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. See "Mechanisms of acute coronary syndromes related to atherosclerosis".)

The commonest causes of MINOCA include: atherosclerotic causes such as plaque rupture or erosion with spontaneous thrombolysis, and non-atherosclerotic causes such as coronary vasospasm (sometimes called variant angina or Prinzmetal's angina), coronary embolism or thrombosis, possibly microvascular dysfunction.

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. FFR can be useful.

Atherosclerotic cardiovascular disease (ASCVD), caused by plaque buildup in arterial walls, is one of the leading causes of disability and death worldwide.1,2 3 Patients with ASCVD are at a higher risk for major adverse cardiovascular events (MACE) including heart attack or myocardial infarction (MI), stroke, and cardiovascular (CV) death.4

Smith Major Learning Point: The worst risk factor for a bad outcome in OMI is young age because cardiologists cannot believe that a young person can have an OMI. Only after her troponin peaked at 500,000 ng/L did she get her angiogram, which showed a 100% left main occlusion due to ruptured plaque. This gets drilled into them.
