摘　　要：目的:通过分析确诊心肌桥病人的性别、年龄、心肌桥位置及是否伴有冠状动脉粥样硬化和斑块,探索心肌桥发病的临床特点。方法:收集山东中医药大学第二附属医院与山东省中医院2016年1月1日—2023年3月9日经冠状动脉CT血管造影(CTA)确诊为心肌桥的1617例病人的冠状动脉CTA检查报告,将病人的住院号或门诊号、性别、年龄及冠状动脉强化CT的检查结果导入Excel表格,经Excel计算分析得出心肌桥病人发病的性别比例、平均年龄、各年龄段人数及性别差异、心肌桥的位置特点以及心肌桥伴有冠状动脉狭窄和斑块的比例。结果:1617例确诊心肌桥病人中,男890例,女727例;心肌桥首次检出的平均年龄为60.10岁;心肌桥主要位于左冠状动脉前降支,且主要位于前降支中段;心肌桥病人出现冠状动脉狭窄1142例(70.62%),其中,心肌桥伴相应冠状动脉分支狭窄1073例(66.36%);心肌桥伴有冠状动脉斑块1077例(66.60%),其中,心肌桥伴相应冠状动脉分支出现斑块者1008例(62.34%)。结论:心肌桥的男性患病例数多于女性;心肌桥能够使冠心病症状出现的年龄提前;心肌桥主要发生于左冠状动脉前降支,且主要位于前降支中段;心肌桥常伴有冠状动脉狭窄及斑块的形成,且狭窄及斑块常发生于心肌桥所在的冠状动脉分支近端。Objective:To explore the clinical characteristics of myocardial bridge pathogenesis by analyzing the gender ratio,age,location of myocardial bridge and whether patients with myocardial bridge and coronary atherosclerosis and plaque.Methods:The 1617 patients diagnosed with myocardial bridge by coronary CTA were collected,and the patients'gender,age,and coronary artery enhanced CT examination results were imported into an Excel table.The gender ratio,average age,number of people with different ages and gender differences,location characteristics of myocardial bridge,and proportion of myocardial bridge with coronary artery stenosis and plaque were obtained by Excel calculation and analyzed.Results:Among 1617 patients diagnosed with myocardial bridge,890 were male,and 727 were female;the average age of the first detection of myocardial bridge was 60.10 years old;myocardial bridge mainly located in the left anterior descending branch of the coronary artery,and most of them located at the middle segment of the anterior descending branch.A total of 1142(70.62%)patients with myocardial bridges showed coronary artery stenosis,and a total of 1073(66.36%)patients with myocardial bridges in corresponding coronary artery branches showed stenosis.There were 1077(66.60%)patients with myocardial bridge associated with coronary plaque formation,and 1008(62.34%)patients with plaque associated with corresponding coronary branches.Conclusion:The number of male patients with myocardial bridge was significantly higher than that of female patients.Myocardial bridge may precede the onset of CHD symptoms.Myocardial bridge mainly occurs in the left anterior descending coronary artery,and mainly located in the middle of the anterior descending coronary artery.Myocardial bridging is often accompanied by coronary artery stenosis and plaque formation,and the stenosis and plaques often occur in the proximal part of the coronary artery branch where is the myocardial bridge location.
