Ultrasound assessment of endothelial dysfunction in Egyptian migraine patients
Abstract
Abstract Background It becomes clearer that migraine is associated with vascular risks; however, preclinical vascular involvement is not sufficiently addressed. Evidences point that migraine attacks affect vascular endothelium. The aim of this study was to investigate endothelial dysfunction in migraineurs through assessment of carotid intima-media thickness (CIMT) and flow-mediated dilatation (FMD) of the brachial artery and their correlation with clinical characteristics of migraine, headache severity, and brain magnetic resonance imaging (MRI) findings. Results A statistically significant difference was found between migraineurs and controls where carotid IMT was significantly higher and FMD of the brachial artery was significantly lower in migraineurs compared to controls. Carotid IMT was significantly higher and FMD was significantly lower in chronic migraine compared to episodic migraine patients. Mean IMT values were significantly higher in patients receiving ergots and in patients with subcortical white matter lesions in brain MRI. Mean FMD values were significantly lower in patients receiving ergots. There was a significant negative correlation between FMD and carotid IMT, age of the patients, disease duration, duration of headache attacks, headache frequency, and migraine disability assessment questionnaire (MIDAS) score. There were significant positive correlations between carotid IMT and age of patients, disease duration, headache frequency, MIDAS score, and…
