摘  要:目的:比较不同剂量氯吡格雷对冠心病介入治疗患者血小板功能状态及血液流变学的影响.方法:选择2010年10月~2013年12月于本院进行介入治疗的70例冠心病患者为研究对象,均采用氯吡格雷治疗,随机分为常规剂量组(35例)和大剂量组(35例,负荷量600mg,维持量150mg/d),比较两组介入治疗后6h、12h及24h的血小板功能状态及血液流变学指标状况.结果:与常规剂量组比较,大剂量组介入治疗后6h、12h及24h的血液流变学指标[6h:全血低切黏度(11.13±1.53) mPa·s比(8.89±1.33) mPa·s,血浆黏度(1.75±0.16) mPa·s比(1.41±0.14) mPa·s,全血还原低切黏度(24.83±2.18) mPa·s比(21.87±1.99) mPa·s],血小板活化指标-糖蛋白Ⅱb/Ⅲa[6h:(15.98±1.53)%比(13.85±1.38)%],血小板其他功能指标:P选择素[6h:(17.38±1.33) μg/L比(14.76±1.23) μg/L]、血小板聚集率[6h:(41.57±4.68)%比(35.24±3.76)%]均明显降低(P均<0.05).结论:大剂量氯吡格雷对冠心病介入治疗患者血流变及血小板功能状态的影响更大.Objective: To compare the influence of different doses of clopidogrel on platelet function state and hemo- theological indexes in patients With coronary heart disease (CHD) undergoing PCI. Methods: A total of 70 CHD patients, who received PCI in our hospital from Oct 2010 to Dec 2013, were enrolled as subjects. All patients received clopidogrel treatment, and were randomly divided into routine dose group (n = 35) and large dose group (n = 35, loading dose 600rag, maintenance dose 150mg/d). Platelet function and hemorheologieal indexes on 6h, 12h and 24h after PCI were compared between two groups. Results: Compared with routine dose group, there were signifi- cant reductions in hemorheological indexes on 6h, 12h and 24h after PCI [6h: whole blood viscosity at low shear rate..

Conclusion: Large dose of clopidogrel possesses more significant influence on hemorheological and platelet function indexes in CHD patients undergoing PCI.
