【摘要】 目 的 比较多巴酚丁胺和运动^99m 锝-焦磷酸盐心肌显像诊断冠心病的价值。方法 对120例拟诊为冠心病的患者分别进行药物和运动负荷^99m 锝-焦磷酸盐心肌显像，最后经冠状动脉造影确诊为冠心病。结果 多巴酚丁胺负荷诊断冠心病的敏感性为94.3%，特异性为88%，准确性91.7%，显著高于运动负荷的75%，61%和68.4%，(P<0.01)。结论 多巴酚丁胺对于诊断冠心病具有较高的敏感性和特异性。

【 Abstract】 Objective The aim of this study is to compare the values ofdobutamine (DB-T) stress test and exercise (Ex) ^99m Tc-MIBI myocardial imaging in the diagnosis of coronaryheart disease (CHD). Methods 120 patients suspected of CHD underwent pharmacologic and exercisestress ^99m Tc-MIBImyocardial imaging. Among them, 70 cases were confirmed CHD by coronary angiography, 50cases were excepted. Results The overall sensitivity, specificity and accuracy for detecting CHDbetween DB-T and Ex were different significantly (94.3% vs 75%; 88% vs 61% and 91.7% vs68.4%, P<0.01, respectively). Conclusion These results suggested much higher sensitivity and specificity inDB-T stress test than in Ex stress.
