目的探讨双源CT 定量评价糖尿病合并冠心病的诊断价值.方法应用双源CT对糖尿病合并冠心病(DN)50例和非糖尿病合并冠心病(非DN)50例,对两组发病率、斑块组成、CTA 基本特征进行比较.结果 DM患者冠心病发病率91%,明显高于非DM 患者的冠心病发病率73%(χ2=3.784,P<0.05)；两组斑块组成不存在统计学差异(P>0.05)；DM 组阻塞性冠心病26.0%,明显高于非 DM 组6.0%(χ2=4.56, P =0.001)；DM 组单支病变、双支病变、三支病变分别为20.0%、12.0%、10.0,明显高于非 DM 组非 DM 组6.0%、4.0%、2.0(χ2=4.156,χ2=4.045,χ2=4.254,P=0.003,P =0.004,P =0.005)；DSCT的灵敏度为85.6%,特异度为90.9%,阳性预测值为88.5%,阴性预测值为88.5%,诊断的符合率为88.5%,DSCT 和 CAG 对每支冠脉狭窄的检差异无统计学意义(χ2=1.737,P=0.187).结论双源CT 是一种评价糖尿病性冠心病的可行的方法；糖尿病性冠心病病变复杂,累及血管范围广且严重.

Objective To investigate the diagnostic value of dual source computed tomography(DSCT) in diabetic patients with coronary artery disease.Methods Application DSCT in diabetic patients with coronary heart disease (DN) of 50 cases and 50 cases of non-diabetic patients with coronary heart disease (non -DN)of the two groups, compare with incidence、plaque 、and to compare the basic characteristics of the CTA. Results incidences of 91% in DM group were significantly higher than 73% in non-DM group(χ2= 3.784, P<0.05);The plaque composition in two groups were not exist significant difference(P >0.05);The obstructive coronary heart disease 26.0% in DM group were significantly higher than 6.0% in the non-DM group(χ2=4.56, P=0.001); The single vessel disease, double vessel disease and three lesions 20.0%, 12.0 %, 10.0 were significantly higher than 6.0%, 4.0%,2.0 in non-DM group (χ2=4.156, χ2=4.045,χ2=4.254,P=0.003,P=0.004,P=0.005);THE sensitivity、specificity、positive predictive value were 85.6%、90.9%、88.5% respective in DSCT; DSCT and CAG each coronary stenosis difference were not statistically significant(χ2=1.737, P=0.187).Conclusion Dual source CT is a feasible way in evaluation of diabetic coronary heart disease; diabetic coronary heart disease is complex, involving a wide range of serious vascular.
