All patients met complete inclusion and exclusion criteria. Based on the treatment interventions received, they were divided into a control group (n=51) and an observation group (n=52). All patients received percutaneous coronary intervention (PCI) and conventional drug treatment upon admission. The control group received additional treatment with benazepril, while the observation group received Sacubitril/Valsartan on top of the baseline treatment. A comparison was made between the two groups in terms of clinical treatment outcomes, cardiac function indicators [left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDD), left ventricular ejection fraction (LVEF)], levels of inflammatory markers [high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6)], N-terminal pro-B-type natriuretic peptide (NT-proBNP), incidence of adverse reactions, major adverse cardiac events (MACEs), and 6-minute walking distance (6MWD).Results: No patients were lost to follow-up. After six months of treatment, the observation group demonstrated significantly greater improvements in left ventricular function parameters (LVESV, LVEDD, and LVEF) and reductions in inflammatory markers (hs-CRP, IL-6) and NT-proBNP levels compared to the control group (P < 0.05). The observation group also had a significantly lower incidence of major adverse cardiac events (MACEs) (11.54% vs 31.37%, P < 0.05) and a greater improvement in 6-minute walking distance (P < 0.05). The incidence of adverse reactions was comparable between the two groups (P > 0.05).Conclusion: Sacubitril/Valsartan is a safe and effective treatment for heart failure post-AMI, offering significant improvements in cardiac function, inflammatory response, exercise capacity, and a reduction in MACE risk.Keywords: sacubitril/valsartan, heart failure following acute myocardial infarction, efficacy, cardiac function
