The effectes of prostaglandin E1(PGE1) on hemo-dynamics, blood gas and metabolism were studiedin 14 patients with severe congestive heart failure, PGE1 was administered intravenously 0.1μg/kg/minfor 60 minutes, Significant hemodynamic effects were obtained within 5 minutes, and persistcd for60 minutes after adnimistration. At peak effect, cardiac index increased from 2.03 L/min//ml to 3.50 L/min/ml (p<0.001), together with significant increase in stroke index and LV work index, mean blood pressure decreased from 109 mmHg to 84 mmHg (p<0.01), systemic vascular resistance index (4,024 to 1,896 dynes・sec・cm-5・M2), mean pulmo-nary capillary wedge pressure (26 to 12 mmHg), mean pulmonary pressure (39 to 23 mmHg), mean right atrial pressure (7 to 4 mmHg), pulmo-nary vascular resistance index 529 to 266 dyes・sec・cm-5・M2) and double product (14,222 to 10,415) decreased significantly, but heart rate remained unchanged. Infusion of PGE1 for 60 minutes resulted in a significant decreae in arteriovenous oxygen difference (6.3 to 4.3 ml/dl), decrease but not significant in arterial oxygen pressure (87 to 77 mmHg), a significant increase in serum angiotensin I, aldosteron and adrenalin level, but no significant change of triglyceride and free fatty acid. PGE1 seemed to be a potent vasodilator with both acting as afterload and preload reduction and to be useful for the treatment of severe heart failure.
