Meanwhile, in the serum of HF patients, the expression of several inflammatory cytokines appeared substantially elevated, including tumor necrosis factor‐α (TNF‐α), interleukin‐6 (IL‐6), interleukin‐1b (IL‐1b), soluble suppression of tumorigenicity‐2(sST2), and Galectin‐3(Gal‐3) (Figure 1D–H). Here, LGALS3 is linked to hydrops fetalis.
