In accordance with that, we have conducted two studies to assess whether migraine patients have systemic or just isolated cerebral
endothelial dysfunction  and . The methods of cerebrovascular reactivity (CVR) to l-arginine and flow-mediated vasodilatation selleck kinase inhibitor (FMD) were used to assess the anterior and posterior cerebral and systemic endothelial function , , , , , ,  and . We also measured carotid IMT, gathered medical history, performed physical and neurological examinations, as well as ran clinical laboratory tests. Only migraine patients without comorbidities and with normal IMT were included. In our first study we have shown that migraine patients without comorbidities, both with or without aura, might have intact systemic endothelial function . In our second study we have found reduced vasodilatatory capacity in the territory of the posterior cerebral artery (PCA), and intact in the territory of the middle cerebral artery (MCA) which could indicate impaired cerebral endothelial function in the posterior cerebral circulation in migraine patients without comorbidities . The aim of this post hoc study was to evaluate whether impaired endothelial function of the posterior cerebral circulation and intact endothelial function of the anterior cerebral and systemic circulation are associated with migraine. These
comparisons have not yet been performed. This post hoc study was performed using data obtained from our two previous studies, which this website were approved by the National Medical Ethics Committee of the Republic of Slovenia. Forty migraine patients and twenty healthy subjects participated. All subjects gave written informed consent before being included in the study. Migraine patients were diagnosed according to the International Headache Society criteria (2nd edition) . Healthy subjects were randomly selected
from hospital staff and acquaintances after completing a questionnaire. Migraine patients were randomly selected from a headache clinic. All subjects had a normal somatic and neurological examination. Migraine patients were divided into two groups, 20 patients with migraine with aura (MwA), and 20 patients Methane monooxygenase without aura (MwoA). The three groups were matched for gender and age. None of the subjects in the control group were suffering from headache when the study was conducted, and none had migraine or other headache. Migraine patients had the last migraine episode more than 24 h before the investigations were conducted. The major exclusion criteria were: history of cardiovascular disease, arterial hypertension (systolic blood pressure (SBP) > 140 mmHg or diastolic blood pressure (DBP) > 90 mmHg), body mass index (BMI) < 18 and ≥25 kg/m2, hypercholesterolemia (total cholesterol > 5.5 mmol/L), diabetes, IMT > 1.
