Effects of Treprostinil on Right Ventricular Structure and Function in Patients With Pulmonary Arterial Hypertension

Summary

In a group of patients with PAH treated with treprostinil, the current study aims to investigate the effect of treatment on RV structure and function; and correlate changes in RV structure and function with: World Health Organisation (WHO) class, Six-minute walk test, Quality of life (QoL), and Pre-specified biomarkers (N-terminal B-type natriuretic peptide (NT-ProBNP), Tissue growth factor-B B-type natriuretic peptide BNP, and Profibrotic markers)
