Evaluation of the safety and efficacy of Zhenwu decoction as adjuvant therapy for the treatment of heart failure with reduced ejection fraction
Medicine(2022)
Abstract
Heart failure with reduced ejection fraction (HFrEF) demonstrates a substanital threat to global public health. Several Chinese studies have been conducted to date evaluating the clinical efficacy of Zhenwu decoction (ZWD) as a treatment for HFrEF. The present systematic review will be conducted to more comprehensively evaluate the impact of ZWD on HFrEF outcomes.For this systematic review, all randomized controlled trials (RCTs) reporting on the effectiveness of ZWD as a treatment for HFrEF published as of December 30, 2021 in the Embase, PubMed, Springer, Web of Science, Cochrane Library, China Biomedical Literature Database, China National Knowledge Infrastructure, and the Wan-Fang databases will be identified without any language or publication restrictions. Two researchers will independently choose investigations, extract information, and gauge research quality. Primary outcomes of interest will include all-cause mortality and HF-associated mortality. Secondary outcomes will include the incidence of adverse events, ultrasonic cardiographic indices (including left ventricular ejection fraction and left ventricular mass index), New York Heart Association grade, N-terminal pro-b-type natriuretic peptide, B-type natriuretic peptide, and 6-minute walking distance. RevMan v 5.3 will be used to conduct meta-analyses where possible, with descriptive or subgroup analyses otherwise being conducted. Data will be given as risk ratios for categorical variables and mean difference for continuous variables.This comprehensive protocol will aid in the systematic and objective evaluation of the efficacy and safety of ZWD as a treatment for HFrEF, providing a scientific basis for the clinical utilization of ZWD.
