Physical Exercise and Cardiac Rehabilitation in Chronic Heart Failure: Opportunities, Challenges, and Improvement Strategies

Chronic heart failure (CHF) remains one of the leading causes of morbidity, disability, and mortality worldwide. The primary clinical manifestations of CHF—dyspnea, fatigue, and exercise intolerance—significantly impair patients’ quality of life. Cardiac rehabilitation (CR) effectively improves physical performance, functional status, and compliance in patients with CHF. Conventional CR programs include moderate-intensity aerobic exercise, resistance training, respiratory muscle training, risk factor modification, and patient education. However, engagement in CR remains extremely low. Major barriers include insufficient referrals from healthcare providers, financial constraints, transportation difficulties, and limitations related to social, cognitive, and digital accessibility. This article discusses new strategies for expanding cardiac rehabilitation coverage, including the development of hybrid and home-based programs, the use of digital technology for remote monitoring, and the potential integration of artificial intelligence to personalize treatment approaches. Special attention is given to addressing digital inequality and ensuring broader access to CR programs for vulnerable populations. Innovative cardiac rehabilitation models have the potential to transform the care paradigm for patients with heart failure by increasing access to rehabilitation services and improving clinical outcomes.
