Objective To evaluate the effect of rosuvastatin on the functions of the surviving myocardium and arteriosclerosis plaque in patients with ST-segment elevation after acute myocardial infarction (STEMI) and percutaneous coronary intervention (PCI). Methods Sixty-five STEMI patients were randomized to receive 40 mg simvastatin (n=32) or 10 mg rosuvastatin (n=33) before sleep in addition to conventional medications. Before PCI and after the 12-month medications, the plasma levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) were measured, and echocardiography and 99TCm-MIBI single-photon emission computed tomography (SPECT) were performed to assess the therapeutic effects. Results At the end of 12 months, the patients in simvastatin group showed significantly reduced total cholesterol, LDL-C, CRP, TNF-a, and 99TCm-MIBI uptake fraction. In rosuvastatin group, these reductions were even more obvious; the intima media thickness (IMT) of the common carotid artery was reduced significantly after a 12-month rosuvastatin therapy, but almost remained unchanged after simvastatin therapy. Conclusion Rosuvastatin therapy in addition to conventional medications can significantly reduce IMT and improve the functions of the surviving myocardium in patients with STEMI after PCI.%目的 探讨瑞舒伐他汀作为新型他汀类药物对急性ST段抬高型心肌梗死(STEMI)患者经皮冠状动脉介入治疗(PCI)后存活心肌功能及动脉粥样硬化的影响.方法 用随机方法将65例急性ST段抬高型心肌梗死(STEMI)患者分为常规药物加辛伐他汀(黙沙东制药有限公司,40 mg,睡前)组(n=32)和常规药物加瑞舒伐他汀(阿斯利康制药有限公司,10 mg,睡前)组(n=33),随访12个月,测定患者在介入治疗前和治疗后12个月的血脂及血浆C-反应蛋白、肿瘤坏死因子-α(TNF-α)水平,并观察颈动脉内膜中层厚度(IMT)及99Tcm-MIBI摄取分数的改变.结果 辛伐他汀组及瑞舒伐他汀组患者治疗12个月后,总胆固醇、LDL胆固醇、C-反应蛋白及肿瘤坏死因子-α均有显著下降,而99Tcm-MIBI摄取分数均显著增加；且瑞舒伐他汀组治疗后总胆固醇、LDL胆固醇、C-反应蛋白、肿瘤坏死因子-α下降幅度及9Tcm-MIBI摄取分数增加幅度较辛伐他汀组大.瑞舒伐他汀组患者用瑞舒伐他汀治疗12个月后,颈动脉内膜中层厚度(IMT)显著下降(P＜0.01),而辛伐他汀组治疗12个月后,颈动脉内膜中层厚度(IMT)无明显的变化.结论 在PCI术及应用常规药物基础上加用瑞舒伐他汀可使急性ST段抬高型心肌梗死患者颈动脉内膜中层厚度明显下降并进一步改善存活心肌细胞功能.
