The Effect of Granulocyte Colony Stimulating Factor (G-CSF) on Myocardial Function After Acute Anterior Myocardial Infarction, a Prospective Double Blind Randomized Placebo Controlled Study
- Conditions
- Myocardial Infarction
- Interventions
- Drug: placebo infusion of normal saline
- Registration Number
- NCT00756756
- Lead Sponsor
- Shiraz University of Medical Sciences
- Brief Summary
The investigators applied G-CSF to patients 2 weeks after acute anterior MI and successful PCI to evaluate the efficacy and safety of G-CSF in improving myocardial function as cytokine which improve inflammation and mobilize stem cells from bone marrow for regeneration of myocardium.
- Detailed Description
Ten patients in the treatment group and 10 patients in the control group were enrolled in this prospective, randomized, double blinded study. Two weeks after myocardial infarction that was accompanied by successful recanalization and stent implantation, the patients of the treatment group received 10 μg/kg body weight per day (divided BID) G-CSF subcutaneously for treatment duration of maximum 5.0 days. In both groups, ejection fraction was evaluated with echocardiography and cardiac scan (Gated SPECT method) 10 days after myocardial infarction and after 6 months. Tei index was measured by echocardiography.
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.
