Assault-induced Takotsubo cardiomyopathy associated with persisting anterograde amnesia and myopathy.
Takotsubo cardiomyopathy is characterized by transient left ventricular dysfunction, electrocardiographic changes, and minimal release of myocardial enzymes that mimic acute myocardial infarction in patients without coronary artery disease. Takotsubo cardiomyopathy is frequently triggered by emotional or physical stress and occurs primarily in post-menopausal women. The pathomechanism of Takotsubo cardiomyopathy is, so far, unknown. Stress-induced amnesia is probably induced by perturbation of the hippocampal function. Assault-induced Takotsubo cardiomyopathy associated with amnesia has not been reported so far. In a 77-year-old Caucasian female, hospitalized because of confusion, anterograde amnesia, and hypertension after she had been assaulted by a female who sneaked up to her when she was unlocking the door of her apartment, Takotsubo cardiomyopathy was diagnosed based on clinical findings, electrocardiography, echocardiography, and coronary angiography. Follow-up after 8 weeks showed a regression of electrocardiographic and echocardiographic abnormalities; the amnesia for the assault, however, remained unchanged. This case shows that Takotsubo cardiomyopathy may be triggered by emotional stress induced during an assault. Assault-induced stress may not only induce Takotsubo cardiomyopathy but also amnesia for some of the events that occurred during the act.
