Is this trial a fit for you?

Likely a good fit

Children and adolescents who previously had MIS-C and were hospitalized at the Medical University of Warsaw between October 2020 and February 2021, plus age- and sex-mec matching healthy controls.

Probably not a fit

Individuals with no history of MIS-C or those with significant pre-existing heart disease or chronic conditions may not derive a cardiovascular benefit from participation.

What this trial studies

This cross-sectional study compares cardiovascular health in individuals five years after MIS-C to age- and sex-matched healthy controls. Researchers will use imaging, vascular assessments, cardiopulmonary exercise testing, and biomarkers of endothelial injury to characterize long-term cardiovascular status. The study builds on prior follow-up at two years by examining whether subclinical abnormalities persist into longer-term follow-up. Participants with a history of MIS-C were hospitalized at a Warsaw pediatric center between late 2020 and early 2021, and controls are recruited from primary care clinics. No interventions are being tested; the goal is to describe long-term cardiovascular outcomes in a real-world setting.

Why it matters

Potential benefit: If successful, the study could clarify whether MIS-C survivors require ongoing cardiovascular monitoring years after infection.

How similar studies have gone: Earlier follow-up suggested persistent subclinical cardiovascular changes; this study extends observation to five years to confirm durability of findings.
