Among them, vWF, TGF-β, and IL-8 levels demonstrated a positive correlation with PACs (r = 0.3, 95% CI [0.12–0.48], p < 0.001; r = 0.2, 95% CI [0.01–0.39], p = 0.03; r = 0.25, 95% CI [0.05–0.43], p < 0.001, respectively, Table 3). This evidence concerns the gene CXCL8 and Premature atrial contractions.
