Pulmonary Hypertension Clinical Trial
Official title:
Effect of Endothelin-1 Receptor Blockade on Circulating Endothelial Microparticles Levels in Patients With Pulmonary Hypertension
Pulmonary hypertension is a progressive and life threatening condition. It is characterized
by severe remodeling of the pulmonary vessel wall, obstructive plexiform lesions,
multi-focal thrombosis, and enhanced vasoconstriction. All of these characteristics
contribute to increased pulmonary vascular resistance.
Circulating endothelial microparticles (EMPs) play an integral role in the pathogenesis and
perpetuation of pulmonary hypertension. Levels of EMPs are considered a reliable biological
parameter of endothelial injury.
We propose to assess the evolution of both circulating and pulmonary venous EMPs in patients
with PH. Assessments will be made before and after initiation of Endothelin-1 (ET-1)
Receptor blocker therapy, and correlated to their patterns with the changes in mean PAP, the
6 Minutes Walking Distance test, and circulating Endothelin-1 values. Measurements of the
endothelial microparticle circulating levels (assessed by flow cytometry methods) will be
made before, 1 month and 3 months after initiation of therapy.
