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.

If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA. Here is my comment on MINOCA: "Non-obstructive coronary disease" does not necessarily imply "no plaque rupture with thrombus." They often cannot even be recognized as culprits, as fissured or ulcerated plaque. myocarditis).

BACKGROUND:A modified computed tomography angiography (CTA)based Carotid Plaque Reporting and Data System (Plaque-RADS) classification was applied to a cohort of patients with embolic stroke of undetermined source to test whether high-risk Plaque-RADS subtypes are more prevalent on the ipsilateral side of stroke.

About a fifth of all ischemic strokes are attributed to embolization of ruptured atherosclerotic plaque from carotid arterial stenosis. But it has been difficult to predict which person with asymptomatic carotid artery stenosis is likely to progress to symptomatic carotid disease and stroke. J Am Coll Cardiol.

The Neuroguard Integrated Embolic Protection (IEP) system is an experimental treatment for carotid artery stenosis, also known as carotid artery disease, a condition in which fatty-waxy deposits known as plaque builds up and blocks the normal flow of blood in the large arteries on either side of the neck.

In addition, the top left blue arrow indicates a section in the LAD with a severe stenosis, likely the culprit for the prior L A D occlusion which has since recanalized. Then, part of the thrombus embolized into the LCx causing an inferoposterolateral OMI. (As There are also diagonal branches which are not well visualized.
