Figure 6: Graphs of changes in LV ejection fraction. Top: Control animals (n = 6). Bottom: AAV-VEGFtreated animals (n = 6). Control animals had progressive deterioration in ejection fraction 8 weeks after infarction. AAV-VEGF prevented decline in ejection fraction in treated animals subjected to same intervention. ** = P less than .01 compared with that at 3 days after infarction (paired t test),
= P less than .01 compared with that of control animals (unpaired t test).
