Abstract 20796: Effect of in Situ Automatic Implantable Cardioverter-Defibrilator(AICD) on the in Hospital Outcomes in the Patients With Takotsubo Cardiomyopathy

Introduction: Hospitalizations of takotsubo cardiomyopathy (TTC) have been rising in last decade. There is limited data reporting mortality associated with the disease. It can occasionally present as sudden cardiac death secondary to fatal arrhythmias, especially in the patients with long QT interval. TTC itself can prolong QT interval and in such patients automated implantable cardioverter defibrillator (AICD) is used to prevent fatal arrhythmias. Hypothesis: We assessed the effect of previously inserted AICD in patients with TTC on outcomes of in- hospital mortality, length of stay, cardiac arrest and hospitalization costs. Methods: We used the Nationwide Inpatient Sample (NIS) database to estimate annual hospitalizations from 2006-2012 with principal discharge diagnosis TTC. We used ICD-9 code 429.83 to identify TTC related hospitalizations and implantation of AICD at the time of hospitalization was identified by ICD-9-CM diagnosis code V45.02. Multivariate logistic regression analyses were performed t...
