ABSTRACT

Background: Tobacco use is mainly classified into two forms, smokeless and smoking. In India, smoking is mainly in the form of bidis and cigarettes. Smoking leads to serious health effects like arterial stiffness and aortic aneurysms. Aim: The purpose of this study was to determine the relationship between smoking and aortic diameter among smokers and non-smokers. Methods: A case-control study was conducted including 34 smokers and 34 non-smokers. Participants who were referred for contrast-enhanced computed tomography (CECT) thorax were included. The diameters of ascending aorta, proximal and distal arch of aorta and descending aorta were measured in the arterial phase using distance measuring tools. Results: In smokers, the mean diameter of ascending aorta, proximal and distal arch of the aorta and descending aorta were 30.51 ± 2.96, 25.38 ± 3.20, 22.70 ± 2.33 and 23.28 ± 2.02, respectively. In non-smokers, the mean diameters of ascending aorta, proximal and distal arch of the aorta and descending aorta were 31.32 ± 4.54, 25.42 ± 3.10, 22.77 ± 3.41 and 23.54 ± 3.25 respectively. Conclusion: According to the current study, there was no significant difference between smoking and aortic diameter among smokers and non-smokers. The duration of smoking has no effect on ascending aorta, proximal and distal arch of aorta and descending aorta.
