Background: Coronary collateral circulation (CCC) plays a vital role in the myocardial blood supply, especially forischemic myocardium. Evidence suggests that the visfatin and 25-hydroxyvitamin D3 [25(OH)D3] levels are related to the degree and incidence of vascular stenosis associated with coronary artery disease; however, few studies have evaluated the effect of visfatin and 25(OH)D3 on CCC development in patients with chronic total occlusion (CTO).This study aimed to evaluate the relationship between the serum visfatin and 25(OH)D3 levels and CCC in patients with CTO.Methods: A total of 189 patients with CTO confirmed by coronary angiography were included. CCC was graded from 0 to 3 according to the Rentrop-Cohen classification. Patients with grade 0 or grade 1 collateral development were included in the poor CCC group (n = 82), whereas patients with grade 2 or grade 3 collateral development were included in the good CCC group (n = 107). The serum visfatin and 25(OH)D3 levels were measured by ELISA.Results: The visfatin level was significantly higher in the poor CCC group than in the good CCC group, and the 25(OH)D3 level was significantly lower in the poor CCC group than in the good CCC group (P = 0.000). Correlation analysis showed that the Rentrop grade was negatively correlated with the visfatin level (r = − 0.692, P = 0.000) but positively correlated with the 25(OH)D3 level (r = 0.635, P = 0.000). Logistic regression analysis showed that the visfatin and 25(OH)D3 levels were independent risk factors for CCC (odds ratio 1.597, 95% confidence interval 1.300–1.961, P = 0.000 and odds ratio 0.566, 95% confidence interval 0.444–0.722, P = 0.000, respectively). The visfatin and25(OH)D3 levels can effectively predict the CCC status.Conclusion: Serum visfatin and 25(OH)D3 levels are related to CCC development and are independent predictors of poor CCC.
