Model 1: unadjusted; model 2: adjusted for age; model 3: adjusted for age and WC; 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). Abbreviations: ACEI = angiotensin-converting enzyme inhibitor; ARB = angiotensin receptor blocker; LVEF = left ventricular ejection fraction; LAD = left atrial dimension; LVEDD = left ventricular end-systolic dimension; NYHA = New York heart association; CCB = calcium channel clockers; WC = waist circumference.
