Снижение контрактильного резерва по обоим показателям (ФВ и GLS) выявлено в группе пациентов с тяжелым АС, что в сочетании со значимым стресс-индуцированным увеличением градиента на АК (≥18–20 мм рт. ст.), нарастанием СДЛА (&gt;60 мм рт. ст.) и снижением АД (&gt;20 мм рт. ст.) в соответствии с рекомендациями EACVI/ASE (2017) следует рассматривать как предикторы неблагоприятного прогноза естественного течения заболевания аортального клапана, а пациентов с подобными результатами нагрузочного теста — как возможных кандидатов на хирургическое лечение. Снижение прироста индекса эластичности ЛЖ на фоне ФН, которое было взаимосвязано с изменением других рассмотренных параметров сократимости, а также мощностью выполненной нагрузки в МЕТ, существенно дополняет функциональную характеристику поражения и способствует оптимальной стратегии ведения. Следовательно, стресс-эхокардиография с физической нагрузкой является незаменимым диагностическим инструментом для определения прогноза и сроков проведения хирургического вмешательства у пациентов с аортальным стенозом.</p></abstract><trans-abstract xml:lang="en"><p>In order to determine the clinical significance of exercise stress echocardiography in patients with severe to moderate aortic stenosis, a stress-induced increase in the mean pressure gradient across the aortic valve was recorded and myocardial contractile reserve was assessed using a number of parameters (ejection fraction, global longitudinal strain, elasticity index). It was found that, with normal values of EF at rest in patients with severe and moderate aortic stenosis, the deficit in contractile function was revealed using the GLS index, which demonstrated a decrease in both groups at the peak of exercise. A decrease in contractile reserve by both parameters (EF and GLS) was found in the group of patients with severe AS, which, combined with a significant stress-induced increase in the gradient on the aortic valve (≥18–20 mm Hg), an increase in pulmonary artery pressure (&gt;  60 mm Hg) and decrease in systemic systolic blood pressure (&gt;20 mm Hg) should be considered as a predictors of a poor prognosis of the natural course of aortic valve disease, and patients with similar stress test results should be possible candidates for surgical aortic valve replacement. A decrease in the in the LV elasticity index augmentation at the peak of exercise, strongly correlated with changes in other considered parameters of contractility and the metabolic power of exercise (MET), significantly complements the functional characteristics of the lesion for choosing the optimal management strategy. Consequently, exercise stress echocardiography is an indispensable diagnostic tool for determining the prognosis and timing of surgery in patients with aortic stenosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стресс-эхокардиография</kwd><kwd>аортальный стеноз</kwd><kwd>глобальная продольная деформация</kwd><kwd>фракция выброса</kwd><kwd>индекс эластичности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress echocardiography</kwd><kwd>aortic stenosis</kwd><kwd>global longitudinal strain</kwd><kwd>ejection fraction</kwd><kwd>elasticity index</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">Martinsson A., Li X., Andersson C. et al.
