New patch could replace needles for monitoring heart patients
NCT ID NCT06597253
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new sensor worn on the skin that measures lactate levels without needles. It involves 20 adults recovering from heart bypass or valve surgery. The goal is to see if the sensor works as well as standard blood tests, which could make monitoring more comfortable and reduce the need for frequent blood draws.
