Pacemaker implantation in Singapore in 1997

Area of Science:

• Cardiology
• Medical Device Technology
• Public Health

Background:

• Previous studies on pacemaker implantation in Singapore originated from single institutions, potentially limiting generalizability.
• A comprehensive survey was conducted in 1997 as part of a global initiative to accurately assess pacemaker implantation practices nationwide.

Purpose of the Study:

• To determine the national pacemaker implantation rate in Singapore for the year 1997.
• To analyze patient demographics, indications for pacing, and types of pacemakers used.
• To establish a baseline for future trends in pacemaker implantation in Singapore.

Main Methods:

• Data collection involved information from pacemaker manufacturers and a survey distributed to all physicians performing pacemaker implantations.
• Information was gathered on 206 pacemaker implantations and replacements that occurred in Singapore during 1997.
• Detailed patient and implantation data were obtained for 78% of the cases.

Main Results:

• The overall pacemaker implantation rate was 69 per million population, with new implants at 61 per million.
• The majority of recipients were females (62.5%), with a mean age of 68.5 years; 79% were over 60.
• Heart block (52.8%) and sick sinus syndrome (43.0%) were the primary indications, with single-chamber pacemakers being most common (75%).

Conclusions:

• Pacemaker implantation in Singapore in 1997 was 69 per million, with heart block as the leading indication and single-chamber devices predominant.
• The findings highlight a significant utilization in the elderly population, suggesting a future increase in demand due to Singapore's aging demographic.
• This study provides crucial data for understanding and planning cardiac pacing services in Singapore.
