Air pollution increases the risk of heart failure: Study

A new study conducted in Italy has identified a dose-response relationship between daily pollutant concentrations and the incidence of cardiac arrest outside the hospital. The research is presented at the ESC Congress 2021.

The research findings were presented at the ESC Congress 2021. “We studied seven common pollutants and found that as the concentration of each rosehip increased, the risk of heart failure increased,” said study author Dr. Francesca R. Gentile said. Matteo Foundation, Pavia, Italy.

“The findings suggest that air quality should be incorporated into predictive models to assist health systems in planning service requirements,” said Dr Gentile. Air pollution has been established as a potential trigger of cardiac arrest outside the hospital, but the association with specific air pollutants remains controversial due to the number of mechanisms involved. This study examined the relationship between short-term exposure to particulate and gaseous pollutants and the incidence of out-of-hospital cardiac arrest.

The study was conducted in the provinces of Pavia, Lodi, Cremona and Mantua in southern Lombardy, which covers 7,863 km2 in metropolitan and rural areas with more than 1.5 million residents. Data on the daily incidence of cardiac arrest in 2019 were obtained from the regional cardiac arrest registry Lombardia Care. Information on the daily concentrations of particulate matter (PM10, PM2.5), nitrogen dioxide, carbon monoxide, benzene, sulfur dioxide and ozone in the study area was provided by the regional Environmental Protection Agency (ARPA).
