Quality assessment was conducted using the Cochrane Collaboration's tool. Heterogeneity was tested using the Chi-squared-based Q statistic test and I2 statistic.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The study included a total of 15 articles, with 1204 patients in the cohort, divided into 625 cases in the observation group and 579 cases in the control group. Compared to Western medicine alone, the combination of Shixiao powder and Western medicine significantly improved the effective rate in treating angina pectoris of coronary heart disease [RR\u2009=\u20091.25, 95%Cl (1.18\u20131.32),\n P<\/jats:italic>\n \u2009&lt;\u20090.00001]. The improvement in ECG ST segment was superior [RR\u2009=\u20091.32, 95%Cl (1.21\u20131.43),\n P<\/jats:italic>\n \u2009&lt;\u20090.00001]. Additionally, there was a decrease in serum CRP level [WMD=\u22120.8, 95%Cl (-1.43\u20130.18), Z\u2009=\u20092.52,\n P<\/jats:italic>\n \u2009=\u20090.012\u2009&lt;\u20090.05]. The assessment of publication bias concluded that there was no publication bias, suggesting that the conclusions of this study are accurate and reliable.\n <\/jats:p>\n <\/jats:sec>\n \n
