Effect of Traditional Chinese Medicine Cutaneous Regions Therapy as adjuvant treatment of chronic heart failure: A systematic review and meta-analysis
Abstract
Objective: To systematically evaluate the effectiveness of Traditional Chinese Medicine Cutaneous Regions Therapy (TCMCRT) as an adjunctive treatment for chronic heart failure. Methods: China National Knowledge Infrastructure (CNKI), Wanfang database, China Science and Technology Journal Database (VIP), Chinese BioMedical Literature Database (CBM), Cochrane Library, PubMed, Web of Science, and EMBASE database were searched to screen randomized controlled trials (RCTs) of TCMCRT for chronic heart failure versus conventional western treatment for chronic heart failure. The Cochrane Risk of Bias Collaboration tool was used to assess the risk of bias in RCTs. Meta-analysis was performed using RevMan 5.3 software to systematically evaluate the effects of conventional western treatment combined with TCMCRT on the cardiac function efficacy, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), N-terminal pro-B-type natriuretic peptide (NT-proBNP), 6-min walk test (6MWT), Minnesota Heart Failure Quality of Life Scale (MLHFQ) and Adverse effects, as well as to evaluate the safety of this treatment modality. Results: 18 RCT studies were finally included, with a total of 1388 patients, including 695 in the experimental group and 693 in the control group. The results of the Meta-analysis showed that the efficacy of improved cardiac function was better in the experimental group than in the control group [RR = 1.24, 95%CI (1.16, 1.32), P < 0.00001]. Improvement of LVEF in the experimental group was better than the control group [MD = 0.04, 95%CI (0.02, 0.05), P < 0.00001]. LVEDD were better in the experimental group than in the control group after treatment [MD = −3.63, 95% CI (−6.14, −1.12), P = 0.005]. The experimental group improved NT-proBNP better than the control group [MD = −586.26, 95%CI (−857.83, −314.68), P < 0.0001]. The experimental group improved 6MWT better than the control group [MD = 38.76, 95%CI (20.77, 56.75), P < 0.0001]. The experimental group improved MLHFQ values better than the control group [MD = −5.93, 95%CI (−7.70, −4.16), P < 0.00001]. Nine of the included studies mentioned the occurrence of adverse reactions, but none reported serious adverse reactions. Conclusion: The available evidence suggests that TCMCRT has good efficacy in the adjuvant treatment of chronic heart failure. However, due to the limitations of this study, more high-quality studies are needed to further validate this conclusion.
