| Summary: | Takotsubo cardiomyopathy (TC) is an atypical, severe but reversible form of acute heart insufficiency. It typically presents
with left ventricular failure, transient apical and mid-segments hypokinesis, absence of significant coronary stenosis and
new electrographic abnormalities and/or elevation in serum cardiac enzymes. Although TC (‘broken heart syndrome’)
has classically been associated with emotional trauma, evidence suggests that other precipitants might exist, including
iatrogenic and thyroid-mediated forms. Thyroid disease is a relatively common comorbidity in TC patients. We report a
case of TC in a postmenopausal female with no history of emotional trauma or other potential precipitant factors who
was diagnosed with amiodarone-induced hyperthyroidism during her hospital stay. Though some case reports of thyroidrelated
TC exist, we are not aware of any other reported case of TC precipitated by amiodarone-induced hyperthyroidism. |
