What is the impact of alcohol consumption on the risk of atrial fibrillation?
Several studies have been conducted to evaluate the impact of alcohol consumption on the risk of atrial fibrillation. A meta-analysis of seven studies conducted by Kodama et al. (2011) found that the risk of atrial fibrillation was significantly increased with heavy alcohol consumption (≥30 g/day). A systematic review and meta-analysis conducted by Samokhvalov et al. (2010) found that the risk of atrial fibrillation was significantly increased with moderate alcohol consumption (10–20 g/day). In addition, a meta-analysis of six studies conducted by Liang et al. (2012) found that the risk of atrial fibrillation was significantly increased with moderate alcohol consumption (11–19 g/day). Therefore, it can be concluded that alcohol consumption can significantly increase the risk of atrial fibrillation.
