Heart failure can worsen long before symptoms become noticeable. Pulmonary artery pressure — the pressure of blood flowing from the heart to the lungs — can rise as heart failure worsens, often weeks before patients experience any symptoms. The CardioMEMS HF System, which has been shown to reduce heart failure hospitalizations2,3 and mortality risk4,5, measures pulmonary artery pressure through an implanted sensor in the pulmonary artery. For more than a decade, clinicians have used pulmonary artery pressure readings from the CardioMEMS HF System to help identify signs of worsening heart failure and guide treatment.
Building on that clinical experience with CardioMEMS, Abbott is continuing to evolve heart failure management with digital tools that help keep clinicians and patients connected between office visits. The CardioMEMS HF System with the CardioGuide HF App represents an important step toward helping patients take an earlier, more active role in understanding and managing their heart failure.
