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.
