Relationship Between Red Cell Distribution Width and Stroke in Patients With Stable Chronic Heart Failure: A Propensity Score Matching Analysis
2015
Aim:We aimed to investigate the association between baseline red cell distribution width (RDW) level and the risk of stroke in patients with heart failure (HF).Methods:A total of 153 consecutive patients with HF (New York Heart Association [NYHA] I-III and left ventricular ejection fraction of <40%) were included in this prospective study. All the patients were followed up for 1 year, and during this period the cerebrovascular disease was questioned.Results:In matched population, using propensity score matching comparing patients with HF having stroke with patients without stroke, we found significantly increased basal RDW and serum uric acid. The receiver-operating characteristic curves of RDW for predicting stroke are performed. An RDW ≥15.2% measured on admission had 87% sensitivity and 74% specificity in predicting stroke in patients with HF (area under the curve: 0.923, 95% confidence interval: 0.852-0.994, P < .001).Conclusion:In conclusion, this study demonstrated that RDW may be important hematolo...
