Определение основных дифференциально-диагностических признаков кардиомегалии ишемической и некоронарогенной природы. Материал и методы. Обследовано 50 пациентов с кардиомегалией: у 32 человек кардиомегалия сформировалась вследствие ишемической болезни сердца (ИБС) - кардиомегалия ишемической природы (ИКМ), группу некоронарогенной кардиомегалии (НКМ) составили 18 больных. Перфузия и метаболизм миокарда оценивались методом позитронной эмиссионной томографии (ПЭТ) с13N-аммонием и18F-фтордезоксиглюкозой. Результаты. У всех пациентов с ИКМ установлены участки выраженной гипоперфузии, локализованные более чем в 3 близлежащих сегментах, в строгом соответствии с бассейнами стенозированных коронарных артерий. С высокой частотой наблюдались стресс-индуцированные дефекты перфузии. У всех пациентов этой группы с равной частотой обнаружены согласованные дефекты перфузии и метаболизма, соответствующие зонам постинфарктного кардиосклероза и несогласованные  дефекты, характерные для гибернирующего миокарда. У пациентов с НКМ установлен преимущественно диффузный характер нарушения коронарной микроциркуляции. Несогласованные дефекты у пациентов этой группы не обнаружены. Выводы. Диффузный характер нарушения перфузии и метаболизма миокарда левого желудочка, а также отсутствие несогласованных дефектов являются основными отличительными чертами кардиомегалии некоронарогенной природы от ИБС.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The study addresses differentiation of ischemic and non-ischemic cardiomegaly by positron emission tomography (PET). Design and methods. Based on echocardiography data 50 patients with cardiomegaly and reduced systolic function were included in the study: 32 patients with coronary heart disease (CHD) and 18 patients with normal coronary arteries according to angiography results (6 of them had alcohol abuse). All patients underwent PET with [13N]-ammonia and [18F]-FDG for myocardial perfusion and metabolism evaluation. A semiquantitative analysis of the images was performed. Results. All patients with CHD showed large hypoperfusion areas (more than 3 segments) matching the coronary artery flow. Perfusion/metabolism match was revealed in all (100 %) patients with CHD and perfusion/metabolism mismatch was observed in 25 (79 %) patients of the same group. The patients with noncoronarogenic cardiomegaly (NCM) had diffuse heterogeneity of myocardial perfusion, 5 of them showed small and mild perfusion defects with non-segmental distribution. The areas of abnormal perfusion were significantly larger in cases of CHD. Perfusion/metabolism match was noted in 2 (11 %) patients with NCM and none of the patients with NCM showed perfusion/metabolism mismatch. Conclusion. Diffuse heterogeneity of myocardial perfusion, non-segmental distribution of perfusion defects and lack of perfusion/metabolism mismatch are the most important features of noncoronarogenic cardiomegaly as compared to ischemic cardiomegaly.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>позитронная эмиссионная томография</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>кардиомегалия некоронарогенной природы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac positron emission tomography</kwd><kwd>coronary heart disease</kwd><kwd>noncoronarogenic cardiomegaly</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">Le T., Ko J.Y., Kim H.T. et al.
