— изучить влияние локализации гемодинамически значимого коронарного стеноза на глобальные показатели деформации миокарда левого желудочка у пациентов с умеренной предтестовой вероятностью (ПТВ) ишемической болезни сердца (ИБС).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 79 пациентов с умеренной ПТВ ИБС (медиана возраста 62,0 года, мужчин 52), которым были выполнены стресс-эхокардиографическое исследование и в течение 2 месяцев после этого — инвазивная коронарная ангиография. После стресс-эхокардиографии методом спекл-трекинг ЭхоКГ определялись значения глобального продольного стрейна (ГПС) и глобального постсистолического индекса (ГПСИ). Гемодинамически значимые коронарные стенозы были выявлены у 53 пациентов, в том числе стеноз передней межжелудочковой ветви (ПМЖВ)— у 23 пациентов, огибающей ветви (ОВ) — у 16, правой коронарной артерии (ПКА) — у 14.</p></sec><sec><title>Результаты</title><p>Результаты. У больных с коронарным стенозом медианные значения ГПС были ниже, чем у пациентов без стеноза в условиях покоя (18,8 против 21,9%, р = 0,0003) и после физической нагрузки (20,3 против 24,3%, р = 0,0001). Медианные значения ГПСИ при наличии стеноза были выше, чем при его отсутствии (в покое 2,94 против 1,62%, р = 0,0091, после нагрузки – 7,88 против 1,35%, р &lt;0,0001). Значения ГПС в покое при стенозе ПМЖВ, ОВ и ПКА равнялись 18,4%, 18,5% и 20,0% (р = 0,0008), после нагрузки — 16,9%, 21,1% и 24,3% (р &lt;0,0001). Соответствующие значения ГПСИ в покое равнялись 2,88%, 5,18% и 2,77% (р = 0,0126), после нагрузки — 8,24%, 7,85% и 4,59% (р &lt;0,0001). При стенозе ПКА значения ПГС в покое и после нагрузки и значение ГПСИ в покое статистически значимо не отличались от показателей пациентов без коронарного стеноза.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с умеренной ПТВ ИБС глобальные показатели деформации миокарда левого желудочка зависят не только от наличия гемодинамически значимого коронарного стеноза, но и от его локализации. Наиболее выраженное снижение ГПС и возрастание ГПСИ отмечается при стенозе ПМЖВ, наименее выраженное — при стенозе ПКА.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Resume</title><p>Resume </p><p>The aimwas to study the impact of localization of hemodynamicallysignificantcoronarystenosisongloballeftventricular strain in patientswith a moderatepre—test probability (PTP) of coronary heart disease (CHD).</p></sec><sec><title>Materials and methods</title><p>Materials and methods.Thestudyincluded79patientswithmoderatePTPCHD(medianage62.0years,52men)whounderwentstress echocardiography(stress-EchoCG)and within 2 months invasivecoronaryangiography.

In patients with moderate PTP CHD, the global left ventricular strain indicators depend not only on the presence of hemodynamically significant coronary stenosis, but also on localization. The most pronounced decrease in GLS and an increase in GPSI were observed in patients with stenosis of ADA, the least pronounced – in patients with stenosis of the PCA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>умеренная предтестовая вероятность</kwd><kwd>стресс-эхокардиография</kwd><kwd>спекл-трекинг эхокардиография</kwd><kwd>глобальный продольный стрейн</kwd><kwd>глобальный постсистолический индекс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary heart disease</kwd><kwd>moderate pre-test probability</kwd><kwd>stress echocardiography</kwd><kwd>speckle-tracking echocardiography</kwd><kwd>global longitudinal strain</kwd><kwd>global postsystolic index</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">нет</funding-statement><funding-statement xml:lang="en">no</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">Литература</mixed-citation><mixed-citation xml:lang="en">References</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Barbarash OL, Karpov YuA, Panov AV, et al. 2024 Clinical practice guidelines for Stable coronary artery disease.
