Hazard ratios (HR) reported per 1 standard deviation increase in sphericity index.
BMI = body mass index, HTN = hypertension, DM = diabetes mellitus, MI = myocardial infarction, LVEF = left ventricular ejection fraction, LVEDVi = left ventricular end-diastolic volume indexed on body surface area, LVESVi = left ventricular end-systolic volume indexed on body surface area
