【摘要】 目的：研究经典双抗治疗对急性脑梗死患者脑血管储备功能的影响，并进行经颅多普勒超声(TCD)评价。方法：参考随机对照双盲的试验原则，将74例急性脑梗死患者分为对照组与研究组，对照组采取阿司匹林治疗，研究组采取双抗(阿司匹林联合氯吡格雷)治疗。利用TCD评价患者的脑血管储备功能。结果：研究组治疗总有效率高于对照组，组间对比差异有统计学意义(P<0.05);治疗后，大脑中动脉平均血流速度(MFV)、屏气指数(BHI)、脑血管储备功能(CVR)上升，研究组上升情况优于对照组，组间对比差异有统计学意义(P<0.05);搏动指数(PI)下降，研究组下降情况优于对照组，组间对比差异有统计学意义(P<0.05)。结论：经典双抗治疗可加强急性脑梗死的治疗效果，提高患者脑血管储备能力。

    [Abstract] Objective： To study the effect of classical dual-antibody therapy on cerebrovascular reserve function in patients with acute cerebral infarction and to evaluate it by transcranial doppler ultrasound (TCD). Method： A total of 74 patients with acute cerebral infarction were divided into the control group and the study group according to the randomized control double-blind experiment principle. TCD was used to evaluate the cerebrovascular reserve function of patients. Result： The total effective rate of the study group was higher than that of the control group ......
