通过SyncVision/iFR (S-iFR) 引导的皮肤穿透冠状动脉干预 (PCI) 在患有复杂冠状动脉病变的患者中减少了植入的支架长度. 然而,这一策略显示,目标船在一年内故障的数量增加不大.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 医疗技术 医疗技术 医学技术
背景情况:
- 经过皮肤冠状动脉干预 (PCI) 进行的顺序性或扩散性冠状动脉病变患者面临心血管事件风险升高.
- 在PCI方面的技术进步并没有完全减轻这些风险.
- 对复杂冠状动脉病变的新指导策略的有用性需要进一步研究.
研究的目的:
- 为了比较SyncVision/iFR (S-iFR) 引导PCI策略与标准血管造影引导策略的疗效.
- 评估S-iFR指导对植入支架长度和在患有连续性或扩散性冠状动脉病变的患者中一年目标血管衰竭 (TVF) 的影响.
主要方法:
- 一个随机的,多中心的,受控的,开放的标签试验 (NCT04283734) 涉及100名患有顺序性或扩散性冠状动脉狭窄症的患者.
- 患者被随机分配到S-iFR引导的PCI或血管学引导的PCI.
- 主要终点:植入的支架长度;次要终点:一年后的TVF.
主要成果:
- 在S-iFR组显示显著减少了平均植入的支架长度 (32.7毫米对43.1毫米,p=0.002).
- 两组之间没有观察到基线iFR或病变长度的显著差异.
- 一年后的TVF发生在S-iFR组的6.1%,而血管造影组的1.9% (p=0.319).
结论:
- 一个SyncVision/iFR (S-iFR) 引导的PCI策略显著减少了在患有顺序性或长时间扩散冠状动脉病变的患者中植入的支架长度.
- S-iFR策略与目标船在一年内故障的数量增加无关紧要.
- 需要进一步的研究来澄清S-iFR引导PCI在复杂冠状动脉病变中的长期安全性和有效性.
