Prediction of lesions causing ischemia by plaque characteristics on coronary computed tomography angiography and optical coherence tomography.

Based on a prospective multicenter registry, this study evaluated the association between the FFR and plaque characteristics assessed using coronary CTA and OCT in patients with intermediate coronary stenosis. In addition to stenosis severity on coronary CTA and OCT, plaque characteristics, including low attenuation plaque on coronary CTA and thrombus, plaque rupture, and intimal vasculature on OCT, were independent predictors for the lesions causing ischemia (FFR ≤0.80).
