RESUMEN
Based on correlation analysis of stroke, recorded in Khanty-Mansiysk during 5 years, and standard meteorological factors, we found the significant relationship between the frequency of stroke and daily temperature amplitude. The positive correlation between the frequency of stroke and between-day changes in air temperature in the combination with changes in atmospheric pressure during 3 h was identified. A maximal number of strokes was recorded in December, April, May and July and a minimal number was in January, June, August and September. The frequency of stroke and fatal outcomes did not depend on the season.

A study of registry data revealed that morbidity, mortality, early lethality and frequency of secondary cases of stroke were significantly lower compared to those in the Russian Federation that could be explained by the younger mean age of the population in the Khanty-Mansi autonomous okrug (KMAO). Annual frequency of new cases of stroke among men was higher than among women though the prevalence of risk factors was lower in men. The levels of morbidity in men and women differed significantly than in the country as a whole. Changes in the clinical course of stroke were noted over the period of the study that was supported by the data on the significant reduction of the morbidity with the absence of the dynamics in the mortality and early lethality. The structure of stroke forms was similar to that in the Russian Federation but significant differences were found between men and women. The ratio between the number of cases of stroke of the carotid artery territory and that of stroke of the vertebral-basilar system was similar to the ratio recorded in the Russian Federation.

The parameters of blood lipid spectrum have been analyzed in 421 patients who survived cerebral stroke and transitory ischemic attacks in 2004-2008. The study included people of Khanty-Mansiysk and Khanty-Mansi autonomous okrug and watchmen. The statistical analysis did not reveal differences between mean concentrations of total cholesterol, high and low density lipoproteins and triglycerides in the settled population and in watchmen. Mean values of all parameters, with the exception of high-density lipoprotein, were higher compared to normative values. The highest frequency of deviations was found for low-density lipoproteins (63.5% of cases). The highest concentrations of total cholesterol and low-density proteins were seen in patients after transitory ischemic attacks regardless of their sex. The comparison of blood lipid spectrum parameters in different age groups revealed significant differences only for total cholesterol.

Based on register data, epidemiologic indicators of cerebral stroke for the population of Khanty-Mansiysk autonomic okrug and values of early mortality and mean ages of patients have been obtained. The structure of acute disturbances of brain blood circulation has been studied. It has been shown that morbidity and mortality from cerebral stroke in the population of autonomic okrug is significantly lower compared to the same indicators in the Russian Federation in whole. Morbidity among men is higher than among women. An analysis of stroke risk factors revealed that the prevalence of some factors is significantly higher in the population of the okrug compared to other the Russian regions.
