Mortality and functional evolution at one year after hospital admission due to heart failure (HF) in elderly patients

The aim of this observational study was to describe the characteristics (including functional measures) of the elderly patients hospitalized in the acute geriatric unit (AGU) and diagnosed with HF as well as to determine the variables associated with mortality at one year after discharge. A prospective study including patients aged 70 and over hospitalized for acute decompensated HF was performed. The baseline measures were demographics, comorbidity, clinical, functional and cognitive status. The outcome for this study was death within one year from the index hospital admission date. During the length of the study, 32.7% patients died (20.7% within the first three months). The clinical features associated with HF-related mortality in the univariate analysis were institutionalization, a higher dependence in performing basic activities or instrumental activities of daily living (IADL). Older age did not correlate with mortality, nor did left ventricular hypertrophy (LVH), the ejection fraction or the pharmacological treatment at discharge. After performing the logistic regression analysis, the only variable independently related to a higher mortality risk at one year was the preadmission dependence in performing basic activities of daily living (BADL). The results of this study highlight that preadmission functional and sociodemographic variables are the best predictors of mortality at one year, surpassing the classic prognostic factors. Performing an adequate assessment at the time of admission, which should include a functional evaluation, may help us to better classify patients and to offer them a customized therapeutic plan with better prognostic capabilities.
