Long-term survival of elderly patients after pacemaker implatation

Area of Science:

• Cardiology
• Geriatric Medicine
• Biomedical Engineering

Background:

• Pacemaker implantation is a common procedure for cardiac rhythm disorders.
• Limited data exists on the long-term outcomes of pacemaker implantation in the very elderly population (above 70 years).

Purpose of the Study:

• To evaluate the safety and efficacy of pacemaker implantation in patients aged 70 years and above.
• To assess the survival rates and quality of life in this specific elderly cohort.

Main Methods:

• Follow-up study of 80 patients (average age 75.4 years) with implanted pacemakers.
• Analysis of implantation types (epicardial vs. endocardial) and indications (atrioventricular block vs. sick-sinus syndrome).
• Calculation of survival rates at 1, 2, 3, 4, and 5 years post-implantation.

Main Results:

• Overall survival rates at 1, 2, 3, 4, and 5 years were 90.0%, 82.1%, 74.1%, 67.2%, and 58.3%, respectively.
• Survival rates in the first three years were comparable to younger patient groups.
• No new myocardial infarction episodes were observed during the follow-up period.

Conclusions:

• Endocardial pacemaker implantation is a safe and effective procedure in elderly patients (over 70).
• The procedure significantly prolongs life and improves quality of life in this age group.
• Operative risk is low, making it a viable treatment option for advanced age patients.
