临床观察和实验研究结果发现:(1)在动脉粥样硬化(AS)病灶中常可见到血小板性血栓,心肌梗塞猝死患者的冠状动脉中大多有血栓形成;(2)AS的好发部位与血流冲击损伤内皮从而引起血小板聚集部位相一致;(3)AS患者的血小板功能亢进,血浆中血小板第四因子 Clinical observations and experimental studies have found that: (1) thrombotic thrombosis is often seen in atherosclerotic lesions; most of the coronary arteries in patients with sudden myocardial infarction have thrombosis; (2) Flow impact damage to the endothelium resulting in platelet aggregation site consistent; (3) AS patients with hyperthyroidism, plasma platelets in the fourth factor
