Plasma galectin-3 was measured using a commercially available ELISA assay in patients with stable HF (n = 55), severe HF (n = 63), at 3 (n = 17) and 6 (n = 14) months post-LVAD and at LVAD explantation (n = 23), patients following HTx (n = 85) and healthy controls (n = 30). The gene discussed is LGALS3; the disease is hydrops fetalis.
