All patients underwent comprehensive clinical and instrumental examination in accordance with the standards for patients with CHF. The VP level was determined using ELISA. Statistical analysis was performed using the IBM SPSS Statistics v. 23 software.</p><p><bold>Results. </bold>The patients with CHF had significantly higher blood VP levels compared to the control group (72.91 ± 53.9 pg/ml versus 6.6 ± 3.2 pg/ml respectively; p &lt;0.01). At the same time, patients with stage III CHF had significantly lower VP levels than patients with stages IIВ and IIА (35.61 ± 21.53 pg/ml versus 71.67 ± 48.31 pg/ml and 86.73 ± 59.78 pg/ml respectively; p&lt;0.01). A similar picture was observed for the functional classes (FC). For instance, for CHF FC II and III, the VP level was 91.93 ± 67.13 pg/ml and 77.95 ± 54.01 pg/ml respectively, while for FC IV it decreased to 50.49 ± 28.18 pg/ml (p &lt;0.01). The VP concentration in patients who subsequently perished was significantly lower than in patients who survived (48.79 ± 26.30 pg/ml versus 79.72 ± 57.73 pg/ml; p = 0.012). Moreover, in patients with LVEF &lt;50 %, the VP level was significantly lower than in patients with LVEF &gt;50 % (59.43 ± 42.51 pg/ml versus 86.43 ± 62.46 pg/ml respectively; p &lt;0.05).</p><p><bold>Conclusion</bold><bold>. </bold>The observed significant differences in VP in patients with stage III and IV CFH can indicate depletion of neurohumoral mediators in this patient category. However, a correlation between the VP level and the level of LVEF decrease can indicate a significant difference in the role of VP in CHF pathogenesis in patients with preserved and decreased LVEF. This observation requires further research.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования </bold>– оценить концентрацию вазопрессина (ВП) у пациентов с различной тяжестью хронической сердечной недостаточности (ХСН), выраженностью клинических симптомов и степенью снижения фракции выброса (ФВ) левого желудочка (ЛЖ).</p><p><bold>Материалы и методы. </bold>Обследовано 120 пациентов (44 мужчины, 76 женщин) с ХСН различного генеза (средний возраст 72,12 ± 10,18 года) и 30 клинически здоровых лиц (18 мужчин, 12 женщин) в качестве контрольной группы (средний возраст 33,4 ± 6,23 года). Все пациенты проходили комплексное клинико-инструментальное обследование в соответствии со стандартами обследования пациентов с ХСН. Уровень ВП определяли методом иммуноферментного анализа. Статистическую обработку данных проводили с использованием статистического пакета IBM SPSS Statistics v. 23.</p><p><bold>Результаты</bold><bold>. </bold>В крови пациентов с ХСН в сравнении со здоровыми представителями контрольной группы отмечали значимо более высокий уровень ВП (72,91 ± 53,9 пг/мл против 6,6 ± 3,2 пг/мл соответственно; p &lt;0,01). В то же время у пациентов с ХСН III стадии уровень ВП был существенно ниже, чем у пациентов с IIБ и IIА стадиями ХСН (35,61± 21,53 пг/мл против 71,67 ± 48,31 пг/мл и 86,73 ± 59,78 пг/мл соответственно; p &lt;0,01). Аналогичную картину наблюдали и для функциональных классов (ФК). Так при II и III ФК ХСН уровень ВП составлял 91,93 ± 67,13 пг/мл и 77,95 ± 54,01 пг/мл соответственно, тогда как при IV ФК он снижался до 50,49 ± 28,18 пг/мл (p &lt;0,01). Концентрация ВП у впоследствии умерших больных была существенно ниже, чем в подгруппе выживших пациентов (48,79 ± 26,30 пг/мл против 79,72 ± 57,73 пг/мл; p = 0,012). Кроме того, среди пациентов с ФВ ЛЖ &lt;50 % содержание ВП было статистически значимо ниже, чем у пациентов с ФВ ЛЖ &gt;50 % (59,43 ± 42,51 пг/мл против 86,43 ± 62,46 пг/мл соответственно; p &lt;0,05).</p><p><bold>Заключение</bold><bold>. </bold>Выявленные существенные различия значений ВП у пациентов с III стадией и IV ФК ХСН могут свидетельствовать об истощении нейрогуморальных медиаторов у данной категории пациентов. Однако наличие взаимосвязи уровня ВП и степени снижения ФВ ЛЖ может быть признаком существенного различия роли ВП в патогенезе ХСН у пациентов с сохраненной и сниженной ФВ ЛЖ, что требует дальнейшего изучения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic heart failure</kwd><kwd>decompensation</kwd><kwd>vasopressin</kwd><kwd>left ventricular ejection fraction</kwd><kwd>functional class</kwd><kwd>terminal stage</kwd><kwd>mortality</kwd><kwd>hospitalization</kwd><kwd>hypervolemia</kwd><kwd>hyponatremia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>декомпенсация</kwd><kwd>вазопрессин</kwd><kwd>фракция выброса левого желудочка</kwd><kwd>функциональный класс</kwd><kwd>терминальная стадия</kwd><kwd>смертность</kwd><kwd>госпитализация</kwd><kwd>гиперволемия</kwd><kwd>гипонатриемия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ziaeiana B., Fonarow G.
