Effect of red cell volume distribution width on prognosis of patients with chronic severe heart failure
Objective To investigate the effect of red blood cell volume distribution width(RDW)on prognosis of patients with chronic severe heart failure.Methods A total of 101 patients with chronic severe heart failure(grade Ⅲ to Ⅳ)admitted to the Tongling People's Hospital,Anhui Province from January to December 2021 were selected and divided into elevated RDW group(40 cases)and normal RDW group(61 cases)according to the RDW level at admission.The clinical indexes of the two groups were compared.The two groups were followed up for one year after discharge,the survival and non-readmission rates of the two groups were compared,and the influencing factors were evaluated by univariate and multivariate regression analysis.Results The length of hospital stays and prevalence of diabetes in elevated RDW group were higher than those in normal RDW group,and the hemoglobin and creatinine clearance were lower than those in normal RDW group,the differences were statistically significant(P<0.05).At the end of follow-up,there was no significant difference in survival rate between the two groups(P>0.05),and the non-readmission rate in the elevated RDW group was lower than that in the normal RDW group,the difference was statistically significant(P<0.05).The results of Cox proportional risk model analysis showed that creatinine clearance,left ventricular ejection fraction,brain natriuretic peptide,and RDW were the influencing factors of re-hospitalization in patients with chronic severe heart failure(P<0.05),and creatinine clearance,left ventricular ejection fraction,and RDW were the independent influencing factors(P<0.05).Conclusion RDW is a prognostic factor of chronic and severe heart failure,and can be used as one of the important indicators in the diagnosis and treatment of heart failure in primary hospitals.
