Data are Hazard Ratios (HR) and 95% confidence intervals (95%CI). HR for continuous variables are per one standard deviation increase. BMI = body mass index; BNP = brain natriuretic peptide; history of arrhythmia intervention = previous pulmonary vein ablation or/and electrical cardioversion. BNP was log-transformed.
