Abstract

Background Stroke is the second leading cause of death and disability around the world.

Objective The purpose of this study is to evaluate the age- and sex-specific mortality rates related to stroke in the state of Paraná, Brazil, between 2007 and 2016.

Methods In this cross-sectional study, residents in the state of Paraná were selected by death certificates (from 2007–2016); the basic cause of death was stroke. A descriptive analysis was performed, and mortality rates were calculated with a 95% confidence interval (95% CI) for each year.

Results From 2007 to 2016, there were 62,607 deaths in the state of Paraná due to stroke. Most individuals had medical assistance before death (85.7% in 2007 versus 83.9% in 2016), and most of these deaths occurred in hospitals (73.6% in 2007 versus 74.8% in 2016). Death rates due to stroke increased from 138 (95% CI 135–142) to 163 (95% CI 159–166) per 100,000 inhabitants. This raise occurred mainly in those over 79 years old. For the ages groups of 34 to 44 and 44 to 54 years, mortality rate decreased.

Conclusions In the past 15 years, despite the advances in the diagnosis and treatment of stroke, there has been an increase in mortality due to stroke in the state of Paraná. This fact is possibly associated with the aging of the population because there was a more pronounced increase in the group over 79 years old. Thus, new health strategies are necessary to improve the survival and quality of life of poststroke individuals.

Resumo

Antecedentes O acidente vascular cerebral (AVC) é a segunda principal causa de morte e invalidez em todo o mundo.

Objetivo O objetivo desse estudo é avaliar as taxas de mortalidade específicas por idade e sexo relacionadas ao AVC no estado do Paraná, Brasil, entre 2007 e 2016.

Métodos Neste estudo transversal, foram selecionados residentes no estado do Paraná por certidões de óbito (de 2007–2016); a causa básica da morte foi AVC. Uma análise descritiva foi realizada e as taxas de mortalidade calculadas com intervalo de confiança de 95% (IC 95%) para cada ano.

Resultados De 2007 a 2016, ocorreram 62.607 óbitos no estado do Paraná por AVC. A maioria dos indivíduos teve assistência médica antes do óbito (85,7% em 2007 contra 83,9% em 2016), e a maioria desses óbitos ocorreu em hospitais (73,6% em 2007 contra 74,8% em 2016). As taxas de mortalidade por AVC aumentaram de 138 (IC 95% 135–142) para 163 (IC 95% 159–166) por 100.000 habitantes. Esse aumento ocorreu principalmente em maiores de 79 anos. Para as faixas etárias de 34 a 44 e 44 a 54 anos, a taxa de mortalidade diminuiu.

Conclusões Nos últimos 15 anos, apesar dos avanços no diagnóstico e tratamento do AVC, houve aumento da mortalidade no estado do Paraná. Este fato está possivelmente associado ao envelhecimento da população, pois houve um aumento mais acentuado no grupo acima de 79 anos. Assim, novas estratégias de saúde são necessárias para melhorar a sobrevida e a qualidade de vida dos indivíduos pós-AVC.
