Based on recent studies, current guidelines recommend that O2 should not be given to non-hypoxemic patients with STEMI or NSTEMI [2,3]. REBEL Cast Ep114 – High Flow O2, Suspected ACS, and Mortality? 4159 patients (10% of total population) had STEMI 30d Mortality: High O2 protocol: 8.8% Low O2 protocol: 3.1%

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." Smith : As Willy states, ACS with persistent symptoms is a guideline recommended indication for ＜2 hour angio (both ACC/AHA and ESC).

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]

This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. His response: “subendocardial ischemia. Anything more on history? POCUS will be helpful.”

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%

This is all but diagnostic of STEMI, probably due to wraparound LAD The cath lab was activated. 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.

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. Patients with ACS and hemodynamic instability 2.
