Coronary angiography was performed during 34 angina attacks in thirty patients admitted because of recurrent angina at rest. Nineteen (seventeen with S-T segment elevation and two S-T depression) had angiograms during a spontaneous attack, eleven (nine with S-T elevation and two with S-T depression) during an attack induced by intravenous ergonovine maleate. Control coronary angiograms showed a wide range of atherosclerotic obstruction, from normal vessels to severe triple-vessel disease. During the anginal attack, all patients with S-T segment elevation had vasospasm localised to one of the major branches, often resulting in complete occlusion. Attacks with S-T segment depression were seen only in patients with double or triple vessel disease, and here the vasospasm generally affected coronary branches without causing complete occlusion. When appropriately searched for, vasospastic angina seems to be common.
对因静息性复发性心绞痛入院的30例患者在34次心绞痛发作期间进行了冠状动脉造影。19例（17例ST段抬高，2例ST段压低）在自发发作期间进行了血管造影，11例（9例ST段抬高，2例ST段压低）在静脉注射马来酸麦角新碱诱发的发作期间进行了血管造影。对照冠状动脉造影显示动脉粥样硬化阻塞范围广泛，从正常血管到严重的三支血管病变。在心绞痛发作期间，所有ST段抬高的患者均有局限于主要分支之一的血管痉挛，常导致完全闭塞。ST段压低的发作仅见于双支或三支血管病变的患者，此处血管痉挛一般累及冠状动脉分支而不导致完全闭塞。经适当检查，血管痉挛性心绞痛似乎很常见。
