123I-MIBG AND CHF• Metaiodobenzilguanidine (MIBG)
is an analogue of the false neurotransmitter guanetidine, a potent neuron blocking agent that acts selectively on sympathetic
nerves. • MIBG and noradrenaline have a
similar molecular structure and share the same uptake and storage mechanisms in the sympathetic
nerve endings. • MIBG is not metabolized by
monoamine oxidase; thus, localization of MIBG relates to the presence of sympathetic nerves and to tissue noradrenaline content.
• MIBG is currently labelled with 123-I for diagnostic purposes and
with 131-I for therapy

Sudden cardiac death: key points♥ Sudden cardiac death (SCD) is a major cause of death in the growing population of patients with heart failure♥ Ventricular arrhythmias have been documented in up to 85% of patients with severe congestive heart failure♥ Patients with severe left ventricular (LV) systolic dysfunction are among those at greatest risk for SCD♥ To date, no single test reliably predicts arrhythmic risk in patients with heart failure♥ Optimal medical treatment will improve prognosis and reduce the risk of SCD in heart failure patients♥ The implantable cardioverter-defibrillator (ICD) effectively treats malignant ventricular arrhythmias and is indicated for the secondary prevention of SCD♥ There is growing evidence for the use of the ICD for the primaryprevention of SCD
