Introduction. The prognosis of acute coronary syndrome (ACS) patients has been improved with several treatments such as antithrombotics, beta-blockers, and angiotensin-converting enzyme inhibitors (ACEI) as well as coronary revascularization. Influenza vaccination has been shown to reduce adverse outcomes in ACS, but no information exists regarding the interaction of other treatments.Methods. This study included 439 ACS patients from Phrommintikul et al. A single dose of inactivated influenza vaccine was given by intramuscular injection in the vaccination group. The cardiovascular outcomes were described as major cardiovascular events (MACEs) which included mortality, hospitalization due to ACS, and hospitalization due to heart failure (HF). The stratified and multivariable Cox’s regression analysis was performed.Results. The stratified Cox’s analysis by influenza vaccination for each cardiovascular outcome and discrimination of hazard ratios showed that beta-blockers had an interaction with influenza vaccination. Moreover, the multivariable hazard ratios disclosed that influenza vaccine is associated with a significant reduction of hospitalization due to HF in patients who received beta-blockers (HR = 0.05, 95% CI = 0.004–0.71,P=0.027), after being adjusted for prognostic indicators (sex, dyslipidemia, serum creatinine, and left ventricular ejection fraction).Conclusions. The influenza vaccine was shown to significantly modify the effect of beta-blockers in ACS patients and to reduce the hospitalization due to HF. However, further study of a larger population and benefits to HF patients should be investigated.

Purpose: to elucidate independent clinical and laboratory predictors of adverse cardiovascular events (ACVE) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI) with stenting in early inhospital period.Materials and methods. We included in this prospective single center study 130 patients with ACS who underwent PCI with stenting. All patients prior to and after PCI received dual antiplatelet therapy with acetylsalicylic acid and clopidogrel. In 12–48 hours after PCI we measured residual platelet reactivity (RPR) using light aggregometry. In 57 patients simultaneously we performed genotyping of CYP2C19*2 polymorphisms. The following ACVE were used as end­points and were registered during inhospital observation (mean duration 9.7±3.2 days): sudden death, stent thrombosis, arterial thrombosis of other localization, recurrent angina, cardiac rhythm disturbances requiring special therapy.Results. Repetitive ACVE were observed in 32 patients. According to unifactorial regression analysis risk factors of their development were, ADP F­induced RPR (р<0.001), levels of creatinine (р<0.001), hemoglobin (р<0.001), and glucose (р=0.026), age (р=0.01), iron­deficiency anemia (р=0.01), left ventricular ejection fraction (р=0.004), number of stents (р=0.015). According to results of multifactorial regression analysis independent predictors of ACVE were: ADP­induced RPR >76 % (р=0.003), levels of creatinine >189 µmol / L (р=0.003), and hemoglobin <114 g / L (р=0.004). Significant effect of homozygous carriage of CYP2C19*2 (G681A) (А / А) on development of stent thrombosis was also detected (р=0.028).Conclusion. ADP­induced RPR, levels of creatinine and hemoglobin were found to be independent predictors of inhospital ACVE after myocardial revascularization with stenting in patients with ACS.

Objective. This double-blind and randomized placebo-controlled trial evaluated the safety and efficacy of Danhong injection combined with Naoxintong capsule in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods. ACS patients scheduled to undergo PCI (n=130) were equally and randomly apportioned to either a treatment or control group. After PCI, the treatment group received Danhong injection combined with Naoxintong capsule for 12 weeks, while the control group was given placebo. Both groups were otherwise treated with conventional secondary prevention of coronary artery disease. The groups were primarily evaluated for clinical efficacy and cardiovascular events. Evaluative indicators of safety included adverse events, platelet count, and liver, renal, and blood coagulation functions. Result. No cardiovascular events or adverse reactions were observed in either group. The treatment group demonstrated better signs of clinical efficacy, including left ventricular ejection fraction, higher nitric oxide levels, and lower levels of endothelin-1 (ET-1) and von Willebrand factor (VWF). Conclusion. ACS patients treated with Danhong injection combined with Naoxintong capsule after PCI demonstrated better improvement with regard to markers associated with atherosclerosis and adverse cardiovascular events, without apparent adverse effects. Thus, Danhong injection combined with Naoxintong capsule was safe and effective for treating ACS patients after PCI.

