admission in ACS patients. A total of 8983 ACS patients prospectively enrolled in the Acute Coronary Syndrome Israeli Survey (2000–2010) were categorized according to their LVEF at admission: severe LV dysfunction (LVEF ACS, and prognostic factors differ according to LVEF during admission. In patients with severe LV dysfunction signs of clinical instability are related to 1-year mortality; in patients with a more preserved LV function the prognosis is related to the presence of co-morbidities.

    Atherosclerotic cardiovascular disease is an epidemic in today's world. It is one of the most common causes of hospitalization and death. Therefore, remedies to control or heal the disease are continuously sought. In addition to scientifically researched therapies, patients frequently utilize alternative medicine. However, effective and toxic doses, metabolisms, and drug interactions of the herbs and herbal nutrition supplements are largely unknown. Herein, we present two cases with acute coronary syndrome. The first case was admitted with a diagnosis of acute inferior myocardial infaction (MI) and a stent was implanted to the occluded right coronary artery (RCA). There was a 50% stenosis in his left anterior descending artery (LAD). He was admitted with a diagnosis of non-ST elevation MI (NSTEMI) 6 months later. In the coronary angiogram, there was stent restenosis in RCA, the lesion in LAD had become thrombotic and progressed to a stenosis of 90%. He was referred to surgical revascularization. The second case was admitted for acute inferior MI and a stent was implanted to the occluded circumflex artery. Two months later, he was hospitalized for NSTEMI. Progression of coronary plaques to stenosis and stent restenosis was detected and he was referred to surgical revascularization. Both patients used the product sold as Clavis Panax, which contains panax ginseng, tribulus terrestris, and oat, after their first coronary intervention. Intake of a mixture of plant extracts may have serious consequences in humans as drug interactions and side effects are unknown.

    Acute myocardial infarction with spontaneous coronary dissection was fatal in a 33-years-old man. Autopsy and family history revealed type IV Ehlers-Danlos syndrome. In this disease, conjunctive tissue is fragilized due to a deficit in type III collagen which leads to spontaneous ruptures in large and medium sized arteries. The present case is the first with a proven rupture of the coronary arteries. This disease should be entertained in young people with no atherogenous risk factor and an acute coronary disorder since peripheral skin and joint syndromes may be discreet or missing. Treatment is difficult in case of spontaneous coronary dissection. Thrombolysis is not possible and diagnosis may require angiography which is in itself dangerous due to the fragility of the coronary vessels.

    Full Text Available Acute Respiratory Distress Syndrome (ARDS is a potential complication of cardiac surgery, given that patients undergoing CABG frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. Thus, ARDS criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. We aimed to investigate frequency of rapid onset hypoxemia in Pressure of Arterial Oxygen to Fractional Inspired Oxygen Concentration (PaO2/FiO2 less than 200 and diffuse pulmonary infiltrates as two diagnostic criteria forwards and compared these criteria with the clinical picture of the patients after Coronary Artery Bypass Graft (CABG in this study. The study was prospective case series which carried out in about six months. All patients admitted to intensive care unit of Tehran Heart Center, who had undergone CABG on cardiopulmonary pump (CPB recruited in the study. After considering inclusion criteria, age, sex, duration of intubation, arterial blood gas and chest radiography, on 24 hours and 48 hours after admission to the ICU were recorded. Then, patients with rapid onset of hypoxemia (PaO2/FiO2≤200mmHg and diffuse pulmonary infiltrates and without sign or symptoms of obvious heart failure (probable positive ARDS cases criteria were recorded and comparison between these probable positive cases with clinician`s clinical diagnosis (blinded to the study was performed. In this study, a total of 300 patients after on-pump coronary artery bypass surgery were included. Postoperatively, 2 (0.66 % in the 24 hours and 4 (1.33% patients in 48 hours after surgery were positive for the two ARDS criteria according to the checklists, but; nobody had saved persistently ARDS criteria persistently during 48 hours after surgery. At the same time, clinician did not report any case of ARDS among 300 patients. In this study patients with ARDS criteria had no significant differences in age (P.value=0.937 and sex (P

