NCT ID: NCT01477333

Last Updated: 2023-12-27

Results Overview

Hemodynamics (via right heart catheterization \[RHC\]) were assessed at Baseline and Week 24 or at the time of premature termination of study drug if prior to the Week 24 visit. Cardiopulmonary hemodynamic measurements included the following: mean pulmonary arterial pressure (PAPm), mean systemic arterial pressure (SAPm), mean right atrial pressure (RAPm), and mean pulmonary capillary wedge pressure (PCWPm).
