Dobutamine echocardiography is the most useful technique for predicting improvement of LV function after CABG

Pooled data demonstrate that improvement in regional left ventricular (LV) function is best predicted by dobutamine echocardiography which had positive and negative predictive accuracies of 83 and 81 percent, respectively, and positron emission tomography (PET) with enhanced fluorodexyglucose (FDG) uptake relative to myocardial blood flow (MBF) which had positive and negative predictive accuracies of 82 and 83 percent, respectively. By contrast, the postive and negative predictive accuracies with thallium single-photon emission computed tomography (SPECT) are 69 and 90 percent, respectively.
