Abstract:
AIMS:Calcium channel plays an important role in the autoimmune pathogenesis of idiopathic dilated cardiomyopathy (DCM). Autoantibodies have emerged as a new upstream target of sudden death in DCM. We sought to validate the hypothesis that autoantibodies against l-type calcium channel (CC-AAbs) are arrhythmogenic and lead to sudden death in patients with DCM. METHODS AND RESULTS:We investigated sudden death and ventricular arrhythmias in 80 patients with DCM in a prospective, case follow-up survey. During a follow-up of 32 (SD 8) months, CC-AAbs-positive patients not only had a higher incidence of ventricular tachycardia (VT) but also a higher incidence of sudden death than CC-AAbs-negative patients (for VT: 59.0 vs. 24.4%, P = 0.002 and for sudden death: 20.5 vs. 4.9%, P = 0.045). Further univariate and multivariate analyses showed that the occurrence of CC-AAbs was the strongest independent predictor for sudden death (odds ratio: 10.20, 95% confidence interval: 2.43-36.78, P = 0.0027). Experimental studies in ex vivo systems using affinity-purified CC-AAbs from patients demonstrated that CC-AAbs were able to induce VT by prolongation of action potential duration (APD) and triggered activity by early afterdepolarization (EAD). CONCLUSION:Our results demonstrate for the first time to our knowledge that there is a high incidence of sudden death and VT in CC-AAbs-positive patients with DCM. Furthermore, experimental data from ex vivo systems suggest that CC-AAbs might induce VT by prolongation of APD and triggered activity by EAD.
