Implication
Supports exercise training for chronic HF fatigue; extends peripheral adaptation evidence but leaves optimal protocols open.
Key Points
- To review the pathophysiological mechanisms underlying fatigue and exercise limitation in chronic heart failure, focusing on peripheral musculoskeletal adaptations and therapeutic interventions.
- Synthesized clinical and physiological evidence evaluating peripheral vascular perfusion and skeletal muscle metabolism during physical exertion in chronic heart failure.
- Assessed physiological responses to structured exercise training regimens targeted at reversing peripheral functional impairments.
- Identified impaired peripheral perfusion during exertion, decreased muscle oxidative capacity, reduced muscular strength, and abnormal metabolic reflexes as key contributors to chronic fatigue.
- Demonstrated that structured exercise training partially reverses abnormal peripheral musculoskeletal adaptations, improving peak exercise capacity and relieving fatigue symptoms.

Intervention
Exercise training
Peripheral adaptations contribute significantly to fatigue in chronic heart failure, and exercise training is an effective intervention to mitigate these effects.
