Abstract 157: Functional and Structural Intermediate Vascular Phenotypes Relating to Long-Term Cardiovascular Risk in Kawasaki Disease
Bibliographic record
Abstract
Background: It is uncertain whether Kawasaki disease (KD) increases overall long term cardiovascular risk, especially in those without demonstrable coronary artery lesions. Data from non-invasive vascular assessment, extrapolated from studies of subclinical atherosclerosis, are conflicting. Methods: Patients at least 2 years post-KD and healthy controls had fasting plasma glucose, lipid profile, high sensitivity C-reactive protein, carotid-femoral pulse wave velocity (PWV), carotid intima-media thickness (cIMT), abdominal aorta intima-media thickness (aIMT), retinal vascular calibre, carotid and aortic elastography performed. Results: 37 controls and 45 patients with KD (21 with regressed or persistent coronary artery changes) were studied at mean ± sd of 10.5 ± 5.7 years following KD. Compared to controls, KD patients did not have increased traditional cardiovascular risk factors; blood pressure, body mass index, waist-to-hip ratio, glucose, cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride and smoking history. Of the cohort, 26 patients (age 15.38 ± 6.19 years) and 27 controls (age 18.7 ± 7.11 years) have had cIMT, aIMT and carotid elastography analysed. The maximum aIMT in KD patients was 0.65 ± 0.15 mm, compared to 0.63 ± 0.13 mm in controls, with the most marked difference in those with coronary artery changes at 0.68 ± 0.14 mm. After adjusting for age, sex, systolic blood pressure, aortic diastolic diameter and high sensitivity C- reactive protein, the average maximum aIMT in all KD patients was 0.071mm larger (95% CI -0.005, 0.147) than controls. Aortic elastography and Doppler pulse wave analysis are underway. Otherwise, there are no detectible differences in PWV, cIMT, carotid elastography, or retinal vascular calibre between KD patients and controls. Conclusion: Compared to carotid artery characteristics, changes in the abdominal aorta may be more discriminative markers of long-term cardiovascular risk in KD. Focus on large arteries in longitudinal KD vascular studies are warranted. Recruitment and analysis are ongoing and further results will be presented.

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.
