After adjustment for multiple cofounders, those who drank daily had a 2.6 times greater risk of being in the atrial-fibrillation and atrial-flutter cohort. After researchers controlled for the same confounders, the increased risk remained significant in subjects <60 years of age when they compared atrial-fibrillation and -flutter subjects without arrhythmia but only trended toward significance when compared with SVT patients alone.
When investigators examined the progressive risk of atrial fibrillation and flutter with different amounts of alcohol consumed, there was a trend toward greater risk with more alcohol consumed. Drinking more and more alcohol, on the other hand, was significantly associated with an increased risk of atrial flutter.
"Even at the recommended one to two drinks per day," Marcus told heartwire, "there was an increased and significant risk for atrial flutter."
While alcohol in limited amounts is known to be cardioprotective, many patients with atrial fibrillation might be under the impression that they should be drinking one or two drinks per day, said Marcus. "But I think we need to study this further, especially in atrial-fibrillation patients." he said. "My message would be that they should try to avoid alcohol, and not just binge drinking but also daily consumption, until we know better."
