Objective:To analyze correlations among levels of red cell volume distribution width(RDW),hematocrit(HCT),neutrophil/lymphocyte ratio(NLR)and severity of acute heart failure.Methods:A total of 128 patients with acute heart failure admitted to this hospital from August 2021 to March 2023 were selected as the study group,and 128 healthy subjects in this hospital during the same period were selected as the control group.The levels of RDW,HCT and NLR were compared between the two groups and the patients with acute heart failure of different New York Heart Association cardiac function grades.Spearman correlation analysis was used to analyze the correlations among the RDW,HCT,NLR levels and the severity of acute heart failure.Results:The levels of RDW and NLR in the study group were higher than those in the control group,and the level of HCT was lower than that in the control group,the differences were statistically significant(P<0.05).The levels of RDW and NLR in the patients with grade Ⅳ acute heart failure were higher than those in the patients with grade Ⅲ and gradeⅡ,and those in the patients with gradeⅢ were higher than those in the patients with gradeⅡ;the HCT levels in the patients with grade Ⅳacute heart failure were lower than those in the patients with grade Ⅲ and grade Ⅱ,and that in the patients with grade Ⅲ was lower than that in the patients with gradeⅡ;and the differences were statistically significant(P<0.05).Spearman correlation analysis showed that the RDW and NLR levels were positively correlated with the severity of acute heart failure(r>0,P<0.05),while the HCT level was negatively correlated with the severity of acute heart failure(r<0,P<0.05).Conclusions:The RDW and NLR levels are positively correlated with the severity of acute heart failure,while the HCT level is negatively correlated with the severity of acute heart failure.
