Title: The value of carotid artery ultrasonic examination for predictiong coronary heart disease.
Abstract: Objective To predict coronary atherosclerosis by carotid artery ultrasonic examination,and to find more ideal ultrasonic signs for the prediction of atherosclerosis.Method Using ultrasound to observe the carotid artery of the patients with clinical definite coronary heart disease,and compare with the coronary artery angiography (CAG) of partial patients.Observing items included the internal diameter of artery,internal and middle membrane thickness(IMT),amounts of plaque and calcification,velocity of blood stream,pulsation index(PI),and resistant index(RI) of left and right common carotid arteries(CCA).Calculated the cross-sectional area of the internal and middle membrane of the common carotid artery(IMCSA).Results It showed that the internal diameter of CCA augmented,IMT became thicker,IMCSA became larger,the velocity of blood stream became slower,PI and RI increased.This results also showed that the rate of plaque formation was the highest in the group with angina pectoris and higher in the group with hypertension and myocardial infarction.Conclusions The increase of the IMT at the cross of common carotid arteries,the rough changes of the internal and middle membrane,and the strong resonance are the early manifestations of atherosclerosis.
