Clinical Likelihood Prediction of Hemodynamically Obstructive Coronary Artery Disease in Patients With Stable Chest Pain

JACC Cardiovasc ImagingPublished

  • Diagnostic accuracy study

Authors' conclusion

The RF-CL and CACS-CL models are well calibrated and superior to a currently recommended basic PTP model to predict hemodynamically obstructive CAD.

Study context

Population
Stable de novo chest pain patients undergoing coronary CT angiography and invasive coronary angiography with fractional flow reserve (FFR)447 (10.9%) with obstructive coronary artery disease (CAD)
Participants
4,371 patients
Comparison
RF-CL and CACS-CL models vs basic PTP model
Outcome
Hemodynamically obstructive CAD (invasive FFR ≤0.80 or >90% diameter stenosis)

Performance

As reported in the abstract

Very low clinical likelihood (≤5%) of obstructive CAD

P < 0.001

Preserved low prevalence of hemodynamically obstructive CAD in very-low-likelihood patients
<5% for all models
