Brain-Induced Neurotrophic Factor Levels in Patients Undergoing Coronary Artery Bypass Surgery

Although postoperative cognitive dysfunction (POKD) is the most common neurological complication in patients undergoing coronary artery bypass grafting (CABG) surgery, its pathophysiology is still not fully understood. However, the quality of this dysfunction has not been properly measured. In addition to clinical tests, biomarkers are often used to detect the presence of POKD. In this study, it was aimed to evaluate the relationship between intraoperative and postoperative brain-derived neurotrophic factor serum levels and POKD in patients undergoing CABG surgery.

This prospective observational study is planned to include 30 adult patients aged 40-90 years. Patients with stroke history, neurodegenerative disease, seizure history, alcohol use, general anxiety, hearing deficit, unilateral carotid artery stenosis greater than 70%, and carotid artery bilateral stenosis greater than 50% will be excluded from the study.

This study aimed to determine perioperative changes in serum brain-derived neurotrophic factor levels in patients undergoing CABG surgery.
