Effect of cyclic intravenous Iloprost therapy in patients with Idiopathic Pulmonary Artery Hypertension

Prostacyclin have positive effects in improving the cardiopulmonary variables, signs and the hemodynamics of cases with a idiopathic pulmonary artery hypertension (IPAH).The objective of this study was to determine the benefits of intermittent intravenous Iloprost infusion on IPAH cases.
Material and This longitudinal study was conducted on IPAH cases (no=20) at Massih Daneshvari Hospital (2011-2013), treated with cyclic intravenous Iloprost. The treatment consisted of a 6 hours/day Iloprost infusion for three consecutive days. Every 6 weeks the infusion was repeated again with a velocity of 0.5-2.0 ng/kg/min. Before, during and after the completion of functional class, six-minute walk test (6MWD), pulmonary artery pressure (PAP), right ventricular pressure (RVP), and plasma NT-ProBNP level were measured.
At follow-up, NYHA score, PAP, RVP, NT-ProBNP and PASP were significantly decreased (P Our results suggest that cyclic intravenous Iloprost might improve the NYHA score, PAP, RVP and can provide a protection against the development or worsening of PAH in patients with IPAH.
