Изучить возможности анализа индекса жесткости левого предсердия (Left Atrial Stiffness Index, LASI) при эхокардиографии (ЭхоКГ) покоя в диагностике сердечной недостаточности с сохра­ненной фракцией выброса (СНсФВ) в зависимости от результата диастолического стресс-теста (ДСТ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. ДСТ проводили при недостаточном коли­честве критериев для заключения о повышенном давлении запол­нения левого желудочка по данным традиционной ЭхоКГ покоя. Обследовано 100 больных (52,0% мужчин, 66,1±5,4 года); пациенты с отношением E/e' (отношение ранней диастолической скоро­сти трансмитрального потока (Е) к ранней диастолической скоро­сти движения фиброзного кольца митрального клапана (е')) &gt;15 при ДСТ составили группу I (n=45), пациенты c E/e' &lt;15 — группу II (n=55). Метод отслеживания движения пятен (speckle tracking echo) использован для оценки деформации резервуарной фазы левого предсердия (left atrial reservoir strain, LASr).</p></sec><sec><title>Результаты</title><p>Результаты. Между группами были выявлены статистически зна­чимые различия по полу (40,0% мужчин в группе I и 61,8% в группе II, соответственно; р=0,044), индексу массы тела (32,9 [29,5;36,0] и 29,6 [27,3;31,8] кг/м2; р=0,001), стадии артериальной гипертонии (2,9±0,3 и 2,5±0,8, р=0,037), наличию ишемической болезни серд­ца (88,9 и 67,3%; р=0,016), функциональному классу хронической сердечной недостаточности по NYHA (New York Heart Association) (2,0±0,4 и 1,5±0,7; р=0,003). При проведении ЭхоКГ покоя выяв­лены достоверные различия по индексу объема левого предсер­дия (31,9 [28,5;36,0] и 27,8 [24,1;34,6] мл/м2; р=0,039), отношению E/e' (10,9 [9,7;12,5] и 9,3 [7,4;10,8]; р&lt;0,001), LASr (23,5 [19,3;28,3] и 28,9 [25,6;32,2]%, р&lt;0,001) и LASI (0,46 [0,38;0,56] и 0,30 [0,25;0,39]; р&lt;0,001). При проведении ROC-анализа наибольшая площадь под кривой (AUC), оптимальные чувствительность и специ­фичность в определении СНсФВ наблюдались у LASI (AUC=0,829, р&lt;0,001; 77,8 и 74,5%, соответственно); меньшие значения каче­ства классификации показала шкала H2FPEF (шкала для диагно­стики сердечной недостаточности с сохраненной фракцией выбро­са Американской ассоциации кардиологов (предложена клиникой Mayo, 2018)) (AUC=0,701, р=0,001; 66,7 и 69,1%); алгоритм HFA-PEFF (Heart Failure Association score) не имел достоверной значи­мости в претестовом выявлении СНсФВ (AUC=0,608, р=0,065; 53,3 и 61,8%).</p></sec><sec><title>Заключение</title><p>Заключение. LASI с точкой отсечения &gt;0,38 имеет наибольшую способность в определении СНсФВ среди возможных методов ее претестовой диагностики.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the diagnostic value of the left atrial stiffness index (LASI) of heart failure with preserved ejection fraction (HFpEF) depending assessed by transthoracic echocardiography (TTE) in the diagnosis on diastolic stress test (DST) results.</p></sec><sec><title>Material and methods</title><p>Material and methods. DST was performed in cases of insufficient criteria for increased left ventricular filling pressure assessed by TTE. One hundred patients were examined (52,0% men, 66,1±5,4 years). Patients with a ratio of early transmitral flow velocity to early diastolic mitral annulus velocity (E/e') ratio &gt;15 in DST were included in group I (n=45), patients with E/e' &lt;15 — group II (n=55). The speckle tracking echocardiography was used to assess left atrial reservoir strain (LASr).</p></sec><sec><title>Results</title><p>Results. Significant differences were identified between the groups in sex (40,0% of men in group I and 61,8% in group II, respectively; p=0,044), body mass index (32,9 [29,5;36,0] and 29,6 [27,3;31,8] kg/m2; p=0,001), hypertension stage (2,9±0,3 and 2,5±0,8, p=0,037), the presence of coronary artery disease (88,9 and 67,3%; p=0,016), NYHA heart failure class (2,0±0,4 and 1,5±0,7; p=0,003). TTE re­vealed significant differences in the left atrium volume index (31,9 [28,5;36,0] and 27,8 [24,1;34,6] ml/m2; p=0,039), E/e' ratio (10,9 [9,7;12,5] and 9,3 [7,4;10,8]; p&lt;0,001), LASr (23,5 [19,3;28,3] and 28,9 [25,6;32,2]%, p&lt;0,001) and LASI (0,46 [0,38;0,56] and 0,30 [0,25;0,39]; p&lt;0,001). According to ROC analysis, the largest area under the curve (AUC), optimal sensitivity and specificity in HFpEF diagnosis were observed in LASI (AUC=0,829, p&lt;0,001; 77,8 and 74,5%, respectively). Lower classification quality was shown by the H2FPEF score (AUC=0,701, p=0,001; 66,7 and 69,1%), while the HFA-PEFF score was not significant in the pretest detection of HFpEF (AUC=0,608, p=0,065; 53,3 and 61,8%).</p></sec><sec><title>Conclusion</title><p>Conclusion. LASI with a cut-off point &gt;0,38 has the greatest ability to detect HFpEF among the possible pretest diagnostic methods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>левое предсердие</kwd><kwd>индекс жесткости левого предсердия</kwd><kwd>диастолическая дисфункция</kwd><kwd>диастолический стресс-тест</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure with preserved ejection fraction</kwd><kwd>left atrium</kwd><kwd>left atrial stiffness index</kwd><kwd>diastolic dysfunction</kwd><kwd>diastolic stress test</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">Овчинников А.Г., Агеев Ф.Т., Алёхин М.Н. и др.
