Association of C-Reactive Protein to Albumin Ratio in Patients with Isolated Coronary Artery Ectasia

Abstract Background Coronary artery ectasia (CAE) is defined as diffuse or localized dilatation of coronary artery lumen with a diameter of 1.5 to 2.0 times the adjacent normal coronary artery. The C-reactive protein to albumin ratio (CAR) is a useful inflammatory marker, which has been documented in coronary artery disease. Objective To analyze the association of CAE and CAR. Methods A case-control protocol was used in this study. We included 102 consecutive patients with isolated CAE without stenosis (56 men and 46 women; mean age 60.4 ± 8.8 years). The control subjects consisted of an equal number of sex and age matched patients with normal coronary arteries (55 men and 47 women; mean age 61.2 ± 9.1 years). Clinical features, laboratory findings, and medication use history were recorded. Student’s t test, Mann-Whitney U test, chi-square test, and linear and logistic regression analysis were performed.
