摘　　要：目的探讨128层螺旋CT冠状动脉成像在诊断冠心病中的应用价值。方法选择40例临床可疑的冠心病患者及5例冠状动脉支架术后患者,均对其行128层螺旋CT冠状动脉成像,并与冠状动脉造影结果进行对比。结果以冠状动脉造影为金标准,128层螺旋CT冠状动脉成像诊断冠状动脉狭窄的敏感性为89.3%,特异性为97%,阳性预测值为86.2%,阴性预测值为97.7%。结论 128层螺旋CT冠状动脉成像作为一种具有非创伤性、安全性的检查方法,在诊断冠状动脉狭窄、显示粥样硬化斑块、冠脉支架术后患者的复查等方面有一定的临床价值,可作为冠心病高危人群的一种无创筛查手段,并可用于冠脉支架术后随访。Objective To evaluate the effectiveness of application of 128-slice spiral CTCA（Computerized Tomography Coronary Angiography） in diagnosis of CHD（Coronary Heart Disease）.Methods Forty cases of suspected CHD patients and 5 cases with a previously implanted coronary stent were selected and scanned by 128-slice spiral CTCA so as to compare its imaging results with conventional CAG（Coronary Angiography）.Results With CAG as the gold standard,the sensitivity,specificity,PPV and NPV（Positive and Negative Predictive Value） of 128-slice spiral CTCA were 89.3%,97%,86.2% and 97.7% respectively in diagnosis of coronary artery stenosis.Conclusion The 128-slice spiral CTCA demonstrated its excellent clinical effectiveness in diagnosing coronary artery stenosis,revealing coronary atherosclerotic plaques and re-examining patients with a previously implanted coronary stent,which can be used as a noninvasive and safe screening method for people at high risk of developing CHD and also as a follow-up method for patients with a previously implanted coronary stent.
