Применение предложенного актуальными рекомендациями алгоритма (ASE/EACVI, 2016), предполагающего оценку трансмитрального потока, тканевых допплеровских скоростей движения миокарда, индекса максимального объема левого предсердия (ИоЛП) и скорости струи трикуспидальной регургитации (ТР), приводит к тому, что наличие и тяжесть диастолической дисфункции (ДДФ) ЛЖ остаются неопределенными у значительной части пациентов. Индекс объема левого предсердия безусловно является маркером длительности существования и тяжести ДДФ ЛЖ, однако он не может служить единственным параметром для диагностики ранних фаз диастолической дисфункции ЛЖ, до формирования ремоделирования левого предсердия (ЛП). Определение функции ЛП является важной частью при оценке ДФ ЛЖ и сердечной недостаточности с сохраненной фракцией выброса (СНсФВ). Поскольку основной функцией ЛП является модуляция наполнения ЛЖ, логично, что на самых ранних стадиях ДДФ ЛЖ, сначала появляются именно функциональные изменения ЛП. Исследование функции ЛП может быть полезным не только для диагностики ДДФ ЛЖ, но и для оценки степени ее тяжести, а также и для мониторинга эффективности лечения. В настоящей статье рассматривается эволюция подходов к оценке ДФ ЛЖ, а также обосновывается ключевая роль показателей ЛП в оценке ДДФ ЛЖ.</p></abstract><trans-abstract xml:lang="en"><p>Echocardiographic (EchoCG) assessment of LV DF remains a complex difficult task. The application of the algorithm proposed by current guidelines (ASE/EACVI, 2016), which involves the assessment of transmitral flow, tissue Doppler myocardial velocities, LA maximum volume index, LAVI, and tricuspid regurgitation (TR) velocity, leads to the fact that the presence and severity of LV diastolic dysfunction (DDF) remain uncertain in a significant proportion of patients. The maximum LAVI index is certainly a marker of the duration and severity of LV DDF, but it cannot serve as the only parameter for diagnosing early phases of LV DDF, before the formation of LA remodeling. Left atrial (LA) function assessment is an important part of the left ventricular (LV) diastolic dysfunction (DF) the assessment and heart failure with preserved ejection fraction. Since the main function of the LA is to modulate LV filling, it is logical that at the earliest stages of LV DDF, LA functional changes first appear. LA function testing may be useful not only for diagnosing LV DDF, but also for assessing its severity and monitoring treatment effectiveness. In this review the evolution of approaches to assessing LV DF, as well as the key role of LA parameters in assessing LV DDF are considered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность с сохраненной фракцией выброса</kwd><kwd>левое предсердие</kwd><kwd>диастолическая дисфункция левого желудочка</kwd><kwd>фазовая функция</kwd><kwd>спекл-трекинг-эхокардиография</kwd><kwd>индекс объема левого предсердия</kwd><kwd>стрейн резервуара</kwd><kwd>стрейн кондуита</kwd><kwd>стрейн сокращения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure with preserved ejection fraction</kwd><kwd>left atrium</kwd><kwd>left ventricular diastolic disfunction</kwd><kwd>phasic function</kwd><kwd>speckle-tracking echocardiography</kwd><kwd>left atrial volume index</kwd><kwd>strain during reservoir</kwd><kwd>conduit</kwd><kwd>contraction phase</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">Эхокардиография.
