Abstract

Purpose: To investigate the clinical effectiveness of the combination of sacubitril and valsartan with conventional therapy in the treatment of patients with heart failure. Methods: This was a retrospective study comprising 100 heart failure patients randomized into study (n = 57) and control groups (n = 43). The study group received sacubitril/valsartan along with conventional drug therapy while control group received only conventional drugs, viz, irbesartan, metoprolol slow release, and furosemide tablets. Echocardiogram showing left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), left anterior descending artery (LAD), N-terminal pro-b-type natriuretic peptide (NT-proBNP), C-reactive protein (CRP), glomerular filtration rate (eGFR), and homocysteine (HCY) of the two groups were compared before and after treatment. Multiple regression was used to analyze the correlation between re-hospitalization and sacubitril/valsartan intervention. Results: The study group showed significantly lower LVEF, LVESD, LVEDD, LAD, NT-proBNP, and homocysteine levels after treatment compared to control group (p < 0.05). Re-hospitalization for abnormal cardiovascular events between the two groups was significantly different in the adjusted Cox proportional hazards regression model. Furthermore, multiple regression analysis showed that sacubitril/valsartan treatment was the independent variable (p < 0.001) Conclusion: Sacubitril/valsartan improves heart function, with reduced incidence of adverse effects without affecting renal function. Further studies are required to validate these findings by expanding sample size, strictly controlling data quality and strengthening follow-up.
