В исследование включено 60 пациентов с ХСН с систолической дисфункцией левого желудочка (фракция выброса левого желудочка менее 50 %). Проведены стандартные биохимические и гематологические тесты, исследован уровень N-терминального фрагмента мозгового натрийуретического пептида (NT-proBNP) и неспецифических маркеров воспаления (С-реактивный белок (СРБ), фибриноген, лейкоциты, лимфоциты, отношение нейтрофилов к лимфоцитам), выполнены ЭКГ и эхокардиографическое исследование, водородный дыхательный тест с лактулозой для выявления синдрома избыточного бактериального роста в тонкой кишке (СИБР). При наличии жалоб на сердцебиение и перебои в работе сердца или других показаний проводили мониторирование ЭКГ по Холтеру. Группу контроля составили 20 пациентов, сопоставимых с основной группой по полу, возрасту и основным заболеваниям при отсутствии ХСН и СИБР.</p></sec><sec><title>Результаты</title><p>Результаты. Распространенность СИБР среди пациентов с ХСН значительно превышала его распространенность в группе пациентов без ХСН (СИБР выявлен у 25 из 60 пациентов с ХСН (42 %) и у 2 из 22 пациентов без ХСН (9 %); p = 0,0034). Синдром избыточного бактериального роста в тонкой кишке при ХСН не оказывал значимого влияния на функциональный класс, показатели клинического и биохимического анализа крови, данные эхокардиографического исследования, количество наджелудочковых и желудочковых экстрасистол. Однако у пациентов с СИБР отмечались более высокие значения СРБ (медиана и интерквартильный размах: 3,6 (2,5;4,1) vs 2,15 (0,4;5,1); p = 0,041). Кроме того, среди пациентов с ХСН и положительным тестом на СИБР значительно чаще выявлялась желудочковая тахикардия (у 45 % пациентов с СИБР и у 10,71 % пациентов без СИБР; p = 0,01557). Наличие СИБР повышало риски возникновения ЖТ у пациентов с ХСН (ОШ = 6,818, 95 % ДИ: 1,542–30,153; p = 0,011)). Развитие ЖТ у пациентов с СИБР в большей степени было ассоциировано с системным воспалением, чем с тяжестью ХСН, характеризующейся высокими цифрами NT-proBNP, в то время как при отсутствии СИБР отмечено обратное.</p></sec><sec><title>Заключение</title><p>Заключение. Развитие ЖТ у пациентов с СИБР в большей степени ассоциировано с системным воспалением, чем с тяжестью ХСН. СИБР можно рассматривать как дополнительный фактор риска развития системного воспаления и желудочковой тахикардии у пациентов с ХСН. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To identify the relationship between rhythm disturbances, including ventricular tachycardia (VT), and the small intestinal bowel bacterial overgrowth syndrome in chronic heart failure (CHF) with left ventricular systolic dysfunction.</p></sec><sec><title>Materials and methods</title><p> Materials and methods. The study included 60 patients with CHF with systolic dysfunction of the left ventricle (left ventricular ejection fraction less than 50 %). Conventional biochemical and hematological tests , ECG and echocardiography were performed. The level of the N-terminal fragment of the brain natriuretic peptide (NT-proBNP) and nonspecific inflammatory markers (C-reactive protein (CRP), fibrinogen, leukocytes, lymphocytes, neutrophil to lymphocyte ratio) were studied. Lactulose hydrogen breath test was fulfiled to detect the small intestinal bowel bacterial overgrowth syndrome (SIBOS). In the presence of complaints of palpitation and interruptions in the heart work or other indications, Holter ECG monitoring was performed. The control group consisted of 20 patients comparable to the main group by sex, age and major diseases in the absence of CHF and SIBOS.</p></sec><sec><title>Results</title><p>Results. The prevalence of SIBOS among patients with CHF significantly exceeded its prevalence in the group of patients without CHF (SIBOS was detected in 25 of 60 patients with CHF (42 %) and in 2 of 22 patients without CHF (9 %); p = 0.0034). The small bowel bacterial overgrowth syndrome with CHF did not have a significant impact on the functional class and the indicators of clinical and biochemical analysis of blood as well as on echocardiographic data and the number of supraventricular and ventricular extrasystoles. However, in patients with SIBOS, higher CRP values were observed (median and interquartile range: 3.6 (2.5; 4.1) vs 2.15 (0.4; 5.1); p = 0.041). In addition, among patients with CHF and a positive SIBOS test, ventricular tachycardia was significantly more common (in 45 % of patients with SIBOS and in 10.71 % of patients without SIBOS; p = 0.01555). The presence of SIBOS increased the risk of VT in patients with CHF (OR = 6.818, 95 % CI: 1.542 - 30.153; P = 0.011)). The development of VT in patients with SIBOS was associated rather with systemic inflammation than with the severity of CHF characterized by high NTproBNP numbers, while in the absence of SIBOS the opposite trend was noted.</p></sec><sec><title>Conclusion</title><p>Conclusion. The development of VT in patients with SIBOS is associated rather with systemic inflammation rather than with the severity of CHF. SIBOS can be considered as an additional risk factor in the development of systemic inflammation and ventricular tachycardia in patients with CHF. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром избыточного бактериального роста</kwd><kwd>сердечная недостаточность</kwd><kwd>С-реактивный белок</kwd><kwd>нарушения ритма</kwd><kwd>желудочковая тахикардия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>small bowel bacterial overgrowth syndrome</kwd><kwd>heart failure</kwd><kwd>C-reactive protein</kwd><kwd>rhythm disturbances</kwd><kwd>ventricular tachycardia</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">Qin J., Li R., Raes J., Arumugam M., Burgdorf K.
