We determined in-hospital and 1-year prognoses after acute myocardial infarction (MI) in 5,839 consecutive patients derived from 14 of 21 coronary care units in Israel during 1981-1983. Age-adjusted in-hospital mortality was 23.1% in 1,524 women and 15.7% in 4,315 men (p less than 0.0005). One-year age-adjusted mortality rates in patients surviving hospitalization were 11.8% in women and 9.3% in men (p = 0.03). Cumulative age-adjusted 1-year mortality rates were 31.8% in women and 23.1% in men (p less than 0.0005). Relative odds of mortality, covariate-adjusted for major prognostic factors that included age, prior MI, congestive heart failure, and infarct location by electrocardiogram, indicated that female gender was independently and significantly associated with increased mortality both during hospitalization (relative odds, 1.72; 95% confidence interval, 1.45-2.04) and at 1 year after discharge (relative odds, 1.32; 95% confidence interval, 1.05-1.66). In separate multivariate analyses for each gender, a major factor that emerged as a predictor of outcome in women, but not in men, was a reported history of diabetes mellitus, both for in-hospital mortality and for 1-year mortality. However, even in the nondiabetics in this population, female gender was a significant, independent predictor of in-hospital mortality. The findings of the present study substantiate that women fare worse than men after suffering an acute MI, that increased age does not fully account for the increased mortality in women, and that diabetic women are at particularly high risk once MI has occurred.

The aim of the study was to assess the relationship between paroxysmal atrial fibrillation during acute myocardial infarction and the long-term prognosis of patients after acute myocardial infarction. The incidence of paroxysmal atrial fibrillation among 5803 consecutive hospitalized patients was 9.9% (557/5803). Incidence rose with increasing age (less than or equal to 59 years, 4.2%), (60-69 years, 10.5%), (greater than or equal to 70 years, 16.0%) and was slightly (but not significantly) higher in women (11.0%) than in men (9.6%). The presence of congestive heart failure and mean age represented two major discriminants between patients with paroxysmal atrial fibrillation (70% and 68.6 years) in comparison with their counterparts (35% and 62.3% years). Hospital mortality was significantly higher (25.5%) in patients with paroxysmal atrial fibrillation than in those without (16.2%). However, the effect of paroxysmal atrial fibrillation disappeared when other factors influencing the short term prognosis (i.e. heart failure) were taken into account by a multivariate logistic regression analysis. The covariate adjusted relative odds of in-hospital mortality then fell to 0.82. The 1- and 5-year mortality rates were 18.6% and 43.3% in patients with paroxysmal atrial fibrillation as compared to 8.2% and 25.4% (P less than 0.001), respectively, in patients free of paroxysmal atrial fibrillation. Using a proportional hazards analysis of mortality through the first quarter of 1988 (average follow-up time, 5.5 years) the net risk of dying among patients with paroxysmal atrial fibrillation complicating the acute myocardial infarction is estimated at 1.28 (90% confidence interval, 1.12-1.46) relative to counterparts free of the complication.(ABSTRACT TRUNCATED AT 250 WORDS)

Current cigarette smoking is a powerful independent predictor of SCD risk in patients with CAD. Patients who quit smoking experienced a significant reduction in SCD risk. Thus, efforts to reduce mortality from SCD in patients with CAD should include vigorous smoking cessation strategies.

for the BIP Study GroupBackground-The association between elevated blood triglyceride levels and subsequent mortality risk in patients with established coronary heart disease (CHD) has been investigated rarely. The aim of the present study was to investigate this association. Methods and Results-We evaluated mortality over a mean follow-up time of 5.1 years among 9033 male and 2499 female CHD patients who were screened for participation in the Bezafibrate Infarction Prevention (BIP) Study. A stepwise increase in mortality with increasing serum triglyceride levels was observed in patients with desirable or elevated serum total cholesterol levels and in patients with either desirable or abnormally low HDL cholesterol levels. Multivariate adjustment for factors other than HDL cholesterol yielded a slightly increased adjusted mortality risk with a 1-natural-log-unit elevation of triglyceride levels in men (hazard ratio [HR] 1.14, 95% CI 1.00 to 1.30) and women (HR 1.37, 95% CI 1.04 to 1.88). Excess covariate-adjusted risk was noted among patients with elevated total and LDL cholesterol and in women with HDL cholesterol levels Ͼ45 mg/dL. After additional adjustment for HDL cholesterol, the risk of mortality with a 1-natural-log-unit elevation of triglycerides declined in men (HR 1.09, 95% CI 0.94 to 1.26) and in women (HR 1.10, 95% CI 0.80 to 1.50). A trend for increased mortality risk remained in patients with elevated total and LDL cholesterol and in women with HDL cholesterol Ͼ45 mg/dL. Conclusions-Elevated triglyceride levels were associated with a small, independent increased mortality risk in CHD patients. This risk may be increased among subgroups of patients with elevated total cholesterol and LDL cholesterol levels. (Circulation. 1999;100:475-482.)
