Szczegółowy opis
This is a prospective observational cohort study of patients undergoing off-pump coronary artery bypass grafting. The study aims to investigate postoperative cognitive dysfunction and its association with perioperative clinical factors. Eligible patients will be enrolled before surgery and followed after surgery according to the study protocol.
Baseline information will be collected before surgery, including demographic characteristics, medical history, comorbidities, laboratory test results, and preoperative cognitive assessment. Intraoperative and postoperative data will also be collected, including anesthesia-related variables, surgical information, hemodynamic and monitoring parameters, postoperative clinical status, and relevant complications.
Cognitive function will be assessed before surgery and at predefined postoperative time points using standardized cognitive assessment tools, such as the Montreal Cognitive Assessment. Postoperative cognitive dysfunction will be determined according to the predefined criteria based on changes in cognitive assessment results from baseline to postoperative follow-up.
The study will describe the incidence of postoperative cognitive dysfunction after off-pump coronary artery bypass grafting and evaluate the association between perioperative factors and postoperative cognitive outcomes. The results may help improve understanding of postoperative cognitive dysfunction in this surgical population and provide evidence for perioperative risk assessment and clinical management.

Off-Pump Coronary Artery Bypass Grafting Cohort
Patients undergoing off-pump coronary artery bypass grafting who will receive preoperative cognitive assessment and postoperative follow-up for postoperative cognitive dysfunction.
Perioperative clinical information, including preoperative assessment data, intraoperative monitoring parameters, and postoperative clinical data, will be collected.
|
Off-pump coronary artery bypass grafting is performed as part of routine clinical care for patients with coronary artery disease.
The study protocol does not assign participants to this procedure or to any additional intervention.
This observational study will collect perioperative clinical data and follow patients after surgery to assess postoperative cognitive dysfunction.

Incidence of Postoperative Cognitive Dysfunction
Ramy czasowe: Postoperative Day 7, or 1 Day Before Hospital Discharge if Discharged Before Postoperative Day 7
|
Postoperative cognitive dysfunction will be evaluated by comparing postoperative Montreal Cognitive Assessment scores with preoperative baseline scores.
Preoperative cognitive function will be assessed using the Montreal Cognitive Assessment 1 day after hospital admission.
Postoperative cognitive function will be assessed using the Montreal Cognitive Assessment on postoperative day 7 or, if the patient is discharged before postoperative day 7, 1 day before hospital discharge.
Postoperative cognitive dysfunction is defined as a decline in the postoperative Montreal Cognitive Assessment score of at least 1 standard deviation compared with the preoperative baseline score.
