OBJECTIVE： To evaluate the therapeutic efficacy and safety of Shenmai injection in adjuvant therapy of angina pectoris， and to provide evidence-based reference in clinic. METHODS： Retrieved from CJFD， Wanfang database， VIP and PubMed， randomized control trials （RCTs） about Shenmai injection combined with routine plan （trial group） vs. routine plan sole （control group） in the treatment of angina pectoris were collected. Meta-analysis was conducted by using Rev Man 5.3 statistical software after data extraction and quality evaluation with Cochrane systematic evaluator manual 5.1.0. RESULTS： A total of 25 studies were included， involving 2 093 patients. Meta-analysis showed that clinical efficacy rate [RR＝1.31，95％CI（1.25，1.37），P＜0.001] and ECG total response rate [RR＝1.42，95％CI（1.31，1.54），P＜0.001] of trial group were significantly higher than those of control group， with statistical significance. Results of subgroup analysis showed that among high-dose subgroup（＞40 mL/d） and low-dose subgroup（≤40 mL /d）， clinical efficacy rate [high dose： RR＝1.26，95％CI（1.19，1.34），P＜0.001； low dose： RR＝1.36，95％CI（1.27，1.45），P＜0.001] and ECG total response rate [high dose： RR＝1.39，95％CI（1.22，1.60），P＜0.001； low dose： RR＝1.43，95％CI（1.30，1.58），P＜0.001] of trial group were significantly higher than those of control group， with statistical significance. There was no statistical significance in the incidence of ADR between 2 groups [RR＝0.66，95％CI（0.32，1.40），P＝0.28]. CONCLUSIONS： Shenmai injection in adjuvant therapy of angina pectoris shows good therapeutic efficacy and safety in the treatment of angina pectoris. It is suggested to its clinical application start from the low dose.
