Predictors of coronary artery aneurysms in Kawasaki disease

Area of Science:

• Pediatrics
• Cardiology
• Infectious Diseases

Background:

• Kawasaki disease (KD) is a leading cause of acquired heart disease in children.
• Coronary artery abnormalities are a significant complication of KD, leading to long-term cardiovascular morbidity.
• Limited research exists on risk factors for coronary involvement specifically in Indian pediatric populations.

Purpose of the Study:

• To prospectively identify and stratify clinical and laboratory risk factors associated with coronary artery involvement in Indian children diagnosed with Kawasaki disease.
• To provide data that can aid in early risk stratification and management of Kawasaki disease in this population.

Main Methods:

• Prospective observational study conducted between October 2009 and November 2011.
• Inclusion of children admitted with a diagnosis of Kawasaki disease at a tertiary care hospital.
• Tabulation of clinical details, laboratory investigations, and echocardiographic findings to assess coronary artery status.

Main Results:

• Out of 37 children with Kawasaki disease, 8 (21%) exhibited coronary artery abnormalities.
• Prolonged fever, wider dispersion of symptoms, and the presence of pyuria were found to be significantly associated with coronary lesions.
• These clinical and laboratory findings represent key indicators for increased risk.

Conclusions:

• Prolonged fever, widespread symptoms, and pyuria are significant risk factors for developing coronary artery lesions in children with Kawasaki disease in India.
• Early identification of these risk factors can guide aggressive management strategies.
• Timely intervention based on these indicators may help prevent irreversible cardiac damage and improve patient outcomes.
