Takotsubo Cardiomyopathy in Guillain–Barré Syndrome

Takotsubo cardiomyopathy (TCM) is a serious autonomic complication of Guillain–Barré syndrome (GBS). However, the association between TCM and GBS has not been investigated in detail. We investigated the characteristics of GBS patients with TCM (GBS-TCM). Clinical features and anti-ganglioside antibody between the GBS-TCM patients and 62 classical GBS patients without TCM as control patients were compared. Eight GBS-TCM patients were identified, in whom TCM was diagnosed at a mean of 6.5 [range 3–42] days after the onset of GBS. The age at onset of GBS was elder in the GBS-TCM patients than in the control GBS patients (76.5 [56–87] vs. 52 [20–88] years, p < 0.01). Notably, cranial nerve deficits, particularly in the lower cranial nerves, were observed in all GBS-TCM patients (100
