A Case of Grave's Thyrotoxicosis-Induced Takotsubo Cardiomyopathy Presenting with Cardiac Arrest After Winning the Lottery.

Takotsubo syndrome (TTS) is a nonischemic cardiomyopathy with transient apical ballooning of the left ventricle and reduced ejection fraction that can be caused by severe emotional or physical stress, with diverse clinical presentations. This case describes a patient who went into cardiac arrest at a casino after winning the lottery. She was found to have Takotsubo cardiomyopathy, in the setting of uncontrolled hyperthyroidism. This is a very unique case of TTS presenting with cardiac arrest, and is also an uncommon example of TTS triggered by a positive rather than negative emotional life event.
