RESUMO
Background: Cardiac cachexia (CC) adversely affects the lifestyle of heart failure (HF) patients. The current study examined the impact of melatonin cosupplementation and branched-chain amino acids (BCAAs) on quality of life (QoL), fatigue, and nutritional status in cachectic HF patients. Methods: In this trial, 84 CC patients were randomized to melatonin, BCAAs, or coadministration (both) as intervention groups and a control group over 8 weeks. At baseline and postintervention, QoL, fatigue, and nutritional status were assessed. Results: After intervention, improvement in the overall and physical dimensions of QoL and appetite score were found to be statistically significant in the BCAAs (P < .001) and the melatonin+BCAAs (P < .001) groups compared with the placebo group. The emotional dimension score was significantly lower in the BCAAs group compared with the placebo group (P = .001). There was a statistically significant improvement in fatigue severity in all 3 intervention groups compared with the placebo group. The nutrition risk index (NRI) score increased significantly only in the melatonin group (P = .015), and there was no significant difference between the other groups (P = .804). Conclusions: Cosupplementation with BCAAs and melatonin improved QoL, fatigue status, and appetite in cachectic HF patients but did not affect NRI.
