Abstract
Cardiovascular diseases pose a serious problem for health globally. Among these, congestive heart failure is the leading cause of mortality and morbidity worldwide. According to the recent census, heart failure contributes to a huge financial burden annually. Exercise therapy is an integral part of the non-pharmacological management of heart failure. Due to the availability of various types of exercise therapies and rapid advancements in the existing evidence, it is often challenging to prescribe an appropriate exercise program. Although there is unequivocal evidence supporting the cardiovascular benefits of aerobic therapy, the incorporation of resistance training into exercise regimens should also be encouraged due to its effects on muscular endurance and ameliorating skeletal myopathy in heart failure. In this study, we used a systematic literature review (SLR) approach to give an overview of the current literature and highlight the cardiovascular benefits of resistance training, alone or in combination with aerobic training. We reviewed articles from well-recognized journals published between 2013 and 2023, finally narrowing down to nine selected papers for a thorough analysis. The inclusion criteria comprise studies dealing with heart failure with reduced ejection fraction (HFrEF), resistance training alone or in combination with aerobic therapy, and studies available for free in either the PubMed or Google Scholar databases. The systematic review revealed that resistance training in combination with aerobic therapy has greater cardiovascular benefits than either resistance or aerobic therapy alone. A few unique approaches, like periodic intermittent muscular exercise (PRIME) and super circuit training (SCT), have demonstrated an improvement in cardiac and non-cardiac clinical outcomes compared to conventional exercise therapies. Moreover, various factors, like lack of motivation and lack of time, contribute to poor adherence to exercise therapy. Approaches like telerehabilitation and designing exercise regimens with activities that patients enjoy have led to improvements in long-term adherence rates. Nevertheless, further exploration and research by conducting randomized controlled trials on a larger scale is essential to explore the potential of resistance training in the rehabilitation of patients with heart failure with reduced ejection fraction and to develop the most effective exercise therapy.
