Abstract´╝Ü Objective To investigate carotid intima-media thickness and arterioles atherosclerosis in patients with prehypertension by using high-frequency ultrasound.Methods A total of 1162 healthy controls and 590 prehypertensive patients were enrolled in this investigation.High-frequency ultrasound was used to measure intima-media thickness and evaluate plaque score of the carotid artery.Results In comparison with the healthy controls,the incidence of carotid atherosclerotic plaque and the intima-media thickness of the prehypertensive patients were significantly increased.The detection rate of carotid atherosclerotic plaque was 45.3% in prehypertensive subjects.In addition,mild,moderate or calcified plaque was found in 68.9%,24.6% and 6.5% patients,respectively.Conclusion High frequency ultrasound could accurately evaluate intima-media thickness and atherosclerotic plaque of the carotid artery,which may be conductive to identify high-risk prehypertensive populations.
