On the 5th–7th day of myocardial infarction the values of echocardiographic parameters between the groups with and without right ventricular infarction did not differ significantly. Among patients with biventricular infarction in 40.9% of cases hypokinesis of the basal inferior segment of the right ventricle was visualized, in 9.1% – dilatation of the right ventricle, a large zone of local contractility impairment and global systolic dysfunction of both ventricles. The prognostic significance for unfavorable posthospital outcomes of inferior wall myocardial infarction was stenting of more than one coronary artery, decreased global circular deformation and visualization of more than four segments with impaired local contractility of the left ventricle (AUC 81.4%, sensitivity 69%, specificity 83%). Such unfavorable outcomes as recurrent myocardial infarction and necessity of aortocoronary bypass surgery are predicted by: hypokinesis of LV on echocardiography, ECG signs of right ventricular infarction, end-systolic volume index and left ventricular ejection fraction (AUC 71.9%, sensitivity 62%, specificity 70%).</p> <p><bold>Conclusion. </bold>Among echocardiographic signs of right ventricular involvement, hypokinesis of the basal inferior segment of the right ventricle was determined to be prognostically significant for one-year outcomes of inferior wall myocardial infarction of the left ventricle. Hypokinesis of the basal inferior segment of the right ventricle was visualized in 40.9% of patients with biventricular (according to ECG) inferior wall infarction, including 9.5% with extensive right ventricular infarction and right ventricular dilatation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель. </bold>Установить прогностически значимые для одногодичных исходов инфаркта миокарда нижней стенки левого желудочка (ИМНСЛЖ) эхокардиографические (ЭхоКГ) признаки вовлеченности правого желудочка (ПЖ).</p> <p><bold>Материалы и методы. </bold>Проведен многомерный математический анализ 184 показателей, в том числе 131 ЭхоКГ, 144 пациентов с ИМНСЛЖ.</p> <p><bold>Результаты. </bold>До чрескожного коронарного вмешательства признаки ИМПЖ по электрокардиографии (ЭКГ) – подъем<italic> ST</italic> в V<sub>3R</sub>–V<sub>4R</sub>-отведениях – присутствовали у 45,8% пациентов. На 5–7-й день ИМ значения ЭхоКГ-показателей между группами с инфарктом ПЖ и без него значимо не различались. Среди пациентов с бивентрикулярным инфарктом в 40,9% случаев визуализировали гипокинез базального нижнего сегмента ПЖ, в 9,1% – дилатацию ПЖ, обширную зону нарушения локальной сократимости и глобальную систолическую дисфункцию обоих желудочков. Прогностической значимостью для неблагоприятного постгоспитального исхода ИМНСЛЖ обладали: стентирование более одной коронарной артерии, снижение глобальной циркулярной деформации и визуализация более 4 сегментов с нарушением локальной сократимости ЛЖ (AUC 81,4%, чувствительность 69%, специфичность 83%). Формирование таких неблагоприятных исходов, как повторный ИМ и необходимость аортокоронарного шунтирования, прогнозируют: гипокинез ПЖ по ЭхоКГ, ЭКГ-признаки инфаркта ПЖ, значения индекса конечно-систолического объема и фракции выброса ЛЖ (AUC 71,9%, чувствительность 62%, специфичность 70%).</p> <p><bold>Заключение. </bold>Среди ЭхоКГ-признаков вовлеченности ПЖ прогностически значимым для одногодичных исходов ИМНСЛЖ определен гипокинез базального нижнего сегмента ПЖ. У 40,9% пациентов с бивентрикулярным (по ЭКГ) ИМНС визуализировали гипокинез базального нижнего сегмента ПЖ, в том числе у 9,5% – обширный инфаркт ПЖ с дилатацией ПЖ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>inferior wall myocardial infarction</kwd><kwd>right ventricle</kwd><kwd>prognosis</kwd><kwd>echocardiography</kwd><kwd>local contractility impairment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инфаркт миокарда нижней стенки</kwd><kwd>правый желудочек</kwd><kwd>прогноз</kwd><kwd>эхокардиография</kwd><kwd>нарушение локальной сократимости</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Patel M, Maheta D, Agrawal S, et al.
