| 摘 要： | 本文利用彩色室壁运动分析技术（ＣｏｌｏｒＫｉｎｅｓｉｓ，简体ＣＫ）与小剂量多巴酚丁胺超声心动图负荷试验（２ＤＥ－ＤＥ）相结合（ＣＫ－ＤＥ），对６条开胸犬心肌顿抑模型进行研究，结果与２ＤＥ－ＤＥ、核素心肌灌注显像和病理检查比较，发现２３个经病理证实的存活心肌节段中ＣＫ－ＤＥ能检出２２个，２ＤＥ－ＤＥ能检出２１个，核素心肌灌注显像以存活分数≥０．１为标准能检出１７个；以存活分数≥０．２为标准能检出１１个。表明ＣＫ－ＤＥ检出存活心肌较核素心肌灌注显像敏感。

| Abstract: | To evaluate the potential of color kinesis(CK)to identify viable myocardium,six canine stunned myocardial models were studied before and after low-dose dobutamine,and the results were compared with conventional twodimensioal echocardiography(2DE),and SPECT.A basically akinetic or hypokinetic segment was considered as viable by CK-DE if color coded increment could be observed after dobutamine.Results:1.Endocardial movement could be properly color coded by CK,2.In 23 segments with viable myocardium,22,21,and 17 segments were considered as viable by CKDE,2D-DE,and SPECT respectively.Conclusion:CK-DE was more sensitive in identifying viable myocardium than SPECT. |
