Nevertheless, the diagnostic value of these markers and their threshold values require clarification.</p><sec><title>Objective</title><p>Objective: to present the characteristics of echocardiographic markers for atrial cardiopathy and the serum concentration of N-terminal pro-Btype natriuretic peptide (NT-proBNP) in embolic CS versus cardioembolic stroke (CES) and non-cardioembolic stroke (non-CES) to determine the threshold values of parameters with the highest sensitivity and specificity in differentiating CES and non-CES.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A total of 259 patients with ischemic stroke were examined. The standard examination additionally involved calculation of the parameters that reflected left atrial LA) function (LAF): LA emptying fraction (LAEF), and LA functional index (LAFI). The serum NT-proBNP concentration was also determined in 75 patients.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The patients with CES versus those with CS and non-CES were characterized by a considerable increase in LA diameter (4.3 [3.5; 4.5] cm vs 3.7 [3.4; 4.0] cm vs 3.7 [3.4; 3.9] cm; p=0.005 and p=0.009, respectively), LAVI (35.7 [30.5; 39.9] ml/m2 vs 28.5 [25.6; 34.6] ml/m2 vs 27.1 [24.5; 31.2] ml/m2 ; p&lt; 0.001) and NT-proBNP level (559 [409; 1144] pg/ml vs 164 [65; 308] pg/ml vs 191 [63; 446] pg/ml; p=0.002 and p=0.019, respectively), as well as by a lower LAEF value [50.3 [48.5; 51.1]% vs 54.7 [51.6; 56.6]% vs 54.9 [52.5; 56.8]%; p&lt; 0.001). The only parameter that showed significant differences between all the three groups (CES, CS, and nonCES) was LAFI (0.24 [0.2; 0.32] units vs 0.37 [0.3; 0.47] units vs 0.40 [0.34; 0.47] units; p&lt;0.00 1), while maintaining the differences in the values for the two groups (CS and non-CES) (p=0.004). The following threshold values of biomarkers were obtained for CES and nonCES; these were a LA diameter of 41.5 mm (p&lt; 0.001), a LAVI of 36.3 ml/m2 (p&lt; 0.001), a LAEF of 51.8% (p&lt; 0.001), a LAFI of 0.28 units (p&lt; 0.001), and an NT-proBNP of 316 pg/ml (p&lt; 0.001). Analysis of the ROC curves and the area under the curve (AUC) revealed that the most informative criteria for sensitivity and specificity were LAEF (79 and 88%, AUC 0.89), NT-proBNP (67 and 91%, AUC 0.89) and LAFI (93 and 72%, AUC 0.81).</p></sec><sec><title>Conclusion</title><p>Conclusion. The CS group and non-CES one are comparable in the echocardiographic manifestations of atrial cardiopathy and in serum NTproBNP values. LAEF and NT-proBNP concentrations are promising biomarkers to classify CS patients into potential arterio- and cardioembolic types.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Изучение биомаркеров предсердной кардиопатии представляется перспективным для выявления пациентов с криптогенным инсультом (КИ), при котором показан интенсивный поиск фибрилляции предсердий. Тем не менее диагностическая ценность данных маркеров и их пороговые значения требуют уточнения.</p><p>Цель исследования – представить характеристику эхокардиографических маркеров предсердной кардиопатии и концентрации про-натрийуретического N-концевого пептида В-типа (NT-proBNP) в сыворотке крови при эмболическом КИ в сравнении с кардиоэмболическим (КЭИ) и некардиоэмболическим (неКЭИ) подтипами инсульта, определить пороговые значения показателей, обладающих наибольшей чувствительностью и специфичностью при дифференциации КЭИ и неКЭИ.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Обследовано 259 пациентов с ишемическим инсультом. В дополнение к стандартному обследованию проводилось вычисление показателей, отражающих функцию левого предсердия (ЛП): фракции опорожнения ЛП (left atrial emptying fraction, LAEF), функционального индекса ЛП (left atrial function index, LAFI), – и у 75 пациентов определена сывороточная концентрация NT-proBNP.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Пациенты с КЭИ, в отличие от больных с КИ и неКЭИ, характеризовались значимым увеличением диаметра ЛП (4,3 [3,5; 4,5] см vs 3,7 [3,4; 4,0] см vs 3,7 [3,4; 3,9] см; p=0,005 и p=0,009 соответственно), LAVI (35,7 [30,5; 39,9] мл/м2 vs 28,5 [25,6; 34,6] мл/м2 vs 27,1 [24,5; 31,2] мл/м2; p&lt; 0,001) и уровнем NT-proBNP (559 [409; 1144] пг/мл vs 164 [65; 308] пг/мл vs 191 [63; 446] пг/мл; p=0,002 и p=0,019 соответственно), а также меньшим значением LAEF [50,3 [48,5; 51,1] % vs 54,7 [51,6; 56,6] % vs 54,9 [52,5; 56,8] %; p&lt; 0,001). Единственным параметром, по которому выявлены достоверные различия между всеми тремя группами (КЭИ – КИ – неКЭИ), было значение LAFI (0,24 [0,2; 0,32] ед. vs 0,37 [0,3; 0,47] ед. vs 0,40 [0,34; 0,47] ед.; p&lt; 0,001), с сохранением различий показателя и для двух групп КИ vs неКЭИ (p=0,004). В отношении дифференциации КЭИ и неКЭИ получены следующие пороговые значения биомаркеров: диаметр ЛП 41,5 мм (p&lt;0,001), LAFI 0,28 ед. (p&lt; 0,001), NT-proBNP 316 пг/мл (p&lt; 0,001). При анализе ROC-кривых и площади под кривой выявлено, что по критериям чувствительности и специфичности наиболее информативными являются LAEF (79 и 88%, AUC 0,89), NT-proBNP (67 и 91%, AUC 0,89) и LAFI (93 и 72%, AUC 0,81).</p></sec><sec><title>Заключение</title><p>Заключение. Группы пациентов с КИ и неКЭИ сопоставимы по эхокардиографическим проявлениям предсердной кардиопатии и значениям сывороточной концентрации NT-proBNP. Перспективными биомаркерами для категоризации пациентов с КИ на возможный артерио- и кардиоэмболический варианты служат LAEF и концентрация NT-proBNP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>предсердная кардиопатия</kwd><kwd>криптогенный инсульт</kwd><kwd>биомаркеры</kwd><kwd>эхокардиография</kwd><kwd>LAEF</kwd><kwd>NT-proBNP</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial cardiopathy</kwd><kwd>cryptogenic stroke</kwd><kwd>biomarkers</kwd><kwd>echocardiography</kwd><kwd>left atrial emptying fraction</kwd><kwd>NT-proBNP</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">Nouh A, Hussain M, Mehta T, Yaghi S.
