Abstract

BACKGROUND & AIMS:

Controversy exists on the association between alcohol consumption and risk of heart failure (HF). We carried out a meta-analysis to summarize available prospective data on alcohol consumption and HF.

METHODS:

We searched PubMed for relevant studies published until January 1, 2017. Relative risk (RR) estimates from individual studies were pooled in a random-effects meta-analysis.

RESULTS:

A total of 13 prospective studies, with 13,738 HF cases and 355,804 participants, were included in the meta-analysis. Light alcohol drinking (0.1-7 drinks/week) was inversely associated with risk of HF (RR, 0.86; 95% confidence interval, 0.81-0.90). There was no statistically significant association between moderate (7.1-14 drinks/week), high (14.1-28 drinks/week), or heavy (>28 drinks/week) alcohol consumption and HF risk. Former drinking was associated with an increased risk of HF compared with never or occasional drinking (RR, 1.22; 95% confidence interval, 1.11-1.33).

CONCLUSIONS:

This meta-analysis found that light alcohol drinking was associated with a lower risk of HF. Former drinking was associated with a higher risk of HF.
