I'm 12 years old and have hypertrophic cardio myopathy, my dad, grandad and other members of my family have it. My dad wasent effected untill his 40's and my granda his 60's, also my cousin died when he was a baby from it anyway what I'm saying is will it get worse, it's not that bad at the moment but I don't play many sports will I have to stop most of my activities?
