Outcome of Patients with Advanced Heart Failure Who Receive Device-Based Therapy for Primary Prevention of Sudden Cardiac Death: Insights from the Israeli ICD Registry

BackgroundRandomized clinical trials have shown conflicting data on the benefit of implantable cardioverter defibrillator (ICD) for primary prevention of sudden cardiac death in patients with more advanced heart failure (HF) symptoms. Using the Israeli ICD Registry data, we sought to examine the effect of HF functional class on the outcome of patients who receive device therapy in a real-world setting.
