Определить значимость различных факторов риска для прогнозирования развития инфаркта миокарда (ИМ) при выполнении операции каротидной эндартерэктомии (КЭАЭ) у пациентов с ишемической болезнью сердца (ИБС) высокого риска.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровое когортное проспективное исследование включено 204 больных с ИБС высокого риска, у которых была установлена необходимость выполнения операции КЭАЭ. Перед операцией всем больным проводилась медикаментозная коррекция ИБС, и все больные были клинически стабилизированы. Первым этапом выполнялась КЭАЭ. Были изучены клинические и диагностические факторы, связанные с риском развития периоперационного ИМ. Конечными точками исследования были: инсульт, ИМ, летальный исход от ИМ. Диагноз ИМ устанавливали при наличии сочетания повышения уровня тропонина cTn-I выше 99-го процентиля верхнего референсного предела с электрокардиографическими признаками ишемии миокарда, либо с болью в грудной клетке или эквивалентными симптомами и признаками, соответствующими ишемии миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. Инсультов не было. Летальности, связанной с ИМ, не было. Периоперационный ИМ развился у 8 (3,9%) пациентов. Установлено, что наиболее значимыми показателями для прогнозирования периоперационного ИМ оказались: наличие выраженных нарушений локальной сократимости левого желудочка (ЛЖ) (отношение рисков (ОР) 13,570; 95% доверительный интервал (ДИ) 1,427-124,782, р&lt;0,05) и снижение фракции выброса ЛЖ &lt;50% (ОР 10,909; 95% ДИ 1,052-271,229, р&lt;0,05). Тогда как такие факторы, как: баллы по шкале SYNTAX, перенесённое острое нарушение мозгового кровообращения, перенесенный ИМ, наличие инсулинозависимого сахарного диабета, ожирения, хронической обструктивной болезни легких, оказались статистически незначимы для прогнозирования периоперационного ИМ (р&gt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ИБС высокого риска наличие выраженных нарушений локальной сократимости и снижение глобальной систолической функции ЛЖ являются наиболее значимыми факторами риска развития периоперационного ИМ при проведении КЭАЭ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To determine the value of various risk factors for predicting the myocardial infarction (MI) during carotid endarterectomy in high-risk patients with coronary artery disease (CAD).</p></sec><sec><title>Material and methods</title><p>Material and methods. The single-center cohort prospective study included 204 high-risk patients with CAD who required carotid endarterectomy (CEA). Before surgery, all patients underwent treatment of CAD, and all patients were clinically stabilized. The first step was CEA. Clinical and diagnostic factors associated with the risk of perioperative MI were studied. There were following end points of the study: stroke, MI, death due to MI. The diagnosis of MI was established when there was a combination of an increase in cTn-I troponin above the 99th percentile upper reference limit with electrocardiographic manifestations of myocardial ischemia, or with chest pain or equivalent symptoms consistent with myocardial ischemia.</p></sec><sec><title>Results</title><p>Results. There were no strokes. There were no deaths due to MI. Perioperative MI developed in 8 (3,9%) patients. There were following most significant predictors of perioperative MI: severe impairment of local left ventricular (LV) contractility (hazard ratio (HR), 13,57; 95% confidence interval (CI), 1,427-124,782, p&lt;0,05) and a decrease in left ventricular ejection fraction &lt;50% (HR, 10,909; 95% CI, 1,052-271,229, p&lt;0,05). However, following factors were insignificant for predicting perioperative MI (p&gt;0,05): SYNTAX score, prior cerebrovascular accident, myocardial infarction, insulin-dependent diabetes mellitus, obesity, chronic obstructive pulmonary disease.</p></sec><sec><title>Conclusion</title><p>Conclusion. In high-risk patients with CAD, severe impairment of local LV contractility and global LV systolic dysfunction are the most significant risk factors for perioperative MI during CEA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>факторы кардиального риска</kwd><kwd>каротидная эндартерэктомия</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>фракция выброса левого желудочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac risk factors</kwd><kwd>carotid endarterectomy</kwd><kwd>coronary artery disease</kwd><kwd>left ventricular ejection fraction</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">Акчурин Р.
