    ¡¾Abstract¡¿ AIM: To assess the prevalence and risk factors for coronary artery calcification (CAC) by electron beam tomography (EBT) in adults with established type 2 diabetes. METHODS: A total of 94 subjects aged 36-78 years underwent cardiac EBT with CAC incidence and calcium scoring. Laboratory evaluations of 75 g oral glucose tolerance test (OGTT), HbA1c, triglyceride, total cholesterol were performed. The correlation of score with age and other clinical evidence was analyzed. RESULTS: The incidence of CAC in impaired glucose tolerance (IGT) (93.3%), Diabetes (96.4%) and coronary artery disease (CHD) (90.9%) groups was significantly (P<0.01) higher than that in normal controls. The score of CAC in IGT, diabetes and CHD groups, though with statistical significance, was also higher. CAC was found to be correlated with age (r=0.423, P<0.01). CONCLUSION: Our data suggest a prevalence of CAC in those with type 2 diabetes. But the score of CAC should be used together with other parameters of EBT in diagnosing CAD. ......
