Критерии включения: документированный диагноз COVID-19‑ассоциированной пневмонии, желание пациента участвовать в наблюдении. Пациенты были обследованы во время госпитализации и на контрольном визите (через 3 мес после выписки). Обработка изображений и кинопетель, в том числе оценка продольной деформации (longitudinal strain, LS) миокарда при помощи метода отслеживания пятна (speckle tracking), осуществлялась в соответствии с действующими рекомендациями. Уравнение [скорость трикуспидальной регургитации / интеграл линейной скорости потока в выводном тракте ПЖ × 10 + 0,16] использовали для определения ЛСС. Пациенты были разделены на группы: 1‑я группа (n=31) – с повышением ЛСС ≥ 1,5 единиц Вуда, 2‑я группа (n=65) – ЛСС &lt;1,5 единиц Вуда.</p><p>Результаты   Исходно между группами не выявлено различий по основным клинико-функциональным характеристикам, включая тяжесть поражения легких по данным компьютерной томографии (32,7±22,1 и 36,5±20,4 % соответственно; р=0,418). Линейные, планиметрические и объемные параметры, по данным эхокардиографии, между группами статистически значимо не различались. В 1‑й группе на контрольном визите эндокардиальная LS свободной стенки ПЖ (right ventricle free wall, RV FW; –19,3 [–17,9; –25,8] %) была статистически значимо ниже (р=0,048), чем во 2‑й группе (–23,4 [–19,8; –27,8] %), а систолическое давление в легочной артерии – ЛА (systolic pulmonary artery pressure, sPAP) по C. Otto (32,0 [26,0; 35,0] мм рт. ст. и 23,0 [20,0; 28,0] мм рт. ст.) – статистически значимо выше, чем во 2‑й группе (р&lt;0,001). По данным логистического регрессионного анализа, только эндокардиальная RV FW LS (отношение шансов – ОШ 0,859; 95 % доверительный интервал – ДИ 0,746–0,989; р=0,034) и sPAP (ОШ 1,248; 95 % ДИ 1,108–1405; р&lt;0,001) показали независимую связь с повышением ЛСС. Согласно корреляционному анализу Спирмена, выявлена связь средней силы между ЛСС и средним давлением в ЛА по G. Mahan (r=0,516; p=0,003), ЛСС и показателем функциональной связи правых отделов сердца с системой ЛА (r=–0,509; p=0,007) в 1‑й группе на контрольном визите.</p><p>Заключение     У лиц, перенесших 3 мес назад COVID-19‑пневмонию, скрытая правожелудочковая систолическая дисфункция, определенная как угнетение эндокардиальной RV FW LS до –19,3 %, ассоциирована с повышением ЛСС ≥1,5 единиц Вуда.</p></abstract><trans-abstract xml:lang="en"><p>Aim      To study the relationship of echocardiographic right ventricular (RV) structural and functional parameters and indexes of pulmonary vascular resistance (PVR) in patients 3 months after COVID-19 pneumonia.</p><p>Material and methods  This cross-sectional, observational study included 96 patients aged 46.7±15.2 years. The inclusion criteria were documented diagnosis of COVID-19-associated pneumonia and patient’s willing to participate in the observation. Patients were examined upon hospitalization and during the control visit (at 3 months after discharge from the hospital). Images and video loops were processed, including the assessment of myocardial longitudinal strain (LS) by speckle tracking, according to the effective guidelines. The equation [tricuspid regurgitation velocity/ time-velocity integral of the RV outflow tract × 10 + 0.16] was used to determine PRV. Patients were divided into group 1 (n=31) with increased PRV ≥1.5 Wood units and group 2 (n=65) with PRV &lt;1.5 Wood units.</p><p>Results At baseline, groups did not differ in main clinical functional characteristics, including severity of lung damage by computed tomography (32.7±22.1 and 36.5±20.4 %, respectively. р=0.418). Echocardiographic linear, planimetric and volumetric parameters did not significantly differ between the groups. In group 1 at the control visit, endocardial LS of the RV free wall (FW) (–19.3 [–17.9; –25.8] %) was significantly lower (р=0.048) than in group 2 (–23.4 [–19.8; –27.8] %), and systolic pulmonary artery pressure (sPAP) according to C. Otto (32.0 [26.0; 35.0] mm Hg and 23.0 [20.0; 28.0] mm Hg) was significantly higher than in group 2 (р&lt;0.001). According to the logistic regression, only endocardial RV FW LS (odds ratio, OR, 0.859; 95 % confidence interval, CI, 0.746–0.989; р=0.034) and sPAP (OR, 1.248; 95 % CI, 1.108–1405; р&lt;0.001) were independently related with the increase in PVR. Spearman correlation analysis detected a moderate relationship between PVR and mean PAP according to G. Mahan (r=0.516; p=0.003) and between PVR and the index of right heart chamber functional coupling with the PA system (r=–0.509; p=0.007) in group 1 at the control visit.</p><p>Conclusion      In patients 3 months after COVID-19 pneumonia, hidden RV systolic dysfunction defined as depressed endocardial RV FW LS to -19.3% is associated with increased PVR ≥1.5 Wood units.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>пневмония</kwd><kwd>легочное сосудистое сопротивление</kwd><kwd>правый желудочек</kwd><kwd>эхокардиография</kwd><kwd>глобальная продольная деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>pneumonia</kwd><kwd>pulmonary vascular resistance</kwd><kwd>right ventricle</kwd><kwd>echocardiography</kwd><kwd>global longitudinal strain</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Конфликт интересов не заявлен.</funding-statement><funding-statement xml:lang="en">No conflict of interest is reported.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dunham-Snary, K.
