摘要
目的:探讨冠状动脉心肌桥与心肌缺血的关系。方法:回顾性分析接受冠状动脉造影的1 536例患者,共检出心肌桥76例。结果:心肌桥检出率4.3%,心肌桥最常出现在前降支中段,心肌桥近段冠状动脉粥样硬化检出率为18.4%(14/76)。有心肌桥的患者可表现不同程度的心绞痛和心肌梗塞。结论:严重的心肌桥可引起心肌缺血,有症状的心肌桥可首选药物治疗,疗效不佳时可选用介入治疗或外科治疗。
Objective： To investigate the relationship between coronary myocardial bridge and myocardial ischemia. Methods： Among 1536 patients underwent coronary angiography, 76 patients with coronary myocardial bridge were analyzed retrospectively. Results： The total prevalence of myocardial bridges was 4.3 %. Most myocardial bridges are in the left anterior descending branches, and 18.4 % patients with myocardial bridges were concomitant with coronary atherosclerosis in proximal segment. Symptoms of angina pectoris and myocardial infarction were often presented in patients with myocardial bridges. Conclusion：Severe myocardial bridge may result in myocardial ischemia. Pharmacotherapy was the preferred treatment. PCI or operation is another choice when conservative therapy is still not satisfactory.
