Ambient Air Pollution and Out-of-Hospital Cardiac Arrest in Beijing, China.

ABSTRACT: Air pollutants are associated with cardiovascular death; however, there is limited evidence of the effects of different pollutants on out-of-hospital cardiac arrests (OHCAs) in Beijing, China. We aimed to investigate the associations of OHCAs with the air pollutants PM_2.5-10 (coarse particulate matter), PM_2.5 (particles ≤2.5 μm in aerodynamic diameter), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), carbon monoxide (CO), and ozone (O₃) between 2013 and 2015 using a time-stratified case-crossover study design. We obtained health data from the nationwide emergency medical service database; 4720 OHCA cases of cardiac origin were identified. After adjusting for relative humidity and temperature, the highest odds ratios of OHCA for a 10 μg/m³ increase in PM_2.5 we
