摘要：

目的　探讨冠状动脉重塑类型与心绞痛临床特点的关系。方法　对 49例急性冠状动脉综合征 (ACS)和 2 6例稳定型心绞痛 (SA)患者的“罪犯”病变进行血管内超声检查。重塑指数定义为病变处血管面积与病变近端参照部位血管面积的比值 ,如重塑指数 >1.1为代偿性重塑 ,重塑指数 <0 .9为收缩性重塑 ,重塑指数在 0 .9与 1.1之间为无重塑。斑块回声强度低于血管外膜回声者为软斑块。结果　软斑块在ACS组与SA组间差异无显著性意义 (ACS组 5 9% ,SA组 46% ,P >0 .0 5 )。ACS患者代偿性重塑明显高于SA组 (ACS组 49% ,SA组 12 % ,P <0 .0 1) ,而SA患者收缩性重塑明显高于ACS组 (ACS组 3 1% ,SA组69 % ,P <0 .0 1)。结论　应用血管内超声成像技术评价冠状动脉重塑 ,同斑块的性质相比 ,与心绞痛的临床特点更为密切相关。
