Study on the relationship between serum level of visfatin and coronary heart disease

Abstract

Objective To study the relationship of serum visfatin level and coronary heart disease (CHD). Methods Eighty eight hospitalized patients were enrolled into the study and divided into CHD group(n = 62) and non-CHD control group(n = 26) according to the angiography results; the CHD group was further divided into single-, double-, multi-vessel affected groups. The serum level of visfatin was measured by ELISA,the lesion severity of coronary arteries was assessed by Gensini coronary scoring system, and the correlation between serum visfatin level and coronary lesion severity was evaluated statistically. Results The level of serum visfatin was significantly higher in CHD group than the control group([ 10. 77 ± 2. 63 ] μg/L vs. [ 7. 13 ± 2. 06 ]μg/L,P ＜ 0. 05). The visfatin level increased along with the the number of stenosis vessels(P ＜ 0. 05). The sermn visfatin levels of no stenosis, single-, double-, multi-vessel groups were(7. 13 ± 2. 06) μg/L,(9. 30±2. 19) μg/L,(10. 81 ± 2. 12) μg/L,(12. 79 ± 2. 20) μg/L respectively. A significant positive correlation was found between coronary lesion severity score and serum visfatin level(r = 0. 483, P ＜ 0. 01). Conclusion The visfatin may be directly related to the initiation and development of coronary diseases. The higher level of serum visfatin was, the more severe coronary artery disease would be.
