Written by Jesse McLaren A 70 year old with prior MIs and stents to LAD and RCA presented to the emergency department with 2 weeks of increasing exertional chest pain radiating to the left arm, associated with nausea. I sent this to the Queen of Hearts So the ECG is both STEMI negative and has no subtle diagnostic signs of occlusion.

Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." Here is the angiogram after stent placement. Immediate versus delayed invasive intervention for non-stemi patients. Kontos, M.

This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. It was stented. These include: i ) appreciation of how problematic the definition of “acute STEMI” can be; and , ii ) illustration of how dependence on this definition may result in overlooking acute coronary occlusion.

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%

The "criteria" for posterior STEMI are 0.5 Is it STEMI or NonSTEMI? It was opened and stented with a door to balloon time of about 120 minutes (this is long for STEMI, but very short for a high risk Non STEMI). This is from the 2014 ACC/AHA guidelines. The troponin I returned at 4.1 mm STE in one lead.

Submitted and written by Alex Bracey with edits by Pendell Meyers and Steve Smith Case A 50ish year old man with a history of CAD w/ prior LAD MI s/p LAD stenting presented to the ED with chest pain similar to his prior MI, but worse. Despite ongoing chest discomfort and an uptrending troponin, he never meets STEMI criteria.

At 1210, the case was discussed with a cardiologist at a PCI capable facility, who accepted the patient for transfer, noting the ST depression in anterior leads as consistent with ischemia but not a STEMI. The proximal and mid LAD stenoses were stented and the OM 2 was left alone. 5 years later ( now in 2025 ) the problem remains.
