“…In patients with primary pulmonary hypertension, PGI2 acutely decreases pulmonary vascular resistance, increases cardiac output and increases systemic oxygen delivery. 17,20,[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] Elliot et al 30 used nebulized iloprost therapy as early as 8 weeks in pregnancy, with pregnancies completed between 25 and 36 weeks, and with deliveries by caesarean section under local anesthesia without maternal or infant mortality or congenital abnormalities. In patients with congenital heart disease and PAH who failed conventional therapy, long-term, continuous intravenous PGI2 reduced pulmonary artery pressures by 21%, improved cardiac index (69%), pulmonary vascular resistance (52%), and New York Heart Association functional class, but not 6-minute walk distance.…”
