Although PPCI results in reduction in both mortality and morbidity compared with thrombolytic therapy, ischemia/reperfusion (I/R) injury remains an important complica-tion, contributing up to 50% of final infarct size (1).

ST Elevation MI (STEMI) infarction patterns will be discussed for the patient experiencing acute injury to the inferior, anterior, and lateral surfaces of the heart. Non-ST elevation myocardial infarction (Non-STEMI) patterns and treatments will also be discussed.

      myocardial ischemia and injury are basic to this expertise. The EKG may be normal, abnormal with subtle findings, or grossly abnormal in the pres- ence of acute myocardial infarction. In the emergent evaluation, two find- ings are of interest: myocardial injury pattern and LBBB. Patients with
