Coronary artery involvement in children with Kawasaki disease: risk factors from analysis of serial normalized...

Area of Science:

• Pediatric Cardiology
• Rheumatology
• Immunology

Background:

• Kawasaki disease often involves coronary arteries.
• Traditional diagnostic criteria may not capture the full spectrum of coronary artery involvement.
• Risk factors associated with coronary artery abnormalities require further investigation.

Purpose of the Study:

• To analyze serial normalized coronary artery measurements in Kawasaki disease patients.
• To identify risk factors associated with coronary artery involvement using a continuous spectrum approach.
• To compare findings with traditional dichotomous criteria.

Main Methods:

• Examined clinical, laboratory, and echocardiographic data from 190 Kawasaki disease patients.
• Calculated maximum coronary artery z scores normalized to body surface area at baseline, 1 week, and 5 weeks.
• Utilized statistical analysis to identify independent risk factors for elevated z scores.

Main Results:

• Coronary artery z scores were significantly elevated at all time points, decreasing over time.
• 26% of patients had a maximal z score >= 2.5, while 23% met Japanese Ministry of Health criteria.
• Younger age, delayed intravenous immunoglobulin treatment, lower IgM, and lower albumin were associated with higher z scores.

Conclusions:

• Serial normalized coronary artery measurements are greatest at baseline and decrease with optimal treatment.
• Baseline measurements predict early follow-up involvement.
• Risk factors identified using precise assessment align with those from dichotomous criteria.
