Objective - Moderate alcohol consumption is associated with reduced cardiovascular disease (CVD) risk. Whether this protection is based on a lesser degree of coronary atherosclerosis has not been established. Methods and Results - We studied 1676 men and 465 women consecutively undergoing coronary angiography. A score (ATS) was calculated by summing the percent lumen narrowing of all main vessels; alcohol consumption was quantitated by questionnaire. In univariate analysis, ATS was significantly (P <= 0.001) associated with male sex, age, familial CVD, smoking, diabetes, hypertension, and serum cholesterol levels; alcohol consumption was associated with less frequent diabetes (P < 0.001) and lower ATS (P=0.02). By multivariate analysis, alcohol intake was associated with lower ATS (P < 0.01) independently of the other risk factors; the estimated effect size was comparable to that associated with a 1-mmol decrement in serum cholesterol. Over a median follow-up of 93 months, 37 women and 194 men died from a cardiac cause. By Cox analysis, positive predictors for cardiac mortality were male sex (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.1 to 2.6]), age (HR, 2.1; 95% CI, 1.8 to 2.5 per decade) and diabetes (HR, 1.7; 95% CI, 1.2 to 2.4), whereas alcohol consumption was the only negative predictor (HR, 0.84; 95% CI, 0.71 to 1.00). Conclusions - In a selected high-risk population, moderate alcohol consumption was independently associated with less coronary atherosclerosis and lower risk for cardiac mortality.
