The Impact of New-onset Atrial Fibrillation on Short-term and Long-term Mortality of Critically ill Patients with Candidemia

Abstract Background Both new-onset atrial fibrillation (NOAF) and candidemia occurred frequently in critically ill patients, which are associated with poor outcomes. But, the association between NOAF and critically ill patients with candidemia is still uncertain. This study is try to identify the impact of NOAF on short-term and long-term mortality of critically ill patients with candidemia. Methods We retrospectively identified NOAF in all patients with candidemia admitted to a non-cardiac intensive care unit (ICU) from January 2011 to March 2018 in a teaching hospital. We categorized these patients into 3 groups (NOAF, Prior AF, No AF) and compared clinical information between groups. Risk factors for these patients’ short-term and long-term mortality were also analyzed. Results Ninety-two patients with candidemia were identified from 2011 to 2018. Among these patients, 26 (28.3%) developed NOAF during their hospital stay. The multivariable logistic regression analysis indicated that stroke, anemia, Sequential Organ Failure Assessment (SOFA) score and NOAF were independent risk factors for in-hospital mortality and NOAF was also the independent risk factor for 1 year mortality. Conclusions There was a high incidence of NOAF in critically ill patients with candidemia, which was associated with in-hospital mortality and 1 year mortality after hospital discharge. Further multicenter studies should be conducted to help confirm this relationship and to find effective interventions that reduce short-term and long-term mortality.
