Official title
Myocardial Perfusion Imaging by 15O-H2O PET/CT: Reference Values and Prognostic Value
Overview
The trial will include 5000 patients with evident or suspected ischemic heart disease refered to Department of Nuclear Medicine \& PET Centre, Aarhus University Hospital, for perfusion imaging by 15O-H2O PET/CT scan of the heart during rest and stress. The patients will undergo the clinical scan as normal. Data from the scans will be used to determine reference values of the examination. Follow up will be done for up to 10 years in regards to major cardiovascular events in order to determine the prognostic value of the scan.
Primary outcome measures
- Prognostic value within 10 years [Time frame: 10 years]
Secondary outcome measures (12)
- Myocardial blood flow [Time frame: 5 Years]
- Coronary flow reserve [Time frame: 5 Years]
- Pulmonary transit time [Time frame: 5 Years]
- Left ventricular end-systolic volume [Time frame: 5 Years]
- Left ventricular end-diastolic volume [Time frame: 5 Years]
- Right ventricular end-systolic volume [Time frame: 5 Years]
- Right ventricular end-diastolic volume [Time frame: 5 Years]
- Immediate coronary angiography followup [Time frame: 5 years]
- Immediate percutaneous coronary intervention (PCI) followup [Time frame: 5 years]
- Immediate coronary artery bypass graft (CABG) followup [Time frame: 5 years]
- Prognostic value within 5 years [Time frame: 5 years]
- Prognostic value within 2 years [Time frame: 2 years]
