It should be known that each category can easily manifest the generic subendocardial ischemia pattern. In general, subendocardial ischemia is a consequence of global supply-demand mismatch that usually ameliorates upon addressing, and mitigating, the underlying cause. What’s interesting is that the ECG can only detect ischemia.

Angiography : LMCA — 90-99% osteal stenosis. LCx — 50-69% stenosis of the 1st marginal branch; with 100% distal LCx occlusion. The patient in today’s case presented in cardiogenic shock from proximal LAD occlusion, in conjunction with a subtotally stenosed LMCA. There is no definite evidence of acute ischemia. (ie,

Contrary to what Ken stated, the ST vector remains mostly posterior __ What about subendocardial ischemia? Subendocardial ischemia results in ST depression, but unfortunately, and rather mysteriously, it does not localize to the ischemic wall. Similarly, STD in aVL is usually reciprocal to inferior ST elevation, not "lateral ischemia."

His response: “subendocardial ischemia. History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. Anything more on history?

The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. The patient is started on epinephrine infusion for cardiogenic shock and cardiology took the patient to the cath lab. The Queen of Hearts sees it of course: Still none of these three ECGs meet STEMI criteria.

Now appears to be in cardiogenic shock." This is ischemia until proven otherwise. However, cardiogenic shock usually takes some time to develop, so it is probably subacute." Here I annotate it: This shows 100% occluded circumflex (red arrow) and a 90% stenosis of the LAD (Yellow arrow).
