Abstract 199: Vasospastic Angina In A School Child Long After Kawasaki Disease
Bibliographic record
Abstract
Though it has been already reported that the endothelial function was impaired in patients with a history of Kawasaki disease (KD) and coronary artery aneurysms, vasospastic angina has been rarely reported, especially in school child. A 13-year-old school child referred to us because of repeated chest pain on exercise and reverse redistribution in myocardial perfusion scan. His past history included KD at 2 years of age that was complicated by resistance to initial immunoglobulin treatment and he was left with coronary aneurysms; left main trunk (LMT) of 6.1mm, left anterior descending artery (LAD) of 6.0mm, and right coronary artery (RCA) of 6.0mm. He received oral warfarin treatment in addition to aspirin for 2 years and since then aspirin alone. Coronary angiogram at 7 years old showed LMT aneurysm of 6.1mm starting from orifice extending to bifurcation and regression of RCA aneurysm. He joined baseball club since 8 years old and has been doing well without any symptoms. In this summer, he started complain chest pain after 10 minutes of running 2-3 times a week that lasts for about 30 minutes. Though exercise stress test using treadmill did not show any abnormal electrocardiographic finding, stress myocardial perfusion scan using Thallous chloride-201Tl showed an area of reverse redistribution in the LAD territory. Baseline coronary angiogram at this time showed basically the same finding as that in the last study, intact RCA without stenosis and LMT aneurysm without any stenosis. However, provocative study using intra-coronary administration of 100 ug of acetylcholine, showed diffuse coronary artery spasm in all LCA branches and he indeed complained the same chest pain as that felt in exercise. In addition, intra-coronary administration of nitroglycerine completely reversed coronary spasm and chest pain. Conclusion: Vasospastic angina with chest pain can occurred in the school child with coronary artery aneurysms without coronary stenosis long after KD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
