Abstract

The cardiocirculatory actions of brief (69 ± 5 minutes) infusions of prostaglandin E1 were evaluated in nine chronic coronary heart disease patients with severe left ventricular (LV) failure caused by previous myocardial infarction. Prostaglandin E1 infusion did not alter heart rate (HR) and produced modest declines in mean systemic blood pressure (BP) (85 ± 6 to 76 ± 5 mm Hg, p < 0.025) and LV filling pressure (19 ± 3 to 15 ± 2 mm Hg, p < 0.01). Simultaneously, prostaglandin E1 augmented LV pump function raising cardiac index from 1.9 ± 0.2 to 2.5 ± 0.2 L/min/m2 (p < 0.005), elevating stroke index from 28 ± 2.4 to 35 ± 2.9 ml/beat/m2 (p < 0.01), and increasing stroke work index from 26 ± 4.3 to 30 ± 4.4 gm·m/m2 (p < 0.02). Additionally, total systemic vascular resistance decreased from 1862 ± 192 to 1282 ± 100 dynes-sec-cm-5 (p < 0.02) and double product LV aerobic index of HR · systolic BP diminished from 9492 ± 666 to 8278 ± 493 (p < 0.02). Concomitantly, in the forearm, vascular resistance fell, blood flow rose, and venous tone remained unchanged. These results indicate that prostaglandin E1 is a potent systemic arteriolar dilator with markedly beneficial effects on cardiac function in chronic coronary patients having severe ischemic LV failure refractory to conventional therapy.
