摘要
目的:探讨高维持剂量(150 mg/d)氯吡格雷是否能抑制动脉粥样硬化炎症反应。方法:经Grace评分分级的高危急性冠状动脉综合征(ACS)患者80例,经皮冠状动脉腔内介入术(PCI)后随机分为氯吡格雷75 mg/d组(n=40)与氯吡格雷150 mg/d组(n=40),30 d后均以75 mg/d维持治疗。分别检测PCI术前、30 d的高敏C反应蛋白(hs-CRP)、白介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)水平。随访术后6个月的主要不良心脏事件(MACE)及出血事件的发生情况。结果:1.氯吡格雷150 mg/d组和75 mg/d组,术前hs-CRP、IL-6、TNF-α水平比较差异无统计学意义(P>0.05);2.2组PCI术后30 d血清hs-CRP、IL-6、TNF-α水平均较术前显著降低(P<0.01),且氯吡格雷150 mg/d组较75 mg/d组对上述炎症因子的抑制程度更明显(P<0.05);3.2组MACE发生情况差异有统计学意义(P<0.05),而出血事件发生率差异无统计学意义(P>0.05)。结论:PCI围术期应用高维持剂量氯吡格雷,可以进一步抑制高危ACS患者动脉炎症反应而不增加出血风险,有助于降低短期MACE发生率。
Objective:To investigate the effect of high maintenance doses of clopidogrel(150 mg/d) on the markers of inflammation(hs-CRP,IL-6、TNF-α) in high-risk patients with acute coronary symptom(ACS) undergoing percutaneous coronary intervention(PCI).Methods:A total of 80 high-risk(through the GRACE’ classification process) ACS patients undergoing drug-eluting stent implantation were randomly divided to the colpidogrel 75 mg/d group(n=40) and the colpidogrel 150 mg/d group(n=40),treated as for 30 days after PCI.After 30 days all patients received clopidogrel 75 mg/d for long-term maintenance treatment.The peripheral venous blood was collected to determine hs-CRP,IL-6 and TNF-α for all patients before PCI and 30 days after PCI.The results thus obtained were analyzed and compared accordingly.Via 6 months follow-up,the incidence of MACE and bleeding events in two groups were recorded.Results:1.hs-CRP,IL-6,TNF-α in the colpidogrel 150 mg/d group and 75 mg/d group were not significantly significant difference before PCI(P〉0.05);2.hs-CRP,IL-6,TNF-α were significantly decreased in the two groups one month after PCI(P〈0.01),hs-CRP,IL-6,TNF-α were significantly restrained in the colpidogrel 150 mg/d group than the colpidogrel 75 mg/d group(P〈0.05);3.The incidence of MACE was significantly different between the two groups(P〈0.05),there were not significant difference in the incidence of hemorrhage between the two groups(P〉0.05).Conclusion:The high maintenance dose of clopidogrel can further reduce the inflammation of arteries and not increase the risk of bleeding.Accordingly,it helps to decrease MACE in short time for high-risk ACS patients.
