Model 1: unadjusted; model 2: adjusted for age; model 3: adjusted for age and BMI; model 4: adjusted for factors in model 3 and NYHA class, structure heart disease, hypertension, diabetes, atrial fibrillation, heart rate, atrial pacing, ventricular pacing, LVEF, LAD, LVEDD, and medication at discharge (including ACEI/ARB, beta-blockers, amiodarone, CCB, digitalis, statins, and aspirin).
