Abstract Objective To investigate the effect of hypertension on ascending aorta, aortic root and the formation of coronary artery plaques. Methods Clinical data of 200 patients who received CTA examination due to suspected coronary heart disease in Nantong Hospital of Traditional Chinese Medicine, Jiangsu Province from May 2014 to May 2019 were retrospectively analyzed. They were divided into hypertensive group (150 cases) and non-hypertensive group (50 cases) according to whether they had hypertension or not. All patients underwent coronary artery CTA examination. The aortic root and internal diameter of ascending aorta, the incidence of coronary plaques, the stenosis degree of the involved segments, the condition and incidence of coronary artery disease were observed and compared in the two groups. Results Internal diameter of ascending aorta in hypertensive group was larger than that in non-hypertensive group (P < 0.05). There were no significant differences in the long diameter, short diameter of middle aortic valve ring, the internal diameter at sinus canal junction and the maximum internal diameter of Warwick sinus between the two groups (P > 0.05). The incidence of coronary plaques in the hypertension group was higher than that in the non-hypertension group, and the difference was statistically significant (P < 0.05). There was no significant difference in the degree of coronary artery stenosis between the two groups (P < 0.05). There was statistical significance in the comparison of the condition and incidence of coronary artery disease between the two groups (all P < 0.05). Conclusion Hypertension can cause the internal diameter of ascending aorta to dilate and promote the formation of coronary plaque.
