Primary Outcome Measures
NameTimeMethod
Relationship Between the Occurrence of Adverse Cardiac Event and 123I-mIBG Uptake on Planar Scintigraphy Categorized as High or Low Heart to Mediastinum (H/M) RatioApproximately 24 months from the date of administration of 123I-mIBG

H/M ratio for 123I-mIBG uptake at 3 hours 50 minutes post administration was calculated by dividing the counts/pixel in the total myocardium region of interest (ROI) by the counts/pixel in the 7x7 pixel mediastinal ROI. Assessments were done by 3 independent readers. H/M ratios were categorized as 'Low' and 'High' based on being \<1.6 or ≥1.6 respectively. The efficacy of 123I-mIBG was based on the prognostic value of the imaging data collected relative to time to adverse cardiac events.
