The efficacy of glyceryl trinitrate for acute intracerebral hemorrhage: A systematic review and meta-analysis.

ABSTRACT

Current research on the effects of glyceryl trinitrate (GTN) on the lowering of elevated blood pressure (BP) among patients with acute intracerebral hemorrhage (AIH) has not been highly emphasized. The aim of this meta-analysis is to examine the effects of GTN in patients with acute stroke. The lowering of BP was the primary outcome measure in patients treated with GTN compared to no-GTN treatment. A meta-analysis was performed to evaluate the efficacy of GTN in lowering BPs and analyze the outcomes of GTN treatment. Appropriate articles were searched using PubMed, Taylor & Francis Online, Cochrane, Scopus, ScienceDirect, Wiley Online Library, and Springer, with the use of appropriate keywords as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Out of 13 articles eligible for this study, 7 studies qualified for the meta-analysis by meeting the inclusion criteria. The PRISMA guidelines and the recommendations of Cochrane Collaboration were followed when conducting this meta-analysis. After subgroup analysis, differences between patients treated with GTN and without GTN were analyzed. The lowering of BP resulted in improved functional outcomes in patients treated with GTN. This meta-analysis showed differences between the 2 groups, with a risk ratio (RR) of 1.01 (95% confidence interval (95% CI) 0.92-10.07, p = 0.30, I2 = 18%). There was a significant improvement in outcome measures in patients treated with GTN by lowering elevated BP after acute stroke.
