The efficacy and safety of xuesaitong injection combined with western medicines in the treatment of ischemic stroke: An updated systematic review and meta-analysis

Abstract

Background: Due to constantly emerging new studies on Xuesaitong injection (XST) agent, it is necessary to summarize and analyze the latest published clinical research data to re-evaluate the clinical efficacy and safety of XST. This study mainly aimed to evaluate the clinical efficacy and safety of XST combined with western medicines (WM) for ischemic stroke treatment. Methods: The related databases were searched to collect all randomized controlled trials (RCTs) comparing the combination of XST and WM with WM alone for the treatment of patients with ischemic stroke. Participant, intervention, comparison, outcome and study type (PICOS) was the inclusion criteria of all studies. The search for and data extraction of the included studies was performed by 2 researchers, who then conducted quality evaluation. The Cochrane Collaboration’s risk of bias tool was used for the article evaluation. The software RevMan 5.3 and Stata 15.0 were used for pooled analysis. Results: A total of 12 RCTs were included involving 1,769 patients with ischemic stroke, which combined XST with WM therapy. Moreover, the funnel plot showed that there was no obvious publication bias in the included studies. Meta-analysis showed that the total effective rate in the XST combined with WM group was higher than that in the WM alone group [odds ratio (OR) =4.04, 95% confidence interval (CI): 2.86 to 5.73, P<0.001]. The National Institutes of Health Stroke Scale (NIHSS) score in the XST combined with WM group was significantly lower than that in the WM alone group [weighted mean difference (WMD) =−3.17, 95% CI: −4.14 to −2.20, P<0.001]. In addition, XST combined with WM significantly reduced the plasma viscosity, fibrinogen level, whole blood high shear viscosity, and whole blood low shear viscosity in patients with ischemic stroke (P<0.01). For the comparison of adverse reactions, the results showed that the adverse reactions among patients with ischemic stroke in the XST combined with WM group and in the WM group did not differ significantly. Discussion: Compared with single WM medication, XST combined with WM improves the total clinical effective rate, promotes the recovery of patients’ neurological function, and has few adverse reactions and high safety in clinical application.
