To study the prognostic significance of cardiobiomarkers - NT-proBNP and soluble suppression of tumorigenecity (sST2) in patients with CHF with preserved (CHFpEF) and mildly reduced EF (CHFmrEF).</p></sec><sec><title>Material and methods</title><p>Material and methods. Along with a clinical examination, 207 patients (111 men and 96 women), mean age - 72.6 ± 11.4 years, underwent tests for the level of NT-proBNP and sST2 in serum. All patients were divided into 3 groups: 1 - CHFpEF (n=85), 2 - CHFmrEF (n=50); 3 (comparison group)- CHFrEF (n=72). All patients signed informed consent to participate in the study. The primary endpoint was all-cause death in 12 months. Statistical processing of the results was carried out using the Statistica 12.0 and Medcalc programs.</p></sec><sec><title>Results</title><p>Results. The initial values ​of NT-proBNP in patients with CHFmrEF were 691.9 [248; 1915.5] pg/ml and were significantly higher than those of CHFpEF - 445.8 [214.6; 945.7] pg/ml, but significantly lower than in CHFrEF - 1131.4 [411.5;3039.5] pg/ml, p&lt;0.05. sST2 values ​​in group 1 (23.21 [12.17;48.7] ng/ml and group 2 (27.11 [16.98;53.76] ng/ml) did not differ, but were significantly lower than in patients with CHFrEF (44.6 [21.1; 93.5] ng/ml). After a median of 12 months 51 patients reached the primary endpoint.  All-causes mortality in patients with HFpEF was 11.8%, HFmrEF - 31.9% (p &lt;0.05), and HFrEF – 36%. A retrospective analysis of the data showed that in patients independent of their initial ejection fraction, who survived for 12 months, the levels of NT-proBNP and sST2 were significantly lower than those of the deceased.  In survivors and deceased patients with CHFpEF the values ​​of NT-proBNP and sST2 were 443 [154;862,8] vs 1143,2 [223,9;2021,9] pg/ml (p=0.009) and 22,8 [12,3;33,8]  vs 26,8 [9,6;74,8] ng/mL (p&lt;0.05). In survivors and deceased patients with CHFmrEF the values ​​of NT-proBNP and sST2 were 397.4 [128.9;1088.5] vs 1939.7 [441.9;2536] pg/ml (p=0.009) and 18.6 [14.9;30.27.1] vs 59.9 [53.76;84.4] ng/mL (p=0.002). There were no significant differences in NT-proBNP and sST2 values ​​in patients with cardiac and non-cardiac causes of death. sST2 parameters in deceased patients with CHFpEF (26.8 [9.6;74.8] ng/mL) and CHFmrEF (59.9 [53.76;84.4] ng/mL) also had no significant differences (p &gt;0.05). At ROC analysis to one-year adverse events, both NT-proBNP and sST2 showed a significant predictive value in patients with EF &gt;40% with an optimal cut-off value of 746 pg/ml (AUC 0.709; p = 0.005, sensitivity 62%, specificity 69%) and 27.1 ng/ml (AUC 0.742; p = 0.03, sensitivity 80%, specificity 75.8%) respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion: NT-proBNP levels &gt;746 pg/ml and sST2 &gt;27.1 ng/ml should be considered as predictors of poor prognosis in CHF patients with LVEF &gt;40%.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить прогностическую значимость кардиобиомаркеров - NT-proBNP и cтимулирующего фактора роста, экспрессируемого геном 2, (ST2) у больных ХСН с сохраненной (ХСНсФВ) и умеренно сниженной фракцией выброса (ХСНунФВ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 207 пациентов c ХСН II-IV ФК NYHA (111 мужчин и 96 женщин), средний возраст – 72,6±11, 4 лет. По данным Эхокг пациенты были разделены на 3 группы: 1 - ХСНсФВ (n=85), 2 - ХСНунФВ (n=50); 3 (группа сравнения) – ХСНнФВ (n=72). Всем больным, подписавшим информированное согласие, наряду со стандартным обследованием, проводилось количественное определение уровня сывороточных биомаркеров (NT-proBNP и sST2) методом ИФА. Оценка выживаемости проводилась через 12 месяцев после включения пациента в исследование. Статистическая обработка результатов проводилась программами Statistica 12.0 и Medcalc.</p></sec><sec><title>Результаты</title><p>Результаты. Исходные значения уровня NT-proBNP у пациентов ХСНунФВ составили 691,9 [248; 1915,5] пг/мл и были значимо выше, чем у ХСНсФВ - 445,8 [214,6; 945,7] пг/мл, но значимо ниже, чем при ХСНнФВ - 1131,4 [411,5;3039,5] пг/мл, р&lt;0,05. Показатели sST2 в группе 1 ( 23,21 [12,17;48,7] нг/мл и группе 2 (27,11 [16,98;53,76] нг/мл) не отличались, но были значимо ниже, чем у больных ХСНнФВ (44,6 [21,1;93,5] нг/мл). В течение 12 месяцев первичной конечной точки достиг 51 пациент. Смертность от всех причин у больных с ХСНсФВ составила 11,8%, при ХСНунФВ - 31,9% (p &lt;0,05), а ХСНнФВ – 36%. У выживших в течение 12 месяцев пациентов, независимо от исходной ФВ ЛЖ, уровни NT-proBNP и sST2 были значимо ниже, чем умерших. У выживших пациентов с ХСНсФВ, показатели NT-proBNP (443 [154;862,8] пг/мл) и sST2 (22,8 [12,3;33,8] нг/мл) были ниже, чем у умерших (1143,2 [223,9;2021,9] пг/мл, p &lt;0,05) и 26,8 [9,6;74,8] нг/мл, p&gt;0,05). У больных ХСНунФВ значения NT-proBNP и sST2 среди выживших и умерших составили 397,4 [128,9;1088,5] vs 1939,7 [441,9;2536] пг/мл (р=0,009) и 18,6 [14,9;30,27,1] vs 59,9 [53,76;84,4] нг/мл (р=0,002) сооветственно. Значимых различий величин NT-proBNP и sST2 у больных с кардиальными и некардиальными причинами смерти выявлено не было. Показатели sST2 у умерших пациентов с ХСНсФВ (26,8 [9,6;74,8] нг/мл) и ХСНунФВ (59,9 [53,76;84,4] нг/мл) также не имели значимых отличий (р&gt;0,05). По данным ROC-анализа у пациентов с ХСН ФВ ЛЖ &gt;40% уровень NT-proBNP &gt; 746 пг/мл (AUG 0,709; p = 0,005) с чувствительностью 62% и специфичностью 69% и уровень sST2 &gt; 27,1 нг/мл (AUG 0,742; p = 0,03) с чувствительностью 80% и специфичностью 75,8% являются предикторами неблагоприятного прогноза.</p></sec><sec><title>Заключение</title><p>Заключение. Уровни NT-proBNP&gt;746 пг/мл и sST2&gt;27,1 нг/мл следует рассматривать как предикторы неблагоприятного прогноза у пациентов ХСН с ФВ ЛЖ &gt;40%.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>sST2</kwd><kwd>хроническая сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>хроническая сердечная недостаточность с умеренно сниженной фракцией выброса</kwd><kwd>отдаленная выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sST2</kwd><kwd>heart failure with preserved ejection fraction</kwd><kwd>heart failure with mildly reduced ejection fraction</kwd><kwd>long-term survival</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке Первого МГМУ им.
