Abstract

Background: Despite previously shown relationship between the aortic Atherosclerosis and Coronary Artery disease, the relationship between Aortic distensibility and the presence, extent, and composition of thoracic aortic plaques (TAP) is not widely assessed. In the current study, we evaluated the relationship between Aortic distensibility and the presence, extent, and composition of TAP. Materials and Methods: Descriptive ECG-gated coronary multi-slice CT was performed on 150 participants (75 with and 75 without TAP; mean age: 59. 0 ± 13. 5 years; 54. 7% female) using two 64-slice and a dualsource 256-slice scanners. Aortic distensibility index (ADI) was measured at local TAP (L-ADI) and predefined locations including ascending Aorta (A-ADI), proximal (PD-ADI), and distal descending Aorta (DD-ADI). Total ADI (T-ADI) was the mean of predefined locations. Pearson’ s and Spearman’ s correlation tests and multivariate logistic regression were used to examine the association between study meas ures. Results: All ADIs of the patients with calcified TAP were significantly lower than those with non-calcified or without TAP (p<0. 0001). All ADIs, except for L-ADI, of the patients with coronary plaque were significantly lower than those without coronary plaque (p<0. 0001). In the multivariate analysis adjusted for age, gender, diabetes mellitus, hypercholesterolemia, hypertension, and cigarette smoking, presence of TAP, particularly calcified TAP, was independently correlated with ADI. Conclusion: A less distensible thoracic Aorta is associated with calcified aortic and coronary plaques. Aortic plaque is an independent predictor of the stiffer Aorta.
