Оценить взаимосвязь маркеров фиброза со структурнофункциональными показателями у  пациентов с  различными вариантами гипертрофической кардиомиопатии (ГКМП).</p></sec><sec><title>Материал и  методы</title><p>Материал и  методы. В  проспективном сравнительном нерандомизированном исследовании участвовали 49 пациентов с  ГКМП. Пациенты были разделены на 3 группы по вариантам течения заболевания: 1 группа — стабильное течение (n=12; из них 8 (67%) мужчин, средний возраст ‒ 41±12 лет); 2 группа  — прогрессирующее течение (n=26; из них 16 (61%) мужчин, средний возраст ‒ 57±11 лет); 3 группа — пациенты с фибрилляцией предсердий (ФП) (n=11; из них 4 (36%) мужчин, средний возраст ‒ 63±6 лет). Пациентам были проведены стандартные клинико-лабораторные и  инструментальные исследования. Всем пациентам с  помощью иммуноферментного анализа в  сыворотке крови определяли уровни матриксной металлопротеиназы-9 (MMП-9) и  тканевого ингибитора матриксных металлопротеиназ-1 (ТИМП-1).</p></sec><sec><title>Результаты</title><p>Результаты. У  пациентов с  ГКМП всех вариантов течения отмечаются повышенные уровни MMП-9 и ТИМП-1 по сравнению с референсными значениями. В 1 группе уровень ММП-9 (Ме (Q1;Q3)) составил 226 (201;271) нг/мл; ТИМП-1 ‒ 410 (267;488) нг/мл; во 2 группе уровень ММП-9 составил 236 (187;285) нг/мл; ТИМП-1 ‒ 421 (321;499) нг/мл. При варианте течения с  ФП уровень ММП-9 составил 260 (228;296) нг/мл, а  уровень ТИМП-1 ‒ 381,5 (305;466) нг/мл, статистически значимого различия не достигнуто (р=0,59; р=0,90, соответственно). Обнаружена корреляция между возрастом и уровнем ММП-9, а также между уровнем ММП-9 и объемом левого предсердия (р=0,034; p=0,035, соответственно).</p></sec><sec><title>Заключение</title><p>Заключение. Высокая активность матриксных металлопротеиназ и их тканевых ингибиторов отражает усиленный фиброз и ремоделирование миокарда при ГКМП, особенно характерное для пациентов с вариантом ФП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the relationship between fibrosis markers and structural and functional parameters in patients with various types of hypertrophic cardiomyopathy (HCM).</p></sec><sec><title>Material and methods</title><p>Material and methods. This prospective comparative non-randomized study included 49 patients with HCM. Patients were divided into 3 groups according to the disease course: group 1  — stable course (n=12; men, 8 (67%), mean age ‒ 41±12 years); group 2 — progressive course (n=26; men, men, 16 (61%). mean age — 57±11 years); group 3 — patients with atrial fibrillation (AF) (n=11; men, 4 (36%), mean age — 63±6 years). Patients underwent standard clinical and paraclinical investigations. The levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) were determined in all patients using enzyme-linked immunosorbent assay in blood serum.</p></sec><sec><title>Results</title><p>Results. In all patients with HCM, elevated levels of MMP-9 and TIMP-1 are noted compared to the reference values. In group 1, the MMP-9 level [Me (Q1; Q3)] was 226 (201;271) ng/ml; TIMP-1 — 410 (267;488) ng/ml; in group 2, the MMP-9 level was 236 (187;285) ng/ml; TIMP-1 — 421 (321;499) ng/ml. In the course with AF, the MMP-9 level was 260 (228;296) ng/ml, while TIMP-1 — 381,5 (305;466) ng/ml; no significant difference was revealed (p=0,59; p=0,90, respectively). A correlation was found between age and MMP-9 levels, as well as between MMP-9 levels and left atrial volume (p=0,034; p=0,035, respectively).</p></sec><sec><title>Conclusion</title><p>Conclusion. The high activity of matrix metalloproteinases and their tissue inhibitors reflects enhanced fibrosis and myocardial remodeling in HCM, which is especially characteristic of patients with AF.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипертрофическая кардиомиопатия</kwd><kwd>матриксная металлопротеиназа-9</kwd><kwd>миокардиальный фиброз&#13;
