"Non-STEMI" is a worthless term.

Dr. Smith's ECG Blog

A 60 yo with 2 previous inferior (RCA) STEMIs, stented, called 911 for one hour of chest pain. Here is his most recent previous ECG: This was recorded after intervention for inferior STEMI (with massive ST Elevation, see below), and shows inferior Q-waves with T-wave inversion typical of completed inferior OMI. ng/mL (quite large).

Chest pain and a computer ‘normal’ ECG. Therefore, there is no need for a physician to look at this ECG.

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. Deutch et al. Fortunately the patient did not reocclude while awaiting the angiogram.

Another myocardial wall is sacrificed at the altar of the STEMI/NonSTEMI mass delusion (and Opiate pain relief).

Cath lab declined as it is not a STEMI." And now this finding is even formally endorsed as a "STEMI equivalent" in the 2022 ACC guidelines!!! Another myocardial wall is sacrificed at the altar of the STEMI/NonSTEMI mindset. de Winter et al in N Engl J Med 359:2071-2073, 2008. Cath attending is aware. Abstract 556.

OMI-NOMI paradigm established as better than STEMI-NSTEMI with new article

Dr. Smith's ECG Blog

Their OMI Manifesto details how use of standard STEMI criteria results in an unacceptable level of inaccuracy, in which an estimated 25-30% of acute coronary occlusions are missed! The article by Aslanger, Smith et al that is featured above in today’s post has just been published.

EMS 12-Lead

Figure 1-1 My colleague, a faithful student of ECG interpretation, handed me the tracing and said that it warranted STEMI activation because of apparent terminal QRS distortion (TQRSD) in V2. 1, 2] The most clinically useful definition to account for this entire constellation is intraventricular conduction delay.

Doctor, should we activate the hospital's "STEMI alert"?

Dr. Smith's ECG Blog

They wanted to know if I would like them to activate the outside hospital's "STEMI alert." But of course, this is not a STEMI by definition as it does not meet STEMI criteria. They shot this ECG right before going into the ED: Clearly meets STEMI criteria with large STE in V2-V5. Here is the ECG: What do you think?

What does the angiogram show? The Echo? The CT coronary angiogram? How do you explain this?

Dr. Smith's ECG Blog

Lindahl et al. From Gue at al. STEMI MINOCA versus NSTEMI MINOCA STEMI occurs in the presence of transmural ischaemia due to transient or persistent complete occlusion of the infarct-related coronary artery. This has resulted in an under-representation of STEMI MINOCA patients in the literature.
