Classification of Pressure Gradient of Human Common Carotid Artery and Ascending Aorta on the Basis of Age and Gender

TL;DR

This study uses computational fluid dynamics to analyze how pressure gradients in the carotid artery and ascending aorta vary with age and gender, aiming to assess cardiovascular disease risk factors.

Contribution

It introduces a CFD-based method to compare pressure gradients in arteries across different age groups and genders, highlighting age-related changes.

Findings

Pressure gradient decreases with age in both arteries.

Aorta pressure gradient is lower than carotid artery in all groups.

Gender differences in pressure gradients are observed.

Abstract

The current work is done to see which artery has more chance of having cardiovascular diseases by measuring value of pressure gradient in the common carotid artery (CCA) and ascending aorta according to age and gender. Pressure gradient is determined in the CCA and ascending aorta of presumed healthy volunteers, having age between 10 and 60 years. A real 2D model of both aorta and common carotid artery is constructed for different age groups using computational fluid dynamics (CFD). Pressure gradient of both the arteries are calculated and compared for different age groups and gender. It is found that with increase in diameter of common carotid artery and ascending aorta with advancing age pressure gradient decreases. The value of pressure gradient of aorta is found less than common carotid artery in both cases of age and gender.
