AF, atrial fibrillation; BMI, body mass index; CI, confidence interval; SD, standard deviation; HDL-C, high density lipoprotein-cholesterol; HR, hazard ratio; LAD, left atrial dimension.
Multivariable-adjusted HR: age, sex, overweight (BMI ≥25.0 kg/m2), hypertension (systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg and/or present medication for hypertension), current excessive alcohol drinking, current smoking, non-HDL-C, past history of coronary heart disease, valvular heart disease, and the presence of arrhythmia other than AF.
