В проспективное наблюдательное исследование включены 85 пациентов с пароксизмальной или персистирующей формой ФП и хронической одышкой, госпитализированных для проведения кардиоверсии. Всем участникам выполнялась трансторакальная эхокардиография в сочетании с методом спекл-трекинга для анализа продольной деформации левого предсердия (ПД ЛП). Вероятность СНсФВ оценивалась с помощью алгоритма HFA-PEFF. Для динамического наблюдения за пациентами были выделены три временные точки: во время фибрилляции предсердий, через 24 ч после кардиоверсии и через 1 мес наблюдения.</p></sec><sec><title>Результаты</title><p>Результаты. Высокая вероятность СНсФВ была выявлена у 78,7% пациентов (67 из 85). В этой группе зарегистрированы статистически значимо более высокие уровни NT-proBNP, более высокие баллы по шкале CHA₂DS₂-VASc, а также более низкие показатели ПД ЛП, более высокий индекс жесткости ЛП по сравнению с пациентами с низкой и промежуточной вероятностью СНсФВ. При динамическом наблюдении через 1 мес после кардиоверсии (n = 55) количество баллов по алгоритму HFA-PEFF оставалось неизменным, несмотря на статистически значимое снижение уровня NT-proBNP. Наибольшую прогностическую значимость для выявления пациентов с высокой вероятностью сердечной недостаточности продемонстрировал индекс жесткости ЛП, с отношением шансов 34,5 (95%-й доверительный интервал (ДИ) 2,5–478,7) во время ФП и 193,1 (95% ДИ 7,3–1207) при синусовом ритме.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные свидетельствуют о высокой распространенности ранее недиагностированной СНсФВ среди пациентов с ФП, госпитализированных для кардиоверсии. Вероятность СНсФВ существенно не изменялась в течение месяца после восстановления синусового ритма. Индекс жесткости ЛП обладает высокой диагностической ценностью для верификации СНсФВ у данной категории пациентов и может рассматриваться как дополнительный критерий при использовании стандартного алгоритма HFA-PEFF.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim was to evaluate the prevalence and echocardiographic predictors of previously undiagnosed heart failure with preserved ejection fraction (HFpEF) in patients with atrial fibrillation (AF) and chronic dyspnea.</p><sec><title>Material and methods</title><p>Material and methods. This prospective observational study included 85 patients hospitalized for cardioversion with paroxysmal or persistent AF and chronic dyspnea. All participants underwent transthoracic speckle-tracking echocardiography of left atrial longitudinal strain (LAS). HFpEF probability was assessed using the HFA-PEFF algorithm. Dynamic follow-up of diastolic function was performed at three predefined time points: during AF paroxysm, 24 hours post-cardioversion, and one-month post-cardioversion.</p></sec><sec><title>Results</title><p>Results. High probability of HFpEF was identified in 78.7% of patients (67 out of 85). These patients exhibited significantly higher NT-proBNP levels, greater CHA₂DS₂-VASc score, as well as more impaired LAS parameters and elevated left atrial stiffness index compared to low-intermediate HFpEF probability groups. At one-month follow-up after cardioversion (n = 55), while NT-proBNP levels significantly declined, overall HFpEF probability remained unchanged. Left atrial stiffness index demonstrated the strongest independent predictive value in verifying high probability HFpEF, with remarkable discriminative capacity both during AF (OR = 34.5; 95% CI 2.5–478.7) and after sinus rhythm restoration (OR = 193.1; 95% CI 7.3–1,207).</p></sec><sec><title>Conclusion</title><p>Conclusion. This study reveals high prevalence of undiagnosed HFpEF among AF patients undergoing cardioversion, with disease probability persisting despite rhythm control during one-month follow-up. The left atrial stiffness index is as a valuable diagnostic marker for HFpEF detection in this population, potentially enhancing standard HFA-PEFF algorithm.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>кардиоверсия</kwd><kwd>деформация левого предсердия</kwd><kwd>шкала HFA-PEFF</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>heart failure with preserved ejection fraction</kwd><kwd>cardioversion</kwd><kwd>left atrial strain</kwd><kwd>HFA-PEFF score</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">Reddy Y.N.V., Carter R.E., Obokata M., Redfield M.M., Borlaug B.A. A simple, evidence-based approach to help guide diagnosis of heart failure with preserved ejection fraction.
