64排螺旋CT对早期冠心病的诊疗价值

Diagnosis value of 64-slice spiral CT on early coronary heart disease

目的探讨64排螺旋CT对早期冠心病的诊疗价值。方法选择早期冠心病患者100例，均行螺旋CT冠状动脉成像及冠状动脉造影。比较两种检查方法对冠脉病变的显示情况，并对冠状动脉斑块进行分析。结果两种检查方法对冠状动脉轻、中、重度及闭塞显示情况差异无统计学意义（P〉0．05）。以冠状动脉造影为金标准，64排螺旋CT冠状动脉成像对冠状动脉狭窄敏感性、特异性、阳性预测率、阴性预测率分别为96．4％、96．8％、93．8％、98．2％。64排螺旋CT对脂质斑块、混合型斑块及钙化斑块的检出数量分别为54、46、46处。结论在冠心病的诊断中，64排螺旋CT冠状动脉成像具有很高的敏感性及特异性，并能够评价冠脉斑块，具有很高的临床应用价值。

Objective To investigate the diagnosis and treatment value of 64-slice spiral CT on early coronary heart disease. Methods One hundred patients with early coronary artery disease were chosen, they all underwent spiral CT coronary artery imaging and coronary angiography. The display of coronary artery disease by the two methods was compared, and the coronary plaque was analyzed. Re- sults Both methods for the inspection of coronary mild, moderate, severe and occlusion showed no sig- nificant difference （P 〉 0. 05 ）. With coronary angiography as the gold standard, the sensitivity, specifici- ty, positive predictive value, negative predictive value of 64-slice spiral CT coronary artery imaging for coronary artery stenosis was 96.4% , 96. 8% , 93.8% , 98.2%. The 64 row spiral CT showed 54 lipid plaques, 46 mixed plaques and 46 calcified plaques. Conclusions In the diagnosis of coronary artery disease, 64-slice spiral CT coronary artery imaging has high sensitivity and specificity, and has the ability to evaluate coronary plaque, so it has high clinical value.
