Yes, ST DEP goes with SUBendocardial infarct. I think it has something to do with the location of the infarct and the ECG lead placement. Have to look up.

This is either UA or NSTEMI (non ST-segment elevation MI)
They can not be distinguishable at initial evaluation but since the CK-MB was increased over the following 48 hours then it should be NSTEMI Now why is this considered subendocardial? Maybe because the thrombus of UA/NSTEMI is small and only partially occlusive, it usually sheds small emboli that occlude small intramyocardial arteries and cause micro infarctions that are responsible for the elevation in CK-MB. and since the smallest arteries are in the subendocardium well this is where the infarction is going to be. Stupid question in my opinion

Not a stupid question, since we are discussing the explanation, hence, enhancing our knowledge
 And on that note, thank you for your explanation.
