Кардиология аспространение метаболического синдрома (МС) во многих странах мира, в том числе в России, приняло характер эпидемии [1]. Анализ раз-личных проспективных исследований свидетельствует о связи между наличием (МС) и смертностью от сер-дечно-сосудистых причин. Существуют данные, что у па-циентов с МС имеется нарушение вариабельности ритма сердца (ВРС), которая позволяет оценить активность раз-личных отделов вегетативной нервной системы и сниже-ние которой является прогностическим маркером смерти при ишемической болезни сердца (ИБС) [2,3]. При этом окончательно не определено, изменения какой активно-сти (симпатической или парасимпатической) являются определяющими в дисфункции вегетативной нервной системы у пациентов с МС.Целью исследования было изучение ВРС во времен-ной области за 24 часа записи электрокардиограммы (ЭКГ) у мужчин с МС без ИБС. (specifically, in LF and VLF parameters) and left ventricular diastolic abnormalities that correlate with abdominal obesity. Материалы и методы
Внутриклеточный метаболизм нейтрофилов и риск развития сахарного диабета 2 типа у больных с метаболическим синдромомКратнов А.Е., Лопатникова Е.Н., Кратнов А.А. ГБОУ ВПОЯрославская государственная медицинская академия, Ярославль (ректор -проф. А.В. Павлов) У 77 мужчин (средний возраст 47±7,4 года) без ишемической болезни сердца были изучены факторы метаболического синдрома, риск развития сахарного диабета 2 типа (СД2) по тесту-опроснику "FINDRISK" и параметры внутриклеточного метаболизма нейтрофилов. Увеличение риска развития СД2 у пациентов с метаболическим синдромом сопровождалось ростом активности миелопероксидазы и содержания пероксида водорода в нейтрофилах, а также увеличением индекса массы тела. У пациентов с выраженным ожирением III степени рост кислородзависимого метаболизма нейтрофилов наблюдался на фоне снижения антиоксидантной защиты в фагоцитах, что может способствовать развитию окислительного стресса. Ключевые слова: метаболический синдром, сахарный диабет 2 типа, нейтрофилы, свободные формы кислорода, антиоксиданты 77 male patients (mean age 47±7.4 years) without ischaemic heart disease were tested for metabolic syndrome factors, risk for development of type 2 diabetes mellitus (T2DM) according to "FINDRISK" questionnaire, following with assessment of intracellular metabolism parameters of neutrophils. Increased risk for T2DM positively correlated in these patients with myeloperoxidase activity, level of hydrogen peroxide within neutrophils and BMI. We observed elevation of oxygen-dependent metabolism in neutrophils form patients with morbid obesity, accompanied with decrease in antioxidant factors, which is suggestive of oxidative stress.
Markers of inflammation and intracellular metabolism of neutrophils were studied in 58 patients with acute coronary syndrome with different levels of troponin T. In patients with repeated coronary events within a year, more pronounced endothelial dysfunction associated with activation of oxygen-dependent metabolism of neutrophils and lipid peroxidation process was revealed at admission to the hospital.
Background: There is a necessity for an establishment of specific markers of oxidative stress for screening in populations of high risk and an estimation of efficiency antioxidative therapies. Objective: Studying the activity of antioxidative enzymes at neutrophils in patients with acute coronary syndrome depending on outcome during the year. Methods: Intracellular metabolism of neutrophils was studied in 108 patients, of whom, in 58 persons has been diagnosed acute coronary syndrome, and 50 individuals were without coronary heart disease. Results: In patients with acute coronary syndrome, in comparison with patients without coronary heart disease, growth of production of superoxide anion on background reduction of glutathione reductase activity in neutrophils was revealed. The greatest reduction in parameters of glutathione reductase and catalase at simultaneous growth of activity of NAD(P)H oxidase and myeloperoxidase at neutrophils was observed in patients with fatal outcome during the year. Conclusion: The decrease of efficiency antioxidative protection of neutrophils associates with risk of fatal outcome in patients with acute coronary syndrome.
Background: Early disturbances of carbohydrate metabolism are an independent risk factor of development of cardiovascular diseases. Objective: The diastolic dysfunction and left ventricle remodeling depending on presence of impaired fasting glucose were examined. Methods: The characteristics of heart remodeling and fasting glucose of capillary blood were studied in 85 men aged 30 to 63 years without coronary heart disease. Results: In male patients with impaired fasting glucose in comparison of persons with level of glucose less than 5.6 mM/l, more pronounced diastolic dysfunction and left ventricle remodeling associated with more often presence III degree of peripheral obesity. Conclusion: Impaired fasting glucose in men increases probability of development of heart remodeling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
