ALDH2 and atrial fibrillation: After considering the daily alcohol consumption and the presence of ALDH2 polymorphism, the phasic LA parameters of the reservoir and booster pump functions (adjusted OR: 1.76 (95% CI: 1.01–3.07), p = 0.046 and 1.68 (95% CI: 1.06–2.67), p = 0.028 per 1 standardized unit increment) remained independent indicators in AF after the CHARGE-AF score adjustments (Figure 4B).
