在接受PCI的心房动 (AF) 患者中,高的克罗皮多格雷尔上血小板反应性 (HPR) 是罕见的. 低血小板反应性是常见的,而ADP诱导的聚合可能有助于确定该人群中的出血风险.
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.
- 血栓形成的原因之一是血栓形成.
背景情况:
- 高的克罗皮多格雷尔上血小板反应性 (HPR) 与皮肤穿冠状动脉干预 (PCI) 后的缺血事件有关.
- 进行PCI的心房动 (AF) 患者通常需要口服抗凝剂 (OAC),使抗血小板治疗管理复杂化.
- 在OAC后PCI的AF患者中评估血小板反应性对于管理缺血和出血风险至关重要.
研究的目的:
- 通过多个电极聚合计 (MEA) 评估的HPR与PCI后AF患者的缺血,血栓栓塞和出血风险之间的关联.
- 为了确定该特定患者队列中HPR和低血小板反应率 (LPR) 的患病率.
- 评估ADP诱导聚合在预测临床结果中的有用性.
主要方法:
- 前性队列研究,包括159名AF患者,PCI后1-3天.
- 使用MEA分析的血小板聚合,将HPR定义为ADP诱导的聚合≥46U和LPR为≤18U.
- 主要结局:综合所有死因,心肌梗塞或中风6个月. 二次结果:发生出血事件.
主要成果:
- 大多数患者 (93%) 显示出整体血小板聚合能力较低,只有1%显示HPR,79%显示LPR.
- 由ADP诱导的聚合与原发性缺血结局没有显著的相关性 (p=0.309).
- ADP诱导的聚合显示出与出血风险的反相关性 (r=-0.201,p=0.011),这表明出血风险评估中的潜在作用.
结论:
- 在接受PCI的AF患者中,HPR不常见,整体血小板聚合能力通常很低.
- 目前的HPR常规切断值可能不适合OAC后PCI的AF患者.
- 由ADP诱导的聚合水平可以作为一种有价值的工具来识别患有更高出血风险的患者.
