NCT02591992

Brief Summary

To evaluate the safety and effectiveness of computed tomography angiography in the diagnostic and therapeutic cycle as the first-choice method of imaging in the diagnosis of patients with a high probability of stable coronary artery disease according to European Society of Cardiology recommendations.

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 COMPARATOR

60 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

Other: Cardiac CT as the first diagnostic modality in suspected CAD

Invasive coronary angiography

ACTIVE COMPARATOR

60 patients with high pre-test probability o coronary artery disease will be randomly chosen and undergo invasive coronary angiography

Other: Invasive coronary angiography as indicated by the guidelines

Interventions

Performation of non-invasive cardiac CT angiogram

Cardiac CT

Patient undergoes invasive coronary angiography

Invasive coronary angiography
