Materials and methods: 57 patients with PAH were examined. The diagnosis of PAH was verified according to the recommendations of the ERS/ESC from 2015. All patients underwent a detailed echocardiographic (ECHO) study, MRI of the heart and right heart catheterization (RHC). To calculate the stiffness of the pulmonary artery wall, the MRI and RHC data were used. Results: We identified a correlation between the functional class of PAH and the parameters of hemodynamic, physical performance, ECHO parameters of the right chambers. There were no differences in the stiffness of the pulmonary artery wall, depending on the functional class of PAH. Among the six stiffness indicators, only pulsation index was associated with the structural and functional parameters of the right ventricle and pulmonary vascular resistance. Conclusion: The MRI pulsation index is the simpleststiffness index of the pulmonary artery wall and the most promising one for evaluating the prognosis of patients with PAH.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Охарактеризовать механические свойства стенки легочной артерии (ЛА) у пациентов с легочной артериальной гипертензией (ЛАГ), используя данные магнитно-резонансной томографии (МРТ) сердца, а также определить их диагностическое и прогностическое значение. Материалы и методы. Обследовано 57 пациентов с ЛАГ. Диагноз ЛАГ верифицирован согласно рекомендациям ERS/ESC от 2015 г. Всем пациентам выполнено развернутое эхокардиографическое (ЭхоКГ) исследование, МРТ сердца и катетеризация правых отделов сердца (КПОС). Для расчета показателей жесткости стенки ЛА использовались данные МРТ и КПОС. Результаты. Подтверждена связь между функциональным классом ЛАГ и показателями гемодинамики, физической работоспособности, ЭхоКГ параметрами правых камер. Не установлено различий в показателях жесткости ЛА в зависимости от функционального класса ЛАГ. Среди шести анализируемых показателей жесткости только индекс пульсации сопряжен со структурно-функциональными показателями правого желудочка и легочным сосудистым сопротивлением. Заключение. Индекс пульсации - наиболее простой в исполнении и перспективный в отношении оценки прогноза больных с ЛАГ МРТ показатель жесткости стенки легочной артерии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pulmonary hypertension</kwd><kwd>right ventricular heart failure</kwd><kwd>stiffness of the vessel wall</kwd><kwd>pathophysiology of pulmonary arterial hypertension</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>легочная гипертензия</kwd><kwd>правожелудочковая недостаточность</kwd><kwd>жесткость сосудистой стенки</kwd><kwd>патофизиология легочной артериальной гипертензии</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Казымлы А.В., Рыжков А.В., Симакова М.А., Козленок А.В., Наймушин А.В., Моисеева О.М.
