Endothelial Function in Patients with Migraine without Aura during the Interictal Period.

Background: In most of the studies, the association of vascular events is limited to migraine with aura or it is stronger in this group, whereas the link between migraine without aura (MO) and vascular events remained uncertain. Therefore, we decided to evaluate endothelial function by chemical and functional markers of endothelium in MO and compare with normal population.

Methods: In this study, 39 patients and 25 healthy subjects were enrolled and flow-mediated dilatation (FMD), C-reactive protein (CRP), nitrite and nitrate were measured in these two groups.
