| 摘 要： | 目的 探讨心肌桥（MB）存在及与冠状动脉粥样硬化（AS）的关系。 方法 回顾性分析在法医尸解中发现的87例心肌桥的形态特点与AS的关系。 结果 MB检出率34.7％，并随年龄呈阶梯样增加，心肌桥主要出现在左冠状动脉前降支及右主干, 单个MB最多，占90.8％（79例）。MB桥前段发生AS有43.7％（38例），管腔狭窄程度大多在Ⅲ级以上占86.8％（33例）；桥后段有8％（7例）发生AS，管腔狭窄程度均在Ⅱ级以下，二者有统计学意义（P<0.05），桥下段无AS；存在AS的MB长度大多2.0cm以上。 结论 大多数MB是解剖变异，随着年龄增加可导致桥前段和桥后段AS，桥前段更易发生AS。

| Abstract: | Objective To investigate the relationship of coronary myocardial bridge(MB) and the coronary atherosclerosis.Methods Pathological changes of coronary artery and morphologic features of MB from autopsy specimens were retrospectively analyzed.Results MB was detected in 87 speciemns from all 251 autopsy cases,especially in aged cases,with the detection rate of 34.7%.MBs were mainly found on the anterior interventricular branch of the left coronary artery and right coronary artery.One bridge was found in 79(90.... |
