title: Increased detection of coronary atherosclerosis on 320-slice computed tomographic angiography with burden of cardiovascular risk factors and complications in patients with type 2 diabetes.
abstract: OBJECTIVE
  The cardiovascular risk factors and diabetic complications are related to coronary atherosclerosis. However, the evaluation of the prevalence of coronary atherosclerosis based on their accumulation remains to be determined.
  
  
  METHODS
  247 consecutive Chinese subjects with type 2 diabetes but without history of coronary heart disease (CHD) underwent 320-slice computed tomographic coronary angiography, including no coronary atherosclerosis, non-obstructive atherosclerosis (<50% stenosis) and obstructive atherosclerosis (≥50% stenosis). Conventional cardiovascular risk factors, albuminuria, renal dysfunction and diabetic retinopathy (DR) were determined. Framingham Risk Score (FRS) was used to assess the 10-year CHD risk.
  
  
  RESULTS
  Increase in burden of cardiovascular risk factors and diabetic complications were significantly associated with the likelihood of being a higher coronary atherosclerosis category. In the analysis for trend through the categories of burden score or FRS stratification, the percentage of obstructive atherosclerosis was increased and the percentage of no atherosclerosis decreased as the burden score and FRS increased (all p<0.005), respectively. The areas under the receiver operator curve for the burden score versus FRS were greater at predicting coronary atherosclerosis and obstructive atherosclerosis (p=0.004 and p=0.002), respectively.
  
  
  CONCLUSIONS
  The prevalence of coronary atherosclerosis was increased with the accumulation of cardiovascular risk factors and diabetic complications. The burden of these clinical and biochemical risk factors has increased ability for prediction of the presence and severity of coronary atherosclerosis over FRS in type 2 diabetic patients.
