COVID-19 Poses Threat for Heart Dysfunction in Children

Font : A-A+

Highlights:
  • Multisystem inflammatory syndrome in children (MIS-C) is also known as pediatric inflammatory multisystem syndrome that is associated with hyperinflammatory condition among children post-COVID-19
  • Children with MIS-C are at risk of heart dysfunction post-COVID-19 infection
  • 20% of children display signs of abnormal heart function requiring a life support machine called “ECMO” to survive

Multisystem Inflammatory Syndrome in Children (MIS-C) has been a mysteriously rare and frightening consequence of COVID-19 and poses a high risk for undergoing a reduction in heart function (or heart dysfunction) among children, as per a study at Children's Hospital, Michigan. This makes it tough for the heart to pump adequate blood to the body.

What is MIS-C?

Multisystem inflammatory syndrome in children (MIS-C) is also known as a pediatric inflammatory multisystem syndrome that is temporally associated with hyperinflammatory conditions among children post COVID-19.

MIS-C has features related to those of Kawasaki disease (it involves the skin, mouth, and lymph nodes) and toxic shock syndrome (complication of bacterial infection). Due to the involvement of multiple systems and imprecise mechanisms, it is important to define this syndrome and its risk factors, so that treatment interventions can be adjusted subsequently.

Heart Dysfunction with MIS-C

"After they get exposure or get COVID-19, then about three to six weeks later the immune system mounts this very acute, hyperacute reaction and that leads to inflammation of multiple organs in the body including heart," says Dr. Gautam Singh, lead author of the study and chief of Paediatric cardiology, Children's Hospital, Michigan.

The study investigated 54 children with MIS-C who were admitted to Children's Hospital last year. It was found that the majority of the kids' heart and blood vessels were affected and some even required a life support machine called "Extracorporeal membrane oxygenation(ECMO)" to survive.

Even among the 20% of the children who seemed to fully recover, had signs of abnormal heart function on ultrasounds. Hence they were followed up and by the end of six months, they fully recovered.

Although COVID doesn't cause serious complexities in most children, the present study stresses the need for adults to continue guarding these young ones by getting themselves and their children vaccinated.

Other Manifestations of MIS-C

Managing COVID-19

  • With unpredictable effects of the coronavirus, the best way to keep it at bay is to follow COVID-appropriate safety practices like wearing a mask, regularly cleaning your hands, and coughing into a bent elbow or tissue along with physical distancing (6 feet about 2 arm's length), that may help evade the severity of COVID-19 infection
  • Avoid the crowd and keep away from gatherings
  • Staying home as far as possible in properly ventilated spaces
  • Seek medical advice at the earliest if any symptoms suspected of COVID-19
  • Sustain a healthy diet to boost up your immune system
