PREDICTING LONG-TERM SURVIVAL AFTER DE NOVO CARDIOVERTER DEFIBRILLATOR IMPLANTATION FOR PRIMARY PREVENTION

Abstract

Current guidelines recommend use of implantable cardioverter-defibrillators (ICDs) for the primary prevention of arrhythmia and sudden cardiac death in patients with reduced ejection fraction cardiomyopathy. While the mortality benefit of ICD insertion has been established in landmark randomized controlled trials, little is known about the long-term outcomes of patients with ICDs in clinical practice. We aimed to develop a risk prediction model for 10-year survival after ICD implantation for primary prevention.
