Primary Outcome Measures:
  • To identify if electrical bioimpedance analysis is useful for diagnosis, monitoring and prognosis in patients with heart failure. [ Time Frame: 18 months ]

Secondary Outcome Measures:
  • To analyze segmental and whole-body bioimpedance measures in a population of heart failure patients with multi frequency body composition analysis [ Time Frame: 18 months ]
  • To study the relation between electrical bioimpedance changes with patients' clinical situation (compensated versus decompensated HF) [ Time Frame: 18 months ]
  • To assess potential correlations between impedance, clinical status, heart failure functional class, and NT-proBNP. [ Time Frame: 18 months ]

Blood serum obtained from routine blood test

Estimated Enrollment: 400
Study Start Date: April 2009

Detailed 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.
