European study finds the CardioMEMS sensor results in improved quality of life and 44% reduction in heart failure hospitalizations
New data presented from an investigator-sponsored European trial found managing indicated1 heart failure patients with Abbott's CardioMEMS HF System resulted in a significant improvement in patient-reported quality-of-life scores as early as three months after use with the remote monitoring sensor The MONITOR-HF trial also resulted in a significant 44% reduction in heart failure-related hospitalizations among chronic heart failure patients who used guideline-directed medical therapy (GDMT)
GDMT refers to the European and U.S. guidelines for heart failure management that uses a combination of up to four heart medications. MONITOR-HF is the third randomized, controlled clinical trial globally to show a significant health benefit and quality-of-life improvement for heart failure patients using the CardioMEMS HF System.
The MONITOR-HF results were announced recently at a late-breaking presentation at the European Society of Cardiology's annual meeting of the Heart Failure Association in Prague and simultaneously published in The Lancet. The trial was funded by the Dutch Ministry of Health with clinical research organization costs paid by Abbott.
New Data Reveal Improved Quality of Life: The MONITOR-HF trial met its primary endpoint and found that heart failure participants who received a CardioMEMS sensor reported a clinically meaningful improvement in their quality-of-life as quantified by a 7-point mean increase on the Kansas City Cardiomyopathy Questionnaire's (KCCQ) score compared to patients in the control group, who did not receive the pressure sensor and whose scores decreased. In heart failure, the KCCQ is a clinical standard assessment that has been recommended to capture and measure patient-reported quality of care. The questionnaire4 asks patients how difficult it is to complete common activities such as walking a short distance, doing household chores and socializing with family and friends.
The CardioMEMS sensor is a paperclip-sized device that, once placed in the pulmonary artery during a minimally invasive procedure, monitors for pressure changes that indicate worsening heart failure. It wirelessly transmits daily readings to a patient's clinical team – empowering the patient and their care team to manage their condition from virtually anywhere.
About MONITOR-HF: MONITOR-HF is a prospective, randomized study with 348 patients enrolled in 25 centers in the Netherlands, representing one-third of the country's hospitals. Patients had New York Heart Association (NYHA) Class III heart failure with a previous heart failure-related admission or an urgent care visit requiring intravenous diuretics within the past year. Patients were randomly assigned to either hemodynamic monitoring using the Abbott CardioMEMS or the standard of care for heart failure management using GDMT. In the Netherlands, all participating sites had dedicated outpatient clinics where patients were seen at three months, six months, and every six months thereafter. Patients implanted with the Abbott CardioMEMS device were managed for at least one year and risk for complications remained low at 2.3%, which is consistent with previous investigations.
MONITOR-HF was designed and run by the Erasmus University Medical Center in Rotterdam, Netherlands. Abbott covered the clinical study costs with no part in the design, conduct of the study or any of its analyses.
The CardioMEMS sensor first received approval from the FDA in 2014 and the European Conformity (CE) mark in 2016.
