[目的]比较替格瑞洛与氯吡格雷对早期行经皮冠状动脉支架植入术(PCI)的非ST段抬高型急性冠脉综合征(NSTE-ACS)合并2型糖尿病(T2DM)患者围术期炎症因子的影响.[方法]选择2015年9月至2017年2月本院收治的117例早期行PCI术的NSTE-ACS合并T2DM患者,根据患者服用的抗血小板聚集药物不同将其分为氯吡格雷组(n=72)和替格瑞洛组(n=45).两组均给予常规治疗,均在PCI术前给予阿司匹林片300 mg负荷量,之后为100 mg/d,氯吡格雷组在PCI术前予氯吡格雷300 mg负荷量,之后按每次75 mg,1次/日;替格瑞洛组在PCI术前予替格瑞洛180 mg负荷量,之后按每次90 mg,2次/日.分别于术前、术后6 h、术后24 h、术后3 d、术后1周检测高敏C反应蛋白(hs-CRP)、白介素-6(IL-6)、白介素 1β (IL-1β) 、可溶性 CD40 配体 (sCD40L)水平.[结果]PCI术前,两组hs-CRP、IL-6、 IL-1β 、sCD40L水平比较,差异无统计学意义(P>0.05);PCI后6 h,两组hs-CRP、IL-6、 IL-1β、sCD40L水平较术前升高,差异有统计学意义(P<0.05),两组hs-CRP、IL-6、 IL-1β 、sCD40L升高水平比较,替格瑞洛组低于氯吡格雷组,差异有统计学意义(P<0.05);PCI后24 h、3 d、1周两组hs-CRP、IL-6、 IL-1β 、sCD40L水平均下降,差异有统计学意义(P<0.05),PCI后24 h、3 d、1周两组hs-CRP、IL-6、 IL-1β 、sCD40L下降水平比较,替格瑞洛组低于氯吡格雷组,差异有统计学意义(P0.05);6h post operation ,the levels of hs-CRP, IL-6, IL-1β , and sCD40L were higher than those before operation in both groups(P<0.05).More importantly, the level changes in the ticagrelor group were lower than those in the clopidogrel group(P<0.05).Postoperative 6h,24h,3d, and 7d ,the levels of hs-CRP,IL-6,IL-1β,and sCD40L decreased(P<0.05);the decreases in the ticagrelor group were lower than those in the clopidogrel group(P<0.05).[Conclusion] Both ticagrelor or clopidogrel can effectively inhibit early inflammatory response of diabetic patients complicated with non-ST-elevation acute coronary syndromes after PCI.It is important to note that ticagrelor exhibits better inhibitive effects than clopidogrel.
