Key result
Overall Swiss stroke case fatality drops ~54% between 2004 and 2017 despite rising event rates.
Why the study?
The last epidemiologic update of stroke events, mortality, and case fatalities in Switzerland was performed in 2004, since which risk factors, life expectancy, and stroke care have evolved.
Observational (n=1,537,230)
Yes
Absolute Event Rate: 10.5% vs 22.7%
Between 2004 and 2017 in Switzerland, stroke event rates increased but stroke mortality and case fatality rates halved, suggesting improved recognition and treatment.

May reflect improved Swiss stroke care; leaves open whether rising events indicate true incidence increase or better detection.
Hänsel et al. (2025) conducted an observational in Stroke (n=1,537,230). Year 2017 vs. Year 2004 was evaluated on Overall case fatality. Between 2004 and 2017 in Switzerland, the age-standardized stroke event rate increased, but overall case fatality halved from 22.7% to 10.5%.
