The Value of Sacubitril/Valsartan in Acute Anterior Wall ST-Segment Elevation Myocardial Infarction before Emergency Percutaneous Coronary Intervention

Many patients present with heart failure with reduced ejection fraction (HFrEF) after acute anterior wall ST-segment elevation myocardial infarction (STEMI). The purpose of this study was to evaluate the effect of preprocedural sacubitril/valsartan on N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and left ventricular ejection fraction (LVEF) in patients with acute anterior STEMI undergoing percutaneous coronary intervention (PCI).We enrolled patients with acute anterior wall STEMI who underwent emergency PCI at The Affiliated Hospital of Putian University from January 2019 to January 2021. Prior to PCI, patients were randomized to receive sacubitril/valsartan or valsartan. Nonculprit lesion vessels that require PCI were excluded. The primary endpoints included changes in NT-pro-BNP, LVEF, and rehospitalization for heart failure (HF) during the follow-up period.Out of 109 patients who were randomized, 55 were assigned to receive sacubitril/valsartan and 54 were assigned to receive valsartan. The decrease in NT-pro-BNP concentrations and the increase in LVEF were significantly greater in the sacubitril/valsartan group than in the valsartan group.In patients with acute anterior wall STEMI undergoing emergency PCI, preprocedural initiation of sacubitril/valsartan therapy increased LVEF and lower NT-pro-BNP concentrations compared with valsartan therapy.
