摘　　要：目的:探讨64层螺旋CT冠脉成像中冠脉重构在评价斑块稳定性中的作用。方法:76例临床诊断为冠心病的患者行64层螺旋CT冠状动脉成像。测量相应部位斑块冠状动脉的重构指数和钙化积分,比较急性冠状动脉综合症患者和稳定性心绞痛患者的冠状动脉重构指数:不同钙化积分的冠状动脉重构指数。结果:ACS组患者斑块部位冠状动脉正向重构率为58.1%,SA组正向重构率为24.7%,有统计学意义。ACS与SA的冠状动脉积分有显著性差异。随着冠状动脉钙化积分的升高,正向重构率降低,两者关系有统计学意义。结论:冠脉重构与冠心病的病程密切相关,通过对冠脉斑块和冠脉重构类型的检测,可以评价冠状动脉内斑块的稳定性。Objective： To investigate the coronary remodeling in 64-section MSCTA, to evaluate the role of coronary remodeling in judging the stability of plaque. Methods：76 patients who were diagnosed as of having CAD clinically had undergone 64-MSCT angiography. The reconstitution index of coronary artery, calcification index were obtained. Compare the reconstitution index of coronary artery between ACS and SA, between different calcification index. Results：The rate of positive remodeling in ACS group was 58.1%, while this rate is 24.7% in SA group which demonstrated significant difference between the two groups. The calcification index of coronary artery between ACS and SA has significant difference. With the calcification index of coronary artery increases, the rate of positive remodeling cuts down. Conclusions：Coronary remodeling has a great correlation with CAD in the process of coronary atherosclerosis. 64-section MSCT can evaluate the component of plaque by analyzing the plaque and the type of coronary remodeling.
