Early Recovery of Oxygen Kinetics After Submaximal Exercise Test Predicts Functional Capacity in Patients with Chronic Heart Failure

Abstract

Early recovery O2 kinetics parameters after maximal and submaximal exercise correlate closely with established indices of exercise capacity in patients with CHF and in healthy volunteers. These findings support the use of early recovery O2 kinetics after submaximal exercise testing as an index of functional capacity in patients with CHF.
