Correlation between S100A9 and cardiac events. (a) S100A9 expression was measured at admission before, 0, and 12 H after PCI in patients with AMI(n = 16). (b) S100A9 expression was upregulated in patients developing MIRI(n = 22) compared with those who did not(n = 30). (c) Among patients with MIRI, S100A9 expression was higher in CNR(n = 9) compared to those without CNR(n = 13). (d-g) Spearman Correlation in AMI patients Between Expression Levels of S100A9 and LVEF (d), gensini score (e), neutrophils percentage (f), and White blood cell counts (g). * P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
