Children have been found with damaged hearts several months after receiving Covid vaccines, an extended new study shows.
Researchers followed a group of 40 patients aged 12 to 18 for up to one year after the children were diagnosed with myocarditis.
Myocarditis is an inflammation of the heart muscle (myocardium) that can reduce the ability to pump blood, according to Mayo Clinic.
The inflammation can cause chest pain, shortness of breath, and rapid or irregular heart rhythms (arrhythmias).
Severe myocarditis weakens the heart so that the rest of the body doesn’t get enough blood.
Clots can form in the heart, leading to a stroke, heart attack, and possibly death.
Myocarditis is a known side effect of Covid shots, according to the U.S. Centers for Disease Control and Prevention (CDC).
The new study has found that some children who experienced heart inflammation after Covid vaccinations had scarring on their hearts several months later.
Researchers monitored the group of vaxxed children who suffered heart inflammation after they had received an mRNA shot from Pfizer or Moderna.
They conducted a series of tests, including echocardiograms.
Cardiac MRIs were performed on 39 of the 40 patients.
In the group of 39 kids who were imaged, 26 showed abnormal results.
Of those 26, 19 had late gadolinium enhancement (LGE) or signs of scarring on their hearts.
