Анализ дефектов контрастирования миокарда по данным мультиспиральной компьютерной томографии (МСКТ) у больных с острым коронарным синдромом (ОКС) без стойкого подъема сегмента ST и сопоставление полученных данных с результатами стандартных методов диагностики инфаркта и ишемии миокарда - электрокардиографии (ЭКГ) и эхокардиографии (ЭхоКГ). Материалы и методы. В исследование включено 43 пациента с ОКС без подъема сегмента ST, в том числе 21 пациент с нестабильной стенокардией (НС) и 22 - с инфарктом миокарда (ИМ). МСКТ с внутривенным контрастированием выполнялась перед инвазивной коронароангиографией (КАГ) и реваскуляризацией миокарда на томографе с 64 рядами детекторов при ретроспективной синхронизации с ЭКГ Повторная МСКТ проводилась пациентам с НС и выявленным при первичном исследовании дефектом контрастирования миокарда для оценки динамики. В последующем проводилось сопоставление зон гипоконтрастирования по данным МСКТ с ишемическими изменениями сегмента ST на ЭКГ и зонами нарушенной локальной сократимости миокарда по данным ЭхоКГ Результаты. Дефекты контрастирования выявляли у 21 (48,8%) из 43 пациентов с ОКС. У больных с ИМ зоны гипоконтрастирования определялись в 18 (85,7%) случаях из 21, в то время как у больных с НС - только у 3 (13,6%) из 22 (p&lt;0,01). У пациентов с ИМ дефект контрастирования расценивали как очаг некроза сердечной мышцы, тогда как у пациентов с НС выявление зоны гипоконтрастирования могло указывать на наличие как недиагностированного очагового повреждения, так и ишемии. Известно, что при ишемии миокарда восстановление коронарного кровотока сопровождается исчезновением дефекта контрастирования при повторной МСКТ, тогда как при некрозе миокарда дефект остается неизменным и по прошествии многих месяцев. Для уточнения природы дефектов контрастирования у больных с НС всем пациентам из этой группы, у которых исходно определялись зоны гипоконтрастирования (n=3), была выполнена повторная МСКТ через 1 год для оценки изменений размера очага. В 2 случаях отмечалась положительная динамика в виде исчезновения (n=1) и уменьшения размеров (n=1) дефекта контрастирования после успешной реваскуляризации. Это свидетельствовало о том, что исходно они были обусловлены ишемией миокарда, тогда как в третьем случае, в котором изменений размеров дефекта не отмечалось, - недиагностированным очаговым повреждением миокарда. У большинства больных с дефектами контрастирования миокарда на электрокардиограмме регистрировалась ишемическая динамика сегмента ST - у 78% пациентов с ИМ и 66,7% - с НС. При этом во всех случаях отмечалось совпадение локализации зон гипоконтрастирования по данным МСКТ и ишемических изменений сегмента ST на электрокардиограмме, а также зон нарушения локальной сократимости по данным ЭхоКГ. Выявление дефектов контрастирования и зон нарушения локальной сократимости достоверно коррелировало между собой, как по частоте (r=0,4; p=0,01), так и по количеству вовлеченных сегментов (r=0,7; p&lt;0,05). Заключение. Дефекты контрастирования, выявленные по данным МСКТ, могут отражать наличие не только очагового повреждения миокарда, но и выраженной ишемии. Критериями «ишемических» дефектов являются их преходящий характер и исчезновение после реваскуляризации миокарда. У большинства пациентов с дефектами контрастирования миокарда по данным других методов исследования (ЭКГ и ЭхоКГ) также определяются признаки очагового повреждения миокарда и ишемии.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of our study was analysis of myocardial hypoenhancement areas (MHAs) found by multidetector computed tomography (MDCT) in patients with non-ST elevation acute coronary syndrome (NSTEACS) and comparison of these findings with results of standard methods of diagnostics of myocardial infarction and ischemia [electrocardiography (ECG) and echocardiography (ECHO)]. Methods. MHAs were found in 18 of 21 patients with non-ST segment elevation myocardial infarction (NSTEMI) (85.7%) and only in 3 of 22 patients with unstable angina (UA) (13.6%, p&lt;0.0l). In patients with NSTEMI MHAs were interpreted as foci of myocardial necrosis while in patients with UA MHAs could represent either undiagnosed myocardial damage or myocardial ischemia. It was shown previously that “ischemic” MHAs disappear after successful revascularization, whereas defects caused by necrosis remain unchanged for many months. Patients with UA and MHAs (n=3) underwent MDCT in 1 year after revascularization. In 1 patient MHA disappeared and in 1 it decreased in size. In these cases, probably, MHAs represented myocardial ischemia where. In the 3-rd patient the defect size remained unchanged and was considered to be a sign of undiagnosed NSTEMI. Most patients with MHAs had ST-segment ECG dynamics (78% of patients with NSTEMI, 66.7% of patients with UA). In all cases, localization of ST-segment deviation on ECG, myocardial wall motion abnormalities at ECHO and MHAs by MDCT coincided. Detection of MHAs and wall motion abnormalities correlated with each other as the frequency of occurrence (r=0.4; p=0.01), and number of segments involved (r =0.7; p&lt;0.05).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>МСКТ</kwd><kwd>острый коронарный синдром</kwd><kwd>дефекты контрастирования миокарда</kwd><kwd>зоны гипоконтрастирования</kwd><kwd>ишемия миокарда</kwd><kwd>инфаркт миокарда</kwd><kwd>нестабильная стенокардия</kwd><kwd>зоны нарушения локальной сократимости</kwd><kwd>эхокардиография</kwd><kwd>multidetector computed tomography (MDCT)</kwd><kwd>acute coronary syndrome</kwd><kwd>myocardial hypoenhancement areas</kwd><kwd>myocardial perfusion defect</kwd><kwd>myocardial ischemia</kwd><kwd>myocardial infarction</kwd><kwd>unstable angina</kwd><kwd>wall motion abnormalities</kwd><kwd>echocardiography</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">Baks T., Cademartiri F., Moelker A.D. et al.
