摘要：

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64 SCTA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MCA 48支、非MCA 172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。
