    Measurements of the aortic knob in 691 patients reveal a link between aortic width and age. However, aortic width did not correlate with hypertension severity but was larger in arteriosclerotic and hypertensive individuals.

    Area of Science:

    • Cardiovascular imaging
    • Radiology
    • Gerontology

    Background:

    • The aortic knob's dimensions can be influenced by various physiological and pathological factors.
    • Age and cardiovascular conditions like arteriosclerosis and hypertension are suspected to affect aortic width.

    Purpose of the Study:

    • To investigate the relationship between aortic knob width and age.
    • To determine if aortic knob width correlates with the degree of hypertension.
    • To compare aortic knob width across normal, arteriosclerotic, and hypertensive patient groups.

    Main Methods:

    • Retrospective review of chest roentgenograms from 691 patients.
    • Measurement of the aortic knob width.
    • Statistical analysis to assess correlations and group differences.

    Main Results:

    • A significant positive correlation was observed between aortic knob width and patient age.
    • No significant correlation was found between aortic knob width and the degree of hypertension.
    • Average aortic knob width was significantly increased in patients with arteriosclerosis and hypertension compared to normal subjects.

    Conclusions:

    • Aortic knob width is a reliable indicator of aging.
    • While not directly correlated with hypertension severity, increased aortic knob width suggests underlying arteriosclerotic and hypertensive changes.
    • Chest roentgenography provides valuable data for assessing aortic dimensions in relation to cardiovascular health.
