| الوصف: | To evaluate the effects of prostacyclin (prostaglandin I2) on pulmonary vascular tone in primary pulmonary hypertension (PPH), we performed right-heart catheterization on seven patients with PPH and made hemodynamic measurements before and after infusing incremental doses of prostacyclin. In maximal doses of 2-12 mg/kg/min (mean 5.7 +/0 3.1 ng/kg/min), prostacyclin reduced mean pulmonary arterial pressure from 62 +/- 15 to 55 +/- 16 mm Hg (p less than 0.05) and total pulmonary resistance from 17.1 +/- 8.7 to 9.7 +/- 5.9 units (p less than 0.005), and increased cardiac output from 4.22 +/- 1.64 to 6.57 +/- 2.04 l/min (p less than 0.01). Heart rate increased from 83 +/- 13 to 94 +/- 11 beats/min (p = 0.1) and mean systemic arterial pressure decreased from 90 +/- 12 to 77 +/- 4 mm Hg (p = 0.055). Three patients who received a continuous infusion of prostacyclin for 24-48 hours had sustained reductions in total pulmonary resistance during the infusion period. These data demonstrate that prostacyclin can increase cardiac output and reduce pulmonary arterial pressure and resistance in PPH. |
