Predictive accuracy of echocardiographic response of mildly dyssynergic myocardial segments to low-dose dobutamine.
Low-dose dobutamine echocardiography has a high sensitivity for predicting functional recovery after revascularization. In segments with mild wall motion abnormalities, the specificity of the technique is rather low, suggesting overestimation of functional recovery in these segments.
