RESUMO
To systematically evaluate the efficacy and safety of Xinmailong Injection in the treatment of coronary heart disease complicated with heart failure. Seven databases,namely CNKI, VIP,WanFang,SinoMed,PubMed,EMbase,Cochrane Library, were retrieved by computer for collecting the randomized controlled trials about Xinmailong Injection in the treatment of coronary heart disease complicated with heart failure. The literatures were screened out, data was extracted, and the methodological quality evaluation was conducted by 2 researchers independently according to inclusion and exclusion criteria. RevMan 5.3 software was used for Meta-analysis and corresponding description analysis. A total of 19 studies involving 1 922 patients were included, including 967 cases in the trial group and 955 cases in the control group. All the clinical studies showed a low quality. Meta-analysis results showed that Xinmailong Injection combined with conventional treatment could better reduce the BNP level(SMD=-3.34, 95%CI[-4.06,-2.63]) in patients of coronary heart disease complicated with heart failure or NT-proBNP level, improve the cardiac function(RR=1.23,95%CI[1.18,1.29]) and LVEF(MD=6.85,95%CI[4.93,8.76]),increase 6 MWT(MD=24.34, 95%CI[16.05, 32.64]) and VEGF(MD=26.39,95%CI[24.30,28.49]),and decreased LVEDD(MD=-4.06, 95%CI[-6.33,-1.80]). And subgroup analysis suggested that the course of treatment may be related to the increase of LVEF. This study found that Xinmailong Injection for coronary heart disease complicated with heart failure can further alleviate clinical symptoms and relevant indicators, with no serious adverse reaction. However, it still needs the support of well-designed multicenter, double-blind and high-quality clinical trials.
