BMI = body mass index. CVD = cardiovascular disease (coronary artery disease, myocardial infarction, angina, CVA, or TIA). DBP = Diastolic blood pressure. HFREF and HFPEF= heart failure with reduced (<50%) and preserved (≥50%) left ventricular ejection fraction, respectively. MI = myocardial infarction. SBP = Systolic blood pressure. Unclassified HF= HF cases in whom left ventricular ejection fraction was unavailable. Data are presented as mean±SD for continuous variables.
