OBJECTIVE To evaluate whether the presence of viable myocardium, detected by low dose dobutamine echocardiography, limits the likelihood of left ventricular dilatation in patients with acute myocardial infarction. PATIENTS 107 patients were studied by low dose dobutamine echocardiography at (mean (SD)) 3 (1) days after acute myocardial infarction. Cross sectional echocardiography was repeated...

OBJECTIVES The aim of the study was to assess the prognostic value of myocardial viability and ischemia detected by dobutamine stress echocardiography (DSE) in patients with acute myocardial infarction (AMI) treated with thrombolysis. BACKGROUND DSE can detect myocardial viability and ischemia early after AMI, but the prognostic importance of viability and ischemia in these patients has yet t...

It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...

Assessment of myocardial viability is of ever-evolving interest in cardiovascular imaging, with major societies having incorporated viability imaging as class I or class IIa indications in their guidelines to better guide patient management. As with late gadolinium enhancement cardiac magnetic resonance (MR), assessment of residual myocardial viability or the extent of myocardial infarction is ...

the aim of this article is to review the application of current imaging techniques used for the detection of viable myocardium. each technique is discussed briefly, and the more commonly used techniques are compared. the imaging techniques reviewed herein are dobutamine stress echocardiography, single photon emission tomography, magnetic resonance imaging, positron emission tomography with f-18...
