Myocardial infarction in the absence of obstructive coronary artery disease (MINOCA) is a frequent clinical scenario observed in approximately 5% of all patients with acute myocardial infarction (AMI) who are referred for coronary angiography. MINOCA is defined as any AMI in the presence of nonobstructive coronary arteries (i.e., no diameter stenosis ≥ 50% in a major epicardial vessel) and no other clinically overt specific cause that can justify the acute presentation [1].
