Figure 7 The time course of changes in left ventricular ejection fraction (LVEF) (A), left ventricular end-diastolic dimension (LVEDD) (B), and left ventricular end-diastolic pressure (LVEDP) (C) in different experimental groups. Statistically significant (p < 0.05) group-by-time interactions (analysis of variance for repeated measurements) are indicated by the following: # = all groups; $ = control x EPO(0) group; & = control x EPO(6h) group;  = EPO(0) x EPO(6h) group. (D) Infarct size at 4 weeks after myocardial infarction in different experimental groups. Open circles = infarct size in each animal. *p < 0.05 versus the control group. EPO = erythropoietin.
