Brief summary
This is an event-driven Phase IIIb, multicentre, randomised, clinical study to demonstrate the efficacy of AdreView™ imaging for appropriately guiding the decision of implantable cardioverter defibrillator (ICD) implantation, in New York Health Association (NYHA) class II and III heart failure participants with 25%\<=left ventricular ejection fraction (LVEF)\<=35%, and in particular, for identifying participants who are at low risk for sudden cardiac death and who would not benefit, or may suffer harm, from implantation of an ICD device.
Interventions
Iobenguane I-123 Injection, AdreView. All participants scheduled for an Iobenguane I-123 Injection, AdreView scan.
In the Iobenguane I-123 Injection group, participants with H/M ratio less or equal to 1.6 underwent ICD device implantation, while those with H/M ratio greater than or equal to 1.6 did not undergo ICD implantation.
Participants received a thyroid blocking agent before the Iobenguane I-123 Injection, AdreView, scan unless medically not indicated, according to local practice.
