Selvester score predicts implantable cardioverter defibrillator shocks in patients with non‐ischemic cardiomyopathy

Description
Summary:Background The implantable cardiac defibrillator is the cornerstone of prevention of sudden cardiac death in non‐ischemic cardiomyopathy. The Selvester score, which is frequently investigated in ischemic cardiomyopathy, has not been investigated in the field of non‐ischemic cardiomyopathy. Aim The aim of this study was to evaluate the Selvester score for determining appropriate implantable cardiac defibrillator shocks in non‐ischemic cardiomyopathy patients. Materials and methods In all, 131 non‐ischemic cardiomyopathy patients were included in the study. A simplified Selvester score was calculated from ECG data. Patients were divided into two groups according to whether they received ICD shock. Results Of the patients, 28.2% received appropriate implantable cardiac defibrillator shock. The Selvester score was significantly higher in patients receiving appropriate shock when compared to patients with no implantable cardiac defibrillator shocks (8.8 ± 4.6 vs 7.2 ± 3.3, P = .040). The median QRS duration was significantly longer in patients receiving appropriate shock than in patients with no shocks (130.14 ± 35.08 ms vs 120.12 ± 20.57 ms, P = .045). We determined that the cutoff value for the Selvester score to predict ICD shocks was 6.5 with a sensitivity of 72.0% and a specificity of 83% (AUC = 0.717; %95 GA: 0.627‐0.807, P
