The Effects of Air Pollution on Ischemic Stroke Admission Rate

다국어 초록 (Multilingual Abstract)

The present study aimed to determine the relationship between the level of air pollutantsand the rate of ischemic stroke (IS) admissions to hospitals. In this retrospectivecross-sectional study, stroke admissions (January-March 2012 and 2013) to an emergencydepartment and air pollution and meteorological data were gathered. The relationshipbetween air pollutant levels and hospital admission rates were evaluated usingthe generalize additive model. In all 379 patients with IS were referred to the hospital(52.5% male; mean age 68.2±13.3 years). Both transient (p＜0.001) and long-term(p＜0.001) rises in CO level increases the risk of IS. Increased weekly (p＜0.001) andmonthly (p＜0.001) average O3 levels amplifies this risk, while a transient increase inNO2 (p＜0.001) and SO2 (p＜0.001) levels has the same effect. Long-term changes inPM10 (p＜0.001) and PM2.5 (p＜0.001) also increase the risk of IS. The findings showedthat the level of air pollutants directly correlates with the number of stroke admissionsto the emergency department.
