Средний возраст составил 58,5±14,7 лет. У всех пациентов выполнено традиционное клинико-лабораторной обследование, ЭХОКГ. Скорригиро-ванную на частоту сокращений желудочков величину интервала QT рассчитывали по формуле Framingham. Пациенты были клинически стабильны, нарушения сердечного ритма и проводимости, требующие медикаментозной коррекции, отсутствовали.</p></sec><sec><title>Результаты</title><p>Результаты. В течение 5 лет наблюдения умерли 23 пациента. Учитывая разное число мужчин и женщин среди обследуемых, показатели смертности рассчитывали отдельно для каждой из гендерных групп. Для мужчин смертность составила 27%, или 6,7 за 100 пациенто-лет (6,7 на 100 человек в год). Для женщин соответственно 36,4%, или 8,5 за 100 пациенто-лет (8,5 на 100 человек в год). Шанс развития ВСС для мужчин составил 0,37, для женщин 0,57. Таким образом, риск ВСС у женщин был в 1,5 раза выше, чем у мужчин. Нормативы для интервала QT предложены для общей популяции. Мы рассчитали: прогностически значимая величина интервала QT в отношении внезапной сердечной смерти у наших пациентов составила 440 мсек и более; площадь под ROC кривой 0,978 (95% ДИ 0,911-0,998), р=0,0001. Чувствительность 95,6%, специфичность 100%. Ряд определяемых показателей в течение пятилетнего срока наблюдения изменился (дельта). Выявлены корреляции между величиной QT и дельтой индекса массы тела Rs=-0,458 p=0,002; дельтой гемоглобина Rs=-0,338 p=0,025; дельтой ширины распределения тромбоцитов по объему Rs=0,377 p=0,011.</p></sec><sec><title>Заключение</title><p>Заключение. Данные нашего исследования позволяют предложить для практического применения изучение в динамике интервала PQ в сопоставлении с динамикой индекса массы тела, уровня гемоглобина и ширины распределения тромбоцитов по объему. Данный подход представляется нам весьма важным в первую очередь у клинически стабильных пациентов при скорригированной на частоту сокращений желудочков величине интервала PQ ≥ 440 мсек.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim: to clarify the safe range of the values of the corrected QT interval and to identify risk factors that contribute to its increase in patients with end-stage renal disease who receive treatment with programmed hemodialysis (HD).</p></sec><sec><title>Patients and methods</title><p>Patients and methods. 70 patients (26 men and 44 women) with end-stage renal disease receiving HD were observed for 5 years. The average age was 58.5 ± 14.7 years. A traditional clinical and laboratory examination, echocardiography was performed in all patients. The value of the QT interval corrected for the frequency of ventricular contractions was calculated using the Framingham formula. The patients were clinically stable, there were no violations of heart rhythm and conduction requiring medical correction.</p></sec><sec><title>Results</title><p>Results. During 5 years of observation, 23 patients died. Given the different number of men and women among the surveyed, mortality rates were calculated separately for each of the gender groups. For men, mortality was 27% or 6.7 per 100 patient-years (6.7 per 100 people per year). For women, respectively, 36.4% or 8.5 per 100 patient-years (8.5 per 100 people per year). The chance of sudden cardiac death for men was 0.37, for women - 0.57. Thus, the risk of sudden cardiac death in women was 1.5 times higher than in men. The guidelines for the QT interval are proposed for the general population. We calculated the prognostic value of the QT interval in relation to sudden cardiac death in our patients was 440 msec or more; the area under the ROC curve is 0.978 (95% CI 0.911-0.998), p = 0.0001. Sensitivity 95.6%, specificity 100%. A number of identifiable indicators during the five-year observation period has changed (delta). There were identified correlations between the value of QT and the delta of body mass index Rs = -0.458 p = 0.002; delta of hemoglobin Rs = -0,338 p = 0.025; delta width of the distribution of platelets by volume Rs = 0.377 p = 0.011.</p></sec><sec><title>Conclusion</title><p>Conclusion. The data of our study allow us to offer for practical application a dynamics study of the PQ interval in comparison with the dynamics of body mass index, hemoglobin level and the width of the distribution of platelets by volume. This approach seems to us very important primarily in clinically stable patients with the PQ ≥ 440 msec interval corrected for the frequency of ventricular contractions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>терминальная почечная недостаточность</kwd><kwd>гемодиализ</kwd><kwd>интервал QT</kwd><kwd>внезапная сердечная смерть</kwd><kwd>ширина распределения тромбоцитов по объему</kwd></kwd-group><kwd-group xml:lang="en"><kwd>end-stage renal disease</kwd><kwd>hemodialysis</kwd><kwd>QT interval</kwd><kwd>sudden cardiac death</kwd><kwd>platelet distribution withdrawal</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">Fox CS, Matsushita K, Woodward M et al.
