Abstract
BACKGROUND: infarction (AMI) can be reduced by the use of sacubitril/valsartan. However, the therapeutic effects of sacubitril/valsartan in clinical settings are inconsistent. In this paper, the related research on the application of sacubitril/valsartan in AMI was comprehensively searched, in order to explore the clinical efficacy and safety of early application of sacubitril/valsartan after AMI. METHODS: English databases, including American National Library of Medicine, Medline, and Embase, and Chinese databases, including Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure (CNKI), Wanfang, and VIP, were searched using a combination of the following search terms: AMI, acute ST-segment elevation myocardial infarction (STEMI), acute non-ST-segment elevation myocardial infarction (NSTEMI), sacubitril/valsartan sodium tablets, and angiotensin receptor enkephalinase inhibitors. The experimental group was given Sacubitril/Valsartan sodium tablets, while the control group was given angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB). Cochrane Handbook 5.0 risk assessment table were used for quality assessment and bias risk assessment. RESULTS: A total of 5 articles were included in the meta-analysis. The total incidence of adverse cardiovascular events in the sacubitril/valsartan group was significantly lower than that in the control group {relative risk (RR) =0.61 [95% confidence interval (CI): 0.46, 0.82], significance testing Z=3.36, and P=0.0008}. The difference between the rehospitalization rate of the sacubitril/valsartan group and control group was statistically significant [RR =0.67 (95% CI: 0.47, 0.95), significance testing Z=2.23, and P=0.03]. The difference in low blood pressure between the sacubitril/valsartan group and the control group was statistically significant [RR =1.28 (95% CI: 1.18, 1.40), significance testing Z=5.58, and P<0.00001]. The difference in left ventricular ejection fraction (LVEF) between the sacubitril/valsartan group and control group was statistically significant [mean difference (MD) =3.09 (95% CI: 1.69, 4.49), significance testing Z=4.33, and P<0.0001]. DISCUSSION: Sacubitril/valsartan was found to inhibit ventricular remodeling after AMI, improve cardiac function, and reduce the incidence of adverse cardiovascular events after myocardial infarction, the rehospitalization rate, and the mortality rate.
