To determine whether normal exercise images can reduce the need for coronary arteriography, we analyzed our data on 102 patients with normal thallium 201 exercise images who underwent coronary arteriographic studies. Eight-two patients had normal or insignificant coronary artery disease; 20 patients had significant coronary artery disease. Eight patients had disease limited to one of the secondary branches of the left system; seven patients had disease limited to one of the major coronary arteries; two patients had disease involving the right coronary artery and a secondary branch; two patients had disease involving two secondary branches; and one patient had disease involving the three major vessels. Seven of the 20 patients had abnormal exercise ECGs, and the remaining 13 patients had normal or inconclusive exercise ECGs. Our findings indicate that significant coronary artery disease is rare in patients with normal exercise images, especially if patients with abnormal exercise ECGs are excluded. Thus, normal exercise images could possibly reduce the need for coronary arteriography, since in these patients coronary artery disease rarely requires bypass surgery.
为了确定正常运动图像是否能减少冠状动脉造影的需求，我们分析了102例接受冠状动脉造影研究且铊201运动图像正常的患者的数据。82例患者有正常或轻微的冠状动脉疾病；20例患者有严重的冠状动脉疾病。8例患者的疾病局限于左系统的一个二级分支；7例患者的疾病局限于一条主要冠状动脉；2例患者的疾病累及右冠状动脉和一个二级分支；2例患者的疾病累及两个二级分支；1例患者的疾病累及三条主要血管。20例患者中有7例运动心电图异常，其余13例患者运动心电图正常或不确定。我们的研究结果表明，运动图像正常的患者中严重冠状动脉疾病很少见，尤其是排除运动心电图异常的患者后。因此，正常运动图像可能会减少冠状动脉造影的需求，因为在这些患者中冠状动脉疾病很少需要进行搭桥手术。
