*Adjusted for age, sex, height, body mass, heart rate, SBP, current smoker, NYHA functional class, LVEF, GNRI, hemoglobin, eGFR, log BNP, and prior heart failure for 6MWD < 300 m and < 400 m.
6MWD, 6-minute walk distance; BNP, B-type natriuretic peptide; % BM, percentage of body mass; CI, confidence intervals; eGFR, estimated glomerular filtration; GNRI, geriatric nutritionl risk index; LVEF; left ventricular ejection fraction; NYHA, New York Heart Association; left ventricular ejection fraction; OR, odds ratio; SBP, systolic blood pressure.
