To investigate whether there is a correlation of carotid intima-media thickness (IMT) and degree of sclerosis with coronary atherosclerotic heart disease (CAD).

Eighty patients with CAD were diagnosed by coronary angiography, at the same time, the carotid artery color Doppler ultrasound examination was performed to understand the degree of IMT and sclerosis, and then whether the degree of IMT and the degree of sclerosis were consistent with the severity of coronary artery was analyzed to determine the correlation.

For the patients with coronary heart disease, the more serious the coronary artery lesions was, the IMT was thicker, the occurrence rate of the plaque was higher. Carotid artery intima-media thickness, thickening, plaque thickness and incidence were significantly higher in patients with multivessel coronary artery disease than those with single vessel disease.

IMT and high-frequency ultrasound in carotid artery can indirectly reflect the situation of coronary atherosclerosis, combined with clinical characteristics, it can help to determine the severity of coronary artery disease, and provide indicators for early diagnosis of CAD.
