The provider had sent the patient for an aortic dissection scan which had shown extremely heavy calcification of the LAD. There was a 100% proximal LAD occlusion that was opened and stented. The cath lab was activated. But 45 minutes later than it should have been.

The Queen of Hearts disagrees, diagnosing OMI with high confidence: Case Continued: The EKG was not immediately recognized by the emergency provider, who ordered a CT scan to rule out aortic dissection at 1419. This was a presumed culprit and a stent was placed. Assuming that was indeed a culprit, then this was ACS.

As his pain was very severe, emergency physicians concerned of aortic dissection and ordered a thoracic CT scan. The lesion was successfully stented. Take home messages: 1- In STEMI/NSTEMI paradigm you search for STE on ECG. Bi-phasic scan showed no dissection or pulmonary embolism. Turk Kardiyol Dern Ars. doi: 10.5543/tkda.2021.21026.

The "criteria" for posterior STEMI are 0.5 Is it STEMI or NonSTEMI? The patient had no hypertension, no tachycardia, a normal hemoglobin, no drug use, no hypotension/shock, no murmur of aortic stenosis. We also looked at his aortic root by both parasternal and suprasternal views, and the aorta was normal.]

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).

A middle-aged male with h/o CAD and stents presented with typical chest pressure. It may be difficult to read STEMI in the setting of RBBB. There is, however, a long QT also, with abnormal T-waves, but this is not STEMI. So there is pathologic ST elevation here, consistent with anterolateral STEMI. What do you think?

When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?
