Predictors of Early Mortality in Patients Age 80 and Older Receiving Implantable Defibrillators

Abstract

In general, patients > or = 80 years of age who meet current indications for ICD implantation live sufficiently long to warrant device implantation based on anticipated survival alone. However, those with an EF < or = 20% have a markedly elevated 1-year mortality with no observed increase in appropriate ICD therapy, thus reducing the benefit of device implantation in this population.
