Sourced Air Pollution, Heat Waves Together Linked to Higher CV Mortality Risk
A multicountry study published in JACC reveals that combined exposure to fire-sourced air pollution and heat waves significantly increases the risk of cardiovascular mortality. The findings indicate that these climate-related hazards have a synergistic effect that is more dangerous than either hazard alone.
Combined exposure to substantial fire-sourced air pollution (SFAP) and heat waves was associated with a higher excess risk of cardiovascular mortality than exposure to either hazard alone, according to a multicountry time-series study published July 29 in JACC . The findings suggest that evaluating landscape fire smoke and heat waves as separate hazards may underestimate short-term cardiovascular mortality risk.
