Key result
Elderly ICD recipients show similar all-cause survival compared to younger patients.
Why the study?
Concern exists about the benefit of implantable defibrillator therapy in elderly patients and its effect on mortality compared to younger patients.
Cohort (n=200)
Absolute Event Rate: 75% vs 74%
No takes yet. Share an insight, caveat, or question.
No significant age differences in ICD utility observed; leaves open whether elderly derive equivalent benefit, warranting prospective trials.
Geelen et al. (1997) conducted a cohort in Arrhythmia requiring implantable cardioverter defibrillator (n=200). Age ≥70 years vs. Age <70 years was evaluated on Cumulative survival from all-cause mortality. Elderly patients (≥70 years) receiving implantable cardioverter defibrillators had similar cumulative survival from all-cause mortality compared to younger patients (75% vs 74%).
