摘要
目的研究心肌桥的临床表现及与血管狭窄关系。方法分析8例心肌桥患者的临床资料。结果均有胸痛史,5例(63%)有心肌缺血征象,1例发生急性前壁心肌梗死。心肌缺血与壁冠状动脉狭窄程度有关。血管狭窄多见左前降支中段,其中Ⅰ级狭窄2例,Ⅱ级狭窄4例,Ⅲ级狭窄2例。β-受体阻滞和血管内支架术治疗有效。结论心肌桥的临床症状与收缩期冠脉狭窄程度有关。严重狭窄可致心肌梗死,β-受体阻滞剂治疗有效,狭窄严重者可行血管内支架术。
Objective To study the clinical features of myocardial bridging and its associations with narrowing of intramural coronary artery. Methods The 8 cases were found by coronary angiography Clinical features and angiographic charac- teristics were analyzed. Results All patients reported to have the history of chest pain. There were 5 cases (63% ) with myocardial ischemia. 1 cases was diagnosed as myocardial infarction. Myocardial ischemia was associations with narrowing degree of intramural coronary artery. 7 cases (88%) were the left anterior descending coronary artery. Ⅰ grade of systolic narrowing were 2 cases. Ⅱ grade were 4 cases, Ⅲ grade were 2 cases. Treatment with β - blockers or coronary artery stent was effective in controlling angina. Condusion clinicdl features of myocardial bridging was associated with systolic narrowing degree of coronary artery , severe systolic narrowness may be able to induce myocardial infarction Trentment β - bockers or coronary artery stent was effecfion.
