目的探讨不同性别脑梗塞患者血液流变学改变的差异。方法用血液比粘度计测定和分析１７０例脑梗塞病人及１６７例对照病人血液流变学各项值。结果男性脑梗塞病人全血高切和低切粘度值及红血球压积均比女性高（Ｐ<０．０１，Ｐ<０．００１，Ｐ＜０．００１），而女性的血沉比男性高（Ｐ< ０．００１）。男性脑梗塞病人的全血低切粘度和红血球压积高于男性对照病人（Ｐ<０．０１，Ｐ<０．０５），女性脑梗塞病人的红血球聚集指数高于女性对照病人（Ｐ<０．０１）。结论脑梗塞病人的血液流变学改变存在男女性别差异，血液流变学因素在脑梗塞发病中的影响方式也存在性别差异。
Objective To investigate the difference of hemorheology in patients with different sexes of cerebral infarction. Methods The hemorheology values of 170 cerebral infarction patients and 167 control patients were measured and analyzed by blood viscometer. Results Compared with women, the values of high shear viscosity, low shear viscosity and hematocrit of male patients with cerebral infarction were significantly higher than those of female patients (P <0.001, P <0.001, P <0.001) P <0.001). Low blood viscosity and hematocrit were lower in male patients with cerebral infarction than those in male controls (P <0.01, P <0.05). The index of erythrocyte aggregation in female patients with cerebral infarction was higher than that in female controls (P <0.01) .01). Conclusions The hemorheological changes in patients with cerebral infarction have gender differences. The influencing factors of hemorrheological factors in the incidence of cerebral infarction also have gender differences.
