Abstract

Transthoracic and whole-body bioimpedance monitoring has been commercially available for years; however, attention to its use as a diagnostic and event-monitoring modality has not been routinely applied in patients with heart failure (HF). In 2005, intrathoracic bioimpedance monitoring via an implantable cardioverter defibrillator brought new awareness of bioimpedance technology. In addition, new knowledge about congestion in HF, including length of time a patient is congested before seeking emergency care, lack of sensitivity of common signs and symptoms used to monitor congestion and diagnose HF exacerbation, and poor clinical outcomes when hypervolemia is present, heightened the need for more aggressive assessment and management. Bioimpedance device monitoring provides data needed to make treatment decisions that promote euvolemia and optimal cardiac performance. This review summarizes three options for measurement of bioimpedance hemodynamic data, discusses its use in preventing HF hospitalization, and describes issues that need to be overcome before bioimpedance monitoring can be routinely used in HF management.

There was a strong inverse correlation with intrathoracic impedance and pulmonary capillary wedge pressure and among intrathoracic impedance and net fluid loss during hospitalization with few false-positive detections.

This descriptive article provides an overview of tailoring therapies to congestive symptoms and reinforces why there is a need to measure hemodynamics in patient care. In this article, hemodynamic measurement is synonymous with pulmonary artery catheterization; however, the author recognizes that our tools are primitive and future research is needed.
