Alcohol Consumption Can Raise Risk of Atrial Fibrillation

Alcohol Consumption Can Raise Risk of Atrial Fibrillation

Alcohol consumption can raise risk of atrial fibrillation, according to the latest research. It shows that a single glass of wine can immediately increase the drinker's risk for atrial fibrillation.

A new study by UC San Francisco revealed that alcohol consumption quickly increases the chance of the heart rhythm condition. The authors suggest that reducing or avoiding alcohol might help mitigate harmful effects.

The paper is published August 30, 2021, in Annals of Internal Medicine.

For the findings, the researchers included 100 patients with documented AF who consumed at least one alcoholic drink a month. The investigators recruited these patients from the general cardiology and cardiac electrophysiology outpatient clinics at UCSF.

The study excluded people with a history of alcohol or substance use disorder.

The researchers found an association between atrial fibrillation and with two-fold higher odds with one alcoholic drink as well as three-fold higher odds with two or more drinks. AF episodes also correlated with an increased blood alcohol concentration.

According to Gregory Marcus, even one alcohol drink may be enough to raise the risk. Gregory is MD, MAS, professor of medicine in the Division of Cardiology at UCSF,

"The effects seem to be fairly linear: the more alcohol consumed, the higher the risk of an acute AF event," Marcus said. "These observations mirror what has been reported by patients for decades, but this is the first objective, measurable evidence that a modifiable exposure may acutely influence the chance that an AF episode will occur."
