A simple, accurate, noninvasive method is required for the objective evaluation of aortocoronary bypass surgery. Stress myocardial imaging with intravenous injection of potassium-43 or thallium-201 was used an average of 4.4 months after direct myocardial revascularization in 77 patients to assess the accuracy of stress myocardial imaging in predicting completeness of revascularization. The results were correlated with maximal treadmill exercise tests, extent of revascularization and status of bypass grafts (occlusion, stenosis and distal disease). We found stress myocardial imaging to be a more sensitive method than the stress electrocardiogram for the detection of incomplete revascularization. The method appears to be a sensitive noninvasive means of evaluating the results of aortocoronary bypass surgery.
需要一种简单、准确、无创的方法来客观评估主动脉冠状动脉搭桥手术。在77例患者直接心肌血运重建术后平均4.4个月，采用静脉注射43钾或201铊进行负荷心肌显像，以评估负荷心肌显像预测血运重建完整性的准确性。将结果与最大运动平板试验、血运重建范围和旁路移植血管状态（闭塞、狭窄和远端病变）进行相关性分析。我们发现，对于检测不完全血运重建，负荷心肌显像比负荷心电图是一种更敏感的方法。该方法似乎是评估主动脉冠状动脉搭桥手术结果的一种敏感的无创手段。
