Conclusion and results:
Coronary artery embolism is a rare and fatal cause of acute myocardial infarction and has rarely been reported secondary to atrial fibrillation in takotsubo cardiomyopathy patients. Early diagnosis and treatment play a vital role in the prevention of short-term as well as long-term post-myocardial infarction complications. Physicians and cardiologists should have a low threshold for coronary artery embolism when encountering shock patients with atrial fibrillation, as early management prevents hazard complications.
