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 lead to
If successful, this could help doctors use renin levels to better manage blood pressure during heart surgery, potentially reducing complications.
