Effects of Cardiorespiratory Rehabilitation on the Right Ventricle in Pulmonary Hypertension

Study Overview
=================
Brief Summary
-----------------
Clinical improvement has been demonstrated after cardiorespiratory rehabilitation in patients with pulmonary hypertension. Rehabilitation is therefore now part of the recommendations for good practice. However, no data is available to elucidate the mechanism of this improvement: an improvement in myocardial reserve or an improvement in peripheral muscular capacity? The main objective of this study is to evaluate the difference in right ventricular contractile reserve before and after cardiorespiratory rehabilitation during stress ultrasound in pulmonary hypertension in 10 patients with pulmonary hypertension.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
