阿托伐他汀对急性冠脉综合征患者血清MMP22及TIMP22的作用.doc

阿托伐他汀对急性冠脉综合征患者血清MMP-9 MMP-2 及hs-CRP 的影响 摘要: 目的: 研究应用阿托伐他汀(atuovastatin) 对急性冠脉综合征(acute coronary syndromes ACS) 患者血清MMP-9 MMP-2 hs-CRP 的影响。方法: 选定ACS 患者61 例,稳定型心绞痛(SA) 患者19 例及正常对照组30 例。随机将ACS 患者分为阿托伐他汀组(33 例) 和常规组(28 例) ,比较各组间血清MMP-9 MMP-2 及hs-CRP的水平变化。结果: ACS 组与SA 组及正常对照组之间血清MMP-9 MMP-2 及hs-CRP水平相比差异有统计学意义,两组干预后血清MMP-9 MMP-2、及hs-CRP水平相比差异有统计学意义。结论: 阿托伐他汀可降低ACS 患者血清MMP-9 MMP-2及 hs-CRP 水平, 减少冠状动脉粥样斑块基质成分的降解和炎症反应,从而起到稳定动脉粥样硬化斑块的作用。关键词: 急性冠脉综合症; 基质金属蛋白酶2 ; 基质金属蛋白酶9 ; 高敏C反应蛋白︰阿托伐他汀 The effect of atuovastatin on serum level of matrix metallopro teinase-9 matrix metallopro teinase-2 and High sensitivity C-reactive protein patients with acute coronary syndrome Abstract : Objective : To investigate the influences of atuovastatin on serumMMP-9 MMP2 , and hs-CRP levels of patients with acute coronary syndrome (ACS) . Methods : There were 61 patients with ACS and 19 patients with SA. Meanwhile , 30 cases of age matched control individuals wereselected. Then 61 patients with ACS were randomly divided into two groups : atuovastatin treatmentgroup and regular treatment group. The serum level of MMP-9 MMP?2 and hs-CRP were compared among all groups. Results : There was significant difference in serum level of MMP-9 MMP?2 and hs-CRP between ACS group and SA group and control group. There was significant difference in serum level of MMP-9 MMP?2 and hs-CRP between atuovastatin treatment group and regular treatment group after treatment . Conclusion : atuovastatin could decrease the breakdown of matrix collagen and reduce inflammatory reaction , and it might have a beneficial effect on steadying the plaque.
