    BackgroundTo systematically evaluate the clinical efficacy of using the method of activating blood circulation and removing blood stasis in the treatment of microvascular angina (MVA) based on the meta-analysis method.MethodsA comprehensive search of randomized controlled trials on the treatment of MVA using the method of activating blood circulation and removing blood stasis in Chinese and English databases such as China National Knowledge Infrastructure Database, Wanfang Data Knowledge Service Platform, Vipshop Journal Resource Integration Service Platform, PubMed, Cochrane Library, Embase, Web of Science, and CBM was conducted, and the search time limit was from the establishment of each database to February 2023. All retrieved literature was screened, and data extracted according to the specified inclusion and exclusion criteria, and data analysis was completed using Revman 5.4 software.ResultsFifteen studies with a total of 1031 patients were finally included, and the results of the meta-analysis showed that the treatment with the method of activating blood circulation and removing blood stasis was more advantageous compared with the group of Western medicine alone. Among them, clinical effect of activating blood circulation and removing blood stasis (relative risk = 1.20, 95% confidence intervals [CI] [1.11, 1.31], P < .0001) and electrocardiographic efficacy (relative risk = 1.32, 95% CI [1.15, 1.51], P < .0001) were more effective, concentration levels of endothelin-1 (standardized mean difference = -2.14, 95% CI [-2.97, -1.31], P < .00001) and high sensitivity C-reactive protein (mean difference = -0.84, 95% CI [-0.93, -0.75], P < .00001) were lower, concentration levels of nitric oxide (standardized mean difference = 0.61, 95% CI [0.33, 0.89], P < .0001) was higher, and ST-segment depression range (mean difference = -0.07, 95% CI [-0.09, -0. 04], P < .00001) was smaller.ConclusionCompared with the treatment with Western medicine alone, the treatment of MVA is more effective by choosing the method of activating blood circulation and removing blood stasis.Copyright © 2024 the Author(s).
