摘要 目的:探讨血栓弹力图(TEG)与血小板参数之间的相关性及其在急性冠状动脉综合征(ACS)抗血小板治疗中的应用价值。方法:连续选择91例接受经皮冠状动脉介入治疗(PCI)的ACS患者,于PCI术后次日晨采集静脉血进行TEG检测,并同步测定血常规。结果:①血栓最大弹力度(MA)、血小板计数(PLTs)、血小板压积(PCT)分别在ACS不稳定性心绞痛(UA)组、急性非ST段抬高型心肌梗死(NSTEMI)组和急性ST段抬高型心肌梗死(STEMI)组间差异有统计学意义(均P<0.05);②ACS患者血小板参数中PLTs与TEG参数中血凝块形成时间(K)呈负相关(r=-0.251,P<0.05),与血凝块形成速度(Angle)、MA、凝血指数(CI)呈正相关(r=0.308,0.525,0.388;均P<0.01);PCT与K呈负相关(r=-0.239,P<0.05),与Angle、MA、CI呈正相关(r=0.327,0.477,0.390;均P<0.01);③PLTs与MA高度相关,但异常的PLTs对应的MA值范围较广泛。结论:ACS患者TEG与血小板参数之间存在相关性,二者联合监测对PCI术后抗血小板治疗具有一定的指导作用。 Objective:To evaluate the correlation between the thromboelastogram(TEG)and conventional platelet parameters and its effectiveness in determining the coagulation status in patients with acute coronary syndrome(ACS)undergoing percutaneous coronary intervention(PCI).Method:A total of 91 patients with ACS were enrolled.R time,alpha angle,K time,maximal amplitude(MA)and coagulation index(CI)were measured by TEG while routine platelet parameters were tested simultaneously after PCI.Result:There were statistical differences in MA,platelet count(PLTs)and plateletcrit(PCT)among the three groups of ACS patients(all P〈0.05).The PLTs was negatively correlated with K time(r=-0.251,P〈0.05)and positively associated with alpha angle,MA and CI(r=0.308,0.525,0.388;P〈0.01)respectively.The PCT was negatively correlated with K time(r=-0.239,P〈0.05)and positively associated with alpha angle,MA and CI(r= 0.327,0.477,0.390;P〈0.01)respectively.Some MA values corresponding with platelet count beyond normal references remain in the normal range.Conclusion:There is relationship between TEG-based indicators and platelet parameters in ACS patients undergoing PCI.The combination of the two methods may help to monitor the coagulation status to ensure the security of antithrombotic therapy.