    To date, studies assessing whether the information given to people about screening tests facilitates informed choices have focussed mainly on the UK, US and Australia. The extent to which written information given in other countries facilitates informed choices is not known. The aim of this study is to describe the presentation of choice and information about Down's syndrome in written information about prenatal screening given to pregnant women in five European and two Asian countries. Leaflets were obtained from clinicians in UK, Netherlands, Spain, Italy, Czech Republic, China and India. Two analyses were conducted. First, all relevant text relating to the choice about undergoing screening was extracted and described. Second, each separate piece of information or statement about the condition being screened for was extracted and then coded as either positive, negative or neutral. Only Down's syndrome was included in the analysis since there was relatively little information about other conditions. There was a strong emphasis on choice and the need for discussion about prenatal screening tests in the leaflets from the UK and Netherlands. The leaflet from the UK gave most information about Down's syndrome and the smallest proportion of negative information. By contrast, the Chinese leaflet did not mention choice and gave the most negative information about Down's syndrome. Leaflets from the other countries were more variable. This variation may reflect cultural differences in attitudes to informed choice or a failure to facilitate informed choice in practice. More detailed studies are needed to explore this further.

    Full Text Available Coronary angiography can be a high-risk condition for the incidence of contrast-induced nephropathy (CIN in elderly patients. Reduced glutathione, under a variety of mechanisms, may prevent CIN in this procedure. We prospectively examined whether hydration with reduced glutathione is superior to hydration alone for prevention of CIN in an elderly Han Chinese population. A total of 505 patients (271 males and 234 females aged 75 years or older who underwent non-emergency coronary angiography or an intervention were randomly divided into two groups. The treatment group received hydration with reduced glutathione (n=262 and the control group received hydration alone (n=243. Serum creatinine and blood urea nitrogen levels were measured prior to coronary angiography and 48 h after this procedure. The primary endpoint was occurrence of CIN, which was defined as 25% or 44.2 µmol/L above baseline serum creatinine levels 48 h after the procedure. The overall incidence of CIN was 6.49% in the treatment group and 7.41% in the control group, with no significant difference between the groups (P=0.68. In subgroup analysis by percutaneous coronary intervention, no significant differences were found between the two groups. In summary, reduced glutathione added to optimal hydration does not further decrease the risk of CIN in elderly patients undergoing coronary angiography or an intervention.

    Acute myocardial infarction is the leading cause of non-communicable deaths worldwide. Its diagnosis is a highly complex task for which modeling through automated methods has been attempted. A systematic review of the literature of diagnostic tests that applied intelligent systems tools in the diagnosis of acute coronary syndromes. This manuscript presents a systematic review of the literature from the Medline, Embase, Scopus, IEEE/IET Electronic Library, ISI Web Of Science, Latindex and LILACS databases that includes the diagnostic evaluation of acute coronary syndromes through intelligent systems. The review process was conducted independently by 2 reviewers, and discrepancies were resolved through the participation of a third person. The operational characteristics of the studied tools were extracted. In total, 35 references met the inclusion criteria. In 22 (62.8%) cases, neural networks were used. In five studies, the performances of several intelligent systems tools were compared. Thirteen studies sought to perform diagnoses of all acute coronary syndromes, and in 22, only infarctions were studied. In 21 cases, clinical and electrocardiographic aspects were used as input data; in 10, only electrocardiographic data were used. Most intelligent systems use the clinical context as a reference standard. High rates of diagnostic accuracy were found with better performance using neural networks and support vector machines compared with statistical tools of pattern recognition and decision trees. We found extensive evidence that approaches using intelligent systems tools achieve a greater degree of accuracy than some clinical algorithms or scales and, thus, should be considered appropriate tools for supporting diagnostic decisions of acute coronary syndromes.

    Full Text Available Troponin gives excellent accuracy in the identification of myocardial necrosis, however, it may elevate also in a series of non-atherosclerotic heart diseases. We report the case of a 58-year-old woman with diabetic ketoacidosis (DKA. She had markedly increased levels (90 fold of cardiac biomarkers (troponin I and CK-MB and initial electrocardiography changes compatible with myocardial infarction. She had normal a coronary angiogram. This case shows that nonspecific myocardial injury may occur in DKA with the findings mimicking myocardial infarction including increased level of cardiac biomarkers and electrocardiography changes.

