Figure 3 Change in LV Function Over Time

Global and regional left ventricular (LV) function were measured using echocardiography immediately before and 3 weeks after intramyocardial injection with either phVEGF₁₂₅ (yellow bars) or saline (orange bars). Mean value for left ventricular ejection fraction (LVEF) increased slightly but with a large standard deviation (error bar) while mean value for LVEF fell in the saline-treated animals but also with a large standard deviation. Wall thickening (WT) in the ameroid territory increased slightly in the vascular endothelial growth factor (VEGF)-treated animals and fell in the saline-treated animals.
