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]

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." 2014 AHA/ACC guideline for the management of patients with non–ST-elevation acute coronary syndromes. Circulation , 130 (25).

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%

LVH and the diagnosis of STEMI - how should we apply the current guidelines? Journal of Electrocardiology 47 (2014) 655–660. This one mimics inferior STEMI (Figure 4): Concentric LVH, NO wall motion abnormality Case 5. How about diagnosing anterior STEMI in the setting of LVH? All troponins were negative.

This blog post reviews the basics for predicting the " C ulprit" A rtery — as well as the importance of the term, " O MI" ( = O cclusion-based MI ) as an improvement from the outdated STEMI paradigm. ECG Blog #294 — How to tell IF the "culprit" artery has reperfused. ECG Blog #194 — AIVR as a sign that the "culprit" artery has reperfused.

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). The 4th, after the opening of the artery and release of troponin from the cardiac circulation, was 99.9
