Since other studies found a role for TNF in ventricular and electrical function in CCC (36), and since TNF, IL-1β, and IL-6 are often involved in ventricular tachycardia (37–39), we believe the focus of future studies should be to simultaneously target TNF, IL-6, and IL-1β (40) in order to assess the role of these usually cooperative cytokines in CCC. This evidence concerns the gene TNF and ventricular tachycardia.
