荷兰Catharina Hospital Eindhoven心内科的Zimmermann FM等人研究了冠脉未显著狭窄的患者,延迟PCI手术与早期行PCI手术,两者远期预后结局的差异,其成果发表在9月份 European heart journal期刊上。

目的:在狭窄不显著的冠脉中植入支架仍受争议。对血流储备分数(FFR)上显示无显著意义损伤的患者延迟PCI术的安全性抱有怀疑,尤其是远期效益。DEFE试验(五年随访)结果表明:基于FFR≥0.75中度冠脉狭窄患者,延迟经皮冠状动脉介入治疗(PCI)有更好的结局,早期植入支架并无明显改善。此项研究的目的旨在探索这种情况的远期有效性。

方法和结果:研究纳入325例中度冠脉狭窄患者(预行PCI术),介入术前测量FFR值。如果FFR≥0.75,将患者随机分配到两组:延迟PCI术组(延期组;n=91)和行PCI术组(执行组;n= 90)。如果FFR<0.75,行PCI术(参照组; N=144)。临床随访15年。各随机组之间的基线临床特征无显著差异。92%患者进行了15年随访。15年随访后,三组之间的死亡率有所不同:延迟组为33.0%,执行组为31.1%,参照组为36.1%(延迟组vs.执行组,RR=1.06, 95%CI:0.69-1.62,P =0.79)。延迟组心肌梗死率(2.2%)与执行组心肌梗死率(10.0%)相比显著降低,RR=0.22,95%CI:0.05-0.99,P = 0.03。

结局:在功能上未显著狭窄的患者延迟行PCI术对长期预后更有利。
