From 1293 patients who underwent thallium stress testing and 1099 patients who had coronary angiography, a consecutive series of 122 who had both studies is evaluated. This group includes suboptimally exercised patients and those receiving one or several cardiovascular drugs that were not discontinued prior to exercise. When compared with the EKG stress test, thallium stress imaging was superior in sensitivity (80% vs 68%), specificity (84% vs 49%), accuracy (81% vs 62%), positive predictive value, (92% vs 75%), and negative predictive value (65% vs 45%) in this group, with 71% prevalence of angiographically significant coronary artery disease.
对1293例接受铊负荷试验的患者以及1099例接受冠状动脉造影的患者进行评估，选取其中连续的122例同时进行了这两项检查的患者。该组包括运动不足的患者以及在运动前未停用一种或几种心血管药物的患者。与心电图负荷试验相比，在该组中铊负荷显像在敏感性（80%对68%）、特异性（84%对49%）、准确性（81%对62%）、阳性预测值（92%对75%）和阴性预测值（65%对45%）方面更具优势，冠状动脉造影显示有显著冠状动脉疾病的患病率为71%。
