Therapeutic considerations of sarcopenia in heart failure patients

ABSTRACT

Introduction: Sarcopenia is a common feature, and affects 20–47% of patients with heart failure (HF). Sarcopenia is also an independent predictor of impaired functional capacity, even after adjusting for clinical relevant variables, which is associated with adverse outcome in patients with HF.

Areas covered: Several different pathophysiological pathways are involved in sarcopenic processes including altered nutrient intake and absorption, hormonal factor, inflammatory processes, oxidative stress, cellular proteolysis, and unhealthy lifestyle. Nutritional therapy, physical activity and/or exercise training have been associated with improved muscle mass or physical performance in HF. Few studies reported beneficial effects for muscle mass and physical performance, in those who received angiotensin-converting enzyme (ACE) inhibitors, or/and beta-blocker. In addition, testosterone, selective androgen receptor modulators, ghrelin agonist and myostatin inhibitors are currently under study as possible future therapeutic options.

Expert commentary: Regular and adequate level of physical activity and/or exercise training, and sufficient nutritional intake or special nutritional supplementation may represent the best strategy for prevention or delay of sarcopenia and worsening physical performance in patients with HF. Maximal tolerated dosages of standard therapies for HF such as ACE-inhibitors or beta-blockers are first-line strategy, however it is difficult to recommend other pharmacological agents as part of routine treatment of sarcopenia.
