Myotonic Dystrophy and Stress Induced Cardiomyopathy: A Case Series.

Myotonic dystrophy type 1 (DM1) is an autosomal dominant disorder with a broad spectrum of systemic manifestations, including cardiac abnormalities. Takotsubo cardiomyopathy, a form of stress-induced transient heart failure, is not typically associated with DM1, and its occurrence in this patient population remains poorly characterized. This case series aims to describe two instances of Takotsubo cardiomyopathy in patients with DM1, highlighting potential links between the neuromuscular and cardiac pathophysiology of DM1 and stress-induced cardiomyopathy.
