Exercise and heart failure

Area of Science:

• Cardiology
• Exercise Physiology
• Rehabilitation Medicine

Background:

• Chronic heart failure (CHF) significantly impairs exercise tolerance and quality of life.
• Despite optimal therapy, many CHF patients experience debilitating symptoms.
• Systemic pathophysiological changes are linked to exercise limitations in CHF.

Purpose of the Study:

• To discuss factors limiting exercise capacity in CHF.
• To review controlled clinical trials of exercise testing in CHF.
• To explore the role of exercise training in improving outcomes for CHF patients.

Main Methods:

• Review of recent investigations into exercise limitation in CHF.
• Analysis of controlled clinical trials evaluating exercise testing and training.
• Discussion of pathophysiological changes and their correction through exercise.

Main Results:

• Exercise training is safe for carefully selected stable CHF patients.
• Exercise training can correct peripheral pathophysiological changes.
• Improvements in exercise capacity, morbidity, and potentially mortality are associated with exercise training in CHF.

Conclusions:

• Exercise training offers a viable strategy to enhance functional capacity in CHF.
• Addressing pathophysiological factors through exercise training can improve CHF patient outcomes.
• Further research supports exercise training as a component of CHF management.
