在慢性冠状动脉综合征患者中,复杂的皮肤通冠状动脉干预 (PCI) 会导致更多的心血管事件. 与ALPHEUS试验中的克洛皮多格雷尔相比,提卡格雷罗没有减少这些事件.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 在接受复杂皮肤冠状动脉干预 (PCI) 的慢性冠状动脉综合征患者中,提卡格雷勒在预防心血管事件方面的疗效尚不清楚.
- 复杂的PCI程序对患有慢性冠状动脉综合征的患者带来了独特的挑战和风险.
研究的目的:
- 评估慢性冠状动脉综合征患者复杂PCI的结果.
- 在ALPHEUS试验中,将蒂卡格勒罗与克洛皮多格勒在接受复杂PCI的稳定患者中的疗效进行比较.
主要方法:
- 复杂的PCI是根据特定的标准定义的,包括支架长度,分支支架支架,左侧主干预,旁路移植支架,慢性全闭,切,引导导管延伸使用,多线技术或多个支架.
- 主要终点是PCI后48小时内4a或b型心肌梗塞 (MI) 和主要心肌损伤的组合.
- 复杂性和非复杂性PCI组之间的事件率进行了比较,并分析了PCI复杂性和ticagrelor或clopidogrel之间的治疗相互作用.
主要成果:
- 在1866名随机选择的患者中,近一半 (48.3%) 接受了复杂的PCI.
- 复杂的PCI与主要终点 (45.6%与26.6%) 的显著更高率有关,主要是由于4型心脏病发作和血管学并发症的增加.
- 在复杂的PCI组中,在48小时和30天后观察到较高的复合死亡率,心脏病发作和中风.
- 在PCI复杂性和选择蒂卡格勒罗或克洛皮多格勒之间没有发现显著的相互作用,用于初级或二级终点.
结论:
- 患有慢性冠状动脉综合征并接受复杂PCI的患者经历了周围手术和心血管事件的增加率.
- 在复杂的PCI的背景下,蒂卡格勒罗在减少这些事件方面没有显示出与克洛皮多格勒相比的显著益处.
- 这些发现表明,PCI复杂性是一个显著的风险因素,无论使用的P2Y12抑制剂.
