对比研究了32例冠心病患者的多巴酚丁胺负荷核素局部心功能测定和心肌灌注显像,其中11例有冠状动脉造影。结果:两种方法的灵敏度、特异性、准确性均>90%;多巴酚丁胺介入心肌灌注显像检出异常节段(90个)较局部心功能测定(76个)多,显示缺血范围也大,定位较准确,但后者却能定量反映心肌缺血程度及估计预后。结论:两种方法结合有助于临床医生对冠心病的诊断、治疗、预后做出全面评价。
Comparative study of dobutamine stress nuclide local myocardial function and myocardial perfusion imaging in 32 patients with coronary heart disease, of which 11 patients had coronary angiography. Results: The sensitivity, specificity and accuracy of the two methods were all higher than 90%. Dobutamine intervention myocardial perfusion imaging detected more abnormal segments (90) than local cardiac function test (76) Blood is also large, more accurate positioning, but the latter can quantitatively reflect the degree of myocardial ischemia and prognosis. Conclusion: The combination of the two methods can help clinicians make a comprehensive assessment of the diagnosis, treatment and prognosis of coronary heart disease.
