Evidence quality assessment of sodium tanshinone IIA sulfonate injection intervention coronary heart disease angina pectoris: An overview of systematic reviews and meta-analyses.

Abstract

Sodium tanshinone IIA sulfonate injection (STS) is widely used in the clinical treatment of coronary heart disease angina pectoris (CHDAP). This article systematically summarizes and evaluates the available evidence for STS in the treatment of AP, and assess its quality. Two researchers searched and extracted 8 databases for systematic reviews (SRs)/meta-analyses (MAs), and independently assessed the methodological quality, risk of bias, reporting quality, and quality of evidence of SRs/MAs included in randomized controlled trials (RCTs). Tools used included the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the risk of bias in systematic (ROBIS) scale, the list of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. This overview includes 11 SRs/MAs that use quantitative calculations to comprehensively evaluate various efficacies of STS in AP intervention. The methodological quality, reporting quality, risk of bias, and quality of evidence for outcome measures of SRs/MAs were all unsatisfactory. All SRs/MAs are of low quality according to the results of the AMSTAR-2 assessment, and only a small number of SRs/MAs were assessed as low risk of bias based on the results of the ROBIS assessment, and none of the SRs/MAs has been fully reported on the checklist. According to GRADE system, 33 outcomes were extracted from the included SRs/MAs for evaluation, of which 12 were rated as moderate-quality evidence, 7 as low-quality evidence, and 14 as very low-quality evidence. Limitations included the lack of essential items such as protocol registration, screening of duplicate studies, provision of a list of excluded studies and assessment of publication bias. Tanshinone IIA Sulfonate Sodium Injection may be an effective and safe treatment method. However, further standardized, comprehensive SRs/MAs and RCTs are needed to provide evidence-based medical support.
