Изучить частоту и клинико-прогностическое значение изменений фенотипа хронической сердечной недостаточности (ХСН) на основе динамики фракции выброса левого желудочка (ФВ ЛЖ) в течение 3 лет.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное исследование включено 157 пациентов, госпитализированных с острой декомпенсацией сердечной недостаточности (ОДСН). Оценивали результаты исходной ЭхоКГ и повторных исследований через 3, 6, 12, 24 и 36 мес. Пациентов разделили по исходной ФВ ЛЖ на подгруппы: ХСН с низкой ФВ ЛЖ (ХСНнФВ) (&lt;40%), ХСН с умеренно сниженной ФВ ЛЖ (ХСНунФВ) (40-49%) и ХСН с сохраненной ФВ ЛЖ (ХСНсФВ) (≥50%).</p></sec><sec><title>Результаты</title><p>Результаты. Среди пациентов с исходной ХСНнФВ переход в подгруппу ХСНсФВ наблюдался у 14%, в ХСНунФВ у 20%, прирост ФВ ЛЖ &gt;10% отмечен у 31% пациентов. В подгруппе ХСНунФВ у 48% пациентов ФВ ЛЖ нормализовалась, а у 22% снизилась &lt;40%. В подгруппе ХСНсФВ снижение ФВ ЛЖ &lt;40% зафиксировано в 10% случаев. Согласно модели Кокса, переход из подгруппы ХСНнФВ в подгруппу ХСН с улучшенной ФВ ассоциировался с более высокой общей выживаемостью (HR (hazard ratio) 4,57; 95% доверительный интервал (ДИ): 1,039-20,177; p=0,04). Риск летального исхода по сердечно-сосудистой причине у пациентов, перешедших из подгруппы ХСНнФВ в любую другую подгруппу (ХСНунФВ, ХСНсФВ), также был ассоциирован с лучшей выживаемостью (HR 8,852; 95% ДИ: 1,139-68,805, p=0,04). А в подгруппе ХСНсФВ снижение ФВ &lt;40% было ассоциировано с повышением риска смерти от сердечно-сосудистых причин (HR 4,906; 95% ДИ: 1,086-22,153; p=0,039).</p></sec><sec><title>Заключение</title><p>Заключение. Клинически значимое улучшение сократительной функции сердца наблюдается почти у половины пациентов с исходно сниженной ФВ и ассоциировано с лучшим прогнозом. Снижение ФВ ЛЖ в подгруппе ХСНсФВ является предиктором неблагоприятного исхода.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the incidence and clinical prognostic significance of changes in heart failure (HF) phenotype based on left ventricular ejection fraction (LVEF) changes over 3 years.</p></sec><sec><title>Material and methods</title><p>Material and methods. This retrospective study included 157 patients hospitalized with acute decompensated heart failure (ADHF). The results of baseline echocardiography and repeat examinations at 3, 6, 12, 24, and 36 months were assessed. Patients were divided into subgroups based on baseline LVEF as follows: HF with reduced LVEF (HFrEF) (&lt;40%), HF with mildly reduced LVEF (HFmrEF) (40-49%), and HF with preserved LVEF (HFpEF) (≥50%).</p></sec><sec><title>Results</title><p>Results. Among patients with baseline HFrEF, transition to the HFpEF subgroup was observed in 14%, and transition to the HFmrEF in 20%, while an increase in LVEF &gt;10% was noted in 31% of patients. In the HFmrEF subgroup, LVEF normalized in 48% of patients, and decreased to &lt;40% in 22%. In the HFpEF subgroup, a decrease in LVEF &lt;40% was recorded in 10% of cases. According to the Cox model, the transition from the HFrEF subgroup to the HF with improved EF subgroup was associated with higher overall survival (HR (hazard ratio) 4,57; 95% confidence interval (CI): 1,039-20,177; p=0,04). The risk of cardiovascular death in patients who transitioned from the HFrEF subgroup to any other subgroup (HFmrEF, HFpEF) was also associated with improved survival (HR 8,852; 95% CI: 1,139-68,805, p=0,04). In the HFpEF subgroup, a decrease in LVEF &lt;40% was associated with an increased risk of cardiovascular mortality (HR 4,906; 95% CI: 1,08622,153; p=0,039).</p></sec><sec><title>Conclusion</title><p>Conclusion. Clinically significant improvement in cardiac function is observed in almost half of patients with a baseline reduced LVEF and is associated with a better prognosis. A decrease in LVEF in the HFpEF subgroup is a predictor of unfavorable outcome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>острая декомпенсация</kwd><kwd>эхокардиография</kwd><kwd>фракция выброса левого желудочка</kwd><kwd>амбулаторное наблюдение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>acute decompensation</kwd><kwd>echocardiography</kwd><kwd>left ventricular ejection fraction</kwd><kwd>outpatient follow-up</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">нет</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">Galyavich AS, Tereshchenko SN, Uskach TM, et al. 2024 Clinical practice guidelines for Chronic heart failure.
