Fluid and Salt Restriction in Decompensated Heart Failure Patients

2014-08-27 03:13:20 | BioPortfolio


The non-pharmacological measures that are widely practiced and recommended for HF patients, such as salt and water restriction, specially at moments of disease decompensation, still lack clearer evidence of their therapeutic effect.


Heart Failure Clinics, healthcare structures formed by a multidisciplinary team specialized in the disease, have demonstrated to provide benefits to patients through multiple non-pharmacological interventions, among them fluid and salt restriction. Sodium restriction has a class I recommendation and evidence level C, that is, general agreement that the intervention is beneficial, useful and effective, evidenced by consensus, expert opinion, small studies, retrospective studies or registries. Sodium restriction becomes even more controversial when we consider evidence suggesting the benefit of non-salt restriction or treatments with salt administration, in the form of hypertonic solutions. In face of literature evidence not showing conclusive results about the benefit of sodium and fluid restriction, we designed this study in order to assess the effect of fluid and salt restriction on the management of patients hospitalized due to decompensated heart failure

Medical and Biotech [MESH] Definitions

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.

Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.

Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
