Why the study?
The effects of exercise training on left ventricular diastolic function in HFpEF patients have been examined across several randomized clinical trials, but consolidated evidence was needed.
Does exercise training improve exercise capacity and left ventricular function in patients with HFpEF?
Does exercise training improve exercise capacity and left ventricular function in patients with HFpEF?
Exercise training improves exercise capacity in HFpEF patients, though it does not significantly alter left ventricular structure or diastolic function.
Supports exercise training for capacity gains in HFpEF; confirms benefits occur without LV structural or functional changes.
Nearly half of patients with heart failure in the community have heart failure with preserved ejection fraction (HFpEF). Patients with HFpEF are often elderly and their primary chronic symptom is severe exercise intolerance. Left ventricular diastolic dysfunction is associated with the pathophysiology of HFpEF and is an important contributor to exercise intolerance in HFpEF patients. The effects of exercise training on left ventricular diastolic function in HFpEF patients have been examined in several randomised clinical trials. Meta-analysis of the trials indicates that exercise training can provide clinically relevant improvements in exercise capacity without significant change in left ventricular structure or function in HFpEF patients. Further studies are necessary to elucidate the exact mechanisms of exercise intolerance in HFpEF patients and to develop recommendations regarding the most effective type, intensity, frequency, and duration of training in this group.
