The levels of LOX-1 (31.67 ± 4.23 vs. 38.01 ± 3.98), hs-cTnT (133.54 ± 12.79 vs. 158.21 ± 15.62), and NGAL (18.76 ± 3.21 vs. 24.08 ± 4.56) in patients with mild renal dysfunction were lower than those in patients with severe renal dysfunction, with statistically significant differences (P < 0.05) (Table 2). The gene discussed is LCN2; the disease is Abnormal renal physiology.
