We evaluated the usefulness of clinical application of intracoronary ergonovine for detecting vasospastic angi-na. Intracoronary ergonovine (2, 4, 8μg/min, for 5 min) resulted in occlusive spasm in 10 of 34 patients (7 in 2 μg/min, 2 in 4 μg/min, 1 in 8 μg/min), whereas both intracoronary and additional systemic ergonovine (0.4 mg iv) failed to induce occlusive spasm in 24 of 31 patients. When coronary vasospasticity was expressed as D-ISDN/D-ergonovine (D : diameter of major coro-nary artery) in 12 of 24 patients without occlusive spasm, intracoronary ergonovine (4 and 8 pg/min) was more potent to induce coronary spasm than systemic ergonovine. Ergonovine concentration during intra-coronary administration (4 and S pg/min) in coronary sinus blood was significantly higher than that during systemic ergonovine (0. 4 mg). Since occlusive spasm was produced in 4 of 7 patients with high ergonovine concentration (4 and 8 pg/min), it might be necessary for detecting vasospastic angina to infuse coronary artery with high dose of ergonovine. It was possible to infuse ISDN promptly into the occlueded coronary artery in this study. Thus it was concluded that intracoronary ergonovine was safe and useful procedure for detecting vasospastic angina.
