A Retrospective Study of Whether Sacubitril-Valsartan Improves Cardiac Function in Patients with Acute Coronary Syndrome and Hypertension after Percutaneous Coronary Intervention

Objectives: This study aimed to explore the effect of sacubitril-valsartan on cardiac function in patients with acute coronary syndrome (ACS) and hypertension after percutaneous coronary intervention (PCI). Methods: The study was conducted on 166 patients with ACS and hypertension who underwent PCI at our hospital from July 2022 to June 2023. The patients were divided into two groups: an observation group and a control group, with 83 cases in each group. The observation group was given sacubitril- valsartan, and the control group was given enalapril. The treatment period was 3 months. The cardiac function indexes, biochemical indexes, adverse reactions, and the occurrence of new cardiovascular and cerebrovascular events were compared between the two groups before and after medication. Results: We found no statistically dramatic differences between the two groups in gender, age, body mass index, diabetes, hyperlipidemia, family history of ACS, family history of hypertension, smoking history, drinking history, regular exercise history, low-salt and low- fat diet, New York Heart Association cardiac function classification, number of vessels involved in coronary artery disease, stent length, stent inner diameter, number of stent implants, duration of hypertension, medication time, use of antihypertensive drugs, systolic blood pressure (SBP), and diastolic blood pressure (DBP). The observation group had lower left ventricular end-diastolic internal diameter (LVEDD) levels, higher left ventricular ejection fraction (LVEF) levels, and lower left ventricular end-systolic internal diameter (LVESD) levels compared with the control group. The levels of N-terminal pro-brain B-type natriuretic peptide (NT-proBNP), cardiac troponin I (cTnI), and creatine kinase isoenzyme MB (CK-MB) in the observation group decreased compared with those in the control group. Compared with the pre-medication period, LVEDD levels decreased, LVEF levels increased, and LVESD levels decreased in the observation and control groups, whereas NTproBNP, cTnI, and CK-MB levels decreased in the observation and control groups. The total incidence rates of adverse reactions and new cardiovascular and cerebrovascular events in the observation group were found to be lower than those in the control group. Conclusion: The application of sacubitril-valsartan in patients with ACS complicated with hypertension after PCI can effectively improve patients' cardiac function, reduce biochemical indexes related to myocardial injury, and lower the incidence of adverse cardiovascular events. It features good safety, providing a new treatment strategy and method for patients with ACS complicated with hypertension.
