Abstract
Background: Pulmonary hypertension is a well known poor prognosis indicator. The effects of a rehabilitation program over PH and other right ventricular function measurements are not well established yet. The guidelines recommend pulmonary rehabilitation.The main aim of this study is to assess the effects of a respiratory rehabilitation program over PH, right ventricular function measurements and exercise capacity, assessed by Doppler echocardiography exercise test. Methods: We prospectively include 15 clinically stable patients, with COPD Gold II, III, over one year period. Clinical examination and 1st Doppler echocardiography exercise test (upright bicycle protocol) followed by 2 month pulmonary rehabilitation program and 2nd clinical examination added to Doppler echocardiography exercise test (upright bicycle protocol), were performed to all patients. Heart rate and maximal workload were analyzed in the exercise test. Right atrium pressure and right ventricular to right atrium gradient were measured with Doppler echo technique, tricuspid e and a wave, TAPSE, tricuspid annular, a and s waves were also measured. Results: Conclusions: In this study a respiratory rehabilitation program improved the PH both at rest and at peak exercise as well as exercise capacity.
