Network Meta-analysis of traditional Chinese medicine injections in treatment of chronic pulmonary heart disease

Abstract

Based on the network Meta-analysis, the efficacy and safety of different traditional Chinese medicine(TCM) injections in the treatment of chronic pulmonary heart disease(CPHD) were systematically evaluated. CNKI, Wanfang, VIP, SinoMed, Web of Science, PubMed, EMbase, and Cochrane Library were searched to collect randomized controlled trial(RCT) of TCM injection in the treatment of CPHD from inception to October 1, 2023. The quality of the included studies was evaluated by the bias risk assessment tool recommended by the Cochrane systematic evaluation manual version 5.3. Stata 17.0 and RevMan 5.4 software were used for statistical analysis of the data. Finally, 103 RCTs were included, involving 9 332 patients and 13 kinds of TCM injections. Network Meta-analysis yielded the following results.(1)In terms of improving the total clinical effective rate, the top three intervention measures in SUCRA ranking are Shuxuetong Injection + conventional western medicine>Ligustrazine Injection + conventional western medicine>Xinmailong Injection + conventional western medicine.(2)In terms of reducing pulmonary artery pressure, the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Ligustrazine Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(3)In terms of improving left ventricular ejection fraction(LVEF), the top three intervention measures in SUCRA ranking are Xinmailong Injection + conventional western medicine>Danhong Injection + conventional western medicine>Ginkgo Damo Injection + conventional western medicine.(4) In terms of reducing brain natriuretic peptide(BNP), the top three intervention measures in SUCRA ranking are Xinmailong Injection + conventional wes-tern medicine>Ginkgo Damo Injection + conventional western medicine>Danhong Injection + conventional western medicine.(5) In terms of increasing arterial oxygen partial pressure(PaO_2) and reducing arterial carbon dioxide partial pressure(PaCO_2), the top three intervention measures in SUCRA ranking are Shenxiong Glucose Injection + conventional western medicine>Shenmai Injection + conventional western medicine>Shenfu Injection + conventional western medicine.(6) In terms of improving arterial oxygen saturation(SaO_2), the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Xinmailong Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(7) In terms of increasing the percentage of forced expiratory volume in the first second(FEV_1%), the top three intervention measures in SUCRA ranking are Shenfu Injection + conventional western medicine>Tanshinone Sodium Ⅱ_A Sulfonate Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(8) In terms of increasing the proportion of forced expiratory volume to forced vital capacity in the first second(FEV_1/FVC), the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Shuxuetong Injection + conventional western medicine>Danhong Injection + conventional western medicine.(9) In terms of safety, neither the experimental group nor the control group experienced any serious adverse drug reactions during the treatment period. In summary, combining TCM injection with conventional western medicine treatment can improve the comprehensive efficacy of treating CPHD, reduce pulmonary artery pressure, and improve cardiopulmonary function and arterial blood gas levels. However, due to the limitations of the quality and quantity of research methodology included, the above conclusions need to be further validated by more well-designed and high-quality RCT.
