The ECG did not meet STEMI criteria, and the final cardiology interpretation was “ST and T wave abnormality, consider anterior ischemia”. There’s only minimal ST elevation in III, which does not meet STEMI criteria of 1mm in two contiguous leads. But STEMI criteria is only 43% sensitive for OMI.[1]

Important point: when there is diffuse subendocardial ischemia but no OMI, a wall motion abnormality will not necessarily be present. They agreed ischemia was likely in the setting of demand given DKA and infection. That this is all demand ischemia is unlikely. Lung exam showed diffuse B lines bilaterally. Aslanger's pattern.

4,5] We have now formally studied this question: Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review.[6] have published a number of warnings about the previous reassuring studies.[4,5]

This suggests further severe ischemia. 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. From Gue at al.

Step 1 to missing posterior MI is relying on the STEMI criteria. A prospective validation of STEMI criteria based on the first ED ECG found it was only 21% sensitive for Occlusion MI, and disproportionately missed inferoposterior OMI.[1] But it is still STEMI negative. A 15 lead ECG was done (below). In a study last year, 14.4%

Subendocardial Ischemia from another Cause ( ie, sustained tachyarrhythmia; cardiac arrest; shock or profound hypotension; GI bleeding; anemia; "sick patient" , etc. ). To EMPHASIZE: This pattern of diffuse Subendocardial Ischemia does not suggest acute coronary occlusion ( ie, it is not the pattern of an acute MI ).

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( The below ECG was recorded.
