概括
当前用于预测直接口服抗凝剂 (DOAC) 用户胃肠道出血 (GIB) 的风险评分,当患者同时接受抗血小板治疗时,其准确性较低. 未来的模型需要纳入抗血小板使用,以改善GIB预测.
科学领域:
- 心脏病学 心脏病学
- 药理学 药理学是指药理学的学科.
- 临床医学 临床医学
背景情况:
- 直接口服抗凝剂 (DOAC) 广泛用于抗凝.
- 胃肠道出血 (GIB) 是与DOACs相关的重大不良事件.
- 准确预测GIB风险对于患者安全至关重要.
研究的目的:
- 评估四种已建立的风险评分模型 (HAS-BLED,ATRIA,VTE-BLEED,ORBIT) 在预测GIB方面的有效性.
- 评估同时使用抗血小板治疗如何影响这些模型在DOAC用户中的预测性能.
主要方法:
- 在2014年12月至2020年10月期间,一项对4494名患者进行的回顾性研究规定了DOAC.
- 四个GIB风险评分模型的预测性能 (AUROC,概率比) 的比较.
- 基于同时使用抗血小板治疗的分析分层.
主要成果:
- 这四种模型 (HAS-BLED,ATRIA,VTE-BLEED,ORBIT) 都显示出中等的预测性能 (AUROC范围:0.643-0.709).
- 预测准确度,特异性和AUROC值在接受抗血小板治疗的患者*没有*的所有模型中都显著更高.
- 在DOAC使用者也服用抗血小板剂的小组中,表现下降.
结论:
- 现有的DOAC使用者的GIB风险评分模型显示,当同时使用抗血小板治疗时,其准确性降低.
- 这些发现突出了当前GIB风险分层工具的关键局限性.
- 未来的DOAC相关GIB风险预测模型应该整合抗血小板治疗状态,以提高诊断准确度.

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...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
