Model 1, crude; Model 2, adjustment for sex and age; Model 3, full-adjustment model [adjustment for age, smoking, sex gender, hypertension (HTN), estimating glomerular filtration rate (eGFR), coronary artery disease (CAD), diabetes mellitus (DM), early recurrence (ER), body mass index (BMI), left atrial dimension (LAD), and left ventricular ejection fraction (LVEF)].
