title: [Relationship between red cell volume distribution width and cardiac function in acute coronary syndrome patients].
abstract: OBJECTIVE
  To evaluate the relationship between red cell volume distribution width (RDW) and cardiac function in acute coronary syndrome (ACS) patients.
  
  
  METHODS
  We analyzed the baseline clinical data of 228 ACS patients consecutively admitted into our hospital according to the classification of RDW and NYHA function class. Correlation analysis was made respectively between RDW and plasma creatinine and left ventricular ejection fraction (LVEF).
  
  
  RESULTS
  There were significant differences of age [Group Q(1) to Group Q(4): (60 ± 12), (65 ± 11), (64 ± 11), (71 ± 12) years old], plasma creatinine [Group Q(1) to Group Q(4): (70 ± 19), (76 ± 24), (74 ± 20), (85 ± 26) µmol/L] and LVEF [Group Q(1) to Group Q(4): (57 ± 9)%, (55 ± 10)%, (53 ± 11)%, (49 ± 11)%] among different RDW groups (P = 0.0000, 0.0054, 0.0002, respectively). Comparing to NYHA function I, patients of NYHA function IV had a higher RDW (13.9% ± 1.2% vs 13.1% ± 5.7%, P < 0.05). There were significant negative correlations between RDW and LVEF (r = -0.30, P < 0.01).
  
  
  CONCLUSIONS
  RDW may be significantly related to cardiac function in Chinese ACS patients.
