Abstract
Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. Red cell distribution width (RDW) is a measure of heterogeneity in the size of red blood cell. In this study, we aimed to investigate RDW levels in patients with CAE. The study population included 54 patients with CAE (28 males; mean age, 59 ± 12) and 40 individuals comprising the control group who had normal coronary arteries (17 males; mean age, 56 ± 10). Admission RDW was measured as part of the automated complete blood count. The RDW was significantly higher in the CAE group than the control (P < .001). Also, high-sensitive C-reactive protein (hs-CRP) levels in patients with CAE were significantly higher as compared with controls (P < .001). This study demonstrates that RDW and hs-CRP were higher in the CAE group compared with the control group. These results show that RDW is a reliable, simple, and inexpensive marker for patients with CAE.
