Dobutamine stress echocardiography for assessment of hibernating myocardium
Journal of Myocardial Ischemia
It is now well recognized that akinetic or severely hypokinetic segments of the left ventricle may be composed of viable myocardium. Revascularization of this tissue is associated with improved contractile function. Distinction between hibernating myocardium and irreversibly damaged scar tissue is therefore of obvious clinical importance. A variety of invasive and noninvasive techniques have been employed in making this distinction. Recently, dobutamine stress echocardiography has been proposed as a safe, relatively inexpensive, and reliable test for identifying dysfunctional but viable myocardium.
