a 14 yr old is old enough in some areas to be considered an adult so a 14 yr old should be mature enough to know what she should and should not have. It's her parents job to raise her to know that. If by 14, that has not happened, then she parents should have some fault. I know I'm not that old. I'm only 26, but I know at 14 I knew what I could and could not have. I have asthma and a lot of allergies. By 14, I knew what to avoid because I knew what would and would not induce asthma attacks because that's what my parents and doctors taught me. So with a heart condition, she should have known better.
