CTO病变经皮冠状动脉介入治疗(PCI) 在3年随访期内没有显示出心脑血管事件获益,那么行PCI术的意义在哪里?-JAHA:在10年后

冠状动脉慢性完全闭塞病变(CTO)在冠状动脉造影术中是常见的,有研究表明与最佳药物治疗(OMT)相比,CTO病变经皮冠状动脉介入治疗(PCI) 在3年随访期内没有显示出心脑血管事件获益,近期发表于JAHA的一项研究通过长期随访接受PCI与OMT不同治疗策略的CTO患者,发现与OMT治疗策略相比,行PCI治疗可减少CTO患者的晚期心源性死亡的发生

研究共纳入2024例CTO病变的患者,并进行了10年的随访,共排除了接受冠状动脉旁路移植术的CTO患者(n=477),并根据最初的治疗策略将患者分为CTO-PCI组(n=883)或OMT组(n=664)。在CTO-PCI组中,699名患者(79.2%)成功地进行了血运重建。

CTO-PCI组的10年心源性死亡率(10.4% vs 22.3%;HR 0.44,95%CI [0.32-0.59];P<0.001)低于OMT组。

经过倾向评分匹配分析,CTO-PCI组的10年心源性死亡率(13.6% vs 20.8%;HR 0.64,95%CI [0.45-0.91];P=0.01)低于OMT组。

图A 心源性死亡的10年累积事件曲线。

10年心源性死亡率的下降主要是由3年至10年死亡率的下降(8.3% vs 16.6%;HR,0.43, 95%CI,[0.27-0.71;P<0.001) 推动的,尽管前3年死亡率较OMT组是增加的(5.7% vs 5.0%;HR 1.12,95%CI,[0.63-2.00];P=0.71)。

图B 心源性死亡0-3年和3-10年的事件发生时间曲线

结论:CTO-PCI作为一种治疗策略,与标准药物治疗(OMT)策略相比,可减少CTO患者的晚期心源性死亡的发生。
