Impact of fine particulate matter (PM2.5) exposure during wildfires on cardiovascular health outcomes
Impact of fine particulate matter (PM2.5) exposure during wildfires on cardiovascular health outcomes
Epidemiological studies investigating the role of fine particulate matter (PM2.5; aerodynamic diameter <2.5 lm) in triggering acute coronary events, including out-of-hospital cardiac arrests and ischemic heart disease (IHD), during wildfires have been inconclusive. The researchers examined the associations of out-of-hospital cardiac arrests, IHD, acute myocardial infarction, and angina (hospital admissions and emergency department attendance) with PM2.5 concentrations during the 2006–2007 wildfires in Victoria, Australia, using a time-stratified case-crossover study design.
