The Correlation Study of Carotid Arteries Itima-media Thickness and Carotid Arteries Plaque in Hypertension Complicating Acute Cerebral Accident

Objective To study the carotid arteries itima-media thickness(IMT) and carotid arteries plaque in patients with hypertension complicating acute cerebral accident,and to explore the correlation study of carotid arteries itima-media thickness and carotid arteries plaque in hypertension complicating acute cerebral accident.Methods To measure the carotid arteries IMT and carotid arteries plaque including IMT,plaque size and position and the lumina diameter of carotid arteries in 120 patients with hypertension and 10 normal subjects by using color doppler high frequency ultrasound.Result The carotid arteries itima-media thickness was thickened significantly in all patients,the arteries itima-media thickness in 112 case were significantly thickened(93.3%;),there were165 carotid arteries plaque in 89 cases,included 58 hard plaque and 109 soft plaque 42 cases had carotid arteries stenosis,included slight stenosis in 25 cases,midrange stenosis in 12 and severe stenosis in 5 cases,the arteries itima-media thickness in shock group were significantly thickened than that in simple hypertension group,IMT 1.0mm and over 2 carotid arteries plaque and over 1 hard plaque can be used to predict acute cerebral accident with higher sensitivity 85%,specificity 86%,and postive predictive value 83%.Conclusion Color doppler high-frequency ultrasound can be used to measure the carotid arteries itima-media thickness and the carotid arteries plaque in patients with hypertension.It offer value information to predicting the hypertension complicating acute cerebral accident.
