Nerve damage linked to kidney trouble in bypass patients
NCT ID NCT07254468
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a nerve condition called cardiovascular autonomic neuropathy (CAN) affects the risk of kidney injury in people having heart bypass surgery. Researchers tracked 912 adults before, during, and after surgery to see if those with CAN had worse kidney function or other complications. The goal was to better understand these risks, not to test a new treatment.

Who is studied
This study includes adult patients (≥18 years old) scheduled for elective isolated Coronary Artery Bypass Graft (CABG) surgery with planned extracorporeal circulation (ECC). Participants will be evaluated preoperatively for cardiovascular autonomic neuropathy (CAN) using standardized tests. Patients with chronic kidney failure, severe chronic respiratory disease, uncontrolled hypertension, or conditions preventing autonomic testing are excluded. Both male and female adults are eligible, and all participants must provide informed consent.
