摘　　要：目的:评价常规心电图及64层双源螺旋CT冠状动脉成像(DSCT)对2型糖尿病(T2DM)合并冠心病的诊断价值。方法:2009年1月～2012年1月收治T2DM疑似合并冠心病患者,对其进行常规心电图(ECG)、DSCT及选择性冠脉造影(CAG)检查。结果:以CAG为金标准,54例患者明确诊断为冠心病53例。ECG对T2DM合并冠心病的诊断敏感性为54.4%,符合率为55.6%,DSCT诊断敏感性100%,符合率98.1%。两组比较具差异有显著性(P<0.05)。以各支冠脉为基础,DSCT诊断冠脉明显狭窄的灵敏度、特异度、阳性预测值、阴性预测值、符合率分别为88.6%、88.29%、87.7%、72.7%、88.4%。结论:DSCT是诊断T2DM合并冠心病较为可靠、安全、简便的无创检查方法,对在糖尿病患者中筛选及诊断冠心病具有极大价值。Objective： To study the role of ECG and DSCT in diagnosis of patients with diabetes and coronary heart disease. Meth- ods： ECG, double source spiral computed tomography （DSCT） and Coronary angiogra- phy （CAG） were tested respectively in 54 inpatients of our hospital in between Ja- nuray2009 and Januray 2012. Results： 53 patients of 54 patients were confirmed the diagnosis of coronary heart disease by CAG. ECG had a sensitive rate of 54.4% and cor- responding rate of 55.6%. DSCT had a sen- sitive rate of 100% and corresponding rate of 98. 1%. There were significant differ- ences between the two groups in ECG and DSCT. DSCT test sensitivity, specificity, pos- itive predictive value and negative predictive value was88. 6%, 88. 29%, 72. 7% and 88.4%, respectively in diagnosis of lumenal narrowing of coronary artery branches. Con- clusions： DSCT is a reliable, safe, simpleand non - invasive test in diagnosis of pa- tients with diabetes and coronary heart dis- ease,and it play a important role in scan- ning and diagnosing coronary heart disease in diabetics.
