Материалы и методы. В исследование были включены 17 больных, каждому из которых проводили селективную коронароангиографию (КАГ) и синхронизированную с ЭКГ С-ОФЭКТ/КТ миокарда с 99mTc-технетрилом в покое и в сочетании с пробой с физической нагрузкой на велоэргометре (ВЭМ-пробой). Верификацию ишемии и оценку ДФ проводили с помощью С-ОЭКТ/КТ c 99mTc-технетрилом в покое (r) и с ВЭМ-пробой (s) по 2-дневному протоколу. Количественные показатели перфузии (КПП) и ДФ оценивали по 17 сегментарной модели ЛЖ: rExtent/sExtent, площадь нарушения перфузии (НП); SRS, SSS, тяжесть НП; rTPD/sTPD, общий дефицит перфузии; SDS, показатель стресс-индуцированной (обратимой) ишемии; iTPD, ишемический дефицит перфузии; PFR, пиковая объемная скорость наполнения ЛЖ; MFR/3, средняя скорость наполнения ЛЖ в первую/3 диастолы; TTPF, время от начала диастолы до пикового уровня наполнения ЛЖ; PFR2, пиковая объемная скорость наполнения ЛЖ во время 2-го пика. Результаты. У обследованных больных с МСС с подтвержденной ишемией миокарда методом С-ОФЭКТ/КТ выявляются признаки нарушений перфузии миокарда и диастолической дисфункции (ДДФ), о чем свидетельствует отклонение от нормальных значений количественных показателей (КП), характеризующих ДФ ЛЖ. При сопоставлении КП перфузии и ДФ миокарда ЛЖ выявлена прямая связь между распространенностью и выраженностью нарушений перфузии в покое и стресс-индуцированной ишемией и временными характеристиками и обратная - со скоростными показателями диастолы. Заключение. У больных с МСС с верифицированной преходящей ишемией миокарда выявляются признаки ДДФ ЛЖ. Проведенный корреляционный анализ показал наличие взаимосвязи между нарушениями перфузии и ДФ ЛЖ.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To study the correlation between quantitative perfusion parameters and the diastolic function in patients with microvascular angina according to the single-photon emission computed tomography with 99mTc. Material and methods. The study included 17 patients, each of whom underwent selective coronary angiography (CAG) and ECG-synchronized C-SPECT/CT of myocardium with 99mTc-technetril at rest and in combination with exercise testing on bicycle ergometer (ergonometer Anaerobic Test). Verification of ischemia was performed using C-SPECT/CT with 99mTc-technetril at rest (r) and with ergonometer Anaerobic Test (s) according to a 2-day protocol. Quantitative perfusion indices (QPI) and DF were assessed by 17 segmental LV model: rExtent/sExtent, area of perfusion impairment (PI); SRS, SSS, severity of NP; rTPD/sTPD, total perfusion deficit; SDS, stress-induced (reversible) ischemia index; iTPD, ischemic perfusion deficit; PFR, peak LV volume filling rate; MFR/3, avg. LV filling rate in the first/3 of diastole; TTPF, time from the beginning of diastole to the peak LV filling level; PFR2, peak LV filling volume rate during the 2nd peak. Results. The present study revealed a diastolic dysfunction in patients with microvascular angina and increased diastolic filling disturbances during myocardial ischemia with exercise. When comparing the perfusion and diastolic function, a direct link between the prevalence and the intensity of perfusion dysfunction at rest and stress-induced ischemia and temporary parameters and inverse correlation - with speed parameters of diastole was revealed. Conclusion. Patients with microvascular angina show signs of left ventricular dysfunction. The conducted correlational analysis revealed the existence of interconnection between perfusion and diastolic function.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрососудистая стенокардия</kwd><kwd>микрососудистая дисфункция</kwd><kwd>диастолическая дисфункция</kwd><kwd>перфузия миокарда</kwd><kwd>синхронизированная с ЭКГ однофотонная эмиссионная компьютерная томография миокарда</kwd><kwd>совмещенная с рентгеновской компьютерной томографией (С-ОФЭКТ/КТ)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microvascular angina</kwd><kwd>microvascular dysfunction</kwd><kwd>diastolic dysfunction</kwd><kwd>myocardial perfusion</kwd><kwd>single photon emission computed 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">Cannon R.O.
