Red Cell Distribution Width Can Predict the Significance of Angiographically Intermediate Coronary Lesions

Objective: In the present study, the association between red cell distribution width (RDW) with functional significance of intermediate coronary artery lesions was investigated. Materials and Methods: Two hundred and forty-six consecutive patients, 168 males and 78 females, who underwent fractional flow reserve (FFR) measurement for angiographically intermediate coronary stenosis (40-70% in quantitative coronary analysis) in the left anterior descending coronary artery were enrolled into the study. The functional significance of intermediate coronary artery lesions was determined by FFR measurement. An FFR value Results: Of the 246 patients, 62 (25.2%) exhibited significant functional stenosis (FFR Conclusion: Increased RDW levels were associated with functional significance of angiographically intermediate coronary artery stenoses.
