Prevalence of recurrent stroke in different age groups

Abstract

The aim of the research is to study and to analyze the prevalence of recurrent strokes in the Russian regions included in Federal program from 2009 to 2016 on reorganization of care for patients with stroke in different age groups. Material and methods. The research method is territory and population register. The study included seven territories with 7124 of cases of recurrent stroke in total. The examined patients were divided into four age groups: of young age - 25-44 years old; of average age - 45-59 years old; of old age - 60-74 years old, and of senile - 75 years and older. Statistical analysis was carried out using programming language for statistical calculations R version 3.3.2. Results. The maximum number of recurrent stroke cases was registered in old age (46.6%), and the minimum number of cases of recurrent stroke was among young people (2.4%). When analyzing the incidence of recurrent strokes, depending on the year, the most systematic percentage decrease of recurrent strokes was observed among elderly people. The highest percentage of recurrent strokes was determined among the elderly people in 2013 - 26.38%; and the lowest percentage of recurrent strokes was recorded among young people. Conclusion. Among the surveyed age groups statistically significant decrease in recurrent strokes among young, middle-aged and elderly people was revealed during 2009 - 2016. It is the criterion for the effectiveness of recurrent stroke prevention conducted in the studied areas. There was no statistically significant decrease in the prevalence of recurrent stroke among elderly people by 2016. It indicates that the prevention of recurrent strokes in old age is a difficult task due to concomitant diseases and associated pathology in these patients.
