A Prospective Trial to Evaluate Up-front Parenteral Treprostinil and Riociguat on Right Ventriculo-vascular Coupling and Morphology in Patients With Advanced Pulmonary Arterial Hypertension (IIR-3810)
University of Arizona
Summary
The purpose of this study is to determine if there is a greater effect to patients with advanced pulmonary arterial hypertension (PAH) by using a combination of two drugs, Treprostinil and Riociquat versus Treprostinil alone
Description
The purpose of this study is to evaluate the combined effect of parenteral treprostinil (TRE) and riociguat (RIO) versus parenteral TRE alone on right ventricular (RV)-pulmonary artery (PA) interaction (RVPA coupling) and global RV function in patients with advanced pulmonary arterial hypertension (PAH).
