Efficacy and Safety of Stellate Ganglion Block for Treating Angina Pectoris: A Systematic Review and Meta-Analysis
Abstract
Purpose: This systematic review and meta-analysis of randomized controlled trials (RCTs) is aimed at assessing the clinical efficacy and safety of stellate ganglion block (SGB) for angina pectoris (AP). Methods: PubMed, Embase, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang databases were comprehensively searched for RCTs investigating SGB treatment for AP. The retrieval time was from the establishment date of each database to October 10, 2024. The Cochrane risk of bias assessment tool was used to determine the methodological quality. Review Manager 5.4 software was employed for data analysis, and GRADEpro GDT software was utilized to evaluate the quality of evidence. Results: Ultimately, six RCTs were included, encompassing 373 patients with angina. The overall methodological quality of the included studies was moderate, with the evaluation of evidence quality showing 12 low-quality and five extremely low-quality studies. The meta-analysis results demonstrated that compared with the control group, the experimental group had lower frequency and duration of AP, visual analog scale score, heart rate, detection rate of S-T segment elevation ≥ 0.1 mV on electrocardiogram (ECG) after 24 h of treatment, detection rate of abnormal T waves on ECG after 24 h of treatment, and S-T segment displacement on ECG after treatment. Furthermore, the experimental group exhibited lower serum Cardiac…
