ABSTRACT
Objective: To investigate the efficacy of sacubitril/valsartan in peritoneal dialysis (PD) patients with heart failure with preserved ejection fraction (HFpEF) and its effect on residual renal function. Methods: PD patients with HFpEF in Ningbo First Hospital from March 2018 to August 2021 were retrospectively enrolled and divided into study group with sacubitril/valsartan and control group with valsartan. The clinical baseline data before treatment and clinical indicators during follow-up (6 and 12 months after treatment) were collected and compared between the two groups, and the adverse reactions were also recorded. Results: A total of 99 patients were included in the study. There were 61 patients in the study group, including 44 males and 17 females, with a mean age of (52±13) years. Meanwhile, there were 38 patients in the control group, including 23 males and 15 females, with a mean age of (57±14) years. There was no statistically significant difference in clinical baseline data between the two groups (e.g., age, sex, body mass index, duration of dialysis) (all P>0.05). The N-terminal pro-B-type natriuretic peptide (NT-proBNP) and left ventricular end-systolic dimension (LVDs) were lower, but the left ventricular ejection fraction (LVEF) was higher in the study group than those in the control group at 6 and 12 months after treatment (all P<0.05). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the two groups were lower than baseline values at 6 and 12 months after treatment respectively, with statistically significant differences (all P<0.05). However, there were no statistically significant differences in the decreases of SBP and DBP between the two groups at 6 and 12 months after treatment (all P>0.05). The decrease extents in residual estimated glomerular filtration rate (eGFR) [0.52 (-0.05, 1.19) vs 1.72 (0.97, 2.39) ml·min-1·(1.73 m2)-1, P<0.001]and 24-h residual urine volume [200 (-100, 300) vs 300 (137, 400) ml, P=0.018] at 12 months after treatment were lower in the study group than those in the control group. During the follow-up period, hyperkalemia occurred in 16 cases (26.2%) and 13 cases (34.2%) in the study group and the control group, and hypotension occurred in 3 cases (4.9%) and 1 case (2.6%) in the study group and the control group, respectively. There were no adverse reactions such as cough and angioneurotic edema in the two groups. Conclusions: Sacubitril/valsartan can safely and effectively improve cardiac function and lower blood pressure in PD patients with HFpEF. Compared with valsartan, sacubitril/valsartan may be more beneficial to delay the loss of residual renal function in PD patients with HFpEF.
