在急性缺血性中风患者中早期与延迟的DOAC启动的评估
1Department of Cardiology, Sanming First Affiliated Hospital of Fujian Medical University, SanMing, China.
概括
在急性缺血性中风 (AIS) 后,对心房动 (AF) 患者早期开始直接口服抗凝剂 (DOAC) 是安全有效的. 三项试验显示早期和延迟的DOAC的结果相似,没有增加出血风险.
科学领域:
- 心脏病学
- 神经学
- 药理学
背景情况:
- 在急性缺血性中风 (AIS) 后的心房患者中,直接口服抗凝剂 (DOAC) 的最佳时间尚不清楚.
- 随机对照试验 (RCT) 的证据对于指导临床实践至关重要.
研究的目的:
- 审查和综合关键RCT (TIMING,ELAN,OPTIMAS) 在AF患者中早期或延迟的DOAC启动的发现.
- 评估早期DOAC启动的安全性和有效性.
主要方法:
- 对三个关键RCT进行分析:TIMING,ELAN和OPTIMAS.
- 早期 (≤4天或根据中风严重程度的特定时间框架) 与延迟的DOAC启动的比较.
- 评估结果包括缺血性中风,全身栓塞和症状性内出血 (ICH).
主要成果:
- 在TIMING和OPTIMAS试验中,早期的DOAC启动 (≤4天) 与延迟的启动无差.
- 没有观察到症状性ICH或复发性缺血事件的显著增加.
- 在ELAN试验中,早期和晚期DOAC组的综合结果相似.
结论:
- 来自TIMING,ELAN和OPTIMAS的综合证据支持在AIS患者中早期启动DOAC的安全性和有效性.
- 早期启动DOAC不会增加症状性ICH的风险,并且在预防复发性缺血事件方面具有可比性.

Acute Coronary Syndrome I: Introduction
71
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
