Objective To make use of coronary CTA to determine the incidence rate of coronary atherosclerosis for non-diabetic asymptomatic people who have risk factors and evaluate its correlation with risk factors. Methods We recruited non-diabetic asymptomatic people who had high-risk factors (sex, age, hypertension, hyperlipidaemia) and divided them into single high-risk factor group and multiple high-risk factors group. Statistics was conducted on the incidence rate of disease for people who had high-risk factors in coronary atherosclerosis. Results Single risk factor grouping analysis showed that gender and age had significant difference in the incidence of CA(χ2＝4.6,P＝0.0032,χ2＝6.5,P＝0.0108) . For risk factors between groups, the incidence of multiple risk factors CA had significant difference (χ2＝4.6,P＝0.0032,χ2＝6.5,P＝0.0108). Logistic regression analysis showed that risk factors correlated with age and incidence of CA (OR＝1.77, CI＝1.19-2.66). Conclusions In asymptomatic non-diabetic population, CTA provides important information about coronary plaque in one scan, gender and age may have a greater risk of CA disease. As a non - invasive examination, CTA plays an important role in the diagnosis of CA.
