Objective To discuss the relation of carotid wall intima-media thickness in the patients with cardiovascular events. Methods 46 cases of patients with cardiovascular events were confirmed by way of coronarography, whose coronary arteriostenosis≥70%, In the control group of 40 cases with coronarography whose coronary artery are normal. All are explored by color poppler ultrasonoscope to be measured for Carotid wall intima-media thickness. Results The patients in group coronary artery disease have significantly increased IMT. Conclusion Adding Carotid wall intima-media thickness can predict cardiovascular events.
