One alcoholic drink per day can increase risk of atrial fibrillation: Study ANI | Updated: Jan 23, 2021 16:53 IST Washington [US], January 23 (ANI): A recent study revealed that individuals who regularly drink a humble measure of liquor are at a higher risk of atrial fibrillation, a condition where the heart pulsates in a strange rhythm. The study, published in the European Heart Journal found that, compared to drinking no alcohol at all, just one alcoholic drink a day was linked to a 16 per cent increased risk of atrial fibrillation over an average (median) follow-up time of nearly 14 years. This means that while four teetotallers in 100 might develop atrial fibrillation over the period of the study, five per 100 might develop the condition if they consumed alcohol starting with slightly more than an alcoholic drink a week and more than 75 per cent of them consumed up to one drink a day.
