目的 比较冠状动脉狭窄50%～70%的冠心病人群中,40 mg阿托伐他汀与10 mg阿托伐他汀和10 mg依折麦布联合治疗的调脂作用和安伞性.探讨单用他汀治疗和联合治疗对基质金属蛋白酶(MMP)的影响.方法 选取冠状动脉狭窄50%～70%的冠心病患者42例(不置入支架),分为较大剂量阿托伐他汀(40 mg)组(单用他汀组)19例和小剂量阿托伐他汀(10 mg)联合依折麦布(10 mg)组(联合治疗组)23例.在服药前,用药4周,用药12周分别测定总胆同醇(1℃),甘油三酯,低密度脂蛋白胆固醇(LDL-C),高密度脂蛋白胆固醇,肝功能,肾功能,肌酸激酶,基质金属蛋白酶_2(MMP-2),基质金属蛋白酶-9(MMP-9),基质金属蛋白酶组织抑制因子-1(TIMP-1).结果 (1)单用他汀组和联合治疗组均在4周就可以明显降低患者的TC,LDL-C.12周时单用他汀组的LDL-C是(1.94±0.49)mmol/L,较前下降37.82%,联合治疗组的LDL-C是(1.92±0.54)mmol/L,较前下降38.26%,两组之间差异无统计学意义.(2)单用他汀组和联合治疗组的患者肝功能,肾功能,肌酸激酶在用药后无明显升高.(3)单用他汀组的MMP-2,MMP-9在12周时均较基线有明显降低,TiMP-1有明显升高.结论 (1)单用他汀治疗和联合治疗降脂疗效无差异.(2)两种治疗都没有引起患者肝、肾功能异常和肌酶异常.(3)40 mg阿托伐他汀治疗明显降低患者MMP-2、MMP-9,升高TIMP-1.
