A 53-year-old woman was admitted with unstable angina. Acute coronary angiography showed myocardial bridging and total occlusion of the left anterior descending artery in the middle one-third of its course. The occlusion was completely relieved by intracoronary administration of nitroglycerin. The occurrence of coronary spasm may explain angina and myocardial infarction in symptomatic patients with myocardial bridges.
一名53岁女性因不稳定型心绞痛入院。急性冠状动脉造影显示心肌桥以及左前降支在其中段三分之一行程处完全闭塞。通过冠状动脉内给予硝酸甘油，闭塞完全缓解。冠状动脉痉挛的发生可能解释了有症状的心肌桥患者出现心绞痛和心肌梗死的原因。
