Two or more alcoholic drinks a day may increase a woman's risk of atrial fibrillation, reported a study in the December 3, 2008, issue of JAMA. Previous studies showed a high risk of atrial fibrillation among men who were moderate-to-heavy drinkers but not among women. A total of 34,715 women older than age 45 were followed for a median of 12.4 years. Women who consumed two or more drinks each day made up only 3.9% of the group but accounted for about 6.1% of atrial fibrillation. These women had 2.25 atrial fibrillation–related incidents per 1,000 person-years, compared with 1.59 incidents per 1,000 person-years among nondrinkers, or a 1.6-fold greater risk of atrial fibrillation. Researchers found no correlation between atrial fibrillation and consumption of less than two drinks daily.
