- 分析的结果包括无器官支持的日子,机械呼吸,ICU入院和全因死亡率.
主要成果:
- 治疗性肝素对重症COVID-19患者没有益处 (OR 0.83;无效率99.9%).
- 在非危急病患者中,治疗性肝素增加了无器官支持的日子 (OR 1.27).
- RAPID试验显示,治疗性肝素并没有显著降低综合结局,但在非危急病患者中降低了全因死亡率 (OR 0.22).

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

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.
