Model 1: Unadjusted. Model 2: Adjusted age, cigarette smoking, serum low‐density lipoprotein cholesterol, systolic blood pressure, type 2 diabetes, body mass index, previous myocardial infarction, family history of coronary heart disease, and cardiorespiratory fitness. Model 3: Model 2 plus left ventricular function. Model 4: Model 3 plus time‐varying incident coronary events. BSA indicates body surface area; HR, hazard ratio; LV, left ventricular; Q1 to Q4, quartiles from 1 to 4.
