Characterization and financial impact of implantable cardioverter-defibrillator patients without interventions 5 years after implantation
Key result
Five years after implantation, 43% of ICD patients had not received appropriate therapy, with primary prevention indication predicting freedom from therapy.

Reichlin et al. (2011) conducted an observational in Implantable cardioverter-defibrillator (ICD) indication (n=322). Implantable cardioverter-defibrillator (ICD) was evaluated on Freedom from appropriate ICD therapy at 5 years. Five years after implantation, 43% of ICD patients had not received appropriate therapy, with primary prevention indication predicting freedom from therapy.
