摘要(Abstract):
目的研究心肌桥(myocardial bridge,MB)在光学相干断层成像(optical coherence tomography,OCT)中的形态特征以及与动脉硬化的关系。方法对常规冠状动脉造影(coronary angiography,CAG)过程中发现的12例MB患者(男7例,女5例;年龄58.07±12.08岁)进行OCT检查,观察MB的位置、长度以及MB近段2cm血管有无内膜增厚和斑块,并准确测量。结果共发现MB12处,均位于左前降支(LAD)中远段。OCT与CAG测得MB长度对比为20.5±4.2mm比15.6±3.5mm(P<0.01),两者测得最窄处面积狭窄百分率为48.7%±4.8%比55.3%±2.6%(P<0.05)。所有MB段和远段冠状动脉内未发现明显粥样硬化斑块,MB近段2cm内冠状动脉段均发现不同程度内膜增厚(0.64±0.23mm)。结论OCT能清楚显示MB的活体结构及形态特征,操作安全。MB近段冠状动脉内膜均有不同程度增生。
