Fig. 6.

Upper panels show three representative images from patients presenting with chest pain syndromes. The left top panel is from a patient with an acute coronary syndrome (ACS). The arrow points to the stent placed at the site of the culprit lesion. Substantial FDG uptake is seen at that site. The middle top panel is from a patient with a stable coronary syndrome. A stent placed at the culprit lesion is seen. The FDG uptake associated with that lesion is modest. The right top panel shows a remotely stented lesion for comparison. The bottom panels demonstrate group values for FDG uptake. Patients with ACS had higher FDG uptake in association with culprit lesions. The fact that FDG uptake was not higher after stent placement for ACS compared to stent placement for stable syndromes suggests that the increased FDG uptake is not the result of stenting alone, but rather is due to the coronary syndrome.
