Патогенетические процессы, определяющие развитие ФП, тесно связаны с клеточным метаболизмом, в связи с этим метаболомика представляет собой перспективное направление для поиска новых биомаркеров, изучения метаболических механизмов ФП и определения потенциальных терапевтических мишеней. Материал и методы. В открытое кросс-секционное ретроспективное нерандомизированное выполненное методом параллельных групп исследование включены данные 34 пациентов женского и мужского пола с диагнозом ИБС. Пациенты были распределены на две группы: первая группа состояла из больных ИБС, имеющих ФП (n = 17), вторая ‒ из пациентов с ИБС без ФП (n = 17). Анализ метаболомного профиля проводили методом высокоэффективной жидкостной хроматографии с тандемной масс-спектрометрической детекцией на масс-спектрометре с тройным квадруполем. Результаты и их обсуждение. В общей сложности выявлено 56 метаболитов, по содержанию которых в плазме крови группы пациентов с ФП и без ФП статистически значимо различались. Заключение. Представленные данные указывают на участие ряда метаболитов в энергетическом, аминокислотном и липидном обмене, а также в механизмах воспаления и фиброза. Эти соединения играют значимую роль в патогенезе ФП и могут рассматриваться как потенциальные биомаркеры для диагностики и мониторинга протекания заболевания</p></abstract><trans-abstract xml:lang="en"><p>Despite ongoing efforts, limited understanding of the fundamental causes of atrial fibrillation (AF) continues to hinder progress in its diagnosis and treatment. Pathogenetic processes that determine the development of AF are closely related to cellular metabolism, in this regard, metabolomics is a promising direction for the search for new biomarkers, studying the metabolic mechanisms of AF, and identifying potential therapeutic targets. Material and methods. The open, crosssectional, retrospective, non-randomized parallel group study included data from 34 female and male patients diagnosed with coronary artery disease (CAD). The patients were divided into two groups: the first group consisted of patients with CAD and AF (n = 17), the second ‒ of patients with CAD without AF (n = 17). Metabolomic profiling was performed by high-performance liquid chromatography with tandem mass spectrometric detection on a triple quadrupole mass spectrometer. Results and discussion. In total, 56 metabolites were identified, the content of which in the blood plasma of the groups of patients with and without AF differed statistically significantly. Conclusions. The presented data indicate the involvement of a number of metabolites in energy, amino acid and lipid metabolism, as well as in the mechanisms of inflammation and fibrosis. These compounds play a significant role in the pathogenesis of AF and can be considered as potential biomarkers for the diagnosis and monitoring of the disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>фибрилляция предсердий</kwd><kwd>метаболомика</kwd><kwd>прогностические исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary artery disease</kwd><kwd>atrial fibrillation</kwd><kwd>metabolomics</kwd><kwd>prognostic studies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Анализ методом высокоэффективной жидкостной хроматографии с тандемной масс-спектрометрической детекцией проведен при поддержке государственного задания № FSUS-2025-0012.
