目的 探讨阿托伐他汀联用依折麦布预处理对PCI围术期高敏C反应蛋白(hs-CRP)的影响.方法 连续入选具有典型稳定性心绞痛症状的患者156例,标准治疗基础上随机分为他汀组78例(阿托伐他汀20 mg/晚)与联合组78例(阿托伐他汀10mg/晚+依折麦布10mg/晚),治疗7d后行PCI,分别于PCI术前、术后8、24、48 h和7d检测hs-CRP.结果 与PCI术前比较,术后7d2组TC、LDL-C均明显降低(P＜0.01),且联合组术后较他汀组降低更明显(P＜0.05);与PCI术前比较,联合组和他汀组术后8 h hs-CRP明显升高,术后24 h hs-CRP达高峰(P＜0.01),48 h hs-CRP处于升高水平(P＜0.01),术后7 d hs-CRP无明显变化(P＞0.05);联合组术后8、24[(6.10±2.27)mg/L vs (7.08±3.78)mg/L]和48 h hs-CRP水平明显低于同时间他汀组(P＜0.05),术后7d2组hs-CRP比较无显著差异[(2.02±1.35)mg/L vs (2.15±1.23)mg/L,P＞0.05].结论 阿托伐他汀联用依折麦布较阿托伐他汀单用对围术期急性炎性反应具有更明显的改善作用.%Objective To study the effect of combined atorvastatin and ezetimibe pretreatment on perioperative hs-CRP after elective PCI.Methods One hundred and fifty-six patients with typical chronic stable angina pectoris were randomly divided into atorvastatin treatment group (n=78) and combined atorvastatin and ezetimibe treatment group (n=78).Their serum hs-CRP,TC and LDL-C level was measured before PCI,at hours 8,24,48 and on day 7 after PCI.Results In comparision with pre-operation,the serum TC and LDL-C levels were significantly lower in two groups (P＜0.01) and in combined atorvastatin and ezetimibe treatment group than in atorvastatin treatment group on day 7 after PCI (P＜0.05).The serum hs-CRP level was significantly higher in two groups at 8 h after PCI than before PCI,reached its peak at 24 h after PCI,continued to increase at 48 h after PCI (P＜0.01),no significant difference was found between the two groups on day 7 after PCI (P＞0.05).The average serum hs-CRP level was lower in combined atorvastatin and ezetimibe treatment group than in atorvastatin treatment group at hours 8,24 and 48 after PCI (P＜0.05) with no significant change found between the two groups on day 7 after PCI (P＞0.05).Conclusion The effect of combined atorvastatin and ezetimibe pretreatment is better than that of atorvastatin alone on perioperative acute inflammatory reactions after PCI.
