Clinical prediction model for death prior to appropriate therapy in primary prevention implantable cardioverter defibrillator patients with ischaemic heart disease: the FADES risk score

900 patients with ischaemic heart disease who received an implantable cardioverter defibrillator (ICD) for primary prevention of sudden cardiac death, 87% men, mean age 64±10 years, treated at a single tertiary care facility in The Netherlands between 1996-2009.

FADES risk score (based on NYHA ≥III, advanced age, diabetes mellitus, left ventricular ejection fraction ≤25%, and history of smoking)
