Pulsed Doppler Evaluation of Diameter, Blood Velocity and Blood Flow of Common Carotid Artery in Sustained Essential Hypertension
Why the study?
Does sustained essential hypertension alter the diameter, blood velocity, and blood flow of the common carotid artery compared to normotensive subjects?

Implication
Reduced carotid flow in older hypertensives merits prospective validation; leaves open whether wall modifications drive cerebrovascular risk.
Structured PICO
Does sustained essential hypertension alter the diameter, blood velocity, and blood flow of the common carotid artery compared to normotensive subjects?
P
Population
38 patients with sustained essential hypertension and 38 age-matched normal subjects, classified into those younger and older than 45 years (total n=76).
I
Intervention
Pulsed Doppler velocimeter evaluation of the common carotid artery
C
Comparator
Age-matched normal subjects
O
Outcome
Diameter, blood flow velocity, and volumic flow of the common carotid arterysurrogate
Sustained essential hypertension in patients over 45 years is associated with reduced blood flow velocity and volumic flow in the common carotid artery without changes in arterial diameter, suggesting structural or functional wall modifications.
