概括
手术前血小板数量较低或较高会增加非心脏手术后主要心血管不良事件 (MACE) 的风险. 这项研究发现血小板水平和MACE之间存在U形关系,这凸显了监测血小板数量的重要性.

- 心血管医学 心血管医学
- 血液学 血液学 血液学
- 外科手术的结果
背景情况:
- 血小板在心血管事件的发病过程中至关重要.
- 手术前的血小板计数是一个常规测量的临床参数.
- 在非心脏手术后,术前血小板计数和主要心血管不良事件 (MACE) 之间的关联尚不清楚.
研究的目的:
- 为了研究异常的手术前血小板计数和非心脏手术后的MACE之间的关系.
- 为了确定血小板缺血或血小板化是否会影响术后心血管结果.

Formation of the Platelet Plug
2.8K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
