DE's low NPV risks missing viable myocardium; leaves open whether PET should guide revascularization decisions in ischemic HF.
Does PET or dobutamine echocardiography better predict functional recovery of hibernating myocardium in patients with postischaemic heart failure undergoing CABG?
PET has a significantly higher negative predictive value than dobutamine echocardiography for identifying recoverable LV dysfunction in patients with severe postischaemic heart failure.
Pagano et al. (1998) studied this question.
