Figure 3 Serial SPECT images and polar plot of a patient randomized to medical therapy. Baseline SPECT (A) shows a large perfusion defect (arrows) in the short (SA), horizontal long (HLA), and vertical long (VLA) axis slices after stress (upper panels) which improves with rest imaging (lower panels). Ischemia is present in the right and circumflex vascular territories. Total LV PDS is 30% with 25% ischemia (green) and 5% scar (black). The patient was treated with a beta-blocker, calcium-channel blocker, and statin. Repeat SPECT (B) is entirely normal. This patient had no subsequent cardiac event. Other abbreviations as in Figure 1.
