THE STUDY ON THE RELATIONSHIP BETWEEN CAROTID ATHEROSCLEROSIS AND CORONARY ATHEROSCLEROSIS

Objective: To define the relationship between carotid atherosclerosis (CAS) and coronary arterial atherosclerosis (CAAS) by measurement of carotid IMT and plaques. Methods: Coronary arteriography was performed in 47 patients to judge the degree of CAAS. The carotid IMT and plaques were measured by ultrasound. Results: (1)There was significant difference between CAAS group and normal group in IMT, carotid plagues score and incidence of carotid atherosclerosis plaques (P0 001,P0 001,P0 005). There was significant difference between 2\|3 rami of CAAS group and single ramus group in carotid plaques score (P0 05). There was no difference between 2\|3 rami of CAAS group and single ramus group in IMT and incidence of carotid plaques score. (2)There was positive correlation between coronary arteriography score and IMT, carotid atherosclerosis score (r=0 65,0 63,P0 01). There was positive correlation between rami of CAAS and IMT, carotid atherosclerosis plaques score (r=0 68,0 61,P0 01). Conclusion: CAS is a window of atherosclerosis. There is close relationship between CAS and CAAS.\;
