概括
与直接口服抗凝剂 (DOAC) 相比,缺血性中风在接受左心房关闭 (LAAC) 预防的心房动患者中不太致残或致命. 这一发现表明,LAAC可能为预防中风提供更好的安全性.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 医疗器械 医疗器械
背景情况:
- 左心房关闭 (LAAC) 预防后的中风通常比华法林中风更轻,因出血性中风较少.
- 直接口服抗凝剂 (DOAC) 也导致罕见的出血性中风,使得缺血性中风 (IS) 成为LAAC和DOAC预防后的主要亚型.
研究的目的:
- 为了比较缺血性中风 (IS) 的严重程度,在心房患者中使用修改的兰金度量表.
- 评估在接受直接口服抗凝剂 (DOAC) 预防与左心房附属器关闭 (LAAC) 预防的患者中IS的结果.
主要方法:
- 一个回顾性分析比较了在LAAC (ISLAAC) 后发展IS的患者与在DOAC治疗期间发展IS的患者 (ISDOAC).
- 评估的主要结局是在医院出院时和事件发生后3个月的致残/致死中风 (修改的兰金尺度3-5).
- 使用倾向性得分匹配和多变量回归分析来调整基线差异,并确定中风严重程度的独立预测因素.
主要成果:
- 与ISDOAC患者相比,经历ISLAAC的患者年龄较大,HAS-BLED得分和先前出血事件较高,但CHA2DS2-VASc得分相似.
- 与ISDOAC组相比,ISLAAC组中脑卒中导致残疾或死亡的频率明显低于ISDOAC组,无论是在出院 (38.3%对70.3%) 或3个月 (33.3%对56.2%).
- 多变量分析证实,ISLAAC独立地与较低的致残/致命中风风险和降低3个月死亡率有关.
结论:
- 在心房患者中发生的缺血性中风在与直接口服抗凝剂 (DOAC) 预防相比,在使用左心房关闭 (LAAC) 预防治疗时,不太可能导致残疾或死亡.
- 这些发现表明,LAAC可能与该患者群体中较为有利的中风严重程度相关.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

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...