    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 aimed to evaluate the efficacy and safety of bivalirudin use during Percutaneous Coronary Intervention (PCI in the treatment of angina and acute coronary syndrome (ACS. We searched the Cochrane Central Register of Controlled Trials (CENTRAL in the Cochrane Library, PubMed, EMBASE, and Science Direct from January 1980 to January 2016. Randomized controlled trials (RCTs comparing bivalirudin to heparin during the course of PCI in patients with angina or ACS were included. Outcome measures included all-cause mortality, myocardial infarction, revascularisation, stent thrombosis, stroke, and major bleeding. The selection, quality assessment, and data extraction of the included trials were done independently by four authors, and disagreements were resolved by consensus. Pooled relative risk (RR estimates and 95% confidence intervals (CIs were calculated. A total of 12 RCTs involving 44,088 subjects were included. Bivalirudin appeared to be non-superior compared to heparin in reducing all-cause mortality, myocardial infarction, revascularisation, and stroke. Bivalirudin appeared to be related to a higher risk of stent thrombosis when compared to heparin plus provisional use of a glycoprotein IIb/IIIa inhibitor (GPI at day 30 (RR 1.94 [1.16, 3.24] p < 0.01. Overall, bivalirudin-based regimens present a lesser risk of major bleeding (RR 0.56 [0.44–0.71] p < 0.001, and Thrombolysis In Myocardial Infarction (TIMI major bleeding (RR 0.56 [0.43–0.73] compared with heparin-based regimens either with provisional or routine use of a GPI. However, the magnitude of TIMI major bleeding effect varied greatly (p < 0.001, depending on whether a GPI was provisionally used (RR 0.42 [0.34–0.52] p < 0.001 or routinely used (RR 0.60 [0.43 –0.83] p < 0.001, in the heparin arm.

    Full Text Available Introduction & Objective: Ischemic injury of endothelium is associated with prostaglandin synthesis and platelet adhesion and aggregation, which may be associated with the release of aldehydes such as malondialdehyde (MDA. C-reactive protein and cardiac troponin I have been proposed as diagnostic markers of acute coronary syndromes. In this study, we compared the usefulness of plasma MDA as a marker of acute coronary syndromes with that of C-reactive protein and troponin I.Material & Methods: The study population contained 50 patients with unstable angina and 50 patients with acute myocardial infarction admitted to the hearth department of the Ekbatan Hospital of Hamadan. The subjects were matched according to age and sex. Total cholesterol, LDL and HDL cholesterol, triglycerides, plasma MDA, troponin I and C-reactive protein levels were determined in all patients. Results: Results showed that the plasma MDA levels were significantly higher in patients with acute myocardial infarction than in individuals with unstable angina (P<0.001 and were associated with increased levels of troponin I and C-reactive protein (P<0.001.Conclusion: The combination of the plasma MDA levels, which reflect endothelial injury, and troponin I and C-reactive protein levels may allow better discrimination in acute coronary syndromes patients.

    Full Text Available Abstract Background Multiples indices have been described using tissue Doppler imaging (DTI capabilities. The aim of this study was to assess the capability of one or several regional DTI parameters in separating control from ischemic myocardium. Methods Twenty-eight patients with acute myocardial infarction were imaged within 24-hour following an emergent coronary angioplasty. Seventeen controls without any coronary artery or myocardial disease were also explored. Global and regional left ventricular functions were assessed. High frame rate color DTI cineloop recordings were made in apical 4 and 2-chamber for subsequent analysis. Peak velocity during isovolumic contraction time (IVC, ejection time, isovolumic relaxation (IVR and filling time were measured at the mitral annulus and the basal, mid and apical segments of each of the walls studied as well as peak systolic displacement and peak of strain. Results DTI-analysis enabled us to discriminate between the 3 populations (controls, inferior and anterior AMI. Even in non-ischemic segments, velocities and displacements were reduced in the 2 AMI populations. Peak systolic displacement was the best parameter to discriminate controls from AMI groups (wall by wall, p was systematically Conclusion DTI-analysis appears to be valuable in ischemic heart disease assessment. Its clinical impact remains to be established. However this simple index might really help in intensive care unit routine practice.

    Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.

    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.

    We evaluated the effects of myocardial perfusion after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) on gender-based mortality rates. Research has demonstrated a gender-specific response of cardiomyocytes to ischemia and a potential increase in myocardial salvage in women compared with men. Myocardial blush grade (MBG), an angiographic surrogate of myocardial perfusion, is an independent predictor of early and late survival after AMI. Whether the incidence and prognosis of myocardial perfusion differs according to gender among patients with AMI undergoing PCI is unknown. MBG and short- and long-term mortality were evaluated in 1,301 patients (male = 935; female = 366) with AMI randomized to primary angioplasty ± abciximab versus stent ± abciximab. Following PCI, >96% of patients achieved final Thrombolysis In Myocardial Infarction 3 flow, of which MBG 2/3 was present in 58.3% of women versus 51.1% of men (p = 0.02). Worse MBG was an independent predictor of mortality in women at 30 days (7.4% for MBG 0/1 vs 2.4% for MBG 2/3, p = 0.04) and at 1-year (11.0% for MBG 0/1 vs 3.4% for MBG 2/3, p = 0.01); however, MBG was not associated with differences in mortality for men. In conclusion, impaired myocardial perfusion following PCI for AMI, indicated by worse MBG, is an independent predictor of early and late mortality in women but not in men. These findings imply an enhanced survival benefit from restoring myocardial perfusion for women compared with men during primary angioplasty and may have clinical implications for interventional strategies in women.

    BACKGROUND Contrast-induced nephropathy is acute kidney injury caused by contrast medium exposure. Serum creatinine is the clinical diagnostic standard, but it does not yield quick results. The serum level of cystatin C is stable and it can reflect renal function sensitively. The study aimed to assess the usefulness of cystatin C for early diagnosis of contrast-induced nephropathy in patients undergoing coronary angiography. MATERIAL AND METHODS We included 300 patients who underwent CAG. According to the sCr at 48 h, patients were divided into 2 groups: CIN group and non-CIN group. Their demographics and basal renal function were recorded. Changes in sCr, Cys C, and e GFR were compared at the same time. ROC analysis was used to assess the sensitivity and specificity of Cys C in the early diagnosis of CIN. RESULTS Comparison of basal renal function and serum level of Cys C showed no significant differences between the 2 groups. Serum level of Cys C increased significantly at 24 h (p<0.001), and sCr increased significantly at 48 h. ROC analysis showed that the AUC of the change in Cys C between baseline and 24 h was 0.936 (95% CI: 0.879-0.992, p=0.000) and the optimum cut-off level was 0.26 mg/L (sensitivity=89.7% and specificity=95.6%). CONCLUSIONS The concentration change of Cys C is better than sCr as a biomarker in the early detection of CIN.

    Full Text Available Background Depression and anxiety are among the most common mental disorders before and after surgery. Aromatherapy is a treatment that has grown substantially in recent years in comparison with other complementary and alternative medicines (CAM to relieve anxiety. Objectives This study investigated the effect of inhaling lavender essence on the physiological and psychological status of patients who are candidates for coronary artery bypass graft (CABG surgery. Methods This randomized clinical trial was performed on 60 patients who were undergoing CABG surgery at the hospitals of Artesh Jomhory Eslami (AJA University of Medical Sciences in Iran. Patients who met specific inclusion criteria were selected and randomly allocated into two groups: a control group that inhaled room air and an experimental group that inhaled from a piece of cotton impregnated with two drops of lavender essence. This intervention was done on the morning of surgery. To evaluate these measures, a Depression Anxiety Stress Scale (DASS questionnaire was filled out by the patient before and after the intervention. The data collected were analyzed using descriptive and analytic statistics. Results After the intervention, the study results showed statistically significant differences between the two study groups in heart rate (mean = 78.83, P = 0.02 and anxiety level (mean = 6.63, P = 0.02. However, the differences between the two groups were not significant regarding stress level (mean = 8.63, P = 0.55 and other physiological variables. Conclusions Inhalation aromatherapy is an effective method for reducing the heart rate and the level of anxiety in patients before CABG surgery. Given that the physiological and psychological health of patients are important responsibilities for nurses, aromatherapy can be considered a safe and effective relaxation method before invasive interventions. Learning this method is recommended for students and nurses.

