摘要 目的探讨经皮冠状动脉介入治疗(PCI)术后,氯吡格雷单用及联用阿司匹林对血小板活血的影响。方法双抗组30例PCI术后患者,予氯吡格雷和拜阿司匹林双联抗血小板聚集治疗。单抗组20例PCI术后患者,予单用氯吡格雷抗血小板聚集治疗。两组患者均于术前30min,术后2h、24h、48h、72h、1周、2周分别进行血小板活化指标水平(CD14+CD42a+)的检测。结果两组PCI术后的的血小板活化指标均明显高于术前,说明经皮冠状动脉介入治疗能激活血小板的作用;且两组术后各阶段血液测试,发现血小板活化指标呈抛物线形态,即于72h以前呈上升趋势,于72h以后逐渐趋于稳定,72h达到峰值,术后1周时双抗组测量指标已经基本恢复术前状态,而单抗组2周测量指标仍未恢复术前状态。术前、术后2h、24h,两组活化血小板水平变化比较无明显统计学差异(P>0.05),术后48h、72h、1周、2周,两组活化血小板水平指标变化比较均有显著统计学差异(P<0.01)。结论冠心病急性冠状动脉综合征的发生与发展过程中,血小板活化指标变化起到非常重要的作用,利用经皮冠状动脉介入治疗方法,能够明显激活血小板活性因子,易造成血栓形成与血管的再堵塞,本研究表明PCI术后,氯吡格雷联用拜阿司匹林是控制血小板活性的有效方法,且较单用氯吡格雷具有更好的疗效。
