Totally automated blood pressure monitoring at home to improve care of patients with Heart Failure or Pulmonary Hypertension.

A permanent pressure sensor implanted in the heart’s pulmonary artery lets patients with heart failure or pulmonary hypertension monitor their condition daily from home, replacing risky and expensive hospital catheterisations. Current treatment for chronic heart failure relies on drugs like diuretics and beta-blockers, but individual responses vary widely. Patients require frequent clinical reviews to adjust doses, and when stability fails, they are re-hospitalised—a pattern linked to high mortality. The most reliable measure of disease control, pulmonary artery pressure, currently requires cardiac catheterisation, an invasive procedure too risky and costly to repeat often. This project proposes placing a permanent pressure-sensing implant during the first catheterisation, then transmitting pressure readings wirelessly via a mobile health link while the patient goes about normal activities. If successful, the implant would give patients immediate warning of deteriorating condition, allowing faster treatment adjustments and fewer hospital admissions. Clinicians would gain continuous, dynamic pressure data—far more informative than a single reading taken in a hospital bed. For the health service, this could mean fewer consultations, fewer invasive procedures, and more precise drug titration. The technology also creates an unprecedented tool for assessing how different treatments affect real-world patient responses.
