Takotsubo Cardiomyopathy and Stroke
The incidence and type of stroke in the setting of takotsubo cardiomyopathy (TC) can vary, depending on the patient population being studied [1–5]. For this reason, we sought to investigate the occurrence of TC together with stroke at our institution (Mayo Clinic, Scottsdale, Arizona). To do this, we identified all patients with a diagnosis of TC per ICD-9 (International Classification of Diseases, Ninth Edition) (ICD-9 code 429.83; October 1, 2006, to October 31, 2011) (Table 1) or apical ballooning syndrome (ICD-9 code 419.89; January 1, 2006, to September 30, 2006) in a retrospective analysis of the electronic medical records.
