A 60 yo with 2 previous inferior (RCA) STEMIs, stented, called 911 for one hour of chest pain. Here is his most recent previous ECG: This was recorded after intervention for inferior STEMI (with massive ST Elevation, see below), and shows inferior Q-waves with T-wave inversion typical of completed inferior OMI. ng/mL (quite large).

A prehospital “STEMI” activation was called on a 75 year old male ( Patient 1 ) with a history of hyperlipidemia and LAD and Cx OMI with stent placement. Additionally, a bedside echocardiogram showed no wall motion abnormality and normal LV function. He wrote most of it and I (Smith) edited.

In the available view of the sinus rhythm, we see normal variant STE which probably meets STEMI criteria in V4 and V5. In other words, the inferior "ST elevation" is due to the abnormal rhythm, and does not signify OMI or STEMI in any way. The emergent echocardiogram showed normal EF, no WMA, and normal valve function.

So we activated the Cath Lab Angiogram: Impression and Recommendations: Culprit for the patient's anterior ST segment myocardial infarction and out of hospital V-fib cardiac arrest is a thrombotic occlusion of the mid LAD The first troponin returned barely elevated at 36 ng/L (URL = 35) In our study of initial troponin in STEMI, 26.8%

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. See this case: what do you think the echocardiogram shows in this case?

Echocardiogram: The estimated left ventricular ejection fraction is 34% Regional wall motion abnormality-lateral, akinetic. OMI that are not STEMI can be very subtle and difficult to diagnose even though the findings are very specific. A massive acute OMI. Regional wall motion abnormality-inferior base ( this is the posterior wall ).

Later, I found old ECGs: 5 month prior in clinic: V5 and V6 look like OMI 9 months prior in clinic with no chest symptoms: V5 and V6 look like OMI 1 year prior in the ED with chest pain: V5 and V6 sure look like a STEMI For this ECG and chest pain in the ED, the Cath lab activated. But the angiogram was clean. There was no OMI.
