First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is checking how well the Dexcom G7, a continuous glucose monitor, works in 100 adults having heart surgery. The device is placed on the arm and tracks blood sugar during and after the operation for up to 10 days. The goal is to see if it gives accurate readings in this setting, which could help doctors manage patients' blood sugar more closely.

What this could lead to
If successful, this could show that the Dexcom G7 is reliable for managing blood sugar in cardiac surgery patients, potentially improving care.
What could go wrong
This is a small, early-stage accuracy study, not a treatment trial. The device may not perform as well in surgery as in other settings, and results may not apply to all patients.
