Оценить возможности стресс-ЭхоКГ в позиции на корточках для диагностики ишемической болезни сердца. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 53 мужчины (средний воз раст – 53,2±0,93 года), направленных для проведения стресс-эхокардиографии. По результатам коронароангиографии диагноз ишемической болезни сердца был верифицирован у 37 мужчин (средний возраст – 54,1±1,2 года), вторую группу составили 16 мужчин (средний возраст – 51,0±1,4 года) без ишемии. Всем пациентам по стандартной методике проводилась стресс-эхокардиография с добутамином, а также была проведена эхокардиография в положении на спине и в положении на корточках; критериями ишемии считалось появление дополнительных зон асинергии миокарда левого желудочка.</p></sec><sec><title>Результаты</title><p>Результаты. Проба была выполнена у всех пациентов, осложнений выявлено не было. Нарушения локальной сократимости появлялись во время приседания на корточки и быстро исчезали при вставании. В выявлении ишемической болезни сердца чувствительность пробы “на корточках” составила 94,6%, специфичность – 81,3%. </p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, нами выявлена высокая диагностическая ценность стресс-эхокардиографии в позиции на корточках для диагностики ишемии, не уступающая стресс-эхокардиографии с добутамином.</p></sec></abstract><trans-abstract xml:lang="en"><p>While stress echocardiography (EchoCG) is widely used in clinical practice for diagnosing silent myocardial ischemia, the search for new stress tests remains an important task in the diagnostics of coronary heart disease (CHD). </p><sec><title>Aim</title><p>Aim.

In total, 53 men (mean age 53,2±0,93 years) underwent stress EchoCG. At coronary angiography, the CHD diagnosis was verified in 37 men (mean age 54,1±1,2 years), while in the other 16 men (mean age 51,0±1,4 years), myocardial ischemia was not confirmed. All participants underwent standard stress EchoCG with dobutamine, as well as supine and squatting EchoCG. The myocardial ischemia criterion was the development of additional asynergy zones in left ventricular myocardium. </p></sec><sec><title>Results</title><p>Results. The test was performed in all patients, without any complications. Disturbed local contractility was observed at the time of squatting and rapidly disappeared while standing up. The sensitivity and specificity of squatting stress EchoCG in the CHD diagnostics were 94,6% and 81.3%, respectively. </p></sec><sec><title>Conclusion</title><p>Conclusion. Therefore, we have demonstrated a high diagnostic value of squatting stress EchoCG for diagnosing myocardial ischemia. This value was comparable to that of stress EchoCG with dobutamine.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>стресс-эхокардиография: нагрузочная проба в позиции на корточках</kwd><kwd>продольная деформация миокарда ЛЖ</kwd><kwd>максимальный систолический стрейн</kwd><kwd>коронароангиография</kwd><kwd>локальная сократимость миокарда ЛЖ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stress echocardiography</kwd><kwd>squatting stress test</kwd><kwd>left ventricular longitudinal myocardial deformation</kwd><kwd>peak systolic strain</kwd><kwd>coronary angiography</kwd><kwd>left ventricular local contractility</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">Clinical guidelines for ultrasound diagnostics.
