SLC2A3 and hydrops fetalis: Interestingly, except for SLC2A3, seven (n = 7) of the hub genes in patients with post-STEMI HF were observed upregulated on the first day of STEMI (admission), especially BST1 and ITGAM with significance, as compared with those who also presented with STEMI on admission but did not progress to HF during the 6 months of follow-up (Figures 6A–H).
