  Purpose

In the past two years, subjects participated in a medical research study using the investigational drug called 123I-Iodine meta-iodobenzylguanidine (123I-mIBG)(pronounced "123 I oo dine-meta ioo doo ben zul gwan nid deen"). The sponsor of that study (GE Healthcare) is now interested in gathering data concerning heart failure subjects and cardiac events, since they were enrolled in the original study. There will be no injections of radioactive imaging agents or repeat imaging studies.

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Demonstrate the prognostic usefulness of assessment of myocardial sympathetic innervation, measured by the numerical H/M ratio on planar 123I-mIBG imaging, for identifying heart failure subjects at higher risk of experiencing an adverse cardiac [ Time Frame: 24 months after dosing date in MBG 311/312/312C ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To identify the optimum H/M threshold that provides the best combination of Sensitivity and Specificity for identifying HF subjects at higher risk of experiencing an ACE during 24 months of follow-up. To demonstrate the prognostic usefulness of the heart [ Time Frame: 24 months after dosing date in MBG 311/312/312C ] [ Designated as safety issue: No ]

Study Population

Heart Failure Subjects who participated in MBG 311/312/312C.

Criteria

Inclusion Criteria:

  • The subject was a Heart Failure subject who signed informed consent for MBG311, MBG312, or MBG312C.
  • The subject was administered 123I-mIBG in MBG311, MBG312, or MBG312C.
  • The subject completed the late planar imaging assessments (at a minimum) required by the protocols for MBG311, MBG312, or MBG312C.
  • The subject agrees to allow the investigator access to medical records, including those relating to subject death should this occur.

Exclusion Criteria:

  • The subject withdrew or was withdrawn from MBG311, MBG312, or MBG312C.
  • The subject was considered lost-to-follow-up (6 months without contact) in MBG311, MBG312, or MBG312C.
