    The aorta naturally increases in size with age, independent of atherosclerosis or hypertension. This age-related aortic enlargement warrants further study for forensic age determination.

    Area of Science:

    • Gerontology
    • Cardiovascular Science
    • Forensic Pathology

    Background:

    • Aortic size increases with advancing years, a phenomenon previously noted but under-researched.
    • Aortic calcification is linked to atherosclerosis, with prevalence varying by sex and location.

    Purpose of the Study:

    • To investigate the relationship between aging and aortic dimensions.
    • To explore the potential of aortic size measurement in forensic age estimation.
    • To analyze factors associated with aortic calcification.

    Main Methods:

    • Post-mortem measurements of aortic length and circumference in 336 specimens.
    • Assessment of aortic calcification and its correlation with various health conditions.

    Main Results:

    Related Experiment Videos

    • Aortic size progressively increases with age, unrelated to atherosclerosis or hypertension, suggesting a true aging process.
    • Aortic calcification prevalence and severity correlate with atherosclerotic plaque severity, occurring earlier and more severely in men and in the abdominal aorta.
    • No association found between aortic calcification and hypertension, diabetes, or neoplasia.

    Conclusions:

    • Aortic enlargement is a natural part of aging and may be a useful indicator for forensic age determination.
    • Aortic calcification patterns align with established atherosclerosis progression, with distinct demographic and vascular disease associations.
    • Hypertension, diabetes, and neoplasia are not directly associated with the degree of aortic calcification.
