Geriatric Conditions in Patients Undergoing Defibrillator Implantation for Prevention of Sudden Cardiac Death: Prevalence and Impact on Mortality.

ABSTRACT:

Background

Geriatric conditions may influence outcomes among patients receiving implantable cardioverter-defibrillators (ICDs). We sought to determine the prevalence of frailty and dementia among older adults receiving primary prevention ICDs and to determine the impact of multimorbidity on mortality within 1 year of ICD implantation.

Methods and results

The cohort included 83 792 Medicare patients from the National Cardiovascular Data Registry ICD Registry who underwent first primary prevention ICD implantation between 2006 and 2009. These data were merged with Medicare analytic files to determine the prevalence of frailty, dementia, and other conditions before ICD implantation, as well as 1-year mortality. A validated claim-based algorithm was used to identify frail patien
