Exercise-Based Cardiac Rehabilitation for Heart Failure Patients
Summary
Exercise-based cardiac rehabilitation constitutes a cornerstone in the management of patients with heart failure, offering a structured programme of supervised physical activity combined with education and psychosocial support. Predominantly comprising aerobic training, resistance exercises and, in selected cases, high-intensity interval protocols, these interventions target improvements in functional capacity, symptomatic relief and quality of life. Physiologically, regular exercise promotes peripheral adaptations such as enhanced skeletal muscle oxidative capacity and endothelial function, alongside central benefits including modest increases in stroke volume and attenuation of maladaptive neurohormonal activation. Careful patient selection and risk stratification ensure safety, with programmes tailored by New York Heart Association class, comorbidities and device therapies. Beyond traditional centre-based models, home- and tele-rehabilitation platforms are expanding access, addressing geographical and socioeconomic barriers. Despite robust evidence of reductions in hospital admissions and all-cause mortality, uptake remains suboptimal worldwide. Multidisciplinary collaboration among cardiologists, physiotherapists and allied health professionals underpins optimal delivery, while ongoing innovation seeks to personalise intensity, integrate behavioural strategies and extend long-term adherence.

Exercise-Based Cardiac Rehabilitation for Heart Failure Patients publication trend
The graph below shows the total number of articles in exercise-based cardiac rehabilitation for heart failure patients across all publications each year (not limited to Nature Index journals).
Technical terms
Heart failure: A syndrome in which the heart is unable to pump sufficiently to meet the body’s demands, resulting in symptoms such as breathlessness and fatigue.
Cardiac rehabilitation: A multidisciplinary programme combining supervised exercise, education and psychosocial support to improve cardiovascular health after cardiac events or in chronic disease.
Peak oxygen uptake (peak VO₂): The maximal rate of oxygen consumption measured during incremental exercise, reflecting aerobic capacity.
Left ventricular ejection fraction (LVEF): The percentage of blood ejected from the left ventricle with each heartbeat, used to assess systolic function.
Cardiac resynchronization therapy (CRT): A device-based treatment that coordinates the timing of ventricular contractions to improve heart function in selected heart failure patients.
Exercise self-efficacy (ESE): An individual’s belief in their ability to undertake and adhere to exercise regimens, influenced by psychological and environmental factors.
