During the COVID-19 pandemic, acute stroke alerts in emergency departments decreased by approximately 30%. This reduction in stroke presentations may be due to fewer stroke incidents or patients delaying emergency care.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- The coronavirus disease 2019 (COVID-19) pandemic impacted healthcare systems globally.
- Acute stroke presentations are a critical neurological emergency.
Purpose of the Study:
- To investigate changes in acute stroke presentations during the COVID-19 pandemic.
- To compare stroke alert data from before and during the pandemic surge.
Main Methods:
- Retrospective analysis of stroke alerts from 19 emergency departments in Ohio.
- Comparison of data from a baseline period (Jan 1-Mar 8, 2020) and a COVID-19 period (Mar 9-Apr 2, 2020).
- Statistical analysis using nonparametric methods and Poisson regression.
Main Results:
- A significant decrease of approximately 30% in total daily stroke alerts was observed during the COVID-19 period (rate ratio 0.70).
- Thrombolysis rates also decreased (rate ratio 0.52), while thrombectomy rates remained unchanged.
- Time to presentation, stroke severity, and time to treatment were not significantly different between the periods.
Conclusions:
- The study observed a substantial decline in acute stroke presentations during the COVID-19 pandemic surge.
- This decrease may reflect a true reduction in stroke incidence or patients avoiding emergency care.
- Further research is needed to understand the contributing factors to this observed phenomenon.

Regulation of Stroke Volume
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
