The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

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.

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. Just another NSTEMI.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?
