Objectives:The peripheral atherosclerosis(AS) of carotid artery（CA）, femoral artery（FA）, common iliac artery（CIA）and aortic arch（AA） were observed by ultrasonography and chest X-ray respectively to evaluate their relationship with coronary heart disease (CHD).Methods: 74 cases ndergoing coronary angiography(CAG) were checked by Color ultrasonography and chest X-ray respectively to observe the case of arteriosclerosis of CA, FA,CIA and AA.The correlation between the factors, including the artery IMT , AS plaque and calcification，and the results of CAG were analyszed.Results:①Aortic arch calcification(AAC) increased the risk of CHD significantly.②The number of stenosed coronary artery incraesed with the risks of IMT of CA, FA or CIA.③Atheromatous plaque and semi-quantitative plaques classification is an effective way to diagnose CHD.④Chest X-ray film could detecting AAC, and high frequency ultrasound is an effective tool to detect the peripheral AS.Conclusions：AAC and IMT，atheromatous plaque and semi-quantitative plaques classification of the peripheral arterial are effective indicators for the diagnosis of CHD, Chest X-ray film and peripheral artery ultra-sonography are good methods for the diagnosis of CHD,meanwhile they are an effective tool for census and screening of the CHD.
