Выявление и изучение характера нарушений дыхания во сне (НДС) в когорте больных с хронической сердечной недостаточностью (ХСН) со сниженной и умеренно сниженной фракцией выброса (ФВ), госпитализированных в стационар, а также уточнение связи между типом НДС, этиологией и степенью тяжести ХСН.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование были включены 117 пациентов с ХСН со сниженной и умеренно сниженной ФВ, госпитализированные в НМИЦ ТПМ с 2019 по 2021гг. Всем пациентам выполнялось физикальное, лабораторное и инструментальное обследование, в т.ч. кардиореспираторное мониторирование сна. Пациенты были разделены на 3 группы в соответствии с типом и тяжестью НДС: без НДС или с легкой степенью НДС, преимущественно с обструктивным апноэ сна (ОАС) и преимущественно с центральным апноэ сна (ЦАС). Между этими группами были сопоставлены тяжесть НДС и клинические данные.</p></sec><sec><title>Результаты</title><p>Результаты. Всего у 5 пациентов (4,27%) не были зарегистрированы какие-либо НДС, у 47 (40,17%) диагностировано ЦАС, а у 65 человек (55,56%) — ОАС разной степени тяжести. Доли пациентов с умеренной и тяжелой формами ЦАС и ОАС отличались незначительно и составили, соответственно, 35,9% (42 пациента) и 44,4% (52 пациента). Среди причин ХСН наибольшую долю во всех трех группах составила ишемическая болезнь сердца (41,88% от общего числа), неишемическая кардиомиопатия (26,5%), аритмогенная кардиомиопатия (15,38%) и другие причины (16,24%) (гипертоническая болезнь, миокардит, пороки сердца). Установлено, что сниженная ФВ &lt;40%, конечный диастолический объем &gt;210 мл и количество желудочковой эктопии (&gt;300 экстрасистол/сут.) были ассоциированы с наличием ЦАС, а индекс массы тела &gt;30 кг/м2 традиционно был ассоциирован с ОАС.</p></sec><sec><title>Заключение</title><p>Заключение. Более чем у половины пациентов с ХСН с низкой и умеренно сниженной ФВ выявляются НДС. Сниженная ФВ левого желудочка и желудочковая эктопическая активность ассоциирована с ЦАС, а увеличение индекса массы тела — с ОАС. Знание факторов риска, ассоциированных с НДС, может улучшить фенотипирование пациентов для индивидуализации терапии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To identify and study the nature of sleep-related breathing disorders (SBDs) in a cohort of hospitalized patients with heart failure (HF) with reduced and mildly reduced ejection fraction (EF), as well as to clarify the relationship between SBD type, etiology and severity of HF.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 117 patients with HF with reduced and mildly reduced ejection fraction hospitalized at the National Medical Research Center for Therapy and Preventive Medicine from 2019 to 2021. All patients underwent clinical and paraclinical examination, including cardiorespiratory sleep study. Patients were divided into three groups according to the type and severity of SBD: no or mild SBD, predominantly with obstructive sleep apnea (OSA) and predominantly with central sleep apnea (CSA). Severity of SBD and clinical data were compared between these groups.</p></sec><sec><title>Results</title><p>Results. A total of 5 patients (4,27%) did not have any SBDs, while 47 (40,17%) were diagnosed with CSA, and 65 (55,56%) — OSA of varying severity. The proportions of patients with moderate and severe CSA and OSA differed insignificantly and amounted to 35,9% (n=42) and 44,4% (n=52), respectively. There were following proportions of diseases related to HF: coronary artery disease (41,88%), nonischemic cardiomyopathy (26,5%), arrhythmogenic cardiomyopathy (15,38%) and other causes (16,24%) (hypertension, myocarditis, heart defects). We found that reduced EF &lt;40%, end-diastolic volume &gt;210 ml, and ventricular ectopy (&gt;300 extrasystoles/day) were associated with CSA, and body mass index &gt;30 kg/m2 was traditionally associated with OSA.</p></sec><sec><title>Conclusion</title><p>Conclusion. More than half of HF patients with reduced and mildly reduced EF have SBDs. Decreased LVEF and ventricular ectopic activity are associated with CSA, while increased body mass index is associated with OSA. Consideration of SBD risk factors may improve patient phenotyping for individualized therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нарушение дыхания во сне</kwd><kwd>обструктивное апноэ сна</kwd><kwd>центральное апноэ сна</kwd><kwd>хроническая сердечная недостаточность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sleep-related breathing disorders</kwd><kwd>obstructive sleep apnea</kwd><kwd>central sleep apnea</kwd><kwd>heart failure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Российское кардиологическое общество (РКО).
