I sent this to the Queen of Hearts So the ECG is both STEMI negative and has no subtle diagnostic signs of occlusion. Non-STEMI guidelines call for “urgent/immediate invasive strategy is indicated in patients with NSTE-ACS who have refractory angina or hemodynamic or electrical instability,” regardless of ECG findings.[1]

So this NSTEMI was likely a STEMI(-)OMI with delayed reperfusion. The patient was admitted as ‘NSTEMI’ which is supposed to represent a non-occlusive MI, but the underlying pathophysiology is analogous to a transient STEMI. West J Emerg Med 2024). Fortunately the patient did not reocclude while awaiting the angiogram.

While STEMI negative, the ECG is diagnostic of proximal LAD occlusion. Transient STEMI” are often managed like non-STEMI with delayed angiography, which is very risky. This case is an example of the steps we can all take in daily practice as the paradigm shifts from STEMI to OMI.

This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI.

If we took this as the gold standard, we would conclude that the computer interpretation was safe and accurate at least accurate enough to not miss STEMI, and that physicians should not be interrupted to interpret it, because there would be no change in patient management. What is the gold standard for ECG interpretation: patient outcome!!!

Its hard to measure the STE in I exactly with the moving baseline, but there is almost certainly not enough STE to meet STEMI criteria. The ACC recognizes these findings as formal STEMI equivalents (though they do not define how to find them). They are symmetric, fat, convex on both sides, etc. 13 post.

Prompt cath is therefore advised if the post-ROSC shows an acute STEMI. To Emphasize: The phenomenon of T-QRS-D is not needed in today's case to recognize the acute STEMI. The decision of whether to cath patients with a less definitive post-ROSC ECG is less clear.

This was a machine read STEMI positive OMI.

This is documented as a STEMI in the clinical notes and in the cath report, but certainly does not meet STEMI criteria and is therefore an NSTEMI by definition. For national registry purposes, this will be incorrectly classified as a STEMI.) Most STEMI have peak cTnI greater than 10.0. Large STEMI are approximately 30-80.
