Impact of Stress CT Myocardial Perfusion on Downstream Resources and Prognosis

Summary

CT myocardial perfusion imaging (CTP) represents one of the newly developed CT-based techniques but its cost-effectiveness in the clinical pathway is undefined. The aim of the study is to evaluate the usefulness of combined evaluation of coronary anatomy and myocardial perfusion in intermediate to high-risk patients for suspected CAD or with known disease in terms of clinical decision-making, resource utilization and outcomes in a broad variety of geographic areas and patient subgroups.

Conditions

• Coronary Artery Disease
• Myocardial Ischemia

Interventions

DIAGNOSTIC_TEST

Integration of CCTA with stress CTP when indicated

When judged indicated, functional assessment with stress CTP perfusion will be performed on top of CCTA.

DIAGNOSTIC_TEST

Standard of care approach

(a) functional non-invasive tests (stress ECG, or imaging-based tests such as Stress Echo, Stress CMR, SPECT or PET) as a gatekeeper for ICA; (b) direct referral to ICA.
