This case shows a CT image of subendocardial ischemia. However, there are also Q-waves inferiorly and the inferior T-waves are inverted, suggesting that this is an old MI with persistent ST elevation, or, alternatively, a subacute or partially reperfused, inferior STEMI. This is all but diagnostic of inferior-posterior STEMI.

Important point: when there is diffuse subendocardial ischemia but no OMI, a wall motion abnormality will not necessarily be present. They agreed ischemia was likely in the setting of demand given DKA and infection. That this is all demand ischemia is unlikely. Lung exam showed diffuse B lines bilaterally. Aslanger's pattern.

Angiogram No obstructive epicardial coronary artery disease Cannot exclude non-ACS causes of troponin elevation including coronary vasospasm, stress cardiomyopathy, microvascular disease, etc. Detailed coronary artery evaluation not performed. This suggests further severe ischemia.

Written by Bobby Nicholson What do you think of this “STEMI”? CTA head and neck were obtained and showed no evidence of intracranial hemorrhage, large vessel occlusion stroke (what a helpful and apt name for an acute arterial occlusion paradigm, by the way.), or basilar ischemia. The patient is unconscious and hypoxic.

Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. What do you see?

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. His response: “subendocardial ischemia. Anything more on history? POCUS will be helpful.”

The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. There is no definite evidence of acute ischemia. (ie, Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( The below ECG was recorded.
