Research Objective

To enhance clinical awareness and optimize preventive strategies for permanent pacemaker (PPM) implantation by investigating the incidence of pocket infections and identifying associated risk factors.

Methodology

Prospective study involving the follow-up of 500 patients who underwent PPM implantation over a one-year period. Patients were followed on the 2nd and 4th weeks after implantation. Pocket PPM infection was defined as the presence of local edema and redness or swelling with and without systemic signs of infection that required antibiotic therapy and/or device removal.

Discussion

PPM pocket infections are rare but serious complications. The temporal pattern of infections, predominantly within the first two weeks post-implantation, is significant. Identified risk factors such as diabetes mellitus, renal failure, and temporary pacing wire use necessitate careful consideration in clinical practice. Preventive strategies and close follow-up are crucial for reducing morbidity and mortality. The study also references various preventive measures and technological advancements aimed at reducing infection risks.

Key Findings

The overall incidence of PPM infection was 2.4% (12 cases) among the 500 patients followed over one year. The mean age of patients was 55.4 ± 14.2 years, with 58% being male. The most common indications for PPM implantation were atrioventricular block (42%), sick sinus syndrome (32%), and atrial fibrillation with slow ventricular response (18%). Diabetes mellitus, renal failure, and the use of temporary pacing wires were identified as significant risk factors for PPM infection. Infections primarily occurred within the first two weeks after implantation.

Conclusion

PPM pocket infection is a rare but serious complication that occurs mainly within the 2 weeks after implantation. Diabetes mellitus, renal failure, and the use of temporary pacing wires are significant risk factors. Prevention strategies and close follow-up are essential to reduce the morbidity and mortality associated with this complication.

Fact Check

1. Incidence of Infection: The study reported an overall incidence of PPM infection of 2.4% (12 cases out of 500 patients).
2. Patient Demographics: The mean age of the patients was 55.4 ± 14.2 years, and 58% were male.
3. Follow-up Period: Patients were followed for a median of 12 months.
