Trends in hospitalization for takotsubo cardiomyopathy in the United States.

ABSTRACT:

Background

Takotsubo (or stress induced) cardiomyopathy is characterized by transient left ventricular systolic dysfunction. Recent trends in patient volume, characteristics, and outcomes in the United States are unknown.

Methods

Using 2007-2012 National Inpatient Sample data, we identified 22,005 adults (≥18 years) with a primary and 31,942 adults with a secondary discharge diagnosis of takotsubo cardiomyopathy (International Classification of Diseases, Ninth Revision, code 429.83) who underwent diagnostic coronary angiography.

Results

During 2007 to 2012, the incidence of takotsubo cardiomyopathy increased over 3-fold: 52/million discharges in 2007 to 178/million in 2012 (P < .001). We found a temporal increase in the prevalence of cardiac arrest, cardiogenic shock,
