Popis: Background : Patients with idiopathic dilated cardiomyopathy (DCM) receiving an ICD often improve their left ventricular dysfunction in the year following implantation due to reverse remodelling and/or optimization of concomitant drug therapy. We examined whether this improvement impacts the benefit of ICD in terms of appropriate therapy. Methods : The study comprised 93 consecutive DCM patients with LVEF 200 bpm or Results : Overall the mean LVEF increased by 7.2 % from 24.6±7% at baseline to 31.8±12% at revaluation. Two patterns were observed: 23 patients had a >14% LVEF increase (group 1) whereas 70 others had an increase Conclusions : In DCM, rhythmic risk is dynamic and inversely related to the improvement in LVEF. Reverse remodelling under optimal therapy is associated with a late favourable outcome, but 17% of these patients however benefit from ICD therapy in the early period.
