Study of Electrical Bioimpedance in Heart Failure.

12:58 EDT 24th July 2014 | BioPortfolio

Summary

The purpose of this study is to determine how electrical impedance is modified in relation to extracellular space body fluid retention detected by an electrical bioimpedance method in patients with heart failure.

Description

Heart failure (HF) is a clinical syndrome presenting currently a high prevalence, morbidity and mortality. The lack of sensitivity of symptoms and signs used to make the diagnosis of the exacerbation of HF, and the knowledge in recent years about the relevance to detect congestion before consulting a specialist or go to the emergency department, support the need of more aggressive management of these patients.

Bioimpedance monitoring devices for bioimpedance can provide useful data for the detection of congestion onset and help the decision-making in treatment.

Because patients with heart failure suffer alterations in body composition, mainly due to the amount of extracellular water, the bioimpedance can objectify these variations. In heart failure, bioimpedance has been tested in two studies with small samples of patients estimating total body water. In other studies , the monitoring of intrathoracic impedance has been performed by measurement systems implanted in cardiac defibrillators or in cardiac resynchronization devices. They have proven to be useful for early detection of decompensation in these patients and to detect changes in impedance before the patient begins the clinical manifestations. Furthermore, it has been correlated the detection of decompensation by these devices with significant increases in NT- proBNP (diagnostic and prognostic marker for HF).

The purpose of our study is to observe these changes in impedance from the patient's skin surface and non-invasively.

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 contraction during SYSTOLE leading to defective cardiac emptying.

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

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).
