Air and Noise Pollution Linked to Increased Heart Failure

Oct. 22, 2021 — Exposure to air pollution and road traffic noise over several years may increase the risk of heart failure, according to new research from a large observational study.

The study examined more than 22,000 female nurses based in Denmark, aged 44 and older, over a period of 15 to 20 years to evaluate the impact of exposure to small particulate matter and nitrogen dioxide, as well as road traffic noise.
