Methods The related databases of CNKI, CBM, VIP, Wanfang Database, PubMed and Cochrane library were used to identify studies on the efficacy and safety of enalapril folic acid tablets vs enalapril tablets in the treatment of heart failure. The NT-proBNP, Hcy, serum levels of copeptin, cardiac ultrasound index and ADR of studies were analyzed by the RevMan 5.3 software. Results A total of 12 randomized controlled trials were reviewed, and 1 259 patients were included. Meta-analysis result showed that:compared with enalapril tablets, enalapril folic acid tablets further reduced the levels of NT-proBNP (MD=-0.41, 95%CI=-0.43--0.40, P<0.01), serum levels of copeptin (MD=-3.02, 95%CI=-4.37--1.68, P<0.01) and Hcy levels (MD=-3.36, 95%CI=-4.04--2.68, P<0.01); And it significantly increased LVEF/% (MD=5.00, 95%CI=3.58-6.43, P<0.01), and decreased LVEDD (MD=-4.07, 95%CI=-5.74--2.40, P<0.01) and LVESDD (MD=-3.49, 95%CI=-5.23--1.76, P<0.01). The rate of ADR had no significant difference (OR=1.00, 95%CI=0.42-2.36, P> 0.05). Conclusion Enalapril folic acid tablets can reduce the levels of NT-proBNP, Hcy and serum levels of copeptin, and improve cardiac function in patients with heart failure than that of enalapril tablets. The safety of the two drugs is equivalent."/>
