Objective
Although digoxin improves heart failure symptoms, its potential proarrhythmic effects on ischemic myocardium has been debated. In this cross-sectional study, we investigated the relation between appropriate shocks in patients with ischemic heart failure (HF) and implantable cardioverter defibrillator (ICD).
Results
A total of 139 patients were included in the present study. Of these 35 patients (25.1%) experienced appropriate ICD shocks. In patients with ICD shocks, baseline left ventricular ejection fraction (LVEF) was significantly lower (p=0.009). When patients were compared according to the medications used, the number of the patients using aspirin and diuretic was significantly higher in the shock-received group whereas, statin usage was significantly lower in the shock-received group (p=0.030, p=0.046, p=0.044; respectively). Digoxin usage did not differ between the groups (p=0,388). In logistic regression analysis, aspirin usage and LVEF were found as independent predictors of ICD shocks (p=0.032 and p=0.045).
