A 66-year-old woman underwent elective cardiac catheterization for investigation of periodic attacks of chest pain at rest. During the examination, a chest pain attack occurred unexpectedly, resulting in ST elevation in the precordial leads on electrocardiography. Immediate coronary arteriography demonstrated no organic stenosis but markedly delayed contrast medium perfusion in the mild to distal portion of the left anterior descending artery. These phenomena spontaneously disappeared about 3 min later, and the patient was diagnosed as having angina pectoris due to microvascular spasm. The demonstration of angina pectoris due to microvascular spasm by coronary arteriography during a spontaneous attack is very rare.
一名66岁女性因静息时周期性胸痛接受选择性心脏导管检查。检查过程中意外发生胸痛发作，心电图显示胸前导联ST段抬高。即时冠状动脉造影显示无器质性狭窄，但左前降支中、远端造影剂灌注明显延迟。这些现象约3分钟后自发消失，该患者被诊断为微血管痉挛所致心绞痛。在自发发作期间通过冠状动脉造影证实微血管痉挛所致心绞痛非常罕见。
