PROACTIVELY MANAGING PRESSURE
Changes in PA pressure occur early on in the progression toward cardiac decompensation, and are a direct indicator of worsening heart failure. Early changes can often be addressed through titration of medications—reducing the need for hospitalization, and averting serious progression and complication. Small changes early in this process make a big difference, and the CardioMEMS HF System enables a proactive approach to patient care.
TRADITIONAL MARKERS PROVEN TO NOT IMPROVE OUTCOMES
In large randomized controlled studies (TELE-HF, TIM-HF), daily telemonitoring of symptoms, blood pressure and/or weight did not reduce hospitalizations or deaths.2,3
PA PRESSURE MONITORING WITH THE CARDIOMEMS™ HF SYSTEM
Evidence shows CardioMEMS HF System provides:
- Significant reductions in heart failure hospitalizations in patients with preserved or reduced ejection fraction6,7,8
- Hospitalization reduced by 1/3 at 18 month6
- Shorter length of patient stay when hospitalized6
- Better patient quality of life (5 point difference in Minnesota Living with Heart Failure Questionnaire)6

HOW THE CARDIOMEMS™ HF SYSTEM WORKS
Monitoring PA Pressure
The CardioMEMS™ HF System provides ambulatory pulmonary artery (PA) pressure monitoring using a small pressure sensor, permanently implanted in the distal pulmonary artery via a safe right heart catheterization procedure.
Patient-initiated sensor readings are wirelessly transmitted to an external electronics unit and stored in a secure website for clinicians to access and review. Directly monitoring PA pressure not only alerts you if a patient’s heart failure is worsening, but allows you to intervene earlier, adjusting medication or making other treatment changes.
BUILDING COMPREHENSIVE HEART FAILURE MANAGEMENT
The CardioMEMS™ HF System is an integral part of our heart failure management portfolio. Our vision is to transform the treatment of heart failure by designing best-in-class, integrated technology to extend and improve lives while decreasing the burden of care and reducing costs.
