ABSTRACT

Background: IMT has already been shown to benefit patients with HF; however, it is unclear which patients benefit most from this intervention and what kind of training is most effective. We aimed to review the impact of IMT on respiratory muscle strength, pulmonary function, functional ability, dyspnea, and Qol in HF patients. Method: This systematic review was planned and carried out using the PRISMA guidelines. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched databases. In addition, a thorough search of the references of earlier studies on the subject was carried out. To locate publications published between 2011 and 2024, the search terms "heart failure" and "breathing exercises" were used. Result: we included eight trials totaling 299 patients. Isolated IMT was performed in five trials and contrasted with control groups. Two of these studies included participants with inspiratory muscle weakness. Three trials involved four to six weeks of training during the intervention phase. Three experiments combined IMT with an additional intervention; two of these investigations combined aerobic training and neuromuscular electrical stimulation. One study utilized a load as high as 60% of MIP, while two used loads as high as 30% of inspiratory muscle strength. Conclusion: In patients with respiratory and muscular insufficiency, training loads larger than 60% and longer intervention durations increased inspiratory muscle strength, functional ability, and quality of life more after isolated IMT.
