However, data of the prognostic value obtained from a complex analysis of contractility disorders and coronary blood flow parameters during exercise tests in the world literature are still not available. Aim. To develop risk models for adverse outcomes in patients with probable or definite IHD based on the results of a stress test with a noninvasive coronary blood flow study. Material and methods. Medical data of 689 patients with probable or definite IHD who underwent stress echocardiography with satisfactory visualization of the anterior interventricular artery (AIVA) were included in the analysis. All patients had stress echocardiography on a horizontal bicycle ergometer. Registration of coronary blood flow in the middle third of the AIVA was performed at rest and at the peak of the load with calculation of the coronary reserve value. Further patient follow-up lasted 3 years. Models of further negative outcomes were developed on the basis of the stress echocardiography results and of coronary blood flow parameters. Results. Three models that take into account the factors associated with further mortality, mortality/myocardial infarction and sum of negative outcomes were developed in the study. These models divide a cohort of patients with probable or definite IHD into groups of low, medium and very high risks. Factors associated with the risk of death include: age &gt;56 years, load power &lt;100 W, breach of contractility in the blood supply zone of the circumflex artery initially and during exercise, the difference in blood flow velocities in the AIVA&lt;10 cm/s, coronary reserve of AIVA&lt;2. The risk model of death, taking into account these factors, suggests dividing patients into low-risk group if there are ≤2 factors (mortality 0.6% for 3 years), medium risk – from 2 to 4 factors (mortality 1.8%), high risk – ≥5 factors (mortality 10.3% for 3 years). Conclusion. The study of coronary blood flow during stress echocardiography in addition to the analysis of left ventricular contractility in patients with probable or definite IHD contributes to determine the prognosis of further negative outcomes.</p></abstract><trans-abstract xml:lang="ru"><p>Развитие ультразвуковых методов неинвазивной визуализации коронарных артерий позволяет проводить точную диагностику ишемической болезни сердца (ИБС) в обычной клинической практике. Однако в мировой литературе до сих пор отсутствуют данные прогностического значения, полученные из комплексного анализа нарушений сократимости и параметров коронарного кровотока во время тестов с физической нагрузкой. Цель. Создать модели риска неблагоприятных исходов у пациентов с установленной или предполагаемой ИБС на основе параметров теста с физической нагрузкой с неинвазивным исследованием коронарного кровотока. Материал и методы. В анализ включены данные 689 человек, направленных на стресс-эхокардиографический тест с физической нагрузкой с диагностированной или предполагаемой ИБС с удовлетворительной визуализацией передней межжелудочковой артерии (ПМЖА) во время стресс-эхокардиографии. Всем пациентам выполнялась стресс-эхокардиография на горизонтальном велоэргометре. В состоянии покоя и на пике нагрузки регистрировался коронарный кровоток в средней трети ПМЖА; с помощью допплерографии вычисляли величину коронарного резерва. В течение трех лет проводилось наблюдение за пациентами. На основе данных стресс-эхокардиографии с параметрами коронарного кровотока были созданы модели дальнейших неблагоприятных исходов. Результаты. В исследовании созданы три модели, учитывающие факторы, связанные с дальнейшей смертностью, смертностью/инфарктом миокарда, с суммой неблагоприятных исходов. Данные модели делят когорту пациентов с предполагаемой или диагностированной ИБС на группы низкого, среднего и крайне высокого рисков. Факторами, связанными с риском смерти, явились: возраст &gt;56 лет, мощность нагрузки &lt;100 Вт, наличие нарушений сократимости в зоне кровоснабжения огибающей артерии исходно и во время нагрузки, разница скоростей кровотока в ПМЖА&lt;10 см/с, коронарный резерв ПМЖА&lt;2. Модель риска смерти, учитывающая эти факторы, предполагает деление пациентов на группу низкого риска при наличии не более 2 факторов – смертность 0,6% за 3 года, среднего риска – от 2 до 4 факторов – смертность 1,8%, высокого риска от 5 и более факторов – смертность 10,3% в течение 3 лет. Заключение. У пациентов с предполагаемой или диагностированной ИБС исследование коронарного кровотока во время стресс-эхокардиографии в дополнение к анализу сократимости левого желудочка способствует определению прогноза дальнейших неблагоприятных исходов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стресс-эхокардиография</kwd><kwd>визуализация коронарных артерий</kwd><kwd>коронарный резерв</kwd><kwd>эхокардиография с физической нагрузкой</kwd><kwd>скорости коронарного кровотока</kwd><kwd>математическая модель риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress echocardiography</kwd><kwd>coronary artery imaging</kwd><kwd>coronary reserve</kwd><kwd>echocardiography stress test</kwd><kwd>coronary blood flow velocity</kwd><kwd>mathematical risk model</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">Boshchenko A.A., Vrublevskiy A.V.
