Official Title: Impact of the Pulmonary Index of Microcirculatory Resistance in Pulmonary Arterial Hypertension

Brief Summary: The chief regulator of resistance in pulmonary arterial hypertension (PAH) is the small arteries.In the heart, the invasive measurement of the resistance of the small arteries has been shownto be safe, easy, reliable, and prognostic.This study is intended to translate prior work in heart arteries to the PAH space and invasively measure the resistance of the small arteries of the lung (pulmonary index of microcirculatory resistance [PIMR]) and the coronary artery supplying the right ventricle (acute marginal of the…
