Study On The Correlation Between Carotid Artery Ultrasonography And Coronary Artery Severity In Patients With Coronary Heart Disease

Objective In order to improve the efficiency of carotid ultrasound examination,the relationship between carotid ultrasound examination and severity of coronary artery disease was analyzed.The risk of coronary heart disease was evaluated.virus,anti-bacteriostasisMethods Coronary angiography and carotid ultrasound were performed in 415 inpatients.According to the results of angiography,the patients were divided into coronary heart disease group(305 cases)and normal coronary angiography group(110 cases).Coronary artery disease group was divided into single vessel group(182 cases),double vessel group(85 cases)and three vessel group(38 cases).All patients were examined by carotid ultrasound,the IMT value of bilateral carotid artery was detected,the number of carotid plaques was counted,the crouse score of carotid plaques was calculated,the total area of plaques and the proportion of unstable plaques were calculated.Make statistical credit analysis on all relevant results.Results The MIT value,the number of carotid plaques,the crouse score of carotid plaques,the total area of carotid plaques and the proportion of unstable carotid plaques were higher in the single vessel group,double branch group and three branch group than in the normal coronary angiography group.However,there was no significant difference in MIT value and carotid plaque number between single vessel group,double vessel group and three branch group.The crouse scores of carotid plaques in the two and three branches groups were higher than those in the single branch group,but there was no statistical difference between the two and three branches groups.The total area of carotid plaques and the proportion of unstable carotid plaques in the two and three branches groups were higher than those in the single branch group,and the total carotid plaque surface in the three branches group was higher than that in the single branch group.The proportion of unstable plaques in carotid artery was higher than that in double vessel group,which was increased with the increase of the number of coronary artery diseased branches.Conclusion Carotid plaque had a significant correlation with coronary heart disease.The IMT value of carotid artery,the number of carotid plaques,the score of carotid plaque,the total area of carotid plaque and the proportion of unstable plaque were significant in distinguishing coronary artery disease from non-coronary artery disease.However,the MIT value and the number of carotid plaques were not related to the number of coronary artery lesion branches.The crouse score of carotid plaque increased from single to double coronary artery,the total area of carotid plaque and the proportion of unstable plaque increased with the increase of coronary artery branches.
