Analysis of epidemiological indicators of recurrent stroke in regions of Russian Federation (On the basis of territorial and population registry 2009-2014)

Introduction. Repeated strokes are the actual problem of modern neurology in mind the severity of clinical symptoms and high mortality. The aims and objectives of the study: The study of epidemiological indicators of recurrent stroke in the Russian regions. Materials and methods. A study of recurrent stroke carried out in the framework of a multi-center study of the epidemiology of stroke in 17 regions of the Russian Federation by the territorial and population registra.Since 2009 to 2014 in the study population reported 36,283 cases of stroke, including recurrent stroke was 8144 cases. It concerned the case of recurrent stroke for stroke, if from the beginning of any previous stroke has been more than 28 types of stroke dney. Diagnostics corresponded with International Classification of Diseases revision 10. After the incidence analysis, mortality, mortality from stroke recurrence. Recurrent stroke prevalence was studied in young age (25-44 years), medium (45-59 years old), the elderly (60-74 years) and old (75 and older), and depending on the type of stroke. In processing the data used statistical software package SAS 8,0. To calculate incidence and smertnostiispolzovalsya method of direct standardization. For standard assumed distribution of the number of men and women by age group for each study area in a year. Changing trends index is determined using the approximation method. Results. The incidence of recurrent stroke in 2009 was 1.09 cases per 1 000 population in 2014 - 0.79 per 1000 population. During the study period there were significant fluctuations in the indicator. Deaths from stroke recurrence showed a decline for the period 2009-2012 gg (0.32; 0.24; 0.20; 0.15 cases per 1,000 population, respectively). The slight increase in the rate recorded in 2013 (0.16) with a decrease in 2014 (0.12), which did not change the trend of decreasing trends. The proportion of ischemic stroke among recurrent stroke was 87.5%, intracerebral hemorrhage - 7.1%, 0.9% subarachnoid hemorrhage, stroke unspecified etiology 4.6%. Prevalence of recurrent stroke among all stroke was 25.5% in 2009. From the period of the study, there were changes in the rate does not exceed 2009. The incidence of recurrent stroke at a young age was 13.2% of cases, on average - 19.1%, in older age - 24.1%, in old - 23.3%. Mortality after repeated insults made; in ischemic insulte - 18.2%, intracerebral hemorrhage - 41.7%, subarachnoid hemorrhage - 34.7%, stroke unspecified etiology - 43.4%. Conclusions. During the period of the study there were changes in the main epidemiological indicators of recurrent stroke in the Russian regions. Despite the emerging positive changes, the problem of recurrent stroke remains relevant.
