Tiny Lung-Artery sensor could help heart failure patients live longer
NCT ID NCT06306573
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study follows 2,500 people with moderate heart failure (NYHA Class II or III) who already have a CardioMEMS sensor implanted in their lung artery. The sensor wirelessly sends pressure readings to doctors, who use the data to adjust medications. Researchers will track survival over two years to see if using this real-time information helps patients live longer compared to a historical benchmark. The goal is to confirm the device's long-term safety and real-world effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CardioMEMS HF System (implantable wireless pressure sensor)
- What this could lead to
- If successful, this study could confirm that using real-time pressure data from inside the lung artery helps people with heart failure live longer and avoid hospital stays.
- What could go wrong
- This is an observational follow-up study, not a controlled trial, so it cannot prove cause and effect. The device itself carries risks like infection or sensor failure, and results may not apply to all heart failure patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Subject implanted with a CardioMEMS PA Sensor and enrolled in Merlin.net * Subject resides in the United States as documented in Merlin.net * NYHA Class II or Class III as documented in Merlin.net at the time of CardioMEMS implant (only NYHA Class II subjects contribute to the Primary Cohort) * Subject identified in Merlin.net data can be linked to Medicare FFS claims * Subject is enrolled in Medicare Part A and B, and not enrolled in Medicare Part C, at implant and for 12 months prior to implant, to establish qualification for CardioMEMS * Subject ≥18 years of age at time of CardioMEMS implant Exclusion Criteria: * Subject received heart transplant or durable mechanical circulatory support device implant (i.e., left/right/bi-ventricular assist device) prior to CardioMEMS implant
