I sent this to the Queen of Hearts So the ECG is both STEMI negative and has no subtle diagnostic signs of occlusion. Similarly, if a patient with known CAD presents with refractory ischemic chest pain, the ECG barely matters: the pre-test likelihood of acute coronary occlusion is so high that they need an emergent angiogram.

A man in his mid 60s with history of CAD and stents experienced sudden onset epigastric abdominal pain radiating up into his chest at home, waking him from sleep. She knows the baseline is normal, and she knows the STEMI(-) OMI one is diagnostic of OMI, with the highest possible confidence. We've come a long way in 2 years!

Sent by Anonymous, written by Pendell Meyers A man in his 60s with history of CAD and 2 prior stents presented to the ED complaining of acute heavy substernal chest pain that began while eating breakfast about an hour ago, and had been persistent since then, despite EMS administering aspirin and nitroglycerin.

Concerning history, known CAD" Recorded 2 hours after pain onset: What do you think? The patient was diagnosed with a"Non-STEMI." Traditionally , Occlusion MI (OMI) myocardial infarctions that are not STEMI are called NonSTEMI. This was my response: "This looks like a worrisome EKG. But by now you must have a repeat ECG.

Since then, I started looking for OMI EKG findings and not just STEMI. Remember: these findings above are included as STEMI equivalent findings in the 2022 ACC Expert Consensus Decision Pathway on ACS Patients in the ED. mm in lead I, thus not STEMI criteria) and was finally understood by the cardiologist. Teaching is rewarding!

This was a middle aged female with a h/o CAD who presented to the ED by EMS sudden onset of central chest pressure 45 min prior to ED arrival with associated diaphoresis and SOB.  There is LVH and there are ST-T abnormalities (large inferior T-waves and ST elevation, with reciprocal findings in aVL).

No family history of sudden cardiac death, cardiomyopathy, premature CAD, or other cardiac issues. 50% of LAD STEMIs do not have reciprocal findings in inferior leads, and many LAD OMIs instead have STE and/or HATWs in inferior leads instead. The ECG easily meets STEMI criteria in all leads V2-V6, as well. Pericarditis?
