64排VCT-XT检测心肌桥-壁冠状动脉及与冠状动脉硬化相关性的应用

The correlation study between myocardial bridge and atherosclerosis with imaging

目的:通过64排VCT-XT冠状动脉造影(64SCTA)检查,以探讨心肌桥(MB)的长度、厚度与壁冠状动脉(MCA)近端发生粥样硬化间关系及MCA与非MCA近端粥样硬化率是否存在差异性。方法:回顾性分析经64SCTA诊断为MB的44例患者的影像学资料,分析MB长度和厚度与MCA近端发生粥样硬化的关系,分析比较MCA与非MCA近端粥样硬化发生率。结果:44例患者共检出MCA48支、非MCA172支;深在型MCA较浅表型MCA近端更易发生粥样硬化,而与MB长度变化无明显关系;MCA较非MCA更易发生粥样硬化。结论:MB患者的MCA尤其是深在型MCA近端存在着更大的粥样硬化风险,须引起临床足够重视。

Objective：To explore the correlation between the thickness、length of myocardial bridge（MB）and atherosclerosis rate of the mural coronary artery（MCA）.To explore the different atherosclerosis rate of MCA and normal coronary artery（NCA）in same cases.All cases were studied by 64-slice computed tomography（64-SCT）.Methods：Retrospectively analyzed the 64 SCT images of 44 patients with MB.The detection rate was 23 %.We explored the correlation between the Thickness、Length of MB and atherosclerosis rate of MCA and the different atherosclerosis rate of MCA and NCA with the software spss 13.0.Results：48 MCA and 172NCA in 44 cases of MB were detected,The deep type was prone to cause coronary atherosclerosis in the proximal vessels of MB than the superficial one（P0.01）.Length of MB was no influence to atherosclerosis rate of MCA（P0.05）.The MCA was more impossible occur atherosclerosis than NCA in the same cases（P0.01）.Conclusions：The patients with MB,especially the deep types were more impossible occur atherosclerosis,doctor should take more attention.
