开发和验证DOAC评分:一种新的出血风险预测工具,用于直接作用口服抗凝药的心房患者
在PubMed上查看摘要
概括
此摘要是机器生成的。新的DOAC评分有效估计了服用直接作用口服抗凝剂的心房患者的出血风险,其表现优于HAS-BLED评分. 这种工具有助于个性化抗凝药治疗决策.
科学领域
- 心脏病学
- 药理学
- 临床风险分层
背景情况
- 对于心房患者,现有的出血风险评估工具是不理想的,特别是对于服用直接作用的口服抗凝剂 (DOAC) 患者.
- 这些工具主要是为华法林使用者开发的,限制了它们对现代抗凝治疗的适用性.
- 需要一个验证的风险评分来个性化估计AF患者使用DOACs的风险.
研究的目的
- 开发和验证一种新的临床风险评分,即DOAC评分,用于预测用DOAC治疗的心房患者的严重出血.
- 将DOAC得分与已建立的HAS-BLED得分进行比较.
主要方法
- 使用RE- LY试验的数据,分析了服用达比加的人.
- 该模型在GARFIELD-AF注册中得到进一步改进和验证,包括服用达比加特兰,埃多克萨班,里瓦罗克萨班和阿皮克萨班的患者.
- 使用COMBINE- AF和RAMQ行政数据库进行了外部验证,以评估不同DOAC和人群的通用性.
主要成果
- 在内部验证后,DOAC评分显示出良好的预测性能 (RE-LY的C统计值为0. 73).
- 在所有评估队列 (RE-LY,GARFIELD-AF,COMBINE-AF,RAMQ) 中,DOAC评分显著超过了HAS-BLED评分.
- 在DOAC评分上的每一个额外点都与严重出血风险的大幅增加有关 (48. 7%在RE-LY中).
结论
- 在符合DOAC治疗条件的心房动患者中,DOAC评分是有效分层出血风险的验证工具.
- 与HAS-BLED相比,这种评分提供了更好的风险预测,促进了更个性化的抗凝剂治疗策略.
- 通过DOAC评分,临床医生可以做出关于抗凝药治疗的明智决定.

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...
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history.

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.
