Dynamic OMI ECG. Negative trops and negative angiogram does not rule out coronary ischemia or ACS.

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%.

Intravascular Imaging Can Improve Outcomes for Complex Stenting Procedures

The ECLIPSE trial shows that use of IVI to guide coronary stenting in severely calcified lesions prevents death, stent thrombosis, and unplanned repeat procedures in this high-risk patient population. The ECLIPSE trial results were presented at the American College of Cardiology Scientific Session (ACC.25)

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. Type I ischemia. Type II ischemia.

What does the angiogram show? The Echo? The CT coronary angiogram? How do you explain this?

Dr. Smith's ECG Blog

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.

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.

See this "NSTEMI" go unrecognized for what it really is, how it progresses, and what happens

Dr. Smith's ECG Blog

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.

Upon arrival to the emergency department, a senior emergency physician looked at the ECG and said "Nothing too exciting."

To prove there is no plaque rupture, you need to do intravascular ultrasound (IVUS). An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!! One of the most common is rupture of a non-obstructive plaque, with thrombus formation and OMI that spontaneously lyses and leaves a wide open artery. It can only be seen by IVUS.
