This study investigated the relative and combined utility of delayed enhancement (DE) CMR and low dose dobutamine (LDD) CMR for the prediction of both infarct zone and global left ventricular functional recovery following myocardial infarction. Adding LDD to DE CMR required an additional fifteen minutes and significantly improved prediction of functional recovery. A comprehensive CMR examination with both DE and LDD allowed more accurate prediction of both infarct zone and global functional recovery than either component alone.
