LGALS3 and hydrops fetalis: Likewise, GAL-3 was elevated in both HF with preserved left ventricular ejection fraction (23±9 ng/mL) and HF with reduced left ventricular ejection fraction (22±11 ng/mL) (P<0.001 versus controls for both) but did not differ between HF with preserved ejection fraction and HF with reduced ejection fraction (P=0.37).
