Key result
Unrecognized hyperthyroidism presents as coronary vasospasm-induced MI, successfully managed with methimazole and diltiazem.
Why the study?
Coronary vasospasm leading to myocardial infarction is a rare cardiac presentation of hyperthyroidism, often recognized only after diagnosis of thyrotoxicosis.
Case Report (n=1)
Screening for hyperthyroidism may be considered in unexplained vasospasm; leaves open whether this improves ACS outcomes.
Hyperthyroidism can present with cardiac issues, such as tachycardia, atrial fibrillation, and high output congestive heart failure. Rare case reports of coronary vasospasm leading to myocardial infarction (MI) are published. Of these cases, many are known to be hyperthyroid prior to cardiac presentation. We report a female patient with unrecognized thyrotoxicosis who presents with acute MI secondary to coronary vasospasm.

Ataallah et al. (2020) conducted a case report in Myocardial infarction secondary to coronary vasospasm and unrecognized hyperthyroidism (n=1). Unrecognized hyperthyroidism was evaluated on Clinical presentation and symptom resolution. Unrecognized hyperthyroidism can present as acute myocardial infarction secondary to coronary vasospasm, which was successfully managed with methimazole and diltiazem.
