  • "KD is associated with mucocutaneous lymph node syndrome and predominantly affects medium and small arteries in infants and children less than 5 years of age. It is more prevalent in Asian populations and has a male dominance.”

  • “The coronary arteries are often involved in KD and coronary artery aneurysms develop as a result of coronary vasculitis in about 15% to 25% of untreated patients. Coronary artery aneurysms can be classified according to their size (small, <5 mm; medium, 5–8 mm; and large, >8 mm) and shape (saccular or fusiform). Large coronary artery aneurysms are associated with a higher risk of complications such as rupture, thrombosis, and stenosis, which possibly lead to myocardial infarction and death."

  • Conclusion: Compared with Coronary Artery Disease Reporting and Data System and other scores, machine learning methods better discriminated patients who subsequently experienced an adverse event from those who did not.
  • Background: Coronary CT angiography contains prognostic information but the best method to extract these data remains unknown.
    Purpose: To use machine learning to develop a model of vessel features to discriminate between patients with and without subsequent death or cardiovascular events. Performance was compared with that of conventional scores.
    Conclusion: Compared with Coronary Artery Disease Reporting and Data System and other scores, machine learning methods better discriminated patients who subsequently experienced an adverse event from those who did not.

  • Key Points
    * For prediction of all-cause mortality on the basis of coronary CT angiography, the area under the receiver operating characteristic curve (AUC) for a machine learning score was higher than for Coronary Artery Disease Reporting and Data System (CAD- RADS; 0.77 vs 0.72, respectively; P , .001).
    * For prediction of coronary artery deaths on the basis of coronary CT angiography, the AUC was higher for a machine learning score than for CAD-RADS (0.85 vs 0.79, respectively; P , .001).
    * When deciding whether to start statins, a machine learning score ensures 93% of patients with events will be administered the drug; if CAD-RADS is used instead, only 69% will be treated.
