123I-MIBG SPECT for Evaluation of Patients with Heart Failure.
Heart failure (HF) is characterized by activation of the sympathetic cardiac nerves. The condition of cardiac sympathetic nerves can be evaluated by (123)I-metaiodobenzylguanidine ((123)I-MIBG) imaging. Most cardiac (123)I-MIBG studies have relied on measurements from anterior planar images of the chest. However, it has become progressively more common to include SPECT imaging in clinical and r...
متن کاملRenal Function in Relation to Cardiac 123I-MIBG Scintigraphy in Patients with Chronic Heart Failure
The aim of this study was to explore if estimates of renal function could explain variability of (123)I-metaiodobenzylguanidine ((123)I-MIBG) assessed myocardial sympathetic activity. Furthermore estimates of renal function were compared to (123)I-MIBG as predictors of cardiac death in chronic heart failure (CHF). Semi-quantitative parameters of (123)I-MIBG myocardial uptake and washout were ca...
متن کاملRisk stratification in chronic heart failure.
Despite advances in medical and surgical management, the prognosis of chronic heart failure remains poor. Few patients with chronic heart failure can be considered to have a good prognosis, but different trials have indicated a 6 month mortality between 5% and 60% depending on the severity of heart failure; identifying patients at truly low risk is difficult. A host of factors have been identif...
متن کاملRelationship between plasma norepinephrine at peak exercise and 123I-MIBG imaging of the heart and lower limbs in heart failure.
BACKGROUND Past studies suggested that plasma norepinephrine during exercise originates in sympathetic nerve endings and that the main origin differs among pathophysiological conditions. AIMS This study investigated the most important site of sympathetic terminals as an origin of plasma norepinephrine during exercise in patients with heart failure using (123)I- metaiodobenzylguanidine (MIBG) ...
متن کاملAcute heart failure risk stratification: can we define low risk?
The emergency department evaluation and management of patients who have potential acute heart failure syndromes (AHFS) has remained a significant challenge for decades. The emergency physician's diagnostic tools for heart failure have remained limited, and the complexity of the syndrome itself has led to risk-averse practice styles with extremely high admission rates. Recently, new diagnostic m...
