Материалы и методы. В исследование включены 159 пациентов с легочной гипертензией. Всем им проведена катетеризация правых отделов сердца с введением вазодилататора (острая фармакологическая проба). В зависимости от ответа на острую фармакологическую пробу пациенты разделены на 3 группы: «ответчики», «истинные неответчики», пациенты «серой зоны». У всех больных изучались исходные клинические параметры, динамика гемодинамических параметров во время пробы, а также размер правого желудочка, площадь правого предсердия, дистанция в тесте 6-минутной ходьбы и время до ухудшения состояния. Результаты. Показан ряд достоверных различий между пациентами «серой зоны» и больными «ответчиками» и «истинными неответчиками» как в клинических, так и гемодинамических параметрах. Также эти пациенты имеют наибольшую длительность времени до ухудшения состояния.</p></abstract><trans-abstract xml:lang="en"><p>Aim - to analyze functional status and hemodynamic changes in patients who demonstrate vasoreactivity but doesn’t reach the criteria of "positive respond" ("grey zone") and to compare this data with "responders" and "true non-responders". Material and methods. We enrolled 159 patients with pulmonary hypertension. Right heart catheterization with acute vasodilator testing was performed in all cases. Depending on hemodynamic respond during acute vasoreactivity testing patients were divided in to three groups: "responders", "true non-responders" and patients in the "grey zone". The following parameters were analyzed in all included patients: basic clinical parameters, hemodynamic changes, right ventricle size, right atrium area, 6-minute walking test distance and time to clinical worsening. Results. In our study it was shown that patients of "grey zone" had several clinical and hemodynamic parameters that differ significantly from patients "responders" and "true non-responders". Patients in the "grey zone" also have the longest time to clinical worsening.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>легочная гипертензия</kwd><kwd>острая фармакологическая проба</kwd></kwd-group><kwd-group xml:lang="en"><kwd>«серая зона»</kwd><kwd>pulmonary hypertension</kwd><kwd>"grey zone"</kwd><kwd>acute vasoreactivity test</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">Galie N, Humbert M, Vachieryc J, Gibbs S et al. 2015 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension.
