NEJM:血管重建术中IFR与FFR的比较

2017-05-11 zhangfan MedSci原创

稳定型心绞痛或急性冠脉综合征患者,IFR引导重建策略与FFR引导重建策略在12个月主要心脏不良事件发生率方面无显著差异

瞬时无波率(IFR)是一种用于评估冠状动脉狭窄严重程度的指标。小规模试验表明瞬时无波率(IFR)与血流储备分数(FFR)有类似的诊断准确性。但IFR的使用缺乏相应的临床研究。近日研究人员比较了IFR与FFR两种方法血管重建后主要心脏不良事件的发生率。

研究招募了2037名稳定型心绞痛或急性冠脉综合征、需要冠状动脉狭窄的生理指导评估患者,随机分配接受IFR或FFR血管重建指导。研究的主要终点是术后12个月内任何原因死亡、非致死性心肌梗死或计划外血管重建的复合发生率。

研究发现,1012名IFR组患者有68名(6.7%)发生主要终点,1007名FFR组患者中,有61名发生(6.1%)主要终点(事件发生率差异,0.7%;95%  [CI],-1.5-2.8;P = 0.007的非劣效性;风险比,1.12;95% CI,0.79-1.58;P = 0.53)。主要亚组间的结果相似。两组患者心肌梗死、靶病变血管重建、再狭窄、支架血栓形成率的差异无统计学意义。研究中FFR组患者发生胸部不适的比例较高。

研究认为,对于稳定型心绞痛或急性冠脉综合征患者,IFR引导重建策略与FFR引导重建策略在12个月主要心脏不良事件发生率方面无显著差异,两种方法效果相近。
