Myocardial ischemia may induce myocardial fibrosis, a condition that progressively leads to ventricular remodeling, heightening the risk of heart failure. 68 Ga-FAPI-04 PET/CT shows promise in assessing fibroblast activation in patients with early myocardial infarction characterized by prolonged myocardial ischemia.

Such a pattern is consistent with significant left main coronary artery stenosis. Angiography done after initial stabilization showed severe stenosis of distal left main coronary artery. ST segment elevation in aVR in proximal LAD occlusion before first septal is thought to be due to transmural ischemia of the basal part of the septum.

STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? The additional ST Elevation in V1 is not usually seen with diffuse subendocardial ischemia, and suggests that something else, like STEMI from LAD occlusion, could be present. Was this: 1) ACS with ischemia and spontaneous reperfusion?

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?

There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus. [1] STEMI was activated and the patient went to Cath on arrival.

Post by Smith and Meyers Sam Ghali ( [link] ) just asked me (Smith): "Steve, do left main coronary artery *occlusions* (actual ones with transmural ischemia) have ST Depression or ST Elevation in aVR?" That said, complete LM occlusion would be expected to have subepicardial ischemia (STE) in these myocardial territories: STE vector 1.
