email article Despite the purported cardiovascular benefits of light drinking, small amounts of alcohol were still linked with incident atrial fibrillation (Afib) in a large observational study. Increased Afib risk was observed with just one daily drink containing 12 g ethanol (HR 1.16, 95% CI 1.11-1.22), whether the beverage was 120 mL of wine (four-fifths of one standard glass), 330 mL of beer (nearly a can's worth), or 40 mL of spirits (roughly one shot), reported Renate Schnabel, MD, of University Heart & Vascular Center Hamburg, Germany, and colleagues. Even very low alcohol consumption, at 2 g per day, was marginally associated with Afib risk over nearly 14 years of follow-up (HR 1.02, 95% CI 1.0-1.04), they wrote in the
