Sixty six patients with angina at rest were investigated by exercise electrocardiography, thallium scintigraphy, and coronary arteriography. A positive exercise electrocardiogram was highly predictive (93%) but poorly sensitive (52%) of coronary artery disease (greater than or equal to 50% stenosis). Thallium scintigraphy was as predictive of the presence of coronary artery disease (91%) but was also highly sensitive (91%). The diagnostic contribution of the thallium scan was greatest in those patients with an inconclusive exercise electrocardiogram without Q waves.
66例静息性心绞痛患者接受了运动心电图、铊闪烁扫描及冠状动脉造影检查。运动心电图阳性对冠状动脉疾病（狭窄≥50%）具有高度预测性（93%），但敏感性较差（52%）。铊闪烁扫描对冠状动脉疾病的存在具有同样的预测性（91%），且敏感性也很高（91%）。铊扫描对运动心电图无Q波且结果不确定的患者诊断贡献最大。
