Abstract:
To systematically review the adjuvant effects of Zhenyuan capsule on improving the cardiac function of patients with chronic heart failure. Databases including PubMed, EMbase, the Cochrane Library, CBM, CNKI, VIP and Wanfang Data were searched electronically from inception to October 2016 to collect randomized controlled trials (RCTs) about Zhenyuan capsule for adjuvant treatment of chronic heart failure. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 14 RCTs involving 1 204 patients were included. The results of Meta-analysis showed that the Zhenyuan capsule group had significantly better effectiveness in cardiac function (RR=1.27, 95%CI 1.20 to 1.35, P < 0.000 01), stroke volume (WMD=7.62, 95%CI 6.39 to 8.84,P < 0.000 01), scores of HAMA (WMD=-4.16, 95%CI -5.59 to -2.72, P < 0.000 01), psychological effect of HAMA (RR=1.47, 95%CI 1.15 to 1.89, P=0.002), and traditional Chinese medical syndrome (RR=1.46, 95%CI 1.25 to 1.72, P < 0.000 01) than those of the control group, with statistically significant differences. Current evidence showed that Zhenyuan capsule combined with routine treatment could improve the cardiac function and quality of life of patients with chronic heart failure, and with high safety. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.
