Introduction and methods

In contrast to conflicting data on the relationship between previous alcohol use and the development of heart failure (HF), there is a lack of data regarding the safety of alcohol consumption in patients after a new diagnosis of HF. Previous studies focusing on alcohol consumption in adults with HF were limited to subjects with prevalent disease [1-4], possibly leading to a survivor bias influencing the outcomes.

This subanalysis of the Cardiovascular Health Study (n=5888) therefore examined the association between alcohol consumption and survival following the diagnosis of HF in older adults. This prospective cohort study (January to September 2016) included 393 community-dwelling adults aged ≥65 years with incident HF, which had been diagnosed during the first 10 years of the Cardiovascular Health Study. After a baseline clinical examination, participants attended nine yearly clinic visits. An alcoholic beverage was defined as a: 12-oz beer, 6-oz glass of wine, or a shot (1.5 ounces) of liquor. Weekly alcohol consumption was self-reported. Eligible participants were classified as abstainer (never drinker, 42.7%), former drinker (24.4%), consumer of 1-7 drinks (28.5%), or consumer of ≥7 drinks (4.3%). With the exception of 22 participants, all died during follow-up.

Main results


This unique prospective cohort study in community-dwelling older adults with HF, showed that alcohol consumption of ≤7 drinks per week after the diagnosis of HF was associated with longer survival, compared to long-term abstinence. Further research should focus on optimal levels of alcohol consumption in adults with HF and determine whether this differs by age, sex, left ventricular ejection fraction, or cause of HF.
