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 Aims 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 ( 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 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.
