Differential clinical characteristics and outcome predictors of acute heart failure in elderly patients
2012
Abstract Objective We determined the clinical-epidemiological characteristics and prognostic factors of early mortality and re-consultation in an elderly population attending the hospital emergency department (HED) for acute heart failure (AHF). Patients and methods A prospective, observational, non interventional study including all the patients with AHF attended in the Spanish's HED. Two groups were defined: elderly (≥80years) and controls ( Results Of the 942 patients included, 455 of whom were elderly (48.3%). In this elderly population female sex, auricular fibrillation and a history of ictus and a poor functional status predominated. The type of ventricular dysfunction was unknown in 70%. No main differences in the presentation of AHF were found between the two groups. Mortality and re-consultation to the HED within 30days were similar in both groups. While several factors were identified to be related to mortality or re-consultation in control group, in the elderly group it was more difficult to identify patients who will die or re-consult to the HED within the following 30days. Only respiratory insufficiency on arrival to the HED was found to predict a greater probability of death (OR 3.55; CI95% 1.39–9.11). Conclusions AHF in elderly patients presents some differential characteristics and, most importantly, it is more difficult to identify which of these patients will die or re-consult in the short-term.
