NCT02264717

Brief Summary

1\. The primary purpose of this study is to determine the diagnostic accuracy of the CADscore System, a new danish technology that records sounds from turbulence of bloodflow in the coronary vessels. And secondary:

  1. 1.To determine the accuracy of cardiac magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT), as secondary tests after detection of obstructive anatomic coronary artery stenosis by coronary computed tomographic angiography (CCTA).
  2. 2.To examine the patient population for bio-genetic markers related to development of arteriosclerosis.
  3. 3.To evaluate virtual fractional flow reserve (vFFR) computed from coronary angiograms.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy of the CADscore system compared to CCTA and CCA-QCA.

    Diagnostic precision will be evaluated as the AUC-ROC. The CADscore will be dichotomized at cut off values of 20,25 and 30 and performance reported with sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy. The CADscore system operates with 3 intervals of risk stratification: \<20, 20-30, \>30 (low, intermedia and high risk of cardio vascular disease, respectively) Obstructive CAD is defined as ≥ 50% diameter stenosis as determined by quantitative analysis of CCA (QCA). Non-Obstructive CAD is defined as no detection of obstructive anatomic coronary artery stenosis by CCTA or stenosis detected by CCTA combined with a evaluation by CCA-QCA demonstrating a luminal stenosis diameter \< 50 %.

    Within one week before or after CCTA

Secondary Outcomes (2)

  • Safety of CADScore Safety of CADScore

    One week after the use of CADScore

  • Diagnostic accuracy of the CADScore system compared to CCA-FFR.

    Within four weeks after CADScore

Other Outcomes (3)

  • Feasibility of virtual FFR

    one day

  • Diagnostic accuracy of virtual FFR

    one day

  • The diagnostic accuracy of perfusion imaging (Cardiac MRI and SPECT)

    Within 4 weeks after the CCTA
