Key result
Exercise training improves exercise tolerance in patients with heart failure, primarily through improvements in peripheral circulation and skeletal muscle structure and function.
Why the study?
Does exercise training improve exercise tolerance in patients with heart failure?
Does exercise training improve exercise tolerance in patients with heart failure?
Exercise training improves exercise tolerance in heart failure patients primarily through peripheral and skeletal muscle adaptations.
Supports exercise training in HF management; leaves open need for RCTs confirming peripheral mechanisms.
Exercise intolerance is present in most patients with left ventricular dysfunction. Factors affecting the central and peripheral circulation, ventilatory system and skeletal muscles limit the exercise capacity in varying degrees within each patient. Exercise training is now being applied with growing enthusiasm to patients with heart failure. Improvements in the peripheral circulation and skeletal muscle structure and function appear to account for the observed benefit in exercise tolerance after training. Exercise programmes in these patients should be initially conducted with close supervision and tailored to the individual patient.

Gary Balady (1998) conducted a review in Heart failure with left ventricular dysfunction. Exercise training was evaluated. Exercise training improves exercise tolerance in patients with heart failure, primarily through improvements in peripheral circulation and skeletal muscle structure and function.
