To study the clinical phenotypes of the right ventricular-pulmonary artery coupling (RV-PA coupling) and prognostic features in patients with pulmonary hypertension associated with ischemic chronic heart failure (PH-iCHF).</p></sec><sec><title>Material and methods</title><p>Material and methods. A total of 69 stable patients with PH-iCHF and different left ventricular ejection fractions (LVEF) were examined. PH was defined as an increase in systolic pulmonary artery pressure (sPAP) above 30 mm Hg according to transthoracic echocardiography. The probability of PH was compared to the number of confirmed PH cases. The prevalence of PH-iCHF among CHF patients was established. Correlation between RV-PA coupling and LVEF was assessed. Clinical phenotypes were based on RV-PA coupling values as the tricuspid annular plane systolic excursion (TAPSE) and sPAP ratio. Adverse outcomes such as all-cause mortality and hospitalizations due to CHF decompensation over a follow-up period of 13.2±0.9 months were analyzed.</p></sec><sec><title>Results</title><p>Results. PH-iCHF occurred in 3.3% of CHF cases. sPAP above 30 mm Hg corresponded to 34.8% of patients with high probability of PH. For every 10% increase in LVEF, there was a corresponding increase in RV-PA coupling by 0.096 mm/mmHg. Based on the severity of RV-PA dissociation, three clinical phenotypes were formed: severe (&lt;0.28 mm/mmHg), moderate (≥0.28 and ≤0.47 mm/mmHg) and mild (&gt;0.47 mm/mmHg). Severe RV-PA dissociation was more frequently characterized by significant clinical manifestations (lower limb edema in 53%, ascites in 21% of cases), poor functional state (PH functional class III in 79% of cases), low exercise tolerance (six-minute walk test distance 267.2±107.4 m) and prolonged hospital stays (9.9±4.9 bed-days). High probability of PH was present in 67% of cases with severe RV-PA dissociation. There was no difference in time-to-adverse-outcome across clinical phenotypes. Predictors of adverse prognosis included RV-PA coupling ≤0.47 and ≤0.28 mm/mmHg, sPAP ≥40 mmHg, TAPSE ≤18 mm, right atrial area ≥18 cm², and transverse diameter of right ventricle ≥3.5 cm.</p></sec><sec><title>Conclusion</title><p>Conclusion. The RV-PA coupling provides additional characteristics of clinical and functional status and identifies early adverse outcomes in patients with PH-iCHF.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить клинические фенотипы с учетом правожелудочково-артериального сопряжения (ПЖАС) и прогностические факторы у пациентов с легочной гипертензией, ассоциированной с хронической сердечной недостаточностью ишемического происхождения (ЛГ-иХСН).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 69 больных с ЛГ-иХСН и разными фракциями выброса левого желудочка (ФВ ЛЖ). ЛГ считалось повышение систолического давления в легочной артерии (СДЛА) более 30 мм рт. ст. по данным трансторакальной эхокардиографии. Проводилось сопоставление вероятности ЛГ с количеством подтвержденных случаев. Произведен расчет встречаемости ЛГ-иХСН среди больных с ХСН. Оценена корреляционная связь между ПЖАС и ФВ ЛЖ. Клинические фенотипы формировались на основании значения ПЖАС, как соотношение TAPSE (амплитуда систолического движения кольца трикуспидального клапана) к СДЛА. Проанализированы неблагоприятные исходы в виде смертности от всех причин и госпитализаций в связи с декомпенсацией ХСН за 13,2±0,9 мес. наблюдения.</p></sec><sec><title>Результаты</title><p>Результаты. В 3,3% случаев ХСН встречалась ЛГ-иХСН. Повышению СДЛА &gt;30 мм рт.ст. соответствовало 34,8% больных с высокой вероятностью ЛГ. Увеличение ФВ ЛЖ на 10% соответствовало увеличению ПЖАС на 0,096 мм/мм рт.ст. Сформировано 3 клинических фенотипа с тяжёлым (&lt;0,28 мм/мм рт.ст), умеренным (≥0,28 и ≤0,47 мм/мм рт.ст.) и лёгким (&gt;0,47 мм/мм рт.ст.) разобщением ПЖАС. Тяжелое разобщение ПЖАС чаще характеризовалось выраженными клиническими проявлениями (отеки нижних конечностей 53%, асцит 21% случаев), наихудшим функциональным состоянием больных (функциональный класс ЛГ III в 79% случаев), низкой толерантностью к физической нагрузке (расстояние теста шестиминутной ходьбы 267,2±107,4 м), а также наиболее продолжительным стационарным лечением (9,9±4,9 койко-дней). Тяжелое разобщение ПЖАС в 67% случаев соответствовало высокой вероятности ЛГ. Между клиническими фенотипами отсутствовало различие во времени наступления неблагоприятных исходов. ПЖАС ≤0,47 и ≤0,28 мм/мм рт.ст., СДЛА ≥40 мм рт.ст., TAPSE ≤18 мм, площадь правого предсердия ≥18 см2 и поперечный размер правого желудочка ≥3,5 см являлись предикторами неблагоприятного прогноза при ЛГ-иХСН.</p></sec><sec><title>Заключение</title><p>Заключение. ПЖАС может быть использован как клинико-функциональный предиктор течения заболевания и неблагоприятных исходов у пациентов с ЛГ-иХСН.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>легочная артерия</kwd><kwd>легочная гипертензия</kwd><kwd>правый желудочек</kwd><kwd>правожелудочковая недостаточность</kwd><kwd>сердечная недостаточность</kwd><kwd>правожелудочково-артериальное сопряжение</kwd><kwd>эхокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulmonary artery</kwd><kwd>pulmonary hypertension</kwd><kwd>right ventricle</kwd><kwd>right ventricular dysfunction</kwd><kwd>heart failure</kwd><kwd>right ventricular-pulmonary artery coupling</kwd><kwd>echocardiography</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">Ghio S, Guazzi M, Scardovi AB, et al.; all investigators.
