Even moderate air pollution linked to subclinical cardiac damage, RSNA news reports

A British study finds that exposure to moderate levels of air pollution — well below regulatory limits — is associated with subclinical heart damage resembling early heart failure, as seen on cardiac MRI (exact effect size not reported in source).

• The study used cardiac MRI to detect early myocardial changes in a general-population sample; exact sample size not provided in the snippet.
• The primary finding is a dose-response association between common air pollutants (PM2.5, NO2) and adverse cardiac remodeling.
• Limitation: The source is a news summary of a study presentation; full methodology, numbers, and peer-reviewed publication details are not yet available.
