| Popis: | Introduction Over the last decade, the number of patients with cerebrovascular diseases in Ukraine has grown by 1.5 times. This negative trend is based on the significant increase of vascular risk factors - arterial hypertension, dyslipidemia, sedentary lifestyle, excessive weight/obesity, diabetes mellitus, tobacco smoking, etc. - prevalence among the population of the country, their early development and combination of several vascular risk factors, which makes prevention of cerebrovascular diseases at their early stages a priority. The aim: Study of endothelial vasomotor function in patients with initial symptoms of chronic cerebral ischemia. Material and methods The study included 260 patients of the main group (mean age 50.6±70.9) with initial manifestations of CCI and 30 persons of similar age of the control group. All the patients underwent a clinical neurological examination, MRI of the brain, ultrasonography with the establishment of flow-mediated endotelium-dependent dilatation (FMD) index based on the results of brachial artery compression test, as well as laboratory tests of endothelin-1 and nitrite levels. The patients were subdivided into 3 groups based on their MRI of the brain data: without structural changes of the brain (group 1), with initial vascular structural changes (group 2), with initial structural changes and mild cerebral atrophy (group 3). Results Reliable differences of FMD index were established in the groups with different degrees of structural brain damage, and in comparison with the control group (р 0.9 mm had a significantly lower predetermination to FMD (р=0,001). Statistically significant lower FMD indices were registered in persons with endothelial vasomotor function disorder according to the biochemical markers: with endothelin level increase and nitrite level decrease (р Conclusions An associative link with the presence of endothelial dysfunction according to FMD index were established with different degrees of structural brain damage, with the presence of AH, with ІМC of common carotid arteries >0.9 mm, with endothelial vasomotor function disorder according to the biochemical markers: with endothelin level increase and nitrite level decrease. |
