How much is too much? Even moderate alcohol consumption is a risk factor for atrial fibrillation

(Elsevier) Excessive alcohol consumption is an established risk factor for atrial fibrillation (AF), but what are the effects of moderate and mild consumption on AF? In a new study published in HeartRhythm Australian researchers showed that regular moderate alcohol consumption (an average of 14 glasses per week) results in more electrical evidence of scarring and impairments in electrical signaling compared with non-drinkers and light drinkers. Alcohol consumption is therefore an important modifiable risk factor for AF.
