Для оценки прогноза острого инфаркта миокарда (ОИМ) главную роль играют фракция выброса (ФВ), диастолическая дисфункция левого желудочка (ЛЖ) и его объемы. Измерение деформации левого предсердия (ЛП) является новым методом неинвазивного исследования его механической функции.Цель исследования: изучение механической функции ЛП у больных ОИМ при различной степени снижения ФВ ЛЖ.Материал и методы исследования. Нами исследованы 60 пациентов с ОИМ с подъемом сегмента ST передней локализации. Эхокардиография проводилась в первые сутки ОИМ. ЛП оценивалось по фазовым объемам, а также по деформации и скорости деформации с помощью спекл-трекинга. Для контроля исследованы 35 здоровых людей. Пациенты разделены на 4 группы: 1-я группа – ФВ ЛЖ 50–60%, 2-я группа – ФВ ЛЖ 40–49%, 3-я группа – ФВ ЛЖ 30–39%, 4-я группа – ФВ ЛЖ 20–29%.Результаты. Достоверных различий в объемах ЛП между пациентами 1–3-й групп и здоровыми добровольцами не было. В 4-й группе объем ЛП был увеличен. В 1-й группе пиковая продольная деформация (PALS) была снижена в сравнении с контролем (PALS 22% vs 32,4%, р &lt; 0,000). Во 2-й группе PALS составила 17,41%, в 3-й – 18,19% (р &lt; 0,000). В 4-й группе PALS была 4,43% (р &lt; 0,000). У здоровых испытуемых скорость деформации была 2,14 см/с–1, в 1-й группе – 2,15 см/с–1 (р &lt; 0,297), во 2-й – 1,19 см/с–1(р &lt; 0,000), в 3-й – 1,58 см/с–1 (р &lt; 0,000), в 4-й – 1,14 см/с1 (р &lt; 0,000).Выводы. У пациентов с ОИМ с ФВ ЛЖ более 50% выявляются достоверные нарушения деформации ЛП, что может быть предиктором развития дисфункции левых отделов сердца. По мере снижения ФВ ЛЖ степень нарушения деформации и объем ЛП постепенно увеличиваются.</p></abstract><trans-abstract xml:lang="en"><p>Background. The ejection fraction (EF), diastolic dysfunction of the left ventricle (LV) and its volumes play the main role for prognosis assessment. Measurement of left atrial strain is a new method of noninvasive investigation of mechanical function.Aim: To investigate the mechanical function of the left atrium in patients with acute myocardial infarction (AMI) with different degrees of left ventricular ejection fraction reduction.Methods. We studied 60 patients with acute ST-segment elevation anterior myocardial infarction. Echocardiography was performed in the first day of acute infarction. The left atrium was assessed by phase volumes, as well as by strain and strain rate using speckle-tracking. 35 healthy subjects were investigated for control. The patients were divided into 4 groups: Group 1 – LV EF 50–60%, Group 2 – LV EF 40–49%, Group 3 – LV EF 30–39%, Group 4 – LV EF 20–29%.Results. There were no significant differences in left atrial volumes between patients in groups 1–3 and healthy patients. Left atrial volume was increased in the fourth group. In the first group, peak longitudinal atrial strain (PALS) was significantly reduced compared with control group (PALS 22% vs 32.4%, p &lt; 0.000). In the second group PALS was 17.41%, in the third group it was 18.19%. In the group with LV EF less than 30%, PALS was 4.43%. In healthy subjects, the strain rate was – 2.14 cm/s-1, in Group 1 – 2.15 cm/s-1 (p &lt; 0.297), in Group 2 – 1.19 cm/s-1(p &lt; 0.000), in Group 3 – 1.58 cm/s-1 (p &lt; 0.000), and in Group 4 – 1.14 cm/s-1(p &lt; 0.000).Conclusion. In patients with AMI with LV EF more than 50%, significant violations of LA strain are detected, which may be a predictor of left heart dysfunction. As the LV EF decreases, LA strain decreases and LA volume increases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острый инфаркт миокарда</kwd><kwd>сердечная недостаточность</kwd><kwd>деформация левого предсердия</kwd><kwd>Speckle Tracking</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute myocardial infarction</kwd><kwd>heart failure</kwd><kwd>left atrial strain</kwd><kwd>Speckle Tracking</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">Legallois D., Hodzic A., Milliez P., Manrique A., Dolladille C., Saloux E. et al.
