Effect of Traditional Chinese Medicine combined with Western Medicine on blood lipid levels and inflammatory factors in patients with angina pectoris in coronary heart disease identified as intermingled phlegm and blood stasis syndrome: a network Meta-analysis.

To evaluate the clinical efficacy of Traditional Chinese Medicine prescriptions for resolving phlegm in the treatment of angina pectoris of phlegm-stasis coronary heart disease by a network Meta-analysis.Randomized controlled trials (RCTs) on clinical efficacy of CHD angina pectoris with interaction of phlegm and blood stasis were searched in PubMed, Springer, the Cochrane Library and Chinese-language databases China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data from their inception to December 2021. Literature was screened and literature bias risk was assessed by RevMan5.4 software. The overall response rate, the duration of angina attack, the levels of serum lipids such as total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C), and expression of hypersensitive C-reactive protein (hs-CRP) were selected as outcome indicators for network Meta-analysis and mapped using Stata15.1 software.Totally, 26 RCTs were included, involving 2098 participants. There were 6 TCM formulas with the effects of dispelling phlegm and removing blood stasis. Taking conventional Western Medicine as the common intervention measures, the results showed that the overall response improvement rate from high to low was displayed as modified Xiaoxianxiong decoction (, MXD), Danlou tablet (, DT), modified Gualou Xiebai Banxia decoction (, MGXBD), modified Wendan decoction (, MWD), modified Zhishi Xiebai Guizhi decoction (, MZXGD), and modified Erchen decoction (, MED). The sequence of angina attack duration improvement from high to low was MZXGD, MGXBD, DT, MWD, MXD. The sequence of TC improvement from high to low was MZXGD, MED, DT, and MGXBD. Sequence of improving TG from high to low was MED, MZXGD, MGXBD, and DT. For LDL-C improvement, the effect from good to poor was MZXGD, MGXBD, DT, and MED. With regard to HDL-C improvement, the effect was ranked as MED, MZXGD, MGXBD, and DT from good to poor. hs-CRP expression from high to low was MZXGD, MXD, MED, MWD, and MGXBD.TCM formula with the effects of dispelling phlegm and removing blood stasis combined with conventional Western Medicine has obvious advantages in treating CHD angina pectoris with interaction of phlegm and blood stasis. MZXGD has great potential in increasing the overall response rate, reducing Duration of angina attack improving blood lipids, and reducing inflammatory factors. However, due to the limitations of extant studies, the conclusions of this study need to be confirmed by numerous reasonably-designed RCTs.
