The Effects of Exercise on Right Ventricular Contractility and Right Ventricular–Arterial Coupling in Pulmonary Hypertension

Abstract

In contrast to control subjects, patients with PH were unable to increase Ees during submaximal exercise. Failure to compensate for the further increase in Ea during exercise led to deterioration in Ees/Ea. Furthermore, ΔPAP did not reflect ΔEes but rather the change in heart rate.
