Although acute cardiac abnormalities usually resolve, the long-term cardiovascular consequences of MIS-C remain uncertain. Previous follow-up of this cohort 2 years after MIS-C identified signs of subclinical cardiovascular abnormalities compared with healthy controls.\n\nThis cross-sectional study aims to evaluate cardiovascular health in individuals 5 years after MIS-C.
