虽有典型心绞痛病史但是心电图运动试验阴性的患者构成一个独特的亚组,这些患者患有冠心病和日后发生心脏病事件的危险性中等。本文回顾分析~(201)铊(重分布)运动试验在这些患者中的预后价值。病例选自1979年12月至1985年7月间在 Cedars-Sinai 医学中心进行~(201)铊运动试验的典型心绞痛患者,~(201)铊运动试验后60天内(早期)曾作冠状动脉旁路移植术(CABG)或者经皮冠状动脉腔内成形术(PTCA)的患者已经除外。按照 Bruce 方案进行症状限制性极量活动平板试验:A 组190例阴性,B 组203例阳性。预期最快心率即
Patients who have a history of classic angina but have negative electrocardiogram test results in a unique subgroup of patients who have a moderate risk of having coronary heart disease and future cardiac events. This article reviews the prognostic value of ~ (201) Thallium (redistribution) exercise testing in these patients. The patients were selected from the group of typical angina patients who underwent the ~ 201 thallium exercise test at the Cedars-Sinai Medical Center between December 1979 and July 1985, and coronary arteries were placed within 60 days of the ~ (201) thallium exercise test (early) Patients who have undergone CABG or PTCA have been excluded. The Bruce regimen was used to conduct a maximally restrictive, plateau test of symptoms: 190 in group A were negative and 203 in group B were positive. The fastest heart rate that is expected
