Abstract
in English, Spanish

Background: Stroke is the second cause of death and the first cause of disability in Europe. The number of stroke patients shows a rapidly increasing due to the increase in the elderly population. The aim of this meta-analysis is to evaluate the prevalence and incidence of stroke in Europe.

Method: We conducted a literature search in MEDLINE, SCOPUS, CINAHL Complete and EMBASE, using the keywords "stroke", "cerebrovascular accident", "epidemiology", "prevalence", "incidence" and "Europe". In order to evaluate the quality and risk of bias, we used the Hoy's modified scale for prevalence studies and the Newcastle Ottawa Scale for incidence studies. A random effects model with 95% confidence intervals (95%CI) was used for the meta-analysis. The I2 statistic was applied to assess heterogeneity.

Results: The prevalence of stroke in Europe adjusted for sex was estimated at 9.2% (95%CI: 4.4-14.0). The prevalence was 9.1% (95%CI: 4.7-13.6) in men and 9.2% (95%CI: 4.1-14.4) in women, and increased with age. The incidence of stroke in Europe adjusted for sex was 191.9 per 100,000 person-years (95%CI: 156.4-227.3); it was 195.7 per 100,000 person-years (95%CI: 142.4-249.0) in men and 188.1 per 100,000 person-years (95%CI: 138.6-237.7) in women. Again, these rates increased with age.

Conclusion: The prevalence of stroke in Europe is 9.2%. The incidence of stroke in Europe is 191.9 per 100,000 person-years. The prevalence of stroke has increased, whereas the incidence of stroke is stable in comparison with studies conducted at the beginning of the 21st century.

Fundamento:: El ictus es la segunda causa de muerte y la primera causa de discapacidad en Europa. El número de pacientes con ictus muestra una tendencia de crecimiento rápido debido al aumento de la población anciana. El objetivo de este metaanálisis es estimar la prevalencia e incidencia de ictus en Europa.

Método:: Se buscaron artículos en las bases de datos MEDLINE, SCOPUS, CINAHL Complete y EMBASE con los términos “stroke”, “cerebrovascular accident” combinadas con “epidemiology”, “prevalence”, “incidence” y “Europe”. La calidad y el riesgo de sesgo se analizó con las escalas Hoy modificada y Newcastle Ottawa para los artículos de prevalencia e incidencia, respectivamente. El metaanálisis utilizó un modelo de efectos aleatorios con intervalos de confianza del 95% (IC95%) y el estadístico I2 para estimar la heterogeneidad.

Resultados:: La prevalencia de ictus en Europa ajustada por sexo fue 9,2% (IC95%: 4,4-14,0); en hombres fue 9,1% (IC95%: 4,7-16,6) y en mujeres 9,2% (IC95%: 4,1-14,4); se encontró una tendencia creciente con el aumento de la edad. La incidencia de ictus ajustada por sexo fue 191,9 por 100.000 personas-año (IC95%: 156,4-227,3); en hombres fue de 195,7 por 100.000 personas-año (IC95%: 142,4-249,0) y en mujeres 188,1 por 100.000 personas-año (IC95%: 138,6-237,7), con igual tendencia creciente con el aumento de la edad.

Conclusiones:: La prevalencia de ictus en Europa alcanza un 9,2%. La incidencia se sitúa en 191,9 por 100.000 personas-año. La prevalencia de ictus ha aumentado mientras que la incidencia se mantiene estable en comparación con estudios realizados a comienzos del siglo XXI.
