Methods: Retrospective single cardiovascular surgery center cohort study of definite CIED-IE episodes between 1981-2020. A comparative analysis of two periods (1981-2000 vs 2001-2020) was conducted to analyze changes in epidemiology and outcome over time. Results: One-hundred and thirty-eight CIED-IE episodes were diagnosed: 25 (18%) first period and 113 (82%) second. CIED-IE was 4.5 times more frequent in the second period, especially in implantable cardiac defibrillators. Age (63 [53-70] vs 71 [63-76] years, P < .01), comorbidities (CCI 3.0 [2-4] vs 4.5 [3-6], P > .01), nosocomial infections (4% vs 15.9%, P = .02) and transfers from other centers (8% vs 41.6%, P < .01) were significantly more frequent in the second period, as were methicillin-resistant coagulase-negative staphylococcal (MR-CoNS) (0% vs 13.3%, P < .01) and Enterococcus spp. (0% vs 5.3%, P = .01) infections, pulmonary embolism (0% vs 10.6%, P < .01) and heart failure (12% vs 28.3%, p < .01). Second period surgery rates were lower (96% vs 87.6%, P = .09), and there were no differences in in-hospital (20% vs 11.5%, P = .11) and one-year mortalities (24% vs 15%, P = .33), or relapses (8% vs 5.3%, P = 0.65). Multivariate analysis showed Charlson index (hazard ratios [95% confidence intervals]; 1.5 [1.16-1.94]) and septic shock (23.09 [4.57-116.67]) were associated with a worse prognosis, whereas device removal (0.11 [.02-.57]), transfers (0.13 [.02-0.95]), and second-period diagnosis (0.13 [.02-.71]) were associated with better one-year outcomes. Conclusions: CIED-IE episodes increased more than four-fold during last 40 years. Despite CIED-IE involved an older population with more comorbidities, antibiotic-resistant MR-CoNS, and complex devices, one-year survival improved.11 p.application/pdfengcc-by-nc-nd (c) Hernández-Meneses, Marta et al., 2022https://creativecommons.org/licenses/by-nc-nd/4.0/Pronòstic mèdicEpidemiologiaEndocarditisPrognosisEpidemiologyEndocarditisinfo:eu-repo/semantics/article7296272023-03-10info:eu-repo/semantics/openAccess933259636381626
