目的 探讨血栓弹力图对脑梗死患者抗血小板治疗的指导价值及阿司匹林抑制率对脑微出血的影响.方法 回顾性分析2019年4月至2021年7月于阳江市人民医院治疗的88例脑梗死患者的临床资料.所有患者均接受阿司匹林抗血小板治疗,7d后,利用血栓弹力图对血小板抑制率及有关参数进行检测,按照检测结果将阿司匹林反应低下的患者设置为A组(23例),无阿司匹林反应低下的患者设置为B组(65例).改用氯吡格雷对A组患者持续抗血小板治疗7 d后,再次检测血小板抑制率.然后依据阿司匹林血小板抑制率分为良好组(血小板抑制率超过75％)、一般组(血小板抑制率为50％～75％)及无效组(血小板抑制率不足50％),分析阿司匹林抑制率对脑微出血的影响.结果 88例患者经阿司匹林干预后,42例(47.73％)恢复良好,23例(26.14％)恢复一般,23例(26.14％)反应低下,有效率为73.86％(65/88).23例阿司匹林反应低下者改服氯吡格雷后,19例(82.61％)恢复良好,3例(13.04％)恢复一般,1例(4.35％)反应低下,有效率为95.65％(22/23).A组治疗7 d后花生四烯酸(AA)诱导途径、腺苷二磷酸(ADP)诱导途径高于治疗前(P<0.05).B组治疗7 d后α角小于治疗前,最大振幅(MA)低于治疗前,反应时间(R)、凝固时间(K)值大于治疗前(P<0.05).无效组脑微出血发生率低于良好组,脑卒中发生率、MA-AA值高于一般组和良好组,R、K值低于一般组和良好组(P<0.05);一般组脑微出血发生率、R值、K值低于良好组,MA-AA值高于良好组(P<0.05).结论 血栓弹力图对脑梗死患者的抗血小板治疗具有一定指导价值,有利于个体化治疗,值得推广应用.阿司匹林抑制率维持于50％～75％有助于减少脑微出血的发生.
