阿托伐他汀对高脂血症并颈动脉粥样硬化患者颈动脉内膜中层厚度及炎症标志物的影响

目的 研究阿托伐他汀改善高脂血症并颈动脉粥样硬化患者血清炎症标志物和颈动脉内膜中层厚度的影响.方法 选取高脂血症并颈动脉粥样硬化患者50例,口服阿托伐他汀10mg,Qd,12周,所有患者治疗前及治疗6周、12周后进行血清总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、高敏C反应蛋白(high sen-sitive C-reactive protein,hs-CRP)、血清基质金属蛋白酶一3(Matrix metalloprtease-3,MMP-3)、肿瘤坏死因子(tumor necrosisfactor,TNF-α)检测和颈动脉内膜中层厚度(IMT).结果 与治疗前比较,治疗6周及12周后的TC、TG、LDL-C、hs-CRP、MMP-3、TNF-α均有明显降低(P均<0.05),治疗12周后HDL-C升高(P<0.05)及颈动脉IMT变薄(P<0.05)才有明显统计学意义.结论 阿托伐他汀在有效调脂同时可发挥其抗炎、抗动脉粥样硬化作用,改善血管内皮功能.

Effect of Atorvastatin on Inflammation Markers and Intima-media Thickness of the Common Carotid Artery in Patient with Hyperlipidemic and Atherosclerosis

Objective To investigate the effects of atorvastutin on the levels of plasm imflammation markers (hs - CRP, MMP - 3, TNF - α) and intima - media thickness(ITM) of the common carotid artery in patient with hyperlipidemic and atherosclerosis. Methods Fifty patient with hyperlipidemic and atherosclerosis were treated with atorvastatin (10mg qd) for 12 weeks. The levels of TC, TG, LDL -C, HDL -C, hs -CRP, TNF -α and MMP -3 were detected with radioimmmuneassay and eolorimetric methods. Color Doppler echo-cardiography was used to measure intima -media thickness(ITM) of the common carotid artery after 6 weeks and 12 weeks. Results TC, TG, LDL -C, hs -CRP, TNF -α and MMP -3 were decreased significantly(P < 0.01)after 12 weeks. IMT was decreased signifi-cantly(P < 0.05) and HDL - C was increased significantly (P < 0.05) after 12 weeks. Conclusion Atorvastatin could be effective in re-ducing blood - fat and anti - inflammatory action , regulating blood vessel endothelium (BVE) function and reversing structural chan-ges in IMT of the common carotid artery.
