Association of the 894G>T polymorphism in the endothelial nitric oxide synthase gene with risk of acute myocardial infarction
Background: This study was designed to investigate the association of the 894G>T polymorphism in the eNOS gene with risk of acute myocardial infarction (AMI), extent of coronary artery disease (CAD) on coronary angiography, and in-hospital mortality after AMI.
Methods: We studied 1602 consecutive patients who were enrolled in the GEMIG study. The control group was comprised by 727 individuals, who were randomly selected from the general adult population.
Results: The prevalence of the Asp298 variant of eNOS was not found to be significantly and independently associated with risk of AMI (RR = 1.08, 95%CI = 0.77–1.51, P = 0.663), extent of CAD on angiography (OR = 1.18, 95%CI = 0.63–2.23, P = 0.605) and in-hospital mortality (RR = 1.08, 95%CI = 0.29–4.04, P = 0.908).
Conclusion: In contrast to previous reports, homozygosity for the Asp298 variant of the 894G>T polymorphism in the eNOS gene was not found to be associated with risk of AMI, extent of CAD and in-hospital mortality after AM
The additional value of patient-reported health status in predicting 1-year mortality after invasive coronary procedures: A report from the Euro Heart Survey on Coronary Revascularisation
Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p<0.10 in the unadjusted analyses. In the adjusted analyses, problems with self-care (OR 3.45; 95% CI 2.14 to 5.59) and a low rating (≤ 60) on health status (OR 2.41; 95% CI 1.47 to 3.94) were the most powerful independent predictors of mortality, among the 22 clinical variables included in the analysis. Furthermore, patients who reported no problems on all five dimensions had significantly lower 1-year mortality rates (OR 0.47; 95% CI 0.28 to 0.81). Conclusions: This analysis shows that impaired health status is associated with a 2-3-fold increased risk of all-cause mortality in patients with CAD, independent of other conventional risk factors. These results highlight the importance of including patients' subjective experience of their own health status in the evaluation strategy to optimise risk stratification and management in clinical practice

Arterial stiffness predicts risk for long-term recurrence in patients with type 2 diabetes admitted for acute coronary event
Objectives: to investigate the predictive value of arterial stiffness (AS) estimation for long-term recurrences in patients with type 2 diabetes (DM2) following acute coronary event. Patients and methods: prospective observational study involving 119 DM2 patients without history of coronary heart disease admitted with ST-segment elevation myocardial infarction (STEMI). Medical history, anthropometrics, smoking, HbA1c, lipid profile, troponine-I levels, and left ventricular ejection fraction (LVEF) were recorded. Carotid-femoral pulse wave velocity (cf-PWV) was measured 1 month after discharge. Patients were followed up for 36 months or to reach an end-point: cardiovascular death, acute coronary event, angioplasty or hospitalization for acute heart failure. To facilitate analysis, patients were divided into two groups according to cf-PWV, using the accepted cut-off value of 12 m/s. Results: overall, 34 patients had a recurrence. In Kaplan-Meier analysis patients with cf-PWV > 12 m/s had mean time-to-event 353 +/- 43 days compared to 505 +/- 115 days for patients with cf-PWV <= 12 m/s, log rank = 0.0252. In multivariate analysis factors independently associated with recurrence were age (66.53 +/- 6.87 vs. 61.54 +/- 10.77 years, p = 0.015), LVEF (41.66 +/- 8.21 vs. 47.58 +/- 8.11%, p = 0.001) and cf-PWV (13.94 +/- 2.91 vs. 12.35 +/- 2.77 m/s, p = 0.008). Conclusions: AS estimation in patients with DM2 after STEMI discriminate patients at higher risk for 3-year recurrence, and maybe valuable for distinguishing patients likely to require a more rigorous therapeutic intervention.
