Aim: The aim of this study is to examine uric asid (UA) and high sensitive C-Reactive protein (Hs-CRP) levels in patients with coronary artery ectasia (CAE). Materials and Methods: Ninety-eight patients with isolated CAE (mean age 57.5 +/- 10.3), (group-I), 110 patients with CAD but without CAE (mean age 56.3 +/- 10.7), (group-II), and 105 patients with normal coronary angiographies (mean age 58.1 +/- 10.8), (group-III) were included in the study. Blood samples of all individual were taken after coronary angiography from an antecubital vein, the patients uric acid and Hs-CRP levels were assessed. The severity of ectasia was evaluated and categorized according to Markis. Results: A significant difference was not seen in serum uric acid and Hs-CRP levels between CAE and CAD groups. However, relative to the control group, uric acid and Hs-CRP levels in CAE and CAD groups were higher to a significant degree (p=0.001, p<0.001, respectively), (p<0.001, p<0.001, respectively). The statistical significant was detected between subgroups type I and type IV, Hs-CRP and UA were statistically high in subgroup type I. (p=0.012, p=0.033, respectively) In multiple regression analysis, CAE and CAD were independently associated with UA (beta=0.76; p<0.001, beta=0.68; p<0.001, respectively) and Hs-CRP (beta=0.66; p<0.01, beta=0.62; p<0.01, respectively) along with diabetes mellitus (beta=0.61; p=0.039, beta=0.94; p=0.028, respectively). Conclusion: In conclusion, the blood uric acid and Hs-CRP values in our study have been observed to be higher in the individuals with coronary arteri ectasia in comparison to normal individuals, and the increase in these values were found to be parallel to the extent of the ectasia.
