左心室PFR图像对老年冠心病诊断的临床意义

Clinical significance of left ventricular peak filling rate imaging for the diagnosis of coronary artery diseased elderly

采用平衡法放射性核素心室造影左心室高峰充盈率（PFR）图像研究42例冠心病患者，其中非心肌梗死组27例，陈旧性心肌梗死组15例，并与19例对照组进行了对比分析。结果证明，左心室PFR图像对冠心病非心肌梗死和陈旧性心肌梗死患者检出率分别为96．3％和100．0％．而且左心室PFR图像对冠心病的诊断．既能定位．又可观察缺血局部功能变化，对全面掌握病情、指导临床治疗具有重要意义。

Left ventricular peak filling rate imaging of equilibrium radionuclide ventriculography was performed in 42 aged patients with coronary artery disease(27 nonmyocardial infarction and 15 obsoluted myocardial infarction) and 19 normal subjects. The results showed that the sensitivity of left ventricular peak filling rate irnaging to evaluated nonmyocardial infarction and obsolute myocardial infarction were 96. 3% and 100% respetively. Th results indicated that left ventricular peak filling rate irnaging was useful in detecting the patients condition and for evaluation of the efficacv after clinical treatment.
