Defibrillator exchange in the elderly.

ABSTRACT:

Background

Implantable cardioverter-defibrillator (ICD) therapy in elderly patients is controversial because survival benefits might be attenuated by nonarrhythmic causes of death.

Objective

The purpose of this study was to investigate the outcome of septuagenarians and octogenarians after ICD generator exchange (GE).

Methods

A total of 506 patients undergoing elective GE were analyzed to determine the incidence of ICD shocks and/or survival after GE. Patients were divided into a septuagenarian group (age 70-79 years) and an octogenarian group (age ≥80 years). The primary endpoint was death from any cause. Secondary endpoints were survival after appropriate ICD shock and death without experiencing ICD shocks after GE ("prior death").
