Objective To study correlation of ascending aorta elastic and CT imaging features in patients with coronary heart disease. Methods 126 cases patients with CHD were selected as the research object, all patients were given DSCT coronary angiography examination, according to the presence of coronary artery stenosis were divided into coronary stenosis group and no coronary stenosis group, according to the extent of coronary stenosis were divided into mild stenosis, moderate stenosis group, severe stenosis group; ascending aorta elastic parameters and the Gensini score were compared between different groups. Results 1 Coronary stenosis group % Ao, AoD, AoC were was significantly than that no stenosis group, AoSI, the Gensini score were significantly higher than no stenosis group (t=6.849-34.201, P<0.05, P<0.01); 2 Mild group % Ao, AoD, AoC were significantly higher than that of moderate group, severe group, AoSI, Gensini score were significantly lower than the moderate group and severe group, moderate group % Ao, AoD, AoC were significantly higher than that of severe group, AoSI, Gensini were significantly lower than the severe group (t=3.456-17.542, P<0.05,P<0.01); 3 Gensini score and AoSI significant positive correlation（r=0.722, P<0.001), and % Ao, AoD significant negative correlation (r=-0.432, 0.261, P<0.001). Conclusion Ascending aorta elastic and coronary artery stenosis degree have good correlation, regular detection ascending aorta elastic function help to early intervention and treatment in patients with subclinical state
