Concerning history, known CAD" Recorded 2 hours after pain onset: What do you think? The patient was diagnosed with a"Non-STEMI." Traditionally , Occlusion MI (OMI) myocardial infarctions that are not STEMI are called NonSTEMI. This was my response: "This looks like a worrisome EKG. But by now you must have a repeat ECG.

This is a troponin I level that is almost exclusively seen in STEMI. A followup ECG was recorded 2 days later: No definite evidence of infarction. So this is either a case of MINOCA, or a case of Type II STEMI. I believe the latter (type II STEMI) is most likely. pulmonary embolism, sepsis, etc.), myocarditis).

He had no previous history of CAD, and presented with very typical waxing and waning chest pain, much worse with exertion but also present at rest and on presentation, though his pain was minimal at the time of the ECG. This is all suggestive of posterior STEMI, but not definitely diagnostic. Blood pressure was 150/80.

The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. Is that an obvious STEMI underneath that rhythm? But this is not definite because the angiogram was not done at the same time as the ECG changes suggesting OMI.

These findings are very subtle but suspicious for LAD occlusion, as we have seen in many similar (but less difficult) cases on this blog: A man in his sixties with chest pain at midnight with undetectable troponin How long would you like to wait for your Occlusion MI to show a STEMI? He also had non-acute CAD of the RCA (50%) and LCX (50%).
