Aim To investigate the consistency of carotid intima-media thickness （IMT） and carotid atherosclerosis plaque and coronary heart disease,to provide a method and basis for clinical early diagnosis and treatment of coronary heart disease. Methods 179 suspected coronary heart disease patients underwent coronary angiography （CAG） and carotid ultrasound to measure carotid IMT and calculate the plaque score. Patients were divided into coronary heart disease group and non-coronary heart disease group by imaging results. The relationship between carotid IMT and carotid atherosclerosis plaque and coronary heart disease weres analyzed. Results Coronary heart disease group had 114 cases,non-coronary heart disease group had 65 cases,the carotid IMT of patients in the two groups were 1.08±0.48 mm and 0.85±0.20 mm respectively,the plaque scores of patients in the two groups were 1.61±1.02 and 1.07±0.43,and the incidence of carotid artery plaque was 79.83% （91/114） and 21.54% （14/65）,the differences were statstically significant （P<0.01）. Conclusion Carotid IMT or carotid atherosclerosis plaque are highly related with coronary heart disease,which can be used as screening for coronary heart disease.
