摘要(Abstract)：

目的评价急性心肌梗死(AMI)患者直接介入治疗术后发生慢血流现象的梗死相关动脉(IRA)的病变特征。方法 18例AMI患者的IRA介入术前进行血管内超声(IVUS)检查,对梗死相关动脉置入冠脉支架治疗,根据TIMI帧数方法对术后血流进行评价,分成慢血流组(6例)和正常血流组(12例)。分析慢血流组和正常血流组的IRA外弹力膜-最小管腔面积(EEM-CSA)、最小管腔面积、面积狭窄、斑块负荷、平均斑块面积、斑块容积等指标。结果慢血流组EEM-CSA、平均斑块面积、斑块容积高于正常血流组,分别是(20.90±6.38)mm2比(14.87±4.50)mm2,P=0.033;(12.95±3.06)mm2比(9.21±3.35)mm2,P=0.045;(450.89±120.65)mm3比(199.08±83.53)mm3,P=0.0001。结论 AMI患者IRA介入术后慢血流与介入术前的靶病变斑块面积、斑块容量以及EEM-CSA有关,斑块面积和容量越大介入术后发生慢血流的概率越大,血管面积较大发生慢血流的概率亦较大。
