摘要(Abstract)：

目的通过心脏磁共振成像(CMR)结果分析冠状动脉慢性完全闭塞(CTO)病变患者的心肌室壁运动和心肌存活情况及其与CTO血管的对应关系。方法入选2014年12月至2017年11月于北京安贞医院行冠状动脉造影确诊至少有1支血管存在CTO病变的患者128例,入院后均行CMR检查。将左心室划分为17个心肌节段,对每个心肌节段进行室壁运动及延迟强化透壁程度评分,并记录CMR测得的左心室射血分数(LVEF)、收缩末期容积(ESV)、舒张末期容积(EDV)。结果 149支CTO血管供应区域中,仅有11.5%的心肌节段透壁梗死,而58.6%的心肌节段不存在心肌梗死,延迟强化透壁程度≥75%的患者的LVEF最低,EDV及ESV最高。结论 CMR检出大多数CTO患者存在不同程度的室壁运动异常及心肌梗死。透壁性心肌梗死患者存在明显心功能下降及心室重构,但透壁性心肌梗死患者仅占很小一部分。
