Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Assessment of myocardial sympathetic innervation (as either normal or abnormal) for identifying risk of adverse cardiac event. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Assessment of myocardial sympathetic innervation (numerical H/M ratio) for identifying risk of adverse cardiac event. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Quantitative myocardial 123I-mIBG uptake to identify HF subjects at higher risk of earlier HF progression, potentially fatal ventricular arrhythmias, or cardiac death. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Modeling to predict risk for adverse cardiac events. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Safety profile [ Time Frame: 24 hours post dose ] [ Designated as safety issue: Yes ]

Criteria

Inclusion Criteria:
