January 13, 2021

A study published by the European Society of Cardiology analyzed data from 108,000 people in Sweden, Norway, Finland, Denmark, and Italy from 1982 to 2010. The results found that people who said they drank 12 grams of ethanol a day on average - the equivalent of one small glass of wine or beer - had a 16% increase in their risk of atrial fibrillation over the next 14 years compared with those who said they did not drink at all.
