Diagnostic potentials of stress-echocardiography and tissue doppler sonography when determining myocardium viability and evaluating longitudinal function of the left ventricle in ischemic heart disease patients with evident LV dysfunction

Studying myocardium viability in ischemic heart disease (IHD) patients with severe left ventricle dysfunction is of great importance in determining the tactics of patient management and surgery treatment prognosis. At present a quantitative assessment of longitudinal systolic and diastolic function of a viable myocardium is limited. The purpose of this study is to determine diagnostic potentials of stress-echocardiography (SEC) with the use of tissue Doppler sonography in determining a viable myocardium and evaluating longitudinal function of the left ventricle (LV) in IHD patients with evident LV dysfunction after surgical treatment.
