Определить пороговый уровень натрийуретического пептида для оптимизации диагностики сердечной недостаточности у коморбидных больных с тиреотоксикозом, оценить динамику показателя на фоне терапии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. 111 пациентов в возрасте 58,3±5,6 лет, распределены в 4 группы: основная – 25 пациентов с ишемической болезнью сердца (ИБС), хронической сердечной недостаточностью (ХСН) и тиреотоксикозом; 1-я группа сравнения - 30 пациентов с ИБС и ХСН, без тиреотоксикоза; 2-я группа – 30 пациентов с тиреотоксикозом без ИБС, 3-я группа - 26 пациента с тиреотоксикозом и ИБС, без признаков ХСН. Оценивали функцию щитовидной железы, уровень NT-proBNP исходно и через 6 месяцев лечения тиреотоксикоза, ИБС и ХСН. С помощью ROC-анализа рассчитали пороговый уровень NT-proBNP для диагностики ХСН у коморбидных пациентов.</p></sec><sec><title>Результаты</title><p>Результаты. У пациентов всех групп определялась повышенная концентрация NT-proBNP (более 125 пг/мл), во 2-й группе составила - 225,5 (180,1; 376,1) пг/мл. Значения NT-proBNP у пациентов 1-й и 3-й групп достоверно не отличались. Наиболее высокий уровень NT-proBNP определялся в основной группе - 712,1 (434,3; 893,9) пг/мл. Рассчитали cut-off маркера для скрининга ХСН у пациентов с ИБС и тиреотоксикозом - 556,4 пг/мл (чувствительность - 72%, специфичность - 100%, точность - 87,2% (р&lt;0,001)). Через 6 месяцев лечения уровень NT-proBNP во 2-й группе сравнения уменьшился на 74% (р&lt;0,0001), достиг нормального значения (64,6 (42,2;76,3)), в основной группе снизился на 43% и составил 406,7 (309,1; 498,6) пг/мл. </p></sec><sec><title>Выводы</title><p>Выводы. У пациентов всех групп выявлена повышенная концентрация NT-proBNP, наиболее высокая - в группе пациентов с ХСН на фоне ИБС и тиреотоксикоза. Определен новый пороговый уровень NT-proBNP – 556,4 пг/мл, позволяющий диагностировать ХСН у пациентов с сочетанием ИБС и тиреотоксикоза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to determine the cut-oﬀ of natriuretic peptide for optimization dyagnosis heart failure in comorbid patients with thyrotoxicosis, to assess the dynamics of this indicator during therapy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: 111 patients (58,3±5,6 years) were divided into 4 groups. Te main group consisted of 25 patients with CHD, CHF II-III FC and thyrotoxicosis; the 1st group of comparison - 30 patients with CHD and CHF II-III FC, without thyrotoxicosis; the 2nd group — 30 patients with thyrotoxicosis without CHD, the 3rd group - 26 patients with thyrotoxicosis and CHD, with no signs of CHF. Te fnding of thyroid gland, the level of NT-proBNP was estimated at baseline and afer 6 months therapy. A new cut-oﬀ NT-proBNP for the diagnosis of CHF in comorbid patients was calculated by using ROC analysis.</p></sec><sec><title>Results</title><p>Results: the high concentration of NT-proBNP was detected in all patients (more then 125 pg/ml), in the 2nd comparison group — 225.5 (180.1, 376.1) pg/ml. Te NT-proBNP values in the patients of the 1st and 3rd comparison groups did not diﬀer signifcantly. Te highest level of NT-proBNP was detected in the main group — 712.1 (434.3, 893.9) pg/ml. A cut-oﬀ of this marker for screening CHF in comorbid patients with CHD and thyrotoxicosis was calculated - 556.4 pg/ml (a sensitivity of 72 %, a specifcity of 100 %, an accuracy of 87.2 % (p &lt;0.001)). Afer 6 months therapy in the 2nd comparison group the level of NT-proBNP decreased by 74 % (р&lt;0,0001) and has reached the normal value (64,6 (42,2;76,3)); in the main group the level decreased by 43% and was 406,7 (309,1; 498,6) pg/ml.</p></sec><sec><title>Conclusions</title><p>Conclusions: the patients of all groups showed an increased concentration of NT-proBNP. Te highest level of NT-proBNP was observed in the group of patients with CHF by CHD and thyrotoxicosis. Te level of NT-proBNP was determined - 556.4 pg/ml, which allows us to diagnose CHF in patients with a combination of CHD and thyrotoxicosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>натрийуретические пептиды</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>коморбидные пациенты</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>тиреотоксикоз</kwd><kwd>пороговый уровень</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natriuretic peptide</kwd><kwd>chronic heart failure</kwd><kwd>comorbid patients</kwd><kwd>coronary heart desease</kwd><kwd>thyrotoxicosis</kwd><kwd>cut-oﬀ</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">Ларина В.Н., Чукаева И.И.
