Background This study compared the results of exercise Doppler echocardiography (EDE)
with right-sided heart catheterization (RHC) and evaluated the combination of EDE and …

BACKGROUND: Endothelin receptor antagonism has been introduced as an effective oral
therapy of patients with idiopathic pulmonary arterial hypertension. In view of the …

This study investigated the acute pharmacodynamic effects of sildenafil in patients with
pulmonary arterial hypertension (PAH) and concomitant bosentan treatment, in view of a mutual …

Goals of our study were to compare the pulmonary hemodynamics between healthy
