Patients received "standard therapy" for CHF in combination with sucrosomial iron (60 mg/day orally) for three months. Treatment response was assessed via clinical blood test, iron metabolism parameters, inflammatory markers, and functional tests at baseline and three months post-treatment.</p></sec><sec><title>   Results</title><p>   Results. Anaemia in CHFpEF corresponds to anaemia of chronic disease with elevated hepcidin content, 219 (149-553) ng/mL occurs with impaired absorption and metabolism of iron and the development of iron deficiency. Hemoglobin levelincreased from 115 (98-117) g/L to 120 (103-133) g/L, p = 0.01, red blood cell count increased from 3.6 (3.5-4.1) × 1012/L to 4 (3.7-5.3) × 1012/L, p = 0.05, and serum ferritin increased from 106 (40-181) μg/L to 117 (83-166) μg/L, p = 0.04. N-terminal natriuretic propeptide (NT-proBNP) level decreased from 374 (330-443) ng/mL to 236 (128-349) ng/mL, p = 0.004. After treatment, exercise tolerance exercise tolerance improved: 6-minute walk test distance increased from 343.1 ± 100 m to 397±73 m (p = 0.01). Quality of life (QoL) level increased and was determined by the clinical status assessment scale (CAS), p = 0.01 and by the Minnesota Health Failure Questionnaire (MHFLQ), p = 0.002.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Adding oral hepcidin- independent iron to standard HFpEF therapy in patients with CHFpEF and anaemia significantly increased hemoglobin and serum ferritin levels, exercise tolerance, and QoL scores while reducing NT-proBNP levels and NYHA functional class after three months.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>   Цель</title><p>   Цель. Охарактеризовать анемию при хронической сердечной недостаточности (ХСН) с сохраненной фракцией выброса левого желудочка (ХСНсФВ) и оценить эффективность применения препарата железа с гепсидин-независимым механизмом всасывания.</p></sec><sec><title>   Материал и методы</title><p>   Материал и методы. В неконтролируемое исследование включили 30 пациентов с ХСНсФВ I-III функционального класса (ФК) по классификации Нью-Йоркской кардиологической ассоциации (NYHA) и анемией. Пациенты получали стандартную терапию ХСН в сочетании с препаратом сукросомального железа по 60 мг/сут. перорально в течение 3 мес. Ответ на терапию оценивали по показателям клинического анализа крови, обмена железа, маркерам воспаления, изменению функциональных тестов исходно и через 3 мес. после начала лечения.</p></sec><sec><title>   Результаты</title><p>   Результаты. Анемия при ХСНсФВ соответствует анемии хронической болезни с повышенным содержанием гепсидина (219 (149-553) нг/мл) протекает с нарушением всасывания и метаболизма железа и развитием дефицита железа. Концентрация гемоглобина на фоне проводимой комплексной терапии увеличилась с 115 (98-117) г/л до 120 (103-133) г/л, p = 0,01, уровень эритроцитов повысился с 3,6 (3,5-4,1) × 1012/л до 4 (3,7-5,3) × 1012/л, p = 0,05, ферритина сыворотки — с 106 (40-181) мкг/л до 117 (83-166) мкг/л, p = 0,04. Выявлено снижение концентрации N-концевого натрийуретического про-пептида (NT-proBNP) с 374 (330-443) нг/мл до 236 (128-349) нг/мл, p = 0,004. После лечения отмечено повышение толерантности к физической нагрузке в виде снижения ФК по тесту 6-минутной ходьбы с 343,1 ± 100 м до 397 ± 73 м, p = 0,01, установлен прирост качества жизни, определяемый по шкале оценки клинического состояния (ШОКС), p = 0,01 и по Миннесотскому опроснику качества жизни у больных ХСН (MHFLQ), p = 0,002.</p></sec><sec><title>   Заключение</title><p>   Заключение. Добавление перорального препарата железа с гепсидин- независимым механизмом действия к "стандартной" схеме лечения у пациентов с ХСНсФВ и анемией приводит к статистически значимому увеличению содержания гемоглобина, ферритина сыворотки, снижению NT-proBNP, повышению толерантности к физической нагрузке через 3 мес. после начала лечения, улучшению показателей качества жизни по ШОКС и MHFLQ в виде снижения баллов, уменьшению ФК ХСН по NYHA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>сохраненная фракция выброса левого&#13;
