Оценить клиническое значение осмолярности плазмы крови и ее регуляции при острой сердечной недостаточности у больных инфарктом миокарда (ИМ) со стойким подъемом сегмента ST (ИМпST) в условиях различных стратегий реваскуляризации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включались пациенты, госпитализируемые с предварительным диагнозом ИМпST и клинически значимым диспноэ (n=198). Осмолярность плазмы крови определялась при поступлении расчетным методом. Для оценки интенсивности синтеза вазопрессина иммуноферментным методом определялся уровень копептина. В качестве конечной точки исследования использовались внутригоспитальная летальность и ранние осложнения ИМ.</p></sec><sec><title>Результаты</title><p>Результаты. Пациенты в сформированной выборке были сопоставимы по полу, возрасту, основным факторам кардиоваскулярного риска и клиническому фенотипу ИМ, послужившего поводом для госпитализации. Наивысшая частота ранних осложнений ИМ и интрагоспитальная летальность была среди пациентов с исходной гипоосмолярностью плазмы крови (68,6 и 40,4%, соответственно). Сывороточный уровень копептина имел тенденцию к повышению у больных с исходно низкой осмолярностью плазмы (p=0,178). Исходно низкая осмолярность плазмы была ассоциирована с повышением риска летального исхода (отношение шансов 0,465, 95% доверительный интервал: 0,238-0,911, p=0,024), преимущественно за счет подгруппы больных с консервативной стратегией ведения (отношение шансов 0,335, 95% доверительный интервал: 0,140-0,803, p=0,012).</p></sec><sec><title>Заключение</title><p>Заключение. Осмолярность плазмы крови, оцениваемая при поступлении, может быть использована для прогноза внутригоспитальной летальности при острой сердечной недостаточности у больных ИМпST.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the clinical significance of plasma osmolarity and its regulation in acute heart failure in patients with ST-segment elevation myocardial infarction (STEMI) under various revascularization strategies.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included patients hospitalized with a preliminary diagnosis of STEMI and clinically significant dyspnea (n=198). Plasma osmolarity was determined upon admission by estimation. To assess the intensity of vasopressin synthesis, the copeptin level was determined using an enzyme immunoassay. The study endpoints were inhospital mortality and early complications of MI.</p></sec><sec><title>Results</title><p>Results. The patients in the sample were comparable by sex, age, major cardiovascular risk factors and clinical phenotype of MI that served as a reason for hospitalization. The highest rate of MI early complications and inhospital mortality was among patients with initial plasma hypoosmolarity (68,6 and 40,4%, respectively). Serum copeptin levels tended to increase in patients with initially low plasma osmolarity (p=0,178). Low baseline plasma osmolarity was associated with an increased risk of death (odds ratio (OR) 0,465, 95% confidence interval (CI) 0,238; 0,911, p=0,024), mainly due to the subgroup of patients with a conservative management strategy (OR 0,335, 95% CI 0,140; 0,803, p=0,012).</p></sec><sec><title>Conclusion</title><p>Conclusion. Plasma osmolarity assessed upon admission can be used to predict inhospital mortality in patients with acute heart failure and STEMI.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острая сердечная недостаточность</kwd><kwd>инфаркт миокарда с подъемом сегмента ST</kwd><kwd>осмолярность плазмы крови</kwd><kwd>копептин</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute heart failure</kwd><kwd>ST-segment elevation myocardial infarction</kwd><kwd>plasma osmolarity</kwd><kwd>copeptin</kwd><kwd>prognosis</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">Терещенко С.