    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

    This study aimed to (a) investigate whether atorvastatin reload protects against acute heart failure (AHF) in patients with stable coronary artery disease (CAD) undergoing noncardiac emergency surgery and decreases the incidence of major adverse cardiac events (MACE) during hospitalization and (b) elucidate its possible mechanism of action. In total, 500 patients with stable CAD before noncardiac emergency surgery were randomized either to the atorvastatin reload or to the placebo group. All patients received atorvastatin treatment postoperatively. The primary end point was the incidence of AHF during hospitalization, and the secondary end point was the incidence of MACE during hospitalization. Preoperative and 72 h postoperative changes in high-sensitivity C-reactive protein and interleukin-6 levels were compared between the two groups. AHF during hospitalization occurred in 5.2% of patients in the atorvastatin reload group and 11.2% in the placebo group (P=0.0225). MACE during hospitalization occurred in 2.4% of patients in the atorvastatin reload group and 8.0% in the placebo group (P=0.0088). According to multivariable analysis, atorvastatin reload conferred a 50% reduction in the risk of AHF during hospitalization (odds ratio, 0.50; 95% confidence interval, 0.2-0.8; P=0.005). The median decrease in the high-sensitivity C-reactive protein and interleukin-6 levels was significantly greater in the atorvastatin reload group (Pemergency surgery by decreasing the incidence of AHF and MACE during hospitalization. The mechanism of this protective effect may involve inhibition of inflammation.

    Background Despite outstanding antiplatelet properties of aspirin and clopidogrel,some patients taking these drugs continue to suffer complications.Antiplatelet resistance appears to be a new prognostic factor in acute coronary syndrome patients for clinical events associated with stent thrombosis (ST).However,there is no optimal method to identify it and assess its correlation to clinical outcomes.This study sought to evaluate the predictive value of antiplatelet resistance assessed by whole blood impedance aggregometry for the risk of early ST in patients with acute coronary syndrome who underwent coronary stenting.Methods Platelet responses to aspirin and clopidogrel in 86 patients with acute coronary syndrome were measured by whole blood impedance aggregometry.Spontaneous platelet aggregation was defined as antiplatelet resistance identified by the increased electrical impedance.The clinical endpoint was early stent thrombosis during 30-day follow-up after coronary stenting.Results The prevalence of aspirin resistance,clopidogrel resistance and dual resistance of combined clopidogrel and aspirin resistance were 19.8%,12.8% and 5.8% respectively.Diabetes,female and higher platelet counts were more frequently detected in clopidogrel-resistant and dual-resistant patients.During 30-day follow-up,the patients with clopidogrel resistance and dual resistance had higher incidence of early stent thrombosis (18.2% vs.1.3%,40.0% vs.1.2%,P <0.05).Binary Logistic Regression analysis indicated that dual resistance remained an independent predicator for early stent thrombosis (odds ratio 34.064,95% CI 1.919-604.656,P=-0.016).Conclusions Antiplatelet resistance assessed by whole blood impedance aggregometry is paralleled to clinical events,and dual antiplatelet resistance is an independent predicator for early stent thrombosis in patients with acute coronary syndrome.As a physiological assessment of platelet reactivity,whole blood impedance aggregometry is a

