BBC: Regular exposure to even low levels of air pollution may cause changes to the heart similar to those in the early stages of heart failure, experts say.
A study of 4,000 people in the UK found those who lived by loud, busy roads had larger hearts on average than those living in less polluted areas.
This was despite the fact people in the study were exposed to pollution levels below the UK guidelines.
Researchers called on the government to reduce air pollution more quickly.
“Air pollution should be seen as a modifiable risk factor.”
