Visfatin as marker of isolated coronary artery ectasia and its severity

Abstract

Several studies have demonstrated the relationship between visfatin and increased risk of diseases caused by inflammation, however, the relationship between visfatin and coronary artery ectasia (CAE) is still unknown. The aim of our study is to investigate the association between serum visfatin with presence of coronary ectasia and its severity. We enrolled 85 individuals including 35 CAE patients (mean age: 58.40 ± 9.82 years) and 50 control persons (mean age: 53.24 ± 8.81 years). These participants underwent some biochemical tests including visfatin, fasting blood glucose and lipid profiles. In univariate analysis, the serum level of visfatin was significantly associated with ectasia in all patients with CAE and CAD coexisting with CAE groups, but a trend toward significance in isolated CAE group. In multivariate analysis, visfatin showed independently significant association with presence of ectasia in all patients with ectasia and in CAD coexisting with ectasia groups, but not significant in isolated CAE group. Visfatin was also independently associated with severity of ectasia according to MARKIS classification. We conclude that visfatin independently can be the useful predictor for the presence and severity of coronary ectasia.
