Alcohol consumption and severity of angiographically determined coronary artery disease in Japanese men and women

The relation of alcohol consumption to the severity of coronary atherosclerosis was examined among 323 men and 220 women who underwent coronary arteriography. Severity of coronary atherosclerosis was assessed by the number of vessels obstructed greater than or equal to 75% in diameter and Gensini's severity score. Alcohol consumption was divided into 5 categories in men (never, past. 1-24, 25-49, and greater than or equal to 50 mi per day) and 3 categories in women (never, past, and current). Among men, odds ratios of severe stenosis (multiple-vessel disease or Gensini's score > 15) decreased substantially and significantly in all current drinking categories but without dose-response effect. There was a weak, inverse association of current alcohol consumption with one-vessel disease. bur not with moderate stenosis in terms of Gensini's score (less than or equal to 15). Past drinkers showed a fairly large, but statistically nonsignificant, decrease in the odds ratios of not only severe stenosis but also of moderate stenosis. Among women, current drinkers showed a small. statistically nonsignificant decrease in the risk of severe stenosis in terms of Gensini's score. These associations with alcohol use did not change after adjustment for known coronary risk factors. The present findings add to evidence that alcohol drinking confers protection against coronary atherosclerosis. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
