Myocardial glucose uptake after dobutamine stress in chronic hibernating swine myocardium

Background In patients with hibernating myocardium, regional uptake of the glucose analog 2-fluorine 18-fluoro-2-deoxy-D-glucose (FDG) is increased under resting conditions. It is unclear whether the degree of increased FDG uptake correlates with the degree of impaired blood flow response and whether chronic changes in the glucose transporters may play a role in the enhanced FDG uptake under fasted conditions.
