Background: Coronary heart disease angina is a very common cardiovascular disease, which not only causes personal health problems, but also a serious burden on the social economy. Xuefu Zhuyu Decoction (XFZYD) has been widely adapted to clinical practice for people with coronary heart disease angina. At present, it is necessary to update the existing research, re-evaluate the effectiveness and safety of XFZYD, and provide the latest evidence for coronary heart disease angina.
Methods and analysis: The purpose of this study was to search the electronic database for XFZYD in the treatment of coronary heart disease angina. The database includes PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure database (CNKI), Wanfang database, Chinese Biomedical Literature database (CBM), Chinese Scientific Journal database (VIP). In addition, ongoing trials will be retrieved from the WHO ICTRP Search Portal, the Chinese Clinical Trial Register and The Clinical Trials Register. We will assess all the documents from the database establishment to January 31, 2019. The RevMan V.5.3 software will be used to calculate the data synthesis and perform a meta-analysis when the literature is appropriate.
Results: The study will provide a high-quality synthesis of current evidence of XFZYD for coronary heart disease angina from the various comprehensive assessment, including Significantly effective, Effective, Invalid, Aggravation, which based on the "Guidelines for Clinical Research of New Chinese Medicine". Adverse events are also included.
Conclusion: The systematic review will provide evidence for assessing the effectiveness and safety of XFZYD in the treatment of coronary heart disease angina.
