本文研究~(201)铊显象定量运动试验预测经皮冠状动脉腔内成形术(PTCA)后短期转归的价值。方法病例选择标准:(1)单支冠状动脉病变患者 PTCA 后经造影证实成功;(2)术后2月内做~(201)铊显象定量运动试验;(3)无冠状动脉搭桥术史;(4)PTCA 后所作运动试验前无心绞痛。平均53岁的68(男45,女23)例 PTCA 成功后无症状病人中,64例(94%)术前有Ⅲ或Ⅳ级心绞痛,21例有心肌梗塞史。在 PTCA 后2.2±1.2(1～6)周,按照 Bruce 或 Nanghton 方案进行活动平板试验。62例(97%)因症状运动受到限制,2例(3%)因心率达120bpm。心肌显
This study was to investigate the value of ~ (201) thallium imaging quantitative exercise test in predicting short-term outcomes after percutaneous transluminal coronary angioplasty (PTCA). Methods Case selection criteria: (1) coronary angiography was confirmed by angiography after PTCA in patients with single coronary artery disease; (2) quantitative exercise test of thallium (201) was performed within 2 months after surgery; (3) coronary artery bypass surgery ; (4) no exercise after angina pectoris before exercise test. Of the 68 asymptomatic patients (male 45, female 23) who were 53 years old with PTCA, 64 (94%) had class Ⅲ or Ⅳ angina preoperatively and 21 had a history of myocardial infarction. At 2.2 ± 1.2 weeks (1-6 weeks) after PTCA, the activity plate test was performed according to the Bruce or Nanghton protocol. Sixty-two patients (97%) were limited by symptoms and 2 (3%) had 120bpm heart rate. Myocardial significant
