ABSTRACT
Objective: To evaluate the efficacy and safety of Qishen Yiqi dropping pills in the treatment of chronic heart failure. Method: Eight databases were searched at home and abroad, and the randomized controlled trials of Qishen Yiqi dropping pills in the treatment of chronic heart failure were screened. Literature quality of the included studies was evaluated by the bias risk assessment tool of Cochrane collaboration network, and the Meta-analysis was performed by RevMan 5.3 software. Result: A total of 606 related literature were retrieved, and 11 studies were eventually included, involving 931 patients. The quality of the included literature was generally low. Meta-analysis results showed that efficacy of Qishen Yiqi dropping pills combined with conventional western medicine was better than conventional western medicine alone in improving B-type natriuretic peptide[weighted mean difference (WMD)=-29.47, 95% confidence interval (CI) (-37.29,-21.64), PPPP=0.005], 6-minute walk test[WMD=50.13, 95%CI (22.32, 77.93), P=0.000 4]. In terms of safety indicators, one study intended to observe safety indicators, but it was not reported in the actual literature, and the remaining studies did not find adverse reactions of Qishen Yiqi dropping pills combined with conventional western medicine. Conclusion: The results of this study support the clinical use of Qishen Yiqi dropping pills combined with conventional western medicine in the treatment of chronic heart failure, but in view of the limitations in the quantity and quality of clinical studies, the positive results are only used as a reminder and reference for clinical diagnosis and treatment. In the future, more high-quality researches are needed to further confirm its efficacy.
