We studied 592 HFpatients who had been hospitalized for HFand were followed
for 18 months. The primary end-point was a composite of all-cause mortality and
HF hospitalization. A doubling of galectin-3 levels was associated with a hazard
ratio (HR) of 1.97 (1.62–2.42) for the primary outcome (P = 0.001). After
correction for age, gender, BNP, eGFR, and diabetes the HR was 1.38 (1.07–
1.78; P = 0.015). Galectin-3 levels were correlated with higher IL-6 and CRP
levels (P = 0.002). Changes of galectin-3 levels after 6 months did not add
prognostic information to the base-line value (n = 291); however, combining
plasma galectin-3 and BNP levels increased prognostic value over either
biomarker alone (ROC analysis, P = 0.05). The predictive value of galectin-3
was stronger in patients with preserved LVEF (n = 114) compared to
patients with reduced LVEF (P = 0.001).

Galectin-3 is a soluble ß-galactoside-binding lectin released by activated
cardiac macrophages. Elevated levels of galectin-3 have been found to
be associated with adverse outcomes in patients with heart failure. We
evaluated the association between galectin-3 and long-term clinical
outcomes in ambulatory heart failure patients enrolled in the HF-ACTION
study.
Galectin-3 is elevated in ambulatory heart failure patients and is
associated with poor functional capacity and other known measures of
heart failure severity. In univariate analysis, galectin-3 was significantly
predictive of long-term outcomes, but this association did not
persist after adjustment for other predictors, especially NTproBNP.
