Predictive Value of Postoperative Prognostic Nutritional Index Trajectory on 1-year Mortality After Off-pump Coronary Artery Bypass Surgery

Predictive Value of Postoperative Prognostic Nutritional Index Trajectory on 1-year Mortality After Off-pump Coronary Artery Bypass Surgery

This study investigated the changing pattern of postoperative Prognostic Nutritional Index (PNI) after off-pump coronary artery bypass surgery using a trajectory analysis. The investigators aimed to investigate the correlation between postoperative PNI recovery patterns and mortality in patients undergoing off-pump coronary artery bypass surgery.

Inclusion Criteria:

• Patients aged ≥ 18 years who underwent off-pump coronary artery bypass surgery

Exclusion Criteria:

• Patients without PNI value between 1 and 3 days after surgery
• Patients without PNI value between 20 and 60 days after surgery
