We sought to evaluate the prognostic implications of CCTA-derived anatomic and hemodynamic plaque characteristics in the prediction of subsequent coronary events.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study cohort consisted of 158 patients who underwent CCTA with suspected CAD within 6\u201336 months before percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) or unstable angina and age-\/sex-matched 62 patients without PCI as the control group. Preexisting high-risk plaque characteristics (HRPCs: low attenuation plaque, positive remodeling, napkin-ring sign, spotty calcification, minimal luminal area &amp;lt;4 mm<jats:sup>2<\/jats:sup>, or plaque burden \u226570%) and hemodynamic parameters (per-vessel fractional flow reserve [FFRCT], per-lesion \u0394FFR<jats:sub>CT<\/jats:sub>, and percent ischemic myocardial mass) were analyzed from prior CCTA. The primary outcome was a subsequent coronary event, which was defined as a composite of vessel-specific MI or revascularization for unstable angina. The prognostic impact of clinical risk factors, HRPCs, and hemodynamic parameters were compared between vessels with (160 vessels) and without subsequent coronary events (329 vessels).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Vessels with a subsequent coronary event had higher number of HRPCs (2.6 \u00b1 1.4 vs. 2.3 \u00b1 1.4, <jats:italic>P<\/jats:italic> = 0.012), lower FFR<jats:sub>CT<\/jats:sub> (0.76 \u00b1 0.13 vs. 0.82 \u00b1 0.11, <jats:italic>P<\/jats:italic> &amp;lt; 0.001), higher \u0394FFR<jats:sub>CT<\/jats:sub> (0.14 \u00b1 0.12 vs. 0.09 \u00b1 0.08, <jats:italic>P<\/jats:italic> &amp;lt; 0.001), and higher percent ischemic myocardial mass (29.0 \u00b1 18.5 vs. 26.0 \u00b1 18.4, <jats:italic>P<\/jats:italic> = 0.022) than those without a subsequent coronary event. Compared with clinical risk factors, HRPCs and hemodynamic parameters showed higher discriminant abilities for subsequent coronary events with \u0394FFR<jats:sub>CT<\/jats:sub> being the most powerful predictor. HRPCs showed additive discriminant ability to clinical risk factors (c-index 0.620 vs. 0.558, <jats:italic>P<\/jats:italic> = 0.027), and hemodynamic parameters further increased discriminant ability (c-index 0.698 vs. 0.620, <jats:italic>P<\/jats:italic> = 0.001) and reclassification abilities (NRI 0.460, IDI 0.061, <jats:italic>P<\/jats:italic> &amp;lt; 0.001 for all) for subsequent coronary events. Among vessels with negative FFR<jats:sub>CT<\/jats:sub> (&amp;gt;0.80), adding HRPCs into clinical risk factors significantly increased discriminant and reclassification abilities for subsequent coronary events (c-index 0.687 vs. 0.576, <jats:italic>P<\/jats:italic> = 0.005; NRI 0.412, <jats:italic>P<\/jats:italic> = 0.002; IDI 0.064, <jats:italic>P<\/jats:italic> = 0.001) but not for vessels with positive FFR<jats:sub>CT<\/jats:sub> (\u22640.80).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In predicting subsequent coronary events, both HRPCs and hemodynamic parameters by CCTA allow better prediction of subsequent coronary events than clinical risk factors.
