The Efficacy and Safety of Compound Danshen Dripping Pill Combined with Percutaneous Coronary Intervention for Coronary Heart Disease

Abstract

Objective. Compound Danshen dripping pill (CDDP) is a well-known Chinese patent medicine, which is commonly used for the treatment of coronary heart disease (CHD) in China. This study is aimed at systematically assessing the clinical efficacy of CDDP for CHD patients. Methods. Eight databases were retrieved for eligible research studies from the founding date to April 20, 2020. Risk ratio (RR) was used to assess major adverse cardiac events (MACE) and adverse reactions, and mean difference (MD) was adopted to evaluate the hemorheology and blood lipid indexes, vascular endothelial function, cardiac function, and inflammation. Result. Twenty randomized controlled trials involving 2574 participants with CHD were included. The results indicated that, compared with percutaneous coronary intervention (PCI) alone, the combination of CDDP with PCI treatment remarkably reduced MACE (RR = 0.53, 95% confidence interval (CI) (0.44, 0.65), $P<0.00001$ ). Moreover, hemorheology and blood lipid parameters and inflammatory mediators of CHD patients were also dramatically mitigated after the combined therapy $\left(P<0.01\right)$ . In addition, vascular endothelial function and cardiac function were prominently improved by this combination $\left(P<0.001\right)$ . However, there was no significant difference in adverse reactions between the two groups $\left(P>0.05\right)$ . Conclusion. Evidence from the meta-analysis demonstrated that CDDP combined with PCI treatment prominently reduced the incidence of MACE, improved cardiovascular functions, and inhibited inflammation in CHD patients. Therefore, CDDP combined with PCI treatment could be an effective and safe therapeutic method for CHD patients.
