[Physical exercise in older patients with chronic heart failure]

Abstract

Maximal exercise capacity undergoes a steady decline after the age of 30 by approximately 10 % per decade. As a consequence of this development older people > 65 years of age suffer from the exercise limitation caused by age-associated cardiac, vascular and skeletal muscle changes. These physiologic alterations make older people especially vulnerable for the cardiovascular and peripheral alterations associated with chronic heart failure (CHF). These changes are not phenomenologically different from age-associated changes. Physical activity plays an important role for regaining a considerable part of vasomotor function, skeletal muscle contractility, and cardiac reserve. Up to now there are no prospective trials comparing the effects of physical training between older and younger patients with CHF. However, smaller observational studies indicate that elderly patients benefit equally well from training interventions with regard to functional improvements in proportion to their lower baseline values. In an aging population training aims at maintaining skeletal muscle force and muscle mass as well as locomotor coordination. Ultimately, the goal is to reduce the substantial morbidity among elderly CHF patients which constitute 79 % of all hospital admissions for heart failure.
