Abstract
Background Chronic heart failure is the main critical illness and cause of death in the later stages of cardiovascular disease, and it is one of the two major challenges in the field of cardiovascular research. The clinical application of traditional Chinese medicine in the prevention and treatment of chronic heart failure has been relatively common in China, and the “Expert Consensus on the Diagnosis and Treatment of Chronic Heart Failure with Integrated Traditional Chinese and Western Medicine” has been published in China. Combining the literature in this field, the authors found that Zhigancao Decoction has been used in the treatment of chronic heart failure with more clinical research reports and higher frequency (this article refers to it as a high-frequency prescription for short). However, Zhigancao Decoction was not included in the recommended prescriptions in the “Expert Consensus on the Diagnosis and Treatment of Chronic Heart Failure with Integrated Traditional Chinese and Western Medicine,” and there was no relevant systematic review and meta-analysis. For this reason, this article has carried out two parts of work, including systematically organizing the literature in this research field and carrying out systematic review and meta-analysis. This can provide stronger evidence support for Zhigancao Decoction combined with conventional Western medicine in the treatment of chronic heart failure and provide a new option for the improvement and update of the “Expert Consensus on the Diagnosis and Treatment of Chronic Heart Failure with Integrated Traditional Chinese and Western Medicine.” Methods This article used the bibliometric method to investigate the research articles on the treatment of chronic heart failure with integrated traditional Chinese and Western medicine and analyzed the high-frequency prescriptions which are used and reported frequently. In addition, we also used manual and computer-aided search methods, the search scope includes CNKI, WANFANG, VIP, SinoMed, Web of Science, PubMed, and Cochrane Library, and the search content is the clinical randomized control of Zhigancao Decoction combined with conventional Western medicine in the treatment of chronic heart failure trials (RCTs). The search period is from the establishment of the database to January 29, 2021. The literature was managed and screened by EndNote software; the quality of the included literature was evaluated according to the modified Jadad scale, and the risk bias was assessed using the Cochrane tool; the results of the included studies were analyzed using the Review Manager 5.3 software; the sources of heterogeneity between the studies were analyzed using Stata16.0 software for sensitivity analysis. Results According to the bibliometric analysis, the maximum number of research reports is 553, which are arranged in descending order of 21 prescriptions, including Zhenwu Decoction, Zhigancao, and powder of five drugs containing poria. The second most frequently used prescription is Zhigancao Decoction combined with conventional Western medicine in the treatment of chronic heart failure, but its systematic review and meta-analysis still need further research. A total of 17 clinical randomized controlled trials of Zhigancao Decoction combined with conventional Western medicine in the treatment of chronic heart failure were included in the search, with a total of 1752 subjects. Meta-analysis results show that Zhigancao combined with conventional Western medicine is more effective than conventional Western medicine in the treatment of chronic heart failure. The advantages are the following 5 outcome indicators: total clinical effective rate, left ventricular ejection fraction, left ventricular end-diastolic diameter, B-type natriuretic peptide, and 6-minute walk test. Conclusions There are many prescriptions combined with Western medicine to treat chronic heart failure, among which Zhigancao Decoction is the second most frequently used prescription. There are many original studies on Zhigancao Decoction combined with conventional Western medicine in the treatment of chronic heart failure. The quality of the evaluation research shows that the overall standard is scientific, and a few experimental designs are slightly irregular. Meta-analysis shows that Zhigancao Decoction combined with conventional Western medicine has better therapeutic effects and safety than conventional Western medicine. This shows the characteristics and advantages of integrated Chinese and Western medicine in the treatment of cardiovascular diseases and is worth recommending.

Chronic heart failure is a complex clinical syndrome caused by ventricular systolic or diastolic disorders caused by abnormal structure or function of the heart. e main symptoms are dyspnea, fatigue, and fluid retention [1, 2]
Based on the medication recommendations in the “Expert Consensus on the Diagnosis and Treatment of Chronic Heart Failure with Integrated Traditional Chinese and Western Medicine”, etc. [16, 17], this article first sorted out the clinical research and systematic review reports of its prescriptions for the treatment of chronic heart failure and selects its commonly used and unreviewed Zhigancao Decoction as the object of in-depth research
