Comparison between coronary plaque 64-slice spiral CT characteristics and risk factors of coronary artery disease patients in Chinese Han population and Mongolian

ABSTRACT

To compare the coronary atherosclerotic plaque 64-slice spiral CT characteristics and the risk factors of Han [in Inner Mongolia] and Mongolian coronary artery disease patients. The plaques of 126 Mongolian and 269 Han patients were analyzed by 64-slice spiral CT coronary angiography. Their gender, age, height, body mass, the history of hypertension, diabetes, smoking and family diseases, the levels of triglycerides [TG], total cholesterol [TC], high density lipoprotein cholesterol [HDL-C] and low density lipoprotein cholesterol [LDL-C] were compared. The incidence of plaques [P < 0.05], the proportion of plaques in the circumflex branch [P < 0.05], the proportion of medium-severe lumen stenosis induced by plaques [P < 0.05], and the proportion of obstructive plaque involved multi-branch [P < 0.05] of the Mongolian patients were higher. The plaque compositions of the two groups did not differ significantly [P > 0.05]. The body mass index of the Mongolian patients was higher [P < 0.05]. The hypertension, diabetes, smoking history, TG, TC, HDL-C and LDL-C of the two groups did not differ significantly [P > 0.05]. The higher incidence of coronary atherosclerotic plaques and the more severe lesions of the Mongolian patients may be related to their higher body mass index
