平板运动试验可疑阳性患者的冠状动脉CT及冠状动脉造影结果的相关性研究

目的 探讨平板运动试验(TET)可疑阳性患者的冠状动脉造影(CAG)结果的特点.方法 2006年1月至2007年12月因胸痛住院的36例患者在人院行TET后均诊断为可疑阳性,同时在2周内行CAG检查和冠状动脉CT成像(CTA),并将斑块分为非钙化和钙化斑块.结果 36例患者中,23例经CAG证实为冠心病(阳性),13例冠状动脉无病变(阴性).23例冠心病患者中单支病变9例,双支病变5例,三支病变9例.23例TET可疑阳性冠心病患者CTA共检测52个斑块,其中非钙化斑块29个,钙化斑块23个.结论 TET在冠心病的诊断中因其方法简单、经济、无创,目前仍不失为一项重要检查方法.同时冠心病患者的斑块性质与TET可疑阳性具有相关性.

The characteristics of the results of coronary artery CT angiography and coronary artery angiography in 36 patients with probable positive results of treadmill exercise test

Objective To investigate the clinical characteristics of the results of coronary artery CT angiography and coronary artery angiography in 36 patients with probable positive results of treadmill exercise test(TET).Methods Thirty-six patients due to chest pain received 1ET and coronary artery CT angiography and coronary artery angiography in 2 weeks after admission.The coronary plaques were categorized as noncalcified and calcified plaque on CTA images.Results In 36 patients with probable positive results of TET.23 patients were confirmed as coronary artery disease by coronary artery angiography,and the other 13patients had normal coronary artery.Of 23 coronary artery disease patients,9 patients were presented as onevessel disease,5 patients were presented as two-vessel disease,and 9 patients were presented as three-vessel disease,29 non-calcified plaques and 23 calcified plaques were demeted On CTA.Conclusion TET was useful in confirming the diagnosis of coronary artery disease.The characteristics of the coronary artery plaque is correlated with probable positive results of TET.
