ASSESSMENT OF PATIENTS AFTER CORONARY-ARTERY BYPASS-GRAFTING BY DOBUTAMINE STRESS ECHOCARDIOGRAPHY

Detection of myocardial ischemia is the hallmark of noninvasive evalua tion of graft function(1-5) after coronary artery bypass grafting (CAB G). Exercise electrocardiography was shown to have a limited accuracy in this clinical setting.(3) Recent studies have demonstrated a high a ccuracy of exercise echocardiography for the detection of significant graft or progressive native coronary artery stenosis.(3-5) However, an alternative stress modality is required for patients with limited exe rcise capacity.
