In Situ Measurement of Anti-Apoptotic Phenotype in the Pulmonary Arterial Endothelium and Its Association with Pre-Capillary Disease in Pulmonary Hypertension

Overview

Información sobre este estudio

The purpose of this study is to collect pulmonary arterial endothelial cells from the balloon tips of pulmonary artery catheters (PAC) during right heart catheterization (RHC) and to measure bcl-2 protein expression in these cells in order to index this measurement to a composite hemodynamic and clinical indicators of precapillary vascular disease in pulmonary hypertension.
