目的 探讨负荷剂量瑞舒伐他汀对不稳定型心绞痛(UAP)患者经皮冠状动脉介入治疗(PCI)术后炎症因子的影响.方法 选择我院住院的UAP患者68例,随机分为对照组(术前不予瑞舒伐他汀,术后给予10 mg/d,n=34)和强化瑞舒伐他汀组(术前2 d给予20 mg/d,术后给予10 mg/d,n=34).分别于PCI术前、术后18~24 h检测心肌损伤标志物cTnI、CK-MB以及超敏C反应蛋白(hs-CRP)、肿瘤坏死因子-α(TNF-α)、血清干扰素-γ(IFN-γ)等炎症因子的表达.结果 ①PCI术后18~24 h,强化瑞舒伐他汀组患者cTnI高于正常高值的发生率低于对照组(P〈0.05).术后CK-MB两组比较差异无统计学意义(P〉0.05).②PCI术后18~24 h,hs-CRP、TNF-α、IFN-γ均较术前进一步升高,对照组较强化瑞舒伐他汀组升高明显,两组各项指标比较差异有统计学意义(P〈0.05).结论 PCI术前给予20 mg瑞舒伐他汀可以有效地降低炎症因子hs-CRP水平及术后心肌损伤的发生率.
Objective To investigate the effects of loading - dose rosuvastatin on inflammatory cytokines from unstable angina patients after percutaneous coronary intervention (PCI). Methods A total of 68 unstable angina patients were enrolled. Unstable angina patients were randomized to control group ( n = 34) or pretreatment with loading - dose rosuvastatin group (20 rag/d, n = 34). cTnI, CK - MB, hs- CRP, TNF-αand IFN -γ were measured respectively before PCI and 18 -24 h post PCI. Results (1)Compared with control group, rosuvastatin effectively reduced cTnI elevating after PCI (P 〈 0.05). The CK- MB level was not statistically different between the two groups after PCI( P 〉0.05 ). @)The serum levels of hs - CRP, TNF -α and IFN -γ were all increased in both groups after PCI. However, levels of hs - CRP, TNF --α and IFN -γ in control group were higher than those in rosuvastatin group after PCI ( P 〈 0. 05 ). Conclusion Loading - dose rosuvastatin ( 20 mg ) pretreatment can reduce post- PCI myocardial inflammation and periprocedural myocardial injury effectively.
