В последние годы оценка скорости пульсовой волны (СПВ) рекомендуется как дополнительный критерий оценки сердечно-сосудистого риска у разных категорий пациентов. Широкое распространение получают такие методы однократной оценки СПВ, как аппланационная тонометрия, многоканальная сфигмография, ультразвуковые методы. Мы поставили цель оценить эффективность анализа СПВ при его 24-часовом мониторировании при обследовании пациентов до и после трансплантации почки с использованием одноканальной сфигмографии. Материал и методы исследования. Обследован 41 пациент, ожидающий трансплантацию почки, в возрасте от 18 до 55 лет, с терминальной хронической почечной недостаточностью на фоне гломерунефрита. Все измерения проводились до трансплантации почки и через 1 и 20 недель после трансплантации. Для оценки 24-часовой СПВ с помощью программы «Vasotens» (ООО «Петр Телегин», Россия) рассчитывали индекс времени нормальной скорости пульсовой волны (Pulse Time Index of Norm, PTIN), определяемый как процент от 24-часового периода, в течение которого СПВ не превышает 10 м/с. Результаты исследования. До трансплантации почки средний PTIN в целом по группе был 56,3±18,4. Затем, через неделю после трансплантации почки, параллельно с посттрансплантационной гипертензией, наблюдалось снижение PTIN у большинства пациентов - 27,6±11,1. После 20 недель средний PTIN в целом по группе вновь увеличился до 52,0±23,6. В нашем исследовании мы обнаружили, что сохранение патологических изменений артериальной жесткости после трансплантации почки является относительно предсказуемым. Мы определили пороговое значение, которое может предсказать одно из двух состояний PTIN, состояние улучшения или состояние ухудшения и без динамики. Пороговое значение PTIN на уровне 45 % имело чувствительность 69 %, специфичность 76 % и AUC 0,65. Анализ ANOVA показал, что в группе с начальным PTIN &gt; 45 %, в отдаленном периоде после трансплантации этот индекс достоверно изменился (р &lt; 0,05), тогда как в группе с начальным PTIN &lt; 45 %, не было никаких существенных изменений. Вывод. Таким образом, 24-часовое мониторирование СПВ и расчет PTIN при ведении пациентов с трансплантацей почки можно рекомендовать в клиническую практику.</p></abstract><trans-abstract xml:lang="en"><p>Background. In recent years, pulse wave velocity (PWV) is recommended as additional test for the evaluation of cardiovascular risk in various patients. The most widely employed methods for evaluating pulse waveforms are those based on applanation tonometry; multi-channel pletysmography, sonography etc. The aim of our study was to assess the feasibility of using an approach to 24-hour pulse wave velocity (PWV) analysis with single-channel sphygmography in the management of patients with renal transplantation. Methods. Overall, 41 patients aged between 18 and 55 years who had end-stage renal disease resulting from glomerulopathy were recruited from the kidney transplant waiting list. All the measurements were performed before kidney transplantation and at 1 and 20 weeks after transplantation. The Pulse Time Index of Norm (PTIN) was calculated with the Vasotens technology for the estimation of the 24-hour PWV, defined as the percentage of the 24-hour period during which the PWV does not exceed 10 m/second. Results. Before kidney transplantation, the mean PTIN in the whole group was 56.3 (standard deviation, 18.4). Then, a week after the renal transplantation, a blood pressure increase and a decrease in the PTIN were observed in most cases, going to 27.6 (standard deviation, 11.1). After 20 weeks, the mean PTIN in the whole group increased again to 52.0 (standard deviation, 23.6). In our study, we found that the persistence of arterial stiffness disturbances after kidney transplantation appears to be relatively predictable. We determined the cutoff value of PTIN that could predict the two states of PTIN: a state of improvement or a state of decline/without change. The cutoff value of PTIN at 45 % had a sensitivity of 69 %, specificity of 76 %, and area under the curve of 0.65. The analysis of variance showed that in the group with an initial PTIN of 45 % or higher, the PTIN in the remote period after transplantation changed significantly (P &lt; 0.05), whereas in the group with an initial PTIN lower than 45 %, there were no significant changes. Conclusion. Thus, the analysis of 24-hour pulse wave velocity in the management of patients with renal transplantation using PTIN is feasible in clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трансплантация почки</kwd><kwd>скорость пульсовой волны</kwd><kwd>24-часовое мониторирование</kwd><kwd>PTIN</kwd><kwd>renal transplantation</kwd><kwd>pulse wave velocity</kwd><kwd>24-hour monitoring</kwd><kwd>PTIN</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">Ageenkova O.
