Материал и методы. 145 пациентам с отсутствием сердечно-сосудистой патологии и сахарного диабета выполнялась стресс-эхокардиография с физической нагрузкой на горизонтальном велоэргометре. В состоянии покоя и на пике нагрузки регистрировался коронарный кровоток в средней трети передней межжелудочковой артерии, с помощью допплерографии вычисляли величину коронарного резерва. Группа была разделена на 4 подгруппы по возрастным квартилям. Также проводился анализ распределения величин по полу. Результаты. В покое скорость коронарного кровотока в группе здоровых лиц в срединном сегменте передней межжелудочковой артерии была 31,9 ± 8,3 см/с, скорость на пике нагрузки - 77,4 ± 15,3 см/с, разница скорости на пике и до нагрузки - 45,3 ± 13,4 см/с, значение коронарного резерва - 2,51 ± 0,59. Не было получено значимого влияния возраста на величины скоростей на пике нагрузки и коронарного резерва. У женщин по сравнению с мужчинами была большая скорость кровотока в коронарной артерии в покое, скорость кровотока на пике нагрузки достоверно не отличалась, определялась меньшая величина коронарного резерва (2,32 ± 0,55 против 2,63 ± 0,58; р &lt; 0,02). Выводы. Определены нормальные показатели скоростей коронарного кровотока для здоровых лиц во время физической нагрузки. Данные показатели достоверно не меняются в различных возрастных группах. Женщины имеют меньшие величины коронарного резерва, измеренного с помощью импульсноволнового допплера во время тестов с физической нагрузкой.</p></abstract><trans-abstract xml:lang="en"><p>The aim: to define 1) coronary artery flow velocity values in healthy group at rest and during exercise tests; 2) differences of these values in the different age and sex groups. Materials and methods. There is a single center study of 145 consecutive healthy patients who underwent a bicycle exercise echocardiography with the analysis of coronary artery flow velocity in left anterior coronary artery (LAD). Coronary flow velocities were measured before and at the peak of exercise at the medium segment of the LAD. In addition, the coronary flow velocity reserve (CFVR) was calculated. Results. The rest velocity in LAD was 31.9 ± 8.3 cm/s, at the peak of exercise 77.4 ± 15.3 cm/s, ΔV 45.3 ± 13.4 cm/s, and CFVR 2.51 ± 0.59. There was not a significant difference in the subgroups of the different ages. Women had a lower CFVR in comparison with men (2.32 ± 0.55 vs 2.63 ± 0.58; p &lt; 0.02). Conclusion. There are the values of Doppler coronary artery velocity of the healthy subjects for exercise tests. The study does not demonstrate the impact of aging on CFVR. Women have a lower CFVR during exercise tests.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стресс-эхокардиография</kwd><kwd>визуализация коронарных артерий</kwd><kwd>коронарный резерв</kwd><kwd>эхо-кардиография с физической нагрузкой</kwd><kwd>скорости коронарного кровотока</kwd><kwd>coronary flow reserve</kwd><kwd>exercise echocardiography</kwd><kwd>coronary flow velocity</kwd><kwd>coronary artery visualization</kwd><kwd>stress echocardiography</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">Lowenstein J., Tiano C., Marquez G. et al.
