Remote Physiologic Monitoring for Heart Failure.

PURPOSE OF REVIEW

This review will describe the process of remote monitoring in the treatment of heart failure and the clinical trials for different modalities of data collection.

RECENT FINDINGS

Small studies monitoring weights, sometimes with other parameters, suggested a significant outcome benefit in meta-analysis. However, this has not been seen in larger studies. Clinical trials of remote monitoring using hemodynamic parameters seems to lead to improved outcomes, with more studies underway. Recently, multi-parameter methods with wearable or implantable devices have shown promise in detecting heart failure. The impact on clinical outcomes is being assessed. When using parameters such as daily weights, remote monitoring for heart failure has not been demonstrated to be broadly beneficial, while remote monitoring of hemodynamic parameters to guide heart failure therapy has met with initial success. Methods of combining multiple physiologic measurements appear to accurately detect worsening heart failure, and clinical trials are underway to assess the impact.
