血栓形成三要素（动脉血栓）
三要素高凝状态内涵慢性阶段：炎性病变、凝血活化、纤维蛋白原增高、vWF增高、血小板活化急性阶段：动脉斑块破裂，组织因子释放血管壁损伤血流动力异常炎性病变、胶原堆积受损的内皮细胞表面基质崩解心肌细胞坏死、心肌肥大、左房膨胀心房排空受损、左房血流瘀滞红细胞-促凝因子间反应Scanning electron microscopy of intracoronary thrombi from STEMI patients showed that
thrombus composition evolves over time during the acute phase of MI and fibrin content
increased from 48.4% in thrombi collected <3 hours from symptom onset to 66.9% in those collected after 6 hours (h), whereas platelet content decreased from 24.9% to 9.1% .
