Rusnak J, Behnes M, Weiß C, et al. - Researchers assessed how left ventricular ejection fraction (LVEF) could influence recurrences of ventricular tachyarrhythmias among recipients of implantable cardioverter defibrillator (ICD). They utilized a large retrospective registry which involved all consecutive ICD recipients with episodes of ventricular tachycardia or fibrillation from 2002 to 2016. They performed a comparison between patients with LVEF < 35% and those with LVEF ≥ 35%. This analysis involved 528 consecutive ICD recipients. Findings revealed the link of LVEF < 35% with reduced freedom from recurrent ventricular tachyarrhythmias, appropriate device therapies, rehospitalization and all-cause death secondary to index ventricular tachyarrhythmias.
