В статье рассмотрены вопросы развития фиброза и иммунного воспаления у больных артериальной гипертензией (АГ) с острым ишемическим инсультом (ИИ) в пожилом возрасте. Цель исследования - изучение возраст-ассоциированных особенностей концентрации маркеров фиброза (металлопротеиназы-9, тканевого ингибитора матриксных металлопротеиназ-1, их соотношения ММП-9/ТИМП-1), иммунного воспаления (TNF-α, IL-1β, INF-γ) у больных АГ с ИИ. В исследование были включены 86 больных АГ II степени, из которых 42 человека - среднего возраста (53±5 лет) и 44 - пожилого (66±5 лет), контрольную группу составили 22 пациента пожилого возраста с АГ без ИИ в анамнезе. Критерии включения - пациенты с АГ, поступившие в стационар в остром периоде первого церебрального инсульта. Установлено, что у пожилых больных АГ с ИИ показатели инфламэйджинга и маркеры фиброза были достоверно выше, чем у лиц среднего возраста. Уровень IL-1β был выше на 31,7 % (р<0,01), TNF-α - на 55,7 % (р<0,001), INF-γ - на 36,6 % (р<0,01), уровень ММП-9 - на 46,4 % (р<0,01), ТИМП-1 - на 21,2 % (р<0,01), ММП-9/ТИМП-1 - на 19,6 % (р<0,01) в пожилом возрасте по сравнению с больными среднего возраста с АГ и острым ИИ. Таким образом, установлено, что больные АГ с ИИ имеют нарушения процессов инфламейджинга, синтеза и деградации внеклеточного матрикса, особенно выраженные в пожилом возрасте. The article deals with the development of fibrosis and immune inflammation in patients with arterial hypertension and acute ischemic stroke in old age. The aim of the study was to study age-associated features of the concentration of fibrosis markers (metalloproteinase-9, tissue inhibitor of matrix metalloproteinases-1, their ratio MMP-9/TIMP-1), immune inflammation (TNF-α, IL-1β, INF-γ) in patients with arterial hypertension and ischemic stroke (AI). The study included 86 patients with arterial hypertension (AH) of the 2nd degree, of which 42 were middle-aged (53±5 years) and 44 elderly (66±5 years). The control group consisted of 22 elderly patients with AH without a history of AI. The criteria for inclusion in the study are patients with hypertension who were admitted to the hospital in the acute period of the first cerebral stroke. It was found that in elderly patients with hypertension with AI, the indicators of inflamaging and fibrosis markers were significantly higher than in middle-aged people. The level of IL-1β was 31,7 % higher (p<0,01), TNF-α by 55,7 % (p<0,001), INF-γ by 36,6 % (p<0,01), the level of MMP-9 was 46,4 % higher (p<0,01), TIMP-1 by 21,2 % (p<0,01), MMP-9/TIMP-1 by 19,6 % (p<0,01) in the elderly compared to middle-aged patients with hypertension and acute AI. Thus, it was found that patients with arterial hypertension and ischemic stroke have violations of the processes of inflamaging, synthesis and degradation of the extracellular matrix, especially pronounced in old age.

58 patients with ischemic stroke were examined (29 young people — the main group and 29 middle-aged people — control group). Among the examined young patients, cardio embolic subtype of stroke prevailed (66 %), and among middle-aged patients was observed in 10 %. The athe rothrombotic subtype of stroke prevailed in middle-aged people (69 %), and among young people — 24 %. The lacunar subtype of stroke in young people was 3 %, and in middle-aged people — 21 %. Patients of young had such subtypes of strokes as hemodyna mic and hemorheological, which respectively equaled 3 %. In middle age these subtypes of strokes were not observed among the examined patients. In young people the proportion of vascular pools with ische mic stroke was: vertebrobasilar — 41 %, carotid prevailed to some extend — 59 %. In middle-aged people the proportion of strokes prevailed in the carotid pool — 64 %, in the vertebrobasilar it was 29 %. Middle-aged people also had a “combined stroke” (stroke that occurred in several pools at once), it amounted to 7 %. As a result, Doppler study of cerebral vessels proved that in young people linear velocity in the right middle cerebral artery was authentically higher compared with middle-aged patients. At the same time, the linear velocity in middle-aged patients was statistically greater in the left vertebral artery. Keywords: ischemic stroke subtypes, young age, hemodynamic parameters
