Light Alcohol Consumption Prior to and Following Myocardial Infarction Is Associated with Lower Risk of Mortality
This study examined the association between long-term alcohol consumption, consumption before and after myocardial infarction (MI), and all-cause and cardiovascular mortality among participants in the Health Professionals Follow-up Study (HPFS). Of the >51,000 men in the study, 1818 experienced incident nonfatal MI during ≥20 years of follow-up. Among MI survivors, 468 died during follow-up. Reports of alcohol consumption were obtained throughout the course of the study and were used to calculate average consumption prior to and following MI.
- Overall, compared with no alcohol consumption, pre-MI and post-MI intake of very light* to light** amounts of alcohol was associated with lower risk of all-cause mortality and cardiovascular morality.
- The reductions in all-cause mortality risk (22% lower among those consuming very light amounts and 34% lower among those consuming light amounts, compared with nondrinkers) were no longer present in men who consumed ≥30 g per day. For this highest consumption group, the adjusted hazard ratio was 0.87 (95% CI, 0.61–1.25).
