Segmental Representation of Intimal Thickness in Ascending Aorta as Early Clinical Marker of Aging

Background: Intimal thickness is the innermost layer of aorta; play a vital role in development of atherosclerotic changes. It may vary in the different parts of the aorta and may increase with age. Methods: 120 aortas of adult human forensic bodies were taken. Histological slides were formed and the thickness of different segments of aorta were measured microscopically. Data were statically analyzed using ANOVA, p test methods. Results and Discussion: There is no significant difference of Intimal thickness in different segments of ascending aorta though it significantly increase with age may be due to accumulation of medial SMCs into intima. Results agree with previous workers. Conclusion: No significant difference between different segments of ascending aorta and it increase with age showing the aging aorta and early sign of atherosclerotic changes.
