Takotsubo cardiomyopathy with marked ST-segment elevation and electrical alternans complicated with hyperglycemic hyperosmolar state.
This is the first report of a case of Takotsubo cardiomyopathy with a hyperglycemic hyperosmolar state (HHS). This case presented with marked ST-segment elevation and electrical alternans, uncommon findings in Takotsubo cardiomyopathy. We believe that hyperosmolarity-induced myocardial dehydration and consequent increase in intracellular calcium concentration may be the mechanism of Takotsubo cardiomyopathy and electrical alternans in HHS.
