Echocardiogram STEMI Stenosis

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).

This is a 45 yo male who had an inferior STEMI 6 months prior, was found to have severe LAD and left main disease, and was supposed to be set up for CABG a few weeks later, but did not follow up. But it could be anterior STEMI. 40% of anterior STEMI has upward concavity in all of leads V2-V6. is likely anterior STEMI).

This ECG was read as “No STEMI” with no prior available for comparison. It is true this ECG does not meet STEMI criteria (there is 1.0 The Queen of Hearts sees it of course: Still none of these three ECGs meet STEMI criteria. Do you think we discussed this patient's 2-3 hour delay to reperfusion in our quarterly "STEMI meeting"?

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. Angiography revealed a 30% nonobstructive stenosis of the mid LAD.

Now it is a full blown STEMI of 3 myocardial territories: inferior, posterior, and lateral But at least it does not call it "Normal." Angiogram findings included: 95% mid RCA stenosis with occluded distal right PDA secondary to thrombus (peristent OMI). Formal echocardiogram: Systolic function is at the lower limits of normal.

Only very slight STE which does not meet STEMI criteria at this time. I am immediately worried that this OMI will not be understood, for many reasons including lack of sufficient STE for STEMI criteria, as well as the common misunderstanding of "no reciprocal findings" which is very common with this particular pattern.

An echocardiogram confirmed aortic stenosis with a large pressure gradient. Thus, this patient had increased ST elevation (current of injury) superimposed on the ST elevation of LVH and simulating STEMI. The next day, and angiogram showed normal coronary arteries. He awoke and did well.
