A Non-ST Elevation Myocardial Infarction (NSTEMI) is distinguished by an elevation of cardiac enzymes without the characteristic ST-elevation seen on EKG. Due to insufficient diagnostic evidence at clinical presentation, there is a need for additional diagnostic tests. Thus myocardial perfusion imaging aids in complementing the diagnostic and therapeutic approach of these patients. A 52-year-old woman presented acute chest pain in the Nuclear Cardiology waiting room. An EKG showed no changes in the ST segment. A myocardial perfusion study showed moderate to severe perfusion defects in the territories of the anterior descending, right and circumflex arteries. This evaluation was later confirmed by coronary angiography, demonstrating the need for further evaluation of perfusion in these patients.
