В данной статье представлены результаты компьютерной томографии (КТ) органов грудной клетки с применением КТ-денситометрии, используемой в диагностике различных форм легочной гипертензии.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ: Определение диагностической ценности КТ-денситометрии путем сравнительного анализа плотности легочной ткани у пациентов с различными формами легочной гипертензии.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ: В исследование вошли 528 пациентов с диагностированной легочной гипертензией посредством катетеризации правых отделов сердца (КПОС) Национального научного кардиохирургического центра, Республики Казахстан. Все пациенты были разделены на 4 группы, согласно классификации легочной гипертензии Всемирной организации здравоохранения (Руководство ESC/ERS) 2015 г. Первая группа — 254 пациента с легочной гипертензией, обусловленной патологиями левых отделов сердца (ЛГПЛС). Вторая группа — 210 пациентов с легочной артериальной гипертензией (ЛАГ). Третья группа — 49 пациентов с хронической тромбоэмболической легочной гипертензией (ХТЛГ). Четвертая группа — 15 пациентов с легочной гипертензией, обусловленной патологией дыхательной системы (ЛГПДЛС). Средний возраст пациентов составил 52,15±16,75  года. КТ-исследование огранов грудной клетки с  контрастом проводилось на мультиспиральном 64-срезовом компьютерном томографе (Somatom Definition AS, Siemens) с постпроцессинговым определением денситометрических показателей легочной ткани, анализом диаметров легочного ствола и главных ветвей. КТ-исследование проводилось по программе Embolism с внутривенным введением контрастного препарата по показаниям. Статистика: проводилась с использованием пакета программ Statistica 10. Сравнения двух групп по количественным шкалам проводились на основе непараметрического критерия Манна–Уитни и критерия Краскела–Уоллеса. Для описания количественных показателей использовались среднее значение и  стандартное отклонение в  формате «M±S». Корреляционный анализ проводился на основе непараметрической ранговой корреляции по Спирмену.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: У пациентов с тяжелой легочной гипертензией наиболее четко наблюдалась тенденция к формированию фибротических изменений в группе ЛГ, обусловленной патологиями левых отделов сердца (–809,92±26,52), эмфизематозных изменений в группе легочной артериальной гипертензии (–843,27±43,88).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: КТ-денситометрию легких необходимо проводить всем пациентам с подозрением на ЛГ в качестве дополнительного метода исследования. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>INTRODUCTION</title><p>INTRODUCTION: This article presents the results of application of CT densitometry in the computed tomography (CT) of the chest to diagnose various forms of pulmonary hypertension.</p></sec><sec><title>OBJECTIVES</title><p>OBJECTIVES: To determine the diagnostic value of CT densitometry using comparative analysis of lung tissue density in patients with various forms of pulmonary hypertension.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study included 528 patients diagnosed with pulmonary hypertension by means of right heart catheterization (RHC) of the National Research Cardiac Surgery Center, Republic of Kazakhstan. All patients were divided into 4 groups according to the classification of pulmonary hypertension of the World Health Organization (ESC/ERS Guidelines) from 2015. The first group included 254 patients with pulmonary hypertension pulmonary hypertension due to left heart disease (PHLHD). The second group included 210 patients with pulmonary arterial hypertension (PAH). The third group included 49 patients with chronic thromboembolic pulmonary hypertension (CTEPH). The fourth group — 15 patients with pulmonary hypertension due to respiratory disease (PHDRD). The mean age of the patients was 52.15±16.75 years. Contrast-enhanced chest CT imaging performed with a 64-slice multislice computed tomography system (Somatom Definition AS, Siemens) with post-processing to assess the lung tissue densitometric parameters, analyse the diameters of the pulmonary trunk and its main branches. The CT examination was carried in accordance with an «Embolism» protocol with intravenous administration of a contrast agent according to indications. Statistics: analysis was conducted using the Statistica 10 software. To quantitatively compare the two groups nonparametric Mann-Whitney test and the Kruskal-Wallace test were applied. Mean value and standard deviation in the format of «M±S» were used for quantitative parameters. Correlation analysis was carried out using Spearman’s nonparametric rank correlation.</p></sec><sec><title>RESULTS</title><p>RESULTS: In patients with severe pulmonary hypertension a tendency for fibrotic changes was most clearly observed in cases of pulmonary hypertension due to left heart disease (–809.92±26.52), and emphysematous changes in the pulmonary arterial hypertension group (–843.27±43.88).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: CT lung densitometry should be performed in all patients with suspected pulmonary hypertension as an additional method of examination.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>легочная гипертензия</kwd><kwd>компьютерная томография органов грудной клетки</kwd><kwd>хроническая тромбоэмболическая легочная гипертензия</kwd><kwd>легочная артериальная гипертензия</kwd><kwd>КТ-денситометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulmonary hypertension</kwd><kwd>computed tomography of the chest</kwd><kwd>chronic thromboembolic pulmonary hypertension</kwd><kwd>pulmonary arterial hypertension</kwd><kwd>CT densitometry</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">Hoeper M.M., Humbet M., Souza R. et al.
