摘要 目的观察经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后无复流患者经尼可地尔治疗后其冠状动脉血流改善情况,探讨尼可地尔对无复流患者心肌微灌注及其远期预后的影响。方法将263例PCI术后无复流患者随机分为治疗组135例和对照组128例。2组基础治疗相同,治疗组术中静脉泵入尼克地尔48h后口服3个月,对照组只进行基础治疗而不给予尼克地尔。比较2组术前、术后90d炎性和氧化应激指标高敏C反应蛋白(hypersensitive C reactive protein,hs-CRP)、超氧化物歧化酶(superoxide dismutase,SOD)、丙二醛(malondialdehyde,MDA)变化以及心功能指标,于术前及术后90d采用静息99mTc-MIBI心肌灌注显像17节段积分法评价2组术后心肌灌注缺损积分,随访24个月记录主要心血管不良事件(major adverse cardiovascular events,MACE)。结果术后90d2组hs-CRP、MDA均较术前明显降低,心肌灌注缺损积分均较术后7d明显降低,SOD水平均较术前明显升高,差异有统计学意义(P<0.05);术后90d治疗组hs-CRP、MDA、心肌灌注缺损积分均明显低于对照组,SOD高于对照组,差异有统计学意义(P<0.05)。术后90d2组左心室射血分数(left ventricular ejection fraction,LVEF)和左心室收缩末容积指数(left ventricular endsystolic volume index,LVESVI)均较术前明显升高,室壁运动积分指数(wall motion score index,WMSI)均较术前明显下降,差异有统计学意义(P<0.05);术后90d治疗组LVEF水平明显高于对照组,WMSI低于对照组,差异有统计学意义(P<0.05),而2组术后LVESVI差异无统计学意义(P>0.05)。随访24个月,治疗组MACE发生率明显低于对照组,差异有统计学意义(P<0.05)。结论无复流患者尽早给予尼可地尔静脉泵入后继续维持口服治疗3个月,可降低炎症反应,减少氧化应激,增加心肌微灌注,提高心功能,进而改善患者长期预后。
