To study the role of blood biomarkers in predicting death from cardiovascular events in patients with heart failure with reduced ejection fraction (HFrEF) within one year after cardioverter defibrillator (ICD) implantation.</p></sec><sec><title>Material and methods</title><p>Material and methods. This one-center observation study included 384 HFrEF patients (men, 84%, NYHA class III – 74%, NYHA class IV – 7%), who underwent prospective observation for 1 year after ICD implantation. The study of the original panel of modern biomarkers (blood electrolytes, C-reactive protein, creatinine, soluble growth stimulation expressed gene 2 (sST2), N-terminal pro-brain natriuretic peptide (NT-proBNP), galectin-3), allowing to evaluate HF pathogenesis was conducted. Based on the blood creatinine concentration, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula was used to estimate the glomerular filtration rate (GFR).</p></sec><sec><title>Results</title><p>Results. In a one-year observation, the primary endpoint was recorded in 35 patients (11%). Single-factor logistic regression showed 3 biomarkers with the greatest predictive potential (p&lt;0,01), related to the occurrence of the investigated endpoint. The concentration of potassium and NT-proBNP, the GFR (CKD-EPI) was included in the multi-factor predictive model with diagnostic efficiency of 68% (sensitivity of 60%, specificity 71%). It was shown that the cardiovascular death risk increased by 2,64 (OR=2,64; 95% CI: 1,28-5,46; p=0,007) at GFR &lt;60 ml/min/1,73 m2 and increased by 3,32 (OR=3,32; 95% CI: 1,26-8,73; p=0,012) at NT-proBNP &gt;2000 pg/ml.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study of blood biomarkers is promising and in demand for the prediction of adverse outcomes of HF. According to the data obtained, the factors «GFR &lt;60 ml/min/1,73 m2» and «NT-proBNP &gt;2000 pg/ml» may be relevant for one-year mortality prediction.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: изучение роли биомаркеров крови в  прогнозировании наступления смерти вследствие острой декомпенсации сердечной недостаточности (ОДСН) у больных хронической сердечной недостаточностью со сниженной фракцией выброса (ХСНнФВ) в течение года после имплантации кардиовертера-дефибриллятора (ИКД).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровое наблюдательное исследование было включено 319 больных ХСНнФВ (мужчины 83%, ХСН 3 функционального класса [ФК] - 74%, ХСН ФК 4 – 7%), подвергнувшиеся  проспективному наблюдению в течение 1 года после имплантации ИКД. Проведено изучение оригинальной панели современных биомаркеров (электролиты крови, С-реактивный белок, креатинин, растворимый стимулирующий фактор роста (sST-2), мозговой натрийуретический пептид (NT-proBNP), галектин-3), позволяющих оценить основные механизмы патогенеза ХСН. На основании концентрации креатинина крови проводился  расчет скорости клубочковой фильтрации (СКФ) по формуле CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration).</p></sec><sec><title>Результаты</title><p>Результаты. В ходе однолетнего наблюдения первичная конечная точка была зарегистрирована у 35 больных (11%). При однофакторной логистической регрессии выделено 3 биомаркера с наибольшим прогностическим потенциалом (р&lt;0,01), связанных с возникновением исследуемой конечной точки. Концентрация калия крови и NT-proBNP, величина СКФ (CKD-EPI) вошли в состав многофакторной прогностической модели с диагностической эффективностью составила 66% (чувствительность 66%, специфичность 68%). Было показано, что риск смерти по причине ОДСН повышался в раза в 2 раза (ОШ=2,4; 95% ДИ: 1,14-4,88; р=0,018) при СКФ &lt;60 мл/мин/1,73 м2 и возрастал почти в 3 раза (ОШ=2,6; 95% ДИ: 1,05-6,66; р=0,035) при концентрации NT-proBNP &gt;2000 пг/мл.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование бимаркеров крови является перспективным и востребованным для прогноза неблагоприятных исходов ХСН. Согласно полученным данным, факторы «СКФ &lt;60 мл/мин/1,73 м2»  и «NT-proBNP &gt;2000 пг/мл» могут иметь значение для определения вероятности однолетней летальности по причине ОДСН.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>острая декомпенсация сердечной недостаточности</kwd><kwd>биомаркеры</kwd><kwd>прогнозирование</kwd><kwd>кардиовертер-дефибриллятор.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>mortality from cardiovascular events</kwd><kwd>biomarkers</kwd><kwd>prognosis</kwd><kwd>cardioverter-defibrillator.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ФГБОУ ВО Астраханский ГМУ Минздрава России, ФГБУ «Федеральный центр сердечно-сосудистой хирургии» Минздрава России; ФГБУ «НМИЦ Кардиологии» Минздрава России</funding-statement><funding-statement xml:lang="en">.
