Abstract
To analyze the main changes in the prevalence of stroke types and pathogenetic variants of ischemic stroke based on the data obtained from seven regions of the Russian Federation among the population aged 25 years and older. MATERIAL AND METHODS: In total, 29 779 cases of stroke, of which 4167 cases were registered in 2009 and 3402 cases in 2016, were detected during the period from 2009 to 2016. RESULTS AND CONCLUSION: The comparative analysis showed that the proportion of unspecified stroke (unspecified as a hemorrhage and or heart attack) decreased by 11 times from 4.7% to 0.4% (p<0.001). A decrease in 28-day mortality in ischemic stroke, intracerebral and subarachnoid hemorrhage was registered. A change in the ratio of the prevalence of pathogenetic variants of ischemic stroke was revealed. Over the 8-year period, the prevalence of cardioembolic stroke decreased from 35% to 21% (p=0.037). The prevalence of other pathogenetic variants of ischemic stroke has undergone changes. The changes in the ratio of the types of stroke studied are primarily related to the improvement of the diagnosis of stroke types, due to an increase in the percentage of computer tomography/magnetic resonance imaging performed, as well as the introduction of high-tech methods of helping patients with stroke and its effective prevention.
