title: [Serum albumin and heart failure: recent advances on a new paradigm].
abstract: Hypoalbuminemia is a common condition in patients with heart failure and is mainly related to the malnutrition-inflammation complex syndrome. Other causal factors can be involved, which include hemodilution, liver dysfunction, increased transcapillary escape rate, renal and enteral loss. Evidence is growing that hypoalbuminemia independently predicts incident heart failure in patients with end-stage renal disease and elderly patients, as well as mortality in patients with heart failure regardless of left ventricular ejection fraction and clinical presentation. Hypoalbuminemia induces a low plasma oncotic pressure, which facilitates pulmonary edema in patients without critical increase in pulmonary capillary hydrostatic pressures. Hypoalbuminemia may also contribute to the progression of heart failure by favoring myocardial edema, volume overload, diuretic resistance and exacerbation of oxidative stress and inflammation. If relevant, removal of subclinical excess of fluid and renutrition may be indicated in patients with heart failure and hypoalbuminemia. Additional research is warranted to determine the specific role of serum albumin in the pathophysiologic process of heart failure and the potential benefits of targeted therapeutic interventions.
