Expression of NDUFS1 (12.18 ± 0.83 vs. 32.01 ± 3.13[AU], p < 0.0001) and CPT1B (5.04 ± 0.74 vs. 15.36 ± 1.98[AU], p = 0.0006) mRNA was significantly reduced in LV tissue specimens of HF patients undergoing LVAD surgery compared to IVS EMBs of HTX patients with a normal LV function (Fig. 4e, f). This evidence concerns the gene NDUFS1 and hydrops fetalis.
