接受口服抗凝药的心房患者仍然面临中风风险. 诸如AF类型,CHA2DS2-VASc评分和中风史等因素可以确定那些需要进一步的中风预防策略的人.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
背景情况:
- 接受口服抗凝药的心房动 (AF) 患者有缺血性中风和全身栓塞 (SE) 的残留风险.
- 识别高风险个体对于优化中风预防策略至关重要.
研究的目的:
- 在接受口服抗凝药治疗的AF患者中分析残留中风/SE风险.
- 根据CHA2DS2-VASc得分,AF类型和之前的中风史来分层风险.
主要方法:
- 从5个 AF 口服抗凝试验 (COMBINE AF) 中汇集了个体患者的数据.
- 通过CHA2DS2-VASc得分层,AF类型 (帕洛克西斯马尔与非帕洛克西斯马尔) 和中风史计算的中风/SE率.
- 包括71,794名AF患者随机分配给直接服用口服抗凝剂或维生素K对抗剂.
主要成果:
- 整体中风/SE发病率为1.33%/年;非气囊性肌痛动脉 (1.38%/年) 比气囊性肌痛动脉 (1.15%/年) 高.
- 随着CHA2DS2-VASc得分的增加,中风/SE风险增加,在得分≥4.4的情况下达到1.67%/年.
- 患有非发热性AF和CHA2DS2-VASc≥4的患者的风险为1.75%/年;以前患有中风的患者的风险为2.51%/年.
结论:
- AF类型,CHA2DS2-VASc评分和中风史确定了患者具有显著的残留中风/SE风险 (1.5%-2.5%/年),尽管口服抗凝药.
- 对这些高风险患者进行额外的中风/SE预防策略的进一步评估是有必要的.
