Abstract
Intraarterial and intravenous infusion of prostaglandin E1 (PGE1) is established treatment for severe peripheral arterial occlusive disease, particularly in Europe and Japan. In this critical appraisal, experimental and clinical studies are reviewed, with special emphasis on cardiopulmonary effects and drug safety. The pulmonary data all indicate dose-dependent dilation of the pulmonary vessels with a reduction in pulmonary resistance. The known hemodynamic effects of PGE1 on the heart include an increase in stroke volume, cardiac index, and left ventricular ejection fraction, and a reduction in left ventricular filling pressure. Analysis of clinical trials shows a low rate of adverse effects, in particular a low incidence of cardiopulmonary side effects. If the recommendations for high-risk patients are observed, PGE1 is both an efficacious and safe therapeutic principle.
