Summary
This study found no significant gender differences in pacemaker mode selection. However, younger patients (<65 years) were more likely to receive dual-chamber (DDD) pacemakers, primarily due to higher rates of atrial fibrillation in older patients.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Device Technology
Background:
- Previous research indicates potential gender disparities in pacemaker selection.
- Understanding these differences is crucial for personalized cardiac device therapy.
Purpose of the Study:
- To investigate gender-specific differences in pacemaker mode selection among patients receiving their first implant.
- To analyze factors influencing pacemaker choice in relation to sex and age.
Main Methods:
- Retrospective analysis of pacemaker implant data from 2001-2003.
- Univariate and multivariate analyses to compare pacemaker mode selection between sexes, adjusting for covariates.
- Inclusion of 259 patients (132 male, 127 female).
Main Results:
- No significant gender difference was observed in dual-chamber (DDD) versus single-chamber pacemaker selection.
- Patients younger than 65 years were more likely to receive DDD pacemakers (P < 0.01).
- Higher prevalence of atrial fibrillation in older patients (> or =65 years) explained the age-related difference in DDD pacemaker selection.
Conclusions:
- Pacemaker mode selection shows no significant gender bias.
- Age is a significant factor, with younger patients more likely to receive DDD devices.
- Atrial fibrillation prevalence influences age-related pacemaker mode selection.
