Air Pollution Particle Size Tied to Higher Stroke Mortality
Poor air quality may increase the risk of in-hospital death among patients with ischemic stroke by up to 24%, depending on the size of air pollution particles, new research shows. Investigators found that mortality risk was highest among ischemic stroke patients who had prolonged exposure to air pollution, especially to small particulate matter (PM), such as soot and smog. The research adds to a growing body of evidence tying air pollution exposure to stroke outcomes and offers new information on the role of PM size in mortality risk.
@laura Data on the type of air pollution and how particle size is involved in stroke have been lacking. To explore that question, researchers used electronic medical records in China to identify more than 3.1 million hospitalizations for ischemic and hemorrhagic stroke; 32,140 people, or 1%, died of stroke while hospitalized.
