摘要
采用小剂量多巴酚丁胺（Ｄｏｂ）负荷试验与核素心室造影（ＲＮＶ）相结合的方法（ＤｏｂＲＮＶ）对２０例陈旧性心肌梗塞（ＯＭＩ）患者进行存活心肌的评估并与２０１铊（Ｔｌ）再注射心肌断层显像（ＳＰＥＣＴ）相比较。结果显示：静态ＲＮＶ明显地低估存活心肌的程度，ＤｏｂＲＮＶ将静态ＲＮＶ对存活心肌的检出率增加６１．５％。以２０１Ｔ１再注射心肌ＳＰＥＣＴ为标准，ＤｏｂＲＮＶ检测存活心肌的阳性预测率为９３．８％，阴性预测率为８０％，预测准确率为８８．５％。
We evaluated the accuracy of low dose dobutamine radionuclide ventriculography (Dob RNV) for detecting myocardial viability. Dob RNV was performed and compared with reinjection of 201 Tl imaging in 20 patients with old myocardial infarction. When resting RNV under 201 Tl estimated the viable myocardium, the detecting rate of which was increased by 61.5% with Dob RNV. So resting RNV is not reliable in identifying myocardial viability, and low dose Dob RNV can significantly improve the detecting rate of viable myocardium. In comparing low dose Dob RNV with 201 Tl myocardial imaging, the positive predictive value of the former for detecting viable myocardium was 93.8%, the negative predictive value 80.0%, and the accuracy 88.5%. Dob RNV is a reliable and noninvasive method for assessing myocardial viability.
