Red cell distribution width should be assessed together with other inflammatory markers in daily clinical practice

摘要

We have read the article 'Elevated red blood cell distribution width is associated with higher recourse to coronary artery bypass graft' written by Ephrem and Kanei [1] with great interest. The authors have demonstrated an independent association of elevated red cell distribution width (RDW) with recourse to coronary artery bypass grafting. The study is successful in design and documentation. We believe that these findings will guide further studies about RDW as a surrogate marker of endothelial dysfunction and inflammation in patients with coronary artery disease. We want to thank the authors for their contribution.
