Abstract

Purpose: This study aims to investigate the relationship between cardiac sympathetic nervous function (CSNF) and myocardial perfusion/function in patients with heart failure (HF) due to dilated cardiomyopathy (DCM) or ischaemic heart disease (CAD). Methods: Twenty patients (10 DCM, 10 CAD, 17 males, age 69±5 years) with NYHA class IIIb HF were studied. CSNF was evaluated by early/delayed 123I-metaiodobenzylguanidine (MIBG) uptake and regional washout (WO). Myocardial perfusion and function were evaluated by 99mTc-tetrofosmin gated single-photon emission tomography (G-SPECT) using a 20-segment model for 400 segments. In each segment, regional MIBG WO was computed as (count density in early images-count density in delayed images/count density in early images)×100. Results: DCM and CAD showed similar summed rest perfusion score (6.7±5 vs 9.5±5, p=NS) and mean ejection fraction values (29±7% vs 30±9%, p=NS). By contrast, the summed thickening score was higher in DCM than in CAD patients (26±7 vs 17±6, p
