Functional assessment of external respiration and a 6-minute walk test were performed using Spiropalm 6MWT equipment (Cosmed, Italy). The autonomic status and the influence of the ergoreflex on it were assessed by the method of cardiointervalometry before, during and after the test with external peripheral vascular occlusion using Varicard hardware and software complex (LLC Ramena, Ryazan, Russia).</p> <p><bold><italic>Results.</italic> </bold>When performing a 6-minute walk test, significant differences were obtained between the groups of patients with COPD and of the control group in the majority of the studied parameters (p&lt;0.01). In 18 of 63 patients with COPD, the level of SpO<sub>2</sub> in 6-minute walk test decreased by≥ 4% (p&lt;0.01). The obtained result is of considerable importance for assessment of exercise tolerance in patients with COPD. In tests with external peripheral vascular occlusion in patients with COPD and of the control group, the index of activity of regulatory systems (IARS) increased in both groups. However, after completion of the test, the index in patients with COPD decreased below the initial values (p&lt;0.05), and in patients of the control group the changes were even more pronounced (p&lt;0.01). Patients with COPD were divided into groups depending on the distance covered in 6-minute walk test. Analysis of the data revealed a moderate positive correlation between the covered distance and the forced expiratory volume in the 1st second (FEV<sub>1</sub>, R=0.45, p&lt;0.01).The maximum level of the total effect of the autonomic regulation of blood circulation was recorded in patients who covered the minimum distance (227.77±48.13 m) in 6-minute walk test. Besides, a moderate negative correlation between IARS and the results of 6-minute test was recorded (R=-0.34, p&lt;0.01).</p> <p><bold><italic>Conclusions.</italic> </bold>1. For assessment of the functional status of patients in 6-minute walk test it is important to take measurement of saturation throughout the whole test. 2. The change in IARS values in the test with external peripheral vascular occlusion can be regarded as a reduction of the influence of reflex from the lower limb ergoreceptors on the functional condition of patients. 3. Patients with COPD showed a marked autonomic imbalance. IARS showed a moderate negative correlation with the distance covered in 6-minute walk test. 4. Maximum value of IARS was obtained in patients with the minimal distance covered in 6-minute walk test.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Цель. </italic></bold>Изучить взаимоотношение показателей кардиоинтервалометрии и эргорефлекса с показателями 6-минутного шагового теста у больных хронической обструктивной болезнью легких (ХОБЛ).</p> <p><bold><italic>Материалы и методы. </italic></bold>В исследование включено 63 пациента с ХОБЛ, 40 пациентов – контрольной группы (все – мужчины). Функциональную оценку внешнего дыхания и 6-минутный шаговый тест проводили с использованием оборудования Spiropalm 6 MWT (Cosmed, Италия). Оценку вегетативного статуса и влияние на него эргорефлекса проводили методом регистрации кардиоинтервалометрии до, во время и после пробы с внешней периферической сосудистой окклюзией на оборудовании аппаратно-программного комплекса «Варикард» (ООО «Рамена», Россия).</p> <p><bold><italic>Результаты. </italic></bold>При выполнении 6-минутного шагового теста получены статистически значимые различия между группой пациентов с ХОБЛ и контрольной группой по большинству исследуемых показателей (p&lt;0,01). 18 из 63 пациентов, страдающих ХОБЛ, за время проведения 6-минутного шагового теста, имели снижение уровня SpO<sub>2 </sub>на ≥4% (р&lt;0,01). При проведении пробы с внешней периферической сосудистой окклюзией в обеих группах увеличивался индекс показателей активности регуляторных систем (ПАРС), однако после завершения пробы у больных ХОБЛ показатель уменьшался ниже первоначальных величин (p&lt;0,05), а у контрольной группы изменения оказались еще более выраженными (p&lt;0,01). Пациенты с ХОБЛ были разделены на группы в зависимости от расстояния, пройденного за время теста с 6-минутной ходьбой: выявлена умеренная положительная корреляция между пройденной дистанцией и объемом форсированного выдоха за первую секунду (ОФВ<sub>1</sub>, R=0,45, p&lt;0,01). Максимальный уровень суммарного эффекта вегетативной регуляции кровообращения зарегистрирован у пациентов, преодолевших за время 6-минутного шагового теста минимальное расстояние (227,77±48,13 м). Также зарегистрирована умеренная отрицательная корреляция между индексом ПАРС и результатом теста с 6-минутной ходьбой (R = - 0,34, p&lt;0,01).</p> <p><bold><italic>Выводы. </italic></bold>1. При проведении теста с 6-минутной ходьбой важное значение для оценки функционального статуса пациентов имеет исследование сатурации на протяжении всего теста. 2. Изменение значений индекса ПАРС при проведении пробы с внешней периферической сосудистой окклюзией можно расценивать как снижение влияния рефлекса с эргорецепторов нижних конечностей на функциональное состояние пациентов. 3. У пациентов с ХОБЛ выявлен выраженный вегетативный дисбаланс. Индекс ПАРС имеет умеренную отрицательную корреляцию с пройденным расстоянием при тесте с 6-минутной ходьбой. 4. Максимальные значения индекса ПАРС получены у пациентов с минимально пройденным расстоянием при выполнении теста с 6-минутной ходьбой.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COPD</kwd><kwd>6-minute walk test</kwd><kwd>ergoreflex</kwd><kwd>heart rate variability</kwd><kwd>test with external peripheral vascular occlusion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ХОБЛ</kwd><kwd>6-минутный шаговый тест</kwd><kwd>эргорефлекс</kwd><kwd>вариабельность ритма сердца</kwd><kwd>проба с внешней периферической сосудистой окклюзией</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Troosters T, Molen T, Polkey M, et al.
