文摘

Circulating endothelial progenitor cells (EPCs), which have the ability to differentiate into mature endothelial cells, can elicit angiogenesis, vasculogenesis and vessel repair in cardiac ischemia and vascular injuries caused by endothelial damage. Serum 1,5-anhydro-d-glucitol (1,5-AG), which is a useful clinical marker of postprandial hyperglycemia, eicosapentaenoic acid (EPA), and arachidonic acid (AA) are newly identified risk factors for coronary artery disease (CAD). However, no previous study has reported the associations between EPCs and 1,5-AG, EPA, and AA levels in CAD patients with type 2 diabetes mellitus (DM).

Methods

Peripheral EPCs, assessed as CD34 + cells co-expressing CD133 and vascular endothelial growth factor receptor-2, were studied in 76 CAD patients (mean age, 69.2 ± 11.3 years) with DM. Serum 1,5-AG, EPA, and AA levels were measured.

Results

EPC numbers showed a significant association with 1,5-AG and HbA1c (r = 0.290; p = 0.037 and r = − 0.328; p = 0.011, respectively). In addition, there were significant associations between EPC numbers and EPA and body mass index (BMI) (r = 0.354; p = 0.027 and r = − 0.402; p = 0.002, respectively). In multiple linear regression analysis, HbA1c, BMI, and EPA values had significant associations with EPC numbers (β = − 0.316, 95% confidence interval (CI) -0.256 to − 0.008, p = 0.037; β = − 0.413, 95% CI − 0.099 to − 0.017, p = 0.007; and β = 0.400, 95% CI 0.004 to 0.002, p = 0.010, respectively).

Conclusions

EPC number is associated with HbA1c, 1,5-AG, EPA, and BMI values, suggesting that postprandial hyperglycemia and n-3 polyunsaturated fatty acids contribute to EPC recruitment in CAD patients with type 2 DM.
