    Jenn ... I hope this helps. If not, I am sure others will post and either correct me and/or add additional information!

    Hypertrophic cardiomyopathy (HCM) is a form of cardiomyopathy in which the walls of the heart's chambers thicken abnormally. Other names for hypertrophic cardiomyopathy are idiopathic hypertrophic subaortic stenosis (IHSS); Hypertensive hypertrophic cardiomyopathy; and asymmetrical septal hypertrophy.

    Hypertrophic cardiomyopathy usually appears in young people, often in athletes. For this reason it is sometimes called athletic heart muscle disease. However, people of any age can develop hypertrophic cardiomyopathy. The American Heart Association reports that 36% of young athletes who die suddenly have probable or definite hypertrophic cardiomyopathy. Hypertrophic cardiomyopathy is the result of abnormal growth of the heart muscle cells. The wall between the heart's chambers (the septum) may become so thickened that it blocks the flow of blood through the lower left chamber (left ventricle). The thickened wall may push on the heart valve between the two left heart chambers (mitral valve), making it leaky. The thickened muscle walls also prevent the heart from stretching as much as it should to fill with blood.

    Cardiomegaly: A medical term ending in "-megaly" indicates abnormal enlargement of the organ or structure referred to in the first part of the word. Cardio refers to the heart. Hence, cardiomegaly means an enlarged heart. (Cardiomegaly is also called megalocardia.)

    Athlete's heart: Cardiomegaly as stated above is an abnormal enlargement of the heart. Mild cardiomegaly is common in athletes. HCM is thought to cause one out of every three cases of sudden death among athletes, and approximately one person in 500 births is affected by HCM. Athletes with HCM are at greater risk because the two factors that are thought to trigger a catastrophic event in a hypertrophied heart muscle that characterizes this condition are dehydration and increased adrenaline. Both are common situations during physical exertion.

    I read that it's a nightmare for cardiologists to distinguish between this and "athlete's heart", in which the heart is healthy and large from training.

    Dear Jenn,

    Please read the overview of HCM on this web site for the definition of HCM. As for athlete's heart --this is a condition where the heart walls thicken in response to serious training --like for the Olympics or professional sports. Athlete's heart almost always go back to normal or almost normal thicknesses after they stop training for a few months AND the thickening is uniform and retains the normal shape and functioning of the heart. Furthermore, the actual muscle tissue is normal, where in HCM it is not.

    Cardiomegaly literally means big heart, but I suspect that they use this term when they don't know why its big. I think Lisa will have more info onthis one than I do --cause I have zippo (not even a web search was very helpful).

    I think Sarah's right about they're using cardiomegaly to mean big heart when they don't know why it's big. I just got my son's EKG and ECG back, and on the EKG it read "cardiomegaly" but on the echo it was more specific "hypertrophic cardiomyopathy - moderate septal hypertrophy."

    Dear Krista

    Have you and your husband been screened and are you all seeing specialists?

    Hi Sarah,

    I've posted before but it's been awhile. Our son Seamus died at 6 weeks old in June. My husband had chest pains in July so he got an echo done at a primary care center near us. They definately weren't HCM specialists, but his numbers were all well within the "normal" ranges so I don't think he needs to be re-tested.

    For myself, I've talked with Lisa and gotten the name of a specialist near us but haven't seen him yet. His receptionist said they required a referral from my doctor so I'm trying to find someone who's willing to refer me. I actually just started trying this week because we didn't have our son's medical records before then and I really didn't know where to start. (My "doctor" is an Ob/Gyn practice of 5 doctors.) If the Ob/Gyn practice won't give a referral (their receptionist said they "don't do" referrals and I'm waiting on a call back from one of the doctors), I guess I'll try Seamus' pediatrician next.

    At least it's not an insurance issue. I'm in a point of service plan and the specialist Lisa mentioned is even a participating physician.

    Dear Krista,

    Ob/gyn's are not internists. You should have a regular primary care physican. That is who can write a referral for you and someone you should have anyway. Your insurance company will have a list of PCPs near you to choose from. They maybe even have a list on their web site.

    good luck,

    S
