Researchers Study Possible Links Between Alcohol Consumption and Atrial Fibrillation

Researchers in Boston, Mass., Winston-Salem, N.C., Pittsburgh, Pa., and Baltimore, Md., recently examined the relationship between alcohol consumption and the occurrence of atrial fibrillation in older adults. Past studies have provided mixed results and few conclusions have been made about the role alcohol may play in AF. This study was the first of its kind to research such a relationship, as well as the long-term effects of alcohol consumption on AF and the mortality of AF sufferers who regularly consume alcohol.

Researchers studied more than 5,600 individuals over age 65, who were randomly selected from four U.S. communities. Participants were asked about their alcohol consumption history and were categorized into several groups, including former drinkers (those who drank more than five drinks daily in the past), non-drinkers, those who drink less than one drink per week, those who drink an average of one to six drinks weekly, those who consume 7 to 13 drinks per week, and those who drink more than 14 drinks per week.

Study results revealed that neither the amount nor type of alcohol consumed (beer, wine or liquor) was different among patients with AF and those without it.12 In addition, the amount of alcohol participants consumed did not have an effect on the mortality of AF sufferers.

Individuals with the highest risk of death were individuals with AF in the ‘former drinkers’ category. Researchers clarified that this correlation may be due to previously existing conditions that caused the individuals to reduce their alcohol consumption.

While former drinking habits can identify risk of developing AF, the study does not suggest that individuals with AF need to stop consuming alcohol. Further studies are needed to better understand the full effects or possible benefits of moderate alcohol consumption among AF patients.
