Sumario:FUNDING ACKNOWLEDGEMENTS: Type of funding sources: None. BACKGROUND: The incidence of death and infections in patients implanted with cardiac implantable electronic devices (CIEDs) are not fully known yet (1,2). PURPOSE: To describe the incidence of death and device’s infection and its potential predictors in a contemporary cohort of CIED patients. METHODS: All consecutive patients implanted with a CIED at our tertiary institution were prospectively enrolled. Follow-up was performed every six months and clinical events recorded by expert electrophysiologists. For the purpose of the present analysis, we considered patients with a potential follow-up of at least 24 months. RESULTS: Between 01/09/2018 and 01/09/2020, a total of 838 patients were enrolled (34.6% female; age 77 [70-84]; PADIT score 2 [2-4]). Pacemaker (PM) and implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy and defibrillator (CRT-D) were implanted in 569 (68%) and 269 (32%) patients respectively. All patients had pre-implant antibiotic prophylaxis and 5.5% had an antibiotic-eluting envelope. Follow-up data were available for 832 (99.2%) patients. After a median follow-up of 42.3 (30.2-56.4) months, 212 (25.5%) patients died and 5 (0.6%) had a CIED infection. Four out of five patients required CIED extraction, while 1 patient antibiotics only. At multivariate Cox-regression analysis, age (hazard ratio [HR] 1.08; 95% confidence interval [CI] 1.05-1.10) and dialysis (HR 6.18; 95%CI 3.40-11.25) were independently associated with death, while first implant was associated with a lower risk as compared to subsequent procedures (HR 0.63; 95%CI 0.46-0.85) (Figure 1). CONCLUSIONS: In large contemporary cohort of CIED patients, mortality was substantially high and associated with clinical factors depicting a population at risk. On the other hand, the incidence of CIED infections was low. [Figure: see text]
