This confirms that the pain was ischemia and is now resovled. Thus, it has recently become generally accepted that most plaque ruptures resulting in myocardial infarction occur in plaques that narrow the lumen diameter by 40% of the arterial cross section may be involved by plaque. The i nitial hs troponin I returned 75%.

This suggests further severe ischemia. MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection; myocardial disorders, including myocarditis, takotsubo cardiomyopathy, and other cardiomyopathies. And yet the arteries remain open.

The ECG in the chart was read as "no obvious ST changes," (even though no previous ECG was available) and the formal read by the emergency physicians was: "ST deviation and moderated T-wave abnormality, consider lateral ischemia." Consequences of reocclusion after successful reperfusion therapy in acute myocardial infarction.

The baseline ECG is basically normal with no ischemia. You can see in the lead-specific analysis that she "sees" the STD in V5, V5, and II, with STE in aVR as signs of "Not OMI", because subendocardial ischemia pattern is not the same as OMI. In my opinion, I think it looks more like subendocardial ischemia. Am J Emerg Med.

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?

Such cases are classified as MINOCA (Myocardial Infarction with Non-Obstructed Coronary Arteries). MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection. An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!!

There is broad subendocardial ischemia as demonstrated by STE aVR with concomitant STD that almost appears appropriately maximal in Leads II and V5. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. This is the initial ECG: The QRS is widened with a regular cadence, and there are no discernable P waves.
