Multicenter StudyRelative Importance of Baseline and Longitudinal Evaluation in the Follow-Up of Vasodilator Therapy in Pulmonary Arterial Hypertension.
The aim of this study was to evaluate the relative value of baseline and follow-up echocardiographic assessment of pulmonary artery systolic pressure (PASP) and right ventricular (RV) function in assessing response to vasodilator therapy in pulmonary arterial hypertension (PAH). ⋯ In PAH, baseline RV function (RVFWS) is a strong predictor of outcome, independent of PASP. Changes throughout therapy appear minimal, and only changes in RVFWS, inferior vena cava, size, and right atrial area were associated with outcome.
