Less air pollution less heart attack – study shows

According to medical news today – at 2021 virtual conference of the American Heart Association (AHA), scientists will present preliminary evidence that reduced air pollution in the U.S. resulting from 2020 COVID-19 lockdowns correlated with a lower incidence of heart attacks.

Previously a study by researchers at the University of Washington revealed a direct link between air pollution and atherosclerosis, which is a buildup of plaque in the coronary artery that can affect heart health.

Minuscule particles such as PM2.5, which are released through the burning of fossil fuels in motor vehicles, factories, and power plants, are an established risk factor for the most severe form of heart attack, known as an ST-elevation myocardial infarction (STEMI).
