[Ischemic stroke in Europe: incidence trends over three decades (1991-2021)]

Introduction: Ischemic stroke accounts for approximately 80% of all stroke cases and remains a major cause of morbidity and mortality among adults. At the beginning of the 21st century, the age-standardized incidence of stroke in Europe ranged from 95 to 290 cases per 100,000 population. Objective: Our aim was to examine trends in the incidence of ischemic stroke in Europe between 1991 and 2021, by country group, gender, and age group. Method: In our retrospective, quantitative study, we analyzed data from 44 countries in three European country groups (Eastern, Central, and Western Europe) per 100 000 people based on the Global Burden of Disease 2021 database. Descriptive statistics, time series analysis and Kruskal–Wallis test were performed. Results: Between 1991 and 2021, the age-standardized incidence per 100 000 population in men decreased from 206.7 to 147.1 (−28.8%) in Eastern Europe, from 172.1 to 123.8 (−28.1%) in Central Europe, and from 120.7 to 62.3 (−48.4%) (p<0.05) in Western Europe. In women, during the same period, it decreased from 169.8 to 113.9 (−32.9%) in Eastern Europe, from 142.4 to 106.0 (−25.6%) in Central Europe, and from 89.5 to 47.2 (−47.3%) in Western Europe (p<0.05). Significant differences were found between Eastern and Western European countries and between Central and Western European countries for both sexes (1991, 2001, 2011, 2021: p<0.05). The incidence was higher in men than in women every year, especially in the age groups over 55. The largest decrease for both sexes was observed in the 65–69 age group. Based on the analysis by country, the largest decrease was in Portugal (men: –71.1%; women: –69.9%), while in Montenegro, increases of +4.1% for men and +6.3% for women were observed. Conclusion: During the study period, the incidence of ischemic stroke decreased in all three country groups, but the improvement was greater in the Western European country group, which had lower (more favorable) baseline values, than in Central or Eastern Europe. Nevertheless, in 2021, the incidence in Eastern and Central Europe still exceeded the level measured in Western European countries in 1991. Orv Hetil. 2025; 166(42): 1642–1652.
