目的探究心肌桥与壁冠状动脉(MB-MCA)的临床特点和治疗体会。方法 70例MBMCA患者,收集其多层螺旋计算机断层摄影术(MSCT)资料和临床资料,分析与MB-MCA病变相关的因素。结果 MB-MCA合并冠脉硬化39例,孤立性心肌桥-壁冠状动脉31例,MB-MCA合并冠脉硬化在发病年龄、临床症状、患病因素、心脏超声改变和心电图等各方面与孤立性MB-MCA患者相比,差异有统计学意义(P<0.05)。结论 MB-MCA能单独引起心肌缺血的症状,且发生率较高,可以使用MSCT检查诊断。
Objective To investigate the clinical characteristics and treatment of myocardial bridge and wall coronary artery (MB-MCA). Methods Seventy patients with MBMCA were enrolled in this study. The data of multislice spiral computed tomography (MSCT) and clinical data were collected to analyze the related factors of MB-MCA. Results There were 39 cases of MB-MCA complicated with coronary atherosclerosis, 31 cases of solitary myocardial bridge-wall coronary artery, MB-MCA complicated with coronary atherosclerosis in the aspects of age of onset, clinical symptoms, disease factors, echocardiographic changes and electrocardiogram The difference was statistically significant (P <0.05). Conclusion MB-MCA can cause myocardial ischemia alone, and the incidence is high, you can use the MSCT diagnosis.
