JAMA :血管内超声指导下行药物涂层支架植入会更安全

2015-11-11 Mechront 译 MedSci原创

对复杂冠状动脉病变进行冠状动脉介入时,使用血管内超声显像 (IVUS) 可以得到更好的临床结局。不过有数据表明,当使用药物洗脱支架治疗时,IVUS的临床应用就会受到限制。研究者进行了一项研究,探究长冠状动脉病变(植入支架长度 ≥28 mm)患者进行药物洗脱支架植入时,通过IVUS能否更优于血管造影术。该随机多中心研究纳入了1400名患者,使用依维莫司涂层支架植入时,随机使用IVUS(n=700)或

对复杂冠状动脉病变进行冠状动脉介入时,使用血管内超声显像 (IVUS) 可以得到更好的临床结局。不过有数据表明,当使用药物洗脱支架治疗时,IVUS的临床应用就会受到限制。

研究者进行了一项研究,探究长段冠状动脉病变(植入支架长度 ≥28 mm)患者进行药物洗脱支架植入时,通过IVUS能否更优于血管造影术。

该随机多中心研究纳入了1400名患者,使用依维莫司涂层支架植入时,随机使用IVUS(n=700)或血管造影术(n=700)。

初始结局指标为主要的不良心脏事件,包括心脏死亡、靶病变相关的心肌梗死、靶病变血管重建导致的缺血。

共有1323名 (94.5%)患者完成了为期1年的随访。IVUS组和血管造影组分为有19名(2.9%)患者和39名 (5.8%)患者发生不良心脏事件(AD −2.97% [95% CI, −5.14% to −0.79%])(HR=0.48 [95% CI, 0.28 to 0.83], P = .007)。不过IVUS组因靶病变血管再建导致的缺血发生更少(17 [2.5%] vs 33 [5.0%] ,HR=0.51 [95% CI, 0.28 to 0.91], P = 0.02)。心脏死亡和靶病变相关心肌梗死在IVUS组和血管造影组差异不大:心脏死亡 3(0.4%) vs 5 (0.7%),HR, 0.60 [95% CI, 0.14 to 2.52], P = 0.48;靶病变相关心肌梗死仅见于血管造影组的1名 (0.1%) 患者 (P = 0.32)。

研究结果表明,对长冠状动脉病变植入依维莫司涂层支架时,使用IVUS指导与血管造影相比,可以减少1年内心脏主要不良事件发生率。进一步说,该组的靶病变血管重建风险更小。
