A case series of OMI: time for revisiting STEMI/NSTEMI ECG criteria

These three cases underscore the diagnostic challenge of identifying occlusive myocardial infarction (OMI) in patients presenting with acute coronary syndrome (ACS) when relying exclusively on traditional STEMI criteria. They emphasize the need to recognize alternative ECG markers indicative of acute coronary occlusion, as failure to do so may result in delayed reperfusion and subsequently worse clinical outcomes compared to patients who receive timely intervention based on prompt STEMI recognition.
