Reverse Takotsubo Cardiomyopathy and Shock Supported by Continuous Hemodiafiltration in a Patient with Anorexia Nervosa

Abstract

Background: Takotsubo cardiomyopathy (TC) is known as stress-induced cardiomyopathy. It is characterized by relatively benign transient systolic dysfunction of the apical segments of the left ventricle. Reverse Takotsubo cardiomyopathy (RTC) is a rare variant of TC. Here we describe a rare case of RTC and cardiogenic shock in a patient with anorexia nervosa (AN). Case presentation: A 54-year-old woman with AN showed RTC due to subarachnoid hemorrhage (SAH) stress; renal replacement therapy including continuous hemodiafiltration (CHDF) was successfully performed to maintain her cardiohemodynamic state. Conclusion: To our knowledge, this is the first documented report showing that renal replacement therapy greatly contributed to the circulation management and recovering kidney dysfunction with anuria in a patient with an eating disorder and RTC.
