众所周知,急性冠状动脉综合征(ACS)的病理基础不是管腔的高度狭窄,而是动脉粥样硬化斑块发生破裂、糜烂或斑块内出血等诱发血栓形成,这种易于破损和触发血栓形成的斑块称为易损斑块。易损斑块特点往往表现为薄的纤维帽和大的脂质核心,在斑块与正常血管壁的连接处有炎症细胞浸润 It is well-known that the pathological basis of acute coronary syndrome (ACS) is not the high degree of luminal stenosis, but the atherosclerotic plaque rupture, erosion or plaque hemorrhage induced thrombosis, which is easy to damage and trigger thrombosis Plaque is called vulnerable plaque. Vulnerable plaque characteristics often manifest as thin fibrous cap and large lipid core with inflammatory cell infiltration at the junction of the plaque with the normal vessel wall
