Design outcomes

Primary

MeasureTime frame
1. rest/stress myocardial blood flow by CTP (MBF-CTP) & coronary flow reserve by CTP (CFR-CTP), rest/stress myocardial blood flow by PET (MBF-PET) & coronary flow reserve by PET (CFR-PET), 2. prognosis: all cause death, cardiac death, acute coronary syndrome, admission for ischemic heart disease, target lesion revascularization (TLR), target vessel revascularization (TVR)

Secondary

MeasureTime frame
1. angina scale (SAQ: Seattle Angina Questionnaire) 2. qualitative analysis by CTP & PET 3. evaluation of myocardial ischemia with other modalities: MR perfusion, SPECT, echo 4. quantitative flow ratio (QFR) by CTP 5. QCA 6. FFR, iFR 7. contrast medium, radiation dose
