    ObjectiveThis study was undertaken to determine the relationship between the red cell distribution width (RDW) and the one year outcomes in Chinese patients with stable angina pectoris.MethodsA total of 1,442 patients with stable angina pectoris on admission were divided into four groups according to quartiles of the baseline RDW. The relationships between the RDW and one-year cardiac mortality as well as the incidence of acute coronary syndrome (ACS) were assessed.ResultsHigher RDW values were associated with an increased one-year cardiac mortality (quartile 1: 0.51%; quartile 2: 0.56%; quartile 3: 0.86%; quartile 4: 2.27%; p<0.001) and one-year ACS (quartile 1: 1.55%; quartile 2: 1.96%; quartile 3: 2.89%; quartile 4: 3.70%; p<0.001). A logistic regression analysis revealed that the RDW independently predicted cardiac mortality (OR: 1.544, 95% CI: 1.058-3.216, p<0.001) and ACS (OR: 1.861, 95% CI: 1.226-3.487, p<0.001) during a one-year follow-up in patients with stable angina pectoris.ConclusionThe present study indicates that an elevated RDW value is associated with an increased risk of one-year adverse outcomes in patients with stable angina pectoris.
