The data obtained suggest that a local increase of endothelial inflammatory mediator expression correlates with the clinical setting of thromboembolic ischemia and may play a role in conversion of atheromatous plaque to a prothrombotic state. The data also indicate that this line of investigation deserves further exploration because it may be useful in identifying new mechanisms in patients at risk for stroke and in suggesting possible novel strategies for intervention. %U //www.ez-admanager.com/content/neurology/49/5_Suppl_4/S15.full.pdf
