20% of cases that everyone would call a STEMI have a competely open artery by the time of angiogram 60-90 minutes later. Patient stated that he has had glucose over 400 even though he has not missed any doses of insulin. Here is the ECG at that point in time: The ischemia is mostly resolved.

A man in his 70s with past medical history of hypertension, dyslipidemia, CAD s/p left circumflex stent 2 years prior presented to the ED with worsening intermittent exertional chest pain relieved by rest. Written by Nathanael Franks MD, reviewed by Meyers, Smith, Grauer, etc. In my opinion, I think it looks more like subendocardial ischemia.

A prior ECG from 1 month ago was available: The presentation ECG was interpreted as STEMI and the patient was transferred emergently to the nearest PCI center. The patient proceeded to cath where all coronaries were described as normal with no evidence of any CAD, spasm, or any other abnormality. So maybe she is better than I am.

This is technically a STEMI, with 1.5 However, I think many practitioners might not see this as a clear STEMI, and would instead call this "borderline." They collected several repeat ECGs at the outside hospital before transport: None of these three ECGs meet STEMI criteria. This ECG was recorded on arrival: What do you think?

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%).

2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab. She has not had a heart catheterization or after this event so the presence or absence of CAD is still unknown.

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. 2 The astute paramedic recognized this possibility and announced a CODE STEMI. 6,7 Surgical repair of AS, by either TAVR or SAVR, is the definitive treatment for this condition.

Written by Jesse McLaren, with comments from Smith An 85 year old with a history of CAD presented with 3 hours of chest pain that feels like heartburn but that radiates to the left arm. There’s minimal concave ST elevation in III which does not meet STEMI criteria, so this ECG is "STEMI negative". Below is the ECG. Take home 1.