Abstract Background Coronary artery ectasia (CAE) is a rare anomaly that can present at any age. Predisposing risk factors include Kawasaki disease in a younger population and atherosclerosis in the older generation. We present a unique case of the management of a young woman diagnosed with multivessel CAE with aneurysmal changes in the setting of acute coronary syndrome and subsequently during pregnancy. Case summary A 23-year-old woman presented with acute onset chest pain. Electrocardiogram revealed no ischaemic changes; however, troponin I peaked at 16 ng/mL (reference range 0–0.04 ng/mL). Echocardiogram showed apical dyskinesis with preserved left ventricular ejection fraction. Coronary angiography showed multivessel CAE along with significant thrombus burden in an ectatic lesion of the left anterior descending artery. Since the patient was haemodynamically stable, conservative management with dual antiplatelet therapy and anticoagulation was started. On follow-up, coronary computed tomographic angiogram illustrated resolution of the coronary thrombi and echocardiogram showed improvement to the apical dyskinesis. It was presumed that Kawasaki disease was the most likely aetiology of her disease. Subsequently the patient reported that, contrary to medical advice, she was pregnant, adding another layer of complexity to her case. Discussion Coronary artery ectasia can be discovered as an incidental finding or can present with an acute coronary syndrome. Management is challenging in the absence of randomized trials and large-scale data. Treatment options include medications, percutaneous intervention, and surgical revascularization. Close surveillance is required in these patients to assess progression of disease. Here we discuss treatment options during acute coronary syndrome and pregnancy.

Abstract Background The aim of this study was to determine the difference in effects of beta-blockers on long-term clinical outcomes between ischemic heart disease (IHD) patients with mid-range ejection fraction (mrEF) and those with reduced ejection fraction (rEF). Methods Data were assessed of 3508 consecutive IHD patients who underwent percutaneous coronary intervention (PCI) between 1997 and 2011. Among them, 316 patients with mrEF (EF = 40–49%) and 201 patients with rEF (EF < 40%) were identified. They were assigned to groups according to users and non-users of beta-blockers and effects of beta-blockers were assessed between mrEF and rEF patients, separately. The primary outcome was a composite of all-cause death and non-fatal acute coronary syndrome. Results The median follow-up period was 5.5 years in mrEF patients and 4.3 years in rEF patients. Cumulative event-free survival was significantly lower in the group with beta-blockers than in the group without beta-blockers in rEF (p = 0.003), whereas no difference was observed in mrEF (p = 0.137) between those with and without beta-blockers. In the multivariate analysis, use of beta-blockers was associated with reduction in clinical outcomes in patients with rEF (hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.36–0.97; p = 0.036), whereas no association was observed among those with mrEF (HR 0.74; 95% CI 0.49–1.10; p = 0.137). Conclusions Our observational study showed that use of beta-blockers was not associated with long-term clinical outcomes in IHD patients with mrEF, whereas a significant association was observed in those with rEF.

Background: In the diagnosis of acute coronary syndrome, cardiac troponin I is highly reliable and widely available biomarker. Serum level of cardiac troponin I is related to amount of myocardial damage and also closely relates to infarct size. Our aim of the study is to find out the relationship between cardiac troponin I and left ventricular systolic function after acute coronary syndrome. Methods: Total of 132 acute coronary syndrome patients were included in this study after admission in coronary care unit of Sir Salimullah Medical College, Mitford Hospital. Troponin I level was measured at admission and left ventricular ejection fraction (LVEF) was measured by echocardiography between 12-48 hours of onset of chest pain. Results: There was negative correlation between Troponin I at 12 to 48 hours of chest pain with LVEF in these study patients. With a cutoff value of troponin I e”6.8 ng/ml in STEMI patients there is a significant negative relation between 12 to 48 hrs troponin I and LVEF (p<0.001). Sensitivity of troponin I e” 6.8 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% in STEMI was 93.75% and specificity was 77.78%. In NSTEMI sensitivity of troponin I e” 4.5 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% was 65% and specificity was 54.05%. Conclusion: Serum troponin I level had a strong negative correlation with left ventricular ejection fraction after acute coronary syndrome and hence can be used to predict the LVEF in this setting.
