Thyroid blockingDrug
Also called Potassium Iodide, Potassium Perchlorate, Lugol's Solution
Participants received a thyroid blocking agent before the Iobenguane I-123 Injection, AdreView, scan unless medically not indicated, according to local practice.

What is being measured
The primary outcome is the main question the study is designed to answer.
All-cause Mortality
All-cause mortality included all reported deaths of participants during the study due to any cause. Percentage of participants who died due to any cause were reported.
Measured: From randomization until the end of the follow-up period (median 304 days)
Secondary outcomes (8)
Percentage of Participants With Events of Complications of Device: H/M >=1.6 in Full Analysis Set
Composite of the percentage of participants with events of hospitalization or death related to major complications of device implantation (i.e., need for thoracotomy, pericardiocentesis, or vascular surgery), complications of long-term device therapy (i.e., infection not leading to hospitalization, lead and/or generator removal/replacement, inappropriate shocks, explanation), and combined as 'complications of device' for participants with H/M >=1.6. Participants who were alive at time of database lock (DBL) were censored at the last known-alive date.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Cardiac Death
Cardiac death composed of sudden cardiac death, death due to cardiac arrhythmia, death due to heart failure, and death due to other cardiovascular causes.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Hospitalization for Cardiovascular Cause
Percentage of participants who were hospitalized for cardiovascular cause were reported.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With All-Cause Hospitalization
Percentage of participants with all-cause hospitalization were reported.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Events (Composite of the Occurrence of Resuscitated Life-Threatening Ventricular Tachycardia, Unstable Ventricular Tachyarrhythmias, Sudden Cardiac Death [SCD] and Resuscitated Cardiac Arrest)
Percentage of participants with composite events i.e occurrence of resuscitated life-threatening ventricular tachycardia, unstable ventricular tachy-arrhythmias, SCD and resuscitated cardiac arrest were reported. Participants who were alive at time of database lock (DBL) were censored at the last known-alive date.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Syncope
Percentage of participants with Syncope were reported. Participants who were alive at time of DBL were censored at the last known-alive date by date of DBL.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Implantable Cardioverter Defibrillator (ICD) Implantation
Percentage of participants with ICD implantation were reported.
Measured: From randomization until the end of the follow-up period (median 304 days)
Percentage of Participants With Events of Complications of Device
Composite of the percentage of participants with events of hospitalization or death related to major complications of device implantation (i.e., need for thoracotomy, pericardiocentesis, or vascular surgery), complications of long-term device therapy (i.e., infection not leading to hospitalization, lead and/or generator removal/replacement, inappropriate shocks, explanation), and combined as 'complications of device'.
