В исследование включены 42 пациента (м/ж 28/14) в возрасте 53–72 года с ИБС, подвергнутых операции аортокоронарного шунтирования. Материалом для исследования явились адипоциты ЭЖТ, полученные энзиматическим методом из интраоперационных эксплантов. Определяли базальные уровни гликемии, инсулинемии, С-пептида, показатели липидтранспортной функции крови, содержание адипокинов и вчСРБ в сыворотке крови. Медианы показателей размера адипоцитов ЭЖТ и доли адипоцитов ЭЖТ более 100 мкм составили 87,32 мкм и 14,64% соответственно. Общая выборка пациентов разделена на две группы: со средним размером адипоцитов ЭЖТ менее или равным 87,32 мкм (группа 1) и более 87,32 мкм (группа 2). В группе 2 определялись более высокие значения индекса массы тела, окружностей талии и бедер, содержания триглицеридов, вчСРБ и более низкий уровень адипонектина, а медиана доли гипертрофированных адипоцитов была в три раза выше, чем в группе 1. Построена модель множественной логистической регрессии, согласно которой статистически значимыми детерминантами выраженной гипертрофии адипоцитов ЭЖТ являются снижение уровня адипонектина, рост вчСРБ и С-пептида, который отражает биосинтез и секрецию инсулина. Прогностическая точность модели составила 82%, чувствительность – 85%, специфичность – 79%, AUC = 0,89.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты свидетельствуют о тесной взаимосвязи между развитием гипертрофии адипоцитов ЭЖТ, нарушением продукции адипонектина, инсулина и процессами воспаления, причем концентрации адипонектина, вчСРБ и базального С-пептида в крови являются биомаркерами, с высокой точностью определяющими наличие гипертрофии адипоцита ЭЖТ.</p></sec></abstract><trans-abstract xml:lang="en"><p>The changes of epicardial adipose tissue’s (EAT) morphofunctional characteristics represent an important factor of cardiometabolic impairments development. However, factor data determining the severity of EAT adipocytes’ hypertrophy in patients with coronary atherosclerosis are absent in literature.</p><sec><title>Aim</title><p>Aim: To compare the size of the EAT adipocyte and the percentage of hypertrophied adipocytes with the parameters of glucose/insulin metabolism, blood lipid transport function, adipokines’ profile and serum levels of high sensitive C-reactive protein (hsCRP) in patients with chronic coronary artery disease (CAD) undergoing coronary artery bypass grafting (CABG); to establish statistically significant determinants of a pronou ced degree of EAT adipocytes’ hypertrophy.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 42 patients (m/f 28/14) aged 53–72 y.o. with CAD, who underwent CABG. The material for the study was EAT adipocytes obtained by the enzymatic method from intraoperative explants. The basal blood levels of glycemia, insulinemia, C-peptide, blood lipid transport function, adipokines and hsCRP were determined. The median indicators of the size of EAT adipocytes and the proportion of EAT adipocytes over 100 μm were 87.32 μm and 14.64%, respectively. The total sample of patients was divided into two groups: gr. 1 with an average size of EAT adipocytes less than or equal to 87.32 μm and gr. 2 with an average size of EAT adipocytes more than 87.32 μm. Gr. 2 had higher body mass index, waist and hip circumferences, triglycerides, hsCRP, and lower adiponectin levels, while the median proportion of hypertrophied adipocytes was three times higher than in group 1. A model of multiple logistic regression was constructed, according to which statistically significant determinants of the pronounced EAT adipocytes’ hypertrophy are represented by the decreased level of adiponectin, and increased concentrations of hsCRP and C-peptide, which reflects the biosynthesis and secretion of insulin. The predictive accuracy of the model was 82%, sensitivity 85%, specificity 79%, AUC = 0.89.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our results indicate a close correlation between the development of EAT adipocytes hypertrophy, impaired production of adiponectin, insulin, and inflammation processes. Concentrations of adiponectin, hsCRP, and basal C-peptide in the blood are biomarkers that accurately determine the presence of EAT adipocyte hypertrophy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эпикардиальная жировая ткань</kwd><kwd>адипоциты</kwd><kwd>адипонектин</kwd><kwd>высокочувствительный С-реактивный белок</kwd><kwd>С-пептид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epicardial adipose tissue</kwd><kwd>adipocytes</kwd><kwd>adiponectin</kwd><kwd>hsCRP</kwd><kwd>C-peptide</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках темы фундаментальных исследований № 122020300043-1; в работе использовано оборудование Центра коллективного пользования «Медицинская геномика».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was carried out within the framework of the topic of fundamental research no. 122020300043-1; the work was performed using the equipment of the Center for Collective Use “Medical Genomics”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Iacobellis G.
