Сердечная недостаточность (СН) является глобальной проблемой здравоохранения, а развитие острой почечной недостаточностью (ОПН) как осложнения СН увеличивает риск смертности. Целью данного исследования было изучение значимости баланса жидкости для прогнозирования смертности у пациентов с СН, осложненной ОПН. Ретроспективный анализ был проведен с использованием базы данных MIMIC-IV для оценки связи между балансом жидкости и смертностью у пациентов с СН, осложненной ОПН.Материал и методы. Группу исследования составили взрослые пациенты с СН и ОПН, которые были включены в базу данных MIMIC-IV в период с 2008 по 2019 год. Пациенты были разделены на группы выживших и умерших. Первичным показателем результата было количество принятой и выделенной жидкости в течение первых трех дней в отделении интенсивной терапии (ОИТ). Основным результатом была смертность в ОИТ, а вторичным результатом была смертность в течение 28 дней после поступления в ОИТ. Для оценки связи между балансом жидкости и риском смерти использовалась многофакторная модель пропорциональных рисков Кокса после корректировки на потенциальные сопутствующие факторы.Результаты. Всего было включено 1433 пациента. Исследование показало, что по сравнению с группой умерших пациентов в группе выживших - поддерживался более низкий положительный баланс в 1-й день (453,51 мл против 1813,66 мл, соответственно выжившим и умершим пациентам), отрицательный баланс во 2-й день (-246,75 мл против 646,00 мл) и отрицательный баланс в 3-й день (-350,21 мл против 312,92 мл). Кроме того, баланс жидкости в первый день предсказывал уровень смертности в отделении интенсивной терапии (AUC 0,658, p &lt; 0,01), на второй день (AUC 0,654, p &lt; 0,01) и на третий день (AUC 0,634, p &lt; 0,01) данный показатель также предсказывал уровень смертности в отделении интенсивной терапии (AUC 0,634, p &lt; 0,01).Заключение. Положительный баланс жидкости у пациентов с СН и ОПН независимо связан с более высокой внутрибольничной смертностью. Мониторинг и управление балансом жидкости могут предоставить врачам важный инструмент для улучшения результатов лечения пациентов.</p></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Heart failure (HF) is a global health issue, and its complication with acute kidney failure (AKF) increases the risk of mortality. This study aimed to investigate the predictive value of fluid balance for mortality in patients with HF complicated by AKF. A retrospective analysis was performed using the MIMIC-IV database to evaluate the relationship between fluid balance and mortality in patients with HF complicated by AKF.Material and methods. Adult patients with HF and AKF and who were listed in the MIMIC-IV database between 2008 and 2019 were included. The patients were divided into survival and non-survival groups. The primary outcome measure was fluid intake and output in the first three days in the intensive care unit (ICU). The main outcome being in-ICU mortality and the secondary outcome being 28‑day mortality after ICU admission. A multivariable Cox proportional hazards model was used to assess the relationship between fluid balance and the risk of death, after adjusting for potential confounding factors.Results. A total of 1433 eligible patients were included. The study found that compared to the death group, patients in the survival group maintained lower positive balance on day 1 (453.51 ml vs 1813.66 ml), negative balance on day 2 (-246.75 ml vs 646.00 ml), and negative balance on day 3 (-350.21 ml vs 312.92 ml). Additionally, fluid balance on the first day predicted ICU mortality rate (AUC 0.658, p&lt;0.01), on the second day it predicted ICU mortality rate (AUC 0.654, p&lt;0.01), and on the third day it also predicted ICU mortality rate (AUC 0.634, p&lt;0.01).Conclusion. Positive fluid balance in patients with HF and AKF is independently associated with higher in-hospital mortality. Monitoring and managing fluid balance may provide clinicians with an important tool to improve patient outcomes.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Сердечная недостаточность</kwd><kwd>острая почечная недостаточность</kwd><kwd>баланс жидкости</kwd><kwd>уровень смертности</kwd><kwd>модель прогнозирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Heart failure</kwd><kwd>acute kidney failure</kwd><kwd>fluid balance</kwd><kwd>mortality rate</kwd><kwd>prediction model</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Конфликт интересов не заявлен</funding-statement><funding-statement xml:lang="en">No conflict of interest is reported.</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">Berger JH, Shi Y, Matsuura TR, Batmanov K, Chen X, Tam K et al.
