Neuromuscular electrical stimulation (NMES) seems to be safe and beneficial in improvement in functional capacity, muscle strength, and quality of life when compared with conventional aerobic exercise, while the change in muscle fiber composition and muscle size was conflicting in patients with heart failure (HF). Moreover, NMES studies seem to have beneficial effects on pro-inflammatory cytokine, oxidative enzyme activity, and protein anabolic and catabolic metabolism that are the key molecular mechanism of muscle wasting in patients with HF. We review specific issues related to the effects of NMES on muscle wasting in patients with HF, whether NMES seems to be an alternative exercise modality preventing or improving in muscle wasting for HF patients who are unable or unwilling to engage in conventional exercise training; however no established strategies currently exist to focus on the patients with HF accompanied by muscle wasting.
