Insights
Granulocyte colony-stimulating factor (G-CSF) treatment improved cardiac function and reduced ventricular remodeling in heart failure patients post-myocardial infarction by increasing endothelial progenitor cells (EPCs). This therapy offers a promising approach for heart failure management.
Area of Science:
- Cardiology
- Regenerative Medicine
Context:
- Heart failure following myocardial infarction (MI) presents a significant clinical challenge.
- Conventional treatments have limitations in fully restoring cardiac function and preventing adverse ventricular remodeling.
Purpose:
- To investigate the efficacy of granulocyte colony-stimulating factor (G-CSF) in improving cardiac function in patients with heart failure post-MI.
- To assess the impact of G-CSF on endothelial progenitor cell (EPC) mobilization and cardiac remodeling markers.
Summary:
- A randomized controlled trial involving 38 patients with heart failure post-MI compared G-CSF treatment with a control group receiving conventional therapy.
- G-CSF treatment significantly increased peripheral blood EPCs and improved cardiac function, including left ventricular ejection fraction (LVEF), compared to the control group.
- Both groups showed a reduction in brain-type natriuretic peptide (BNP) levels, indicating improved cardiac status.
Impact:
- G-CSF therapy demonstrates potential in enhancing cardiac repair mechanisms post-MI.
- Mobilization of EPCs by G-CSF may be a key factor in improving cardiac function and mitigating ventricular remodeling.
- These findings suggest G-CSF as a potential therapeutic agent for heart failure management after myocardial infarction.
Objective:
To study the changes of cardiac function following treatment with granulocyte colony stimulating factor (G-CSF) in patients with heart failure after myocardial infarction.
Methods:
Thirty-eight patients with heart failure after myocardial infarction were randomized into G-CSF treatment group and control group. All the patients received conventional treatment (medication and interventional therapy), and the patients in treatment group were given additional G-CSF (600 µg/day) for 7 consecutive days. The plasma level of brain-type natriuretic peptide (BNP) and the number of endothelial progenitor cells (EPCs) in the peripheral blood were detected before and at 7 days and 4 months after the treatment. The cardiac functions (LVSD, EDV, and LVEF) were evaluated by ultrasonic imaging before and at 2 weeks and 4 months after the treatment.
Results:
The number of EPCs was significantly higher in the treatment group than in the control group after the treatment especially at 7 days (P<0.01). In both groups, BNP level was lowered significantly after the treatment to recover the normal level (P<0.01). The cardiac functions were improved in all the patients at 7 days and 4 months after the treatment, and the improvement was more obvious in the treatment group (P<0.05), especially in terms of LVEF at 4 months after the treatment (P<0.01).
Conclusion:
EPC mobilization by G-CSF can effectively improve the cardiac functions and lessen ventricular remodeling in patients with heart failure after myocardial infarction.
