Хроническая обструктивная болезнь легких (ХОБЛ) и хроническая сердечная недостаточность часто сочетаются в клинической практике и представляют трудности в дифференциальной диагностике. Обострения ХОБЛ могут приводить к ухудшению сердечной деятельности, существенно влияющему на прогноз заболевания.</p></sec><sec><title>Цель</title><p>Цель. Оценить диагностическую значимость показателей сердечной деятельности, полученных методом эхокардиографии, при обострении ХОБЛ и в динамике заболевания.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 128 человек, в том числе 103 пациента с обострением ХОБЛ, составивших 3 группы: группу А (n = 21), группу В (n = 24), группа Е (n = 58) в соответствии с категоризацией GOLD (2023). Контрольную группу составили 25 человек без ХОБЛ. В ходе исследования были установлены следующие контрольные точки: 1-я точка наблюдения – первичное обследование, 2-я точка – через 3-6 месяцев, 3-я точка – через 9-12 месяцев. Диагноз ХОБЛ и степень ограничения объема форсированного выдоха за 1 сек. (ОФВ1) подтверждены результатами спирометрии на аппарате Easy on-PC (ndd Medizintechnik AG, Швейцария) до и после пробы с бронхолитиком. Функцию внешнего дыхания дополнительно оценивали с помощью диффузиометрии. Для клинической характеристики пациентов использовали вопросники CAT и mMRC. Оценку структурно-функционального состояния сердца проводили методом трансторакальной эхокардиографии секторальным датчиком 5 МS c частотой 1,5-4,6 мГц с использованием постоянно-волнового, импульсно-волнового допплеровского режимов, тканевой допплерографии и спекл-трекинг эхокардиографии для оценки глобальной продольной деформации желудочков.</p></sec><sec><title>Результаты</title><p>Результаты. Во всех группах больных ХОБЛ при обострении выявлялись изменения сердечной деятельности, о чем свидетельствовали снижение показателей систолической функции обоих желудочков сердца и признаки диастолической дисфункции, наиболее выраженные в группе Е у пациентов с высоким риском обострений и выраженными клиническими проявлениями заболевания. По данным корреляционного анализа систолическая и диастолическая дисфункции обоих желудочков сердца были связаны со степенью нарушений бронхиальной проходимости, диффузионной способности легких и сопряжены с увеличением уровня NT-proBNP. У больных групп А и В отмечалась частичная коррекция ряда эхокардиографических показателей через 3-6 месяцев после обострения. В группе Е в течение года формировались неблагоприятные тенденции к ухудшению сердечной деятельности.</p></sec><sec><title>Заключение</title><p>Заключение. Обострение ХОБЛ сопровождается изменениями показателей эхокардиографии, отражающими структурно-функциональные нарушения сердца и прекапиллярную легочную гипертензию, наиболее выраженными в группе Е. Эхокардиографический мониторинг обеспечивает полноценный анализ динамики изменений сердечной деятельность у больных ХОБЛ, перенесших обострение заболевания, что имеет большое клиническое значение для прогноза и выработки тактики лечения. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Chronic obstructive pulmonary disease (COPD) and chronic heart failure are often combined in clinical practice and present difficulties in differential diagnosis. COPD exacerbations can lead to deterioration of cardiac function, significantly affecting the prognosis of the disease.</p><p>We aimed to estimate diagnostic significance of cardiac activity indices obtained by echocardiography in COPD exacerbation and in the dynamics of the disease.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 128 people, including 103 patients with COPD exacerbation, who made up 3 groups: group A (n = 21), group B (n = 24), group E (n = 58) in according to GOLD (2023) categorization. The control group consisted of 25 people without COPD. In the course of the study, the following control points were established: 1st follow-up point – primary examination, 2nd point – after 3-6 months, 3rd point – after 9-12 months. The diagnosis of COPD and the degree of FEV1 limitation were confirmed by the results of spirometry on Easy on-PC (ndd Medizintechnik AG, Switzerland) before and after the bronchodilator test. Lung function was additionally assessed by diffusiometry. CAT and mMRC questionnaires were used for clinical characterization of patients. Structural and functional state of the heart was assessed by transthoracic echocardiography with 5 MS sector transducer with the frequency of 1.5-4.6 mHz using constant-wave, pulsed-wave Doppler modes, tissue Doppler and speckle-tracking echocardiography to assess global longitudinal ventricular strain.</p></sec><sec><title>Results</title><p>Results. In all groups of COPD patients at exacerbation the changes of cardiac activity were revealed, as evidenced by the decrease of systolic function indices of both heart ventricles and signs of diastolic dysfunction, the most pronounced in group E in patients with high risk of exacerbations and pronounced clinical manifestations of the disease. According to the correlation analysis, systolic and diastolic dysfunction of both heart ventricles are associated with the degree of airway patency disorders, lung diffusion capacity and associated with an increase in NT-proBNP. In patients of groups A and B partial correction of some echocardiographic parameters in 3-6 months after exacerbation was noted. In group E, unfavorable tendencies to deterioration of cardiac activity are formed within a year.</p></sec><sec><title>Conclusion</title><p>Conclusion. COPD exacerbation is accompanied by changes in echocardiographic parameters reflecting structural and functional heart disorders and precapillary pulmonary hypertension, most pronounced in group E. Echocardiographic monitoring provides a complete analysis of the dynamics of changes in cardiac performance in COPD patients who have undergone exacerbation of the disease, which is of great clinical importance for prognosis and development of treatment tactics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эхокардиография</kwd><kwd>сердечная недостаточность</kwd><kwd>хроническая обструктивная болезнь легких</kwd><kwd>концевой фрагмент прогормона мозгового натрийуретического пептида</kwd><kwd>диастолическая дисфункция</kwd><kwd>фракция выброса</kwd><kwd>легочная гипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>echocardiography</kwd><kwd>heart failure</kwd><kwd>chronic obstructive pulmonary disease</kwd><kwd>terminal fragment of brain natriuretic peptide prohormone</kwd><kwd>diastolic dysfunction</kwd><kwd>ejection fraction</kwd><kwd>pulmonary hypertension</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">Респираторная медицина: руководство: в 4-х т. / под ред.
