Right Ventricular Phenotyping Can Lead to Pulmonary Vascular Therapy Response in Those with Pulmonary Hypertension with COPD: A Single-Center Cohort Study.

Abstract

Pulmonary hypertension (PH) with chronic obstructive pulmonary disease (COPD) is associated with poor survival with no approved therapies. We report on the response to inhaled treprostinil (iTRE) of a small retrospective cohort of PH-COPD patients with a baseline "PH-right ventricular (RV) phenotype", defined by a RV-dependent circulatory limitation derived from a combination of echocardiographic and hemodynamic criteria. Patients were started on inhaled treprostinil with significant improvement in six-minute walk distance, NT-proBNP, and improved RV metrics by echocardiography. The preliminary findings of this cohort provide evidence for the importance of precision phenotyping of PH-COPD.
