Key Points

This research aims to investigate the relationship between short-term PM2.5 exposure and stroke severity and etiology.
Analyzed stroke data over two years focusing on PM2.5 exposure levels, severity at presentation, and stroke subtypes.
Measured frequency of hemorrhagic strokes on high PM2.5 days.
Evaluated the persistence of stroke severity effects up to 48 hours post-exposure.
Short-term PM2.5 exposure was linked to greater stroke severity at the time of presentation.
A significant correlation was found between high PM2.5 days and increased frequency of hemorrhagic strokes.
PM2.5 exposure was independently associated with the large-artery stroke subtype.

Implication

Links high particulate matter exposure to increased stroke severity and subtype in individuals, indicating potential health risks.

Abstract

Short-term PM2.5 linked to higher stroke severity at presentation. High PM2.5 days was correlated with increased hemorrhagic stroke frequency. PM2.5 independently associated with large-artery stroke subtype. Stroke severity effects persisted up to 48 hours after exposure.
