The relationship between red cell distribution width with clinical characteristics: analysis based on 16681 chronic systolic heart failure patients with different causation

Objective To determinate the prognostic value of red cell distribution (RDW) and the relationships between RDW and clinical characteristics in patients with CHF caused by different aetiologies. Material and methods 16681 in-hospital patients from 12 hospital of Hubei province, China, with diagnosis of chronic systolic HF and LVEFMCV>82FL) groups in patients with RDW>16%; death and survival groups according to the result of follow-up. Compared with RDW14.8% were 0.892 (95% CI 0.818 to 0.973, p=0.01), 0.859 (95% CI 0.793 to 0.931, p
