Abstract
PURPOSE
Galectin-3 is associated with myocardial fibrosis, a known risk factor for developing re-entrant circuits associated with atrial fibrillation (AF). Previous studies have demonstrated increased galectin levels in AF patients. Whether preoperative galectin-3 levels can predict the incidence of postoperative atrial fibrillation (POAF) remains unknown.
METHODS
This scoping review was conducted in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Electronic searches were conducted in Medline, EMBASE, Cochrane, and Google Scholar databases using a predetermined strategy. Methodological variables, demographics and operative data were extracted. Data extraction was performed manually by three reviewers.
RESULTS
The search yielded 620 citations, of which 74 underwent full text review, and 3 citations with 3 independent samples (n=1812) met full inclusion/exclusion criteria and were included. Of the three studies that reported on the association between preoperative galectin-3 levels and POAF, two studies compared median galectin levels in patients who developed POAF and those who did not. While Alexandre et al. reported a significant difference (p=0.002), Bening et al did not find a significant difference between POAF and non-POAF groups (p=0.3). A third study reporting on the association between galectin-3 and atrial fibrillation comparing 3rd and 1st tercile galectin-3 levels found a significant association between preoperative galectin levels and POAF on univariate analysis (OR 1.54; 95% CI 1.14-2.09).
CONCLUSIONS
Galectin-3 is an emerging biomarker that has been associated with the development of AF. However, there is currently not enough evidence to establish its prognostic role in post-cardiac surgery atrial fibrillation.
