Within the subgroup with preserved LVEF (n = 22), those with conduction disorders (n = 10) exhibited higher levels of IL-10 (24.49 vs. 9.83 pg/mL; q = 0.009), IL-12p70 (13.20 vs. 9.02 pg/mL; q = 0.027), IL-2 (2.70 vs. 2.07 pg/mL; q = 0.023), IL-15 (7.09 vs. 3.36 pg/mL; q = 0.018), MIP1α (10.33 vs. 3.35 pg/mL; q = 0.014) and IFN-γ (10.83 vs. 7.25 pg/mL; q = 0.005), compared to those without conduction disorders (n = 12). This evidence concerns the gene CCL3 and conduction system disorder.
