Multisystem Inflammatory Syndrome in Children and Cardiac Involvement: A Quaternary Center Experience.

We prospectively analyzed clinical and laboratory characteristics associated with cardiac involvement and severe presentation in multisystem inflammatory syndrome in children. Of 146 patients, 66 (45.2%) had cardiac dysfunction and 26 (17.8%) had coronary artery abnormalities. Lower serum albumin levels, absolute lymphocyte and platelet counts, and elevated ferritin, fibrinogen, d-dimer and interleukin-6 levels were associated with cardiac dysfunction. Possible treatment complications were identified.
