Moderate alcohol consumption is associated with reduced long-term cardiovascular risk in patients following a complicated acute myocardial infarction.
BACKGROUND
The impact on prognosis of alcohol use in patients with coronary artery disease remains uncertain. We related alcohol use to all-cause mortality, cardiovascular (CV)-mortality and hospitalization in patients following a complicated myocardial infarction (MI).


METHODS
In the OPTIMAAL trial, 5477 patients from 7 Western European countries with heart failure and/or evidence of left ventricular dysfunction following MI were recruited. Following randomization median 3 days, patients were asked to assess their average alcohol consumption prior to the index infarction. Patients were stratified by the frequency of the use of alcohol into either non-users (n = 2160), moderate users (1-7 drinks/week, n = 2753) and heavy users (> 7 drinks/week, n = 545) and related to prespecified clinical outcomes in the groups.


RESULTS
A total of 5477 patients were included in the trial. During the follow-up period of 2.7 years 946 deaths were reported. Adjusted for age and smoking status, patients with moderate use of alcohol had 24% lower risk of all-cause death (p < 0.001), 26% lower risk of CV-death (p < 0.000) and 8% lower risk for hospitalization (p = 0.030) than abstainers. There was no significant difference between non-drinkers and heavy drinkers with regard to survival following adjustment for age and smoking status.


CONCLUSIONS
Our results demonstrate a strong positive association between moderate alcohol use and survival in a cohort of patients following complicated MI. Both heavy drinkers and abstainers had poorer prognosis, with no significance difference between those 2 groups.
