[Infective endocarditis : In-hospital mortality predictive factors]

Abstract

Introduction: Infective endocarditis (IE) remains a serious disease with significant morbidity and mortality despite therapeutic advancements. The aim of our study was to determine the predictive factors of in-hospital mortality.

Patients and methods: A prospective comparative study over a period of 54 months was conducted, including all patients admitted for definite infective endocarditis, diagnosed according to the modified Duke criteria published in 2015 by the European Society of Cardiology.

Results: Thirty-four patients were included. Drug addiction was the main risk factor for infective endocarditis (56%). Tricuspid valve involvement was predominant (50%). Staphylococcus aureus was the most commonly isolated pathogen (65%). In-hospital mortality rate was 47%. In multivariate analysis, predictive factors for mortality were acute heart failure (OR=7.4; p=0.026; 95% CI [1.2-44]) and cerebral embolic localization (OR=11.1; p=0.024; 95% CI [13-90]).

Conclusions: Cardiac and cerebral complications influence the prognosis of IE. Thus, close collaboration among multidisciplinary teams is necessary for improved diagnostic and therapeutic management.
