0105 : Evaluation of management of heart failure and sleep apnea syndrome in a cardiac intensive care unit

Abstract

Sleep apnea syndrome (SAS) is seen in approximately 40% of patients with congestive heart failure. SAS is also associated with an increased mortality in patients with systolic heart failure. The aim of this work was to evaluate the screening for SAS in patients hospitalized for acute congestive heart failure in a cardiac intensive care unit. We performed a single-center retrospective study of patients hospitalized for congestive heart failure with altered left ventricular ejection fraction (lvef) ≤45% from june to december 2013. We assessed the screening for sleep apnea syndrom using Epworth sleepiness scale. We included 51 patients. Mean values were for age 76 y. o, men 54%, body mass index 27kg/m 2 , lvef 32%, diabetese 34%, hypertension 40%, NYHA III 38% and NYHA IV 50%. Only 14% (7) of patients were screened for SAS using the Epworth scale. All of them benefited a polysomnography at less one month after discharge. 6 of them (85%) were diagnosed with SAS. Although Epworth scale is a usefull and easy tool, Apnea syndrom remains underdiagnosed. Because of its high prevalence, poor outcome, and the beneficial effects of treatment, cardiologist should be more aware of SAS
