[Aortometric correlations in normal and pathological subjects]
Insights
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.
Abstract:
The chest roentgenograms of 691 normal, arteriosclerotic and hypertensive patients have been reviewed for measurements of the aortic knob. There is a significant correlation between the width of the aorta and age, but no such correlation was found with the degree of hypertension. The comparison between average widths of the aorta in the 3 categories of subjects has shown its increase in arteriosclerotic and hypertensive patients.
