Abstract
BACKGROUND: Administrative data show that acute heart failure (HF) patients are older than those enrolled in clinical registries and frequently admitted to non-cardiological settings of care. The purpose of this study was to describe clinical characteristics of old patients hospitalised for acute HF in Cardiology, Internal Medicine or Geriatrics wards. METHODS: Data came from ATHENA (AcuTe Heart failurE in advaNced Age) registry which included elderly patients (≥ 65 years) admitted to the above mentioned settings of care from December 1, 2014 to December 1, 2015. RESULTS: We enrolled 396 patients, 15.4% assigned to Cardiology, 69.7% to Internal Medicine, and 14.9% to a Geriatrics ward. Mean age was 83.5 ± 7.6 years (51.8% of patients ≥ 85 years) and was higher in patients admitted to Geriatrics (P < 0.001); more than half were females. Medical treatments did not differ significantly among settings of care (in a context of a low prescription rate of renin-angiotensin-aldosterone system inhibitors) whereas significant differences were observed in comorbidity patterns and management guidelines recommendation adherence for decongestion evaluation with comparison of weight and N-terminal pro-B-type natriuretic peptide levels on admission and at discharge (both P = 0.035 and P < 0.001), echocardiographic evaluation ( P < 0.001) and follow-up visits planning ( P < 0.001), all higher in Cardiology. Mean in-hospital length of stay was 9 ± 5.9 days, significantly higher in Geriatrics (13.7 ± 6.5 days) and Cardiology (9.9 ± 6.7 days) compared to Internal Medicine (8 ± 5.2 days), P < 0.001. In-hospital mortality was 9.3%, resulting higher in Geriatrics (18.6%) and Cardiology (16.4%) than Internal Medicine (5.8%), P = 0.001. CONCLUSIONS: In elderly patients hospitalised for acute HF, clinical characteristics and management differ significantly according to the setting of admission.
