title: Repeated 99mTc-Sestamibi studies for the evaluation of salvaged myocardium and of its relationship with postinfarction ischemia.
abstract: Pre- and post-treatment myocardial scans with 99mTc-Sestamibi demonstrated effective reperfusion after thrombolysis in a patient with acute myocardial infarction. Late follow-up images showed at rest a further noteworthy reduction of the uptake defect and that during exercise a large part of the salvaged territory became ischemic. This report demonstrates that a remarkable amount of myocardium in the posttreatment images was hibernated; furthermore, it was possible to visualize directly that the salvaged territory is the actual site of exercise induced postinfarction ischemia.
