Oxidative stress and systemic inflammation as modifiers of cardiac autonomic responses to particulate air pollution.

BACKGROUND The role of oxidative stress and systemic inflammation on the association between personal exposures to ambient fine particulate matter ≤ 2.5 μm in diameter (PM2.5) and cardiac autonomic dysfunction, indicated by reduction in heart rate variability (HRV), has not been examined. METHODS We performed a repeated measures study on community adults… (More)
