Abstract

Heart failure (HF) affects over 5.8 million patients in the United States, and can be very costly due to the number of hospitalizations and rehospitalizations during the final years of life. Due to the large number of hospitalizations for HF exacerbations, effective methods for preventing these occurrences are necessary. Improvements in the outpatient treatment of HF, aided by noninvasive and invasive home monitoring methods, can reduce the number of hospitalizations. Pulmonary pressure monitoring through the CardioMEMS system provides one method of hemodynamic assessment of patients. The efficacy of the CardioMEMS system in reducing the number of HF exacerbations has been explored in the CHAMPION trial (CardioMEMS Heart Sensor Allows Monitoring of Pressures to Improve Outcomes in NYHA Functional Class III Heart Failure Patients), which demonstrated a reduction in hospitalizations for HF exacerbations in patients whose medical management was guided by adjusting medications based on pulmonary pressures compared with clinical signs and symptoms. Retrospective analyses suggest that HF patients of certain subgroups, including those with left heart dysfunction and those with preserved left ventricular ejection fraction, could benefit from pulmonary pressure monitoring in controlling their HF. Larger studies are needed to determine whether mortality can be reduced with pulmonary pressure monitoring.
