Text: The percentage of left ventricle perfusion abnormalities outside 2. 5 SDs of those of normal persons (based on 20 disease-free individuals) on the dipyridamole PET image of normalized counts worsened in controls (mean + / - SE, + 10. 3 % + / - 5. 6 %) and improved in the experimental group (mean + / - SE, -5. 1 % + / - 4. 8 %) (P =. 02) ; the percentage of left ventricle with activity less than 60 % of the maximum activity on the dipyridamole PET image of normalized counts worsened in controls (+13. 5 % + / - 3. 8 %) and improved in the experimental group (-4. 2 % + / - 3. 8 %) (P =. 002) ; and the myocardial quadrant on the PET image with the lowest average activity expressed as a percentage of maximum activity worsened in controls (-8. 8 % + / - 2. 3 %) and improved in the experimental group (+4. 9 % + / - 3. 3 %) (P =. 001).
