Age-related effects of exercise training on diastolic function in heart failure with reduced ejection fraction: the Leipzig Exercise Intervention in Chronic Heart Failure and Aging (LEICA) Diastolic Dysfunction Study.

Abstract

Diastolic dysfunction (DD) was identified as a predictor of adverse prognosis in heart failure with reduced ejection fraction (HFREF). It is, however, unknown if DD is improved by exercise training, which is known to induce reverse remodelling, and if the training effect is attenuated in elderly HFREF patients. We therefore assessed DD in a cohort of referent controls (RCs) and HFREF patients and studied the response of DD to endurance exercise in two age groups (≤55 years and ≥65 years).
