Hey na, Welcome to healing well forum. Sorry about your friend. I would suggest perhaps try Googling asymptomatic cardiac enlargement you may be surprised at the amount of information you get there. This site is really a great site but you may find a shortage of people who have this disorder or who know of it. And really we can only give suggests and support...not diagnose or anything such as that.
Good luck and please do keep us posted. Take care
