The National Institute for Health and Care Excellence (NICE) has recommended the CardioMEMS HF wireless sensor for home monitoring of patients with chronic heart failure. The paper clip-sized system is implanted in the pulmonary artery through a right heart catheterization procedure. Patients measure the pressure in the pulmonary artery daily while lying on a special pillow at home. The measured values are sent wirelessly to the patient's hospital team. This allows early recognition of warning signs and adjustment of medication before symptoms worsen. The NICE decision is based on three randomized controlled trials that showed a 34% reduction in heart failure hospitalizations compared to usual care. The technology is recommended for remote monitoring of adults with chronic heart failure as classified by the New York Heart Association (NYHA).
