Легочная гипертензия (ЛГ) часто осложняет течение идиопатического легочного фиброза (ИЛФ) и ухудшает его прогноз, однако, эхокардиографические признаки ремоделирования правых камер сердца и клинико-функциональные факторы, ассоциированные с уровнем систолического давления в легочной артерии (СДЛА) при ИЛФ, остаются недостаточно изученными.</p></sec><sec><title>Цель</title><p>Цель. Описать эхокардиографические изменения правых отделов сердца у пациентов с идиопатическим легочным фиброзом в зависимости от наличия ЛГ и определить клинико-функциональные факторы, ассоциированные с величиной систолического давления в легочной артерии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включен 121 пациент с ИЛФ. По данным эхокардиографии пациенты разделены на группы без ЛГ (СДЛА &lt; 35 мм рт. ст., n = 35) и с ЛГ (СДЛА ≥ 35 мм рт. ст., n = 86). Оценивались площадь правого предсердия (Sпп), средний диаметр правого желудочка (ПЖ), TAPSE, индекс TAPSE / СДЛА, фракция выброса левого желудочка (ФВ). Проведены корреляционный анализ (Спирмен), однофакторный и многофакторный линейный регрессионный анализ с величиной СДЛА как непрерывной переменной.</p></sec><sec><title>Результаты</title><p>Результаты. В группе ЛГ отмечены большие Sпп (17,0 vs 13,5 см², p &lt; 0,001), больший диаметр ПЖ (4,00 vs 3,75 см, p &lt; 0,001) и более низкий индекс TAPSE / СДЛА (0,438 vs 0,697, p &lt; 0,001) при отсутствии различий в абсолютном TAPSE (p = 0,941). ФВ левого желудочка была незначительно ниже в группе ЛГ (61 vs 62%, p = 0,016), но оставалась в пределах нормы. СДЛА положительно коррелировало с Sпп (r = 0,491, p = 0,019) и уровнем десатурации в 6-минутном тесте ходьбы (6МТХ) (r = 0,355, p &lt; 0,001), отрицательно – с SpO₂ после нагрузки (r = -0,336, p = 0,001). DLCO положительно коррелировала с SpO₂ после нагрузки (r = 0,347, p = 0,001) и отрицательно – с mMRC (r = -0,338, p = 0,001) и десатурацией в 6МТХ (r = -0,270, p = 0,014). Однофакторный линейный регрессионный анализ показал, что с СДЛА ассоциированы сердечно-сосудистые катастрофы (β = 10,8), хроническая сердечная недостаточность (β = 10,9), десатурация в 6МТХ (β = 1,02 на 1%), SpO₂ после нагрузки (β = -0,603), mMRC (β = 4,52), длительная кислородотерапия (ДКТ) (β = 3,74 на год) и ФВ (β = -0,562). В многофакторной линейной регрессии независимыми детерминантами СДЛА остались индекс Чарльсона (β = 2,205 на 1 балл; p = 0,006), уровень десатурации в 6МТХ (β = 1,153 на 1%; p &lt; 0,001) и длительность ДКТ (β = 4,281 за год; p = 0,020).</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ИЛФ ЛГ сопровождается ремоделированием правых отделов сердца (увеличение Sпп, диаметра ПЖ) и снижением правожелудочково-артериального сопряжения (TAPSE / СДЛА) при сохранном TAPSE. Независимыми детерминантами величины СДЛА выступают коморбидность (индекс Чарльсона), уровень десатурации при нагрузке и длительность кислородотерапии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Pulmonary hypertension (PH) frequently complicates the course of idiopathic pulmonary fibrosis (IPF) and worsens its prognosis; however, echocardiographic signs of right heart chamber remodeling and clinical and functional factors associated with systolic pulmonary artery pressure (PASP) level in IPF remain insufficiently studied.</p></sec><sec><title>Aim</title><p>Aim. To characterize echocardiographic changes in the right heart chambers in patients with idiopathic pulmonary fibrosis depending on the presence of pulmonary hypertension and to identify clinical and functional factors associated with the value of systolic pulmonary artery pressure.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 121 patients with IPF. Based on echocardiography, patients were divided into groups without PH (PASP &lt; 35 mmHg, n = 35) and with PH (PASP ≥ 35 mmHg, n = 86). Right atrial area (RA area), mean right ventricular diameter (RV diameter), TAPSE, TAPSE/PASP ratio, and left ventricular ejection fraction (LVEF) were assessed. Spearman correlation analysis, univariate and multivariate linear regression analysis with PASP as a continuous variable were performed.</p></sec><sec><title>Results</title><p>Results. The PH group showed larger RA area (17.0 vs 13.5 cm², p &lt; 0.001), larger RV diameter (4.00 vs 3.75 cm, p &lt; 0.001), and a lower TAPSE/PASP ratio (0.438 vs 0.697, p &lt; 0.001) with no difference in absolute TAPSE (p = 0.941). LVEF was slightly lower in the PH group (61% vs 62%, p = 0.016) but remained within normal limits. PASP correlated positively with RA area (r = 0.491, p = 0.019) and desaturation level during 6MWT (r = 0.355, p &lt; 0.001), and negatively with post-exercise SpO₂ (r = -0.336, p = 0.001). DLCO correlated positively with post-exercise SpO₂ (r = 0.347, p = 0.001) and negatively with mMRC (r = -0.338, p = 0.001) and desaturation (r = -0.270, p = 0.014). Univariate linear regression showed associations of PASP with cardiovascular events (β = 10.8), CHF (β = 10.9), desaturation (β = 1.02 per 1%), post-exercise SpO₂ (β = -0.603), mMRC (β = 4.52), LTOT duration (β = 3.74 per year), and LVEF (β = -0.562). In multivariate linear regression, independent determinants of PASP were the Charlson comorbidity index (β = 2.205 per 1 point; p = 0.006), desaturation level (β = 1.153 per 1%; p &lt; 0.001), and LTOT duration (β = 4.281 per year; p = 0.020).</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients with IPF, pulmonary hypertension is associated with right heart remodeling (enlarged RA area, RV diameter) and reduced right ventricular-pulmonary arterial coupling (decreased TAPSE/PASP ratio) despite preserved TAPSE. Independent determinants of PASP value are comorbidity burden (Charlson index), desaturation during exercise, and long-term oxygen therapy duration.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>идиопатический легочный фиброз</kwd><kwd>легочная гипертензия</kwd><kwd>эхокардиография</kwd><kwd>правожелудочково-артериальное сопряжение</kwd><kwd>десатурация</kwd><kwd>длительная кислородотерапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>idiopathic pulmonary fibrosis</kwd><kwd>pulmonary hypertension</kwd><kwd>echocardiography</kwd><kwd>right ventricular-pulmonary arterial coupling</kwd><kwd>desaturation</kwd><kwd>long-term oxygen therapy</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">Raghu G, Remy-Jardin M, Myers JL, Richeldi L, Ryerson CJ, Lederer DJ et al.
