Objective: To assess the efficacy and safety of the initiation of sacubitril-valsartan (ARNI) therapy, as compared with ACEI therapy, after hemodynamic stabilization among patients hospitalized for acute decompensated heart failure (ADHF). Methods: A total of 199 hospitalized patients for ADHF in our department from January 2017 to June 2019 were included in this retrospective analysis. According to the medication early after hemodynamic stabilization, patients were divided into ARNI group ( n =92) and ACEI group ( n =107). Among the included patients, 61 patients with newly diagnosed heart failure at the time of admission were also divided into ARNI group ( n =30) and ACEI group ( n =31) according to the applied medication. Clinical baseline data and follow-up results of enrolled patients were collected through the electronic medical records at admission, outpatient and telephone follow-up. The primary effectiveness observation index was left ventricular ejection fraction (LVEF) and left ventricular end diastolic dimension (LVEDD) measured by echocardiography; the secondary observation index was death from any causes and hospitalization for heart failure. Safety outcomes were the incidences of symptomatic hypotension, worsening renal function, hyperkalemia, and angioedema. Results: The clinical baseline characteristics were similar between ARNI group and ACEI group(all P >0.05). The duration of follow up was (15.2±6.5) months in all patients enrolled, (12.3±5.0) months in ARNI group, and (18.2±6.5) months in ACEI group. At the end of follow-up, prevalence of an absolute LVEF increase of more than 5% was 48.9% (45/92) in ANRI group and 25.2% (27/107) in ACEI group ( P =0.001). Percent of LVEF increase to more than 50% was 17.4% (16/92) in ANRI group and 3.7% (4/107) in ACEI group ( P =0.001). Percent of patients with more than 10 mm LVEDD reduction was 14.1% (13/92) in ANRI group and 3.7% (4/107) in ACEI group ( P =0.009). All-cause mortality rate was 5.7% (5/88) in ARNI group and 15.3% (13/85) in ACEI group ( P =0.038). Rate of re-hospitalization due to heart failure was 50% (46/92) in ARNI group and 71% (76/107) in ACEI group( P =0.002).The rates of symptomatic hypotension, worsening renal function, hyperkalemia, and angioedema were similar between ARNI group and ACEI group (all P >0.05). In patients with first diagnosed heart failure,percent of LVEF increase to more than 50% was 30% (9/30) in ANRI group and 6.5% (2/31) in ACEI group ( P =0.017). Percent of more than 10 mm LVEDD reduction was 26.7%(8/30) in ANRI group and 3.2%(1/31) in ACEI group ( P =0.012). Percent of an absolute LVEF increase of more than 5% was 53.3% (16/30) in ANRI group and 51.6% (16/31) in ACEI group ( P =0.893). Re-hospitalization due to heart failure was 23.3% (7/30) in ARNI group and 73.3% (11/31) in ACEI group( P <0.01). Rate of all-cause death tended to be lower in patients receiving ARNI (3.4% (1/29)) as compared to patients receiving ACEI (13.0% (3/23), P =0.197). Conclusions: Among patients with heart failure with reduced ejection fraction hospitalized for ADHF, the initiation of ARNI therapy after hemodynamic stabilization is associated with a more significant improvement of cardiac remodeling and pump function than ACEI therapy and satisfactory safety. In ADHF patients with first diagnosed heart failure, initiation of ARNI therapy after hemodynamic stabilization can more effectively improve cardiac remodeling and pump function than treatment with ACEI.
