Abstract 【Objective】 To investigate the clinical efficacy of sacubitril valsartan sodium combined with atorvastatin in patients with acute ST-segment elevation myocardial infarction (STEMI) complicated with heart failure (HF). 【Methods】 A total of 80 patients with STEMI complicated with HF admitted to our hospital from June 2022 to October 2024 were enrolled and randomly divided into a control group and an observation group using a random number table, with 40 cases in each group. The control group received atorvastatin calcium tablets on the basis of conventional treatment, while the observation group was additionally given sacubitril valsartan sodium tablets on the basis of the control group. Clinical efficacy, cardiac function indexes [left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD)], oxidative stress indexes [superoxide dismutase (SOD), malondialdehyde (MDA)], myocardial injury markers [N-terminal pro-brain natriuretic peptide (NT-proBNP), creatine kinase isoenzyme (CK-MB), cardiac troponin I (cTnI)], vascular endothelial function indexes [vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), nitric oxide (NO)], myocardial energy metabolism indexes [free fatty acid (FFA), circumferential end-systolic wall stress (cESS), myocardial energy expenditure (MEE)], and the incidence of adverse reactions were compared between the two groups. 【Results】 The total effective rate of the observation group was significantly higher than that of the control group (P<0.05). After treatment, LVEF in both groups was increased, while LVESD and LVEDD were decreased compared with baseline; the observation group had higher LVEF and lower LVESD and LVEDD than the control group (all P<0.05). MDA was decreased and SOD was increased in both groups, with lower MDA and higher SOD in the observation group (P<0.05). Levels of NT-proBNP, CK-MB and cTnI were all reduced in both groups, and were lower in the observation group (P<0.05). Levels of NO and VEGF were elevated while ET-1 was reduced in both groups, with higher NO and VEGF and lower ET-1 in the observation group (P<0.05). FFA, cESS and MEE were decreased in both groups, and were lower in the observation group (P<0.05). The incidence of adverse reactions in the observation group was lower than that in the control group (P<0.05). 【Conclusion】 Sacubitril valsartan sodium combined with atorvastatin shows favorable clinical efficacy in STEMI patients complicated with HF. It can regulate oxidative stress and myocardial energy metabolism, protect cardiomyocytes and vascular endothelial function, and presents good safety.
