Оценить критерии дефицита железа (ДЖ), основанные на оценке уровня ферритина, коэффициента насыщения трансферрина железом (КНТЖ), сывороточного железа (СЖ), а также значимость растворимых рецепторов трансферрина (рТФР), рТФР/Log ферритина в диагностике ДЖ при хронической сердечной недостаточности с сохраненной фракцией выброса (ХСНсФВ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Включено 88 пациентов с ХСНсФВ. Анализировали показатели обмена железа в подгруппах в зависимости от уровня ферритина и проводили сопоставление общепринятых критериев ДЖ с критериями, валидированными по костному мозгу и индексом рТФР/Log ферритина.</p></sec><sec><title>Результаты</title><p>Результаты. В группе с ферритином ≤30 мкг/л значимые корреляции установлены с показателями СЖ, КНТЖ, рТФР, рТФР/Log ферритина, а ДЖ определялся по всем исследуемым критериям у большинства пациентов. В группе с ферритином &gt;30 мкг/л значимых взаимосвязей между ним и другими маркерами ДЖ не выявлено (p&gt;0,05), но установлены корреляции рТФР/Log ферритина с СЖ (p=0,042) и КНТЖ (p=0,048). В группе с ферритином 31-100 мкг/л в 68,7% случаев происходило расхождение диагноза ДЖ при сопоставлении критериев. Индекс рТФР/Log ферритина согласовывался с критериями, валидированными по костному мозгу.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ХСНсФВ и ферритином ≤30 мкг/л он имеет самостоятельное диагностическое значение и может служить единственным критерием ДЖ; при значениях ферритина &gt;30 мкг/л требуется оценка дополнительных маркеров — СЖ, КНТЖ, рТФР, рТФР/Log ферритина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate iron deficiency (ID) criteria based on the assessment of ferritin levels, transferrin saturation (TSAT), serum iron (SI), as well as the significance of soluble transferrin receptors (sTfR) and the sTfR/log ferritin index in the diagnosis of ID in patients with heart failure with preserved ejection fraction (HFpEF).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 88 patients with HFpEF. Iron metabolism parameters were analyzed in subgroups depending on ferritin levels. We compared conventional ID criteria with criteria validated by bone marrow examination and the sTfR/log ferritin index.</p></sec><sec><title>Results</title><p>Results. In the group with ferritin ≤30 µg/L, significant correlations were established with SI, TSAT, sTfR, and the sTfR/log ferritin index; ID was confirmed by all studied criteria in the majority of patients. In the group with ferritin &gt;30 µg/L, no significant correlations were found between ferritin and other ID markers (p&gt;0,05), but correlations were established between the sTfR/log ferritin index and SI (p=0,042) and TSAT (p=0,048). In the group with ferritin 31-100 µg/L, a discrepancy in ID diagnosis was observed in 68,7% of cases when comparing different criteria. The sTfR/ log ferritin index showed consistency with bone marrow-validated criteria.</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients with HFpEF and ferritin ≤30 µg/L, ferritin has independent diagnostic value and can serve as the sole criterion for ID; at ferritin levels &gt;30 µg/L, the assessment of additional markers (SI, TSAT, sTfR, TfR/log ferritin index) is required.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>дефицит железа</kwd><kwd>растворимые рецепторы трансферрина</kwd><kwd>рТФР</kwd><kwd>ферритин</kwd><kwd>индекс растворимых рецепторов трансферрина/ферритина</kwd><kwd>рТФР/log ферритина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure with preserved ejection fraction</kwd><kwd>iron deficiency</kwd><kwd>soluble transferrin receptors</kwd><kwd>sTfR</kwd><kwd>ferritin</kwd><kwd>soluble transferrin receptor/ferritin index</kwd><kwd>sTfR/log ferritin</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">Fukuta H, Hagiwara H, Kamiya T.