    Full Text Available Aim To evaluate the effect of perioperative statin treatment on postoperative atrial fibrillation and cardiac mortality in patients undergoing coronary artery bypass grafting. Methods A total of 1890 patients who underwent isolated coronary artery bypass were analyzed retrospectively, of which 425 patients (22.4% older than 70 were included in the study. The demographic properties, preoperative, operative and postoperative data and other medications of these patients were recorded. Continuous preoperative and postoperative atorvastatin therapy were received by 124 (29.17% patients; 301 (70.82% patients were matched to a control group (no-statin group. The two groups were matched by propensity score analysis in terms of atrial fibrillation development and cardiac mortality. Results Medical history, medical treatment, cardiovascular history, and operative characteristics demonstrated significant heterogeneity in both groups. Postoperative atrial fibrillation was similar in both groups. Before propensity score matching, the percentages of patients in postoperative atrial fibrillation with respect to Atorvastain-group and No-statin-group were 13.71 and 10.3 respectively; however, those were 13.71 and 14.51 after matching. In a multivariate regression analysis, five-vessel bypass (odds ratio OR, 2.354; 95% confidence interval CI, 0.99 to 5.57 was an independent predictor of postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting. In-hospital mortality was higher in the Atorvastatin-group compared with the No-statingroup: 124 (8.9% versus 301 (3.7%, respectively; p=0.027. Conclusion Perioperative atorvastatin treatment is not found to be associated with reduced postoperative atrial fibrillation and cardiac mortality in patients undergoing isolated coronary artery bypass grafting above the age of seventy years.

    Background Adenosine phosphate-mediated platelet aggregation is a prognostic factor for major adverse cardiac events in patients who have undergone selective percutaneous coronary interventions. This study aimed to assess whether an adjusted loading dose of clopidogrel could more effectively inhibit platelet aggregation in patients undergoing selected percutaneous coronary intervention.Methods A total of 205 patients undergoing selected percutaneous coronary intervention were enrolled in this multicenter, prospective, randomized study. Patients receiving domestic clopidogrel (n=104) served as the Talcom (Taijia)group; others (n=101) received Plavix, the Plavix group, Patients received up to 3 additional 300-mg loading doses of clopidogrel to decrease the adenosine phosphate-mediated platelet aggregation index by more than 50% (the primary endpoint) compared with the baseline. The secondary endpoint was major adverse cardiovascular events at 12 months.Results Compared with the rational loading dosage, the tailored loading dosage better inhibited platelet aggregation based on a >50% decrease in adenosine phosphate-mediated platelet aggregation (rational loading dosage vs. tailored loading dosage, 48% vs. 73%, P=0.028). There was no significant difference in the eligible index between the Talcom and Plavix groups (47% vs. 49% at 300 mg; 62% vs. 59% at 600 mg; 74% vs. 72% at 900 mg; P >0.05) based on a standard adenosine diphosphate-mediated platelet aggregation decrease of >50%. After 12 months of follow-up, there were no significant differences in major adverse cardiac events (2.5% vs. 2.9%, P=5.43). No acute or subacute stent thrombosis events occurred.Conclusion An adjusted loading dose of clopidogrel could have significant effects on antiplatelet aggregation compared with a rational dose, decreasing 1-year major adverse cardiac events in patients undergoing percutaneous coronary interventions based on adenosine phosphate-mediated platelet aggregation with no

    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.

    Pheochromocytomas are neuroendocrine tumors, and its cardiac involvement may include transient myocardial dysfunction, acute coronary syndrome (ACS), and even ventricular arrhythmias.A patient was referred for evaluation of stuttering chest pain, and his electrocardiogram showed T-wave inversion over leads V1 to V4. Coronary angiography showed 90% stenosis in the mid-left anterior descending coronary artery (LAD), which was stented. Five days later, the patient had ventricular tachycardia, and severe hypertension, remarkable blood pressure fluctuation between 224/76 and 70/50 mm Hg. The patient felt abdominal pain and his abdominal ultrasound showed suspicious right adrenal gland tumor. Enhanced computed tomography of adrenal gland conformed that there was a tumor in right adrenal gland accompanied by an upset level of aldosterone.The tumor was removed by laparoscope, and the pathological examination showed pheochromocytoma. After the surgery, the blood pressure turned normal gradually. There was no T-wave inversion in lead V1-V4. Our case illustrates a rare pheochromocytoma presentation with a VT and resembling ACS. In our case, the serious stenosis in the mid of LAD could be explained by worsen the clinical course of myocardial ischemia or severe coronary vasospasm by the excessive amounts of catecholamines released from the tumor. Coronary vasospasm was possible because he had no classic coronary risk factors (e.g. family history and smoking habit, essential hypertension, hyperglycemia and abnormal serum lipoprotein, high body mass index). Thus, pheochromocytoma was missed until he reveal
