阿托伐他汀钙和倍他乐克预防心肌桥发作心绞痛症状的临床治疗分析

Prevention of angina pectoris in patients with coronary myocardia bridge by atorvastatin calcium and metoprolol

目的结合心肌桥冠脉造影影像学特征，探讨防治部分心肌桥患者发作心绞痛症状的临床治疗方法。方法对2308例冠状动脉造影术检查中检出的32例心肌桥患者的临床影像学资料进行回顾性分析研究。结果心肌桥的发生率为1．39％，均为位于前降支的单桥，临床诊断孤立性心肌桥13例，并发冠脉粥样硬化15例，高血压病20例。32例心肌桥患者全部有发作性胸病症状。结论冠脉造影术用于心肌桥的诊断可靠，心肌桥在心脏收缩期时可引起心肌缺血的表现，临床应用他汀类、β-受体阻滞剂等药物治疗心肌桥患者是有效的。

Objective To investigate the angiographic features of coronary myocardial bridge （CMB） and the treatment of angina pectoris in patients with coronary myocardia bridge. Methods Thir- ty-two patients with CMB out of 2308 cases underwent selective coronary angiography were studied retro- spectively. Results The incidence of CMB was 1.39%. All of the patients had a single CMB and in- volved the left anterior descending coronary artery （LAD）. Thirteen patients were diagnosed as simple CMB, 15 patients were accompanied with coronary atherosclerosis, 20 patients with hypertension. All the CMB patients had angina pectoris. Medicine such as 13-blocker was effective to treat CMB patients. Con- clusions Selective coronary angiography can be used to diagnose CMB. CMB may cause myocardial is- chemia. CMB patients with symptoms should be treated actively.
