Abstract

Prompt reperfusion of acutely ischemic myocardium appears to be the rational way of reversing ischemic injury and limiting the extent of eventual necrosis. Recent advances in emergency coronary bypass surgery, percutaneous transluminal coronary angioplasty (PTCA) and thrombolytic therapy have provided methods for effective treatment of acute myocardial infarction. However, several observations indicate this issue is more complex. Although blood flow must be restored to ischemic myocardium if it is to survive, animal experiments suggest potential deleterious effects associated with this reperfusion. These deleterious effects may be associated with unstable ST segments reported early after acute infarct thrombolysis. Though recurrent coronary occlusion cannot be excluded, reperfusion injury in this setting of coronary artery patency must be considered. This case illustrates this proposed reperfusion injury reflected as "tombstone" ST segment elevation in a patient following successful acute infarct PTCA.
