摘要
目的探讨冠状动脉心肌桥的特征以及临床意义。方法回顾性分析我院2001年10月至2004年5月接受选择性冠脉造影3029例的临床资料。结果在3029例行选择性冠脉造影的人群中,共发现27例冠状动脉心肌桥,发生率为0.89%,心肌桥长度为6～29mm,平均19mm。左前降支有23例(85.2%),左旋支3例,右冠状动脉1例。结论冠状动脉心肌桥多发生于左前降支,可致心肌缺血或心肌梗塞,β受体阻滞剂可缓解所致心绞痛。
Objective To investigate the characteristics and the clinical significance of coronary myocardial bridge(CMB).Methods We retrospective analysis the clinical data and the angiographic results of27patients with CMB.Results We found27patients with CMB in3029patients receiving coronary angiogiography from Oct,2001to May,2004.Positive rate of CMB was0.89%,and usually left descending artery had involved.The average length of CMB was19mm and23CMB in left descending artery,3CMB in left circum artery,1CMB in right coronary artery prospectively.Conclusions CMB is responsible for myocardial ischemia and myocardial infarction.Beta-blocker is effective in symptomatic patients with CMB.
