ABSTRACT
BACKGROUND:
The causes of hypoalbuminemia in patients with acute heart failure (HF) remain poorly defined, and the association between hypoalbuminemia and hospital and long-term mortality has been only partially evaluated. This study sought to analyze the causes of hypoalbuminemia in acute HF patients and determine its impact on hospital and long-term mortality. METHODS ANDRESULTS:
A total of 362 consecutive acute HF patients were assessed. The patients were divided into 2 groups according to the presence or absence of hypoalbuminemia (albumin ≤3.4 g/dL), and the independent association of each variable with hypoalbuminemia and hospital mortality was assessed with the use of multiple logistic regression. The association between hypoalbuminemia and long-term mortality was assessed with the use of Cox multivariate analysis. In total, 108 patients (29.8%) were classified as having hypoalbuminemia. Older age, higher C-reactive protein levels, and lower levels of total protein, prealbumin, transferrin, and lymphocytes were independently associated with hypoalbuminemia. Hospital mortality was 8% and was independently associated with hypoalbuminemia. A total of 333 patients were discharged. Hypoalbuminemia was an independent predictor of mortality.CONCLUSIONS:
Hypoalbuminemia in acute HF patients was associated with higher hospital mortality and served as an independent predictor of long-term mortality. Malnutrition and inflammation were factors causing hypoalbuminemia in this clinical setting.Palabras clave
