Aim To know about the incidence rate of carotid atherosclerosis of the patients with coronary heart disease;To analyze the related risk factors of carotid atherosclerosis of the patients with coronary heart disease;To determine the relationship between the aggravation of carotid atherosclerosis and coronary atherosclerosis;To summarize the pathologic character of carotid atherosclerosis of the patients with various coronary heart disease.Methods Review the result of coronary angiography and carotid ultrasound and the related risk factors of the patients who were diagnosed as coronary heart disease through coronary angiography.The patients were divided into the carotidatherosclerosis group and the non-carotidatherosclerosis group.The patients were divided into stable angina pectoris(AP) group,unstable angina pectoris(UAP) group and acute myocardial infaction(AMI) group according to the diagnotic criterion of coronary heart disease of WHO.The patients were divided into group A(coronary artery of single vessel lession),group B(coronary artery of double vessel lession),group C(coronary artery of triple vessel lession) and group D(left main vessel lession).The aggravation of carotid atherosclerosis was graded.Results There were 198 patients with various aggravative carotid atherosclerosis among 228 patients with coronary heart disease(86.8%).Carotid atherosclerosis was much related with hypertension and non-related with age,sex,body mass index(BMI),smoking,drinking,hyperlipidermia,hyperuricermia and diabetes mellitus.The aggravation of carotid atherosclerosis got graver with the severity of coronary athero-sclerosis.But only the plaque number of group A was more than group D(P<0.05).The grading integral and Crouse integral of carotid atherosclerosis of AP group was not remarkablely less than UAP group.The grading integral of carotid atherosclerosis of AP group was less than AMI group and the Crouse integral of AP group was more.But there was no remarkable difference.The number of all plaque,and plaque of AP group was not remarkablely less than UAP group and AMI group.The plaque of all the three groups had no obvious difference.There was the plaque among the three groups.Conclusion Carotid atherosclerosis is relative to coronary heart disease.
