More than 100 prospective studies show an inverse association between moderate drinking and risk of heart attack, ischemic (clot-caused) stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes. (1) The effect is fairly consistent, corresponding to a 25 percent to 40 percent reduction in risk. Here are the results of some large prospective studies of alcohol consumption and cardiovascular disease.
|| Association with Moderate Alcohol Consumption*
|Japan Collaborative Cohort Study for Evaluation of Cancer Risk cohort: 97,432 men and women aged 40–79||10 years||12%–20% decreased risk of all-cause mortality in men and women who consumed less than 23 grams per day of alcohol; heavy drinking increased the risk of all-cause mortality (2)|
|Health Professionals Follow-up Study: 38,077 male health professionals aged 40–75||12 years||35% reduced risk of myocardial infarction (3)|
|Eastern France cohort: 34,014 men and women||
|25–30% reduced risk of cardiovascular death (4)|
|Cancer Prevention Study II: 489,626 men and women aged 30–104||9 years||30–40% reduced risk of cardiovascular death; mortality from all causes increased with heavier drinking, particularly among adults under age 60 (5, 6)|
|Physicians’ Health Study: 22,071 male physicians aged 40–84||11 years||30–35% reduced risk of angina and myocardial infarction, 20–30% reduced risk of cardiovascular death (7)|
|Kaiser Permanente cohort: 123,840 men and women aged 30+||10 years||40% reduction in fatal myocardial infarction, 20% reduction in cardiovascular mortality; 80% increase in fatal hemorrhagic stroke (8)|
|Nurses’ Health Study: 85,709 female nurses aged 34–59||12 years||17% lower risk of all-cause mortality; an earlier report showed a 40% reduction in risk of CHD and 70% reduction in risk of ischemic stroke (9)|
