A Comparative Analysis of the Clinical Efficacy of Sacubitril Valsartan Sodium and Enalapril in Patients with Non-Valvular Ejection Fraction Reduction in Heart Failure.

Objective: Heart failure is a common cardiovascular disease, and its prevalence is increasing year by year. For patients with heart failure combined with non-valvular reduced ejection fraction, drug therapy has always been a key treatment. This study aimed to explore the clinical efficacy of sacubitril valsartan sodium and enalapril in such patients.

Methods: Study design: This study used a prospective observational design. From February 2020 to February 2022, we included 123 patients with non-valvular heart failure and reduced ejection fraction who were treated in Xingtai Third Hospital. Patients were divided into two groups according to the treatment plan: Group A (n=61) received enalapril, and Group B (n=62) received nifedipine. All patients received conventional treatment. We compared the efficacy of the two groups of patients 8 weeks after treatment. During the study, the laboratory indicators, echocardiographic indicators, cardiovascular markers, and possible adverse reactions of the two groups of patients before and after treatment were recorded.

Results: After 8 weeks of treatment, the effective rate of group B was higher than group A (P < .05). There were no differences in the levels of total protein, total bilirubin, total cholesterol and serum creatinine between the two groups before and after treatment (P > .05). The serum creatinine level in the two groups after treatment was higher than that before treatment, and the level in group B was lower than that in group A (P < .05). There were no statistically significant differences in the levels of total protein, total bilirubin and total cholesterol between the two groups before and after treatment (P > .05), and there was no statistically significant difference in the level of serum creatinine between the two groups before treatment (P > .05), and the level of serum creatinine after treatment was higher than that before treatment, and the level of group B was lower than that of group A (P < .05). Before treatment, there was no significant difference in the levels of high-sensitive troponin T and n-terminal brain natriuretic peptide and cyclic guanosine phosphate between the two groups (P > .05). After treatment, the levels of high-sensitive troponin T and N-terminal brain natriuretic peptide in the two groups were lower than those before treatment, and those in group B were lower than those in group A. The level of cyclic guanosine phosphate in group A was lower than that before treatment, the level of cyclic guanosine phosphate in group B was higher than that before treatment, and the level of group B was higher than that of group A (P < .05). The incidence of adverse cardiovascular events in group B was lower than that in group A (P < .05).In this study, the effective rate of treatment group B was significantly higher than that of treatment group A, indicating that treatment group B had a better therapeutic effect. In addition, there were no significant differences between the two groups in a series of biochemical parameters, but it is worth noting that after treatment, the serum creatinine level of group B was significantly lower than that of group A, which may indicate that the treatment of group B is not only more effective but also Reduces the risk of certain adverse cardiovascular events.

Conclusion: The main findings of the study showed that Sacubitril valsartan sodium showed better clinical efficacy than enalapril in patients with heart failure and non-valvular reduced ejection fraction. Specifically, the drug significantly improved patients' kidney function, reduced cardiovascular marker levels, and reduced the incidence of adverse cardiovascular events. These findings have important clinical implications for guiding treatment selection in patients with heart failure.
