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. Fig 1 shows typical examples of two such plaques.

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. MINOCA I do not have the bandwidth here to write a review of MINOCA.

Anaphylaxis leads to plaque rupture or erosion leading to acute myocardial infarction (type II) and acute coronary stent thrombosis (type III). Here we share a case of Kounis syndrome type I caused by an allergy caused by a Cryptopteran bite.

To prove there is no plaque rupture, you need to do intravascular ultrasound (IVUS). An angiogram is a "lumenogram;" most plaque is EXTRALUMINAL!! Such cases are classified as MINOCA (Myocardial Infarction with Non-Obstructed Coronary Arteries). It can only be seen by IVUS. MINOCA has many etiologies. Learning Points: 1.

If the arrest was caused by acute MI due to plaque rupture, then the diagnosis is MINOCA. MINOCA: Myocardial Infarction in the Absence of Obstructive Coronary Artery Disease). Here is my comment on MINOCA: "Non-obstructive coronary disease" does not necessarily imply "no plaque rupture with thrombus." FFR can be useful.

New insights into the use of the 12-lead electrocardiogram for diagnosing acute myocardial infarction in the emergency department. Here is the abstract: Background Identification of ST elevation myocardial infarction (STEMI) is critical because early reperfusion can save myocardium and increase survival.
