Background Patients aged 85 years or older admitted for heart failure (HF) have increased enormously due to improved survival in this disease. However, few studies assess the characteristics, treatments, and prognosis of very elderly patients admitted for acute HF. Methods This study is a retrospective analysis of the EPICTER registry, that included patients admitted for acute HF in 74 Spanish hospitals. For this analysis, a total of 1887 patients were included and divided into 2 groups: 85 years or older (very elderly, 680 patients) and those under 85 years. Results Compared to patients < 85 years, very elderly patients were more frequently women, had more hypertension and disease cerebrovascular disease, and less presence of chronic obstructive pulmonary disease (COPD), diabetes, and acute myocardial infarction. There were no differences in symptoms, except for delirium, significantly more common in very elderly patients. Management of these patients was more conservative and died more than the younger ones (41% vs. 25%, P < 0.001). The predictor variables of mortality in very elderly patients were the presence of COPD and peripheral arterial disease, delirium, and estimated survival of less than 6 months assessed by the physician in charge of the patient care. Conclusion Very elderly patients admitted for HF differ from younger ones in comorbidities, management, and symptoms, and have higher mortality. The presence of delirium, peripheral arterial disease, and COPD worsen the prognosis in these patients and can help to adapt the therapeutic effort and place emphasis on adequate symptom control.
