Air Pollution As a Stroke Risk?

A recent study out of Texas has shown an association between ischemic strokes and exposure to air pollution.

The study was performed as a follow up to other studies which showed that exposure to air pollution in the form of particulate matter is associated with adverse changes in blood flow, which in turn are thought to enhance the potential for blood clot formation. Although the study focused on fine particulate matter, the association of ozone levels and stroke/TIA risk suggests that ambient air pollution in general may affect stroke risk.

However, the results of the study only show a weak increased risk and are not statistically significant. This makes a repeat study to confirm the results a requirement before the data can be fully accepted as truth. So don't move to the woods just yet; a few more studies need to be done before these results are confirmed.
