概括
缓解升级策略 (短期双疗法,随后是DOAC单疗法) 可能会减少接受PCI的心房动患者的出血. 然而,基于华法林的疗法显著增加出血和内出血的风险.
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.
- 临床试验 临床试验
背景情况:
- 针对急性冠状动脉综合征 (ACS) 或冠状动脉疾病 (CAD) 进行皮肤冠状动脉干预 (PCI) 的心房动 (AF) 患者进行抗血栓治疗的管理是复杂的,因为有竞争性出血和缺血风险.
- 五种抗血栓策略进行了比较:降级,VKA三重治疗,VKA双重治疗,DOAC双重治疗和DOAC三重治疗.
研究的目的:
- 在接受PCI的AF患者中比较五种不同的抗血栓策略的疗效和安全性.
- 评估各种治疗方案中全因死亡和出血事件的风险.
主要方法:
- 在主要数据库 (PubMed,Embase,Web of Science,Scopus,CENTRAL) 进行了系统的文献搜索,截至2025年12月20日.
- 进行了7项随机对照试验 (RCT) 的频率主义随机效应网络元分析 (NMA),涉及12,469名参与者.
- 计算了95%置信区间 (CI) 的风险比率 (RR),并使用P-score对治疗进行了排名.
主要成果:
- 与DOAC双重治疗相比,降级疗法显示出潜在的降低出血 (RR 0.50;95% CI 0.30-0.82),尽管由于证据有限,这一发现需要谨慎解释.
- 与DOAC双重治疗相比,华法林与VKA (VKA双重和三重治疗) 显著增加出血风险 (RR 1.33-1.42) 和内出血 (RR 2.95) .
- 两种策略之间在所有死因,心肌梗塞或支架血栓形成方面没有发现显著差异,宽置信区间表明没有统计可检测的差异.
结论:
- 在接受PCI的AF患者中,降级方法 (短时间的双重疗法,然后是DOAC单一疗法) 可能会比DOAC双重疗法提供出血益处,但需要进一步验证.
- 基于华法林的疗法,特别是三重疗法,与增加的出血和内出血有关,突出显示了潜在的安全问题.
- 鉴于缺血性结局的事件率较低,观察到的不同策略的相似性不应被解释为等价性,强调需要仔细选择和监测患者.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

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...
