Effect of age on in‐hospital outcomes of transvenous lead extraction for infected cardiac implantable electronic device

Abstract

AbstractBackgroundThe real‐world data on the safety profile of transvenous lead extraction (TLE) for infected cardiac implantable electronic devices (CIED) among elderly patients is not well‐established. This study aimed to evaluate the hospital outcomes between patients of different age groups who underwent TLE for infected CIED.MethodUsing the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent TLE for infected CIED between 2017 and 2020. We divided the patients into four groups: Group A. Young (<50 years), Group B. Young intermediate (50–69 years old), Group C. Older intermediate (70–79 years old), and Group D. Octogenarian (≥80 years old). We then analyzed the in‐hospital outcome and 30‐day readmission between these age groups.ResultsA total of 10,928 patients who were admitted for TLE of infected CIED were included in this study: 982 (9.0%) patients in group A, 4,234 (38.7%) patients in group B, 3,204 (29.3%) patients in group C and 2,508 (23.0%) of patients in group D. Our study demonstrated that the risk of early mortality increased with older age (Group B vs. Group A: OR: 1.92, 95% CI: 1.19‐3.09, p < .01; Group C vs. Group A: OR: 2.47, 95% CI: 1.51‐4.04, p < .01; Group D vs. Group A: OR: 2.82, 95% CI: 1.69‐4.72, p < .01). The risk of non‐home discharge also increased in elderly groups (Group B vs. Group A: OR: 1.89; 95% CI: 1.52‐2.36; p < .01; Group C vs. Group A: OR: 2.82; 95% CI 2.24‐3.56; p < .01; Group D vs. Group A: OR: 4.16; 95% CI: 3.28‐5.28; p < .01). There was no significant difference in hospitalization length and 30‐day readmission between different age groups. Apart from a higher rate of open heart surgery in group A, the procedural complications were comparable between these age groups.ConclusionElderly patients had worse in‐hospital outcomes in early mortality and non‐home discharge following the TLE for infected CIED. There was no significant difference between elderly and non‐elderly groups in prolonged hospital stay and 30‐day readmission. Elderly patients did not have a higher risk of procedural complications.
