    Abstract:
    OBJECTIVE: To determine the characteristics of elderly persons hospitalized for congestive heart failure and identify the factors associated with functional impairment or death at discharge and 3 months later. MATERIAL AND METHODS: We performed a prospective observational study that included 162 patients admitted to an Acute Geriatric Care Unit with a diagnosis of heart failure from February to July 2007. Socio-demographic, clinical, functional and cognitive factors were recorded during admission. Functional and vital measurements were reported at discharge and 3 months later. RESULTS: The incidence of mortality or functional decline was 48.8% at discharge and was 37.3% 3 months later. In the final model, predictors of functional impairment or mortality at discharge were days of hospital stay and a worse Pfeiffer test score (odds ratio [OR]: 1.74; 95% confidence interval [CI]: 1.33-2.29). Three months after discharge, independent prognostic factors were age (OR: 1.09; 95% CI: 1.02-1.17), hyponatremia (OR: 0.85; 95% CI: 0.77-0.94), length of QRS in milliseconds (OR: 0.98; 95% CI: 0.97-0.99), absence of ventricular hypertrophy (OR: 0.42; 95% CI: 0.19-0.94), and a poor result in the Pfeiffer Test (OR: 1.40; 95% CI: 1.13-1.73). CONCLUSIONS: Cognitive evaluation during hospital admission for heart failure in the elderly helps to select individuals at risk of functional impairment or death at discharge and 3 months later.
