Two questions:

1) I don't want to take the drugs.  Anybody disagree?

2) Could the slight cardiomyopathy be a result of my twice a week high
intensity weight training?  So rather than being indicative of a problem,
could it actually be a GOOD thing?

He did mention that it might be slightly overized since I used to be a
competitive runner, but that was 18 years ago now.

Thoughts?
Jim, I do not think it wise to solicit this kind of advice from a friggin' email list no matter how astute some of the members may be on dietary issues.  Your emails seem to evidence incomplete communication between you and your doc.  You should be seeking a second opinion from a good cardiologist to determine whether you have a cardiac issue or not.  If you do have some from of cardiomyopthy (cardiomegaly is actually the generic term for a large heart, diet may help but you may well need other interventions as well.  we need to integrate our preferences on diet issues with the better aspects of what modern medicine has to offer.  Everyone has medical stories that tend to dismiss the profession but the science is there to tell you whether you have an issue or not.  do yourself a favor and get a good diagnosis.  Rick
