颈动脉超声、核素心肌显像与冠状动脉造影诊断冠心病的对比研究

Comparative study of carotid artery ultrasound,myocardial nuclide imaging,and coronary angiography in diagnosis of coronary heart disease

目的探讨颈动脉超声、核素心肌灌注显像对冠心病的诊断价值。方法对88例疑有冠心病者,以冠状动脉造影结果作为诊断标准,进行颈动脉超声检查和核素心肌灌注断层显像两种检查,并将结果进行对比分析。结果颈动脉超声诊断冠心病的敏感性为65.5%,特异性为73.3%。核素心肌灌注显像诊断冠心病的敏感性为86.2%,特异性为66.7%。结论颈动脉超声结合核素心肌灌注显像诊断冠心病,敏感性与特异性较高,对冠心病的无创性诊断具有重要价值。

Objective To investigate the diagnostic value of carotid artery ttltrasound and myocardial nuclide imaging in coronary heart disease. Methods The study were performed on 88 patients received coronary angiography, carotid artery ttltrasound and myocardial nuclide imaging. Results The sensitivity of myocardial nuclide imaging （86.2%） was significantly higher than that of carotid artery ttltrasound （65.5 % ）, where as the specificity of myocardial nuclide imaging （73.3 % ） did not significantly differ from that of myocardial nuclide imaging （66.7%）.Conclusions Carotid artery ttltrasound and myocardial nuclide imaging are of great value in the diagnosis of coronary heart disease.
