Post Kawasaki disease exercise capacity

Abstract

There have been questions about the long-term impact of Kawasaki disease on the heart. This impact could take many forms, but one is a decrease in exercise capacity. It seems possible that the degree to which the coronary arteries are affected during the acute illness might be related. In this volume of The Journal, Tuan et al sought to evaluate exercise capacity between patients post Kawasaki disease with different coronary artery diameters. The diameter was evaluated using the lambda-mu-sigma (LMS) method. They found that those with greater coronary artery diameter had lower peak exercise capacity than those with lower coronary artery diameter. These results suggest that there may be longer term adverse effects for patients post Kawasaki disease with larger coronary artery dimensions. It remains to be seen if this is a physiologic response or possibly a reflection of different levels of physical activity between the groups. These results emphasize the need for longer term longitudinal studies to evaluate exercise capacity in patients post Kawasaki disease.
