На ЭКГ при поступлении сохранялась полная блокада правой ножки пучка Гиса, атриовентрикулярная блокада I степени. Пациенту выполнена трансторакальная эхокардиография (ЭхоКГ) и спекл-трекинг (СТ) ЭхоКГ с оценкой показателей продольной деформации и миокардиальной работы левого желудочка (МР ЛЖ): индекса миокардиальной работы (MWI), конструктивной, потерянной работ и эффективности миокардиальной работы (MWE). По данным стандартной ЭхоКГ фракция выброса левого желудочка (ФВ ЛЖ) составляло 45%, отмечались нарушения локальной сократимости передне-перегородочной локализации. Эти данные были дополнены снижением индекса глобальной продольной деформации (GLS = -14,2%), снижением региональных значений пиковой систолической продольной деформации ≥-14%, уменьшением площади петель “давление–деформация” c наклоном их вправо, характерным для ишемии, со снижением глобальных и сегментарных значений MWI и MWE ЛЖ по передне-перегородочной области ЛЖ на всех уровнях. При дообследовании – повышение тропонина I до 3,5 нг/мл. По результатам коронароангиографии (КАГ) – субокклюзия передней межжелудочковой ветви в проксимальной трети, выполнена транслюминальная баллонная ангиопластика со стентированием.</p><p>На следующие сутки в связи с элевацией сегмента ST в грудных отведениях проведена контрольная КАГ: ранее установленный стент без признаков тромбоза. Диагноз трансформирован в “острый инфаркт миокарда с подъемом сегмента ST”. При СТ-ЭхоКГ с оценкой МР ЛЖ отмечалась некоторая положительная динамика, подтверждающая данные контрольной КАГ.</p><p>При малой информативности ЭКГ-диагностики определение параметров глобальной и региональной продольной деформации и МР ЛЖ позволило уточнить распространенность повреждения миокарда, сократить задержку инвазивной диагностики и лечения, оценить результаты в динамике.</p></abstract><trans-abstract xml:lang="en"><p>The article presents a clinical case of a patient with previously diagnosed right bundle branch block hospitalized with a diagnosis of non-ST-segment elevation acute coronary syndrome (NSTE-ACS). The ECG on admission showed complete right bundle branch block and first-degree atrioventricular (AV) block. The patient underwent transthoracic echocardiography (EchoCG) and speckle-tracking (ST) echocardiography to assess longitudinal strain and left ventricular myocardial work (LVMW): myocardial work index (MWI), constructive work, wasted work, and myocardial work efficiency (MWE). According to standard echocardiography, the left ventricular ejection fraction (LVEF) was 45%, with local contractility disorders in the anteroseptal region. These data were complemented by a decrease in the global longitudinal strain index (GLS = -14.2%), a decrease in regional peak systolic longitudinal strain values ≥-14%, a decrease in the area of the pressure-strain loops with their shift and slight inclination to the right, characteristic of ischemia, and a decrease in global and segmental LV MWI and MWE values in the LV anteroseptal region at all levels. Further examination revealed an increase in troponin I to 3.5 ng/ml. Coronary angiography (CAG) revealed subocclusion of the anterior interventricular branch in the proximal third; transluminal balloon angioplasty with stenting was performed. The following day, a control coronary angiography (CAG) was performed due to ST-segment elevation in the chest leads. The previously inserted stent showed no signs of thrombosis. The diagnosis was updated to "acute myocardial infarction with ST-segment elevation." A CAG echocardiogram (EchoCG) with LV MRI showed some improvement, confirming the findings of the control CAG.Given the limited information provided by ECG diagnostics, determining the parameters of global and regional longitudinal strain and LV MRI allowed us to clarify the extent of myocardial damage, reduce the delay in invasive diagnosis and treatment, and evaluate the results over time.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>блокада правой ножки пучка Гиса</kwd><kwd>острый коронарный синдром</kwd><kwd>продольная деформация</kwd><kwd>постсистолический индекс</kwd><kwd>миокардиальная работа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>right bundle branch block</kwd><kwd>acute coronary syndrome</kwd><kwd>longitudinal strain</kwd><kwd>postsystolic index</kwd><kwd>myocardial work</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">нет</funding-statement><funding-statement xml:lang="en">нет</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Widimsky P., Rohác F., Stásek J. et al.
