Why the study?
Coronary embolus and other nonatherosclerotic causes of acute MI remain underappreciated as potential etiologies of acute coronary syndromes.
Highlights coronary artery embolism secondary to atrial fibrillation from thyrotoxicosis as an underrecognized cause of acute myocardial infarction.
May warrant vigilance for cardioembolic STEMI in thyrotoxicosis with new AF; leaves open need for larger studies to define incidence.
Nonatherosclerotic causes of acute myocardial infarction (MI) are infrequent, with atrial fibrillation as the most common etiology in cases of embolic MI. This entity, however, along with other causes of coronary embolus remains underappreciated as a probable cause of acute coronary syndromes. [1] Our case delineates a rare presentation of STEMI due to cardioembolic origin secondary to atrial fibrillation in a patient with thyrotoxicosis, previously undiagnosed to have an abnormal cardiac rhythm.
