The correlation analysis between the clinical indexes and the microbiota. (a) The correlation analysis between clinical indexes and bacterial microbiota at the genus level. (b) The correlation analysis between clinical indexes and bacterial microbiota at the species level. (c) The correlation analysis between the severity of CHD and bacterial microbiota at the genus level. (d) The correlation analysis between the severity of CHD and bacterial microbiota at the species level. “Process” stands for the time from the initial diagnosis of CHD to this day. The Spearman’s correlation analysis was performed and R 3.5.1 software with pheatmap package was use for visualization. The scale bar in heatmaps stands for the correlation coefficient in the Spearman’s correlation analysis. *p < 0.05; **p < 0.01. NCA, Narrowed coronary artery. 71 samples were used in each analysis
