Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of QFR

    Diagnostic accuracy of QFR (≤0.80 or \>0.80) to determine hemodynamically significant coronary stenosis using invasive FFR (≤0.80 or \>0.80) as a reference standard

    through study completion, an average of 1 year

Secondary Outcomes (3)

  • Sensitivity of QFR

    through study completion, an average of 1 year

  • Specificity of QFR

    through study completion, an average of 1 year

  • Correlation

    through study completion, an average of 1 year

Study Arms (1)

QFR group

Patients suspected with coronary artery disease undergoing diagnostic coronary angiography with an indication for to perform invasive FFR

Diagnostic Test: QFR

Interventions

QFRDIAGNOSTIC_TEST

Patients suspected with CAD undergoing diagnostic coronary angiography with an indication for to perform invasive FFR were included. QFR was analyzed in an independent core laboratory (Uijeongbu Eulji Medical Center) using the software package QAngio XA 3D 2.1 (Medis Medical Imaging Systems, Leiden, the Netherlands).
