CAD-RADS category 1. --No At this point, with the information above, the patient's overall clinical picture could be consistent with either reperfused OMI, or Non-OMI, since both may have absent pain and inverted T waves. A repeat troponin returned at 0.45 ng/mL, consistent with reperfused OMI, or Non-OMI. A CT Coronary angiogram was ordered.

This case represents the same physiologic event as OMI in terms of the result on the myocardium, therefore with identical ECG features, however there may not be ACS!
