| 中文摘要: |
| 目的：在急性冠脉综合征( acute coronary syndromes, ACS )的治疗中，抗血小板治疗及调脂治疗是最基础的治疗方案。近来
有学者提出，氯吡格雷和他汀类药物都经过细胞色素CYP 3A4 途径代谢，二者因存在竞争性抑制，有可能降低氯吡格雷抗血小板
的活性。本试验将针对阿托伐他汀及瑞舒伐他汀进行研究。方法：选择急性冠脉综合症的患者42 例，所有患者均接受氯吡格雷治
疗（负荷剂量300 mg，维持剂量75 mg/d）。随机分配为A、B 两组，A 组（n=20）服用阿托伐他汀治疗（20 mg/d），B 组（n=22 服用瑞
舒伐他汀治疗（10 mg/d）。分别于氯吡格雷服用前、服药治疗后3 天、服药治疗后7 天后采静脉血送检，测定ADP（10 滋mol/L）诱导
的血小板聚集率。结果：阿托伐他汀组（A 组）及瑞舒伐他汀组（B 组）相比，服用氯吡格雷前ADP 诱导的血小板聚集率基线值无
统计学差异。服用氯吡格雷3 日及7 日后，ADP诱导的血小板聚集率明显降低，(3.85± 2.58)vs(3.09± 2.27)，(0.65± 0.88)vs(1.05±
0.95)，P>0.05，无明显统计学差异。结论：氯吡格雷的确可以降低血小板的活性。同时，短期之内氯吡格雷的抗血小板活性未受到
他汀类的影响，包括经过CPY3A4途径的他汀，如阿托伐他汀。 |

| Objective:Antiplatelet treatment is frequently used in high-risk patients with acute coronary syndromes (ACS) who are
also often treated with statins. Some scholars indicated that, clopidogrel and statins were both metabolized through cytochrome CYP
3A4, but clopidogrel antiplatelet activity may be reduced due to the competitive inhibition. The effects of atorvastatin and rosuvastatin
were compared in this study.Methods:42 patients diagnosised as acute coronary syndrome were selected. All patients received treatment
with clopidogrel (loading dose of 300 mg, maintenance dose of 75 mg/d), and were randomly assigned to the groups A, B, Group A
(n=20) was taken atorvastatin treatment (20 mg/d), Group B (n=20) was taken rosuvastatin treatment (10 mg/d). Platelet aggregation
induced by adenosine diphosphate (ADP) at 10 umol/L was measured by impedance method.Results:Compared atorvastatin group
(Group A) with rosuvastatin group (Group B), there are no significant difference in ADP-induced platelet aggregation baseline values
before taken clopidogrel. After clopidogrel therapy for 3 days and 7 days, ADP-induced platelet aggregation was significantly reduced
(3.85 ± 2.58 vs 3.09 ± 2.27, 0.65± 0.88 vs 1.05± 0.95; P>0.05, no statistically significant difference).Conclusion:Clopidogrel can
reduce indeed platelet activity. Meanwhile, the short term antiplatelet activity of clopidogrel is not subject to the influence of statins,
including statin metabolized through CPY3A4 pathway, such as atorvastatin. |
