心肌灌注显像中潘生丁试验与踏车运动试验对冠心病诊断价值的比较

Comparison of the Sensitivity and Specificity of Dipyridamole and Exercise Myocardial Perfusion Planar Imaging for Detection of CHD

为比较潘生了试验和踏车运动试验心肌灌注平面显像诊断冠心病的灵敏度和特异性，我们将100例胸痛患者随机分为两组，分别进行两种试验介人心肌灌注显像，并与冠状动脉造影结果对照。结果：两种介入性试验平面心肌灌注显像，对冠心病诊断的灵敏度分别为：94.59％和92％；特异性分别为80.95％和80％；且对识别冠脉单支，双支，三支管的灵敏度，诊断不同冠脉分支病变的灵敏度，以及检出相应病变血管的灵敏度等各项指标，两组之间对照均无显著性差异。表明：潘生丁试验和踏车运动试验介人心肌灌注平面显像，均可为临床冠心病的诊断和病变的定位提供较可靠的依据。

100 patients with chest pain were randomly divided into two groups to compare the sensitivities and specificities of dipyridamole and exercise myocardial perfusion planar imaging for detection of coronary heart disease using coronary angiographic results as a valid criteria. RESULTS: The sensitivity and specificity were 94. 59% and 80. 95 % for dipyridamole group and 92% and 80 % for exercise group respectively. There were no significant differences in diagnostic sensitivity between those two methods when comparing the patients with single or multiple vesseldiseases, and the Patients with different coronary artery subbrantheS. CONCLUSIONS: The dipyridamole and exercise myocardial perfusion imaging were considered to be similar to each other, both of them are valuable methods for the diagnosis and localization of coronary artery disease.
