We have speculated that PM causes a large portion of the acute CV effects that occur within hours as a consequence of rapid autonomic imbalance
, whereas those observed at a later time period ([greater than or equal to] 1 day postexposure) are more likely prompted by additional and/or separate slower-acting pathways such as inflammation and oxidative stress-induced endothelial dysfunction (Brook and Rajagopalan 2009).

This autonomic imbalance
implies a failure in the adaptation to stressors that may predispose to the development of a sustained perturbation of sympathovagal balance over time, possibly with higher risk of developing hypertension.
