Car pollution, heart attack link

Exposure to high levels of traffic pollution among people with heart or lung disease is associated with reduced heart rate variability, a risk factor for sudden cardiac death.

Exposure to high levels of traffic air pollution among people with heart or lung disease is associated with reduced heart rate variability (HRV), a risk factor for sudden cardiac death, finds a new study.

The study appears in the July issue of the Journal of Occupational and Environmental Medicine. (- HealthDay News, July 2010)
