Exercise-Based Rehabilitation for Heart Failure: Clinical Evidence

Area of Science:

• Cardiology
• Exercise Physiology
• Rehabilitation Medicine

Background:

• Heart failure (HF) significantly reduces exercise capacity, impacting daily living, quality of life, and increasing mortality.
• Exercise-based cardiac rehabilitation (CR) is proven effective for improving functional capacity and outcomes in patients with heart failure with reduced ejection fraction (HFrEF).
• Current guidelines recommend CR for stable heart failure (HF) patients (Class II-III), including those with HFrEF and heart failure with preserved ejection fraction (HFpEF), though evidence for HFpEF is less robust.

Purpose of the Study:

• To review the clinical evidence on the effects of exercise interventions for patients with HFrEF.
• To review the clinical evidence on the effects of exercise interventions for patients with HFpEF.
• To review the clinical evidence on the effects of exercise interventions for patients with end-stage heart failure.

Main Methods:

• Systematic review of existing cardiac rehabilitation studies.
• Analysis of clinical trial data on exercise training in heart failure populations.
• Separate evaluation of evidence for HFrEF, HFpEF, and end-stage heart failure.

Main Results:

• Exercise training demonstrates significant functional benefits and improved quality of life in HFrEF patients.
• Evidence supports CR as a safe and effective adjunct therapy for stable HF patients across ejection fraction types.
• Data for HFpEF and end-stage heart failure populations indicate potential benefits, warranting further investigation.

Conclusions:

• Exercise-based cardiac rehabilitation is a recommended, evidence-based intervention for improving outcomes in heart failure.
• Continued research is needed to strengthen the evidence base for exercise interventions in HFpEF and end-stage heart failure.
• Personalized exercise prescription within CR programs can optimize benefits for diverse heart failure patient profiles.
