目的评价N-13-氨正电子发射断层显像（PET）心肌灌注显像和冠状动脉血流储备（CFR）对疑似心肌缺血患者长期预后的预测价值。随访245例（96%）。排除了16例早期血运重建的患者，229例被分配为正常与异常灌注或正常与异常CFR。
Objectives The goal of this study was to assess the predictive value of myocardial perfusion imaging with N-13-ammonia positron emission tomography (PET) and coronary flow reserve (CFR) on long-term prognosis in patients with suspected myocardial ischemia.Background No prognostic data exist on the predictive value of CFR and N-13-ammonia PET.Methods Perfusion and CFR were assessed in 256 patients using N-13-ammonia PET, and follow-up was obtained in 245 (96%) patients. Sixteen early revascularized patients were excluded and 229 were assigned to normal versus abnormal perfusion or normal versus abnormal CFR (
