Results: No severe side effects of G-CSF treatment were observed. Ejection fraction determined by cardiac scan increased in the treatment group from 0.428 to 0.462 and from 0.470 to 0.496 in the control group but there was no significant improvement of left ventricular ejection fraction when the G-CSF treated group was compared to the controls (p=0.821 for cardiac scan and p=0.705 for echocardiography). Changes in Tei index was not significant in the treatment group (p=0.815) however it reached significant level in the control group (p=0.005), respectively.
