Evaluation of the relationship between the RDW/albumin ratio and coronary artery ectasia

Aims: Coronary artery ectasia (CAE) is a vascular abnormality associated with inflammation and adverse cardiovascular outcomes. The red blood cell distribution width-to-albumin ratio (RAR) has emerged as a novel biomarker reflecting systemic inflammation and nutritional status. This study aimed to evaluate the relationship between RAR and the presence of CAE. Methods: In this retrospective study, 80 patients diagnosed with CAE via coronary angiography and 80 age-and sex-matched healthy controls were included. Laboratory parameters, including RDW, serum albumin, and RAR, were analyzed. The Mann-Whitney U test was used for group comparisons, and significance was set at p0.05). Median (IQR) serum albumin levels were significantly lower in the CAE group compared to controls [41.0 (39.0–43.9) g/L vs. 43.9 (42.0–45.7) g/L; p
