Testing a cholesterol medication to protect children's heart arteries after Kawasaki disease

This trial is testing whether atorvastatin — a medication commonly used to manage cholesterol in adults — can help protect the heart arteries of children who have had Kawasaki disease and developed coronary artery problems. Researchers believe this medication may reduce inflammation and strengthen the blood vessel walls in these children's hearts. The study will compare different doses of the medication against standard care alone to see which approach works best.

Kawasaki disease is a serious childhood illness that can damage the coronary arteries (blood vessels supplying the heart), leading to life-threatening heart problems. While current treatments help, some children still develop dangerous complications. This medication has shown promise in early studies for reducing inflammation and improving heart vessel health, so researchers want to formally test whether it should become part of standard care for affected children.
