Key result
Exercise training in patients with congestive heart failure can bring marked peripheral improvement without changing ejection fraction or hemodynamics, although benefits accrue slowly.
Why the study?
Inactivity contributes to the decline of patients with congestive heart failure, and understanding exercise principles in this population is essential.
Does exercise training improve functional capacity in patients with congestive heart failure?
Does exercise training improve functional capacity in patients with congestive heart failure?
Exercise training in CHF patients can improve functional capacity through peripheral adaptations despite no changes in ejection fraction.

May support exercise in HF despite unchanged EF; leaves open optimal duration and outcome impact.
Inactivity adds to the decline of patients with congestive heart failure (CHF). However, in prescribing exercise in these patients, three principles must be understood: ejection fraction does not predict functional capacity, exercise can bring marked peripheral improvement without changing ejection fraction or hemodynamics, and benefits accrue slowly. The authors review the mechanisms of exercise intolerance in CHF and the factors to keep in mind when designing an exercise program.

Braith et al. (1994) conducted a review in Congestive heart failure. Exercise training was evaluated. Exercise training in patients with congestive heart failure can bring marked peripheral improvement without changing ejection fraction or hemodynamics, although benefits accrue slowly.
