OBJECTIVES The purpose of this study was to investigate the relationship between hepatic triglyceride content and both myocardial function and metabolism in type 2 diabetes mellitus (T2DM). BACKGROUND Heart disease is the leading cause of mortality in T2DM. Central obesity and hepatic steatosis, both hallmark abnormalities in T2DM, have been related to increased risk of heart disease. METHO...

A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...

Right heart failure (RHF) is characterized by chamber-specific reductions of myocardial norepinephrine (NE) reuptake, beta-receptor density, and profiles of cardiac sympathetic nerve ending neurotransmitters. To study the functional linkage between NE uptake and the pre- and postsynaptic changes, we administered desipramine (225 mg/day), a NE uptake inhibitor, to dogs with RHF produced by tricu...

A discrete MIBI avid lung lesion was found in cinematic views of myocardial perfusion imaging (MPI) of a 59 year-old woman. Interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. MPI was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  She had no...

Introduction: Left ventricular ejection fraction (LVEF) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting (CABG). This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gated signle photon emission compu...

UNLABELLED Catecholamine regulates myocardial glucose use. However, the effect of inhaled anesthetics on myocardial glucose transport stimulated by catecholamine is unclear. We studied the effect of halothane and sevoflurane on uptake of 2-deoxyglucose stimulated by norepinephrine in neonatal cardiomyocytes and the mechanism that modulates glucose transport. We studied the effects of halothane ...

BACKGROUND To investigate whether an apoptotic process demonstrated by (99m)Tc-annexin-V ((99m)Tc-AV) uptake correlates with left ventricular remodeling (LVR) after myocardial infarction, we assessed (99m)Tc-AV uptake in rat model of myocardial ischemia and reperfusion. METHODS The left coronary artery (LCA) of 15 rats was occluded for 20 to 30 min, followed by reperfusion. After 2 weeks, (99...

Aims To investigate whether degree of nonalcoholic fatty liver disease (NAFLD) is associated with myocardial dysfunction related to impaired glucose uptake in patients type 2 diabetes. Materials and methods In total, 131 diabetes from a tertiary care hospital were included this study. Myocardial was assessed using [18F]-fluorodeoxyglucose-positron emission tomography. Hepatic steatosis fibrosis...
