Young people have died of undetected congenital heart disease for as long as people have had hearts.
Heart defects I mean
covid shots?
Sadly, yes. When I was in boot camp an 18 year old kid in my company had a heart attack during a 2 mile run. Thankfully he survived. They put him in a medical holding company until he had 6 months service (so he could qualify as a veteran) and then discharged him medically.
