Objective:To observe the clinical efficacy of angiotensin-receptor neprilysin inhibitors (ARNI) in the treatment of maintenance hemodialysis (MHD) with heart failure.Methods:The clinical data of heart failure patients who accepted MHD in Central China Fuwai Hospital were retrospectively collected. All patients accepted regular treatments of heart failure, and then the treatment group was treated with ARNI, while the control group was treated with valsartan. The treatment course was 6 months. The cardiac parameters: left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD), pulmonary artery pressure, right ventricular end-diastolic dimension (RVED), right atrial end-diastolic dimension (RAED), N-terminal pro-B-type natriuretic peptide (NT-pro BNP), and serum potassium were collected and compared between the two groups. Multivariate ordered logistic regression analysis was adopted to analyze the influencing factors of treatment effect.Results:A total of 60 MHD patients with heart failure were enrolled with age of (53.92±11.88) years old, 37 males (61.7%), dialysis age of (27.83±12.92) months, and blood pressure of (154.22±15.27) mmHg/(85.43±12.31) mmHg. (1) There was no significant difference of the clinical data and cardiac parameters between the treatment group ( n=30) and the control group ( n=30) before treatment (all P>0.05); (2) After treatment of 6 months, the total effective rate [28/30(93.3%)] in the treatment group was significantly higher than that in the control group [20/30(66.7%)] and the rehospitalization rate [2/30(6.7%)] in the treatment group was significantly lower than that in the control group [10/30(33.3%)] (both P<0.05); (3) After treatment of 6 months, LVEF, LVEDD, LVESD, pulmonary artery pressure, RVED, RAED, NT-pro BNP, and blood pressure were all improved significantly compared with the baseline in both groups (all P<0.05) and there was no significant difference of serum potassium and body weight before and after treatment in the two groups (all P>0.05); (4) After treatment of 6 months, LVEF in the treatment group was higher than that in the control group and LVEDD, LVESD, pulmonary artery pressure, NT-pro BNP, and blood pressure in the treatment group were lower than those in the control group (all P<0.05). There was no significant difference of RVED, RAED, serum potassium and body weight between the two groups after treatment (all P>0.05); (5)The difference values before and after treatment of LVEF, LVEDD, LVESD, NT-pro BNP, body weight, systolic blood pressure, and diastolic blood pressure were different between the two groups (all P<0.05); (6)Therapy method ( β=-1.863, 95% CI -2.948-0.777, P=0.001) and residual urine ( β=-1.686, 95% CI -3.079- -0.293, P=0.018) were independent influencing factors of treatment effect (the treatment effect of ARNI was better than that of valsartan; the treatment effect of patients with normal urine volume was better than that of patients with oliguria and anuria). Conclusions:ARNI can effectively improve cardiac function in MHD patients with heart failure, inhibit ventricular remodeling, and improve disease prognosis.
