NCT ID NCT06895213
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study at Mayo Clinic looks at how renin, a protein in the blood, changes when patients are on the heart-lung machine during open heart surgery. Researchers want to see if renin levels can help guide treatments for low blood pressure. The study will enroll 100 adults having elective heart surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors use renin levels to better manage blood pressure during heart surgery, potentially reducing complications.
What could go wrong
This is an early observational study with only 100 participants. It is not testing a treatment, so it may not lead to any direct changes in care.
