Изучение прогностической значимости маркеров канальцевой дисфункции у пациентов с острым коро­нарным синдромом (ОКС) и артериальной гипертензией (АГ) имеет высокую актуальность в связи с единством па­тогенетических механизмов и их последствиями, развивающимися при остром коронарном событии. ЦЕЛЬ. Анализ влияния показателей канальцевой дисфункции на риск развития сердечно-сосудистых осложнений у пациентов с АГ в позднем периоде после ОКС. ПАЦИЕНТЫ И МЕТОДЫ. В исследование включены 103 пациента с АГ и ОКС. Всем включенным в исследование пациентам была выполнена коронароангиография (КАГ) со стентированием коронарных артерий. Перед КАГ осуществлялся сбор клинико-анамнестических данных, применяли лабораторные (в том числе креатинин и мочевина, калий и натрий, осмолярность плазмы) и инструментальные методы диагностики. Определяли концентрацию калия и натрия в суточной моче, калийурез и натрийурез, осмолярность мочи, расчетный показатель осмолярного клиренса (ОК). Была выполнена импедансоспектрометрия для определения водного баланса жидких сред организма. Спустя 17,0±0,51 мес была произведена регистрация конечных точек исследования - ОИМ, НС, ста­бильная стенокардия напряжения, повторная реваскуляризация миокарда (РМ), смерть. РЕЗУЛЬТАТЫ. Установлено, что увеличение ОК ассоциируется с риском развития повторных РМ в позднем периоде после ОКС (х2-критерий = 3,89, р = 0,04). Среди показателей электролитного остатка мочи статистически значимое влияние на риск повторных РМ выявлено при увеличения концентрации калия в моче (х2-критерий = 4,63, р = 0,03) и суточного калийуреза (х2- критерий = 4,85, р = 0,03). Показатель ОК и повышение электролитного остатка мочи были рассмотрены и обоснованы как маркеры канальцевой дисфункции. Установлено комплексное влияние повышения ОК и снижения объема внутри­клеточной жидкости от должных величин (х2-критерий = 6,16, р = 0,4) на риск повторных РМ. Выявлено, что при изме­нении баланса объема общей жидкости и ОК происходит потенцирование риска развития повторных РМ. Показано, что при избыточном введении объема жидкости в организм преимущественно внутривенно и увеличении ОК риск раз­вития повторных РМ существенно возрастает. ЗАКЛЮЧЕНИЕ. Проведенное исследование позволило установить, что наличие канальцевой дисфункции может быть рассмотрено как предиктор неблагоприятного сердечно-сосудистого прогноза у пациентов с ОКС и АГ. Для всестороннего анализа величины риска необходимыми являются контроль го­меостаза и индивидуальный подбор объема внутривенных инфузий.</p></abstract><trans-abstract xml:lang="en"><p>BACKGROUND. The study of the prognostic significance of markers of tubular dysfunction in patients with the acute coronary syndrome (ACS) and arterial hypertension (AH) is highly relevant, due to the unity of pathogenetic mechanisms and their consequences that develop during an acute coronary event. PURPOSE. Analysis of the influence of tubular dysfunction indi­cators on the risk of cardiovascular complications in patients with hypertension in the late period after ACS. PATIENTS ANDMETHODS. The study included 103 patients with hypertension and ACS. All patients included in the study underwent coronary angiography (CAG) with stenting of the coronary arteries. Before CAG, clinical and anamnestic data were collected, labora­tory (including creatinine and urea, potassium and sodium, plasma osmolarity), and instrumental diagnostic methods were used. The concentration of potassium and sodium in the daily urine, potassium and natriuresis, osmolarity of urine, and the calculated osmolar clearance index (ОС) were determined. Impedance spectrometry was performed to determine the water balance of the body's liquid media. After 17.0±0.51 months, the endpoints of the study were registered: AMI, NS, stable stress angina, repeated myocardial revascularization (RM), and death. RESULTS. It was found that an increase in ОС is associated with the risk of developing repeated RM in the late period after ACS (x2-criterion = 3.89, p = 0.04). Among the indicators of the electrolyte balance of urine, a statistically significant effect on the risk of repeated RM was found with an increase in the con­centration of potassium in the urine (x2-criterion = 4.63, p = 0.03) and daily potassium urea (x2-criterion = 4.85, p = 0.03). The ОС index and an increase in the electrolyte balance of urine were considered and justified as markers of tubular dysfunction. The complex effect of increasing the ОС and reducing the volume of intracellular fluid from the proper values (x2-criterion = 6.16, p = 0.4) on the risk of repeated RM was established. It was found that when the balance of the volume of total fluid and CA is changed, the risk of developing repeated RM is potentiated. It is shown that with the excessive introduction of fluid volume into the body, mainly intravenously and an increase in ОС, the risk of developing repeated RM increases significantly. CONCLU­SION. The study revealed that the presence of tubular dysfunction can be considered as a predictor of adverse cardiovascular prognosis in patients with ACS and hypertension. For a comprehensive analysis of the risk value, it is necessary to control homeostasis and individual selection of the volume of intravenous infusions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>канальцевая дисфункция</kwd><kwd>осмолярный клиренс</kwd><kwd>калийурез</kwd><kwd>натрийурез</kwd><kwd>почечные факторы риска</kwd><kwd>острый коронарный синдром</kwd><kwd>артериальная гипертензия</kwd><kwd>реваскуляризация миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tubular dysfunction</kwd><kwd>osmolar clearance</kwd><kwd>kaliuresis</kwd><kwd>natriuresis</kwd><kwd>kidney risk factors</kwd><kwd>acute coronary syndrome</kwd><kwd>arte­rial hypertension</kwd><kwd>myocardial revascularization</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">Gouda М, Ammar AS, NaguibTAetal.
