Abstract
Objective:To study the characteristic of coronary myocardial bridge related atherosclerotic plaque and explore its relationship with myocardial bridge.Method:A total of 168 cases admitted in the department of cardiology in our hospital were selected as the research objects,they were divided into myocardial bridge group (presence of myocardial bridge in left anterior descending branch and atherosclerotic plaque),plaque group (presence of atherosclerotic plaque in left anterior descending branch only) and control group(normal left anterior descending branch) based on presence or absence of myocardial bridge in left anterior descending branch and atherosclerotic plaque,three groups data were compared.Myocardial bridge group was further subdivided to study the relationship between plaque and myocardial bridge based on the degree of proximal vascular plaque stenosis. Result:34 cases were presented with solitary myocardial bridge and 3,30 and 1 of them were located near the proximal segment of vessels,in the middle segment of the vessels and distal segment of vessels respectively.Within this group,40 atherosclerotic plaques were found with 36,0 and 4 of them located near the proximal segment of vessels,in the middle segment of the vessels and distal segment of vessels respectively.In plaque group 77 cases, 84 atherosclerotic plaques were found,and 55,27 and 2 of them were located near the proximal segment of vessels,in the middle segment of the vessels and distal segment of vessels respectively.There were 57 cases in the control group.There was no significant difference in the basic clinical data in myocardial bridge group and plaque group(P>0.05),there were no significant differences in the patch characteristics,length and stenosis degree of lumen in two groups(P>0.05),but most plaques were found to be located near proximal segment of left anterior descending branch in myocardial bridge group(P<0.05) and an association was found between degree of vascular stenosis near proximal segment with patients’ages(P<0.05),but nothing to do with plaque characteristics and length,length of myocardial bridge and mural coronary types(P>0.05).Conclusion:Vessels complicated with myocardial bridge tend to form atherosclerotic plaques at the proximal segment of vessels under the long-term effects of various risk factors,the degree of luminal stenosis of plaque increased with age,has nothing to do with the plaque and the characteristics of the myocardial bridge.关键词
