[Systematic evaluation on efficacy and safety of Gingko Ketone Ester Dropping Pills in treatment of angina pectoris and coronary heart disease].

To systemically evaluate the efficacy and safety of Gingko Ketone Ester Dropping Pills in treating angina pectoris and co-ronary heart disease. CNKI, Wanfang, SinoMed, PubMed, Cochrane Library and EMbase databases were retrieved on computer, and the randomized clinical trial(RCT) on Gingko Ketone Ester Dropping Pills in treating angina pectoris and coronary heart disease, which were published from the database establishment to December 31, 2019, were comprehensively collected. Literature screening, data extraction and quality evaluation were conducted independently by two researchers according to inclusion and exclusion criteria. Literature methodology quality evaluation was conducted with use of the Cochrane Handbook 5.3.0(bias risk assessment tool). Meta-analysis was performed with RevMan 5.3.0 software. A total of 10 RCTs were included. The results of the Meta-analysis showed that as compared with conventional Western medicine alone, the application of Gingko Ketone Ester Dropping Pills combined with conventional Western medicine treatment further improved the total effective rate and electrocardiogram effect(RR=1.43,95%CI[1.20,1.71],P<0.000 1). There were statistically significant differences in the number of angina attacks, the duration of angina and the amount of nitroglycerin used. In terms of safety indicators, four studies reported adverse reactions in the experimental group, including facial flu-shing, tachycardia, dizziness, dyspnea, nausea and other symptoms. Based on the existing findings, in the treatment of angina pectoris and coronary heart disease, Gingko Ketone Ester Dropping Pills combined with conventional Western medicine can improve the clinical total effective rate, electrocardiogram effect, number of angina attacks, duration of angina and the amount of nitroglycerin used. However, in the included studies, due to some methodological quality problems which would impact the reliability of literature results more high-quality randomized controlled trials are still needed for further verification.
