Effect of Emergency Percutaneous Coronary Intervention Combined with Sacubitril and Valsartan on the Cardiac Prognosis in Patients with Acute Myocardial Infarction.

Purpose: This study aimed to investigate the effect of emergency percutaneous coronary intervention (PCI) combined with sacubitril-valsartan (Entresto) on the cardiac prognosis in patients with acute myocardial infarction (AMI).

Patients And Methods: A total of 78 AMI patients who were treated in our hospital between January 2020 and September 2021 were included and randomly divided into treatment group and control group (n=39 per group). In the control group, patients were treated with primary PCI combined with irbesartan; in the treatment group, patients were treated with primary PCI combined with Entresto; pharmacotherapy lasted for 3 months. The left ventricular remodeling indexes, serum N-terminal B-type natriuretic peptide precursor (NT-proBNP), serum homocysteine (HCY), cystatin C (CysC) and results of 6-minute walk test (6MWT) before and after treatment were compared between two groups. The incidence of major adverse cardiovascular events (MACE) was determined and compared between them.

Results: (1) Before treatment, there were no marked differences in the left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), interventricular septum thickness (IVST), NT-proBNP, left ventricular ejection fraction (LVEF), HCY, CysC, and results of 6MWT between two groups (P>0.05). After treatment, the LVEDS, LVEDD, NT-proBNP, HCY and CysC in the control group were significantly higher than in the treatment group (P<0.05). The recovery of LVEF and 6MWT in the treatment group was significantly better than in the control group (P<0.05). After treatment, there was no significant difference in the IVST between two groups (P>0.05). (2) The incidence of MACE in the control group was significantly higher than in the treatment group (P<0.05).

Conclusion: Compared with irbesartan, Entresto can further improve the cardiac function, prevent ventricular remodeling, and further optimize the clinical efficacy of PCI in AMI patients.
