摘要
目的研究CTA对糖尿病患者冠状动脉狭窄的诊断价值。方法选取我院2012年3月至2015年9月134例糖尿病患者为研究对象,采用CTA和冠状动脉造影检查,以冠状动脉造影为金标准,评估冠状动脉狭窄程度。结果 CTA诊断冠状动脉狭窄程度≥50%的诊断敏感性为95.97%,特异性为92.42%,阳性预测值为92.94%,阴性预测值为90.37%,准确率为92.74%,Kappa值为0.85。结论 CTA对冠状动脉狭窄的显示具有较高的准确性,是诊断糖尿病患者冠状动脉病变可靠、无创的检查方法。
Objective To study the diagnostic value of CTA diagnosing the diabetic patients with coronary stenosis. Methods 134 cases of diabetic patients admitted and treated in our hospital during March 2012 and September 2015 were selected as the study objectives. All patients were given CTA and coronary arteriography. And the results of coronary arteriography were taken as the golden standard to evaluate the degree of coronary stenosis, Results The sensitivity of diagnosis for the degree of coronary stenosis （≥50%） diagnosed through CTA was 95.97%, the specificity was 92.42%, the positive predictive value was 92.94% ,the negative predictive value was 90.37%, the accuracy rate was 92.74% and the Kappa value was 0.85. Conclusion eTA is highly accurate in revealing the coronary stenosis. Thus, CTA is a reliable and noninvasive examination in diagnosing the diabetic patients with coronary stenosis.
