Insights
Most Kawasaki disease cardiac sequelae resolve within one year. Low serum albumin levels are a significant risk factor for persistent cardiac issues in children after Kawasaki disease.
Area of Science:
- Pediatrics
- Cardiology
- Rheumatology
Background:
- Kawasaki disease is a leading cause of acquired heart disease in children.
- Cardiac sequelae are a major concern following Kawasaki disease.
- Understanding the long-term cardiac outcomes and risk factors is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of cardiac sequelae one year after Kawasaki disease onset.
- To identify risk factors associated with the development and persistence of cardiac sequelae.
Main Methods:
- A nationwide survey identified 87 hospitals for a retrospective study.
- 1594 patients diagnosed with Kawasaki disease in 1996 were included.
- Cardiac sequelae within one year of onset were assessed via mail survey.
Main Results:
- The prevalence of cardiac sequelae decreased from 10.2% at one month to 4.2% at one year.
- Approximately 60.7% of initial cardiac sequelae resolved within one year.
- Low serum albumin levels were identified as a significant risk factor for persistent cardiac sequelae.
- Higher prevalence was observed in males and in younger (<1 year) and older (≥5 years) age groups.
Conclusions:
- A significant proportion of Kawasaki disease-related cardiac sequelae resolve within one year.
- Low serum albumin is a key predictor of persistent cardiac sequelae.
- Early identification and management of risk factors like low albumin may improve long-term cardiac outcomes.
Objective:
To measure the prevalence of cardiac sequelae 1 y after the onset of Kawasaki disease and determine the risk factors associated with these cardiac sequelae.
Material And Methods:
1594 patients who initially visited one of the 87 target hospitals in 1996 for Kawasaki disease participated. Selection of the target hospitals was based on a nationwide survey. The patients were followed-up and information concerning cardiac sequelae occurring within 1 y of onset was obtained by mail survey.
Results:
The prevalence of cardiac sequelae 1 mo after onset was 10.2% and decreased to 4.2% in 1 y. The prevalence was higher among males than females and higher in patients less than 1 y and 5 ys or older than in 1-4 year-olds. Of the patients with cardiac sequelae at 1 mo, the sequelae disappeared in 60.7% after 1 y. Analysis revealed low serum albumin as a risk factor related to the occurrence of cardiac sequelae 1 y after onset. Of the 1594 patients, 10 had giant anuerysms and 3 had a fatal outcome.
Conclusions:
Approximately 60% of cardiac sequelae due to Kawasaki disease that developed within 1 mo after onset disappeared in 1 y. The odds ratio was significantly higher among patients with a low serum albumin level 1 y after onset.
