Air pollution-related hospitalization for chest pain, heart attack differed by seasons

Short-term increases in fine particulate air pollution (PM2.5) during the summer and winter months in a mountain valley region of Utah were associated with increased health care visits for heart attack and unstable chest pain; however, the risk for each cardiac event differed by season, according to a preliminary study to be presented at the American Heart Association’s Scientific Sessions 2023. The meeting, to be held Nov. 11–13, in Philadelphia, is a premier global exchange of the latest scientific advancements, research and evidence-based clinical practice updates in cardiovascular science.
