Анализ деформации миокарда в режиме Strain и Strain Rate при стресс-эхокардиографии с добутамином в зависимости от степени стеноза коронарных артерий

2008 
Possibilities of clinical using of the Strain and Strain Rate regimens in the diagnosis of hemodynamically valuable coronary artery sclerosis during the test with dobutamin in patients with no signs of disturbed left ventricular local contractility at rest were investigated in the study. We analyzed sensitivity, specificity and prognostic value of the Strain in the topic diagnosis of coronary artery strenosing atherosclerosis. The most sensitive is this marker for anterior descending branch of the left coronary artery, the least sensitive is this marker for circumflex artery. The given study results confirmed influence of coronary circulation on left ventricular segmental contractility indices.
