NCT05593120

Brief Summary

To determine whether, in a Chinese population of patients presenting to Wuhan Asia Heart Hospital, Fractional Flow Reserve Derived from Coronary Computed Tomography Angiography (CT-FFR) as a default test is noninferior in terms of total costs when compared to routine clinical pathway recommended by the investigator and the institution's heart team.

Outcome Measures

Primary Outcomes (1)

  • Resource utilisation

    To determine whether, in a Chinese population of patients presenting to Wuhan Asia Heart Hospital, CT-FFR as a default test is noninferior in terms of total costs when compared to routine clinical pathway recommended by the investigator and the institution's heart team. Comparison of resource utilization between two groups at 180 days (+30/-15 days).

    6 months

Secondary Outcomes (1)

  • time period between initial consultation and definitive management plan

    6 months

Study Arms (2)

CT-FFR

All patients will be assessed and managed according to the results of CT-FFR test, assuming they have no prespecified contraindications to CT coronary angiography. The result of the CT-FFR will be conveyed to the supervising physician within 24 hours and will be used to determine the subsequent management plan.

Diagnostic Test: CT-FFR

Routine care

All patients will be assessed and managed exactly as they are usually treated by the investigator and the institution's heart team according to routine practice in Wuhan Asia Heart Hospital.

Diagnostic Test: Routine care

Interventions

CT-FFRDIAGNOSTIC_TEST

In the test group all patients who are eligible for CTA will undergo CTA as their default test. Those patients with any coronary stenosis 30%-90% data in at least one major epicardial vessel will be referred for CT-FFR. In patients in whom CT-FFR analysis is performed, FFR will be derived for all vessels. CT-FFR will be evaluated in a blinded fashion with a "Coarse-to-Fine Subpixel" algorithm for lumen contour. The data derived from this test will determine their management strategy.

CT-FFR
Routine careDIAGNOSTIC_TEST

All patients in the routine care group will be assessed according to their current conventional pathways that are based upon routine practice in Wuhan Asia Heart Hospital. The trial will encourage the routine and standard assessment and management of all patients (anticipated outcomes include ETT, stress echo, stress MR, nuclear perfusion, CTA, CT calcium, invasive CA, reassurance).
