目的:探讨心肌桥的影像特征及临床治疗方法。方法:回顾性分析317例冠状动脉(冠脉)造影中检出的11例心肌桥患者的临床资料。结果:心肌桥发生率为3.5%,其中单桥10例,均位于前降支;双桥1例,位于前降支及回旋支。临床诊断孤立性心肌桥6例,并发冠脉粥样硬化3例,并发高血压4例。11例心肌桥患者中10例有发作性胸痛症状,另1例有心律失常,经治疗后胸痛患者症状明显缓解,心律失常者恢复正常。结论:选择性冠脉造影可用于心肌桥的诊断,心肌桥可能引起心肌缺血表现,应用β受体阻滞剂等药物或支架置入术治疗心肌桥患者有效。
Objective: To investigate the imaging characteristics and clinical treatment of myocardial bridge. Methods: A retrospective analysis of 317 cases of coronary artery (coronary angiography) detected in 11 cases of myocardial bridge clinical data. Results: The incidence of myocardial bridge was 3.5%, including 10 cases of single bridge, all located in the anterior descending branch; 1 case of double bridge, located in the anterior descending branch and the circumflex branch. 6 cases of isolated myocardial bridge were diagnosed clinically, 3 cases were complicated with coronary atherosclerosis and 4 cases were complicated with hypertension. Among the 11 patients with myocardial bridge, 10 had episodes of chest pain and the other had arrhythmia. The symptoms of chest pain were relieved and the arrhythmia returned to normal after treatment. CONCLUSION: Selective coronary angiography can be used to diagnose myocardial bridge. Myocardial bridge may cause myocardial ischemia. The application of β-blockers and other drugs or stent implantation in patients with myocardial bridge is effective.
