Analysis of the effect of Lyophilized Recombinant Human?Brain Natriuretic Peptide on Endothelial Function in patients with acute myocardial infarction

摘要

Objective: This study aims to analyze the effect of lyophilized recombinant human brain natriuretic peptide on the endothelial function of patients with acute myocardial infarction. Methods: One hundred and thirty-six patients with acute myocardial infarction in our hospital were randomly divided into a control group and an experimental group (68 cases each). The patients in the control group were treated by conventional treatment. The patients in the experimental group were treated with lyophilized recombinant human brain natriuretic peptide besides the conventional treatment. The levels of flow-mediated dilatation (FMD), serum nitric oxide (NO), and endothelin-1 were compared between the two groups before and after treatment. Results: Before treatment, there was no significant difference between the two groups in the level of FMD (P0.05); after treatment, the level of FMD in the experimental group was higher than that in the control group, and the difference was statistically significant (P0.05); after treatment, the levels of serum NO and endothelin-1 in the experimental group significantly improved, which were better than those in the control group (P0.05). Conclusion: Lyophilized recombinant human brain natriuretic peptide can improve the FMD, increase the content of NO in the blood, and effectively reduce the level of endothelin-1, which is of great significance to improve the endothelial function of patients with acute myocardial infarction and is worth clinical application. doi: https://doi.org/10.12669/pjms.37.1.2706 How to cite this:Wang B, Xu H, Li C, Wang X, Sun W, Li J.
