Всем пациентам были выполнены эхокардиография с верификацией дисфункции: систолическая функция оценивалась по фракции выброса левого желудочка (ФВ ЛЖ) по методу Simpson, для оценки диастолической дисфункции производилось определение скоростных характеристик трансмитрального кровотока и тканевой визуализации движения фиброзного кольца митрального клапана; суточное мониторирование ЭКГ, объемная сфигмоплетизмография периферических артерий, оценка почечной функции с использованием формулы Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) по креатинину и цистатину С, оценка статуса коллагенообразования по уровню тканевого ингибитора матриксных металлопротеиназ 1 типа (TIMP-1) определение N-терминального фрагмента мозгового натрийуретического гормона (NT-proBNP). В первой части исследования пациенты были разделены на три группы — по уровню СКФ &lt;30 мл/мин/1,73 м2, 30-60 мл/мин/1,73 м2 и &gt;60 мл/мин/1,73 м2. Во второй — по уровню цистатина С ниже и выше референсного значения.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлены обратная средней силы взаимосвязь между среднесуточной ЧСС в диапазоне &gt;110 уд./мин и SDNN (r=-0,64, p=0,040) и в диапазоне &lt;70 уд./мин и SDNN (r=0,50, p=0,042); прямая средней силы взаимосвязь уровня цистатина С и среднесуточной ЧСС в диапазоне &gt;70 уд./мин (r=0,44, p=0,022); обратная средней силы взаимосвязь между СКФ по формуле CKDEPIcys и среднесуточной ЧСС в диапазоне &gt;110 уд./мин (r=-0,55, p=0,030). Корреляционный анализ также показал, что у больных постоянной формой ФП и ХСН ишемической этиологии среднесуточная ЧСС имеет прямые сильной степени зависимости взаимосвязи с E/e’ (r=0,53, р=0,011) и с NT-proBNP (r=0,57, р=0,002). Также выявлены обратные высокой степени взаимосвязи SDNN со среднесуточной ЧСС (r=-0,59, p=0,001), с NT-proBNP (r=-0,65, p=0,002), с ФВ ЛЖ (r=-0,50, p=0,019), с соотношением E/e’ (r=-0,61, p&lt;0,001), с TIMP-1 (r=-0,53, p=0,048), средней степени — с ИММЛЖ (r=-0,41, p=0,026) и концентрацией цистатина С (r=-0,38, p=0,036).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Evaluation of structural and functional condition of the left ventricle (LV) and kidneys in permanent atrial fibrillation patients (AF) with ischemic chronic heart failure (CHF) according to mean 24 hour heart rate and heart rate variability.</p></sec><sec><title>Material and methods</title><p>Material and methods. Sixty patients, age 35-60 y. o., with permanent AF of ischemic origin. All patients underwent echocardiography for the dysfunction verification: systolic function was assessed by ejection fraction of the left ventricle by Simpson, diastolic function was assessed via the velocity of transmitral currents and visualization of tissues of the mitral valve; Holter ECG monitoring was done, as volumetric sphygmopletysmography of peripheral arteries, assessment of kidney function by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) by creatinine and cystatin C, evaluation of the status of collagen production by the tissue inhibitor of matrix metalloproteases type 1 (TIMP-1), measurement of NT-proBNP. In the first part of the study, patients were selected to 3 groups: by GFR &lt;30 mL/min/1,73 m2, 30-60 mL/min/1,73 m2 and &gt;60 mL/min/1,73 m2. In the second — by cystatin C levels below or higher than the referent.</p></sec><sec><title>Results</title><p>Results. There is negative moderate correlation of the heart rate &gt;110 bpm and SDNN (r=-0,64, p=0,040) and &lt;70 bpm and SDNN (r=0,50, p=0,042); direct moderate correlation of cystatin C and mean 24 hour heart rate &gt;70 bpm (r=0,44, p=0,022); negative moderate correlation of GFR by CKD-EPIcys and mean daily heart rate &gt;110 bpm (r=-0,55, p=0,030). Correlational analysis also showed that in permanent AF and ischemic CHF the mean 24 hour heart rate correlates strongly with E/e’ (r=0,53, р=0,011) and with NT-proBNP (r=0,57, р=0,002). Also the negative strong correlation found for SDNN with mean 24 hour heart rate (r=-0,59, p=0,001), with NT-proBNP (r=-0,65, p=0,002), with EF LV (r=-0,50, p=0,019), with the relation E/e’ (r=-0,61, p&lt;0,001), with TIMP-1 (r=-0,53, p=0,048), moderate — with the LV myocardial mass index (r=-0,41, p=0,026) and cystatin С concentration (r=-0,38, p=0,036).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>вариабельность сердечного ритма</kwd><kwd>SDNN</kwd><kwd>хроническая сердечная недостаточность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>heart rate variability</kwd><kwd>SDNN</kwd><kwd>chronic 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">Atrial fibrillation 2016 (Management of).
