Galectin-3 in Atrial Fibrillation

Galectin-3 is a other marker reported as elevated in Atrial Fibrillation when patients are compared with patients without atrial fibrillation (among those undergoing heart surgery). The source does not tie this marker to a specific symptom cluster, so it is best read as a biological signal rather than a symptom predictor. The evidence summarised here comes from Doulamis et al. 2019 and reflects averages across cohorts rather than any single patient's result.

Frequently asked questions

Is Galectin-3 high or low in Atrial Fibrillation?

Elevated. Studies summarised in the OSMF atlas report higher Galectin-3 in Atrial Fibrillation than in patients without atrial fibrillation (among those undergoing heart surgery). Source: Doulamis et al. 2019.

Which test measures Galectin-3?

The atlas record does not list a standardised clinical test code (LOINC) for Galectin-3, which usually means it was measured with research assays or study-specific protocols rather than a routine clinical panel. Check the cited source for the exact method.

Is one abnormal Galectin-3 result diagnostic of Atrial Fibrillation?

No. No single biomarker is diagnostic of Atrial Fibrillation. Galectin-3 findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
