Takotsubo Syndrome in Neurologic Disease.

Abstract

Transient cardiac dysfunction, or Takotsubo cardiomyopathy, is a well-known complication among patients presenting with neurologic insult, who are described as having takotsubo syndrome. This condition is commonly associated with aneurysmal subarachnoid hemorrhage but has also been described in patients after cerebral surgery or in those with ischemic stroke, seizure, and traumatic brain injury. Current evidence suggests that cardiac dysfunction in these patients is a result of increases in catecholamines that are induced by supraphysiologic levels of sympathetic activity. The cardiac injury is typically reversible and carries a good prognosis, but secondary complications may arise if the diagnosis is not recognized early.
