Objective:
To review the utility of galectin-3 (Gal-3) as a biomarker for postoperative adverse outcomes in patients undergoing cardiac surgery.
Method:
This review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic database search was conducted in October 2023. Studies that measured pre- and/or postoperative plasma Gal-3 levels in adult patients undergoing cardiac surgery were included. Primary outcomes included postoperative morbidity and mortality.
Results:
Out of 391 studies screened, eight studies met the inclusion criteria. Two of the three studies showed that preoperative plasma levels of Gal-3 were associated with acute kidney injury (AKI) after cardiac surgery. Two of the three studies reported a significant increase in preoperative Gal-3 levels in patients who developed postoperative atrial fibrillation (POAF). The addition of Gal-3 to the EuroSCORE II model was found to statistically improve the prediction of both AKI and POAF. Three of the five studies suggested that Gal-3 levels can predict postoperative mortality. Finally, one study suggested that lower preoperative Gal-3 levels was associated with a higher likelihood of achieving left ventricular reverse remodeling (LVRR) after surgery.
Conclusions:
Gal-3 may play a promising role in predicting adverse outcomes in patients undergoing cardiac surgery. The addition of Gal-3 to clinical risk prediction scores may improve their discriminatory power in this group of patients. Future studies are warranted to justify its incorporation into routine clinical practice.
