Implantable Cardioverter-Defibrillators Use Among Elderly Patients Receiving Cardiac Resynchronization: A Meta-Analysis.

CONCLUSIONS: In conclusion, ICD therapy was used less frequently in patients ≥75 years old compared to younger patients receiving CRT. Future studies evaluating the efficacy and effectiveness of ICDs in elderly patients with indications for CRT are needed to guide management of this increasing population. CONDENSED ABSTRACT: It remains unclear whether elderly patients undergoing cardiac resynchronization therapy derive the same additional benefit from implantable cardioverter defibrillator as younger patients. We summarized six observational studies of cardiac resynchronization enrolling 613 elderly (patients ≥75 years old) and 2,810 patients <75 years old. There was significantly less implementation of defibrillators in elderly patients compared to the younger patients (37.9% versus 64.3%) (odds ratio: 0.26; 95% confidence intervals: 0.14 to 0.46 p < 0.0001). We concluded that implantable cardioverter-defibrillators were utilized less frequently in elderly patients who underwent cardiac resynchronization therapy.
