Abstract
Aim and objectives: to assess the association between Visfatin level-as an independent marker -and the presence of coronary artery ectasia in patients undergoing diagnostic coronary angiography.
Patients and Methods: A total of 90 participants were recruited from candidates undergoing diagnostic coronary angiography in the Cath lab of Cardiology Department at Ain Shams University. They were then divided into three groups. The first group included individuals with normal coronaries, the second patients with coronary artery disease (CAD) without ectasia, and the third is patients with isolated coronary artery ectasia (CAE). After history taking, they all underwent biochemical tests for serum Visfatin, HBA1C%, serum creatinine and CRP. Univariate and correlation analysis was done.
Results: regarding demographic and clinical characteristics of our study population, we found that only higher age and being a smoker was significantly associated with the presence of ectasia. High level of serum Visfatin was strongly significantly associated with the presence of ectasia. Serum creatinine and CRP displayed a similar pattern. Moreover, we found that the mean level of serum Visfatin increases with the severity of ectasia according to Markis classification. Finally, Roc showed that a cut-off value of >34 ng/ml demonstrated a sensitivity of 89% and a specificity of 87% of predicting CAE.
Conclusion: high serum Visfatin level is significantly associated with the presence of coronary artery ectasia. Also, it is positively correlated with its severity according to Markis classification. Hence, it can be a valuable predictor of CAE
