Abstract: Objective  To investigate the clinical efficacy of sacubitril/valsartan in maintenance hemodialysis (MHD) patients with heart failure.  Methods  A retrospective cohort study was performed in the MHD patients with heart failure treated in Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from January 1, 2020, to July 31, 2021. Patients who took the medicine for more than 3 months were included in this study. Clinical data, demographic characteristics, laboratory indicators, echocardiography, adverse response of the treatment, and endpoint events were recorded.  Results  A total of 54 patients were enrolled and followed up for 3 months. Sacubitril/valsartan treatment significantly reduced NT-proBNP (15213.15±12110.44 vs. 7823.21±7457.71ng/L, t=7.053, P＜0.001), interventricular septal thickness dimension (IVSTd; 10.24±1.81 vs. 9.79±1.96mm, t=2.557, P=0.013), left ventricular posterior wall thickness dimension (LVPWTd; 10.04±1.69 vs. 9.44±1.61mm, t=2.728, P=0.009), left ventricular mass index (LVMI; 126.30±42.79 vs. 113.81±34.74g/m2, t=3.059, P=0.003), systolic blood pressure (SBP; 160.46±16.43 vs. 139.19±15.21mmHg, t=12.381, P＜0.001) and diastolic blood pressure (DBP; 79.57±11.97 vs. 69.67±10.43mmHg, t=7.070, P＜0.001). Meanwhile, left ventricular ejection fraction (LVEF) increased after three months of the treatment (55.76±8.30% to 60.02±6.18%, t=-4.323, P＜0.001). There were no significant differences in dry body mass (t=0.465, P=0.644), body mass gain (t=0.350, P=0.728), ultrafiltration (t=-0.019, P=0.985), parathyroid hormone (PTH, t=-1.660, P=0.103), serum creatinine (Scr, t=-1.452, P=0.152), Kalium (K, t=-1.806, P=0.077), Natrium (Na, t=0.400, P=0.690), Calcium (Ca, t=-1.376,  P=0.175), Phosphorus (P, t=-0.193, P=0.848), hemoglobin (HGB, t=-0.710, P=0.481) and albumin (ALB, t=-1.823, P=0.074) before and after the treatment.  Conclusion  Sacubitril/valsartan could effectively and safely relieve the clinical symptom of heart failure, improve cardiac function indicators, reduce left ventricular hypertrophy, reverse left ventricular remodeling, and lower blood pressure in MHD patients with heart failure.
