Кардиопульмональный нагрузочный тест предоставляет значимую диагностическую и прогностическую информацию о состоянии больных с сердечно-сосудистыми и легочными заболеваниями. Существует серьезная проблема, состоящая в том, что выполнение нагрузочного тестирования испытуемым в его завершающей фазе является физически тяжелым упражнением для человека. Присутствует значительный риск возникновения и развития патологических состояний сердечно-сосудистой системы пациента. Одним из решений данной проблемы является разработка методов оценивания биологических параметров пациентов в конце выполнения нагрузочного протокола на основе данных первых этапов теста.</p></sec><sec><title>Цель работы</title><p>Цель работы. Разработка метода нахождения оценки максимальной частоты сердечных сокращений (ЧСС) и пикового потребления кислорода (ПК) у больных с хронической сердечной недостаточностью (ХСН) в конце выполнения кардиореспираторного нагрузочного стресс-теста на основе результатов исследования, полученных на первоначальных ступенях теста.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для проведения исследования использованы 149 обезличенных записей ритмограмм и данных изменения ПК пациентов с ХСН, которые проходили кардиопульмональный нагрузочный тест на велоэргометре с использованием ступенчатого нагрузочного протокола (прирост мощности нагрузки на каждой ступени составлял 10 Вт, длительность ступени нагрузки была равна 1 мин).</p></sec><sec><title>Результаты</title><p>Результаты. На основе анализа полученных данных разработан метод оценки пиковых значений ЧСС и ПК у больных с ХСН.</p></sec><sec><title>Заключение</title><p>Заключение. Относительная ошибка предложенной оценки пикового значения ЧСС в большинстве случаев не превосходила 10 %, что позволяет ее использовать для практических целей. Установлено, что при выполнении 70 % нагрузочного протокола ошибка предложенной оценки пикового ПК в большинстве случаев не превосходит 20 %. Необходимы дополнительные исследования для повышения точности данной оценки с целью использования в медицинских приложениях, направленных на модернизацию методов и аппаратуры для нагрузочного тестирования пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Cardiopulmonary stress test provides significant diagnostic and prognostic information of the condition of patients with cardiovascular and pulmonary diseases. There is a serious problem, that final phase of stress testing is a physically difficult exercise for a person. There is a significant risk of occurrence and development of pathological conditions of the patient's cardiovascular system. One of the solutions is the development of methods for assessing the biological parameters of the patients at the end of a load protocol based on data from the initial stages of the test.</p></sec><sec><title>Aim</title><p>Aim. Development of a method for finding an estimate of the maximum heart rate (HR) and of the peak oxygen consumption (OC) for the patients with chronic heart failure at the end of a cardiorespiratory exercise stress test, based on the results of the study obtained at the first initial stages of the test.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. For the study, 149 anonymized records of rhythmograms and data of changes in the oxygen consumption of the patients with chronic heart failure were used. The patients underwent a cardiopulmonary stress test by a bicycle ergometer using step-by-step load protocol (the load power increase at each stage was 10 W, the duration of the load stage was 1 min)</p></sec><sec><title>Results</title><p>Results. Based on the analysis of the data obtained, a method for assessing the peak values of HR and of PC of the patients with chronic heart failure was developed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The relative error of the proposed estimate of the HR peak in most cases was no more than 10 %, which allows it to be used for practical purposes. It was established that when performing 70 % of the stress protocol, the error of the proposed estimate of the OC peak in most cases did not exceed 20 %. More research is needed to improve the accuracy of the assessment for using in medical applications aimed to the modernization of methods and equipment for stress testing of the patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>система нагрузочного тестирования человека</kwd><kwd>электрокардиосигнал</kwd><kwd>частота сердечных сокращений (ЧСС)</kwd><kwd>анализ выдыхаемого воздуха</kwd><kwd>регрессионный анализ</kwd><kwd>предсказание показателей тестирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>human stress testing system</kwd><kwd>electrocardiogram</kwd><kwd>heart rate (HR)</kwd><kwd>exhaled breath analysis</kwd><kwd>regression analysis</kwd><kwd>test performance prediction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Выражаем благодарность Национальному медицинскому исследовательскому центру им.
