中国循环杂志99zk85 目的：采用小剂量多巴酚丁胺彩色动力超声心动图评价血管重建术后的心肌存活性。
方法：45例经冠状动脉造影证实的冠心病患者进入本试验，在5～20 μg/(kg*min)的多巴酚丁胺静脉滴注下，应用彩色动力超声心动图观察缺血区的彩色变化，并与血管重建术后进行比较，以识别有无存活心肌。
结果：45例冠心病基础状态室壁运动异常69节段，其中30例行血管重建术的患者药物试验中及术后的室壁运动肌酸激酶时间定量值明显高于术前(P<0.05)。其诊断心肌活性的敏感性为96.15%，特异性为75%，准确性为93.33%。
结论：小剂量多巴酚丁胺彩色动力超声心动图对血管重建术存活心肌的检测是安全的，具有十分重要的临床意义。

Objective: To observe myocardial viability in patients after revascularization by color kinesis (CK) echocardiography during infusion of dobutamine.
Methods: We studied 45 patients with coronary artery disease (CAD) dignosed by coronary arteriography. During infusion of dobutamine 5～20 μg/(kg*min), we observed color change in ischemic segments and compared that before and after revascularization by CK echocardiography in order to identify myocardial viability.
Results: 69 abnormal segments of wall motion were observed at rest in 45 patients with CAD. Quantitative analysis of CK in ischemic segments during infusion of dobutamine and after revascularization demon that it was higher than that in those segments at rest (p<0.05) in 30 patients. Sensitivity, specificity and accuracy of low dose dobutamine CK echocardiography for predicting myocardial viability were 96.15%, 75%, 93.33%, respectively.
Conclusion: CK echocardiography during infusion of low dose dobutamine is a safe method and of certain clinical significance for identifying myocardial viability in patients with CAD., http://www.100md.com
