A 34-year-old woman developed Takotsubo cardiomyopathy triggered by a combination of iatrogenic thyrotoxicosis from levothyroxine replacement therapy and physical stress from a recent Caesarean section.
Case Report (n=1)
Iatrogenic thyrotoxicosis from levothyroxine replacement therapy, combined with the physical stress of a recent Caesarean section, can trigger Takotsubo cardiomyopathy.
Alerts clinicians to thyrotoxicosis as possible Takotsubo trigger post-Caesarean; leaves open causality and requires prospective confirmation.
The patient was a 34-year-old woman presented to the emergency department with a chest pain. During the last two years she took replacement therapy with levothyroxine because of lymphocytic thyroiditis. The ECG upon admittance verifies tall T waves in the precordial leads and the subsequent ECG shows a negativation of the T wave in the precordial leads. In the patient’s echocardiographic findings, dyskinesia of the apical anterior segment is found, in laboratory findings increased levels of cardioselective biomarkers are present. Afterwards, a coronary angiography is done and no significant stenosis was detected in any coronary arteries, and ventriculography showed hypokinesia anterior mid segments. Considering all this, the diagnosis of Takotsubo cardiomyopathy is set, iatrogenically caused by thyrotoxicosis in combination with the recent Caesarean section.

Maričić et al. (2015) conducted a case report in Takotsubo cardiomyopathy (n=1). Levothyroxine (iatrogenic thyrotoxicosis) was evaluated on Development of Takotsubo cardiomyopathy. A 34-year-old woman developed Takotsubo cardiomyopathy triggered by a combination of iatrogenic thyrotoxicosis from levothyroxine replacement therapy and physical stress from a recent Caesarean section.
