The hemodynamic effects of captopril (50mg), an oral angiotensin-converting enzyme inhibitor, were evaluated in 18 patients with acute myocardial infarction. Eleven patients were in Forrester subset H・1, 4 patients in H・2, 1 patient in H・3, and 2 pa-tients in H・4.

After administration of captopril, cardiac index (CI) rose from 2.81±0.15 (MEAN±1 SEM) 1/min/m2 to 3.07±0.16 1/min/m2, pulmonary diastolic pressure (DPAP) fell from 18.7±1.4 mmHg to 15.3±1.3 mmHg and mean atrial pressure fell from 5.3±0.9 mmHg to 4.0±0.8 mmHg. Systolic blood pressure (122±6 mmHg to 110±5 mmHg), heart rate (89±6 beats/min to 84±5 beats/min), double product (10890±780 mmHg/min to 9380±680 mmHg/min) and total peripheral resistance (2607±262 dyne・sec・cm-5 to 2140±228 dyne・sec・cm-5) fell significantly from control. CI increased with decrease in DPAP in 5 of 6 patients with Forrester subset H・2 and H・4, and in all 7 patients with Forrester subset H・1 whose DPAP was over 14 mmHg.

These findings suggest that captopril is a useful vasodilator in Forrester subset H・2 and also in H・1 who has relatively high DPAP and/or hypertension.
