【摘要】目的:在冠心病患者中通过血栓弹力图(TEG)测定血小板抑制率(AA、ADP),评价抗血小板药物作用效果。方法:对本院使用阿司匹林和氯吡格雷双联抗血小板治疗的707例冠心病住院患者进行TEG测试,测得二磷酸腺苷(ADP)受体途径诱导的血小板抑制率和花生四烯酸(AA)途径诱导的血小板抑制率,根据ADP和AA抑制率参考值的不同,将其划分为低抑制率、正常抑制率和高抑制率3组,并分别对各组的普通杯R、K、角度、MA值的相关性进行统计学分析。结果:按ADP抑制率分组的3组间的R、K、角度差异不显著;MA值低抑制率组与其他两组间比较差异显著,但正常组与高抑制率组间差异不显著;三组间AA抑制率差异显著;按AA抑制率分组的3组间的R、K、角度、MA值差异不显著;ADP抑制率三组间差异显著。结论:血栓弹力图普通杯无法准确评估阿司匹林和氯吡格雷抗血小板的疗效,但AA抑制率与ADP抑制率之间呈一定的正相关,应根据AA抑制率和ADP抑制率的差异评估阿司匹林和氯吡格雷的药物疗效,调整临床用药方案。

【Abstract】Objective To determine platelet inhibition rate(AA, ADP) of patients with coronary heart disease(CHD) by thrombelastography(TEG) in order to evaluate the effect of antiplatelet drugs.Methods The thrombocytopenia induced by adenosine diphosphate(ADP) receptor pathway and arachidonic acid(AA) pathway were measured in 707 patients hospitalized with coronary heart disease treated with aspirin and clopidogrel antiplatelet therapy. The correlation between the values of common cup R, K, angle and MA was analyzed.Results The difference of R, K and angle between the three groups was not statistically significant, but the inhibition rate, low inhibition rate and high inhibition rate. AA inhibition was statistically different values of MA were statistically different between the groups with low inhibition rate and normal between the two groups. Compared with the common cup results of AA inhibition group, there was no significant difference in R, K, angle and MA values between the three groups.Conclusion The therapeutic effect of aspirin and clopidogrel on platelet cannot be evaluated accurately, but there is a positive correlation between AA inhibition rate and ADP inhibition rate. The therapeutic effect of aspirin and clopidogrel should be evaluated according to the difference of AA inhibition rate and ADP inhibition rate.

血栓弹力图(TEG)是一种床旁检测手段,可准确地进行血小板功能检测;本研究利用TEG测定冠心病患者血小板抑制率(AA、ADP),旨在评价抗血小板药物作用效果。

1.资料与方法

1.1 一般资料

以我院2015年1月—2017年7月住院治疗的707例冠心病患者为研究对象,女196例,男511例;平均年龄66.0±9.8岁。联合服用氯吡格雷(75mg/d)阿司匹林(100mg/d)。

1.2 分组

所有患者抽静脉血测花生四烯酸(AA,参考值:50%~95%)通路途径和二膦酸腺苷(ADP,参考值:30%~90%)受体途径诱导的血小板抑制率,按照参考值分别分为AA和ADP低、正常、高抑制率3组,并且对各组的普通杯R、K、角度、MA值(TEG方法检测)进行分析。

1.3 统计学处理

应用SPSS19.0软件进行分析,采用方差分析、相关和回归分析,P<0.05为差异具有统计学意义。

2.结果

2.1 分组

患者分组情况见表1。

2.3 ADP抑制率和AA抑制率相关性和回归分析线性相关分析

ADP抑制率和AA抑制率相关性和回归分析线性相关分析显示PEARSON相关系数r=0.361,P<0.01,有统计学意义。回归方程为ADP=37.183+0.327AA,P<0.01,回归方程成立,AA与ADP之间存在线性关系。

3.讨论

冠心病患者PCI术后需口服阿司匹林、氯吡格雷等抗血小板药物,其中阿司匹林可抑制花生四烯酸转化,达到抑制血小板的激活和聚集作用。氯吡格雷是通过选择性、不可逆地与血小板表面的二磷酸腺苷(ADP)受体结合,从而阻滞ADP依赖性的血小板GPIIB/IIIa活化,减少血小板的激活和聚集[1,2]。

TEG可根据公式计算出AA、ADP诱导血小板抑制率,指导临床抗血小板及抗凝药物应用,特别是可在ACS患者强化抗血小板治疗方面发挥重要作用。

在本研究中,冠心病患者阿司匹林低抑制率为30.1%,氯吡格雷低抑制率为21%。这部分患者可能存在阿司匹林和氯吡格雷抵抗,因此对阿司匹林和氯吡格雷的作用反应低下。

本研究结果提示,TEG普通杯无法准确评估阿司匹林和氯吡格雷抗血小板的疗效,但AA抑制率与ADP抑制率的差异对评价阿司匹林和氯吡格雷的疗效具有一定意义。
