Проведен ретроспективный анализ функционального состояния кардиореспираторной системы 10 умерших больных с ИЛФ (5 женщин и 5 мужчин, средний возраст 63,1 ± 9,2 лет). Прижизненно всем больным были проведены бодиплетизмография и исследование диффузионной способности легких, газовый анализ артериальной крови и допплерэхокардиографическое исследование с определением максимального систолического давления в легочной артерии (СДЛА). В гистологических срезах аутопсийного материала проводили морфометрическое исследование легочных артерий (ЛА) и сердца. Выявлены выраженные рестриктивные нарушения, значительное снижение диффузионной емкости легких с альвеолярнокапиллярным блоком, артериальная гипоксемия. СДЛА в среднем составило 44,9 ± 17,4 мм рт. ст. Микроскопические изменения легочной ткани соответствовали обычной интерстициальной пневмонии. Диаметр просвета сосудов у больных ИЛФ был в 1,5 раза меньше, а площадь в 1,7 раза меньше, чем в группе сравнения. Толщина стенки ветвей ЛА при ИЛФ превышала таковую в группе сравнения в 2,9 раза, при этом доля площади мышечного слоя в 2,2 раза была больше, а доля площади интимы в 4,1 раз больше, чем в группе сравнения. Выявлена корреляция между СДЛА и площадью поперечного сечения мелких ветвей ЛА (r = -0,71, p &lt; 0,05), СДЛА и долей интимы в структуре стенки сосуда (r = 0,68, p &lt; 0,05). Диаметр просвета мелких ветвей ЛА коррелировал с длиной правого предсердия (r = –0,81, p &lt; 0,05); масса правого желудочка коррелировала с диаметром (r = –0,71, p &lt; 0,05) и площадью поперечного сечения мелких ветвей ЛА (r = –0,75, p &lt; 0,05). Также выявлены достоверные корреляционные связи между параметрами функции внешнего дыхания, диффузионной способностью легких, функциональными признаками ЛГ. Таким образом, вторичная ЛГ при ИЛФ характеризуется перестройкой сосудистой стенки ветвей ЛА, преимущественно интимы. Уменьшение диаметра просвета сосудов в 1,5 раза является причиной умеренного повышения СДЛА и вызывает развитие легочного сердца.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to investigate functional status of cardiorespiratory system and post-mortem morphometric characteristics of the heart and the lung arteries in secondary pulmonary hypertension (PH) associated with idiopathic pulmonary fibrosis (IPF). A retrospective analysis of functional status of cardiorespiratory system in 10 died patients with IPF (5 males and 5 females, the average age, 63.1 ± 9.2 yrs) was performed. During the last 6 months of their life, all the patients were investigated using body plethysmography, lung diffusing capacity test, arterial blood gas analysis and Doppler echocardiography measuring maximal systolic pulmonary artery (PA) pressure (sysPAP). We also performed histological examination of autopsy samples and morphometric examination of the PA and the heart. Severe restrictive disorders, significant decrease in the lung diffusing capacity with alveolo-capillary block and arterial hypoxemia have been found. The sysPAP was 44.9 ± 17.4 mm Hg in average. Microscopic lung tissue disorders were characteristic for usual interstitial pneumonia. Diameter of the pulmonary vessel lumen in IPF patients was 1.5-fold less and the vessel area was 1.7-fold less than those in controls. In IPF patients, the PA branch wall was 2.9-fold thicker, the proportion of the muscle area was 2.2-fold more and that of the intima area was 4.1-fold more than those in controls. Correlations were found between sysPAP and the cross-sectional area f the PA small branches (r = 0.71; p &lt; 0.05), sysPAP and the proportion of intima area (r = 0.68, p &lt; 0.05). Lumen diameter of the PA small branches correlated with the right atrium length (r = –0.81; p &lt; 0.05) and the right ventricle mass correlated with diameter (r = –0.71; p &lt; 0.05) and the cross-sectional area of the PA small branches (r = –0.75; p &lt; 0.05). Significant correlations were also found between lung function, lung diffusing capacity and function signs of PH. Therefore, secondary PH in IPF is characterized by wall remodeling in the PA branches, mainly due to changes of intima. The 1.5-fold reduction of the vessel lumen is thought to be a cause of moderate growth of sysPAP followed by occurrence of cor pulmonale.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Costabel U., King T.E.
