my son had cardiomyopathy due to probable myocarditis. He was much younger than you, though. He was eight months old when he got the flu and they said it affected his heart. In the hospital they had him on some pretty hardcore drugs but he recovered abnormally well. The doctors told my husband and I that some people get better, some worse and some stay the same. If he got worse and it couldn't be managed with meds then he would need a transplant. Since he was doing so well, when he came home the only two drugs he was on were digoxin, which is for congestive heart failure and captopril which is a blood pressure medication. After going for follow-up echos several times he was weaned off of the medications and now they tell us that his heart is fine. I'm sure that we were very fortunate especially with him being so little.
