Материал и методы. В покое и на фоне фармакологической нагрузки 16 пациентам с ишемической болезнью сердца (ИБС) и 9 здоровым добровольцам была проведена динамическая однофотонная эмиссионная компьютерная томография (ОФЭКТ) сердца с 99mТс-Технетрилом. В процессе обработки полученных результатов формировали зоны интереса с полости и стенок миокарда левого желудочка (ЛЖ), на основании которых строили кривые “активность–время”. Индекс резерва миокардиального кровотока определялся как частное двух отношений среднего значения счета импульсов с области миокарда к площади под пиком кривой с полости ЛЖ для исследования на фоне нагрузки и в условиях покоя. Результаты. Среднее значение показателя миокардиального резерва в группе здоровых добровольцев составило 1,86 (1,59; 2,2), у лиц с атеросклерозом коронарных артерий – 1,39 (1,12; 1,69). Значение индекса резерва миокардиального кровотока, полученное при выполнении динамической ОФЭКТ сердца, менее 1,77 позволяет идентифицировать трехсосудистое поражение коронарных артерий с чувствительностью и специфичностью 81,8 и 66,7% соответственно. Рассмотренная методика является перспективным направлением, требующим дальнейшей клинической валидизации.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to develop the methodology for collecting and processing the scintigraphic data to determine myocardial reserve on gamma camera with a solid state cadmium zinc tellurium detectors. Sixteen patients with coronary artery disease and 9 healthy volunteers underwent dynamic cardiac SPECT with 99mTc(MIBI at rest and at pharmacological stress(test. The processing of the results included construction of the “activity–time” curves based on the identification of regions of interest in the cavity and the walls of the left ventricular (LV) myocardium. Myocardial blood flow reserve index was determined as a quotient of two ratios of mean values of counts from the myocardial area to the area under the LV cavity curve obtained in stress test and at rest. According to our data, mean value of myocardial blood flow reserve was 1.86 (1.59; 2.2) in group of healthy volunteers and 1.39 (1.12; 1.69) in patients with coronary artery disease. Cardiac dynamic SPECT(based value of myocardial blood flow reserve index &lt;1.77 allows for identification of three-vessel coronary artery disease with sensitivity and specificity of 81.8 and 66.7%, respectively. Thus, we believe that the development of a methodology for the assessment of myocardial blood flow reserve by SPECT is a promising direction requiring further study and verification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миокардиальный резерв</kwd><kwd>однофотонная эмиссионная компьютерная томография</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>позитронная эмиссионная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardial flow reserve</kwd><kwd>single photon emission computer tomography</kwd><kwd>coronary artery disease</kwd><kwd>positronemission tomography</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">Ben(Haim S., Murthy V.L., Breault С. et al.
