Individuals who have A, B, or AB blood types have an elevated risk of having a heart attack during periods of significant air pollution, compared to those with the O blood type, according to new research from the Intermountain Medical Center Heart Institute and Brigham Young University.
The new study, which was presented at the American Heart Association's 2017 Scientific Sessions in Anaheim, California, is unique in that it links increased risk of heart attack associated with small particulate pollution to increased risk of heart attack for people with certain blood types who have coronary artery disease.
Benjamin Horne, PhD, clinical epidemiologist with the Intermountain Medical Center Heart Institute discusses the research with Jess Gomez.
