Summary

This study looks at why some children and teens feel short of breath or have trouble exercising after their first blood clot in the leg (deep vein thrombosis) or lung (pulmonary embolism). Researchers will measure exercise capacity and breathing using special tests. The goal is to better understand these long-term effects, not to test a new treatment.
