64排螺旋CT冠状动脉成像对冠心病合并糖尿病患者冠脉病变的诊断价值研究

摘要

目的 评价64排螺旋CT冠状动脉成像在冠心病(CAD)合并糖尿病患者冠状动脉病变诊断中的价值. 方法 345例应用64排螺旋CT疑诊为CAD的糖尿病患者,以冠状动脉造影(CAG)结果为金指标,评价64排螺旋CT在CAD诊断中的价值.对3 568支冠状动脉血管进行选择性CAG检查,将两种方法的检查结果进行对照分析. 结果 64排螺旋CT对冠状动脉狭窄的诊断与CAG比较,差异无统计学意义(P＞0.05).64排螺旋CT显示多排螺旋CT血管造影(MSCTA)诊断冠状动脉狭窄有较高的敏感性、特异性、阳性预测值及阴性预测值. 结论 64排螺旋CT冠状动脉成像技术是一项可靠的CAD诊断方法,作为一项非创伤性检查技术,是评价冠状动脉病变的重要手段.%Objective To evaluate 64-slice CT coronary angiography for diagnosis of coronary artery disease (CAD) in patients with diabetes mellitus. Methods 345 patients with suspected coronary heart disease plus diabetes mellitus were treated with 64-slice CTCA. The coronary artery angiography (CAG) results were the gold standard for evaluating the diagnosis of coronary heart disease (CHD). 3568 coronary arteries were selected for coronary angiography. The results were compared between CAG and CTCA. Results There was no significant difference between 64-slice CTCA and CAG for diagnosis of coronary artery stenosis (P>0. 05). 64-slice CTCA for diagnosis of coronary artery stenosis had high sensitivity, specificity, positive predictive value and negative predictive value. Conclusions 64-slice CT coronary artery imaging as a non-invasive inspection technology is a reliable diagnostic method for screening coronary heart disease.
