PURPOSE: Plasma BNP level is a widely used biomarker to assess disease severity in patients with pulmonary arterial hypertension (PAH). However, the effect of PAH medications on plasma BNP levels is not known. We have observed that many PAH patients on prostacyclin therapy have remarkably low plasma BNP levels despite severely elevated pulmonary arterial (PA) pressure. The purpose of this study, was to determine if prostacyclin treatment lowers plasma BNP levels in PAH patients independent of its effect on pulmonary hemodynamics.
