Int J Cardiol:冠脉支架治疗后易按照基因型指导抗聚治疗

2016-10-25 MedSci MedSci原创

背景:氯吡格雷有益于急性冠脉综合征和经皮冠状动脉介入治疗的患者。多态性不同,氯吡格雷的反应也不同。本研究的目的是检查CYP2C19 / ABCB1基因指导的治疗策略可降低心血管事件发生率和出血。方法:本实验研究包括接受经皮冠状动脉支架置入术的患者。比较基因型指导策略(干预组)和非量身定制的策略(对照组)。主要疗效终点是干预12个月后因心血管死亡,急性冠脉综合征或脑卒中复合预后。次要终点是比较不同的

背景:氯吡格雷有益于急性冠脉综合征和经皮冠状动脉介入治疗的患者。多态性不同,氯吡格雷的反应也不同。本研究的目的是检查CYP2C19 /ABCB1基因指导的治疗策略可降低心血管事件发生率和出血。

方法:本实验研究包括接受经皮冠状动脉支架置入术的患者。比较基因型指导策略(干预组)和非量身定制的策略(对照组)。主要疗效终点是干预12个月后因心血管死亡,急性冠脉综合征或脑卒中复合预后。次要终点是比较不同的抗血小板治疗的疗效。

结果:这项研究包括进行支架介入治疗的719例患者, 86%以上的患者存在急性冠状动脉综合征。干预组共有32例(10.1%)患者达到主要终点,对照组共有59例(14.1%)达到主要终点(HR 0.63,95% CI(0.41-0.97),P = 0.037)。两组间心肌梗死溶栓发生主要和次要出血无显著差异(4.1% vs. 4.7%,HR = 0.80,95% CI(0.39-1.63),P = 0.55)。在干预组,应用氯吡格雷治疗VS其他抗血小板治疗,复合事件(9.1% vs 11.5%)或出血事件(3.7% vs 4.6%)的发生率没有显著性差异。有事件的发生率与其他抗血小板治疗,或出血与其他抗血小板治疗组患者的事件发生率无显著性差异。

结论:与非基因型指导策略抗聚相比,按照基因型指导策略抗聚的经皮冠状动脉介入治疗的患者,12个月后的复合心血管事件和出血率降低。

EHJ:中国择期PCI患者他汀强化未进一步获益(ISCAP研究)

之前ARMYDA-ACS、ARMYDA-RECAPTURE等研究均显示,择期行经皮冠脉介入治疗(PCI)术前强化他汀与降低围手术期心肌损伤相关。但霍勇等进行的ISCAP研究却表明,择期行PCI的中国患者,与常规他汀治疗相比,连续强化阿托伐他汀治疗并未改善临床转归。研究者认为,ISCAP研究结果与之前研究结果相异,或是因为ISCAP研究入组患者冠脉病变更为复杂严重,多需多血管干预,并且支架长度也较之
