In the present study, we similarly detected the presence of IL-1β, IL-6, IL-8, TNF-α, and IL-10 in AF; the IL-6 values were lower, the TNF-α and IL-10 values were slightly higher, and the IL-1β and IL-8 values were comparable to the values reported in the previous studies. Here, CXCL8 is linked to atrial fibrillation.
