Abstract
Two patients with angina pectoris and postmyocardial infarction angina due to coronary vasospasm at the site of myocardial bridge are described. Intracoronary injection of isosorbide dinitrate led to resolution of coronary vasospasm on acetylcholine provocation test, and vasospastic angina pectoris has been well controlled after treatment with calcium channel blockers.
摘要
本文描述了两名因心肌桥部位冠状动脉痉挛导致心绞痛和心肌梗死后心绞痛的患者。冠状动脉内注射硝酸异山梨酯可使乙酰胆碱激发试验中的冠状动脉痉挛缓解，且使用钙通道阻滞剂治疗后，血管痉挛性心绞痛得到了良好控制。
