Biventricular Takotsubo cardiomyopathy in Graves hyperthyroidism

J Invasive Cardiol. 2014 Mar;26(3):E35-6.

Abstract

Graves hyperthyroidism is commonly seen in clinical practice and Takotsubo stress cardiomyopathy is an increasingly recognized cardiac complication of physical or emotional stress. We report the rare case of a patient with Graves hyperthyroidism that was complicated by severe biventricular takotsubo cardiomyopathy, which was demonstrated on heart catheterization. After appropriate pharmacologic treatment of her hyperthyroidism, she had complete resolution of her cardiomyopathy.
