To estimate metoprolol succinate effect on regulatory and adaptive status (RAS) of patients with сhronic heart failure (CHF) functional class (FC) I and arterial hypertension (HT) I-II stages. Material and methods. 51 patients with CHF FC I and HT I-II stage, (30 men and 21 women aged 52.6±1.4 yeas). Cardio-respiratory synchronism (CRS) test, 6-minute walking test, tread-mill burden test with registration of maximal oxygen consumption, 24-hour blood pressure monitoring, echocardiography and determination of N-terminal pro-brain natriuretic peptide (NT-proBNP) blood level were performed initially and after 6 months of therapy with metoprolol succinate (dose 78.1±5.7 mg/day) in sustained-release presentation. Results. Metoprolol succinate therapy had no significant effect on RAS (there was no unidirectional dynamics of the basic CRS test parameters: a range of synchronization decreased significantly from 8.8±0.4 to 7.2±0.6 сardio-respiratory cycles per minute (in 18%; р&lt;0.05), and duration of CRS development on the minimal boundary from 18.8±2.2 to 14.3±1.2 сardiocycles (in 24%; р&lt;0,05); RAS index considerably did not change), myocardium structure, exercise tolerance and neuro-humoral activity. Metoprolol therapy only moderately improved left ventricle diastolic function. Conclusion. Metoprolol succinate therapy has no significant effect on RAS of patients with CHF FC I and HT I-II stages.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Оценить влияние метопролола сукцината на регуляторно-адаптивный статус (РАС) у пациентов с хронической сердечной недостаточностью (ХСН) I функционального класса (ФК) и артериальной гипертонией (АГ) I-II стадий. Материал и методы. В исследование включен 51 пациент с ХСН I ФК на фоне АГ I-II стадии (30 мужчин и 21 женщина, возраст 52,6±1,4 лет). Исходно и через 6 мес терапии метопролола сукцинатом замедленного высвобождения (средняя суточная доза 78,1±5,7 мг) выполняли пробу сердечно-дыхательного синхронизма (СДС), тест с 6-минутной ходьбой, суточное мониторирование артериального давления, тредмилометрию с оценкой максимального потребления кислорода при нагрузке, эхокардиографию, определяли уровень N-концевого предшественника мозгового натрийуретического гормона (NT-proBNP) плазмы крови. Результаты. Терапия метопролола сукцинатом существенно не повлияла на РАС (отсутствовала однонаправленная динамика основных показателей пробы СДС: достоверно уменьшились диапазон синхронизации с 8,8±0,4 до 7,2±0,6 кардиореспираторных циклов в мин (на 18%; р&lt;0,05) и длительность развития CДC на минимальной границе с 18,8±2,2 до 14,3±1,2 кардиоциклов (на 24%; р&lt;0,05); индекс РАС значительно не изменялся), структурное состояние миокарда, толерантность к физическим нагрузкам и нейро-гуморальную активность, только умеренно улучшала диастолическую функцию левого желудочка. Заключение. Метопролола сукцинат не оказывает значимого влияния на РАС пациентов с ХСН I ФК и АГ I-II стадий.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>метопролола сукцинат</kwd><kwd>сердечно-дыхательный синхронизм</kwd><kwd>регуляторно-адаптивный статус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>сhronic heart failure</kwd><kwd>metoprolol succinate</kwd><kwd>сardio-respiratory synchronism</kwd><kwd>regulatory and adaptive status</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">Beckett N.S., Peters R., Fletcher A.E. et al.
