Years of exposure to air pollution and road traffic noise may increase the risk of heart failure

Exposure to air pollution and road traffic noise may increase the risk of heart disease for many years, and the association seems to be greater in people who have ever smoked or have high blood pressure, according to the latest research published in the journal of the American Heart Association, American Heart Association An open access magazine

"We found that long-term exposure to specific air pollutants and road traffic noise can increase the risk of heart failure, especially for people who have quit smoking and hypertension, so preventive and educational measures are necessary

This analysis investigated the effects of long-term exposure to the environment, especially air pollution and road traffic noise, on the development of heart failure in a group of female nurses in Denmark over a period of 15 to 20 years

The researchers collected data from a prospective study involving more than 22,000 members of the Danish all-female nurse cohort study

The research team lives in rural, urban and suburban Denmark

Analysis of various pollutants and their effects on sudden heart failure found:

• Within three years, for every increase of 5.

  
  

• Every 8.

  
  

• In three years, for every 9.

  
  

• People who have increased exposure to fine particles and who have smoked have a 72% increased risk of heart failure

  
  

"We were surprised by the interaction of two environmental factors-air pollution and road traffic noise," Lim said

This study has several limitations

Previous studies have shown that there is a link between air pollution and cardiovascular disease
