Abstract
BACKGROUND
Acute decompensated heart failure (ADHF) is the main cause of hospitalization and death of octogenarians, but no data on the 1-year post-discharge mortality rate. We evaluated the clinical status and predictors of 1-year mortality in octogenarians with ADHF.
METHODS AND RESULTS
From the AURORA (Acute Heart Failure Registry in Osaka Rosai Hospital) study, we examined 1,246 hospitalized ADHF patients. We compared the in-hospital mortality rate and the proportion of heart failure (HF) with preserved ejection fraction (HFpEF) between octogenarians and non-octogenarians. After discharge we compared the 1-year mortality rate between these groups, and we also evaluated the predictors of death in both groups. The proportion of HFpEF among the in-hospital deaths of octogenarians was significantly higher than in non-octogenarians (46.2% vs. 15.0%, P=0.031). The 1-year mortality rate after discharge was significantly higher in the octogenarians than non-octogenarians (P=0.014). Multivariable Cox regression analysis revealed that albumin ≤3.0 g/dL and antiplatelet agents were useful predictors of 1-year death after discharge of octogenarians whereas chronic kidney disease was a predictor in the non-octogenarians.
CONCLUSIONS
The proportion of HFpEF among in-hospital deaths of octogenarians with ADHF was high as compared with non-octogenarians. When octogenarians with ADHF have severe hypoalbuminemia and antiplatelet agents, early nutritional and medical interventions after discharge may be important to improve the 1-year prognosis.
