Abstract
Background
Increased levels of visfatin, a novel adipocytokine, are reported in atherosclerosis, obesity, and type 2 diabetes. The aim of the present study was to investigate the relationship between coronary slow flow (CSF) and visfatin in patients undergoing elective coronary angiography for suspected coronary artery disease.
Patients and methods
A total of 140 recruited participants (90 patients with CSF and 50 controls) were divided into two groups according to their coronary flow rates. Coronary flow was quantified by thrombolysis in myocardial infarction (TIMI) frame count (TFC).
Results
Serum visfatin levels were higher in the CSF group than in the control group (3.29 ± 1.11 vs. 2.70 ± 1.08 ng/ml, p = 0.003). A significant correlation was found between TFC and visfatin (r = 0.535, p < 0.001). The area under the receiver operating characteristic curve was 0.720 (95 % confidence interval, 0.622–0.817, p < 0.001) for visfatin in the diagnosis of CSF. If a cut-off value of 2.59 ng/ml was used, higher levels of visfatin could predict the presence of CSF with 78.9 % sensitivity and 64.0 % specificity.
Conclusion
Visfatin levels might be a useful biomarker for predicting CSF in patients undergoing diagnostic coronary angiography.
