New research: Post-Covid review in children finds severe heart damage

“According to the literature, children did not need to exhibit the classic upper respiratory symptoms of Covid-19 to develop MIS-C, which is frightening. Children might have no symptoms, no one knew they had the disease, and a few weeks later, they may develop this exaggerated inflammation in the body,” Moreira said in a statement.

The team reviewed 662 MIS-C cases reported worldwide between January 1 and July 25. Eleven of the children died. Ninety per cent had an ECG test and 54% of the results were abnormal.

The heart damage included:

• Dilation of coronary blood vessels, a phenomenon also seen in Kawasaki disease.
• Depressed ejection fraction, indicating a reduced ability for the heart to pump oxygenated blood to tissues.
