Figure 6 Effect of Medical Therapy and Revascularization on SPECT Perfusion Defects
Mean (±SD) and individual changes in total and ischemic left ventricular (LV) perfusion defect size (PDS) from initial SPECT to follow-up SPECT in patients randomized to medical therapy or revascularization. The dashed line represents 95% confidence interval for a real patient change. SPECT = single-photon emission computed tomography. Figure used with permission from Mahmarian et al. (90).
