Среди больных ИБС с СН сравнивались группы со сниженной/умеренной и сохраненной фракцией выброса (СНн/уФВ и СНсФВ соответственно). Выявлено статистически значимое увеличение экспрессии микроРНК miR-30c-5p, miR-221-3p и miR-375-3p в PBMC больных СНн/уФВ и СНсФВ в сравнении с группой больных ИБС без СН. Соответственно относительный уровень экспрессии miR 30c-5p в PBMC пациентов СНн/уФВ статистически значимо выше относительно пациентов без СН (P &lt;0,0001). Экспрессия данной микроРНК в PBMC пациентов СНсФВ относительно пациентов без СН статистически значимо выше (P &lt;0,0001). Уровень экспрессии miR-221-3p в PBMC пациентов СНсФВ увеличен в 4,04 раза относительно пациентов без СН (P &lt;0,0001). В PBMC пациентов СНн/ уФВ выявлено увеличение экспрессии miR-221-3p в 2,63 раза (P &lt;0,0001). Экспрессия микроРНК miR-375-3p в PBMC больных СНн/ уФВ и СНсФВ в сравнении с пациентами без СН статистически значимо выше (P &lt;0,0001). Для всех прочих исследуемых микроРНК не было выявлено значимых изменений экспрессии в PBMC. Аналогично нами не было выявлено значимых изменений экспрессии ни для одного из исследуемых генов микроРНК в эпикардиальной жировой ткани больных ИБС.</p><p>Таким образом, полученные данные могут быть использованы для определения роли исследуемых микроРНК в патогенезе СН у больных ИБС.</p></abstract><trans-abstract xml:lang="en"><p>A comparative analysis of the gene expression of microRNAs miR-148b-3p, miR- 30c-5p, miR-221-3p, miR-328-3p, miR-146a-5p, miR-375-3p, miR-22-3p, miR-15b-3p, miR-148a-3p, miR-590-5p in peripheral blood mononuclear cells (PBMC) and epicardial adipose tissue of coronary heart disease (СHD) patients with and without HF (Non-HF) was carried out. Among СHD patients with HF, the groups with mildly reduced/reduced and preserved ejection fraction (HFmr/rEF and HFpEF, respectively) were compared. Our study revealed a significant increase in the expression of miR-30c-5p, miR-221-3p and miR-375-3p mi croRNAs in PBMCs of patients with HFmr/rEF and HFpEF compared with the group of СHD patients without HF. Accordingly, the relative level of miR-30c-5p expression in PBMC of HFF/EFV patients was significantly higher by 1.99 times in comparison with patients without HF (P&lt;0.0001). The expression of this microRNA in PBMC of HFpEF patients relative to patients without HF is significantly higher by 2.94-fold (P&lt;0.0001). The expression level of miR-221-3p in PBMC of HFpEF patients was increased 4.04-fold relative to patients without HF (P&lt;0.0001). A 2.63-fold increase in miR-221-3p expression was detected in PBMC of HFmr/rEF patients (P&lt;0.0001). The expression of miR-375-3p in PBMCs of HFmr/rEF and HFpEF patients compared with Non-HF patients was significantly higher by 2.09- and 1.77 fold (P&lt;0.0001). For all other investigated microRNAs, no significant expression changes were detected in PBMC. Similarly, we did not detect significant expression changes for any of the investigated microRNA genes in the epicardial adipose tissue of CHD patients. Thus, the obtained data can be used to determine the role of the investigated microRNAs in the pathogenesis of HF in СHD patients. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность</kwd><kwd>сохранённая фракция выброса</kwd><kwd>пониженная фракция выброса</kwd><kwd>микроРНК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>preserved ejection fraction</kwd><kwd>reduced ejection fraction</kwd><kwd>microRNA</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда  № 21-75-00065.</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">2021 ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure: Developed by the Task Force for the diagnosis and treatment of acute and chronic heart failure of the European Society of Cardiology (ESC).
