ZOLL Heart Failure Management System


BMAD Trial Results:
Reduce Readmission and Improve Outcomes with ZOLL HFMS

The Benefits of MicroCor in Ambulatory Decompensated Heart Failure (BMAD) Trial demonstrated the impact of utilizing ZOLL® Heart Failure Management System* (HFMS) for fluid management following an acute decompensation event.1

Intervene Before HF Readmission with ZOLL HFMS: A Physician's Perspective

Invasive cardiologist, Dr. Fahmi J. Farah, MD, and one of her patients share how ZOLL HFMS impacts heat failure treatment and readmission rates.


Early Pulmonary Fluid Detection and Improved Outcomes

Pulmonary fluid can accumulate days before patients experience noticeable symptoms, and can be an early indicator of a heart failure decompensation event.5

Pathophysiology of decompensation chart


ZOLL HFMS is a non-invasive, patch-based device that uses novel radiofrequency technology for early detection of changes in pulmonary fluid levels, an increase in which is an early indicator of heart failure decompensation.

  • Radar waves can be used to measure interstitial edema, an early sign of heart failure
  • Changes in signal path delay and strength indicate changes in fluid
  • Waves are highly modulated by tissue hydration, producing a very sensitive, robust measurement known as Thoracic Fluid Index (TFI)

ZOLL HFMS also records, stores, and transmits additional patient data that can be used to inform care plans, including heart rate, respiration rate, activity, posture, and heart rhythm (ECG).

Heart Failure on the Rise

Heart failure is one of the largest clinical challenges facing healthcare, affecting nearly 6 million Americans, as reported in 2020.6 The current U.S. expenditure for heart failure exceeds $30 billion annually, with 60-80 percent related to hospitalization, and these figures are expected to grow in the future.7

Support for You and Your Patients

From prescription to timely alerts, ZOLL supports every step of the process so that your team can focus on optimizing care and improving outcomes.

ZOLL HFMS may benefit patients who:

  • Have had an acute event for volume overload and have been effectively diuresed, are now stable, and will benefit from remote pulmonary fluid management to predictively prevent a recurrent hospitalization
  • Have intermittent and/or poorly controlled dyspnea, orthopnea, edema, or other fluid overload-related symptoms
  • Require GDMT pharmaceutical titration to control fluid overload
