Serial galectin-3 and future cardiovascular disease in the general population

Posted by

Results Serial galectin-3 was measured in 5958 subjects (mean age 49±12 years; 49% female). The median duration of follow-up was 8.3 years. Persistently elevated galectin-3 (defined as highest quartile at baseline and highest quartile during visit 2, n=757 subjects) was associated with a higher risk for new-onset HF, CV mortality, all-cause mortality, new-onset atrial fibrillation and CV events, compared with subjects with non-persistently elevated galectin-3. After multivariable adjustments for baseline characteristics, serial galectin-3 remained an independent predictor of new-onset HF (HR 1.85 (1.10–3.13); p=0.02) but not for other outcomes. Serial measurements provided more accurate prognostic value to predict new-onset HF, compared with a single baseline measurement (Harrell’s C: 0.72 (0.68–0.75) vs 0.68 (0.65–0.72); p=0.002, respectively) with significant net reclassification.
