本文探讨了300例高血压病,50例高血压性脑出血和18例脑梗塞患者的动脉均压与全血粘度的相关性。比较了这三组的回归方程特性、动脉均压、全血粘度和压力粘度比值的区别。结果发现:各组直线回归斜率无显著差异;脑出血组动脉均压最高,脑梗塞组最低;脑出血组与脑梗塞组的全血粘度无明显差异(p>0.05);压力粘度比值以脑梗塞组最低,与脑出血和高血压病组比较均有非常显著差异(p<0.01)。文章以Poiseuille定律讨论了动脉均压、全血粘度的相关性和在急性脑血管病发病中的意义,认为慢性高血压的治疗,应在降低血压的同时注意降低全血粘度并维持正常的压力粘度比值,才能有效地预防中风的发生。
This article explored the correlation between arterial pressure and whole blood viscosity in 300 hypertensive patients, 50 hypertensive cerebral hemorrhages and 18 cerebral infarctions. The differences of the regression equations, arterial pressure, whole blood viscosity and pressure-viscosity ratio of these three groups were compared. The results showed that there was no significant difference in the linear regression slope between groups; the mean arterial pressure was the highest in cerebral hemorrhage group and the lowest in cerebral infarction group; the whole blood viscosity in cerebral hemorrhage group and cerebral infarction group had no significant difference (p> 0.05) The infarction group was the lowest, with a significant difference compared with the cerebral hemorrhage and hypertension group (p <0.01). The article discusses the relationship between arterial pressure, whole blood viscosity and the incidence of acute cerebrovascular disease based on Poiseuille’s law. It is believed that the treatment of chronic hypertension should reduce the blood pressure while reducing the viscosity of whole blood and maintaining the normal pressure Viscosity ratio, in order to effectively prevent the occurrence of stroke.
