Relationship between 24-h air pollution, emergency department admission and diagnosis of acute coronary syndrome

摘要

Current available evidence suggests that air pollution, especially particulate matter 50 μg/m3 (2.4 ± 0.2 vs. 1.9 ± 0.2; P = 0.03). A statistically significant association was also observed between 24-h PM10 levels and daily number of ACS diagnoses (r = 0.26; P < 0.001), but not between 24-h PM10 levels and daily ED accesses for suspected ACS (r = 0.12; P = 0.24). Taken together, these results support the existence of an epidemiologic association between air pollution and acute cardiovascular events.
