BackgroundShenfu Injection (SFI) is a promising alternative treatment for heart failure (HF) in China. Many complete clinical trials have examined the efficacy of SFI combined use with conventional treatment (CT) vs CT alone. This study is to conduct a systematic review and meta-analysis of randomized clinical trials to evaluate the benefits and risks of using SFI in addition to CT for the treatment of HF.MethodAll the trials will be searched through 4 English databases (MEDLINE via PubMed, the Cochrane Library, EMBASE, Web of Science) and 4 Chinese databases (the China Science and Technology Journal Database, Chinese Biomedical Literature Database, Wan-fang Database, the China National Knowledge Infrastructure.) from October 2005 to June 2019. Conference articles or articles with incomplete data will be removed. The primary outcome was the New York Heart Association, 6-minute walk test, hospitalization or rehospitalization. Left ventricular ejection fraction percentage, left ventricular end-diastolic dimension, Cardiac index, heart rate, N-terminal pronatriuretic peptide and other indicators were also assessed. RevMan V.5.3 Software and Stata 13.0 Statistics Software were used to calculate the data synthesis and conduct meta-analysis according to the guideline of Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols 2015.ResultsMortality, New York Heart Association function classification, heart rate, 6-minute walk test, hospitalization or rehospitalization, Heart rate, systolic blood pressure, DBP, Cardiac minute volume, left ventricular ejection fractions percentage, left ventricular end-diastolic dimension (mm), N-terminal pronatriuretic peptide, etc. and adverse effects will be comprehensively assessed to evaluate the adjunctive effect of SFI through different aspects. We will perform a meta-analysis of each outcome with subgroup analysis based on the type of HF, treatment methods, and course of disease. Sensitivity analysis will be conducted with clinical factors, treatment methods, methodological characteristics, and statistical heterogeneity (if applicable).ConclusionThis study will assess the adjunctive effect of SFI and its safety on HF with clinical evidence.Prospero Registration NumberPROSPERO CRD42020151856.Copyright © 2021 the Author(s).
