  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.
