Abstract:

Objective To investigate changes and clinical significance of serum growth differentiation factor-15 (GDF-15) and hypersensitive C-reactive protein (hs-CRP) in patients with coronary slow flow (CSF). Methods A total of 132 subjects were selected and divided into the CSF group (n=66) and the control group (n=66) according to results of coronary arteriography (CAG). The serum levels of GDF-15 and hs-CRP were compared between the two groups. The correlation between serum levels of GDF-15 and hs-CRP and coronary blood flow mTFC was analyzed by Spearman correlation analysis. Binary Logistic regression was used to analyze the influencing factors of CSF. Results Compared with the control group, serum levels of GDF-15 [969.01(620.39, 1 191.01) ng/L vs. 552.73(197.06, 776.09) ng/L], hs-CRP [5.36(2.57, 6.77) mg/L vs. 0.96(0.49, 3.47) mg/L] and mTFC [27.38(23.17, 33.20) vs. 16.52(14.13, 19.12)] were significantly higher in the CSF group (P<0.05). The serum levels of GDF-15 and hs-CRP were positively correlated with mTFC in the CSF group (rs = 0.417 and 0.336, P<0.01). Binary Logistic regression analysis showed that increased GDF-15 (OR=1.004, 95%CI: 1.002-1.006, P<0.001) and hs-CRP (OR=1.604, 95%CI: 1.264-2.035, P<0.001) were independent risk factors for CSF. Conclusion The serum levels of GDF-15 and hs-CRP are elevated in CSF patients. There is a positive linear correlation between GDF-15 and hs-CRP with mTFC, which can reflect the severity of CSF.
