Epidemiology of cerebral stroke in the Chuvash Republic

THE AIM OF THE STUDY: to study the epidemiological indicators of cerebral strokes in the Chuvash Republic against the backdrop of the spread of a new coronavirus infection. A cross-sectional epidemiological analytical study was carried out. In our study we included of 11,898 patients aged 18 to 87 years 5,592 (47 %) male and 5,592 (53 %) female. The mean age of stroke development was 64.9 years for men and 70.7 years for women. The maximum increase in the number of cerebral strokes occurred in 2020 and reached to 3,466 patients in absolute terms, or 286.9 per 100,000 population, which is 6.8 % more than in 2018. The increase in the incidence of intracerebral and other intracranial hemorrhages (I61), (I62) in 2020 compared to 2018 was 22.8 %, and in 2021 it significantly decreased by 7.6 % compared to the previous year. Mortality in 2020 in this group of patients (I61), (I62) increased by 9.2 % compared to 2018. The increase in cerebral infarction rates (I63) in 2020 compared to 2018 was 4.99 %, and in 2021 it increased by another 2.9 %. Mortality in 2020 in this group of patients (I63) increased significantly by 18 %, and in 2021 the figure decreased by 12.5 %.

CONCLUSION:  the conducted study demonstrated that the incidence of stroke in the study region remained quite high (288.1 per 100 thousand of the population in 2021) comparing with the average incidence in the Russian Federation (190.9 per 100 thousand). Further, targeted research of the global spread of the disease in the region could be extremely promising for revealing the areas of concern that require targeted improvement.
