The aim of the present study was to determine whether the addition of an oral nutritional supplement with whey peptides and branched-chain amino acids for cardiac rehabilitation improves cardiopulmonary function, skeletal muscle function, and metabolism in CHF patients.In this randomized, parallel-group comparative pilot study, 20 CHF patients were randomly assigned to the nutrition group (n = 10) or the control group (n = 10). At baseline and 12 weeks, we performed physical examinations, motor function evaluation, clinical laboratory tests, nutritional status assessment, and echocardiography. The primary outcome was exercise tolerance, as determined by the cardiopulmonary stress test (CPX), 6-minute walking test (6MWT), and brain natriuretic peptide (BNP) levels.During follow-up, body weight, body mass index, total muscle mass, and total lean mass did not change significantly in either group. The total fat mass significantly increased in the nutrition group (14.3 ± 5.4 kg versus 16.1 ± 5.5 kg, P < 0.001) but did not change in the control group, and the difference in the changes in total fat mass between groups was significant (−0.26 ± 0.96 kg versus 1.49 ± 0.63 kg, P < 0.001). The peakVO2 and 6-minute walk test (6 MWT) significantly increased in the nutrition group (14.6 ± 3.4 mL/minute/kg versus 15.8 ± 3.8 mL/minute/kg, P = 0.029; 346.9 ± 103.1 m versus 382.7 ± 102.1 m, P = 0.048; respectively) but did not change in the control group. The changes in peakVO2 and 6MWT did not significantly differ between the groups.The oral nutritional supplement for the treatment of CHF was effective for cardiac rehabilitation in terms of fat mass and exercise capacity.The present study demonstrated that oral nutritional supplements with whey peptides and branched-chain amino acid (BCAA) for cardiac rehabilitation in patients with chronic heart failure (CHF) increased fat mass and exercise capacity. We conclude that whey peptides and BCAA supplementation may be a useful treatment for CHF patients.
