Insights
Reduced circulating endothelial progenitor cells (EPCs) are a significant risk factor for coronary slow flow (CSF) disease. This finding highlights EPCs as a potential biomarker for CSF.
Area of Science:
- Cardiovascular Medicine
- Cell Biology
- Vascular Biology
Context:
- Coronary slow flow (CSF) is a condition affecting coronary angiography.
- The role of endothelial progenitor cells (EPCs) in CSF pathogenesis is not fully understood.
Purpose:
- To investigate whether a reduced number of circulating EPCs is an independent risk factor for patients diagnosed with CSF.
Summary:
- The study compared 30 CSF patients with 30 controls, finding significantly lower EPC counts in the CSF group (35.7 ± 5.9 vs. 53.2 ± 5.9).
- Circulating EPC levels showed a correlation with TIMI frame counts, a measure of coronary flow, but were not associated with traditional risk factors like smoking or diabetes.
- These results indicate that decreased circulating EPCs are an independent risk factor for CSF.
Impact:
- Identifies a novel, independent risk factor for coronary slow flow.
- Suggests that circulating EPC counts could serve as a potential diagnostic biomarker for CSF.
- Opens avenues for future research into therapeutic strategies targeting EPCs for CSF management.
Objective:
To explore if reduced number of circulating endothelial progenitor cells (EPCs) is a risk factor for patients with coronary slow flow (CSF).
Methods:
Thirty patients with CSF and 30 age and gender matched control subjects with normal coronary angiography were included in the study. Mononuclear cells were isolated from peripheral blood by Ficoll density gradient centrifugation and plated on fibronectin-coated culture dishes. EPCs were characterized as adherent cells double positive for DiI-AcLDL-uptake and lectin-binding by converted fluorescence microscope (×200).
Results:
Smoking, diabetes mellitus, hypertension and the levels of plasma lipoprotein profile were similar between the two groups (all P > 0.05). The number of EPCs was significantly lower in patients with CSF compared with control subjects (35.7 ± 5.9 vs.53.2 ± 5.9, P < 0.01). TIMI frame counts was correlated with circulating EPCs number (OR = 0.424, 95%CI 0.358 - 0.621, P < 0.01) and not associated with gender, age, smoking, diabetes mellitus, hypertension and the levels of plasma lipoprotein profile.
Conclusion:
Decreased circulating EPCs is an independent risk factor for CSF.
