经冠脉CTA，冠脉磁共振(coronary magnetic resonance imaging, coronary MRI), OCT或IVUS等腔内影像，NIRS联合IVUS，可从不同角度观测到贯穿于心脏的各条蜿蜒曲折，宽窄不一的血管成像。若血管外弹力膜（extravascular elastic membrane, EEM）面积介于病变部位近端和远端EEM面积之间，则表示无血管重构。血管重构包括正性重构（positive remodeling）和负性重构（negative remodeling）, 若面积大于病变部位近端和远端EEM的面积，称为血管正性重构，反之当EEM面积小于病变部位近端和远端EEM面积，称为血管负性重构，参数上可通过重构指数，即病变部位EEM面积与近远端EEM面积平均值的比（Remodeling Index，RI）来表示，RI>1.0 表示正性重构， RI<1.0 表示负性重构。
