В наблюдательное исследование вошли пациенты с впервые возникшим ОИМ. В зависимости от ЭКГ-изменений пациенты были разделены на две группы: 1) с подъемом сегмента ST (n = 75) и 2) без подъема сегмента ST (n = 44). Всем пациентам были проведены ЭКГ, анализ биохимических маркеров повреждения миокарда, динамическая однофотонная эмиссионная компьютерная томография миокарда (ОФЭКТ) сердца и перфузионная сцинтиграфия миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. В исследование включили 119 пациентов (возраст – 62,5 ± 10,4 лет, 63% мужчин). Пациенты с подъемом сегмента ST характеризовались более выраженными дефектами перфузии в условиях покоя – 5,00 (3,00; 9,00) и 0,00 (0,00;1,00) и на фоне фармакологического стресс-теста – 7,00 (5,00; 13,00) и 2,50 (0,00;5,00), а также более сниженными стресс-индуцированным миокардиальным кровотоком (МК) – 1,09 (0,83; 1,59) и 1,67 (1,36; 2,46) мл/мин/г, абсолютным – 0,36 (0,01; 0,72) и 1,14 (0,63; 1,72) мл/мин/г и относительным – 1,78 (1,11; 2,19) и 2,57 (2,13; 3,31) миокардиальным резервом (МР) по сравнению с группой без подъема сегмента ST. При корреляционном анализе были выявлены значимые взаимосвязи между стресс-индуцированным МК и креатинфосфокиназой (КФК) через 24 ч и 4 сут: r = –0,34 и r = –0,31, Тропонином I при поступлении и через 24 ч: r = –0,4 и r = –0,3; относительным и абсолютным резервом МК с Тропонином I при поступлении: r = –0,41 и r = –0,41.</p></sec><sec><title>Заключение</title><p>Заключение. Количественные показатели миокардиальной перфузии, определенные с помощью ранней динамической ОФЭКТ миокарда, ассоциированы с ЭКГ-изменениями и биохимическими маркерами повреждения миокарда и позволяют адекватно оценить тяжесть течения заболевания у пациентов с перенесенным ОИМ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: To study the relationship of microcirculatory changes in coronary bed and electrocardiographic and laboratory signs of damage to myocardium in patients with acute myocardial infarction (AMI).</p></sec><sec><title>Methods</title><p>Methods. The observational study included patients with newly emerged AMI. Depending on the ECG changes, the patients were divided into two groups: 1) with ST segment elevation (n = 75) (STEMI) and 2) without ST segment elevation (n = 44) (NSTEMI). All patients underwent electrocardiography, analysis of biochemical markers of myocardial damage, dynamic single photon emission computed tomography (SPECT) and myocardial perfusion imaging.</p></sec><sec><title>Results</title><p>Results. The study included 119 patients (age 62.5 ± 10.4 years, 63% men). STEMI patients had heavier perfusion defects at rest, 5.00 (3.00;9.00) and 0.00 (0.00;1.00), and after pharmacological stress test, 7.00 (5.00;13.00) and 2.50 (0.00;5.00), also they had more reduced stress myocardial blood flow (MBF), 1.09 (0.83;1.59) and 1.67 (1.36;2.46) ml/min/g, flow difference (FD), 0.36 (0.01;0.72) and 1.14 (0.63;1.72) ml/min/g, and myocardial flow reserve (MFR), 1.78 (1.11;2.19) and 2.57 (2.13;3.31), according to compared to NSTEMI patients. Correlation analysis revealed significant relationships between stress MBF and CPK after 24 hours and 4 days: r = –0.34 and r = = –0.31, troponin I upon admission and after 24 hours – r = –0.4 and r = –0.3; MFR and FD and troponin I upon admission – r = –0.41 and r = –0.41.</p></sec><sec><title>Conclusion</title><p>Conclusion. Quantitative parameters of myocardial perfusion determined by early dynamic myocardial SPECT are associated with electrocardiographic changes and biochemical markers of myocardial damage and allow an adequate assessment of the severity of the disease in patients with AMI.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острый инфаркт миокарда</kwd><kwd>динамическая однофотонная эмиссионная компьютерная томография</kwd><kwd>перфузионная сцинтиграфия миокарда</kwd><kwd>миокардиальный кровоток</kwd><kwd>миокардиальный резерв</kwd><kwd>повреждение миокарда</kwd><kwd>коронарная микрососудистая дисфункция</kwd><kwd>инфаркт миокарда с подъемом сегмента ST</kwd><kwd>инфаркт миокарда без подъема сегмента ST</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute myocardial infarction</kwd><kwd>dynamic single-photon emission computed tomography</kwd><kwd>myocardial perfusion imaging</kwd><kwd>myocardial blood flow</kwd><kwd>myocardial flow reserve</kwd><kwd>myocardial damage</kwd><kwd>coronary microvascular dysfunction</kwd><kwd>ST-elevation myocardial infarction</kwd><kwd>non-ST-elevation myocardial infarction</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">Knuuti J., Wijns W., Saraste A., Capodanno D., Barbato E., Funck-Brentano C. et al.
