Abstract:

Objective To analyze the efficacy and safety of low-dose sacubitril/valsartan in the treatment of patients with heart failure complicated with stage 1-3 chronic kidney disease. Methods A total of 72 patients with heart failure and stage 1-3 chronic kidney disease were randomly divided into the two groups. On the basis of conventional anti-heart failure therapy, patients were treated with sacubitril/valsartan 50 mg twice a day. After 1 to 2 weeks, the dosage of the one group was increased to 100 mg twice a day. According to the actual maintenance dose, patients were finally divided into the three groups: the incremental group (100 mg twice a day, 25 cases), the dose maintenance group (50 mg twice a day, 35 cases) and the dose reduction group (25 mg twice a day, 12 cases). The left ventricular ejection fraction (LVEF), N-terminal pro-B-type natriuretic peptide (NT-proBNP), NYHA heart function classification, serum creatinine (Scr), estimated glomerular filtration rate (eGFR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and adverse cardiovascular events were compared before and after treatment between the three groups. Results Compared with before treatment, LVEF increased and NT-proBNP decreased after treatment in the 3 groups (P<0.05). LVEF was higher in the increment group than that in the decrement group and the maintenance group (P<0.05). There were no significant differences in the improvement of NT-proBNP and NYHA cardiac function grading between the 3 groups (P>0.05). Compared with before treatment, the Scr level decreased and eGFR level increased after treatment in the increment group and the maintenance group (P<0.05). There were no significant differences in Scr and eGFR levels before treatment in the decrement group (P>0.05). Compared with before treatment, SBP and DBP decreased after treatment in the 3 groups. DBP was higher in the maintenance group than that in the decrement group and the increment group (P<0.05). None of the patients presented hypotension, severe renal impairment, hyperkalemia and angioedema, and no death occurred. Conclusion Low-dose sacubitril/valsartan is safe and effective in the treatment of patients with heart failure complicated with stage 1-3 chronic kidney disease.
