Outcome Measures
Primary Outcomes (3)
The average number of invasive procedures (coronary angiography/PCI) in the arm: A. Angio - CT versus B. Classic diagnostics (superiority)
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
The proportion of "avoidable" invasive diagnostic procedures (coronary angiographies not followed by an intervention) in the arm: A. Angio-CT versus B. Classic diagnostics (superiority)
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
Composite outcome of: myocardial infarction, death, acute coronary syndrome, unplanned coronary revascularization, hospitalization for cardiovascular reason, stroke
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
Secondary Outcomes (8)
composite outcome: number of serious adverse events during diagnosis and treatment of coronary artery disease
up to 36 months (through study completion)
Time to occurrence of composite outcome of: myocardial infarction, death, acute coronary syndrome, unplanned coronary revascularization (including restenosis), urgent hospitalization for cardiovascular reason, stroke
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
Time to occurrence of composite outcome of: myocardial infarction, death, acute coronary syndrome, unplanned coronary revascularization (including restenosis), urgent hospitalization for cardiovascular reason, stroke
up to 36 months (through study completion)
Number of angioplasty procedures performed in accordance with ESC recommendations where the treatment planned on the basis of CT angiography by an interventional cardiologist is not treated ad-hoc.
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
Average number of therapeutic procedures (PCI/CABG).
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
- +3 more secondary outcomes
Other Outcomes (2)
The volume of contrast agent used for diagnosis and possible coronary intervention in the arm: A. Angio-CT versus B. Classic diagnostics (non-inferiority)
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
The radiation dose used for diagnosis of coronary artery disease and possible intervention in the arm: A. Angio-CT versus B. Classic diagnostics (non-inferiority)
up to 3 months (until the last diagnostic/therapeutic procedure; it is assumed it will be completed within 3 months of the participants study entry).
Study Arms (2)
Cardiac CT
ACTIVE COMPARATOR60 patients with high pre-test probability o coronary artery disease will be randomly chosen and undergo computed tomography angiography (cardiac CT) as the first-choice imaging diagnostics
Invasive coronary angiography
ACTIVE COMPARATOR60 patients with high pre-test probability o coronary artery disease will be randomly chosen and undergo invasive coronary angiography
Interventions
Performation of non-invasive cardiac CT angiogram
Patient undergoes invasive coronary angiography
