血小板是高度专门化的循环血细胞,它在正常止血和凝血中起重要作用。因此,在许多情况下它能拯救生命;但它亦能引起血管内膜增厚的病理过程,而在动脉血栓形成时起主要作用。近年来,许多观察表明,动脉粥样硬化与急性心肌梗塞时,血小板寿命缩短,血液中血小板释放的血小板因子4(PF_4),β-血小板球蛋白的水平升高,尤以PF_4升高明显,所以血小板与动脉粥样硬化的关系日益引起人们的重视。
Platelets are highly specialized circulating blood cells that play an important role in normal hemostasis and coagulation. It therefore saves lives in many situations; however, it also causes a pathological process of intimal thickening, which plays a major role in arterial thrombosis. In recent years, many observations show that atherosclerosis and acute myocardial infarction, shortened platelet life, platelet release of blood platelet factor 4 (PF 4), β-thromboglobulin levels, especially in PF 4 increased significantly, Therefore, the relationship between platelets and atherosclerosis has drawn increasing attention.
