Patients prone to heart disease may want to steer clear of air pollution.

A new study shows that the smallest particles from vehicle emissions may be the most damaging components of air pollution linked to heart disease. Researchers found pollutant particles may promote hardening of the arteries by inactivating the protective qualities of so-called "good" cholesterol.

This study appears in the journal Circulation Research.
