我们分析了42例63-86岁的健康流动受试者的血液学因素与大脑中动脉血流速度的关系。我们发现平均流速与红细胞压积（r = -0.37, p < 0.02）和纤维蛋白原浓度（r = -0.42, p < 0.005）呈显著负相关。这两个变量与速度独立相关，共同解释了平均速度方差的29%。在解释经颅多普勒结果时，应考虑红细胞压积和纤维蛋白原浓度。
We analyzed the association between hematologic factors and blood velocity of the middle cerebral artery in 42 healthy ambulatory subjects aged 63-86 years. We found a significant inverse association between mean velocity and both hematocrit (r = -0.37, p < 0.02) and fibrinogen concentration (r = -0.42, p < 0.005). These two variables are independently associated with velocity and together explain 29% of the variance in mean velocity. Both hematocrit and fibrinogen concentration should be considered in the interpretation of transcranial Doppler findings in this population.
