Air pollution, climate and cardiac arrest


Sudden cardiac death (SCD) refers to a sudden or unexpected death or arrest attributable to a cardiovascular cause. SCD is estimated to account for 15%–20% of global mortality and the majority of these deaths are out-of-hospital cardiac arrests (OHCAs).1 Despite secular improvements, the incidence of SCD and OHCA remains high and public health strategies to mitigate its risk are critical.

Air pollution and meteorological factors have long been associated with adverse health outcomes.2 Particular matter (PM) with an aerodynamic diameter of 2.5 µm or less (PM2.5) has been of specific interest as these particles are estimated to be small enough to reach pulmonary alveoli.3 Elevations in PM2.5 have been associated with increased cardiovascular mortality and morbidity, including ventricular arrhythmia and heart failure.4 5 In addition to air pollution, meteorological factors such as temperature variability have also been linked to cardiovascular mortality,…
