128层螺旋CT冠状动脉成像对冠心病诊断的临床价值

目的:探讨128层螺旋CT冠状动脉成像(128-SCTCA)在冠心病中的临床应用价值。方法:对349例疑似冠心病患者行128-SCTCA筛查,对其中59例患者同时作选择性冠状动脉血管造影(CAG)检查,分析比较128-SCTCA诊断冠心病的敏感性、特异性、阳性预测值、阴性预测值和准确率。结果:341例患者成功完成了128-SCTCA检查,并可清晰显示冠脉主干及其主要分支,193例患者的596支冠脉伴有不同性质的斑块和不同程度的狭窄,对其中59例冠心病患者以CAG为金标准,得出128-SCTCA诊断冠脉狭窄的敏感性、特异性、阳性预测值、阴性预测值及准确率分别为100%、90.23%、92.57%、100%、95.59%。从59例患者的295支冠脉中检测出136个斑块,脂质软斑块、纤维斑块及钙化硬斑块分别占18%、11%、71%。结论:128层CT冠脉成像是一种无创的成像方法,检出冠心病的准确程度高,对冠状动脉狭窄的诊断准确率接近CAG,区分高危斑块优于CAG,作为冠心病的一种无创筛查手段具有很高的临床应用价值。

Clinical value of 128-slice spiral CT coronary angiography in the coronary artery disease

Objective:To explore the clinical value of 128-slice spiral CT coronary angiography(128-SCTCA) in the coronary heart disease diagnosis.Methods:128-SCTCA were performed in 349 patients suspected coronary heart disease,59 of 349 patients underwent selective coronary angiography(CAG),the results of 128-SCTCA were compared with that of CAG.Results:Three hundred and forty-one patients successfully completed 128-SCTCA,the coronary artery branches and the main sub-branches were clearly displayed.596 coronary arter...
