红细胞体积分布宽度对急性冠状动脉综合征患者心力衰竭的诊断价值

摘要

Objective To evaluate the clinical value of red cell volume distribution width(RDW) to diagnosis heart failure in acute coronary syndrome(ACS) patients. Methods We analyzed the baseline clinical data of 380 ACS patients consecutively admitted into our hospital,according to the classification of left ventricular ejection fraction(LVEF). Receiver operating characteristic (ROC) curve analysis was used to evaluate the clinical usefulness of RDW. Results There were significant differences of the age, plasma creatinine, white cell count and RDW among different LVEF groups(P<0. 01). ROC analysis results showed that the accuracy of RDW was 0. 653(P<0. 001). At the cut-off value of 13. 2% , the clinical sensitivity and specificity of RDW in ACS patients were 61. 0% and 61. 4% respectively. Conclusion As an item that can be tested rapidly and easily,RDW is useful to diagnose heart failure in ACS patients.%目的 评估红细胞体积分布宽度(RDW)对急性冠状动脉综合征(ACS)患者心力衰竭的临床应用价值.方法 连续纳入380例因ACS入院的患者,按照左室射血分数(LVEF)进行分类,分析其临床基线数据特征.利用受试者操作特征(ROC)曲线分析研究RDW对ACS患者是否存在心力衰竭的诊断价值.结果 不同LVEF的各组ACS患者,其年龄、血肌酐、白细胞和RDW均存在统计学差异(P<0.01).ROC曲线分析可知,RDW对ACS患者心力衰竭的诊断准确性可达0.653(P<0.001),以13.2%作为临界点,其诊断灵敏度为61.0%,特异度为61.4%.结论 作为一个检测便捷的指标,RDW对ACS患者出现的心力衰竭有一定的诊断价值.
