Key Takeaways
- Stroke accounts for about 5% of the global burden of disease (DALYs)
- In the Global Burden of Disease 2019 study, stroke was the 2nd leading cause of death worldwide
- Subarachnoid hemorrhage accounts for 0.8% of all stroke events globally (2019)
- Mortality after stroke is highest in the first month; a study reported 30-day mortality of 11.6% after first-ever stroke (UK)
- Within 5 years of stroke onset, recurrent stroke occurred in 25% of patients in a systematic review
- Case fatality within 30 days for intracerebral hemorrhage in the US was 35.1% (2014-2018 NIS estimate)
- US indirect costs of stroke were $33.9 billion in 2010 (AHA policy statement)
- Societal cost burden of stroke in the US reached about $45 billion in 2015 (policy analysis estimate)
- In Europe, the cost of stroke care was €45 billion annually (2000-era estimate cited in later policy summaries)
- In GWTG-Stroke, hospitals achieving median door-to-needle time ≤45 minutes reported higher adherence and better outcomes (performance report threshold)
- The American Heart Association’s Get With The Guidelines–Stroke includes performance reporting across >2,000 hospitals in the US (program scale figure)
- In the US, EMS systems achieved stroke center prenotification adoption rates of 70% in quality improvement programs (reported in AHA EMS performance publication)
Stroke causes major worldwide loss of life, with early mortality and preventable recurrence making rapid care and rehab vital.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
