Clinical significance of erythrocyte distribution width serum total bilirubin and free triiodothyronine in patients with chronic heart failure
Objective To analyze the relationship between serum red blood cell distribution width(RDW),total bilirubin(TBIL),and free triiodothyronine(FT3)levels,and to explore the clinical significance of the three indexes in congestive heart failure(CHF).Methods A total of 160 patients with chronic heart failure(heart failure group)who met the criteria and 141 patients with non-heart failure without severe liver and kidney insufficiency(control group)who were admitted to Anshan Central Hospital from October 2021 to October 2022 were selected as the study subjects.The patients in the heart failure group were divided into grade Ⅱ(55 cases),grade Ⅲ(51 cases)and grade Ⅳ(54 cases)according to the New York Heart Association(NYHA)cardiac function classification,and the differences of the above indexes between the heart failure group and the control group were statistically analyzed,and the correlation between the above indicators and the cardiac function grade of CHF patients was studied,and the combined diagnostic value of RDW,TBIL and FT3 in CHF patients was discussed.Results RDW-CV and TBIL were positively correlated with cardiac function grade,and FT3 was negatively correlated with cardiac function grade,and the area under the curve(AUC)of the combined prediction probability of the three was greater than that of a single factor.Conclusion RDW-CV,TBIL and FT3 are predictors of CHF,RDW-CV and TBIL are positively correlated with cardiac function grade,and FT3 is negatively correlated with cardiac function grade.
