Annual mortality in population of patients undergoing cardiac implantable electronic device insertion: Retrospective observational study

Abstract

Abstract Introduction: There is a group of CIED inserted patients with poor outcome. It is advisable to identify the population whose state of health immediately before the procedure is an additional risk factor for an unfavorable clinical course, because it may improve the prognosis and quality of patient care. Objectives: The aim of the study was the isolation of risk factors for one-year mortality after the insertion of an electrotherapy device. Patients and methods: This study is a retrospective analysis of medical records of consecutive patients operated on in the Electrophysiology Laboratory of the Cardiology Department of the Western Hospital in Grodzisk Mazowiecki (n = 477). Death within a year after the procedure of CIED insertion was established as the endpoint. The analysis included factors related to the procedure, clinical condition, course of hospitalization, and results of selected laboratory tests. Statistical analysis was performed using PQStat, version 1.6.8. Results: Sixty-seven people died within a year of the procedure, which is 14.04% of the study population (n = 477). The multivariate logistic regression model revealed an independent risk factor for death within the first year after the procedure was CRP >10 mg/l (OR 4.01, 95% CI: 1.92–8.37, p <0.001). Conclusions: CRP concentrations >10 mg/L on admission were the main determinant of the endpoint regardless of comorbidities and periprocedural complications. CRP admission concentrations should be addressed during periprocedural management, because this may reduce mortality.
