The CardioMEMS™ HF System is the first Food and Drug Administration (FDA)-approved heart failure (HF) monitor proven to significantly reduce HF hospital admissions and improve quality of life in NYHA class III patients.1 This implanted, wireless, battery-free device measures key vital signs, including pulmonary artery pressure in HF patients, and transmits this information remotely to the patient’s doctors for proactive management. The device was evaluated in 550 people in the CHAMPION (CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in NYHA Class III Patients) trial; Penn State Hershey Medical Center participated as an active enrolling center. During 15 months of follow-up, the treatment group had a 39 percent reduction in heart failure-related hospitalization compared with the control group.1
To participate, patients must have been hospitalized for HF in the 12 months prior. “That defines a relatively unstable population,” says John P. Boehmer, M.D., Penn State Hershey Heart and Vascular Institute. Once implanted, the CardioMEMS device requires patients to lie on a special mat every day. The mat includes an antenna that wirelessly connects and transmits data securely to a monitor that records 18 seconds of a pulmonary pressure tracing.
