Несмотря на высокую распространенность дефицита железа (ДЖ) при сердечной недостаточности с сохраненной фракцией выброса (СНсФВ), недостаточно исследована взаимосвязь показателей статуса железа с наличием заболевания и параметрами диастолической функции (ДФ) и миокардиальной деформации.</p></sec><sec><title>Цель</title><p>Цель: оценить взаимосвязь показателей статуса железа с наличием заболевания и параметрами ДФ и миокардиальной деформации у больных с СНсФВ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. 67 больных с ФВ ≥ 50% (65,8 ± 5,5 года) с помощью диастолического стресс-теста (ДСТ) разделены на 2 группы: 1-я группа (n = 41) – с СНсФВ, 2-я группа (n = 26) – без СНсФВ. Оценены параметры ДФ, деформация резервуарной фазы левого предсердия (ЛП, left atrial reservoir strain, LASr), глобальная продольная деформация (global longitudinal strain, GLS), диастолический резерв при ДСТ, сывороточное железо (Fe), ферритин, коэффициент насыщения трансферрина железом (КНТЖ), гемоглобин (Hb), N-концевой фрагмент натрийуретического пептида (НУП, NT-proBNP), С-реактивный белок (CРБ), креатинин, расчетная скорость клубочковой фильтрации (рСКФ). Проведен непараметрический корреляционный анализ связей показателей статуса железа с параметрами ДФ, LASr, GLS. Для выявления статистически значимых предикторов СНсФВ построены модели логистической регрессии, проведен их ROC-анализ.</p></sec><sec><title>Результаты</title><p>Результаты. В 1-й группе отмечены более высокая частота функционального класса (ФК) II (NYHA), тенденции к преобладанию женщин, ожирения, большие значения пика Е, NT-proBNP, СРБ &gt; 3,0 мг/мл, меньшие значения Е/е΄, LASr, Hb, КНТЖ. При ДСТ установлены межгрупповые различия всех переменных повышения давления заполнения левого желудочка (ЛЖ), в 1-й группе меньшие максимальная нагрузка и частота сердечных сокращений (ЧСС). Анемия выявлена у 6 (9%) больных: 5 (12,2%) vs 1 (3,8%) соответственно, р = 0,238; дефицит железа – у 27 (40,3%): 18 (43,9%) vs 9 (34,6%), р = 0,157. Отмечены статистически значимые корреляционные связи Fe и КНТЖ с максимальной нагрузкой при ДСТ, параметрами ДФ, но не с LASr и GLS. Выявлена новая точка отсечения КНТЖ, равная 29,2% (AUC = 0,699, р = 0,009; чувствительность – 71%, специфичность – 69%), ассоциированная с наличием СНсФВ (ОШ 5,029 95% ДИ 1,575–16,055; p = 0,006).</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов старше 60 лет ДЖ встречается вне зависимости от СНсФВ, что определяет необходимость его скринингового исследования с целью своевременной коррекции. С наличием СНсФВ выявлена ассоциация снижения КНТЖ менее 29,2%: увеличивается шанс иметь одновременно СНсФВ. Отмечены связи Fe и КНТЖ с максимальной нагрузкой, параметрами ДФ, но не с LASr и GLS. Большая частота СРБ &gt; 3,0 мг/мл при СНсФВ подтверждает провоспалительный статус заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Despite the high prevalence of iron deficiency (ID) in heart failure with preserved ejection fraction (HFpEF), relationship between iron status indicators with the presence of the disease and parameters of diastolic function and myocardial strain have been insufficiently studied.</p></sec><sec><title>Aim</title><p>Aim: To evaluate association of iron status indicators with the disease and parameters of diastolic function and myocardial strain in HFpEF patients.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. According to diastolic stress test (DST) 67 patients with EF &gt; 50% (65.8 ± 5.5 years) were divided into 2 groups: Gr.1 with HFpEF (n = 41), Gr.2 without HFpEF (n = 26). Parameters of diastolic function, left atrial reservoir strain (LASr), global longitudinal strain (GLS), diastolic reserve as per DST, serum iron (Fe), ferritin, iron transferrin saturation coefficient (ITSC) , hemoglobin (Hb), N-terminal pro B-type natriuretic peptide (NT-proBNP), C-reactive protein (CRP), creatinine, estimated glomerular filtration rate (eGFR) were assessed. Spearman method was used to study the relationships between iron status indicators and parameters of diastolic function, LASr, GLS; the cut-off point for ITSC was found by ROC analysis; factors associated with HFpEF were assessed via regression analysis.</p></sec><sec><title>Results</title><p>Results. In group 1, FCII (NYHA) was revealed more frequent with trends to greater prevalence in women, obesity, higher values of peak E, NT-proBNP, CRP &gt; 3.0 mg/ml, lower values of E/e΄, LASr, Hb, ITSC. As per DST, differences between groups in all variables related elevation left ventricular filling pressure were registered; supreme load and heart rate were lowest in Gr1. Anemia was detected in 6 (9%) patients: 5 (12.2%) vs 1 (3.8%), respectively, p = 0.238; Iron deficiency in 27(40.3%): 18 (43.9%) vs 9 (34.6%), p = 0.157. Correlations were defined between Fe and ITSC with supreme load with DST and diastolic function parameters, but not with LASr and GLS. New cut-off point for ITSC = 29.2% (AUC = 0.699, p = 0.009; sensitivity = 71%, specificity = 69%) associated with HFpEF risk (OR 5.029 95% CI 1.575–16.055; p = 0.006) was revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion: Regardless of HFpEF, ID prevailed in patients aged over 60 years old, which determined the necessity of its screening study for the purpose of timely correction. Association between ITSC reduction less than 29.2% and the disease presence was found: risk of having HFpEF concurrently increased by five times. Interactions were registered between Fe and ITSC with supreme load and diastolic function parameters, but not with LASr and GLS. Higher incidence of CRP &gt; 3.0 mg/ml with HFpEF confirmed pro-inflammatory status of the disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>дефицит железа</kwd><kwd>деформация резервуарной фазы левого предсердия</kwd><kwd>глобальная продольная деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure with preserved ejection fraction</kwd><kwd>iron deficiency</kwd><kwd>left atrial reservoir strain</kwd><kwd>global longitudinal deformation</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">Savarese G., Becher P.M., Lund L.H., Seferovic P., Rosano G.M.C., Coats A.J.S.
