Early Dipyridamole ^99m Tc-Sestamibi Single Photon Emission Computed Tomographic Imaging 2 to 4 Days After Acute Myocardial Infarction Predicts In-Hospital and Postdischarge Cardiac Events

Abstract

Dipyridamole MPI very early after MI predicts early and late cardiac events, with superior prognostic value compared with submaximal exercise imaging. The extent and severity of the stress defect and reversibility of the defect were the most important predictors of cardiac death and recurrent MI. This technique can allow management decisions to be made earlier with regard to AMI patients and could have important economic impact if applied widely.
