Why the study?
MINOCA is often considered a dynamic working diagnosis requiring further investigation, with thromboembolic mechanisms representing a major cause.
This review summarizes the etiology, pathophysiologic mechanisms, diagnosis, and treatment of thromboembolic causes of MINOCA.
Synthesizes thromboembolic MINOCA evidence; leaves open the need for prospective trials before guiding practice.
Acute myocardial infarction (AMI) usually represents the clinical manifestation of atherothrombotic coronary artery disease (CAD) resulting from atherosclerotic plaque rupture. However, there are cases in which coronary angiography or coronary computed tomography angiography reveals patients with acute coronary syndrome with non-obstructive CAD. This clinical entity is defined as myocardial infarction with non-obstructive coronary arteries (MINOCA) and often considered as a clinical dynamic working diagnosis that needs further investigations for the establishment of a final etiologic diagnosis. The main causes of a MINOCA working diagnosis include atherosclerotic, non-atherosclerotic (vessel-related and non-vessel-related), and thromboembolic causes This literature review aimed to investigate the major thromboembolic causes in patients presenting with MINOCA regarding their etiology and pathophysiologic mechanisms, as well as diagnostic and treatment methods.
