Exposure to air pollution, traffic noise raises odds of heart failure

Long‐term exposure to air pollution and traffic noise is associated with an elevated risk for developing heart failure, according to new data published in the Journal of the American Heart Association.

“We found that long-term exposure to specific air pollutants and road traffic noise increased the risk of incident heart failure, especially for former smokers or people with hypertension, so preventive and educational measures are necessary,” said lead author Youn-Hee Lim, PhD, assistant professor in the section of environmental health within the department of public health at the University of Copenhagen in Copenhagen, Denmark, in a prepared statement. “To minimize the impact of these exposures, broad public tactics such as emissions control measures should be implemented. Strategies like smoking cessation and blood pressure control must be encouraged to help reduce individual risk.”

Researchers examined the impact of long-term environmental exposure, explicitly from air pollution and road traffic noise, on the development of heart failure in 22,000 female nurses, 44 years of age and older, over a 15- to 20-year period. Participants were recruited in 1993 or 1999.

Data was from the Danish Nurse Cohort study.

In the analysis, exposure to small particulate matter and road traffic noise over three years was linked with an increased risk for HF.

The risks were highest among women who were former smokers or who had high blood pressure.
