AbstractSacubitril/valsartan is an angiotensin receptor neprilysin inhibitor (ARNI) that has been shown in multiple clinical trials to have clinical benefits and is recommended by major clinical management guidelines as a first-line treatment for heart failure with reduced ejection fraction (HFrEF). The most significant benefit that was observed in clinical trials is its effect in reducing hospital readmissions. However, little evidence supports its effectiveness in practice, especially in Saudi Arabia. A multicenter retrospective cohort study was conducted using the patient medical records at 2 tertiary hospitals in Saudi Arabia. Eligible patients were adults (≥18 years old) with a confirmed diagnosis of HFrEF who were discharged on either sacubitril/valsartan or angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) in addition to the other recommended therapy for HFrEF. The primary endpoint was the all-cause 30-day readmission rate. The secondary endpoints included all-cause readmissions at 60-day, 90-day, and 12 months. Additionally, 30-day, 60-day, and 90-day readmissions due to HF were evaluated. A total of 398 patients were included in our analysis; 199 (50.0%) received sacubitril/valsartan (group 1), and 199 (50.0%) received ACEI/ARB (group 2). Our results showed that all-cause 30-day readmissions in group 1 were significantly lower than in group 2 (7% vs 25.0%, RR 0.28, 95% Cl 0.16-0.49; P < .001). Additionally, the secondary outcomes showed significantly fewer 60-day, 90-day, and 12-month all-cause readmissions were identified in group 1 compared to group 2 (11% vs 30.7%, RR 0.36, 95% CI 0.23-0.56; P < .001), (11.6%. vs 32.6%, RR 0.35, 95% CI 0.23-0.55; P < .001) and (23.6% vs 51.2%, RR 0.46, 95% CI 0.35-0.62; P < .001), respectively. Furthermore, HF readmissions at 30-day, 60-day, and 90-day in group 1 were significantly lower than in group 2 (P < .05). Sacubitril/valsartan for the treatment of HFrEF is associated with a significantly lower rate of all-cause readmission as well as HF readmissions compared to ACEI/ARB. These benefits extend up to 12 months post-discharge.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
