For the purpose of studying the epidemiology and risk factors of stroke on the basis of standardized international research WHO MONICA program criteria the incidence, death rate and case fatality of stroke are analyses, as well as the prevalence of arterial hypertension in various regions of Siberia.

Obtained results testifies that the prevalence of an arterial hypertension in Novosibirsk according to 140/90 criteria for persons 24-64 years - 48 %. In subpolar regions of the Asian North the prevalence of an arterial hypertension among the native population is much smaller, than that for European population living in the same regions. However at the native Asian population of southern regions of Siberia (Buryats, Tuvinian, Altaians) the prevalence of an arterial hypertension is much higher, than in northern natives. The prevalence of fatal and not fatal cases of stroke in Novosibirsk takes the most unfavourable place in the age of 35-64 years among the other MONICA centers. High frequency of it is connected first of all with the high prevalence of an arterial hypertension, late its detectability and the unsatisfactory control of blood pressure.

The stroke register in other Siberian centers testifies the tendency to growth of the incidence and death rate from stroke. The results of the population-based epidemiological stroke study at native and indigenous population of Yamal-Nenets autonomous region (9634 inhabitants) for the period 1996 up to 2003 have revealed rather high levels of incidence and death rate from stroke (203,7 and 111,6 on 100000 population in one year, accordingly), that are along with the previously made conclusion about an existing gradient of parameters between regions of Siberia: increase in parameters in the direction of east and northern territories. The age and sex standardized case fatality in acute period of a stroke in Yamal-Nenets autonomous region (41,3%) are similar to the standardized case fatality in Anadyr (40,7%) in 1987-88. The same parameters are 1,1-1,5 times more than that in Krasnoyarsk (37,5%), Novosibirsk (31,7%) and Tynda (27,5%) that means the severe course of a stroke in regions of Far North or insufficiently effective treatment in the acute period of stroke.
