Study context

Population
Patients with heart failure (HF) (reduced or preserved left ventricular ejection fraction (LVEF)) considered for primary-prevention ICD

Main finding

As reported in the abstract

Primary prevention of SCD with ICDs in HF: incidence of SCD and alignment of ICD recommendations with risk
  • Contemporary medical management has reduced the risk of sudden cardiac death (SCD) in patients with reduced LVEF; an increasingly large proportion never requires the ICD
  • SCD is the major cause of CV mortality in HF with preserved LVEF, yet implantable cardioverter-defibrillators (ICDs) are not recommended for primary prevention in this subset
  • Recommendations for ICD use for primary prevention of SCD are no longer optimal
