目的:分析红细胞分布宽度(RDW)对慢性心力衰竭(CHF)患者再住院率的预测价值及对有关因素的分析。方法:收集2014年于本院确诊的CHF患者150例,以同期入院的非CHF患者150例作为对照组,将病例组患者的脑钠肽(BNP)、RDW数值进行相关性分析,按纽约心功能分级将病例组分为4组,心功能Ⅰ级组(n=41),Ⅱ级组(n=21),Ⅲ级组(n=51),Ⅳ级组(n=37),并将对照组和病例4组间的RDW数值进行组间比较,分析CHF患者至少1年内再住院率与RDW的相关性,从而分析对患者再住院率的预测价值。结果:CHF患者BNP、RDW存在明显相关性(r<0.01),对照组及各心功能分级组两两组间差异有统计学意义(P<0.05),CHF患者至少1年内再住院率与RDW有明显相关性(OR=1.684)。结论:CHF患者RDW水平与患者心衰程度、BNP数值有明确相关性;CHF患者入院时RDW数值对心衰患者再住院率有较显著的预测价值。

[Abstract]Objective:To analysis predictive value of red blood cell distribution width(RDW)about the readmission rate of chronic heart failure(CHF)patients and correlation factor analysis.Methods:A total of 150 patients with CHF in hospital were collected and divided into four groups by NYHA in 2014,classⅠ(n=41),classⅡ(n=21),classⅢ(n=51),classⅣ(n=37). Another 150 patients without CHF were selected as the control group.The correlation BNP and RDW was analyzed,the RDW differences of among CHF four groups and control group was compared,the predictive value of about the readmission rate of CHF patients among at least one years was analyzed.Results:There was significant relationship about RDW and BNP(r<0.01),the differences of among CHF four groups and control group were significant(P<0.05),the relationship of the readmission rate of CHF patients among at least one year and RDW was very obvious(OR=1.684).Conclusion:The level of RDW is obviously related with BNP and the level of heart failure in the CHF patients,also have the high predictive value about the readmission rate of CHF patients.

慢性心力衰竭(chronic heart failure,CHF)是大多数心血管疾病发展的共同终末阶段,它是以心功能不全、神经内分泌系统的激活和外周血流分布异常为特征的临床综合征,早期发现及正确诊断对CHF的治疗和判断预后有着重要意义。目前在我国CHF的诊断主要依据超声心动图和患者的主诉,而患者再住院的发生率目前并没有确切的指标可以很好的预测。脑钠肽(brain natriuretic peptide,BNP)在心力衰竭(HF)诊断及预后评价中的重要性已得到证实[1-2]。……
