Abstract: It is well known that extraordinarily high levels of erythrocyte concentration in the blood as observed in plethoric patients are a warning signal for cerebral apoplexy.
With radical changes in the social environment, psychogenic stress and cigarette smoking have pushed the incidence of erythrocytosis upward.
In rural areas, where anemia has traditionally been a major health threat, the nutritional conditions have been improved dramatically. Situations are such that more attention should be directed toward plethora.
The rise in Ht reading means the rise in blood viscosity, which could trigger off cerebral infarction in elderly people suffering from arteriosclerois.
People whose Ht reading is constantly high have a very high risk of cerebral apoplexy. Our survey of the people aged 70 and above found that the incidence of cerebral apoplexy was 50% in the Ht. 49-51% group and 100% in the Ht. 52% and above. The aged are easily affected by hemoconcentration due to dehydration. So, the slightest rise in Ht levels could lead to cerebral apoplexy. With a view to preventing the disease, the authors propose, the Ht. level of the old people should be kept below 43%.
