RESUMEN
This paper was aimed to study the effectiveness and safety of TanshinoneⅡA Sulfonate Sodium Injection in the treatment of unstable angina pectoris (UAP). Keywords such as coronary atherosclerotic heart disease, coronary heart disease, unstable angina, chest impediment, cardialgia, TanshinoneⅡA Sulfonate Sodium Injection, tanshinone injection, tanshinoneⅡA sulfonate, unstable, angina, randomized controlled trial (RCT), and clinical trials were searched in CNKI, VIP, Wanfang and Pubmed from the construction of database until October 31st, 2014. The inclusion criteria were RCT with clinical data integrity, similar literature research methods, and good balance between groups. The Jadad score method was used to carry out quality assessment. Meta-analysis was conducted by RevMan5.2 software. Count data was processed by odds ratio (OR). Measurement data was processed with the weighted mean differences (WMD). The 95% confidence interval (CI) was also calculated. The heterogeneity test result of included literatures was P > 0.05. The fixed effects model was used in the meta-analysis. On the other hand, random effect model was used. For the analysis results of more than 10 papers, the funnel plot was used in the analysis of publication bias. The results showed that a total of 34 studies were included. The results of meta-analysis suggested that the total efficiency of conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP was [OR = 3.83, 95%CI (3.11, 4.71),P < 0.000 01]. The electrocardiogram improvement rate was [OR = 3.34, 95%CI (2.61,4.28),P < 0.000 01]; plasma viscosity improvement was [WMD = -0.20, 95%CI (-0.38, -0.03),P = 0.03]; high shear viscosity of whole blood improvement was [WMD = -0.67, 95%CI (-0.85, -0.50),P < 0.000 01]; C-reactive protein improvement was [WMD = -2.66, 95%CI (-3.31, -2.00),P < 0.000 01]. It was concluded that the conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP had certain clinical effect with no obvious adverse reaction. However, due to the poor quality of the existing research literatures, the results should be further verified by large amount of high quality RCTs.
